I own an ++HP Obelisk Desktop 875-0034++ gaming ***desktop***.
I first tried installing a 2nd 16 GB RAM stick (Kingston) and, for a few days, every was fine. Then, my desktop began to freeze at random intervals and I had to forcefully restart the desktop to get it working. Once I removed the Kingston RAM stick, everything worked like normal.
I tried swapping the RAM sticks between the RAM slots and the issue still occurred; but when I insert the RAM stick that came with the desktop, no issues occurred so ***I don't think the RAM slots are bad***.
For my 2nd attempt, I completely replaced the RAM that came with the desktop with ++2 (Corsair) 16GB RAM sticks (totaling 32 GB)++, and the same issue occurred. Worked for a few days, then random freezing occurred.
The motherboard is an ***Edoras*** so ++BIOS doesn't show Advanced Options or XPM++.
HP PC Hardware Diagnostics Windows, HP Support Assistant, and the built-in Diagnostic software have all indicated that there are "No Problems" which is obviously wrong. And HP Support Assistant says the BIOS is up-to-date.
There's no pending updates under Settings, Device Manager says the drivers are current, and neither Corsair nor Kingston offer drivers updates on their websites (not since I last checked).
And apparently, there are ***no manuals/spec documents ANYWHERE on the internet*** and HP hasn't been helpful at all.
* The PC is 64-bit and both RAMs are compatible.
* It is up to date, and uses Windows 11.
* Both RAMs are 16384 MB
* Both RAMs are 2666 MHz
* Both RAMs are DDR4
My only remaining option is to try a single 32GB RAM stick, but I'd rather not risk losing another $70+ if I'm gonna end up with the same issue.
