8800GT OC

[mdk88]

Have a BFG OC 512MB 8800GT.

It's at the clocks it arrived with at the moment, and with fan set via rivatuner to 60% i've never seen temperatures top 55 degrees, even after upto two hours of cod4 on high at 1680 resolution.

Had to RMA my first 8800GT as it stopped booting ( never overclocked ) so i've given this card three weeks at stock to make sure of stability. It seems fine.

Anyone got the same card and can reccomend safe clockspeeds to set in rivatuner? Or is it best for me to twiddle until games don't crash ?

How should i do it ? Adjust one setting at a time ? Not OC'd a card before...

Also, is the potential gain worth the effort and or risk, with regards gaming performance?

What are the clocks for your OC'd version?? Mine isnt a BFG. My stock is 600,1500,900(1800) I havent noticed a framerate difference in COD4 with my highest OC of 700,1750,987(1974). But it really helped in crysis bringing up the minimum fps and making it smoother to play.

Depending on your clocks now, just start with the core and put it up 15-20mhz. http://www.ozone3d.net/benchmarks/fur/ is a very good stress tester.

Risk wise, mine would lock up during a game, normally crysis and id have to reset if I had gone to far. Though its possible worse could happen. Depending on its default OC'd speed, you might not notice much difference in game.

It's probably best for you to do some testing yourself to see what clocks your card will happily run at. In order to do this, I would just raise the sliders 5-10Hz at a time and then try some games to see if they run ok with the overclock. Depending on how high you want to/can overclock, you'll want to increase the fan speed a bit, you should find that anything upto 40-50% should be reasonably quiet, as your case fans should drown the sound out. I've not tried mine in games but it'll happily run 3DMark06 @ 740/1854/1015

On the fans front, i found it best to set fan profiles in ravatuner, for example at idle the fan spins at 60%, when the temp goes above 50C it ups to 70% etc etc until 70C where it would hit 100% (not that it ever goes anywhere near that).

From what ive read the ream on a 8800GT should generally be left alone, the core has easily gone up to 680 and i left the shader linked so thats running at 1700 perfectly happily. I'm sure i could push the core further but there really isnt much point - it handles everything but crysis perfectly, even bioshock with DX10 enabled.
