Yep, 7900GTO is just and underclocked 7900GTX ... I see no h/w differences ...

[webwilli]

more results please :D

which sli-mod-driver?

[Fr3ak]

Thats really a nice and cheap card. Have you tried what its max oc is?

[hot_fifty]

guess he used the 85.96 mod-driver

[Marvin_The_Martian]

Are these the cards sold on ocuk now for 200E?

Samsung lists these chips at 900 MHz. :woot:
I just installed one of those myself. :D
Full fledged GTX at 249€ + shipping !

Are 720/880Mhz the max stable benchable clocks or are you still testing?
Looking very good so far :D

[webwilli]

stock cooling?

very very nice....

i have ordered two of these :D

Bios 0212? can you send it me please?

Hmm, could someone point me GTX bios for this card?
And does this card really support HDCP?

Will these be under $300?

[Fr3ak]

They are 225-250€ over here,so I d say yes they will.

Looks like I know what my next card is.

[WeStSiDePLaYa]

when are these available and for what north american price? i just bought a 7900GS and now im kinda sad.

[afireinside]

Maybe the GTO BIOS runs looser mem timings? Not sure about the core though that's weird.

I want these to be out in the US now :D

[johnnyliu3377]

I still need the 7900 GTO BIOS .... PLEASE ... anyone... :(

[Littleluk]

Why do you have to flash the bios? Why don't you simply set the memory clock higher?

I'm thinking about to sell my two OC'ed 7800 GT and to get a 7900GTO, what do you think about that?

Is the first Stock 7900GTO 3D Mark 06 Bench in SLI Mode or single card?

This is 06 Bench in single card!

[tvdang7]

then whats the diff between these and the 7950 gt? both are underclocked gtx's

[VASkO]

the 7950gt isn't an underclocked GTX, it has only 1.4ns RAM, the GTO has 1.1ns and same PCB as the GTX.

[Littleluk]

but it's still slower than two 7800gt isnt it?

[DCR]

but it's still slower than two 7800gt isnt it?

Possibly, but what about the single card price?

Is this available in North America?

[mrkram]

anyone know if you get the same results with the evga variant? or is this MSI having too many 7900gtx's laying around and rebranding them as 7900gto's?

[DCR]

I ordered the EVGA, so I'll find out soon.

The specs for the card look identical for both though.

[aspevacek]

I am wondering if it can be run in SLi with my current 7900GTX? Has anyone tried yet. I am not against doing a volt mod to get the clocks where they need to be.

[rozzyroz]

omg, i just bought 2 of the evga one's. these seem to be the best bang for the buck out there now. i dont even think ill need to flash to gtx (the evga may not be able to anyways).

i was trying to hold off, but this seemed like a nice upgrade from my PM @ 2.4 and x800xt.... e6600, 2x7900gto, 2gb gskill pc6400.

[afireinside]

Is there any difference between GTO and GTX BIOS other than voltages?

[gr8golf]

I'd like to know this too - I'm in the same boat as afireinside. I'd prefer to just overclock my eVGA 7900GTO that is on the way rather than flash the BIOS. I am planning on sending it in on the step up program and worry that the different BIOS could negate the program.

[afireinside]

What are you stepping up to... already :lol:

I don't want to flash GTX BIOS as that will put me in GTX class on ORB. I'm vmodding anyway so if it's just voltage who cares.

Well - I am sorta expecting that the G80 will release about 48 hours after I get my 7900 GTO installed, LOL! Isn't that how it always goes? I didn't want to spring for a 7950GX2 or a 1950XTX right before the DX10 cards came available but I needed something decent to drive me @ 1680x1050 until the next gen cards show up. I'd like for this card to clock up to 7900GTX levels and that would do the trick.

well for dx10 cards to work fully dont we HAVE to have vista? im not going vista in a while . i dont want to pay alot of money and i want it to work out the kinks first. so dx9 will be fine for me unless im mistaken.

[gr8golf]

I'd agree with everything you just said - and then if Vista releases in 1st quarter next year and there is a killer game that I can't live without I'll be right there on the bleeding edge.

Also - as is usually the case, the next gen cards will run DX9 better than then current cards AND will be future proof *sorta*. Basically, everyone will be rushing out to get the latest and greatest and will be trying to catch up with me. Wish I could be more patient

[luismenendez]

I don't see the point on buying an expensive gfx with DX10 before you have a DX10 game to play.

That's why I bought a 7900gto :p:

It should do 900 right? :confused:

thats when i gave here the "go big or stay home!" speach:fact:

btw newegg has these for $245 as of today.

[rpg711]

i like msi more than evga because evga products have tendencys to blow (7900gt)
msi stuff is hardy... too bad there arnt 7900gto msi here in america... we have evga 7900gtos
i guess ill jump for this
i mean, coolaler had 7k '06
that is insane... for one card
two would mean almost 14k!!!
i guess ill go for this instead of x1900xt or anything else
now to wait untill it gets down to 199... (Im a poor teenager with no job)

[The Dome]

any news on the eVGA flavors yet? I have two on the way...

[DCR]

I get mine tomorrow, but I won't have it running until the weekend. I expect the card to be the same as the MSI.

[gundamit]

btw newegg has these for $245 as of today.

I don't see the MSI version but the eVGA 512-P2-N573-AR Geforce 7900GTO 512MB 256-bit GDDR3 PCI Express x16 Video Card - Retail (http://www.newegg.com/Product/Product.asp?Item=N82E16814130065) is $256 shipped. 99+ units in stock as of right now, so no rush needed. So MSRP is $250, which makes this card a killer deal if anyone puts it on sale. That might not happen depending on what kind of numbers are in the retail channel. Too late for me. I already pulled the trigger on two. :rolleyes:

Gah. I hope these are just reflashed 7900GTX that they needed to get out of the retail channel. There couldn't be enough cores that failed to meet required specs to launch yet another model from multiple vendors.

EDIT: Seems as though the Samsung memory was the issue, therefore the spec change on the bios is memory speed.

[luismenendez]

I'll tell you what's XTREME...

