Server memory kit

This 8 GB kit consists of two 4 GB DDR2 667 MHz registered ECC DIMMs built for the Dell PowerEdge R300. Each module runs at 1.8 V with CL5 5-5-5 timings and a 2Rx4 organisation. The 240-pin form factor matches the server's six memory sockets. System integrators upgrading that platform receive a matched pair tested for compatibility.

Suited for R300 upgrades

Administrators expanding a PowerEdge R300 toward its 48 GB maximum will find the registered ECC design required by that server. Builders working on desktop boards, workstations or any system that needs unbuffered memory cannot use these modules. The kit is also unsuitable for platforms limited to single-rank DIMMs or lower voltages.

Registered ECC requirement

The single specification that decides fit is the registered ECC architecture; the R300 memory controller only accepts registered modules with error correction. Unbuffered or non-ECC DIMMs will not function in this server. Confirm the platform demands registered ECC DDR2 before purchasing.

Questions about this item

Will the ECC registered DIMMs need any firmware updates or re-seating over time?

The modules are validated for the Dell PowerEdge R300 and carry a limited lifetime warranty from CMS; no firmware updates are required and re-seating is only needed if the server is moved or cleaned.

What limits throughput when the R300 runs at full load for hours?

The six DIMM slots and 48 GB maximum capacity of the PowerEdge R300 set the hard ceiling; once all slots are filled the memory controller cannot address more data.

How much heat and power do the two 4 GB sticks draw in a 24/7 server?

Each stick runs at 1.8 V DDR2 voltage and the registered buffer adds minimal overhead; total draw stays well within the R300's standard DIMM thermal envelope.
