How does one overclock a GTX260?

[craptakular]

As title, where does one start? I want a little more juice for bc2.

Download MSI Afterburner and start from there. You could probably get to 700mhz on the core and 1200mhz on the mem but if that's unstable when gaming, work backwards and clock down. Personally I have the core and shaders unlinked.

I did find that overclocking my GTX260 crashed BC2 quite often with driver errors but hopefully you'll have better luck.

Yeah they clock pretty well. Watch teh temps though.

I'm using rivatuner and have just got GPUclock=756/mem=1100/shader=1512

I ran furmark for about 15 mins and max temp was 61C, with 60% fan speed.

That good? Is it faster than a GTX280?

i use evga precision on my inno3d, then once happy with the settings i flashed the bios using nflash & wrote the bios using nivitor. this allowes the fan settings to be adjusted & more aggresive. i havnt increased the stock voltage didnt seem to make any difference. final settings for gaming are:

core,shader,clock 692,1492,1202 on a 192 card. for crunching seti i clock further using evga precicion to a shader speed of 1575. any more she starts to give problems.

but she does get hot hot hot! so really need to up the fan speed early.

Is your card a 260 216 core? If so that's a very good clock...and yes it's quicker than a stock 280

Yeh it's a 216, it's also a Gainward overclocked model I think because it has a dual 120 mm fan design.

I will try upping the memory tommorrow once I know the gpu and shader are stable.

I also put mx-3 on the gpu, maybe that helped?

What's the rest of your setup?

 

[craptakular]

AMD 965 @ 3.8ghz, 4GB DDR3 ram, samsung F3, win7 64bit

 

[gurusan]

ah ok. Just making sure you have a clocked quad as the game like CPU power.

At what res do you game? My 260 struggles with BC2 at 2048x1152 though it is quite playable...so I've bought another one for SLI

~660/1458 core/shaders will match a stock GTX280 give or take so that clock should put up as good or better performance.

Most GTX260 manage a max stable shader overclock of either 1458 and 1512, very few will do a core clock beyond 730-740 tho with complete stability. The gigabyte SoC and sparkle dual fan cards tho seem to hit upto 760/1570 with complete stability.

Might want to do some benchmarking tho as I've found that certain core and shader clocks seem to run faster or slower than others i.e. 720 core 1440 shader with 1200 memory seems to be the sweet spot for most of my cards not sure why unless they have some kinda strap relationship like the northbridge/fsb on some motherboards.

I GAME AT 1920 X 1200 so the overclock is really noticable, so much so I can run the game on HIGH without noticing any lag.

I'll try your settings as suggested. I have a gainward dual fan design so maybe thats why it clocks well?
