New Build Crashed under CPU Load

[Airalith]

Hi all,

I have finished putting together by new X99 build and am experiencing crashes when under load. It has been some time since I have built a PC and have never had issues in the past, so I want to sanity check my fault checking if possible because its quite possible I am making a schoolboy error here.

My build is as follows:

Asus Rampage V Extreme USB 3.1 Intel X99 (Socket 2011) DDR4 EATX Motherboard MB-640-AS

Intel i7-5820K 3.30GHz (Haswell-E) Socket LGA2011-V3 Processor

Corsair Vengeance 16GB (4x4GB) DDR4 PC4-24000C15 3000MHz Quad Channel Kit

EVGA Supernova G2 650W '80 Plus Gold' Modular Power Supply

Raijintek Triton Core Edition AIO Water Cooling Solution

Build boots into windows fine and has no problems when at idle or minimal working (internet browsing and such). When under load (games or CPU stress testing under AIDA64) I experience freezing (no blue screen) forcing a restart.

AIDA64 dies anywhere between 2 - 8 minutes but my temps go no higher than 55c.

I have also attempted to use memtest86 to check for memory problems but this dies (froze and did not recover) whilst checking CPU Cache.

Everything is at stock currently and I am running the latest BIOS.

Truth be told I lean into the CPU being FUBAR and unless anyone can offer some suggestions I'm in a mind to RMA. Any thoughts/opinions would be greatly appreciated.

I doubt its CPU, more likely memory crapping out due to not enough memory controller voltage

Any bsod? Usually it's 0X000000124 or 0X000000101 if its memory controller voltage not enough

No bsod as yet under any conditions. Do you think it is worth me manually upping voltage on the memory and testing again? Everything is at default atm as I've not even been into the BIOS.

Are you on latest BIOS version?

Tested with and without xmp enabled for the memory

Yep on latest BIOS. I've not touch XMP profiles as yet, worth turning it on and testing again you think?

Could try,but if anything it should be more stable without xmp

Xmp will set the memory to full speed, but it won't adjust memory controller voltage

I thought that was how it worked, hence I didn't touch XMP. Would you say manually upping the memory controller voltage is worth a try or would this be a bad idea?
