added xxdozer32, and it's stock voltage i assume if not correct me ^^
yes sir. ive OCed to 940 on 1075mv and ran kombuster on it, did pretty damn good, max temp was 59c and max fps was 72 at a res of 1680x1050
oh my bad, stock clocks are 700 core , 1400 shader, and 1840 mem on stock voltage, that 830 OC was on stock voltage (962mV)
Getting my Gigabyte GTX 460 768MB today!
For only 54 euros
Count me in for SLI.
Very very nice. Let me know if you want a bios cooked up.
Does this stable, 4 hours furmark max temp 80 degrees Celsius.
I'm thinking about lowering 2D voltage and maybe reapply thermal paste on CPU core.
Offer still stands. Upload a bios here in ZIP and I'll have a crack at it.
Thanks mate. I uploaded my BIOS.
4 hour Furmark screenie @ 840/938/1680
Seems that fan speed can't go lower than 40%, even when fan speed values are changed in the BIOS, going below 40% shows a very high RPM value in GPU-Z.
I changed my 2D voltage to 0.75v but apparently the voltage regulator on Gigabyte GTX 460 768MB OC version can't go below 0.825v, that's what GPU-z shows.
Try out the attached.
Lowered min fan speed, lowered 2d voltage, uncapped max voltage to 1.15v, updated 3d clocks to ones you provided.
Could you tell me what min fan speed and 2d voltage? also why would I need 1.15v for the GPU? I can't use software voltage control.... my card isn't supported AFAIK.
20% fan speed and .75v as you posted.
Just to have the option. I didn't adjust 3d voltage at all. Maybe nVidia Inspector would allow it.
thanks, but at 20% the fans don't spin up at all, could you change it to 35%?
I made a new bios, 0.725v for 2D and 0.85v for ''setting 1''
Don't know how to change fan speed.
AFAIK they only go up 10% at a time. Using nibitor 6.02 go into temps tab on the bottom right. I'm afk right now posting from the 'droid.
Nvm i found this great tutorial : http://forums.guru3d.com/showthread.php?t=336117
Found out that fermi voltage regulator can't go below 0.825v so it doesn't matter if you go lower than that because 0.825v is always used as the minimum voltage.
Also if you change the shader speed than you must change something called ''bumped shader speed''
For all people who have a Gigabyte GTX 460 768MB OC, if you change your fan speed to 20%, your fans will stop spinning, if you set your fan speed between 20 and 33% GPU-z and other programs will report a faulty fan speed rotation (RPM), if I set my card at 30% GPU-z shows 6000RPM, which isn't correct. But if you set your fan speed at 34% GPU-z shows a correct RPM value, in my case 1290RPM, that's lower than stock 1640 RPM (40%).
My bios settings are:
min fan speed 34%, max 100%
2D and low 3D performance @ 0.825v, performance 3D @ 0.987v stock voltage .
Max voltage 1.15v
Thanks for your help.
mudkip i have added u to the list, i hope u don't mind that ^^;
just noticed that my GTX 460 SE has been running for 800/4000 for more than a year now D:
hope it lasts longer
oh wait, i think ive lowered my mem clocks to around ~3900
not seeing much improvement, same with the core/shader clocks. It can go 850/4000 without changing the voltage but the improvement seems minimal (unlike when i clocked it from 648 to 800). Im only using a 1280 x 1024 display anyway D:
furmark 20 min stable:
855/1710/1025 (GPU/Shaders/Mem) @ 0.987v (stock)
Can't go 860 without raising voltage
My card does 840-850/1000 (GPU/MEM) bf3 stable @ 0.9875v stock, tried to overclock it a bit higher and it does 860 Core @ 1.025v and 870 @ 1.0625v, should I leave it at 860 core?
Sorry. Clock her up to 860.
Yup. There's pribly only y going to be at Max 3c difference but your gpu clock outweighs rise of temps from a performance perspective.
Does a newer 560 TI count??? LOL
