Has anyone tried increasing PCI-E a bit? (ex 105)
any one know is it safe to flash say a stock pny bios to an xfx oc'd bios??

how do you flash it ?
well i got a litle time extra work and i push a litle more for memory and 1700MHZ with no problems , stokcooler and memory Naked:

Club3D 7900GT
450 @ 1320 --> 580 @ 1720
No mods and stock cooler.
10K is almost too easy.
Attachment 44791
450/1320 to 580/1720, damn nice man
Club3d cards are that good?...DAMN
So on average we can expect 570-580 overclcok on the core and about 1650-1750 to the memory for the 7900 GT. Its not bad at all but than you can't touch the 7900GTX clocks...
That's stock cooling, stock voltage...
With a few volt mods and better cooling you could probably catch the GTX.
what drivers you guys use 83.90 or 84.20???

XFX 7900Gt Cards with 1.2ns memorys?????
http://www.bjorn3d.com/theforum/view...ca67f5a79971b9Quote:
All tests were performed with a 1280x1024 resolution. The cards tested claimed 1.2ns DDR3 for both cards. ForceWare 84.12 was used for testing.
maybe this is explain why XFX 7900GT cards get easly 1800MHZ or more with no problems and others 7900GT only get 1700/1720Mhz :woot:
I was surprised when i put 1800MHZ in the collbits and pass with no prblems and benchmark with no artifacts , nothing :D .
Coolbites only let go till 1800Mhz how i put more than 1800Mhz ????
You are SO close to 10k. Come on sir, make that extra little 5mhz on the core, and hit 10k in 3dmark05, you will feel miles better for it.Quote:

Gahh I guess I better aim for 11,000 now that 10,000 was broken so easy.
Dazog 11000 its my point too , when rivaturner come out ( twaeks ;) ) and when vmod bios work .
Dont forget that this is 10K Stokkcooler , Naked rams , stok bios , No Tweaks ;)
we have all this to use yet :banana: :banana:
mascaras can you check personaly that your XFX has some 1,2ns memory?
Just look at the chips and see what they say
XXXXXX12 would be 1,2ns and XXXXX14 will be 1,4ns quite easy
the second line in the row...

It's overclocked at stock so it's very well possible that they editted the timings. This is easy to test as their bios works on all 7900GT's ;)Quote:

Yes, but we are talking about the XFX 7900GT's, which reach higher memclockes than other 7900GT's.Quote:

yep , i was thinking in ppl who have 7900GTs not of XFX try to flash with XFX 7900GTs bios to get higher memory cloks , no???
woah
you can do that??
put 7900gtx bios on 7900gt only use half the onboard dram? (btw if you look at various reviews, teh 7900gt looses a lot of ground to 1800xt/7800gtx512/x1900/7900gtx in most benchmarks at 2048x1536 4aa/16af... 7900gt *only* 256mb, fine for all lower settings ofcourse ;)
I dont suppose any of you guys has splinter cell:chaos theorty and could do the default timedemo
That would work just fine with the "-4 -5 -6" command to force the flash.Quote:

So far I can't get over,
545Mhz core
808Mhz memory
even 1 Mhz more on either will lock up any 3d program.
3DMark05 kicked out a 9538, I can live with that for now. It's still early on, but to me I can't honestly say that the XFX is the screaming deal. Especially if you can't tell which memory you are getting. Hopefully will get to see some others posting results with this card.
Off to read about this Samsung memory....maybe try the pencil mod for Vmem and see if this memory responds.
EDIT: Oh yeah using 83.91 Win64 driver.
Sweet, I have the highest single 7900GT score.... for a very very very short of timeQuote:

Good to know. Yours at "stock" faster then mine can go overclocked. Hmmm. I doubt they binned these but who knows. Maybe I'm the X factor :( LOLQuote:

Maybe 1.4ns and 1.1ns chips are made on same production line ? And those just felt through quality tests but aren`t that bad to be marked as 1.1 :D
just my guess

Strange. No BJ14 in Samsung website. But BJ is surely better series of GDDR3 chips. And as you see it has +0.2V on them. Can you guys check through BIOS what Vmem is on your cards ?
Oh found explanation
http://img119.imageshack.us/img119/9136/explain7na.jpg
Looks like this lucky card has those old BJ14 onboard

Dazog what memory is on your card ? And what manufacturer ?

