Problem with stock corei7 4770k and talking with intel didnt help! - Page 3

post #21 of 40
BIOS problem/PEBKAC.
post #22 of 40
I found that the key to getting the H80i seated properly was having someone hold the rad up while seating it. The tension on the tubes was causing the block to slant and was making it hard to seat. I also started all 4 screws but didnt tighten them down all the way until all 4 were on firmly.

It is also possible that you just got a really good i5 and you got a really poor i7. Luck of the draw. I got mine to 4.4 at 1.24v and its enough for me, havent tried going higher though i may give a shot at it sometime. I was using 1.22v for a while but was getting BSOD only when using Handbrake, bumped to 1.24v and resolved the issue.

I also have an i5-4430 with stock cooler/clocking and it runs about 30 idle and 80-85 under load, but its very rare for it to hit load as i use it in a server. Considering getting another cooler for but so far the only ones i have liked are much more costly than its worth for me.

Seriously? that sounds like a terrible idea. I dont know what the upper limit is exactly but id think itd be like 1.5-1.6, and i think thats extreme, i wouldnt dare push mine over 1.4. Apologies if i misunderstand which voltage you mean...

First googled result for haswell voltage limit:

he wasn't talking about vcore, you should do some research in the haswell overclocking thread:

CPU input voltage isnt the Vcore. Vcore limit is 1.5v. CPU input voltage is the voltage supplied to the on die VRM's

You are thinking Vcore, but he is talking about CPU Input Voltage, which starts at 1.6ish and can go up to 2.0 (or higher).

OP, what do you have the uncore (some boards call it cache speed) set to? Having that set too high can cause instability that Vcore alone won't fix, you'd also need to increase Vring (sometimes called cache voltage) - you can try 1.15V safely. But the easiest thing is to just lock the max uncore speed at 36x and don't worry about it, it has a very small impact on performance.

You may also want to check out the Official Haswell Overclocking thread, lots of good info there.

FYI, the RealTemp cool down test is a stand alone test. It changes the load on the CPU by adjusting Clock Modulation throttling within the CPU. Different CPU generations react differently when this happens. If monitoring software is not aware of what's going on, it might start reporting some unusual or completely inaccurate BCLK information. The true BCLK is usually very consistent.

Interesting, to answer some questions, my vrin is 1.9, cache multiplier 39, annd everything else was stock. Even if it was just that thesoftware messing with it. It wouldnt have changed the reference clock in ranges between 87 -117mhz and on multiple trials. I ran those same tests on my i5 and reference clock was always rock solid. Btw for stock settings my cpu draws 1.117 for vcore its a tad on the high side =/ going sunday for exchange. Real temp cdt always mqkes me run prime95 it asks me for its .exe. and when running prime95 standalone I get similar results. Also whenver my cpu activity spikes my cpu temp goes with it, those oc result pictures show it in one of em bottom righ4 corner
