Windows sees only 32GB of 48GB of memory.

[Guest]

I have i7 920 with EX58-UD5 motherboard. I installed 48GB of ram few months ago, and first Windows recognized all 48 GB ram fine.

Now I noticed that when I look at task manager I only have 32GB availble, and 16GB "System reserved", so I am not able to use all of my ram.

I went to BIOS and BIOS only shows 32GB RAM.

Strange thing is that it used to work, altho I did get blue screen of death's once in a while, and now my system seems to be stable so perhaps this is the reason? Offcouse I prefer stable system and 32GB RAM.

Now my question is, that is there any way for me to still to try to get Windows to use all 48gb ram?

It's interesting though as both Intel and Gigabyte specify maximum 24 GB for i7-920 and motherboard:

I would say to leave it as it is.

I guess that you are right, perhaps I should just leave it as it is - it is still 8GB more than officially supported and I might be fine with 32GB RAM.

Have you checked for a bios update?

There is one newer update available, but this update didn't have any improvement over memory compatibility, so I didnt't bother.
