Server Memory Kit

This OWC kit provides 64GB of DDR3-1333 ECC Registered memory across four 16GB modules. It is built for administrators upgrading Dell PowerEdge C2100, C6105, M910, R810 or R910 servers. The modules are not compatible with standard desktop computers or unbuffered memory configurations.

DDR3-1333 Interface Limits

The PC3-10600 standard caps transfer rates at 1333 MT/s with a CL9 latency at 1.5V. Registered buffering adds one cycle of address/command delay, which stabilises heavy loads but prevents mixing with unbuffered DIMMs. Total capacity is limited to the 64GB supplied in this four-module package.

Build and Daily Handling

Bare green PCBs without heat spreaders keep the 240-pin modules low-profile for dense server chassis. The 2Rx4 organisation demands correct slot population order per the server manual. JEDEC and RoHS compliance ensures a warranty-safe upgrade that meets OEM specifications for long-term operation.

Questions about this item

Should I pick the 4×16 GB kit or a smaller 16 GB module for my PowerEdge R810?

The 4×16 GB kit delivers 64 GB total, filling four slots at once and matching the R810's registered ECC requirement. A single 16 GB module adds capacity but leaves three slots empty, so choose the kit when you want the full 64 GB upgrade in one step.

What does the PC3-10600 1333 MHz rating mean once the modules are installed in a Dell PowerEdge R910?

The memory will run at 1333 MHz with CL9 latency at 1.5 V, providing the standard DDR3-1333 throughput the R910's memory controller expects for registered ECC DIMMs.

Does the 240-pin registered ECC interface limit the speed or capacity I can use in a PowerEdge C6105?

The 240-pin registered ECC design is the only DDR3 form factor the C6105 accepts; it caps you to DDR3-1333 speeds and 16 GB per module, which is exactly what this 4×16 GB kit provides.
