Hi,

[disclaimer] I'm finnish, so sorry for bad english [/disclaimer]

 

I have this PC with originally 8GB (4x2GB) of ram, but something happened couple of days ago, and show only 4GB of ram now. Bios shows always only 4GB and memtest same total, but still that all slots have 2GB sticks. Windows show randomly that installed memory is 8GB, but only 4GB usable.

I have ran memtest (3 passes 0 errors), swapped stick slots, take all sticks off and put back 1 by 1 (1 stick -> 2GB, 2 sticks -> 4GB, 3 sticks -> 4GB, 4 sticks -> 4GB).

Also updated BIOS to P01.B2, but it didn't do anything.

 

What to do next? I dont know what it could be. Googled for hours, but nothing seem to work.
