Server-Specific DDR2 Kit

This 8GB kit contains four 2GB fully buffered ECC DIMMs built for Supermicro X7DVL-3, X7DVL-E and X7DVL-I motherboards. It targets administrators upgrading legacy dual-socket servers that require registered DDR2 memory. The modules operate at 1.8V with a CL5 5-5-5 timing profile.

Capacity and Headroom

The kit delivers 8GB across four slots, leaving headroom toward the platform maximum of 16GB across six sockets. It comfortably handles typical server workloads such as virtualization hosts or database caches within that limit. Larger datasets or heavier consolidation will exhaust the available capacity before the board reaches its physical ceiling.

DDR2 667 Interface Limits

The DDR2 667 (PC2-5300) interface caps bandwidth at the rated speed, so memory-intensive tasks cannot exceed that throughput. Fully buffered signalling adds latency overhead compared with unbuffered designs. The platform requires a 64-bit operating system to address the full 16GB maximum.

Questions about this item

Will this DDR2 667 kit work with the other memory slots on my Supermicro X7DVL-3 motherboard?

The Supermicro X7DVL-3 board has 6 sockets and a maximum capacity of 16 GB. This 8 GB kit fills four of the six slots, leaving two free for future expansion.

How can I confirm the 240-pin fully buffered ECC modules are running at the correct 667 MHz speed after installation?

Enter the system BIOS or use a hardware information tool to verify the memory is detected as DDR2 667 (PC2 5300) with CL5 timings and ECC active.

The listing mentions a 4-piece kit but the package content states 2 memory RAM sticks — what exactly is included?

The kit contains four 2 GB fully buffered ECC DIMMs totalling 8 GB; the package content summary appears to be a typo.
