Hi there,
We are experiencing some issues with the RAM in a set of Dell C1100 servers we have here.
Firstly, I should note that we do run a number of these machine with perfect success at the moment, containing either single or dual L5520 processors and 16GB or 32GB RAM respectively - no issues here.
The problem is with the servers we have containing dual X5550 processors. These machines only seem to see some of the RAM, not the full 64GB as desired. One unit we have shows 36GB rather than 64GB, and another is showing 49GB rather than 64GB.
We took out some of the RAM in the server showing 36GB rather than 64GB, leaving just 24GB, which shows in BIOS at 12GB (half). With 48GB installed, it shows as 24GB (half again). We then added more RAM, taking it to 72GB, which shows as 49GB (not half) - there doesn't seem to be a clear pattern.
Can anyone recommend anything to check / do in rectifying this issue? We have tried adjusting the RAM mode from independent to mirrored etc, to no avail.
Any help would be appreciated.
Thanks, Matt.
