Hello
I have 2x2GB HP UDIMM replaced with 1x 16GB Kingston KVR16R11D4/16 RDIMM.
BIOS detects full 16GB, but Win Server 2008 R2 HPC has only 8GB, other half is 'hardware reserved' in perfmon.
Memory mode is "advanced ecc", already tried another options and speeds.
The processor is QuadCore Intel Xeon E5606.
I didn't find an 'Online Spare Memory' option in my BIOS, as it was stated in neighbour topic.
How can I use all 16GB in Windows?
