64GB DDR3 1066 ECC RDIMM Kit

This 64GB kit contains eight 8GB DDR3 1066 modules built to the PC3-8500 standard. Each stick is a registered ECC DIMM with a 4Rx8 quad-rank layout and operates at the standard 1.5V. The memory is designed exclusively for servers and workstations that require registered DDR3 DIMMs.

Registered DDR3 limits desktop use

Registered DIMMs place a register between the memory controller and the DRAM chips, which reduces electrical load on the server memory bus. This buffering means the modules will not function in standard desktop or laptop platforms that expect unbuffered memory. Compatibility is restricted to systems whose documentation explicitly lists DDR3 RDIMM support.

4Rx8 quad-rank density per module

Each 8GB module uses a 4Rx8 organisation, presenting four logical ranks to the memory controller. Servers have a finite number of rank slots per channel, so the total number of quad-rank DIMMs that can be installed is capped by the platform specification. Verify the maximum supported ranks per channel before configuring all eight modules.

Questions about this item

Should I pick this 64GB kit or a smaller DDR3 1066 ECC RDIMM option?

Choose the 64GB kit when your server or workstation has enough 240-Pin slots and the workload needs maximum capacity; a smaller kit is only sensible if slot count or budget limits you.

What does the PC3-8500R rating mean once the modules are installed?

PC3-8500R indicates a peak transfer rate of 8500 MB/s per module at 1066 MHz with registered buffering and ECC, so the system can sustain that bandwidth for server workloads.

How does the DDR3 240-Pin RDIMM interface cap performance in practice?

The DDR3 240-Pin registered DIMM interface limits speed to 1066 MHz and requires a compatible server or workstation memory controller; desktop or laptop boards will not accept these modules.
