hey guys.. I'm looking to do 3GHz on an X2 4400+.. here are my specs..

AMD Athlon64 X2 4400+ (Brisbane)
Biostar TF7050-M2
2GB OCZ PC2-6400 Dual Channel SLI-Ready
XFX 7800GTX 490/1300
Keian 550W PSU

here's where I am at the moment..



vdimm is at 2.2V and it's holding.. I've done orthos for 9 hours and it's pretty stable so far.. however.. when I try to do anything over 285MHz for the FSB, it just locks up.. it wont even load Vista..

the temps are somewhat acceptable.. it's doing 36C at idle.. and shoots up to about 61C on full load.. this is all at room temp (when I say room temp, I mean around 21-23C.. it's winter) the CPU temp in speedfan (in the pic) is the temp for when I was running a UT3 timedemo (for about 3mins)..

any advice?

hey thanks for the reply.. this is a list of what I've tried..

try 1:
Multiplier: x11
FSB: 280Mhz
vcore: stock + 0.200V
vdimm: 2.2V
NB: 1.36V

will POST but wont boot into Vista (BSOD)

try 2:
Multiplier: x11
FSB: 280MHz
vcore: +0.250V

will POST and boot into Vista but immediately BSOD

try 3:
Multiplier: x11
FSB: 275MHz
vcore: +0.250V

will POST and boot into Vista but starting any programs will induce BSOD

try 4:
Multiplier: x11
FSB: 275MHz
vcore: +0.275V

will POST and boot into Vista.. starting programs kinda works but only in some cases (corruption?) eg. CPU-Z runs but UT3 time demo wont.. at this time CPU temp was 40-42C at idle..

try 5:
Multiplier: x11
FSB: 273MHz
vcore: +0.275V

about the same as try 4..

right now I've reverted back to 280x10 @ +0.200V which seems to be the most stable so far.. I have a policy of keeping the idle CPU temp below 40C.. maybe I should look into some better cooling? how's your system handling the heat?
