Dell PowerEdge 850 Compatible Kit

This 4GB kit contains two 2GB registered ECC DIMMs built for the Dell PowerEdge 850 server. Each module runs at 667 MHz with CL5 timings and a 1.8V supply. The 240-pin DDR2 design matches the system’s memory slots exactly.

Suits Maintainers of Legacy Servers

Technicians restoring or expanding a PowerEdge 850 will find the correct speed, voltage and registered ECC specification in this pair. Buyers who need unbuffered modules or a different pin count cannot use this kit.

Registered ECC with 2Rx4 Organisation

The modules are registered ECC with a 2Rx4 rank structure, a requirement for the PowerEdge 850’s memory controller. Systems that accept only unbuffered non-ECC DIMMs will not post with these installed.

Questions sur cet article

Should I buy this 2×2 GB kit or look for a 4 GB single module for my Dell PowerEdge 850?

The PowerEdge 850 requires modules to be installed in matched pairs, so the 2×2 GB kit is the correct way to add 4 GB.

What does the DDR2-667 (PC2-5300) rating mean for actual throughput in this server?

The modules run at 667 MHz with CL5 timing, delivering the standard PC2-5300 bandwidth for registered ECC DDR2 memory.

Will the registered ECC 240-pin DDR2 interface work at full speed in my PowerEdge 850?

Yes, the 240-pin registered ECC DDR2 design matches the PowerEdge 850 slots; if slower 533 MHz modules are also present the system will down-clock to 533 MHz.
