8GB DDR3L ECC RDIMM for Supermicro H8

This 8GB DDR3L 1600 CL11 ECC registered DIMM is built for Supermicro H8 series server and workstation boards including the H8DCT, H8DG6, H8DGT, H8DGU and H8QG7 models. It runs at 1.35V and uses a 1Rx4 organisation. The module is not compatible with standard desktop computers or unbuffered memory configurations.

Installing the 240-pin RDIMM

Installation follows the usual DIMM procedure: power down the system, open the chassis, align the notch on the 240-pin module with the slot key and press firmly until the retention clips lock. Because this is registered ECC memory, it must not be mixed with unbuffered modules and the motherboard must support registered DIMMs; otherwise the system will not post.

DDR3L 1600 registered memory limits

The DDR3L 1600 PC3L-12800 interface tops out at 1600 MT/s with a CAS latency of 11 and a low 1.35V operating voltage. Registered signalling adds a clock cycle of buffering, which improves signal integrity on heavily populated boards but prevents use in platforms that only accept unbuffered DIMMs. Capacity per module is limited to the density of the 1Rx4 devices used here.

Questions about this item

How can I confirm the 8GB DDR3L 1600 CL11 module is running at 1.35V after installation?

Enter the BIOS or use a hardware monitor; the SPD data should show PC3L-12800 at 1.35V and the system must report ECC registered operation.

What ships in the box and what else is needed to add this memory?

The box contains one 8GB 240-pin DDR3L ECC RDIMM; no cables or tools are required, but an available registered DIMM slot on a supported H8-series board is necessary.

Which capacity or version should I pick for a Supermicro H8DCT board?

This listing is the single 8GB 1Rx4 DDR3L 1600 CL11 module; match the total capacity you need by adding identical modules to the board's registered DIMM slots.
