Server DDR3 ECC RDIMM kit

This A-Tech 64GB kit contains two 32GB DDR3 1333 MHz registered DIMMs built for servers and workstations. Each module uses a 4Rx4 quad-rank layout with ECC error correction and runs at the standard 1.5V DDR3 voltage. The 240-pin form factor fits DDR3 RDIMM slots in compatible enterprise platforms.

Quad-rank 4Rx4 registered design

The 4Rx4 organisation is the single specification that determines whether this kit will work in a given system. Many server boards limit the number of quad-rank modules per channel or require specific slot population rules. Verify the platform's qualified vendor list and maximum rank-per-channel allowance before ordering.

Dual-channel matched pair

The two modules are packaged as a tested dual-channel kit so the memory controller can interleave accesses across both DIMMs. This configuration increases sustained bandwidth compared with a single 64GB module and simplifies installation by guaranteeing matched timing and voltage characteristics.

Questions about this item

How much total memory does the 64GB kit add to a compatible server?

The kit provides 64GB total across two 32GB modules, doubling the capacity of a single-module upgrade.

What does PC3-10600R mean for actual bandwidth on a DDR3 1333 platform?

PC3-10600R indicates a peak transfer rate of 10600 MB/s per module at 1333 MHz, limited by the DDR3 bus and registered buffer.

Will these 240-pin DIMMs fit a standard DDR3 server memory slot?

Yes, the 240-pin DDR3 DIMM form factor matches registered DDR3 server slots; desktop and laptop SO-DIMM slots are not compatible.
