i5 2500k OC (NEWBIE HERE)

post #1 of 7
Thread Starter 
hi guys, just recently oc my i5 (new to this) with vcore of 1.21

but my question is why is it when its in idle, my clock speed changes to 1600MHZ and a vcore of 1.185, is that safe? how do i change it so it idles on a safe vcore (or is it already on a safe vcore)?

EDIT: 4.5GHZ

4.5GHz at 1.21V is pretty good. have you run Prime 95 to stress test it and see if that oc is stable??

at idle your cpu will downclock to 1.6GHz to protect itself thumb.gif

yes I have used prime95 but only on the first setting for 8H and had no problems for 2weeks now.

okay is that safe for its vcore to go that high at 1600ghz? or is this a silly question

on stock settings 3.3ghz was on 0.9XX vcore and I was a bit worried

cool, thats since you've run p95 8h you coulkd try a larger FFT and see how that goes just to confirm its stable.. otherwise you have a good Chip there that could prob break 5GHz using water cooling.

1.185 is ok for idling at 1.6GHz IMO and there is no such thing as a suilly question, only silly answers LOL thumb.gif

thank you so much!
I don't really know much to OCing, I used a guide
here is the picture http://i.imgur.com/NCBUi.png
also what is BCLK?

BCLK = Base Clock or is Bus Clock cant recall.. but you should not change it, usally its 100MHz but a think it can vary between 99 - 101 approx. this is for sandy bridge chips like your I5 2500k and you should not let the BCLK get or set it about 1 MHz over 100MHz.
