Hitting a overclock "wall"

post #1 of 5
Thread Starter 
has anyone experienced that with their CPUs?

my i7 920 stopped at 3.8ghz with 1.275v and it took over 1.34 to get it stable at 4ghz. my i7 930 got it to 4ghz with only 1.265v and it took over 1.35 to get it stable at 4.2ghz. thats a huge jump just get that extra .2

i stopped it at that because it just didnt feel efficient to me.

my old E8400 went to 4ghz on air so easy with almost stock voltage.
i guess they all cant be golden.

happened to anyone else?

Well my old E5200 hit 4Ghz with 1.3V, and now with that one fried, my E5300 can't hit 4Ghz with 1.45v :/

Without question, there's a point where the uphill battle gets steeper and steeper.

I've experienced this with both the i7's I've owned, though I can assure you it's not specific to the i7. The further you push hardware past what it's meant to run at, the more juice you'll need (and not just the processor / vcore, other voltages on the motherboard will start to need adjusting to compensate)

Also keep in mind however that all cpu's are *not* created equal, so if someone hits 4.4ghz with only 1.30v, it doesn't mean that you'll necessarily be able to do the same or come close with yours.

Best thing to do is pretty much what you've already done, find the sweet spot where it's got a nice boost in speed while still being efficient and not putting too much strain on the cpu for the extra 200mhz.

I got 3800 with only 1.23V, 4250 with 1.36V, and for 4300 I needed 1.40V.

It gets very steep as you start reaching the "wall"
