  • SpeedDDR3 1600 (PC3 12800)
  • CAS LatencyCL11
  • Voltage1.5V
  • ECCYes

Capacity 8GB

  • ECC registered design prevents data corruption in servers
  • DDR3 1600 CL11 speed matches system specifications
  • 5 V operation meets JEDEC standard for DDR3
  • Single 8 GB 1Rx4 module fits 240-pin RDIMM slots
  • Validated for Supermicro H8 and X9DA7 motherboard series

Server ECC RDIMM upgrade

This OWC module is an 8 GB DDR3 1600 ECC Registered DIMM built for Supermicro H8DGG, H8QG6, H8QGI, H8SGL and X9DA7 motherboard series. It targets administrators extending the life of existing server or workstation platforms that require registered error-correcting memory.

240-pin registered form factor

The stick uses a standard 240-pin DDR3 interface and operates at 1.5 V with CL11 latency. Because it is registered, it cannot be mixed with unbuffered modules and will not function in standard desktop boards that lack registered memory support.

Single 8 GB 1Rx4 capacity

Each module provides one rank of 1Rx4 organisation, delivering 8 GB per slot. Systems needing higher density per DIMM or unbuffered ECC memory will not be compatible with this part.

Perguntas sobre este artigo

Does DDR3-1600 PC3-12800 CL11 cap the memory bus at 1600 MT/s on these Supermicro boards?

Yes, the module runs at DDR3 1600 with CL11 timing, so the data rate is limited to 1600 MT/s on the supported H8DGG, H8QG6, H8QGI, H8SGL and X9DA7 motherboards.

What physical slot and clearance does the 240-pin 1Rx4 RDIMM require?

It fits a standard 240-pin DDR3 DIMM socket; the module has no heat spreader, so low-profile CPU coolers or dense server chassis will not interfere.

How is the ECC registered DIMM installed, and what step is often missed?

Power down the server, open the chassis, align the notch on the 240-pin edge connector, press firmly until both retention clips click, then verify in BIOS that ECC and registered mode are enabled for the new module.