To me that means you would have fewer 512Mbit chips for 256MB cards then with the 256Mbit density 256MB cards? Can't be right...the pictures I have seen of BJ14 256MB cards have 8 chips same as any other GT
I just got in a BFG 7900gt OC.
Stock cooling (no air flow over mem either) yeilded 550x850. I do not know the mem manf or specs. I will be pulling the card tomorrow (hopefully), to install a waterblock and some better cooling for the ram and will check then.
Sadly my San Diego crapped out and so I'm using a ****y 3000+ Winny at 9x215 :brick: But still managed to reach 18.5k in 3dmark03 and 9k in 3dmark05. Gonna need to replace the cpu soon.
Btw, my coolbits maxes out at 819mhz on the mem...but I've seen others with GTs allowed higher with that app. Is there anyway to up the maximum value?
Use Rivatuner.
These 1.4 ns chips are just INSANE.
I'm sure everybody would be using Rivatuner - but, it doesn't support 7900's... yet.
Yeah, I think I concured that BJ14 or BJ11 are just bins from same production run. Re-thinking, I realize they can't be same chips. BJ11 are 512Mb, BJ14 are 256Mb (both GT and GTX have 8 chips each). I think the naming is just coincidence. Samsung probably made some "BJ14" early on, but since good yields, removed it from the list. Afterall, is anyone with 2.0V not hiting 1600 (800Mhz)?
EDIT: I'm out of luck on the pagecomputer PNY 7900GT = $270 deal.. OOS and cancel.
Ah, darn the new RT 15.9 isn't out yet.
These cards are incredible. I will try to break 11K with stock cooling and without any mods :D
I payed only 339 € from this performance.

try 84.20 and see ig you can get higher cloks , i had same problem with 83.90 but 84.12 and 84.20 its OK
btw: Codeman coolbites go Max to 900 , maybe you have a old version
EDIT: sory guys my fault i saw badly in dark last night the chips are BC14 not BJ14:
K4J55323QG-BC14
Haha :) After researching the BJ-14 on Samsung website and looking in your other thread about "7900GT clocks" I was zooming the picture of your card, and thinking that can't be a "J" but it was so blurry I couldn't be sure.Quote:
EDIT: sory guuys my fault i saw badly last night in dark the chips are BC14 not BJ14:
I'll search around for 84 drivers, maybe that will make the difference. Hopefully there is a x64 flavor.
yeh , i already said to you that 83.90 freezes and loks PC , and also when push the Test Clocks in coolbits its freezes and even when dont freezes the 3dmark 2005 dont run the image turn all black and freezes the PC and also only the drivers since 84.12 reads the temperature right, the others drivers read +- 10c than the real temp:
83.90 ----- 47c ( and freezes when change cloks )
84.12------ 37c (no problems)
84.20------- 37c ( no problems)
Its possible, the download said it was released in '04, however I have not found anything newer. You happen to know anywhere to get the latest?Quote:

Friends, coolbits is only a registry key (.reg) that enables the OC section in the nVIDIA software/driver. The one's from ATI (Catalyst) have this feature always on.
So the 900MHz limitation is not implemented by coolbits as you said, but it's a nVIDIA software/driver limitation.

