Frequently Asked Questions

Q1: Can MTC40F2046S1RC64BH1 be used on consumer desktop motherboard?
A1: No, it is DDR5 RDIMM Registered ECC server memory. Regular desktop motherboards do not support RDIMM register memory and cannot boot with this module.

Q2: What is the difference between RDIMM and UDIMM?
A2: RDIMM has register chip for better signal integrity and supports larger memory capacity for enterprise servers. UDIMM is unregistered memory commonly used for desktop and entry workstations.

Q3: Can I mix different rank or different PN memory in one server?
A3: Not recommended. Mixing different rank or PN may lead to memory frequency drop or system instability. It’s better to install same PN and same rank memory in the memory channels.

Q4: Does ECC RDIMM improve gaming performance?
A4: No. ECC is designed for data error correction and system stability, not for gaming acceleration. It is not suitable for gaming PCs.
