GeForce 260 GTX / 280 GTX Overclocking Thread

[icecpu]

I got an EVGA GTX 260 Core 216 today. So I am guessing around 700 mhz on the core and 1100 on the memory is acceptable expectation ? I am still enjoying it at STOCK but soon I shall torture that baby. It is scoring 60% more 3d marks @ stock than my old 8800GTS 640mb overclocked.

please post some 3dmark 06, stock and overclock

I have updates guys. I turned off the PhysX from the drivers. The greatest news is that it is all about the shaders on this card. I had my shaders at 1516 and I thought it was stable but my GPU would not overclock past 700 with those shaders and it would not even pass 1 run of 3D mark - greatly unstable to overclock past 650mhz on the core with shaders > 1500. Than I lowered them to 1458 and that gave me headroom to push the GPU to 730mhz. I have ran 3D mark Vantage a few times with absolutely no artifacts or hiccups. This is not the maximum overclock of the card. I have yet to see where is the limit of the memory and the GPU with those new shaders speed. So given those discoveries i have ran vantage a few times at 730/2430 with PhysX disabled(many ATI people don't like the results with PhysX so I had to disable it):




ps: I have very important update. There is some really weird stuff going on with the shaders. Before i was trying to do vantage on 700 core and shaders of 1512 but i had absolutely no chance in completing even 1 run, the whole thing was going black screen 2 minutes in the run. After I saw Dejan's post about the shaders and the core clocks I decided to skip the range between 700 and 730 with 1512 shaders and jump directly to 756 mhz. Surprisingly it passed vantage with absolutely no problems or artifacts. So the moral of the story is to NOT set up high shader values and than force core clock of anything less than 730... Here are the new scores:




ps2: Ok guys i played around and the final values are 756 core/1512 shader/1224 memory. For core speed higher than 756 i need higher shade speed than 1512 - EVGA precision does not let me set a higher value than 756 with 1512 shaders, so i try to turn up the shaders but the next option is 1566 which is not stable. The maximum is somewhere between 1512 and 1566 and for that i would need RIVA TUNER but don't want to install it now... Nonetheless, that would give me like 10-20 mhz max which is not significant since the memory is maxed at 1224. here are the final results:

I hope they fix G200 lackluster OC'ing ability in coming revisions & process'.
It's pretty sad that a slightly OC'ed G92 can easily beat the shader performance of a stock G200-100 (GTX260) and a voltmodded G92 matches G200-100 watercooled/vmodded.

Hey largon why don't you post up links to these G92 cards that leave the 260GTX in their wake. I have not seen them.

1262. 3Dmark 2005 - 20281 marks - largon (Team Finland) - (GeForce 8800 GTS 32... @ 756/1107mhz on h2o)

1669. 3Dmark 2006 - 13632 marks - largon (Team Finland) - (GeForce 8800 GTS 32... @ 729/1152mhz on h2o)

I can't find where you even own one.

So keep on trolling.

PS. my scores with a Stock cooled 8800GTS 320 absolutley crush your H2O cooled one. Perhaps you better just concentrate on your equipment.

[largon]

WeldZilla,
Firstly, for your information, those are not G92s, they're age-old G80s. 320MB RAM hello?
And secondly, I'm not interested in 3DMark. It's a CPU benchmark.
Third, I haven't updated my HWBot in, what, a year now?
Fourth point, read my post. Here, let me quote myself:

It's pretty sad that a slightly OC'ed G92 can easily beat the shader performance of a stock G200-100 (GTX260) and a voltmodded G92 matches G200-100 watercooled/vmodded.

My current G92-400 (GTS) with benchable shader core @ 2.43GHz (= 622GFLOPS) beats a stock G200-100 (= 497GFLOPS, ~600GFLOPS if MUL works about 40% of time) by 25%.
^ my 1st claim -> □

Once you watercool/vmod (of which latter doesn't gain anything) & OC a G200-100 to maximum you might reach some 1.574GHz shader core (604GFLOPS, ~725GFLOPS if MUL works... 40%).
^ my 2nd claim -> □

And those are just my results. I'm sure there are better ones out there.
Was there something else?

PS.
And, as an interesting detail, none of the G200s in this thread can match in texture fillrate against a G92...

