I have DX58SO with the latest BIOS (5600) and X5650.
The problem is that I can not set the Performance Memory Profiles in Memory configuration.
If I do, the system can not boot and goes back to default.
I could change the memory settings without any issues through Intel Desktop Control Center, though. I noticed that the uncore voltage is hidden in the bus speed section in Intel Desktop Control Center and in Intel Extreme Tuning Utility.
So I think that the problem is that I see that option in the BIOS, and if I set it, I could not boot.
Is it possible to change the uncore for my xeon?
If so, how?