I haven't told my one :D

She would kill me; its my 3rd GFX this year!!!

anyway xtreme (at least for me) does not mean wasting money just to be the first to show off a DX10 GFX running on DX9 games. xtreme waste of money I would say ;) but xtreme

[mascaras]

the 7950gt isn't an underclocked GTX, it has only 1.4ns RAM, the GTO has 1.1ns and same PCB as the GTX.

regardsMy MSI GTO has 1.1 for sure, I checked today :)

And about not telling the wife/girl... why not?

I used to own a 7900GT and I sold it for 220 euros... paid 242.40 euros for this GTO :D lol... not a bad deal imho ;)

I must say those 3 little chips get very hot indeed... too hot to hold on to
Where normally the little black sink sits, but then on the other side of the card, right between the plastic push pins... unfortunately they're quite small and there's a resistor next to each of them... and the resistor is taller/higher than those chips so they're very very difficult to cool :stick:

[gundamit]

And about not telling the wife/girl... You're not telling either one? :D

I got my cards today. They have the GTO stickers on the front but they're have 7900GTX everywhere else. Even if I get the Sammies with issues not a bad deal for a gaming rig. :toast:

[HeavyH20]

It should do 900 right? :confused:

No chance of that, not without a volt mod. They physically reworked the cards. The memory maybe 1.1 ns Samsung GDDR3, but with 1.4 ns timings and voltage (1.9V).

[Garrett]

I was thinking exactly the same HeavyH20...

It's like BH5 mem, that can do 260 to 270 with 2-2-2 timings @ about 3.6v... BUT if you turn the volts down all the way to 2.9 they'd never do 260 2-2-2... unless you've got magic sticks :D

This memory needs a voltmod then, otherwise it won't reach its "rated" speeds.
But will this memory die as fast as with a lot of 7900GT cards?
I'd rather not sacrifice this card

Hmmm... default voltage of the 7900GTX mem is 2.12v... this card however measures 1.81v :eek:
Now my question is: what voltage is the absolute limit for 24/7 use :confused:

[dawnz]

is it a risk ? flashing the 7900GTO into a 7900GTX ?

[luismenendez]

My MSI7900GTO overclocks the memory to only 1638 when Atitool crash but the timmings looks tighter than samsung specifications (batch BJ11):

trc: 31 (35) trcdrd: 10 (12)
Trfc: 39 (45) trcdwr: 6 (8)
tras: 22 (25) trrd: 10 (8)
trp: 9 (10)

http://www.samsung.com/products/semiconductor/GraphicsMemory/GDDR3SDRAM/512Mbit/K4J52324QC/K4J52324QC.htm#sp

in the link above we can read that the timmings of my GTO are the one used for the BC14 which run at 1400 Mhz

I wonder if relaxing the timmings can give 1800 Mhz as the 1.1 ns samsung volts specificatios are 2.0 v +/- 0.1

could anybody post the details timmings of a 7900GTX using Nibitor????

Ive just done the mod that johnny posted with a pencil (HB couldnt find a 2B). Got it up and running at 2.03V... will have a play around later on with a 2b if i find one. Its definatly helped because on the stock 7900GTO bios im hitting higher frequerncys than when i was using a 7900GTX bios with relaxed timings.

Is it better to have 0 Delta in bios or not?

[Micketh]

Of course I will... just playing with a GTX bios now. Give me some time to get my stuff together and I#ll have a bash.

[Micketh]

I worked from the top down to get these numbers.

Cooling Stock AIR | Bios MSI 7900GTX Rev 2 | Delta 50

Mem 2.03v
875 Very minimal but noticable at times
870 Say 1 or 2
865 Completly artifact free and playable

Core 1.4v
720 Artifacts in menu
715 Minor artifacts in game
710 Perfectly fine

F.E.A.R loves it @
710/865 (1730)

Before the mod artifacts would apear above 695/1680 in F.E.A.R on same bios. On stock bios the same numbers were achieved.

3DMark 05... basically I threw it in at the deepend with 710/875 and it got thought it ok but with serious artifacts appearing.

The score is low because what you see open is what I left open I was just trying to see how stable the card was also the CPu is only at 2.5 for the moment.

So pencils work? Nice.. How many times do you have to ''stroke'' it?

My GTO is currently in its box, it doesn't function properly. Screen sometimes flashes black.

Is this pencil mode or what?

[Garrett]

When I penciled I got a LOWER voltage.... duh of course!!
The picture says 1.2k to 1.8k
1.2k is the standard resistance indeed!
With penciling you LOWER the resistance... somehow in this case with a HIGHER resistance the voltage goes up, must have to do with the PCB layout or whatever... so penciling in this (my) case gives lower voltages... not good :p:

You know... f**k it... it's a 242 euros card, it runs 700/800 without a sweat and I'm satisfied... no soldering on this one no sir ;)

[vyper]

use flat-iron


penciled is will not do, Because resistor is value to increase

Can anyone point a noob in the direction of flat-iron vmodding tutorials?! :confused:

Try not to do any SMD soldering/unsoldering if you have no experience ;)

True, but be careful, those SMDs are small and not so easy to solder, no space around them for error ;)

You could practice on an old card.. I have a dead 6800GT lying around, but I can't solder smd components, I can hardly voltmod lol :D

[vyper]

Just to clarify: to get 7900GTX performance out of the EVGA 7900GTO can you simply flash the bios with the GTX bios and clock it, or do you need to perform a v-mem mod like johnnyliu3377 did?

[Garrett]

If it can run GTX speeds then you obviously don't need to flash the BIOS... flashing the BIOS will most likely not improve the overclocking abilities of the card anyway.
If you flash it to GTX however, you can run SLI with a 'real' GTX... that's the only reason I would flash, if I had bought a GTX previously.

[The Dome]

Has anyone have trouble with these cards not switching from 2d speeds to 3d speeds? For some reason both cards refuse to change from their 275Mhz 2D core speed when any 3d app is run (3Dmark,Aquamark,Oblivion and so on..) so I have been getting some terrible results (65K in Aquamark). I also have no way of changing the clocks as the 2d-3d performance tab does not show up in the overclocking tab (tried about 5 different sets of drivers). Sorry if this is too off topic?

