MSI NX7900GTO T2D512E is 7900GTX?!

[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 ?

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.

[Goofisch]

I have a msi 7900GTO in order.. will it work @ 100% with a amd 3000+ clocked @ 2.7ghz and Gskill pc4400le @ 300mhz? i,m affraid if the cpu will bottleneck the videocard...

I've tried penciling that left resistor (1k ohm standard)
Brought it down to 849 ohm and got 1.95vdimm instead of my default 1.81v

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...

[vyper]

Thanks Garrett for the clear pics and results.

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.

Doh!

So do we need to loosen timings when we up the voltage and clock?

[Garrett]

Hahahahaaaa.... YES! 12k single card... DONE!

With the core unmodded (1.4v) @ 715 and the memory @ 1.95v @ 1810Mhz
And by the way, I saw NO artifacts :thumbsup:
I haven't changed the timings of the memory

No it's not an approved driver, but I don't care much for that

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

Mine start artefacting @ 840 (837 exactly)

[Garrett]

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 03
3Dmark 05

It seems that the slow cpu has more effect on 05 3Dmark than on the 03.

I assume you mean what pencil, right? It's the 8B version
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
Yeah I really dig the price of this card, 242 euros
I remember last year November when a 7800GTX 512 was still 749 euros
Look what you get for 1/3 of that price now

[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.

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?

must I pencil both resistors or just one of them???

[Rubiconx3]

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.

My evga 7900GTO does that.. but only one way. In some program called "Stability tester" in games i dont hear anything. Maybe i should RMA just to be certain

[Nosfer@tu]

#120 I will bet you it is driver related.

I have had the same issue....

Remove and install again. Use 92.91 And not the 92.4 that is WHQL.. I had problems when tabbing in and out of source
