Now, that's some serious power you got there!

Your issue smells like mobo can't train the memory good enough.

Although I always hate assuming, I'll try it once more - assuming you know how to build properly after that truckload of $$$ spent, I'll take your RAM, cabling and CPU are seated correctly.

With the above said, I'd reccomend leaving just 1 stick of RAM in A2, clearing CMOS and trying to boot. If my theory is correct your WS should boot right off.]]> Sat, 16 Feb 2019 23:37:52 +0000 https://forum.asrock.com/forum_posts.asp?TID=10898&PID=60762&title=very-odd-boot-behavior-on-three-identical-builds#60762 https://forum.asrock.com/forum_posts.asp?TID=10898&PID=60730&title=very-odd-boot-behavior-on-three-identical-builds#60730 Author: jawknee530

This last week i built three identical builds.

Threadripper 2990WX
ASRock X399 Taichi sTR4 : 3.30 Bios
G.SKILL Trident Z RGB (For AMD) 32GB F4-3200C14Q-32GTZRX: 3200 14-14-14-34 XMP
EVGA SuperNOVA 1300 G2
SAMSUNG 970 EVO
Dual Nvidia Quadro P1000s in PCIe slots 1 and 4 (the 2 x16 slots)
The odd issue is that every time I boot any of the three machines after they've lost access to power it takes three tries.

1st: lights come on, fans spin up, then it cuts off after just a few seconds

2nd: everything comes up, Dr Debug starts cycling through it's thing, then everything cuts off after maybe 15 seconds

3rd: boots properly

This only happens after a fully cold boot where the machines has been unplugged or the psu switch has been flipped off. The machines all boot normally after this first little dance. This happens wether the ram is at 2133 stock or under the XMP profile at 3200.

BIOS Settings:

CPU at stock frequency and voltages
SMT disabled
Precision Boos Overdrive disabled
SVM Mode disabled
IOMMU disabled
All other settings default
I get the same behavior regardless of these settings, these are just the current ones.]]> Fri, 15 Feb 2019 11:49:38 +0000 https://forum.asrock.com/forum_posts.asp?TID=10898&PID=60730&title=very-odd-boot-behavior-on-three-identical-builds#60730
