X2 4000+ stuck at 3.0GHz

post #1 of 20
Thread Starter 
I used to be stuck at 2.9GHz and couldn't figure out why I can't hit 3.0GHz stable no matter what vcore I used, until I bumped the dimm voltage from 2.2v to 2.3v which is now my 24/7 setup.

http://valid.x86-secret.com/show_oc.php?id=330782

vcore 1.3v
dimm voltage 2.3v
specs in signature

Now I have a 9600GT, and my proc is bottlenecking it. But no matter what I do, I can't exceed 3.0GHz.

I've tried dropping my HT and ram dividers all the way, but even at 1.45vcore and 2.4vdimm at 300x10.5=3.15GHz my system will post, run a few loading bars in xp, flash a blue screen then restart. I haven't tested if 296x10.5=3.1GHz was stable, but I was really expecting a 3.2GHz overclock from this thing, especially after I upgraded to OCZ mems and a true120.

I'm really aiming for a useable overclock, e.g., not too extreme on voltage, HT and ram frequencies and latencies >= stock. Is 3GHz really as far as this can go?

That might just be the max your cpu is willing to go. You may be able to squeeze a bit more with watercooling. Also try lapping, I hit a wall @2.8, but after lapping I was able to hit 2.9 with the same voltage.

3Ghz out of a 4000 is hardly stuck, to go any higher, if possible, you'd probably need 1.5v+ maybe even 1.55v to do it.

yeah, that's a fantastic AMD overclock. You don't even see too many Windsors going that high.

I wish i could get my 4800+ past 2.68 =(

I've owned 3 different 4000+ brisbane chips and they all maxed out at around 3100MHz with ~1.5v, so I think you've found it's limit....

Even the true120 doesn't mean much when the mobo ambient temps are 37C, so 1.5v is way too high for 24/7 use...

i run mine over 1.5 volts all the time it's fine .. though it is water cooled



arkheii What 3d marko6 score do you get as i want to buy a 9600gt ?
