Upgrade with a 483403-B21 HP 8GB PC2-5300 240-PIN DDR2-667 ECC REG RAM 2x 4GB module kit option
If your looking for the 483403-B21 HP 8GB PC2-5300 240-PIN DDR2-667 ECC REG RAM 2x 4GB module kit option, PRO Memory Upgrade delivers. HP builds computers but does not make memory, they buy from the same DRAM, suppliers we do. Install factory original RDIMM 483403-B21 modules made by Samsung, Hynix, Micron and Qimonda, the same as HP does when building new ProLiant servers. HP sells these same RAM options just like us, but at much higher prices the only difference is HP label.
