Help please... ok so i was excited about getting a second 8800gt to run sli.. unfortunatetly i didnt get any results. I thought this might be the case because of some of my older hardware. (I know not every game is sli enabled and gains are minimal. the nvidia sli meter also showed it was working) so thought ok time to oc.. i was getting 9200 in 3dmark 06, so i oc my amd x2 2.4 up to 2.6 and run it again.. and get a score of 10,100 something. pretty good i thought but read that i should be able to hit 2.8 with this cpu. so i bump it up a bit more and get to 2.7 it boots and runs stable. bump it up again(I was adjusting the freq by 5 with each try) and no post....
ok so i thoug i hit my limit i reset the cmoss and what not and was gunna run it at 2.7.
To my surprise no matter what bios settings i try my cpu shows no changes at all.
I took the ram to 133, the ht to x3, multiplier is locked x12, and bumper the freq. to 205.. and no change 210 no change 202 no change.. If any one has any idea whats wrong or what im missing please let me know.. thanks!!



mobo: foxconn nf4sk8aa sli 939 socket (maybe the prob im thinking)
4x1 gig corsair ddr 400mhz
amd athalon64 x2 4800+

In my experience athlon chips are not very good overclockers. I only have experience with an athlon 64 x2 5000 (2.6Ghz) and this would not OC past 3.1Ghz, so you may well have reached the limits of your chip.

I think the main thing holding back your sli 8800gt's is your processor. I used to have 8800gt sli and a q6600 @4.1Ghz and I scored 22000 in 3DM06. Upgrading yourself to a decent quad or dual core will likely boost this score, although it will mean a new motherboard and processor.

Wow I'd like to have that score..lol bad thing is i cant afford any new parts for a while.
so I'm stuck with having to get whatever i can outta what I got.. Any ideas why It will not change the cpu frequency any more?

In all honesty i'm not that up to date with overclocking AMD chips, hopefully somebody with more experience will be able to help, but if i had to guess i'd say its just the simple fact that your chip has run out of headroom.

By 'no change at all' do you mean it won't overclock anymore, won't register overclocks or is stuck at 2.7Ghz? Try downloading a program called CPUz and see what that says before and after an overclock. You may well have to make do with 2.7Ghz until you upgrade though. Not that thats a terrible situation to be in, as long as it still runs games who cares about synthetic benchmarks?

by no change art all im sayin it wont register clocks at all.. after i reset the cmoss it went back to the stock 200. It reads 2.4 again.. and no matter how i configure the bios it remains at 2.4. Im monitoring with cpuz already. If I use the cheap utility that came with my board the clock will change but its wery unstable that way( unstable @ 2.45 lol).. which from what i read is the norm for software overclocking.?
