Painless way to overclock XFX 7800GT

[andrei3333]

So i recently upgraded and my aging XFX7800GT cannot play the latest games to the max at 1280x1024 (i have a 17" Samsung)

system specs:
E8400 stock
GA-P35-DS3L
Corsair XMS2 2x1024 4-4-4-12 DDR2-800
Seagate Barracuda 7200.11 32MB cache Parallel write technology
OCZ StealthXstream 600W PSU

I tried using Rivatuner, but its strangely missing the test function
I also tried nTune, and it seems to test fine, but i dont believe the results

The card's stock OC is 450MHz Core and 1.05 GHz memory

I comfortably pushed it to around 480MHz/1.2GHz and passes the nTune tests, but call of duty 4 stutters..whats the easiest way to test the clokcs? i dont feel like opening a game everytime i increase like one clock cycle

Is it ok to open the game and switch to windows to adjust the clock ? or would the result not take effect until the PC reboots or something ?

The clocks stay when you apply them until you reboot (unless you set them to start with Windows).

So after setting an increase, you can run something like...
ATiTool's fuzzy cube: http://www.softpedia.com/get/T...eo-Tweak/ATITool.shtml
or RTHDRIBL: http://www.daionet.gr.jp/~masa/rthdribl/

(or a game or 3DMark, etc.)

I personally like ATiTool's test, as it finds errors faster than anything else i've seen.
Obviously you'll want to verify the results in actual games though eventually.
