Need help, sometimes it wont POST

post #1 of 4
Thread Starter 
Hi guys, need help on my pc
i've been visiting this forum for a month now and decided to create an account,

i unlocked the 4th core of my Phenom II 720 BE
and overclocked it to 3.5ghz
it passed OCT 1 hour/ 8 hours of prime
i adjusted the cpu voltage,Nb volt and lower the clock of the ram to 6
and it seems that its stable i was able to play games and do some stuff on the pc without having problems with it
but the problem im having is that, everytime i turn on the computer after its off for couple of hours it wont POST
no display on the monitor, no beeps, fans are just running
i need to press and hold power button several times or press reset button until it will show the POST

here's my spec
AMD Phenom II 720 x3
2x 2gb kingston 1333 ddr3
ati radeon 4770 512mb
emaxx 785g-fxn motherboard
antec truepower 750w
Deepcool Ice blade pro

THanks in advance

your ht link is too high probably. drop it to 2000mhz. should help quite a bit.
i would also raise the timings on your ram. 6-6-6-15-20 ? is the 480 ram = 1440 or 960? could be a culprit. raise timings to 9-9-9-27-36
could also be the motherboard vrm's overheating but if its off for a few hours, doubtful.

i would start over and find your highest oc using just the cpu-multi and adjusting the volts.
set your ram at its rated timings. what does it tell you spd is cpu-z ? did you raise the ram voltage ? might need to set it at 1.65v
start with a vcore of 1.4v. up it when you need to.

there is always the possibility that your 720 is just not stable unlocked.
so try unlocked and 2.8ghz with 1.4vcore and see if you have problems then. make sure you set timings at factory recommended.
see if you can run p95 for 6 hours. overnight at bedtime would be great if you sleep for 8 hours.
you must find out if its stable unlocked first.

sorry its a long post. if youve done/tried all this, post what all youve done/tried and the results.
