One of the worst 2500k's ever? - Page 7

post #61 of 69
Thread Starter 
Es, passed both 1344 28 mins and 1792 for 37 mins because I for got about it aha
One concern I have, I've done theis technique before along with some runs of IBT, but when I ran blend it failed at another FFT, think it was 1200k

hmm, well the FFTs are unreliable and you could fail one 1344 and open again and pass another 1344, but for now lets consider this good.

So there you go, your cpu is pretty much stable now at stock volts..maybe you dont have such a bad 2500k after all? Only time will tell

Your next step is to simply increase the cpu multiplier until it doesnt load into windows or it crashes. Mine got to 4.0ghz before that happened.

Can boot into windows at 4.7 with SVID working its majic, think it was 1.344 but would instantly restart when I started prime
My chip seems to be a bad overclocker, I have emailed the company now anyway so they might just replace it and have the chance of a better OC'er but I'll have to see
I think I'm going to run blend for atleast 12 hours and see what's what
Thanks for the help though

That is why I will now be going straight to Microcenter for all my processor needs. No questions asked exchange is full of win. I had a bad chip before, couldn't get 4.5GHz stable at anything less than 1.47v, which was pretty ridiculous.

Your welcome, might wanna check out this thread first though and compare your overclocking results to others:

1.344 is below average volt for 4.7ghz...mine needed 1.40v in bios for that stable.

Christ, 4.5ghz at 1.47 is awful. Did you try tweaking other voltage settings too?

I think he's being sarcy...
But I only initially posted because I was finding it hard to get an oc stable, made sure I checked as many things as I could before making this thread, and when it crashed at stock, boy was I annoyed

Small FFT's will stress CPU the most! run that if you pass its not CPU.

My bet is on your RAm - if it fails blend its usually RAm - and with 8Gb you will need some more volts.

it was dead so let it DIEEEEEEEEEEE

Small FFTs are useless on Sandybridge, blend test with 90% available RAM is the best

I guess my i5 2500k is average.

I was happy with 4.4ghz with 1.31v.
I had a lower voltage before but I got a BSOD a few days later.
I wasn't sure if it was the CPU but the message led me to believe it was so I upped the voltage slightly.
I could push more but there really is no need to right now.

Wouldn't the voltage supplied to the CPU for stability also matter when it comes to what Motherboard you are using?

From my understanding some motherboards can get away with having an OCed CPU with much lower voltage.
