Question System locks up at full load - Watchdog Timer error

[mgBride]

System details:

CPU: Intel i7-7700K 4.20 GHz
MB: ASUS ROG MAXIMUS IX CODE
RAM: Corsair Vengeance DDR4 2133MHz (4x16 Gb)
GPU: ASUS STRIX GTX 2080
SSD: Intel 600p Series 512 Gb
HD: Seagate 2 Tb BarraCuda
PSU: Corsair HX1000i Modular
Cooling: Corsair H115i Liquid CPU Cooler
Case: Corsair Carbide 400C ATX

This system was originally built with 32 Gb RAM and an EVGA GTX 1080 - it worked very well for a couple of months in spring 2017... I was moved for work, and the system did not survive the trip, and would blue screen on power up.

A local shop determined that the RAM was faulty, so I bought another 32 Gb - the system would now boot, but threw a Watchdog error on full load (Corsair replaced the faulty memory, so the system now has 64 Gb).

A second local shop determined that the issue was with the GPU, so the Video Card has been replaced with a GTX 2080, but the problem persists.

Any thoughts or suggestions on where to go from here?

Thanks in advance to anyone with a suggestion!

Mike.

You can test half of your RAM in pairs for functionality/stability over the course of a few days hoping to find a marginal stick pr pair, and/or, consider upping the ram voltage, or, adopting less stringent timings when using 4 sticks...

Prime95/ blended is a good RAM test as well...
