32GB DDR3 1066 Load Reduced DIMM

This 32GB DDR3 module runs at 1066 MT/s with a low 1.35 V supply. It uses a 240-pin form factor and carries ECC with Load Reduced buffering in a 4Rx4 layout. Supermicro certification confirms compatibility with qualified server platforms. The LP profile fits dense chassis where vertical space is limited.

Suits servers needing maximum capacity per slot

Systems that require registered ECC memory with Load Reduced technology to populate many DIMM slots will benefit from this module. Builds limited to standard registered DIMMs without Load Reduced support cannot use this part. Environments demanding higher clock speeds than 1066 MT/s must select faster modules.

Single specification check is DDR3 1066 speed grade

The module operates at PC3-8500 (1066 MT/s) and will not run at higher DDR3 frequencies unless the platform supports them. Verify the memory controller accepts 1.35 V operation and 4Rx4 Load Reduced organisation before ordering. No other DDR generation fits the 240-pin DDR3 socket.

Questions about this item

Will this 4Rx4 load-reduced DDR3 module work in a system that currently uses standard registered DIMMs?

Load-reduced and standard registered DIMMs use different signalling; mixing them is not supported and the system will not boot with both types installed together.

How can I confirm the module is running at DDR3 1066 after installation?

Enter the BIOS or use a system information tool; the memory speed should read 1066 MT/s (PC3 8500) and the voltage should show 1.35 V.

Does the package include any heatsinks, cables or a Supermicro certification card, or is it only the bare DIMM?

Only the 32 GB 240-pin DDR3 LR DIMM is supplied; no heatsink, cable or printed certification card is included.
