Good Evening, I've been working on over clocking my computer as of late and I'm looking to over clock my graphics card. I'm currently using GPU-Z to make sure Memory clock, shader etc is what it states it is and MSI Afterburner for the actual over clock. Currently I've been playing with the Core clock / Shader Clock and moving the Memory Clock up. I was wondering if this is the correct procedure for over clocking a graphics card or do I need to change the voltage? Current Graphics card Over clock is: Default: 715/1430 Mem: 1800 Over clock: 830/1660 Mem: 2100 Current Voltage for both is: 1012 and unchanged. Fan Speed at 70
To make life easy for you I've got my 460's set up as follows: Core; 812 Shader: 1624 Memory: 1912. This is a good solid over clock on air, but as mine are water cooled I can push a bit higher. I think these are pretty similar numbers to what Bit-Tech got when over clocking their test card.
Download Asus GPU Tweak... and adjust and test from within the tool in windows until you find a stable overclock. Test it with a combination of 3dMark 11 and Heaven benchmark. What will be stable in one may crash in the other. I used this app to tweak my mates SLI'd 460s. Worked a treat.
http://www.bit-tech.net/hardware/graphics/2010/07/21/overclocking-nvidia-s-geforce-gtx-460/1 Voltage is used to stabilizes higher overclocks however it make the card run hotter as well as potentially damaging the card over time. Its not really advisable for day to day use basically.
It's got a bit more functionality bud and the next release will have the 'flash to bios' option once you've set your overclocks.... but obviously you need to ensure they're stable first.
played mafia 2 all the way through on a 460.. with everything up even the physx scam on air.. was at 906 clk, think the mem was at 2150 could do 847 stable stock volts.. the 906 was with a bios volt mod.. just good air, custom tim job and the stock cooler
