My Ram disappeared after 6years of greatness

Hi,

I tried on Tom's Hardware French but got no success so I'm retrying here. I've had a heavy duty, rendering, period in the past few weeks and my PSU for ten years didn't appreciate it, causing a few impromptued shutdowns. It had several slightly bulged capacitors. I replaced it since then and now have a v550 from cooler master. But before that during the rendering period, half my RAM disappeared. I went from 32GB of DDR3 (4x8GB of Gskill 1333MHz) to 16GB causing crashes.

I've tried memtest86 and got no error. Same with windows memory utility test (or something like that). I booted with only one stick and tried each of them. I then tried switching slots. I reset my CMOS (I think).

I then used an other set of memory a 2GB and a 4GB stick from corsair (same reference) from an other computer and noticed that depending on with ports are populated my MB detected either 4GB or 2Gb but never managed to get 6GB.

Can anyone help me?

I read that it could be due to auto settings in the bios but couldn't solve this by myself.

My config :

I7 2700k back at 3,50 GHz
MSI Z77A-G45
4 x 8GB 1333MHz Gskill
MSI GTX 970 TwinFrz
CoolerMaster v550 PSU 80+Gold

No before I change the PSU, during the heavy duty period.

The motherboard doesn't seem to be damaged, I repasted the cpu with Noctua 's paste. Tested each stick of RAM. Tested each slot moving the same stick.

In the original post I mentionned that I reset the CMOS (pull the battery away for 2hours, pressed the reset CMOS button).

Did that not reset settings to default?

The BIOS displays either 2GB or 4GB, apparently depending on slots selection.
