Sandy Bridge OVerclock help.. NOOB - Page 2

post #11 of 18
it depends on teh chip and the cooling. i have found that most can do 5ghz, some can't. its give and take. One easy way to find out is see how high you can POSt without cpu pll overvoltage, then your max will be 4-5 multipliers above that. if your max is like 5.3ghz then 56ghz stable is easy, if its 5ghz then it wont be easy.

Before I figure out my max by seeing where it fails to POST, which i went ahead and looked up to educate myself about haha, you mentioned in your guide "If you have retail CPU please enable Internal CPU PLL Overvoltage option. " But in your reply on my thread you said to disable this option. And I am guessing by retail you mean purchased new by intel? Im probably just misunderstanding lol but should i enable, auto, or disable this option in BIOS? And should i disable all the options you suggested before or after i figure out my MAX? Sorry with all the questions lol

Nevermind i misread what you said. It is clear you want to enable PLL overvoltage option haha.....so my only questions are should it be set to enable or auto? and should i change these options before i find my MAX or after?
post #14 of 18
you want it enabled not on auto. yea you can do it either way man, its just easier to find your max by turning it off and then see what your max multiplier is, turning it back on will yield you 4-5 multipliers higher.

Used advice. my computer failed to boot at 5.1 ghz. I cleared cmos then configured the options you said. I decided to just leave it at 5 ghz and keep playing with the Vcore voltage. I initially set it to 1.44v. With this i was able to get through the intel burn test on max setting with temps jumping around from 75 to 85. I wanted to see how low i could have Vcore volts with it stable at 5ghz. So i droped it down to 1.3v and it crashed during the Burn test. Uped it to 1.35v and it still crashed lol.. I guess 1.4v was a lucky guess? haha i ran the test one more time at 1.4v on max to be more sure so i could then go ahead and overclock my RAM (kingston hyperX 1333 8gb 2gbx4) So i read the section in your guide on TDDP and the DRAM voltage and them to 1.15v and 1.64v accordingly to up my RAM frequency to 1600. I left the cas at 9,9,9,24
After that i did the intel burn test again at max settings. It passed it. But then in the middle of the night, i left it on to download something, it crashed. Before i left this morning, i uped the Vcore to 1.45, the DRAMv to 1.66 and the tdd to 1.2. I uped both of them because i am not sure how to tell which one caused the crash because i got it to pass the Intel burn test both ways. Oh and i do have Load Line calibration (enabled), in my BIOS i do not have the option for Level 1 or Level 2. I will check to see if it crashed when i get home tonight, but any suggestions would be great.

When using intelburntest are you setting the # of threads to 8 or leaving it on auto?
If leaving it on auto you are only stressing at 50% load.

Prime95 is actually harder to pass with the sandy bridge systems, with x58 it was linx & intelburntest that worked it harder & got it hotter, now with sandy you can stabilize linx or IBT & then crash 5 minutes into a blend test on p95.

What else can i tweak to make it more stable besides what i listed ^^ because i don't know about the other adjustable voltages. I really don't want to go over 1.5v on Vcore, because i use this computer just about everyday for gaming or just normal, non cpu stressful purposes and i really don't want to fry my chip.

I'd be wary of that APEVIA Power supply.

You have lots of decent hardware, it would be a shame to see it go up in smoke from a crap PSU.
