Can u guys give me any sugession which should i do..replace RAM or PSU..?
My problem is i can POST the BIOS at 3.7Ghz but i can't get higher then 3.15Ghz with stable OC.It BSOD if i try to OC higher then 3.15Ghz.
I'm new OC..
I wouldn't necessarily suspect hardware right off the bat, although some components do not overclock easily or as well as others. Take a look here. ->Overclocking Guide
Some of the guys here at Tom's worked hard to put together some really good overclocking guides. If you read through them, you'll get a good understanding of the basics as well as some trouble shooting guides in the process. Good Luck.
To add to all of the comments above. Yeah, on stock cooler, don't expect to get that high, especially the crappy old intel stock coolers. Those things can't cool for ****. I suggest you also look into uping the memory voltage as the memory instability may be because of the ram voltages or cpu voltages.
check this out.... gigabyte.... i have the p55a-ud4p, i was stuck on 3.4ghz also, and this is how i fixed that problem.... 1) go to "Advance volt," in there, there is a profiles option in there.... 2)change the "standard" to "turbo" and 3)waLA! you can now OC past 3.14ghz.
please, manually adjust your vcore and MAX your DRAM volt if you haven't yet.... you will save on ALOT Of HEAT!!...... i am using 1.175v on my vcore and i OC it to 3.82ghz
ALSO, keep a GOOD eye on your heat, since you are running a stock cooler on your CPU..... UPGRADE that for a safer OC!
i read your question wrong... is your vcore on auto? what values did you change on your MB? need more info of what you are doing, either you left stuff on manual, disabled and gave it a value, OR/AND tuned things on or OFF...
I didn't notice stock cooler... Oh god. Please please please run some tests and watch the temps. I guarantee it's getting overheated too... I installed an E5400 I think it was and even just at 3ghz with stock cooling it was at the temp limit...
Thanks for all ur support guys
I had enough with that mobo..
I have change to G41M_Combo.All same specs.
I can reach 3.50G (333 x 10.5) at 1.55Vcore.5-5-5-15 2.1VDimm.Max temp at 72C.Pass all 25tests with IBT at max stress.Prime95 pass for 10hours without any error.
But...still using Intel stock cooler..
What should i do to get low Vcore.?Should i change PSU?
I can reach 3.8G at 1.58V~1.6000V stable..I haven't test P95/IBT more then 5 minutes..coz temp reach 88C-91C
So its better to stay safe at 3.5G coz still use stock cooler.
