Server memory upgrade

This OWC kit supplies 64 GB of DDR3 ECC registered memory in four 16 GB modules. It runs at 1333 MHz with CL9 latency and 1.5 V. The 240-pin RDIMMs are built for Supermicro X8QB6 and X8QBE series motherboards.

Replaces Supermicro MEMDR316LSL05ER13

The kit directly substitutes the original Supermicro part number for those platforms. The upgrade is worthwhile when the existing server or workstation needs the full 64 GB capacity and registered ECC reliability for continuous workloads.

Suits X8QB6 and X8QBE owners

Builders of standard desktops or systems that require unbuffered DIMMs cannot use this memory. Buyers needing a different capacity, speed, or form factor should look elsewhere.

Questions about this item

Will the 240-pin DDR3 RDIMMs fit the DIMM slots on a Supermicro X8QB6 or X8QBE motherboard?

Yes, the kit is built for those boards and uses the standard 240-pin DDR3 registered form factor they require.

What is the correct way to populate the four 16 GB modules on a Supermicro X8QB6 or X8QBE board?

Install one module per channel following the board's silkscreen slot order; the common mistake is placing two modules in the same channel while leaving another channel empty.

When should the 1.5 V DDR3 1333 CL9 RDIMMs be replaced?

Replace them if the system logs uncorrectable ECC errors, fails memory diagnostics, or becomes unstable under load.
