GeForce 260 GTX / 280 GTX Overclocking Thread

[roedzzz]

This my POV 260 GTX on stock cooling..

[Waxking1]

Card: eVGA GeForce 260 GTX
Cooling: Stock with side 120MM fan, stock thermal paste
vGPU: Stock
vMem: Stock
GPU: 756Mhz
Memory: 1269Mhz
Shader: 1512Mhz
PSU: OCZ PowerStream 520W

This is interesting. It appears that 1512 stable on the shaders is the limiting factor of these cards. It also appears that cooling the chip further doesn't allow you to run the shaders faster.

So unless someone has a really exceptional chip it appears likely that the limits to this card is 756/1512 stable. I'm sure the core could go faster but is limited by the shaders.

You are correct, with 1566Mhz shader card craps out after 2 seconds but I still managed to run 3DMark06 before just like in post #2. We need to change the ratio of core to shader in BIOS .

If anyone figures this out please share.......i might go ahead and try to mod the bios but im real busy opening my store....if anyone does it let us know.

Here is my max linked core / shader clocks one notch higher on the core and instant artifacts - still playing with memory.

, 1566Mhz is nothing to sneeze at . Were you able to do the same shader with stock cooler before or you did not try?

[BenchZowner]

As far as I know you cannot change the core/shaders ratio, sorry guys.
I've just modded my best GTX 280 and I'm preparing the other components for a LN2 session this Wednesday.

I got it from someone here was doing 702/1458, never tried higher on air.

I can run at 1566 but it is not totally stable. I did finish a 3D06 at 1566 but my 1512 shader did better because when I ran 3D06 at 1566 I saw artifacts a couple of times during the test. If you ever see artifacts while running a test it will kill the results.

I have the stock cooler but I have used AS5 on the spreader. Once you get to 1566 on the shader, if you want to increase the core past 756, you have to jump to something around 780. With my cooling I am not stable at all at that speed, so the best I could do was 756/1566, but not stable.

I have a feeling 756 will be the max 99% of them can do stable.

I think you are right about that. On the other had I just got a 280SC and I think it may run clock a little faster than my 260. The trouble is that it overheats too quickly and I don't have water. I'm going to order an aftermarket cooler as soon as they start selling them(thermaright). The memory on the 280 will run at 1400 until it gets up to the mid 70s temp and then starts artifacting. Also the shaders will run at 1566 until the heat gets higher. Not sure about the core yet as it seems to max out in the 730s but here again I hope some cooler temps will help this also.

Since ATI cards have so many issues i decided to go with Nvidia, again. The cheapest GTX 260 is EVGA GEFORCE GTX260 for 244 euro and the chaepest GTX 280 is GAINWARD 9351 GTX280 1GB or XFX GEFORCE GTX280 1GB GX-280N-ZDF for 390 euro. Do u think the extra 150 euro worth it, either they both run overclocked or not.

I can also get XFX GEFORCE GTX260 896MB XXX for 295 euro. Count this option in too.

Take one very eager 260GTX and strap one crazy E8400 Rocket to it's ass and let them go.
you won't be disappointed!!!

This combination just keeps getting faster and faster!!





It's very hot here now but winter is coming!!!

My Card is the MSI although I believe them all to be quite great.

hmm my 280 with ref cooler and modified memory timings in bios.

http://www.techpowerup.com/gpuz/nhu6u/

735 core, 1512 shader, 2700 memory.

no matter how much more i loosen timings wont go next step up on memory, needs more voltage. it's stable for gaming all day long and benchmark thrashing at those clocks.

just ordered two EVGA 280GTX from newegg
i intend to kill my games with SLI setup

[pcaddict]

little bit offtopic,but should I upgrade my 7950gx2 to gtx 260? cuz I need new graphics card and gtx 260 looks nice..

Could gtx260 handle SkethUp, photoshop and other stuff like that smoothly? (and of course some games like crysis, bf2142)

[Kondik]

Photoshop is CPU and Memory based
And for gaming of course It will handle them.

[pcaddict]

okay, Bfg gtx260 is coming in few days

[BenchZowner]

I'm ready

[cantankerous]

oh sweet. Loving the thermalright on the shader chip!

[pcaddict]

that looks cool

[Mango31]

Finally... after a 2 month odyssey the RMA 280 arrived. And it clocks excellent - happy camper over here

[Kondik]

I hate you for those clocks , I really do !
GPU-Z Temps please ?

[Waxking1]

Very nice clocks Mango. Temps look to be 50 degrees to me. Has to be watercooled. I would like to see a 3DM06 score just for comparison. And what happens when you clock your core to 783?

Holy memory , you lucky bastard .
