Want to oc i5 2500k safe & easy?

post #1 of 8
Thread Starter 
Just finished this build a couple days ago, (first build) and want to give overclocking a try. What I'm looking for is a safe way to do it.
Questions: Do I have to download special programs or can I go directly into my overclocking in BIOS and change some settings safely? If so which ones and where is a decent place to start ? Can I say...., get it bumped to like 4.5ish without any troubles? I realy don't have a clue how to work with the stress testing or other corisponding downloads. Probably alot of newb questions that seem dumb to most but I thought I would throw something out there and see if I can get a hand at getting some performance gains.
Thanks for your time reading this .

not familiar with your board, but I would say your best bet is bios software over clocking is not ideal.

[disclaimer]firstly and most importantly these settings are not definite all chips are different some will oc up to 5.2ghz some will never make it past 4ghz. I have not used your motherboard, I have not used your CPU the Bellow are simply the settings I changed on mine to get to a 4.5ghz oc so use them at your own risk. check everything carefully and be sensible.

that said. Firstly go into the bios and turn off pretty much everything you dont need. power save modes, etc

now change the CPU multiplier to 45. and the vcore to around 1.28v lower is better if you can certainly. will probably need to change the VCCIO not sure how high exactly but a bump of 0.010v ish should do it, VCCSA again around a 0.010v bump.

With all voltages try them lower first!!!the lower you can keep them and get a stable oc the further you can push your chip, the higher they go the bigger the risk.

Change the settings save them to a profile (if your board will allow it) and run it through if it wont boot, or BSODs in prime95 under stress test take note of the bsod number and bump the appropriate voltages. remember when chaning voltages, only do it by tiny amounts 0.01v is more than big enough to count as a "bump" Do not push your cpu voltage past 1.35 while trying for 4.5ghz if it hasn't made it by then it isn't going to :'(

Awesome! Thank you for your time. I will try this out and do "small" bumps and see where we get. I'll try this this afternoon and let you know where I get. Thank you for your time with this very much!

Well, wont be trying that again anytime soon! running prime stress test system crashed! Scared the crap out of me.... I went with a lower voltage to start and went with 44 multplier. Ran great for about 5 mins. then poof!

see if you can find a guide for you motherboard or someone with your motherboard to help you with settings. i know that if it wasnt for some that helped me i wouldnt be where i am now at 4400mhz . now i am trying to lower voltage a touch if i can its very annoying when you think its stable then it bsods

Dont be afraid of a bsod. It is there to protect your hardware and also giving you and error code letting you know what failed. You can usually tune your OC based on the the bsod error code. As long as your voltage/temps arent through the roof (1.35v is safe) you should be fine.

that is perfectly normal and to be expected, this is why we start with a low voltage, and why we prime stress test. bump the voltage up by .01 and try again. If that crashes assuming its still giving you bsod codes for low vcore (off the top of my head 0x101 and 0x124) nudge the voltage up by another .01 and keep going until its stable or your over 1.35v and not stable @4.4ghz in which case I would say your over your maximum stable over-clock.

The safe ceiling ultimately for sandy-bridge is I believe 1.5v you shouldn't be able to fry it lower than that. If you do RMA it they cant tell its been oced just tell them you left it encoding a video and the stock cooler was obviously not good enough to keep it cool or run with complete ignorance I have no idea why but its just stopped working

getting a stable over-clock takes lots of crashes you get used to that bsod its your friend

Edit:found a list of bsod codes and what they mean ocn bsod list
