Re: R710 Memory Upgrade possibility with 16GB module

Dont we have 16GB 1066mhz supported module for R710?

Yes, but I don't see a price difference between the speeds. The 1066 DIMM is a quad rank DIMM. I don't see a reason why anyone would purchase it. Quad rank DIMMs are limited to a maximum of 2 per channel, and quad ranks are limited to a maximum of 1066MHz. Here are all of the DIMMs I show currently available for the R710:

A5008568 229.99  16GB 1333MHz Dual Ranked Low Volt RDIMM
A5184178 229.99  16GB 1333MHz Dual Ranked Low Volt RDIMM
A5095849 229.99  16GB 1066MHz Quad Ranked Low Volt RDIMM

Thanks

Quad rank DIMMs will operate at a maximum of 1066 MHz when populated 1 per channel. When in max population of 2 per channel they will operate at 800 MHz. They will operate at a maximum of 800 MHz on the 1.35v CPU even with minimum population of 1 per channel.
