3930K Memory Controller problem (possible solutions?) - Page 3

That depends on the TIM you are using.

i use plain old idle, (fresh reboot) and prime95, AFTER a 5min timer or 10 min, depending on what I need to check.


keep in mind that after new TIM has been applied it can take up to almost 100 hours or so to reach its full ability the checmial process of breaking the TIM down or however it works, it needs to be heated and cooled a few times over the break in period (some people say it dont matter)

you will see a few degree drop at idle and load in about 1-2 weeks though after a fresh application

Thanks for mentioning this!

I just purchased some Arctic Silver 5 and was reading that the paste needs to get broken in for 200 hours worth of heat up/ cool downs. Good to hear this repeated so I know they're not blowing smoke.

I guess i'll take it easy on the overclocking until next month, just so i don't burn anything out by accident. Praying to God I can get it back to at least 4.8GHz b/c that was some serious performance I was getting in my music DAW. Gonna dial it down to like 3.8GHz or something low (i can't believe that's LOW!!!... I used to be happy to get 3.8GHz on my AMD Phenom II 955 lol) until it's cooked in good.

So I ended up buying 3 thermal pastes lol... in case one worked better than the other (and since they are cheap).

I grabbed Tuniq TX4, Arctic Silver 5, and Prolimatech PRO-PK1

The reviews seemed to lean in favor of Tuniq, so I went straight to that. Carefully cleaned off the CPU and the heatsink w/ coffee filter dipped in 70% alcohol. Think I got everything up well.

I fired up everything after letting it dry for a few mins. I can definitely see the improvement w/ new thermal paste! This thing looks like it runs much cooler on average. I got up to 4.6GHz stable. Cut it back to 4.5GHz for satefy reasons. I'll post up my temps later, my internet connection wasn't working on that computer for some reason.

It's not the 4.8GHz overclock I had previously gotten... so i'm still slightly bummed (very slightly).... so i'm wondering if I may have not applied the thermal paste as perfectly as the stock paste was applied. The stock paste came with a glob on the heatsink and it spread by smushing it. 4.8GHz overclock was no problem... even considering the fact that I had first put the heatsink on the 3820 and THEN on the 3930K, so it had already been smeared by the first time it touched the 3930K and still rendered a 4.8GHz clock speed. When I applied the paste this time... i tried to follow the less is more strategy and not glob it all over the place... but when i spread it, it didn't spread very evenly. I got a coating... but some parts were showing a little bit. Good or bad?


Do you guys think I should clean it up and try one more time by letting the heatsink spread it? Also... should I break open the Arctic SIlver or the Prolimatech bottles I got?

Or am I seriously just splitting hairs here and should just be happy w/ 4.5GHz? lol



also note:: at first, i had the heatsink on too tight again.... and 4.5GHz was crashing. I loosened up the screws and it's now stable. not sure if that plays a factor in if i applied the paste well or not, but figured i'd mention that.

Couldnt see which heatsink you have? but odd that its causing issues when tightened fully.

What settings are you using for 4.8Ghz/4.5Ghz? TIM application is not causing a 300MHz loss of speed at same settings. Problem is elsewhere, most likely you had changed something before you reset CMOS and now havent.

^Antec Kuhler 620.

At the moment I'm using the Auto settings. I don't know what I'm doing fully (besides some basic things anyone can google and read), so i opted to keep the voltages/etc of the CPU on Auto. I believe the other changes in the BIOS that I made were just related to turning off SpeedStep and things of that nature... but I will have to double check.

There's a chance you're right... b/c when I load up to 4.5GHz, the temps remain in the mid 40C's if i remember corrcetyl... and only get as high as mid 50C, low 60C when processing something heavy. The max values would peak around 70C when doing things like loading Win 7, open/closing a large project and forcing it to calculate everything at once in a short period of time.

Not sure if that is normal or not. I'm going to try to post the temps today so I can show the hard data instead of trying to go from memory.

Okay finally.... here's new temps w/ a full loaded project



I'm confident the general temps are fine... i'm mainly worried about the max temps. are those too high? they maxed that high only for a few split secs when loading up the project.. or things of tht nature. but running the project seems to say cool.

should i be worried about temps spiking?
post #27 of 31
could be that now that its using all the memory the chips imc just cant handle that high of an overclock anymore.

^hhhhmmmmm... wait a sec.... so you're saying it could be the RAM that's failing and NOT the CPU? (I had to read your comment like 3 times on separate days before I got it lmao)


That would make total sense!!!!!!! B/c the temps just don't seem hot enough to be the issue.... so maybe my RAM is acting unstable. I got a few random crashes watching video and things of that nature.... stuff that I wouldn't have thought would cause a crash.

Thanks for the tip... i'll test it out.

And tadaa.. 4.8ghz overclock is back! Thanks so much man. Looks like my ram was unstable. System seems to be acting much more stable. Thanks so much... didn't realize my ram overclock could be a culprit

When stress testing I would recommend using a program like prime 95. Custom blend this will show you temps when the cpu is at 100percent load and the worst case scenario. If it doesn't bsod and temps don't get too high you know you are safe and have a stable overclock. Using a program that only stresses the cpu and ram to say 70percent will not give you max temps or test the overclock properly. It will tell you if the overclock is stable at 70percent load not 100percent. For long term stability and piece of mind prime 95 is the way too go. :-) then if it is stable you know that any program's or applications you are running will not cause any problems long term.
