8800gtx overclock

[mcbacker]

Mine does 660/1600/1025... Never tried to go higher.... no artifacts at all ;)

That won't work too well, I don't think. You need the heatsink sitting over the GPU.. not the back of the card.That will work. The HR03's heatpipes will allow the heatsink to mount the other way. That addin fan card would work to cool the RAM sinks. No problem.

So which overclock produces the largest gain in frame rates in say Crysis for example? Core, shader or mem??

I have my ASUS 8800GTX clocked at 620MHz core, 1600MHz shader clock and 2000MHz Memory clock. Can't seem to up the shader clock much higher, at 1650MHz the GPU will freeze so have settled at 1600MHz.

Funny enough the Gainward overclock tool works with all driver versions and allows you to overclock shader by them self.

I believe the core clock jumps from 621 to 648 around the 635 mark on the rt over clocking tab. Check with the monitoring tab when oc'ing. I had recently set mine to 660/1600/1050 via rt. When I opened up the monitoring window in rt, the graphs read 648/1620/1053. If I changed the core to 636 it would still read 648 in rt monitoring window. At 630 it read 621. Must be set to certain cycles I guess. I ended up matching the graphs clock with the oc tab clocks at 648/1620/1053.

For a great, quiet two-slot cooler you can't beat zalman's VF-1000LED with the ZM-HRS88 (for 8800) heatsink.
