Signs of Hot trouble?

Hmm that fixed it. Now its running at 4018 Mhz. Temps shot up b 7 to 10 Deg overall though.

Moderate gaming is causing 57 Deg which is well below TjMax of 79 Deg hence not bothering.
Thanks for the Tip.

^^ mine also ran at same speed with same amount of cpu vcore but I've decided to run my 955BE at stock speed with 1.25 cpu vcore for the time being - once the summer season is over I'll bump up the clock speed again.

The 800 Mhz boost is really showing effect in WC III launch speed.

Why Wait you got CM 212 also right?

^^ yep, but I think the games I'm playing right now ( Kingdom of Amalur ) don't require that much cpu power - so saving some power to see how efficient a cpu can run at stock speed with lowest possible cpu vocre - I was able to successfully run the cpu with only 1.225 cpu vcore at stock speed but as I was facing start up issues I've to se;lect 1.25v - anyway, will experiment with 1.2v cpu vcore only next time

Well I bumped Multi to 20.5 and not its running at 4118 Mhz.

Anything above this and its BSOD.

Whats the Way forward? or I have hit the wall of Air cooling

Changing BUS frequency by 10 MHZ..i.e. 200 Mhz +10 Mhz also giving BSOD.

^^ only way is to bumping up the cpu vcore but don't go over 1.55v with Air cooling but even 1.55v is risky in this hot summer season ( and cheap mobos don't have VRM heatsink, remember ? ) and don't let the cpu temps cross over 62c/65c.

I think 4 to 4.2GHz is pretty much the Wall for PH II. Performance boost received so far is enough and I will try to reduce Volts to 1.45v to reduce temps.

 

[topgear]

in my case anything lower than 1.5V was not enough for 4Ghz.

check how many phases does ur mobo has... gigabyte has an 880g with 3+1 phase if you have that board..... dial down the crazy on the Vcore you could still scale the clocks up with lower temps...

and phenom II's "wall" is ~7GHz...

also check how stryker black e oc'ed his system thats how u should OC too.... only clock speeds dont help in increasing performance...

I meant to say for air cooling man. Whos gonna pour LN2 24x7 to keep it running at 7 GHz

And can you provide the link for that OC thing?

Yea, the wall suggests cpu's organizational/architectural wall... 4.1GHz is pretty much the limit on air for Phenom II X4 955...