[Garrett]

Have you tried Rivatuner?
Works flawlessly here...
I can check it with MBM5... I have the MBM which displays all of the DFI sensors correctly :thumbsup:
PM me if you want more help

[johnnyliu3377]

The originally GTX resistor set value:
http://my.so-net.net.tw/johnnyliu/7900GTO/7900gto.mod.JPG

on the left resistor is 1k ,the right side is 560 ohm

than GTO is left 1.2k and right is 1k ohm

[johnnyliu3377]

than GTO is left 1.2k and right is 1k ohm

oh.....So pencils use on right 1k ohm, maybe mod is okay!

[Alexandrus]

So what do these resistors do ? Do they affect the Vmem in any way ?

[SF3D]

-johnnyliu3377-

You have both cards, GTX and GTO?

Can you confirm this?

51961

In GTO 1.2Kohm SMD resistor is REFIN value to ILS6534. Refin value affect FB2 value, which is VDDR out.

51962

Is there any other differences between GTX and GTO?

If I get enough information I will make Vmem mod guide to Xtreme mods section :D

I have to RMA my card, was there from start, high pitched noise during some games in the menus, or animations or when loading up new maps etc (rarely during ingame tho). Faulty cap(s), like 90% sure:

Here's an example I recorded with a mic from FEAR menu http://media.putfile.com/fear-valikoima

Such a shame, clocked up to 700/850 on stock volts & bios... :(

Please Nvidia use better quality on the caps in future thx. :p:

[Garrett]

Oh that sux indeed... well you shouldn't have any problem RMA'ing it :)
Good luck with the next one :thumbsup:

[Alexandrus]

Does it do the same when running at stock speeds ?

[RPGWiZaRD]

Does it do the same when running at stock speeds ?

Yes it's pretty much as audible (maybe SLIGHTLY less) even if I underclock it, got extra cooling over the card too but it doesn't appear to be a heat issue. It's just the typical noise of faulty caps when enough power running tru them, in some games and types of renderings the certain caps become more stressed so I'm sure it's just a faulty cap(s) on the card and been there from start. Wouldn't wanna replace it just cuz of that tho but yea I dunno what else to do that could garantuee I'd get that noise away.

I have no trouble standing the constant noise of blowing fans but high pitched noise like this is a no no.

I bought this card as a quick replacement for my rocksolid 6800GT since I needed something faster quickly since I'm going to the army in january so I want to use this new card as long as possible b4 but of course I always have this bad luck, now I just hope that next 100 card shipment arrives very soon to the site where I bought this one from or I could try and demand the money back and buy elsewhere in that case it takes more than a few days...

[Alexandrus]

Sorry to hear that.
If you knew where the sound is coming from you could change the caps, but it's very hard to determine unfortunately.

So YES people you can pencil the mem voltage :thumbsup:

I'm not going higher than 2.00v because I'm afraid the mem may be 'second rated' or behave 'strange' when you feed it "GTX voltage"... as in 2.12v... ;)

Thanks Garrett for the clear pics and results. :clap:

Don't you have 1.1ns on your GTO? Isn't the stock 2.0v and max 2.1v?

Are you going to change the mem timings too to match the tighter timings on the GTX?

[Alexandrus]

The GTX does not have tighter timmings, it's the opposite, the GTO has the tighter setting for the RAM but the lower frequency.

What was mem OC before pencil actios (artefact free) ??

[Garrett]

That's something I don't know precisely...
I run it @ 1600 for 24/7 use, haven't really tried higher, however Atitool started artifacting with little yellow dots at around 1700... now it starts that around 1800.
However in 3dmark I have yet to see 1 artifact :)

Pencil it and try 2.00v or so... you'll definitely see improvement
My 1.1ns runs quite nice apparently, definitely NOT disappointed with this card... I don't know if 'real' GTX mem runs that much better ;) :)

[Alexandrus]

Apparently OC works quite well with standard GTO BIOS and timmings.
In some cases, GTX clock are achieved with no modding at all, no extra voltage, nothing. Maybe if you're aiming for over 850MHz on the RAM, timmings could use a little adjustment.

Good going Garrett, really nice OC from a 250$ card ;)
What did you use for the pencil mod by the way ?

[Nazu]

Is is possible to flash the bios in Windows like with Ati cards? Here are my scores (I know the cpu is a serious bottleneck :( ) :

3Dmark 05 (http://koti.mbnet.fi/nazu/Kone/05mark%204.jpg)

I thought I had a 2B lying around her somewhere, but it looks exactly like the 8B, except for the indication on the back, but this 8B works too, apparently :D
Yeah I really dig the price of this card, 242 euros :)
I remember last year November when a 7800GTX 512 was still 749 euros :eek:
Look what you get for 1/3 of that price now :D

[PiLsY]

Garret, I have exactly the same issue - running the artifact scan in ati tool shows a few little yellow dots (3 or 4). However, they are not detected as artifacts and i've not had any problems in any other benchmarks. If I drop my core clock down to sub 350mhz they don't appear, the higher over 350 I go the sooner they appear (it takes an hour at 600mhz for the dots to appear). Then again my GTO has a very poor core - I can only do 665mhz without it eventually overheating and artifacting / crashing. Messed about with the delta in bios and its not that - infact i've changed my delta to 75 for 650/650/725. Core temp gets to 67c after 30 mins and stays there. I think Im getting poor core contact, but can't risk taking the heatsink off incase I rip those memory pads..have nothing to replace them with. Memory is happy at 851mhz, so I've lucked out there though. From what I saw of the core oc increase in scores though I'd much rather have the ram clock well than the core. Course, both would be nice :).

Matt.

[SerialSniper]

johnnyliu3377, have you benched the gtx vs the gto @ same clocks?

Would be interesting.

I don't understand why nvidia has released a 240€ card that is so similar to a +-450€ card. I can only think that it is to make way for their dx10 flagship 8800GTX?

Anyone gone from a 7900GT 700/900ish to 7900GTO?

[HeavyH20]

Well, instead of loosening the timings via BIOS edit or flashing the card with the GTX timings which are too loose, I took a different tact and tightened the timings. It did not affect the memory clocks and improved in game performance as well as benchmark tests.

