I've checked your service tag and memory part# is:-
It is recommended for you to purchase the same type of memory for the upgrade, therefore part# 9J5WF is not suitable if you are running on Optimizer Mode.
Once again sorry for the inconvenience caused.
Thanks Manfred for confirming. Just for curios iam asking. If we insert the oter part number RAM what will happen to Server? will not boot? or BSOD?
You are welcome, Akther.
Sorry for the delay, basically part# 9J5WF x8 memory module is not supported in Optimizer mode only. Most likely it will allows you to boot the server but you may encounter error messages like:-
Unsupported DIMM detected. The following DIMM has been disabled: x
Unused memory detected. DIMM’s installed in the following slot are not available when in mirror or 128-bit advanced ECC modes: x,x,x
That said, this part is supported in Memory Mirroring and Advanced ECC mode.
