Server memory for DDR3 systems

This 8 GB registered DIMM is built for servers and workstations that require DDR3 1066 ECC memory. It adds capacity to compatible platforms without altering the existing memory architecture.

Standard voltage and registered design

The module runs at the DDR3 standard voltage of 1.5 V and uses a registered buffer to reduce electrical load on the memory controller. ECC circuitry detects and corrects single-bit errors during normal operation.

Quad-rank layout for density

The 4Rx8 organisation packs 8 GB into a single 240-pin slot, allowing higher total memory per channel where the platform supports quad-rank modules. Major-brand chips are tested for reliability before shipment.

Questions about this item

How do I install this 240-pin DDR3 RDIMM and what step is often missed?

Power down the server, open the chassis, align the notch on the 240-pin module with the slot key, press firmly until both retention clips click, then verify in BIOS that the 1.5 V registered DIMM is recognised at 1066 MHz.

What maintenance or replacement will this 8 GB 4Rx8 module need over time?

No routine maintenance is required; keep air filters clean so the 1.50 V memory stays cool, and replace the module only if system diagnostics report correctable ECC errors that exceed the platform threshold.

What limit appears first when this PC3-8500R quad-rank kit runs sustained workloads?

The memory controller's maximum supported quad-rank capacity per channel is typically reached before thermal or bandwidth limits, so confirm your server's rank-per-channel specification before adding more modules.
