Update on my Hyper EVO cooler. I decided to see if maybe the middle tension screw on X bracket would add any more pressure to the seating of the cooler, so I was able to tighten it with my fingers quite a bit until it resisted. I noticed some comments on the internet saying that middle screw does nothing, but it seemed to tighten for me. As usual instructions are junk on this cooler and there is no mention of this screw to tighten it.

Since that adjustment, I am seeing temps at load (Prime95 after hour+ run) of 56C versus the prior 65C so its a definite improvement. I will run it now for 5-6 hours and check back on temps.

One thing that still seems odd is that if I touch the heat pipes near the base, they are barely warm to touch. Is that normal?

Also what are others seeing for load temps at stock clock speed?

Stock temps should be pretty low, from a review I read that I cannot seem to find, they were getting 50c under load using the Intel branded closed loop system, so slightly above that makes sense for a good air cooler.

I just put a x79-ud3 and 3820 together. I setup a couple profiles. 4.3 at 1.2v ish, still need more time to try and lower it. I got the chip upto 4.8 with 1.25 strap. I ran heaven to compare to my previous setup. At 4.8 it's just a hair off, 4% or so. I would try higher but I think I've hit this chips limit. And it wants so damn much imc voltage to do anything. Btw, I hate this ud3. I expected to hate it, but did not count on it being such an annoying board. The Giga uefi is suck and the no numlock is irritating as well as no proper pwm control on the cpu fan header. What the...?

I do have to add that this is a cool running chip. At 4.8 iirc with the little time I had behind the wheel, temps didn't break 68c. My 2600k@5.3 was pushing just past 80c. lol, it's a huge relief on my 7970's now. thumb.gif


Anyways:

3820@4.8 .... 7970's@1300/1745

375

2600K@5.3 .... 7970's@1295/1745

Welp, managed to get to get 5ghz to run. Now it's just a matter of getting it stable enough to run heaven.

Played around with my 4.8 overclock got my ram to 2066 and voltage to 1.315 stable.
I got my voltage pretty far down from 1.365 I don't even know if it's worth going any lower than 1.315 because it's so cold, stable and it's within Intel's recommend wattage range and that's being clocked to 4.8ghz.

It seems like I'm good to go here but I haven't checked to see what others have got their voltage to so I figured I would check to see if this is a decent voltage range for a 4.8ghz overclock?
410
Any thoughts?
post #749 of 6491
Yes, it's an awesome voltage. Have you run Prime95?

Yeah I've been running prime on it for about an hour switching the test every 30 minutes or so. Ran the MAX FPU and Max heat test so far. going to test the blend now.
