Thought I'd start a thread on this to log how far it get. Especially as it's likely to go up if I get a waterblock and when the EVGA voltage tuner is released.

Also anyone else with the card (namely Swale at the moment) post your results in here so we can gauge what sort of level is attainable.

Just tested:

Core: 648MHz

Shader: 1397MHz (linked)

Memory: 1075MHz

Fan Speed: 100% (hurricane)

Temp Peak: 62 degrees

5 mins of torture on ATITool with no artifacts... However I still get a little bit of squeal... Hmmmage.
 
Ok onwards and upwards:

Core: 704MHz

Shader: 1518MHz (linked)

Memory: 1103MHz

Fan Speed: 100% (hurricane)

Temp Peak: 66 degrees

This is already higher than a lot can high from what I can gather so I'm pretty chuffed.
 
mine is currently stable @ 680/1380/1100mhz aybe could squeeze a couple of extra mhz but this is about comfartable for 24/7 relaible usage fan is on auto/idle 30%

100% fan surely not for 24/7!!!!!

No man, for benching.. Wanna see how far the card will go on air..

Latest testing:

Core: 704MHz

Shader: 1518MHz (linked)

Memory: 1151MHz

Fan Speed: 100% (hurricane)

Temp Peak: 65 degrees

Just memory this time to see if that would peak out which it hasn't yet. Screenie attached.

Ok so last one for tonight...

Shame it doesn't work so well in 3DMark06... All others I believe it spanks, especially Vantage, just sadly not 06.

Anyway the last posts tests were the card at pretty much its limit. It doesn't just start to artifact either, it BSODs. Same as a run of 3DMark... It doesn't crash out, it BSODs. Serious PITA.

Core: 707MHz (from 576MHz stock)

Shaders: 1551MHz (from 1242MHz stock)

Memory: 1151MHz (from 999MHz stock)

3DMark06 20419 which is less than I had with my X2 by about 900....

Ahhh well more voltage may help that.

I run my Evga GTX295's (Quad SLI) @ Core 745, mem 1205 and Shader 1525

With Higher voltage on the cores from 1.04v to 1.25v
 
I just got my evga GTX295, currently running atstock speeds. I'm ready to turn it up. Please post your clock/mem speeds and temps, and what stress tests you ran to confirm it's stable, like 3dMark06. I have XP.

cpu is q9650.

Thanks
 
I only have one gtx295. Did I need to do anything to tell it to run in SLI? Also, I'm using the precision tool to change the clock speeds, but they don't stay, meaning they go back to stock on a reboot. Do I have to run that tool at start up and load the custom settings everything time I reboot? Not sure what you mean by the voltage cores, but I use the evga gvt tool and the max is 1188mv. Do you mean you set yours at 1040? What abount any voltage changes in your bios related to your video card?

Thanks
 
it's it normal that the clocks speeds and voltages disapear after reboot, that's safety.

When you use Evga Voltage control, i can give you a tweak, so you can go instead of max 1.188v to 2.000v if you like?

Then you can go extreme on your Evga GTX295.

Aply this patch on your Executeble of Evga GVT in your map "program files" on your hard disk, and you can go to 2.000v max.

Evga GVT Patch uploaded by Croimans

have fun with it.

When you have Evga GVT, and you have this patch,

you are also able to adjust voltage of other NON-Evga GTX295's.

And to enable SLI, just simply enable SLI in nVidia configuration, that's it.

You can also disable SLI with a single vga, but then you have only the halve of the vga's power lol.

And my GTX295's runs @ 1.25v
