    Question Computer rebooting semi-randomly under GPU load - am I taking the right steps?

    Swapped out the PSU today - been testing a lot - 2 hours in Furmark, and plenty of games... The problem seems completely resolved. Still very stable - today it was very hot in the room and the computer is still perfectly stable. Guess I'll be sending in the old PSU when I can (still under...

    Question Computer rebooting semi-randomly under GPU load - am I taking the right steps?

    Thanks for the response! My drives include 1 SATA M.2 drive, and a full load of SATA non M.2 drives - SSD & HDD. The temps on the SATA M.2 are OK, 50's to 65 max C. It doesn't have a heat spreader or anything. No indication of problems. I didn't test it super thoroughly for opening front...

    Question Computer rebooting semi-randomly under GPU load - am I taking the right steps?

    Now my build is over a year old, but I think this is the appropriate forum for this kind of problem... tldr: Computer reboots under intensive GPU loads - despite how long the load has been running, and very predictably upon certain interactions from user. Examples: Example 1: Doing something...

    Discussion After new BIOS install, RAM frequency affects bandwidth or power to onboard audio and USB

    I finally solved my issue thanks to a clever user on the Asus forum. Something I did not know, upping RAM frequency, even if you don't touch DRAM voltage, WILL UP VCCIO & VCCSA (system agent) voltage if you have them on any auto / adaptive setting. If you don't have those two voltages locked...

    Discussion After new BIOS install, RAM frequency affects bandwidth or power to onboard audio and USB

    A new BIOS came out a few days ago. I updated. Same issue. What I have found, though, is if I up my PCH voltage I can mitigate the problems caused by the RAM frequency. Again my problems are tied to RAM FREQUENCY, not RAM voltage. Unless more voltages go into RAM frequency than just DRAM...

    Discussion After new BIOS install, RAM frequency affects bandwidth or power to onboard audio and USB

    Hi George P, First, thank you for your well thought out reply. However, I'm aware of the rushed nature of the Spectre fix, and I know that's what's causing my problems. What I really wished to find was the root (technical) reason I may be suffering such problems and/or something I could...

    Discussion After new BIOS install, RAM frequency affects bandwidth or power to onboard audio and USB

    My PSU is the EVGA SuperNOVA 650 GS (650W). The amps on +5Vsb is 2.5A. Why do you think they would break the power management in the new BIOS? It worked fine earlier in the day before I installed the BIOS.

    Discussion After new BIOS install, RAM frequency affects bandwidth or power to onboard audio and USB

    My motherboard is the Asus Z170-A. For over a year I was using BIOS 2202 with no problems. I could run my RAM at 3000MHz without issue, perfectly stable. I used the XMP profile which set the DRAM voltage to 1.35v. I also overclock my CPU but that has no part in this story. When I updated to...
