4930K degrading very quickly? - Page 3

post #21 of 31
Use CPUz to check the Vcore, 1.25v at load for a 4930k at 4.5Ghz is insanely low, or you have a very special chip. Check the Load Line Calibration setting to prevent so much Vdroop.
I only have a 120mm rear and top exhaust fan at 600rpm and have had no issue with VRM temps as far as i know.

Hello,

No, vcore is 1.304 and prime stable now. VID is 1.25. I think i can even lower vcore now to see how low it goes.
So all i did was to change rear fan to intake and voila prime stable and also 10 degrees C lower temps.

60C load now in prime.

its not uncommon for a chip to have a break in period if you will...some take 1 day or don't need to break in at all...some will break in over 2-4 week period...seen it myself several times no biggy at all....also could be the bios etc...after rply 5-10 saves or setting changes either clear the cmos or reset to default and redo settings to ensure no settings are an issue.

those voltage and heat are no where near unnatural degrader levels.

Aren't you the Degradation Apologist guy? The one who claims that there is no such thing as Degradation etc alongwith your best buddy Belial?

Sandy and Ivy do tend to degrade immediately, then stabilize, unless excessive voltages/temps are run.

Then I repositioned the front two 140 mm fans in my air 540 case to lower position by drilling new holes to improve GPU cooling.

It is after that prime started crashing. And this now leads me to believe that VRM is throttling due to no air flow at upper half of case due to reposition of fans and HC110 instead of Noctua air cooler before.

All evidence point to this. Throttling VRM could cause prime errors. And one thing more is that when I raised VCC and VTT volt prime crashed immediately. Meaning even more heat on VRM.

So fingers crossed, tonights gonna be exciting when I get home and put a fan blowing on the VRM.

Could well be a VRM issue.

One of the big mistakes people make when transitioning away from air cooling is not ensuring good VRM air flow. An air cooled CPU, even when cooling is provided by a tower cooler, usually moves quite a bit of air around the VRM. You need to compensate for this loss.

The top fans of my case are both intake, and blow air directly over my board's VRM and system memory.

Are your top fans mounted to a radiator? I choose exhaust on my top fans because they are fitted to a H110
post #27 of 31
I have found that with my RIVE and 3930K (24/7 OC of 4.9Ghz 1.355v, 1.1625v VTT1/VCCSA), and 4x4GB Ripjaws Z 2133C9 (Hynix BFR) @ 2540 9-12-10, it is pretty easy tokkeep the VRM area around the socket on the "front" side of the board cool. Just with the air passing through (one of my rads, a 420 with P-P, sits right above exhausting air), I found using my Fluke IR thermometer that I was keeping them below 60C.
The first thing I did, tho, was swap out the rear fan for a high pressure and airflow fan, and I have the rear case fan as an intake, not exhaust.
This one little thing dropped VRM Temps by 4-8C, and coincidentally, thanks to the impeccable design of HK backplates, my 670FTW dropped about 3C.

Once I really started pushing 5Ghz+ clocks, tho, I found that the VRM's were hot even with 450cfm focused directly on them.

This led me to realize that the issue is on the backside of the board. The VRM section back there gets no airflow, causing big problems with stability when you really push things.

I have yet to mill a custom 1pc copper heatsink, but just using some EnzoTech C110 heatsinks attached with 18W/mK thermal tape (brain fart on thename!), and then using a 120v AC powered server fan (forged aluminum housing, forged blades with 0 flex, dual motor, up to 4850rpm pushing 188cfm at 38.5mmH2O, about 120x120x48mm) a foot away from the case, and with the back panel off, I absolutely demolished the temp issue!
Results:
Rear VRM - dropped 31-40C
Front VRM's - dropped 8-11C
CPU Temp - dropped an average of 7.8C!

I have yet to stop using the setup, it works incredibly well! Try something similar, it just might be what's needed!

Thanks for the info. Great
post #29 of 31
The back of motherboards need heatsinks, and im surprised no company has done this...

Theres enough room to place a heatsink on the whole underside of the motherboard or at least the cpu vrm and ram socket area.

If you have a large cut out near the cpu area on the motherboard try, you could mount a think 120mm fan to cool it down somewhat.

I turned the rear fan as intake and all seems fine. Going stress test. Perhaps i will check temps on backside of MB.
