Manage to unlock my Phenom II X2 555BE to X4 B55 with Biostar TA785GE 128M board ....
Able to get a stable voltage of 1.47V with 49C max @ full load for 7.5 hours prime95 test as if below this voltage the 3DMark 05 fail...AMD 69xx Owners Club thread .."HD6950 not passing 3DMark05??"
Last 9 ... i try to OC it using the multiplier on AOD but i think i only manage to get 3500 (200 x 17.5) ..need advise how to obtain 3800 (my target) as i try to go 18x my WinXP restarted
I saw a lot of members here able to go between 3700 and 4200 .. Is it my motherboard limitation?...i only notice there's a member here using the same board as mine...Help require;)
I think to be fair, that while pc-illiterate's
advice should be taken, it's much moreso orientated toward boards with lower quality VRM's, and when pushing the voltages very high. gappo
was comfortable pushing 1.6v through this mobo
(just added some Enzotech heatsinks to the MOSFET's. Though normal people shouldn't exceed 1.5v for 24/7
), and Biostar usually have good quality FET's.
See here:- http://www.hardwaresecrets.com/fullimage.php?image=19183
. They aint NIKOS, they're ON Semiconductor FET's.
If you plonk on some Heatsinks, it'd be great, but I don't think you'll be limited for a 3.8GHz OC running ~1.45v .
I think you'll be fine if you keep it under 1.45v, I also think your problem is the fact you're just using the multi and VCore, you need to add CPU-NB and other things into the equation.
Here are a couple of good guides, to help you understand the process a little more in-depth.:-
Take note, Blue Screen is usually NB/CPU-NB related, Black Screen is usually VCore/High Clocks and Restart/Crashes are usually down to the Temps peaking.
You need to ditch AOD and do everything through the BIOS.
For me, I got 3.7GHz with 2600MHz NB I needed 1.492 VCore and 1.311 CPU-NB. I coulda got the voltages down, but I was just jumping up for quick Overclocks, had 3.6GHz @1.42v/1.22CPU-NB.
Best of luck mate.Edited by EvoBeardy - 7/6/11 at 5:21am