Timings:

timing-----------GTX-------GTO---------BJ11 ------ BC14-------Mod
tRAS------------24-----------22----------25---------22---------19
tRC-------------34-----------31----------35----------31--------27

Not both :)
I'm actually surprised to reach 905 with tighter (1.4ns) timings at 'only' 1.95v... but hey I won't complain :thumbsup:

@ PiLsY:
You won't rip the white memory pads just like that, just be careful :)
When you remove the cooler they're 100% intact, tried it on my 6800GT back in the days, and with this card, no problem :)
Just be very gentle when lifting the pads off the cooler or the card's memory, sometimes they stick on the cooler, sometimes on the memory.
If you're careful it should be ok, then put them on the cooler, put the cooler upside down in a safe place and apply alternative cooling ;)

[GOESA]

What did you get before you tightend up the timings? in 3dmark and such I mean...

[Garrett]

I've tried some resistances and voltages:
792 ohm gives 1.98v and 748 ohm gives 2.02v for the memory :)
Hope this helps some people :)
So ~770 should give 2.00v I guess...

Pencilled the resistor to 0.759 which gave me 2.03v vmem.

400 points in 3Dmark05, 250 in 06 and 25 fps peak (4 fps average) in COH.

[PiLsY]

Tbh I'm not too concerned about a few yellow dots in ATI tool - I don't spend much time using it :). All my games run perfectly as does 3dmark etc. Incidentally, I'm using the 91.47 dets off the nvidia page.

At the moment I'm so cpu limited (3700+ SD @ 2.75ish) there really wouldn't be much improvement in getting the clocks up any more. Cheap ram too (233@3/3/3/9) and the board doesn't seem the best at cpu clocking as well (A8R32-MVP) as going from 1.45v to 1.55v gets me a whole 10mhz. I'll have a go at the mem mod this weekend and see what it does for me though. Having said that while the cards out I'll probably end up checking the heatsink contact anyway. If I do rip those pads what can be used as an alternative? The shin etsu pads I can get round here doesn't look thick enough?

3dmark 06 is getting me 4750, 05 I get about 11500, 03 I get 23500 and 01 I get 36000. Any "tweaks" I do now really aren't going to give me much of an improvement until that cpu gets replaced. Leaning towards an opteron 165...

It's your cpu, vyper... I had my X2 3800+ @ 2816mhz during my 12k run... X2 seems to score just a tad higher with 05 ;)

-edit-... proof of voltages :p:

[PiLsY]

Vyper : You need to set the memory timings set to 3 in the pull down box - either that or click auto select.

HeavyH2O : I tried your timings. I've got a bit of a boost in 3dmark 06 (about 350 points I think), but I'm getting artifacts now (a couple in the first test, lots in deep freeze). Will leave the modded timings on for now and try the pencil mod to stabilise it. If I can get the ram to 900mhz at these timings it should be good for 5500 in 06. I think its the TRRD setting though - I tried playing with that when I was messing with the bioses and it always gave me artifacts at anything below 10. We'll see how it responds to voltage thought before i change it back. Incidentally, TRRD from 10 to 8 alone gives you about 265 points IF you can stabilise it.

06 score is now at 5286 (http://service.futuremark.com/compare?3dm06=568566), managed to tweak over 500 points out of it last night :). I'm quite proud of that score for a single core on air with an unmodded gfx card. My whole pc cost me less than a 7950GX2 :D.

Still a little more to come after the vmem mod, hopefully some more core if I find its got poor contact. Probably just a crap GPU though. My maximum artifact frree core clock is 662mhz (24hrs of ati tool artifact scan). 666mhz artifacted a few times and 675 artifacts every 10 mins or so. Nothing noticeable as graphics corruption, but ati tool beeps at me. 685mhz I get artifacts in 3dmark.

You can edit the timmings with BIOS Editor 3.3.

That is the first timing table (set 0). The one you want to look at is the third. Here are the timings I use.

http://img218.imageshack.us/img218/638/timingsoe5.jpg

I have attached the BIOS I use. It is a 650/750 clocked BIOS with the tighter memory timings. The ZIP file is clean of any and all viruses.

Flash command:

nvflash -j -4 -5 -6 gto-tm.rom

The higher default memory clock will also allow Coolbits to clock your memory well above 800, assuming it can handle that.

[BulldogPO]

Thnx.

[PiLsY]

The tighter timings have lost me about 20mhz on the mem clock artifact free, overall the score is still up a bit though. Not messed with changing trrd back to 10 or trp back to 9 yet to see which (got a feeling its those) is causing the artifacting and what performance drop that would cause. The fact that I can bench to 866mhz with artifacts would suggest that a vmem mod would clear it up.

That 866 is with default volts? like 1.82 or so?

[PiLsY]

Garret - Yup...the memory on this card is awesome, just the core seems rubbish. I've got no working voltmeter, so I can't check the vmem, but theres no reason why it would be higher than any others as its just an off the shelf MSI. Regarding the vmem mod...seeing as i've got no voltmeter can someone give me an idea of how pencilled in the resistor should be? Im guessing 4 or 5 strokes with a 2B should be enough. Hope I've got a pencil - lol.

Been doing more testing with the modded memory timings bios. It appears I was hasty before when I claimed it gave me 350 points... I've been testing all morning to find which timing was giving me artifacts, so I've been changing every timing back to default and testing with the others tightened. It turns out its TRCDRD 9 thats causing my issue - set it to 10 and the artifacts vanished. However, during the course of the testing I came to realise that this bios is doing absolutely nothing for my scores. With default GTO bios I now get 5512 3dmarks. With the modified bios I got 5524. With modded bios and TRCDRD 10 I got 5529. With the GTO bios with TRP 8 and TRRD 9 I got 5521. The performance gain here really is negligible. However, tightening the timings can massively reduce your memory overclock, so overall its best to stick with the standard GTO bios. Its even got me wondering whether loosening timings may be a good idea. Mind you I saw no perfromance boost when I tried samsungs BJ11 settings which were conciderably looser than the GTX settings. I'll test tonight with a couple of runs on 01 and 03 using the GTO standard vs the modified bios (but trcdrd 10 so no artifacts) and post my results. I'm guessing 01 and 03 may show more of a difference due to the higher points scale, but even so, I'll be surprised if I get more than 100marks extra in 01 and 50 extra in 03.

Matt.

[HeavyH20]

What CPU are you using? Looks like your 06 score is down in the mild clocked single core territory. And, more memory clocks <> more performance. You need to balance the two.

The tRRD at 10 is 2 LOOSER than stock 1.4 ns spec. I set it to 9 to increase the clocks a tad.

