My Budget Mobo Overclocking Problems

post #1 of 9
Thread Starter 
Hi Everybody

Today i bought a big cpu cooler, and tried to overclock my cpu for the first time

the thing is my mobo freq is almost limited to 212, not like the other people, i cant do more than 212, so i stuck at 3.82 ghz.

if i unlock cores (x4) i cant see temps, so i try in x2 now and i want to know,
which part of my budget config bad, so i cant do this 4.4 ghz?

bus speed 252 ?? also memory timings??

the RAM is probably causing the bus clock limit to 212MHz. It's probably not so good generic stuff at 1333Mhz CL9. Many generic RAM kits top out at around 1400MHz due to IC binning.

The motherboard VRM setup (weak 4 phase) will hold back your CPU from high overclocks when 4 cores are activated due to high power draw...

which one should be replaced for reaching 4.0 ghz with x4 config?

now my achivement

http://valid.canardpc.com/show_oc.php?id=2071113

but 19x stable 19,5x unstable

i see my max temp with 2 cores @4 ghz is 38 C*

so now i'll start to try blindly with x4.

about phases, i start to read them, as i understand my mb is weak, and with 4 cores somehow hwmonitor says my cpu uses 160W ??
i dont change any voltages, so im not gonna burn this right?

The motherboard. It will not handle a 4GHz x4 without serious performance loss during load due to VRM overload-induced CPU throttling. There's not enough phases on that AM2 base design board.

I was waiting for that lol

dude the motherboard will fail silently.. you are pushing too much into the motherboard.. its only designed to hold a maximum tdp of 125w.. dont push it any further.. it may damage the processor and the motherboard!!
