5820k overclock

Which thermal paste do you suggest? The temperatures with this heatsink how should be?

With your cooler, you shouldn't be getting more than 70C ( worst case scenario).

As for thermal paste, i use noctua nt h1, which i find really good, but IC diamond and mx4 are also good.

Assuming your fans are running properly and not automatically set to silent or something (you NEED to check this in the fan control tab), you should be getting in the 60s max. Low 70s is bad, high 70s and 80s is unacceptable for that cooler.

 

I use noctua NT-H1 but literally almost any thermal paste will preform basically identical to each other.

My fans are connected directly to the power supply and run 100%. My temperature on full load is higher than 70

Direct to the power supply? ok, then yea... 70 is the absolute max I would accept given that cooler, and 83 is so far beyond the reasonable realm of cooling, I would highly recommend remounting...

Ok thank you for the help. Does an expensive thermal paste make the difference or can I buy one for few money?

Not really, I would expect a decent one to cost you like 5-10 USD that's it. And you can use it 10-50 times.

 

I don't recommend getting random no-names that are like a dollar or two.

 

Against NH-T1 is a good easy choice. Costs like 7 usd. http://www.amazon.com/Noctua-NT-H1-Thermal-Compound-Retail/dp/B002CQU14A/ref=sr_1_1?s=electronics&ie=UTF8&qid=1452120545&sr=1-1&keywords=nt-h1

Ok I go with noctua and I'll reopen this topic when I have changed the thermal compound.

Not all chips are equal, but haswell is literally the most equal chip architecture ever made, and I had before today never encountered someone who couldn't get 45 @ 1.3 stable on a chip that wasn't pre-q2 2015. And now his temps are WAY HIGHER than they should be, ofc I tend to think it's a different issue.

Is there really that big of a difference in 5820Ks pre and post Q2'15? I have a 5820K from Q4'14, and can't hit 4.5 on any voltage. Do you know what changed? I'll be a super sad panda if nothing changed an all of the chips power Q2'15 are just that much better.

 

Side note, my 24/7 OC is 4.3 GHz at 1.272 volts.

Intel got its yields and quality up (think like significantly lower asic on average at release compared to now). Honestly that's something that happens with literally every generation of chips (haswell refresh is the embodiment of this set even as they improved the fivr and tim). I don't know exactly when it changed, and there wasn't a discrete swap but basically pre-production chips (those that had to have started before Haswell-E or near it's release) are definitely inferior.

 

Consider how many reviewers talked about the "badness" of their chips and then come to realize there it totally a pattern, because those must have been very early samples.

 

Additionally I don't know if you remember the launch pattern, but for some reason intel rushed the fuck out of x99. Like aib's were bitching left and right that they didn't have enough time and that intel still didn't have the x99 chipset down properly.

 

Speaking of which, it is entirely possible that not only are early chips inferior but early editions of the motherboards are likely less capable as well regardless of software updates.

[RazrLeaf]

Hm...TIL.  Guess that's what happens when you're an early adopter. 

 

The funny thing is, I only went Haswell-E/X99 for the DDR4. I'd just finished school, and figured that if I'm going to be building my own PCs, I'd start on X99 so I never have to deal with DDR3.

When did you have the blue screen? Because seriously... if you are properly mounted and cooled, maybe 1/500 (not real stat, but I've never heard of one) recently purchased 5820k's can't hit those levels.

 

I tried mine at 45 and 1.3 and it wouldn't pass a benchmark. 44 seems to be my max but I run it at 4 ghz 1.15volts for 24/7 use. My xmp was off. Temps were not the issue because at 1.3 volts I only hit 60c with my 360 Predator.

Edit: I got my Cpu 11-2015

This is now the second time I have ever heard of one (although I don't know if you or the other person tried adjusting vccin, which is an important consideration). But the 44x 1.3V was what I was talking about with 1/500 max.

Didn't touch the vccin so maybe ill look back into it. I took a long break from pcs trying to get back up to speed.

Yea setting vccin to like 1.95 is a generally recommended setup. Generally it isn't needed until above 4.5/4.6, but it could be an issue for me.

 

It was literally impossible for me to hit 4.6 at any voltage until I upped my Vccin.

What would be the max Vccin?

Well Asus doesn't recommend over 2.1 (according to the sabertooth bios which has color labels on "safe", "warning", "don't do this"), but I would personally stay south of 2V.
