duallies & different RAM

post #1 of 6
Thread Starter 
I have a question regarding dual socket set-ups & RAM..

Say I have a dual s1366 mobo..same CPUs.. can I put RAM kit type 'A' in slots for CPU1 & RAM kit type 'B' in slots for CPU2?

ie:

CPU1 (say Xeon E5640) accesses a RAM kit that is: 3x4GB DDR3-1333 REG+ECC

&

CPU2 (also a Xeon E5640) accesses a RAM kit that is: 3x4GB DDR3-1333 unbuffered / non-registered ECC

possible? redface.gif

Depends on the board really.

I just built a workstation that has dual CPUs. I mismatched the RAM to death. I have mixed brands, speeds, and ECC.

Works just fine.

should work fine (only the memory controller on the CPU talks to the RAM anyway), only issue you might come across is if the board BIOS throws a wobbler when it reports the memory types installed.

 

Personally I'm not sure I'd risk it, but you can always try it and see what happens...

Bios throwing a wobbler, That's a good one, +rep for giggling.

It's older. It's a Dell Precision 490. It's DDR2, unsure about the processors some type of Xeons. Was made for XP though.
