Computer Memory Solutions 12GB (3 x 4GB) DDR3 1333 ECC Registered - C20

Dell PowerEdge T620 server memory

This 12 GB kit contains three 4 GB DDR3 registered ECC DIMMs validated for the Dell PowerEdge T620. The modules run at 1333 MHz with CL9 timing at 1.5 V and use a 240-pin form factor. They are intended for server workloads that require error correction and registered buffering. The kit is new and supplied as three separate sticks.

Replacing unbuffered or slower DDR3

The T620 supports both registered and unbuffered ECC memory but forbids mixing the two types within the same system. This kit upgrades from unbuffered ECC or lower-speed registered modules while keeping the memory bank uniform. It also avoids the x4 versus x8 DRAM organisation mismatch that can prevent dual-channel operation when dissimilar 4 GB modules are combined. The jump is worth it when the server needs the full 24-socket capacity with registered DIMMs.

Suits T620 owners expanding registered ECC capacity

Buyers who need registered ECC memory for a Dell PowerEdge T620 and want a matched three-stick kit will find this compatible. It is not for systems that only accept unbuffered ECC, for builds requiring a different DDR generation, or for configurations that need higher-capacity modules than 4 GB per stick.
