RAM slot failure all of a sudden...

MegaloGamiac · September 19, 2019

So i built my new machine about 8 weeks ago. I'm Using a Gigabyte x570 aorus pro, a 3700x and 32gb or Kingston HyperX Predator RGB 3200 cas 16 and aside from some early issues with the XMP profiles (Which was fixed by a bios update) i have had no problems until today. Today i attempted to boot up my PC and it wouldn't post. I restarted it and tried again still with no luck so i took a look inside and saw the light was stuck on RAM telling me it was having issues loading. it usually cycles past that pretty quickly. After many failed attempts at letting it do its own thing i began to remove dimms from the board leaving a solitary 8gb dimm in the 1st slot. booted fine and everything worked, i then populated dimm 2 and everything works, same with 3 but as soon as i populate dimm 4 it sticks on the boot and i cant even get to bios, just nothing except all fans going at max continuously like its stuck on the boot cycle or something. i thought it might be a problematic RAM stick so i switched that dimm with one in another slot left the 4th one unpopulated and it posts. i populate dimm 4 and nothing. This has led me to believe i may need to RMA my motherboard but i am at a complete loss as to what may have caused this in the first place so i can avoid this issue in the future.

Any insight into this would be amazing as i'm not entirely sure my diagnosis is correct (i'm not anything close to an expert)

Thanks in advance for anyone willing to help

You could try...

Clearing the cmos
Rolling back to an older BIOS

...other than that it's going to be a bad board or bad CPU

Truth be told I had the WIFI version of that board and the BIOS never became stable for me so I swapped it for a different brand. Had the XMP problem, and was unable to accesses the bios without removing all boot medium. Every BIOS updated made it worse.

So I think jumping back a BIOS revision might be your best bet.

thanks for the reply i have considered all you have said there and have already done a complete bios flash back to the last version and i also tried updating to the newest version too as there was a new one out a few days ago and still no luck. however you mention the possibility of a bad cpu? is there any way i can test to see if that's the issue before RMAing anything?
