Hi
I am trying to upgrade my pc (Acer Aspire desktop
TC-875-UR13) memory from the current 12gb (8+4 Kingston) to 32gb (16+16
Kingston). All the memory is 2666mhz DDR4. New mem is Kingston Fury DDR4 2666
mhz. Graphics is Intel UHD 630.
Problem Statement:
With the two new 16gb memory cards installed the pc boots up
windows11 to the point where you need to click the mouse to start the login
dialog.
At this point the background wallpaper is showing correctly
on the monitor. After about 20 seconds the screen become pixelated and
flashing.
I cannot login and PC does not appear to crash. I just
cannot login or do anything. Cannot shutdown so I have to power off.
What I have tried:
1. Installed one 16gb works fine
2. Installed one 16gb plus one 8gb works fine (24gb)
3. Updated/checked all drivers
4. Removed all "pined apps" for Startup
5. Removed all unessacry apps
6. Tried a different monitor same problem
Note:
With the two 16gb memory cards installed the Bios shows 32gb.
Other than Microsoft software the only other apps are Adobe photoshop and
Chrome.
My suspicion is an addressing conflict between internal
video and main memory causing corruption. Or an app is clobbering it
Has anyone else encountered this problem? Any thoughts on
what might be happening?