I have pushed my card to 710/825 with stock voltage to score 6800 in 3DMark06.

As a tip, once you find your memory peak, roll back 10 Mhz on the memory. Scores usually improve. Even with 2.1V into the RAM, most GTX cards barely get to 850. So, just keep it balanced.

[Robbie]

Pilsy, I did this last nigh with a sharpened pencil and it seems that it is .01 volts a stroke.

[PiLsY]

Cheers Robbie - 1 stroke at a time it is then :). Which resistor did you do, the left or the right?

HeavyH20 - I'm on a 3700+ San Diego @ 2.75ghz. Also I tried TRP 8 and TRRD 9 earlier this afternoon, did absolutely nothing for my score.

Just had the heatsink off, core contact is perfect - damn. Guess I've just got a rubbish GPU. The PWM regulators underneath the little black heatsink didn't have very good contact though. The three closest to the back edge of the card weren't touchng at all - now sorted it, may help. Will post up later.

May I sincerely suggest you do NOT pencil without a Multimeter!!!!!! :nono: :nono: :fact:

[PiLsY]

Heh - dont worry I didn't go overboard.
Since reseating the heatsink my core will now clock to 680 - bonus!
However, since reseating the heatsink and doing the vmem mod my memory clock has dropped significantly - b@lls!
I've wiped the pencil mod off, but still isn't clocking like it did. Im getting artifacts at anything over 825mhz now. Before I was artifact free at 851. I can still run at 851, its just that within a minute of starting ati tool is spewing errors and trying its best to paint the furry box yellow one dot at a time...

In all honesty I may just need better cooling. My motherboard is red hot around the northbridge. The entire 7900GTO is too hot to touch after an hours gaming (I have a heatpipe burn to proove it!), and my room turns into a sweatshop if I don't have the window open - lol. GPU temp is currently @ 65c after 5 mins of ati tool.

Seems to be settling down again now. Now @ 680/840 for 30 mins no artifacts. Guess it must just be the thermal pads bedding in again. Looks like I'm 5mhz up on the core. Should be able to bench at 690/866 with severe artifacting. The vmem not helping the mem oc has me confused though. As I said before though, I'm starting to suspect temperature is to blame. GPU is now @ approx. 70c.

Those are lower than the others, be careful not to ruin the balance. The heatsink touches the first two columns closest to the GPU, the others...not.

As for better cooling, we all want it, but it's not available to buy, so you'll need to make one yourself somehow. I wanted to make my own cooling but realized the stock is very good except it does not cool the RAM as it should.

[PiLsY]

I mean better cooling in general. I need to get my case temps down so the gfx heatsink is sitting in cooler air. At the mo my case temp is approaching 40c. Ive got 2 x 120mm fans, both at about 7v and my psu, thats it. And one of the 120mm fans is in front of 4 hdds which won't be helping airflow. I think really i need to watercool it if im gonna go further (have had several wc rigs in the past). Need to get the cpu heat and northbridge heat out of the case.

[Robbie]

I am having some trouble with mine being stable now. I flashed it back to stock from 650/800, and I penciled the ram to 1.92v. I have 2 120's blowing on it, but it won't last 10 min in css without crashing. Any ideas? I have a maze4 and I will put that on it when I get my water cooling setup put together later this week. I hope this card isn't dying on me.

-rob

[PiLsY]

Robbie - have you removed the pencil mod? Also was CSS stable before the pencil mod? Other than that, try reseating the card. If neither of those work then clock down the core to say 275mhz (2d speed) for 3d and see if it still crashes. If so clock down the ram to 500. If it still crashes...errr. Not sure... :). Good luck.

Mines fine now. I think the initial problems were down to the thermal compound and pads bedding in again. Now at 680 / 850 stable and artifact free, so ive gained 5mhz core :D.

Matt.

[HeavyH20]

Some results without mods. These were so easy .....boring :rolleyes:

Maybe more results with mods later.


Yup, the power of Conroe. Looks like you gained on the CPU score of 3K. Same video performance, however, but mine was OC'd over 700. Those are killer scores for a spec run! I for one, am still stuck with a dual core Opteron for now.

[kiwi]

Sell opteron ASAP :p:

HeavyH20
I remember using your 7800gtx bios that gained 200-300 points in 05 mark at the same clocks and it clocked almost the same with tighter timings. Anything similar with GTOs for a huge score jump? :)

[HeavyH20]

It was decent until the Conroes appeared. Waiting on Kentsfield. I figure a Kentfield/G80 combo should be a decent setup for a bit. The Opteron is not worth selling. I will push it down the line to one of the other three PC's.

As for the BIOS. it was posted earlier. Using the same premise as the 7800 GTX.

And, PiLsY, the VREG cooler needs to contact all the surfaces evenly. The other flaw on the older cards was the mixing of vreg components so they were not the same height. I saw a few cards, and most of the problem cards were uneven. So, I pull the TIM off the higher ones, use a thin layer of Ceramique and use better TIM on the lower row. Keeps the pressure even.

[Robbie]

Well guys my card is dying as we speak, I took off the hs and as5'd it, and it dropped 3c idle, not bad. Then I ran 3d mark 06 and it crashed during it. So I rebooted and to my horror the tell tale signs of my card dying where there. Now I am running in safe mode, and I just requested a rma from evga. Hope it turns out well.

Best of luck to the rest of you,
-Rob

[PiLsY]

That's exactly what my card does if I have PEG link mode on any setting except disabled in bios. Identical screen. Does make me wonder (given the poor core oc and the yellow dots in ati tool at defaults speeds and below) whether my card is slightly faulty. It reminds me a lot of my 9800se which I couldn't use the disabled pipes on. You could run ati tool for hours on that and it wouldn't detect any errors, even though you couldn't actually see what it was rendering. Same issue here, the yellow dots don't apparently count as artifacts. Time will tell whether it needs an RMA.

Sorry about your card robbie, but check your motherboard bios settings before you send it back, even try a "load setup defaults". You've nothing to lose at this point :).

Matt.

[PiLsY]

HeavyH2O - Since I sorted the vreg heatsink it gets RED hot now - before it ran cool. It was only contacting the 2 banks of chips nearset the gpu, the outermost row was basically untouched. I used white gloop on the 2 rows nearest the gpu and built up the pads on the outside row using the pads removed from the others. They're a full 2mm lower, so each one basically has 3 of those pads on so I could get some decent contact/pressure. The temp of that black heatsink during 3dmark though is over 80c....

