Card overclocking.

post #1 of 10
Thread Starter 
8800gts.......... Is it as simple as downloading rivatuner, up the core and memory clocks about 5 mhz and play something or a run a 3dmark test to see any problems. if there isnt any, then repeat.

Is there more to it other then antialiasing and other small things like that? Also, when making the core and memory clock faster, with antialiasing run better at a higher setting?

Just downloaded ATITool and noticed the two options for finding max core and finding max memory so I take it that is all there is to overclocking a card as far as main aspect gos.

However, I started running the find max core and it went from 513 to 642 and then my comp froze and I had to restart. It was also at 83c, is that to hot?
Will the Atitool stop itself if somthing is wrong or if temps reach a specific point? Is 642mhz my max since it stopped there?

83C is getting a bit hot yes, if it freezes up then it's unstable so clock it down! Use ATiTool and raise the clocks up by a few mhz every time (~10-20mhz?) Then scan for artifacts for a couple minutes, keep doing this until your card can't handle anymore

The atitool auto-overclocking is decent, but a lot of times it will continue to increase clocks even though there are problems. Your best bet is to just up the clocks for each by 5mhz at a time to make sure they are safely stable. However, I advise you not to go above 626 core because the real-time shader clock and core clock, although seemingly raised, will not change from 626 to ~645mhz.

I would start out at 600 core 1900mem and just up it 5mhz each time from there and keep checking with 3DMark06 or a game.

Most likely you'll reach 625/2000 without an issue.

so what is an ok temp for an overclocked card? Is it safe to run the find max core and clock until something goes wrong, then turn it down about 15-20mhz and try again? Or should I not be doing this?

It's better if you do it manually and as for the temp, I'd try to keep it below 85C on max load.

get ATItool BUT

imho, DO NOT use the "find max ____" tool. my brother used it while i was gone, and when i came back he told me that the core upped from 350 stock to almost 700..... it fried. the problem is that the tool has a hard time recognizing very minor artifacts, and a very minor artifact can lead to a system crash in about 5 secons if your not careful.

up core and mem around 10mHz, and then run artifact scan. if at any point the computer starts glitching, especially during a heat up phase, STOP CLOCKING UP. if you go any farther, it will burn out.

hope i helped out a lil

is there anyway to set atitool to stop at 85c? Its getting to 88c on 600/1000 without problems, but since its that hot, is that as much as I should go or even back off a little?
