i always get a blue screen popping up and if i go over 3.6ghz my computer doesnt boot. i know this cpu is easily overclockable to 3.8ghz, so is the problem from my motherboard or is it from something else

my specs:
amd phenom ii x4 955 BE
MSI 870 C45
Consair XMS3 2X2gb 1333mhz
coolermaster hyper 212 evo
xfx hd 5830

have you adjusted your CPU voltage?

I got the same setup as you and really there is not much difference but instability and heat increase 3.6ghz is the money for Phenom II 955 anyway.

Have you read through this guide yet? It will help you a lot. What temperature are you at when your clocked at 3.6

I had a 965 BE which is really similar in performance
I was able to hit 4ghz stable
I will try to post up my settings as best as i can remember them
warning every CPU is different so these settings are only a general guideline

FSB/BUS/Reference clock - 200 - I wouldnt really change this too much on a BE unless going for extreme OC
multiplier - 20 - of course start off with a 19 and see how that works
CPU voltage - 1.53v - from all of my reading Phenom II Deneb series are pretty safe up to 1.55v but make sure your temps dont go much over 55c and definitely not higher than 61c
NB frequency - 2800mhz though I would start off with 2400 and move up from there- you should be able to leave your NB voltage set to auto or just raise it a few levels up from stock setting
HT - 2000mhz - no reason to raise HT frequency since it doesnt increase performance
ram I would set for stock settings from factory which for 1333mhz would normally be 8-8-8-24 but starting off with 9-9-9-27 would be good until reach stable OC and then tighten timings- set command rate to 2T and then try 1T once you are stable
PCI frequency leave at 100

you should be able to get between 3.8-4.0ghz with a 955be depending on ambient room temps and case cooling
I hope this helps
