PHS-memory RAM passend für Fujitsu D3644-B

This 4GB RAM is 100% compatible with Fujitsu D3644-B. What should be considered when upgrading RAM? The fast dual channel mode operation is optimally supported with paired installation of the memory. If you are using a Core i5 or Core i7 processor, you can only use UDIMM memory. If you are using a Xeon processor, you can use either ECC UDIMM memory or UDIMM memory without ECC. The ECC function is only supported if all installed memory modules are UDIMM ECC memory.