if that is the case, we can edit the bios to a higher clock and then coolbits would allow to go even higher.
That would make senseQuote:

i agree with pandora , maybe it depends on default cloks
Pandora see with Nibitor what is The geometric delta on your XXX card
It for sure does. The max allowed clock is bios clock multiplied by some number like 1.25 or something along those lines.Quote:
i agree with pandora , maybe it depends on default cloks
Why not just use Powerstrip? It allows overclocks of any mhz amount you want on my 7800GT, I bet it does the same for a 7900GT.
I will be getting a 7900GT in the next few weeks and was wondering the same thing, is powerstrip the best OC utility? I used coolbits and riva tuner before.
1) Vendor : Point of view 7900 GTX
2) Stock speed : 650/800
3) Overclocked speed :728/938
4) STANDARD COOLING , using powerstrip think i got a nice card here :)

I bet its the Delta's stopping us from getting high scores at 600/1800 I expected close to 6000 in 3dmark 06 and only got 5555
So I dunno, Hopefully the next nibitor can tell us all we need to know about these cards on a bios level.
coolbits's max clocks is a registry key, which can be altered..
now where was that url :rolleyes:
/edit
that should do it..Quote:
Jian,
Check your registry these are the keys and values that coolbits uses for hardware options, Marge enables overclocking and Bart, Homer and Krusty set the range of the sliders, this is a copy from my registry, these values are probably going to be too hot for your card as I am running an Ultra, but these Dword values will give you core settings from 220-315 and memory from 410-575....
REGEDIT4
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Servic es\Class\Display\0000\NVidia\NVTweak\Hardware]
"Homer"=dword:000037b3
"Bart"=dword:55172098
"Marge"=dword:00000001
"Krusty"=dword:55172098

Hey I found this file for an easy way to supposedly alter the range of your sliders also:

Just got my XFX 7900gt extreme today. Stock clocks are the 520/1500. Coolbits auto detect of 542/1600. Put it under my watercooling and even though temps are only 30C idle and just slightly higher under load, coolbits still detects the same clocks.
Manually clocked it to 545/1700 with no artifacts so far. Still working on it, but will wait until Monday when my new Opteron 146 shows up to test much more.
ah, wc, makes more sense. nice clocks.Quote:

Excelent core OC men !
Some question for you :
Are you using coolbits 2 ?
Have you changed anything in the registry ?
And what driver are you using ?
What is the max. core / mem that passes coolbits test ?
For those speed's you are using Powerstrip right ?
I am using ATItools the new one.. max in coolbits is 560/900 i think it was.. but the core went to 610 :D with slight artifacts though, or actually i don't know if it was the memory or the core that artifacted..
/Grau
http://www.tweaksrus.com/index.php?o...=433&Itemid=43

very unlikelyQuote:

Every +0.1V should give 50-100Mhz more. If he had really fixed the overvolt problem (and he has a good core), it would be more like 713Mhz+ ;)
I think nVidia was afraid of repeat of GF4Ti 4200 -> 4600+
EDIT: Can anyone with 7900GTX run some 3dMark2005/2006 standard, but at 7900GT clocks (or anyone have link where its been done)

Indeed nothing godly @ 613/1786, if stock can run at 560, it bu far will run @ 613 with any good cooling , like chiller or dod
What is actualy stuning me is taht my 520/1500 XFX bench 06 @ 550/1804 stock :/ with no artifact, am considering a bug in clocking

oh and btw..
84.21 official whql are out:
http://www.nvidia.com/object/winxp_2k_84.21.html
and...
84.20 from tweakrus:
For a driver to perform this well, you'd expect IQ that looks like it's been beaten with an ugly-stick. That's definitely not the case here. The stock driver doesn't deliver the breathtaking image quality of 84.12, in fact it suffers from garish colours and poorer texture detail, but I'm being picky. Enter 84.20 v2... As I said, the performance tweaks didn't do that much for this driver. Image quality is a totally different story though. Textures are much sharper than the stock version, and colours look much better. IMHO, IQ still isn't quite as good as 84.12 v2, but it's got some of the best visuals I've seen lately.http://www.tweaksrus.com/index.php?o...=433&Itemid=43
for me 84.20 its better than 84.12