[WeldZilla]

OK now post a benchmark as opposed to a stress test..

you know 3D03, 3D01SE, 3D05, Aqmk3, 3D06, hey even the Devil May Cry bench we have seen of late.

I will say that is a great furmark score. Nice temps too.

FINLAND pwn everythng! gtx260 is coming..

[WeldZilla]

I look forward to seeing you post up some results pcaddict!! sooooooon

Yesterday i recieved my two evga 280GTX cards , and the install them in SLI

the performance is very impress , i can play crysis and crysis warhead with ultra high setting and 16AF - 16AA very smooth without any lag

[laragirl83]

Final clocks...

[laragirl83]

Done some furher testing, then again, Furmark stable.

[Brahmzy]

That's exactly what I've settled on with my vanilla eVGA GTX260. Any higher and I get artifacting in Crysis. Fan speed on AUTO.

So, do ya think if I step up to a 260 216, I can get those same clocks? I'd hate to take a "step" backward. Ba da bump.

Hey guys, been working on my new build for some time and have got some results now. My GPU loop is pretty sick and consists of EK GTX280 FC with the LC ram back, DDC-2 w/Petra top, Feser Xchanger 120.3, 3x Sanyo Denki 120x38mm San Aces'.

I have an XFX GTX 280 Vanilla but am getting pretty impressive clocks out of it. Top so far is 792/1620/2664 Vantage stable.

Here is my Vantage result, but has PhysX driver enabled...

http://service.futuremark.com/compare?3dmv=413340

Will have more validation shortly, but seems pretty solid and I think I have more in the memoryclock department.

That's excellent, your card will probably benefit from extra vGPU, hello voltmod , congrats on good silicon.

I was thinking of Vmodding the card, but read that it has minimal gains and cooling is more of an issue. I think I have that covered

Also dont want to fry the card and have no warranty, I am eyeballing a QX9650 LOL, need to save my cash for that

Also want some Murdermod parts for my TJ-07

Thanks for the kind word nfm

Man thats the best GTX 280 overclock i have ever seen.

[BenchZowner]

I just RMA'd my dead GTX 280 ( the good one doing 771/1566/2808 on stock cooling & stock volts )

[turtletrax]

Man thats the best GTX 280 overclock i have ever seen.

Thanks, its all me

I am really glad I got a good GPU. I spent a fortune on cooling for it, so I am happy it was worth it

And sorry to hear of your dead card BenchZowner. Seems luck has not been on your side lately. I just wanted to say I really enjoy your hard work and hope your luck improves.

Edit: a few pics

[icecpu]

my card suck when it come to shader overclocking, stuck at 1402
At 1458 , ATItool artifacts right away, any ideas ??
fan @ 70 %


EDIT : Riva Tuner does not let me set any thing between 1402 and 1458

The SPs just like the GPU Core and the RAM can be overclocked in steps, not single MHz.
The steps for the SPs are 54MHz.

[dnottis]

Water cooled - running like this since I got it about 2 months now. Game stable, furmark, vantage, etc.



Don't hate

[bito]

largon.....have a look here at the texture fillrate............granted your G92 is excellent also.

[Carfax]

This is ridiculous. How come my GTX 260 is only stable up to 685 while everyone else is getting well into the 700s?

Are you guys running your cards with a BIOS volt mod?

[BenchZowner]

There's no BIOS volt mod for the GTX 260 & GTX 280 cards Carfax.

Why do you think my card is such a ty overclocker then? Is it just born that way?

I checked my voltage using Nibitor and it's at 1.12v for extra.

I might take off the heatsink today and see if it has any thermal paste on it.

C'mon guys, I need some help.. What do you think I should do? My temps hits 60c at 700mhz on 100% fan speed, so it's not like it's getting that hot.

There are good cards and bad cards. Overclocking-wise.
You might be lucky and pick a 730+ MHz GPU GTX 280 or a 680-690MHz max GPU.
So far I had 4 GTX 280s, one of them was benchable at GPU:771MHz/SPs:1566MHz... my second best now is a 753MHz/1512 card.

There's also another factor, stability.
Some believe that 1 hour of gaming is fully stable, others don't.

And of course...there's also the "lie" case.
Beneficial or not, some people tend to lie on such stuff for no apparent reason.