Matt.

[HeavyH20]

Well, atleast they are no longer broiling without a heatsink. I had a couple of cards that started showing the issues, then did the VREG heatsink fix and the problems went away. The chips are good to 150C, but, if the heatsink is at 80C you can only imagine what those components would hit without it.

[Garrett]

I don't really like the idea of anything in my case being 80c or over ;)

Couldn't you just stick a thin piece of copper between the sink and those 3 chips?
They lie lower as people say... that would make up for the height difference.

[GOESA]

Hey guys,

Now I have played with the card. and the performance is stunning for such a cheap card, my scores are in sig.

Anyone got any ideas for some improved scores? Use HeavyH20's bios + remove bios delta.?

I would like to know how can I check the voltage of the card to see whether it really increases and to control it doesn't go 2.1v or beyond...Thank you!

Does your mbm pick up the gpu ambient temp? With my 6800gs it did, but with the gto it only picks up the core not the ambient temp? Do I have to change any of the plug-ins or settings to get it to do this.

You need the flash utility, nvflash that is, and the GTX bios file.
Furthermore, you need to be sure that your card can handle the GTX memory speed, if it can't you can modify the GTX bios to lower memory frequencies.

You don't really gain anything from it, that card will not suddenly overclock better.

It's useful if you already had 1 GTX and want to run SLI :)

I'd rather flash the GTX down to a GTO though. May as well use the faster bios on both.

Hello guys... also I bought a MSI NX7900GTO T2D512E shortly after it was released. And it sames that my card is hardly overclockable, going on 700 core and 800 memory (1600) is totaly impossible . There are alot of artifacts in AtiTools as well in game, and it dosn't matter if im running it on the orginal bios or the GTX one.. I was testing a hour or two and the final results are crap, can't even go 670 / 700 artifact free!

So I did just down clock it to the standart clocking, and still I noticed artifacts in the newest FEAR +slowdowns after a longer gaming session... (However AtiTool dosn't dedect any after 15 minutes of testing, oh and it goes 77C!)

The most important question is, also I flashed it to GTX and then back to the orginal BIOS... can I still give the card back on warrenty? Or will they notice it? How does it work?

Software Description

As the name implies ATITool is an overclocking utility designed for ATI video cards. Design target is to write a light-weight application for the enthusiast - so no questionable registry tweaks.

Main Features

* No limits overclocking.
* Finding maximum core and memory overclock by rendering into a Direct3D window and scanning the output for visual artifacts.
* Temperature monitoring and fan speed control (on supported cards)
* Removal of Catalyst overclocking lock for 9000/9200/9550/9600 series.
* Artifact scanning mode for non-ATI cards - use together with a 3rd party overclocking utility.
* Loading a predefined clock profile on Application/Windows startup.
* Hotkeys that can be used any time to load clocks from a profile.
* 3D application detection (Direct3D 8, Direct3D 9, OpenGL) to overclock your video card only when required.
* Gamma control

I can see artifacts in games anyways... and when im giving lets say 680 core and 750 memory it dosn't even pass the initial test :>

[Xavior]

Darn it.. I exchanged my GTO because my secondary screen in dualview flickers.. It did like 830MHz on stock volts.

Now I got my new one.. And it barely does 740 with 2v. And stupid thing is, it flickers too.:( *sigh* Wasted my time..

[SF3D]

I just tested what my mem can do with voltage mod.

Results so far in 05 and 06 @ 710/1940MHz with default cooler

52486

:D Nice 1.1ns modules. What will they do with 2.15V< ?

[Xavior]

How many volts are you running through the memory?

I penciled the resistor, but couldn't get it below 820 Ohms.

Edit: Hmmz.. Did some more careful penciling.. Got it to 600 Ohms, lets see what happens.

[Alexandrus]

Be carefull, 600ohm it's going to be kinda low and the RAM will be overvolted.
2.00V is max voltage according to Samsung, and 1.90V is default.

[Xavior]

I know.. Didn't work out.

2.08V, max 740MHz. Disgusting, I want my old GTO back. :(:(

[Alexandrus]

2.08V and only 740MHz ?
Damn.....quite low. Are you sure you have BJ11 chips on your board ?

[Xavior]

Yup.. Took the cooler off, it's BJ11.

Nothing I can do about I'm afraid.. Wasting time going to the store and back multiple times.. Just to get a card that has lower overclocks and the same flickering.

Hmmz.. Don't know what to say.. Was playing the NFS Carbon demo, and suddenly, the screen artifacts and is stuck. Reboot, nothing. Having it exchanged again. :/ I hope they still have my old GTO.. It did 830MHz on standard voltage, and the flicker problem seems to be well known on the 7900 series.

[lwj5]

which is better 7900GTO or ASUS EN7950GT

[Alexandrus]

If you would read this topic you would know.
The GTO is in fact a GTX with lower voltage to the memory and lower memory clocks. 7950GT is a different thing. The GTO is faster and cheaper, and if you can mod it to give ~1.95V to memory you're going to have a full GTX for ~half the price. Not to mention the cooling, which is way better and quieter on the GTO.

[lwj5]

thx for your reply k i will get the GTO but the bad thing is it does not have High-Definition

Unpublished GPU appeared in [akiba] the reason which is always different (1/4)
Gale at Akihabara where the heavy rain attacks, the user which runs about busily was happened to see sporadically. As for their [me] applying GeForce 7900 GTO which is sold from Friday. Keyword is “GTO” “35 watts” “hybrid” “electric ornament nameplate”!
Like the piranha which crowds in the meat the people who search GeForce 7900 GTO

　Friday of the investigation day, receiving the influence of the tropical cyclone which changes from the typhoon, it became one Japan and China terrible heavy weather. Partly due to weekday, if normal traffic decreases extremely, but because in the same day the graphic card “NX7900GTO-T2D512E” of MSI is sold with each shop, the enthusiastic user which from morning flocks in [akiba] had enlivened the town.
og_akiba1008_001.jpg Gale because of the heavy rain, closing the shutter of the 1st floor, the [dosuparaakiba] store which has done business

　NX7900GTO-T2D512E is the graphic card of the PCI-Express x16 connection which loads the unpublished GPU of NVIDIA “GeForce 7900 GTO”. You say with the special model which commemorates the establishment 20th anniversary of MSI, according to rumor that only only 200 it arrives to the country.

