mabye you need more watt power supply
because you overclocked
My power supply is function normally. I think the PSU has no problem .
Here is my spec:
PSU: coolermaster 1200 watt
cooler: corsair h70
RAM 2x2gb 1333 kingston
radeon hd 5870
window 7 32 bit.
Every time i overclock it. It just cannot boot. Even with raise up of 5mhz(135 to 140) base clock, it still cannot boot.
Anyone know how to deal it?
the cpu multiplier x the base clock gives you the ghz, but your ram and uncore are affected as well. If you are using a dram multiplier of 10 and you raise the bclk 5 mhz you would be running your ram at 1400 (140 x 10= 1400) which would be overclocking your ram probably beyond its abilitiy without loosening the timings or raising volts.
Why the smackover shows the base clock as 135 I never did figure out but the true base clock is 133. The default ram multiplier is 10 (10x133=1333) so ya a 5mhz bump can cause your overclock to not work.
For starters you could try:
cpu multi 21
for a 3.150 ghz
ram multi of 8 (8x 150=1200)
uncore multi of 16 (16x150=2400) the uncore must be at least twice the ram
this will leave your ram underclocked, but it's just a start.
turn turbo boost off, otherwise when it kicks in the cpu multi will raise and so will everything else and maybe bsod
This should work without having to touch any volts, if it bsod, a slight nudge on the cpu volts would be probably enough to get it stable.

Hope this helps.
