Dell PowerEdge R805 DDR2 kit

This 8 GB kit contains four 2 GB DDR2-667 registered ECC DIMMs built for the Dell PowerEdge R805 server. Each module runs at 1.8 V with CL5 5-5-5 timing and uses a 240-pin 2Rx4 layout. The registered buffer helps the platform address its full 16-slot capacity.

Server-only ECC registered upgrade

The modules suit administrators who need to populate or expand a PowerEdge R805 with validated ECC registered memory. They will not work in desktop boards, laptops or any system that requires unbuffered non-ECC DDR2. Buyers needing higher density per slot or a different DDR generation must look elsewhere.

16-slot registered DIMM limit

The R805 accepts up to 16 registered DIMMs across two banks of eight, so this four-stick kit fits directly into that architecture. Exceeding the slot count or mixing unbuffered modules will prevent the server from posting.

Questions about this item

Should I choose the 8GB kit with four 2GB modules or a different capacity for my Dell PowerEdge R805?

The kit provides 8GB total across four 2GB registered DIMMs, matching the server's 16-slot layout in two banks of eight.

What does the PC2-5300 667MHz rating mean once the memory is installed in the R805?

It runs at 667MHz with CL5 5-5-5 timing at 1.8V, delivering the rated DDR2-5300 bandwidth for the server's memory controller.

Will the 240-pin DDR2 registered ECC interface work with the PowerEdge R805's memory controller?

Yes, the 240-pin DDR2 registered ECC DIMMs are the specified module type for the R805's 16 sockets.
