Asus M3A78-T + 9950BE overclocking... wow its all new again

[Jimmer411]

Yes I did try turning down the NB multi but was still unable to boot at 260 HTT. Right now Im running dual orthos at 246x13 with SB Clock Spread Spectrum disabled. I attempted to run dual orthos while at work at 249 and it crashed tho Im not sure at what time it happend. Same goes for 246x13 overnight. Im hoping that stupid setting is the culprit because Ive been able to play COD4 and Stalker just fine at these settings.

What do you guys use for testing stability in Vista 32/64? Could there be a chance that orthos just isnt the way to go with vista?

Orthos should be able to just fine from what ive seen and read for Vista.

Phenoms are very sensitive to High HTT/fsb Above 240/250..( Volts on the HTchipset to 1.28-1.31v are safe to use
24/7 with stock NB/SB heatsinks)

Ive found that some memory dividers will work better than others because of freqencies the phenoms run at..

The Higher the HTT the lower the Highest Oc will be ..

@288 i can only run Max CPU @ 3340mhz no matter the Volts or NB/HTT/HT settings.

@ 260 i can run 3450mhz STABLE but not Stable @ 3.5ghz NB2680
@ 250 and lower i can run 3450+mhz with Max NB 2690

Depending on the memory divider and BIOS will determin how how it can go..Even using HIGHvolts i can NOT go above 3340 @ 288+ with high NBfreqencies

There are so many variables with HTFreqency . Seems CPUxmulti and RamXmulti are a main key for stability.

Using DDR2-8500 1066ram allows a better Oc in my opinion unless you have real good 6400 that can run 533+..

@ 266 i run my Ram @800 = 1066 5-5-5-15-2T

Some memory xmultis will work better than others with same htt/ht setting.. i can use 533 but not 400 . I can alsouse 800 and 1066 but not 667 dividers when i try any HTT/HT combination. Memory dividers will chage as the ram and HTT go higher some just work better at all speeds vs others..

But to go Higher with HTT only causes you to lower your Overall OC and stability by not keeping things closer to 2000HT and HTT

My Max (Not Prime or orthose stable)..More of a Suicide runThe Boards PWM's fail @this speed from heat. i can only do this run with HTT200



34.8ghz/Nb2680 .. that goes out the window once i try to raise HHT over 268..but if i keep it below 260 i can do 3.5ghz with a little less on the NB with better performance.



Overall CPU is Higher but with lower HTT on this run...Performance is better @3.5/nb2600 vs 3.84/nb2680



Last this is what i am Running ATM 24/7...



BIG NOTE: these runs are with HIGHVOLTS (CPU and NB above 1.55v "Do not try this with out XtremeCooling"

High HTT isnt all that and i can get the same performance using lower HTT = Stability @3.45ghz vs 3.5ghz HTT260 and be UNstable.

P.S.
Didnt mean put so much,, Sometimes its easier to just see why ,,than for some one to type numbers
