Is you board a S5000XVN or S5000XVNR? You will likly need to check the mother board part number to tell. It should be displied under system management - system Information in BIOS set-up
E11034-xxx or E11030-xxx should work with the E541=0
The original S5000XVN only supports 50xx, 51xx & 53xx processors,
The refresh version added a circuit to swith the core voltage to support 52xx,& 54xx,
If you install a E5410 on an pre-refresh S5000XVN you will get a "Processor voltage mismatch detected." error.
