Phenom II 955 BE 1st timer

post #1 of 31
Thread Starter 
Hello i bought new pc with AMD Phenom II x4 955 BE procesor.
I want to OC it, but never done before so its complicated for me. I need your help with going on it.
i did some changes here is my OC settings

General question is to go highter or not, if yes how?
temps in C
MB always 32
while doing nothing
core 40-40,5
proc 40

while overdrive stability test
core 52,5-53,5
proc 49

If i go more then 20 multiplier iam geting BSOD

Another question. Is it OK my FSB set in 800MHz while CPU-z showing max bandwidth 667 MHz. But Kingtone says it works on 800MHz. Should i lower FSB?

Try searching the forums and reading some guides on the subject. Lota of great info contained on these forums. Also just a tip, never use AMD Overdrive to overclock, always do this within the BIOS.

sounds like you need to up the vcore to 1.45
post #4 of 31
Don't use any software to overclock u will not get anywhere. Do it in the bios. But here is what you can try to get stable.

Up cpu voltage to 1.45 (1.55v is the safe max volts for air cooling)

Get the cpu-nb up to 26-2800mhz (same volts apply here)

Play with the RAM timings or atleast the ram speed (safe volts for ram is around 1.65) you can go higher but i never seen anyone needing more.

Keep the HT-Link close to 2000mhz, you get no performance boost here just instability.

phenoms don't have FSB

good information in these two threads:

http://www.overclock.net/amd-general/525113-phenom-ii-overclocking-guide.html
http://www.overclock.net/amd-cpus/499526-official-phenom-ii-x4-9x5-oc.html

You're going to need more voltage to hit 4GHz right off with just the multiplier. Some of these will never hit 4GHz stable on air even if you use the max safe 1.55V. Just make sure you watch your temps. The max safe is 62C.

You would probably get better results starting over and using a combination of Ref. clock, NB, ram and multiplier instead just cranking the multi all the way up.

Thank you for advice, but you confused me. You said i need more voltage to hit 4GHz, but i already have 4GHz with 1,4V its 200MHz x 20 multi with those temp i have wrote. Iam using Prime95 so far ok, no problems.
You said 62C, but in Core or Proc?

Try using 16x or 17x multiplier, from my experience these are the best multiplier for my 955.
I use 250x16.5 to get 4.1Ghz and 1.5v.
