商品問答

How much heat and power does a 32GB PC5-6400 module draw when the system runs all day?

The module is rated for the PC5-6400 data rate; actual thermals and power depend on the host platform and workload.

Which Lenovo server models are confirmed to accept the 4X77B09751 32GB kit?

The manufacturer highlights SR635 V3 and SR655 V3 as compatible platforms for this part number.

Will a 2RX8 16Gb density stick work alongside older 1RX8 modules already in my SR635 V3?

Mixing ranks and densities is governed by the server BIOS and memory controller; consult the system memory population rules before installing.
