Hardware Error when RAM is around 80%

Symptoms
- Caps Lock Light Keeps blinking
- System Freezes at RAM Level is around 80%
- No entry in Logs
- Recent RAM Change
- Recent BIOS Update
- Hibernation Enabled *
- zram Disabled
- BTRFS File System
- zswap disabled using kernel parameters

Recently I upgraded my RAM from 16GB to 32GB, I also did some research and found out that Caps Lock Flashing means that it's a Hardware Error / BIOS error (I also upgraded my bios), While Checking the system logs, i found nothing like the logs stop at the exact moment the system freezes and the next entry is for a new boot (coz i am forced to manually restart every time this happens)

* I Enabled hibernation because I have a dual boot and I hibernate the system when I need to switch to Windows

Plus few months back I had some crashing problems at random intervals, so I posted about it [here](https://bbs.archlinux.org/viewtopic.php?id=294836) and I was suggested to disable zswap around the same time I also switched to the lts kernel and it solved that problem (i don't know what worked, disabling zswap or switching to lts ) but now i have this.

Re: Hardware Error when RAM is around 80%

Sounds like you have issue with your RAM.
Maybe it is defect or the new RAM does not match to the existing one.
Investigate here by
- removing the new RAM, use only the old one
- use only the new RAM
- change RAM slots

And: run a memtest, several hours to be sure:
