Max OC for 7800gt?

[Bonerheimer_c]

What are the highest settings you guys have seen for 7800gt's. I currently have mine running at 545Mhz core and 1185 mem. Just wondering if someone has pushed their core much further.

In xs.org guys have 11k in 05'mark and core was much higher than yours.

It seems really weird that your 3dmark scores would be that much higher than mine when my core and mem clocks were higher than yours. I thought the 3dmark score for 05' only took graphics into account for your final score, and the cpu score only began to affect the final score in 3dmark06. Why are you mem clocks so low, stock is 1000Mhz?

Maybe you lowered your mem clock in exchange for tighter timings?

Thats not strictly true, whilst 2005 is a largely Graphic performance benchmark (2006 being about 50/50 CPU/Graphics) in 2005 CPU performance will of course show as many mid to high end cards with not particularily fast CPU's are "bottlenecked" and therefore the CPU plays a large part in card performance.

If you look at my spec, my graphics card is fast, my CPU bottleneck ends when my processor hits about 3.1 Gig so there is practically no difference in score between my CPU at 3.2Gig but under 3.1Gig there is a significant difference.......make sense?

Ahh I see. Thanks for the clarification. Now if only i could get my motherboard FSB over 315...

725x2=1450Mhz
GPU@1.5v, Vdd 2.26v iirc

Thats strange that your memory clocks report like that. Mine shows as 1190. I'm guessing thats my effective clock though and not 2380. Is it an option you can configure in ati tool or just a version difference? Anyway, 1450 memory for a 7800gt is pretty insane.

Sometimes you find that tho dependant on what application/version you are checking the clock speeds, take NVidia control panel for instance, it used to always say "800" meaning x2 therefore 16oo but on 93.71.....whatever the latest is it says "1.6gig".....strange but true.
