Server Memory Kit

This 16 GB kit contains four 4 GB registered DIMMs built to the DDR2 400 standard. It is designed for administrators upgrading a Dell Poweredge 1850 server that requires ECC registered memory. The modules run at 1.8 V with CL3 timing and use a 240 pin form factor.

Compatibility Scope

The kit suits IT teams maintaining legacy Dell Poweredge 1850 platforms that specifically call for PC2 3200 registered ECC memory. It will not work in systems that need unbuffered non ECC modules or a different DDR generation. Buyers whose servers require higher density sticks or a faster bus speed should look at other options.

Deciding Specification

The registered ECC design combined with the DDR2 400 240 pin interface is the single specification that decides fitment. Only servers that list PC2 3200 registered ECC DIMMs in their qualified vendor list will accept these modules.

Questions about this item

Does my Dell Poweredge 1850 require registered ECC DDR2 modules to accept this 16 GB kit?

Yes. The server uses registered ECC DDR2 DIMMs, and this kit provides four 4 GB modules matching that specification.

Can I keep my existing PC2-3200 sticks and add these four 4 GB modules without changing voltage?

All modules run at 1.8 V and share the same 400 MHz speed, so they can operate together if the board supports the total capacity.

How do I confirm the system recognises the full 16 GB after installing the four DIMMs?

Check the BIOS memory summary or the OS memory report; both should show 16 GB detected at DDR2 400 with ECC active.
