Server ECC Upgrade

This 8GB DDR3L registered DIMM is built for Supermicro A+ Server series 2022TC, 2022TG, 4022G and 4042G. It delivers ECC error correction and registered signalling for stable operation in workstations, servers, NAS systems and routers. The module runs at 1600MHz with CL11 latency and 1.35V. It will not work in standard desktop computers and cannot be mixed with unbuffered memory.

Single Module Simplicity

The upgrade consists of one 8GB stick, so you add capacity in exact 8GB increments without populating extra slots. No heat spreader is fitted, keeping the profile low for dense server chassis. OWC tests every module in-house and backs it with a limited lifetime warranty and free technical support. It replaces Supermicro part numbers MEMDR380LHL07ER16, MEMDR380LSL10ER16, MEMDR380LSL14ER16 and MEMDR380LSV04ER16.

DDR3L Platform Limits

The DDR3L interface tops out at 1600MHz and 1.35V, so bandwidth and capacity per module are capped by the memory controller of the supported Supermicro platforms. Registered signalling adds a clock cycle of latency compared with unbuffered DIMMs, which is normal for server workloads but makes this memory unsuitable for any system that requires unbuffered modules. Buyers needing higher speeds, lower voltage or unbuffered operation must choose a different platform.

Questions about this item

Will the 1Rx4 ECC registered module need any firmware updates or paired replacements later?

The module is a single 8 GB 1Rx4 registered DIMM; it operates independently and does not require firmware updates or matched-pair replacement.

What thermal limit appears first when the DIMM runs continuously at 1600 MHz in a Supermicro A+ Server?

The DDR3L 1.35 V specification is the primary constraint; sustained loads stay within JEDEC thermal limits without additional cooling.

How much power does the 1.35 V RDIMM draw and does it add audible noise in a 240-pin server slot?

At 1.35 V the module draws less power than standard 1.5 V DDR3 and has no moving parts, so it adds no audible noise.
