I have a Lenovo D20 Thinkstation.
I had 2 Xeon 5550 CPU installed, with 48GB of ram of 8GB sticks.
I replaced the 5550's with 2 Xeon 5690's. Hardware reserved memory jumped from zero (if I remember correctly) to 16GB.
I've tried every solution I could find here and elsewhere to reduce/eliminate that reserved memory to no avail.
I'm baffled. Why would changing the CPU have such an effect? I might be missing some obscure hardware fact.
Is it possible I introduced HW damage somewhere?
Is there some corner case solution I should try? What would that be?
Some info about the system (from System Info):
Installed physical memory: 48GB
Total physical memory: 32GB
BIOS Version/Date: Lenovo 61KT48AUS, 5/19/2011
OS: Windows 7 Professional
Version: 6.1.7601 SP 1 Build 7601
There is a BIOS update available but I'm afraid to upgrade it. Should I do it? Is it relevant?
Help is much appreciated.
