Overclocking a 7800GT

[xxxjwxxx]

I'm a noob and just wanting to get some help w/ overclocking my video card...
All I can overclock to is 448/1172 on my EVGA 7800GT...

My 3dmarks05 came out to be 7438...

I have a a64 4000+
(2) 1 Gig PQI RAM
the EVGA mobo (not SLI)
umm I think thats about it?

Can someone guide me on how to tweak this farther? I'm not really interested in tweaking the CPU speed... Thanks =)

Oh BTW, I use rivatuner if that helps..
Also, if I go any higher the computer freezes during the 3dMark05 test.

I got my EVGA CO up to 505/1250 with Coolbits. Is there any chance something else is crashing 3dMark? It was crashing on me the other day because I had set my RAM Voltage too low.

hmmm how do i check if my ram voltage is to low? My temps aren't even getting that high.. I know they go up to about 72... Sometimes I get a lot of artifacts and then it freezes or somethings, ill get just a little bit...

Maybe temp is limiting your OC? Do you have a cool case?

ya, i would think i do... I have two intake fans, probably about 80mm, and 3 exhaust fans.

my PSU is a enermax... I forgot the model #...
