Product identity

Kingston KVR400D2S8R3/1G is a 1GB DDR2 400 registered ECC module built for server platforms that require 240-pin DDR2 SDRAM at 1.80V. It delivers PC2 3200 bandwidth with CL3 latency and single-rank organisation.

Suitable systems and limits

This module fits servers needing registered ECC DDR2 400 memory and cannot be used in desktops or workstations that accept only unbuffered non-ECC DIMMs. Systems requiring higher capacity per slot, faster DDR2 speeds, or a different DDR generation are not supported.

Deciding specification

The registered ECC design combined with DDR2 400 speed and 240-pin form factor is the single attribute that determines whether this part will function in a given server motherboard.

Questions about this item

Does my server motherboard need a 240-pin DDR2 slot to install this 1GB module?

Yes, this is a 240-pin DDR2 SDRAM DIMM, so the board must provide a matching DDR2 socket.

Can I mix this CL3 registered ECC stick with older unbuffered DDR2 modules I already have?

No, registered ECC modules require a chipset that supports registered memory and cannot be mixed with unbuffered DIMMs.

After installation, how can I confirm the module is running at DDR2 400 with CL3 timings?

Check the BIOS memory information or a system utility such as CPU-Z; it should report PC2-3200 speed and CAS latency 3.
