32GB DDR3 1066MHz ECC RDIMM for server workloads

This 32GB registered DIMM runs at DDR3 1066MHz with PC3-8500 bandwidth and CL3 latency. It targets administrators upgrading compatible Samsung M393B4G70AM0-CF8 or M393B4G70BM0-CF8 slots in rack or tower servers that require ECC registered memory.

Sustained load stability with 4Rx4 organisation

The 4Rx4 rank layout spreads addressing across four ranks of x4 chips, reducing per-rank electrical loading during long compute jobs. ECC corrects single-bit errors on the fly while the registered buffer dampens signal noise, keeping throughput steady under continuous multi-threaded workloads.

240-pin installation requires registered DIMM

The module fits standard 240-pin DDR3 DIMM sockets but will not work in platforms that only accept unbuffered UDIMMs. Verify the system qualified-vendor list for these Samsung part numbers before purchase; mismatched rank count or missing registered support are the common reasons a module fails to POST.

Questions about this item

How much power does a 32GB DDR3 1066MHz ECC RDIMM draw at its 1.5V rating during sustained server workloads?

The module operates at the standard DDR3 voltage of 1.5V; actual power draw depends on your platform's memory controller and load, but registered DIMMs typically consume slightly more than unbuffered equivalents due to the register.

What motherboard slot and chipset support are required to run this 240-pin DDR3 1066MHz registered ECC module?

You need a server or workstation board with 240-pin DDR3 DIMM slots that explicitly supports registered ECC memory and the PC3-8500 speed grade; consumer desktop chipsets generally do not accept registered modules.

Can I mix this 4Rx4 32GB DDR3 1066MHz RDIMM with existing 2Rx4 or 1Rx4 modules in the same channel?

Mixing ranks is possible only if your system's memory controller and BIOS allow mixed-rank populations; many server platforms require identical rank configurations per channel for stability at 1066MHz.