　As for GeForce 7900 GTO core clock with 650MHz, memory clock 1.32GHz. The 512M byte we load DDR2 memory, the specifications other than the memory clock have become equal to GeForce 7900 GTX. As the reference card seeing, also the point where it has 2 DVI-I terminals of Dual-Link correspondence is the same.

　However, is a big difference in price. Vis-a-vis the GeForce 7900 GTX on-board card having arrived at approximately 70,000 Yen, as for NX7900GTO-T2D512E approximately 35,000 Yen of half price. When GPU of high-end class enters into the hand at price in the high middle, being, the enthusiastic user searching extremely small-numbered stock, [akiba] of the heavy rain it is the case that it had run about. With the [pasokonshiyotsupu] arc a little overplentiful stock was verified, but it sold out entirely while collecting materials of approximately 10 parts. After that the user which flocks was, but when sellout you understand, in [sugu] it kept going out in road surface of the rain.

　Itself it is not that much unusual for the unpublished GPU on-board card to appear from the GPU manufacturer. The graphic card vendor in order to finish to ship the tip/chip of the old generation to the front and back where the card which loads the next generation GPU is produced, acquiring new name to GPU where barely efficiency is not enough in proper specification, often uses the expedient which it utilizes. In regard to GeForce 7900 GTO, there was also a shop which you think that it appeared in the reason, but opinion of large crowd was different.

　The [pasokonshiyotsupu] arc “rare is the case very, but MSI commemorating establishment 20th anniversary, topic characteristic concern, in other words it seems that is produced with profit disregard. Still it is thought that from the fact that 7900 series release make grandly time of zenith, story is acquired to also NVIDIA” you say. In addition, from the certain shop “MSI the card of the special specification which at the major PC manufacturer OEM has been supplied, with quantity limitation don't you think? it seems that it circulates as the respective company brand. Because you hold down also the memory clock at BIOS level, you heard also the story that the hardware completely is the same expectation as the GeForce 7900 GTX on-board card”.

　For the user in addition with you can call the chance which is not, but the shop does not do the excessively good face. “Just topic characteristic being high, you can sell mono be too little. Not only there is no taste for the shop, is that the usual graphic card receives fanning. Honesty, selling out quickly, it goes out and thought now the shank” (the certain shop) with also grumble spills.

　Most shops had cleared at Friday point in time, but as for T-ZONE.PC DIY SHOP deciding number of sales of 1 days, from Saturday you sell in 3 days of Monday. Still chance is the case that it is





MSI shipped limited NX7900GTO-T2D512E with 1.1ns memory and very very incredible price - Because of commemorates the establishment 20th anniversary of MSI. I also recieve offer from MSI.

[RPGWiZaRD]

Can some1 do a quick favor, try launch FEAR or Oblivion with vsync disabled (meaning disabled from nvidia control panel too) so when you are in the menu for FEAR or Oblivion with a very high fps rate, if this is normal to all nvidia cards, you should have a high pitched electrical noise. Can you check that for me tho as that's what I've discovered with mine as it only appears when vsync is turned off and fps is like 1000+ fps (dunno exactly how high, might even be 2000+ :P) during menu in these games for example. Turning on vsync which limits the FPS rate in my case to 100 in the menus the noise is totally gone though.

RMA'd my first 7900GTO cuz of this even because I thought it was a faulty card with a bad capasistor somewhere but the 2nd card also had same problem so it seems like the high fps rate is the cause of it and I'd like to know if that's normal. But hey my 2nd card overclocks ~20MHz better on core and dunno about mem clock as I settled at 825MHz as I'm happy with it but Rivatuner's internal test still passed at 850MHz while with the old card it "only" passed up to 825. :)

BTW, XTreme-G 93.71 (http://www.tweaksrus.com/index.php?option=com_docman&task=doc_download&gid=778&Itemid=41/) drivers are really nice but even the official Nvidia 93.71 drivers are really great too, highly recommended. Best drivers so far I've tested both IQ and performance wise (best IQ but on par performance with some other drivers which has much worse IQ).

EDIT: setting prerender limit to 0 also seems to completely remove the noise as it slowed down the 2D performance and video clips rendering rate which was rendered at like 1000+ fps (which prolly is far from true but I'm just pointing to the rate FRAPS is showing) with the value set at "3" in Serious Sam 2 with vsync off and went to ~130 fps now with prerender limit set to "0". But 3D/ingame performance remains the same so that's good. Cards are getting too fast for some less demanding tasks these days, my previous 6800GT obviously was yet too slow but 7900GTO becoming too fast and putting some kind of physical limit on the card as far as how many frames it can render per sec without causing the card to whine. :p:

I tried those XTreme-G drivers and my screen went black after the install. Thankfully, though, I rebooted and got into Windows to uninstall and reinstall the 91.47s. With the XTreme-Gs, my screen color was all screwed over (like 8-bit or something) and the resolution was like 640x480.

Installing new drivers should always be done by using driver cleaner and first uninstall from add/remove and then go to safe mode and run driver cleaner and remove "Nvidia" drivers and then restart and install the new driver set. Otherwise some old settings from older drivers or when get mixed up with newer ones might interfere. That's my best guess what happened in your case.

I bought another msi for my friend and that made the same thing, no oc over 700/700. Now the question:
1)is it common?
2)do you suggest me to flash to gtx?Or this very poor results lower the possibility to achieve high frequencies?
3)can you provide a bios that has convenient timings but don't change name to GTX? Would that be useful for warranty issues?
4)I've read some topics about pencil mod...how can I measure resistance? The result of simply measuring the resistor shouldn't be correct, because I would have to care about equivalence of the whole circuit, or am I wrong?
Thank you!

please help me guys.

I used the same pads, I just had to remodel them to fit, and apparently it helped because my RAM can work at 800MHz w/o any extra voltage now :)

PS. Did anyone manage to make the card show up as GTX in Windows after modifying the original BIOS with the card ID as 7900GTX ? Because I did and even though the BIOS says GTX, the drivers still see it as GT/GTO.

these cards cost the same as normal GTX in australia....might as well call it GTX LOL!

