Core Unlocking Problem w/ AMD Athlon II X3 435 to Phenom II B35

post #1 of 7
Thread Starter 
So, yesterday, I installed my new motherboard (MSI 880GM-E41) and 2GB of 1600MHz Kingston HyperXblu memory. I installed Windows and went into BIOS. I successfully unlocked the 4th core but now, whenever I go into a system informations program the CPU clock is at about 800MHz but it also jumps to 2900MHz (the default clock). I need to mention that I never did any other OC except the core unlocking. Is it a problem? Should I leave it as it is? My PC hasn't crashed so far and it seems to be working well.

Also, when I'm in idle my cores run at about 2-3% load but when I install a couple of programs, extract some archives, my usage goes to about 17-25% on my 4th core (the unlocked one) and stays at about 10% on the others. Is it normal?

Thanks in advance.

Thats Cool N Quiet man. Your clock speed is downclocking to 800mhz to save energy and heat. If you do not want it to do that disable cool n quiet or power now in bios.

As far as the cpu usage. That always varies per core. Perfectly normal.

its best to test it with prime95 for about an hour or two
if it doesnt crash/bsod/freeze ect.. its fine

c&q and c1e downlcock and undervolt the cpu while idle
disable them in bios

watch the temps, with hwmonitor (cores will be broken since its unlocked)
make sure the socket doesnt go over 65c (socket is normally about 5c under the cores, lock it for one boot and test under load to make sure)

I'm not really that pro. I understood what you mean and heard that Cool 'N' Quiet does this but will disabling it affect something in my CPU with the core unlocked. By the way, I use a very good aftermarket cooler and the CPU is pretty cold under a heavy load, about 30-32 degrees Celsius in 60-70% load. So, I shoudl disable CNQ?

Cool'n'Quiet is normal for AMD processors. What I would be more worried about is the board, with that cheap 3+1 phase design you would be approaching and perhaps exceeding the board's TDP limit, and the risk of catastrophic failure is high on this brand. Unlock with caution, I recommend you keep locked. The aftermarket CPU cooler only makes it worse over stock as it removes all VRM cooling.

What board are you talking about? My sig rig is old as shiz, I didn't update it...

Okay, so, I read your article about VRM and decided to lock the core back up. I really do think it's a tad bit faster as the whole unlocking thing ate from its core clock and it's safer to keep it locked indeed. I will be using MSi Control Center to OC the CPU a bit to a game state, bring it to about 3.1 or 3.2 GHz. Thanks for the tips guys.
