Looking to OC my GTX 460 to 900/1800

post #1 of 28
Thread Starter 
With out any voltage change, I can get my 4601gb to 800/1600. But im looking for a little bit more. I have MSI afterburner, but I don't know what the safe voltages are. Also, I am unsure about a safe temp range. Any help would be great! thanks


Here are some benchmarks!
Starting off with GTA 4, shockingly quite the improvement for a cpu intensive game!

Thats all i was able to get done last night. I hit 900mhz @ 1.087v and it ran furmark for 6 hours. But it crashed in the first run of Heaven, I dropped freq by 10mhz per failed run until it passed. Seems to be stable at 870/1740/4000 with 1.087v to the gpu. Temps are mid 70C with max fan.

Depends how you are going to rise volts.

Some progs have safe limits.

My 5850 can reach 1.5v, but Trixx wont let me get past 1.3

Mine is running at 18c now idle *not overclocked*
Then when it is overclocked it idle's at about 25-28c

EDIT: Sorry, i didn't answer your question. Safe temps for a normal 460 are anything up to 50-60c

you should be able to do 860 or so on stock voltage. 900 might not be possible even with a voltage bump.

The 460 is a pretty lenient card when it comes to voltages. Even stock max 1.087V is perfectly stable. Just get yourself a decent artifact test like OC Scanner, watch your temps, and clock away.

Is it really 50-60c? Because it hits 72C at stock clocks and voltage and it has the nice cooler from gigabyte.... Sad face

Where'd you get that? They can pretty much go up to 100C. Heck, mine cracks 73-74 in FurMark easily.

Thats not really dangerous, but its very weird considering 460's are rather cool cards. Mine hits 50c overclocked playing GTA IV for an hour. I would look into this problem first before overclocking, But yes 70c+ is pretty hot for a stock 460

Yes they can go to 100c but not for long, 70c for a 460 is hot.

Well that was after two days of Furmark. Il see if it goes crazy when I add some volts