What's the best MSI GTO original BIOS version ? And where to get it ?

Did anyone flashed a GTX bios ?

[Alexandrus]

Best BIOS for me by far is the original one, .39.09, modified with GTX clocks.

[jVIDIA]

Were can I get it ? ;)

And what did you noticied vs the original GTO .39.09 BIOS ?

[jVIDIA]

I know.. Didn't work out.

2.08V, max 740MHz. Disgusting, I want my old GTO back. :(:(

How do you test it ?

By the drivers Test button ? or benching and looking for artifacts ?

[Alexandrus]

Were can I get it ? ;)

And what did you noticied vs the original GTO .39.09 BIOS ?
Where can you get what ?
The 5.71.22.39.09 BIOS should be default for your GTO card. Or if you mean the modified version, PM me and I'll email it to you, I'm still testing it right now, for the past week.

Hi ! I have MSI NX7900GTO-T2D512E (flashed 7900GTX bios) 690/800 but my results are:
3DMark03 20100
3DMark05 9060

With the stock bios results were at 690/750 max stable
3DMark03 20600
3DMark05 9160

So looks like I gained nothing with 7900GTX bios but it doesent matter. I wonder:
Why do I get those results at the first time (stock bios) when your results are much much better.

PC I have : Gigabyte GA-K8NF-9-RH
AMD Athlon 3000 Venice 244x9 (2.20 MHz)
Kingston 512 cl 2.5 PC3200
Corsair 512 cl 2.5 PC3200
MSI GeForce 7900GTO (flashed GTX) 512MB 690/800
HDD WD 120 & 160 IDE 8MB
Samsung CD/RW & DVD/RW
Floppy Sony
Chieftec 420W
Modem Lucent 56K -----

P.S. I red something that it might be board like it has slower PCI-E. What do you think folks. Thanks in advance !!!

Your rather lowly clocked CPU might be the big bottleneck. ;)

Well thanks for the hint. It undoubtedly helped about 3dmark05 but for 3dmark03 not a bit. I'll see if it'll make any difference when I get ASUS A8N-E. Thanks anyway...... Regards from Balkan :)

[Alexandrus]

Actually, the GTO BIOS has tighter memory timmings, so that's why the lower clock with the stock BIOS, while the GTX BIOS allow for the RAM to go higher.

[electronpn]

The difference will be that the memory timings are slightly different, the GTO mainly uses more strict timings and therefore the memory is acting a bit quicker resulting in better performance but less able to overclock. So I found out that bios v.39.09 is better in overclocking....so I flashed it and I gets 690/810. My stock bios v39.15 is very poor one in overclocking. Who gets that bios let change to v.39.09. All that makes a little difference because main problem is CPU for sure. But when you start playing the game you had played before you got GTO, everything becomes immaterial. "So get your brain back to your game" :))))))))) Thanks a lot folks..............Regards from Balkan !!!

[jVIDIA]

With GTX bios I could only OC to 740 in mem ! But with the .09 GTO bios from Alexandrus I get 896 in autodetect !!!!! and can reach 960 w/artifacts !!!! INCREDIBLE ! :D

hi all, this is my first post here. been following this thread for a while tho so i decided to register so i can get some assistance :D. i got my GTO running at 722/1630 on stock everything. i would like to try the bios that Alexandrus modified. is it for the MSI or Evga model. i have the Evga model. thanks in advance! i really like the idea of getting the performance of a $400+ card after spending ~$250 :D

[Alexandrus]

It's for any GTO card, so if your stock BIOS can go as high as 1630MHz on RAM, go ahead and try it, but it won't make much difference I think, you already have quite nice locks for a stock GTO, especially on the core.

[SnipeR²]

ok no probs. where do i find the bios file? or ur gonna send that to me in a pm....

*EDIT*i found the bios u posted. it works really well. got a few mhz on the mem and on the core. what are the timings of the mem in ur bios?

[booZzter]

hmm.. i've read all the posts, but still dont have a clear mind on this matter:
is flashing bios is enough to set mem voltage as on GTX cards, or do i have to voltmod anyway???

[higgins]

you have to voltmod to change the voltage.

[booZzter]

thanx higgins)
so only good from flashing bios is using it as SLI with other GTX?

Has anyone used johnnyliu3377`s bios (the one coolaler used to flash to GTX).
He got good results with it. How is it different to stock bios?

[Alexandrus]

If you read the topic you will find out. GTX has different memory timmings.

Yes, I use it, it's the same as any other 7900GTX bios though

The reason ur maxing out at 722 is that at that point the geometric core clock is clocked @ 769mhz (stock Bios, delta 50). next step (core 723) will push the geometric core to "jump" to 780+ mhz.

If you want to get a better core clock you could try a bios with less delta. My cards (have 2) both max out the geometric core around ~775 and the shader core around 765 with vcore 1.65V.

Try a delta 0 bios and find your max shader clock, then change the delta settings so you max out both shader and geometric core. This way you gain the most from your card.

As for the memory clock, its not that bad for a stock cooler. If you want to clock it higher just do one of the Vmem mods, Ive tried both and they seems to work just fine. Memory also seem to scale really good with voltage. One of my card max out @ 880 with 1.98V and the other @ 845 same volt.

[SnipeR²]

how do i find the max on the geometric & shader core? or can i just use ur bios?

[zeeke]

Well, since you hit that 722 wall Id say that you already know the max of your geometric core (769-something), now you just need to try a delta 0 bios and see where the shader core max is.

Just DL nibitor and edit your own bios with that. If you want to check the current clocks of your cores theres a analysis tool in RivaTuner.

Id give you my bios but I have the MSI 7900GTO and Im not sure it will work with your brand of card.

[SnipeR²]

yep it'll work. the bios im running right now is from an msi card. got it from Alexandrous.

[jVIDIA]

Same here and it rules :clap:

[Alexandrus]

The BIOS has no Delta and it clocks very well so far, no performance drops due to lack of delta, if only I could make it to display GTX instead of GT/GTO in Windows ;)

[SnipeR²]

so that means im already running maxed out then? cuz im using ur bios as well. also, the day u get it to display as GTX could u sent it to me plz? :D thanks....
