Hello everyone,
TL;DR: Is it possible for a single working DDR4 2400 RAM stick to allow access to BIOS but cause the PC to cycle instantly when any boot option is selected? Or is this caused by something else? Details below:
I am really in need of some help. I am usually a lurker, and tend to find answers in other threads but I have stumbled on something irritating and I can't seem to find a definitive answer. Several weeks ago I purchased parts for a new PC build:
7700k
Aorus Xtreme 1080 Ti
Aorus Z270x Gaming - 7
GSkill Trident Z RGB 2 x 16GB DDR4 2400
1000W PSU
After a couple RMA's (MOBO, GPU fan, etc.) and weeks going by, the PC was finally able to boot properly. I finished updating all the BIOS, correct drivers, and made sure my computer was reading everything at the correct frequency. While downloading some games throughout the day, I came back and the PC was still running but with a black screen. I couldn't do anything so I ended up restarting it. I tried rebooting it a few times but the same thing would occur. There was one time it got me to the Aorus post screen but it would not allow me to get past that. So, I ended up opening up my case to try and read any stable error codes that would appear on my motherboard. After a while, the computer stopped posting, and would just C1 error (with a DRAM light) and cycle over and over.
It was time to test some stuff out. I took out my GPU, and proceeded to test my RAM sticks without it and then one at a time in the first slot. Results:
Both RAM in: Cycles without posting (C1 Error & DRAM light)
RAM #1 alone: Cycles without posting (C1 Error & DRAM light)
RAM #2 alone: Allows me to acces BIOS
Success!! Well kind of? I discovered that one of the RAM sticks was definitely faulty and I need to place ANOTHER RMA request. I repeated the same process with my GPU plugged in and the same results occurred. Here comes the part that confuses me. When I plugged in the single RAM that allowed me to get into the BIOS screen, I tried to boot up windows from my SSD and it caused my computer to cycle instantly. I also tried booting from a flash drive and that also caused my pc to cycle. I reset BIOS, CMOS, and tried everything I could but I couldn't get a different result. Why? Is it because my RAM is dual channel and only a single DDR4 2400 RAM stick will allow me to get into BIOS but not windows because it is not supported when two sticks aren't plugged in? Or is it possibly another issue with my PC (I really hope not)? I couldn't find an answer anywhere. Sorry for the long post but any help is appreciated.
