32GB DDR3L 1600 server module

This Samsung memory module delivers 32GB of DDR3L capacity at 1600 MT/s with a CAS latency of CL11. It operates at 1.35V and uses a 4Rx8 organisation without a heat spreader. The part is designed for server platforms that require low-voltage DDR3L memory.

DDR3L 1600 (PC3 12800) voltage and density limits

DDR3L modules run at 1.35V rather than the standard 1.5V, so the system memory controller must support the lower voltage. The 32GB density and quad-rank layout mean the motherboard must accept 4Rx8 modules; many consumer boards only support one or two ranks per channel. Speed is fixed at 1600 MT/s and will down-clock if the platform cannot sustain that rate.

Installation notes for quad-rank server DIMMs

The module installs like any standard DIMM, but the 4Rx8 configuration places a heavier electrical load on the memory bus. Systems often require a specific slot population order or a BIOS update to recognise the full capacity. Mixing ranks or voltages within the same channel can prevent the server from posting, so verify the platform's qualified vendor list before fitting.

Questions about this item

Is this 32GB module the only capacity available for the M386B4G70DM0-YK0?

Yes, this part number is a single 32GB DDR3L 1600 module with CL11 latency and 1.35V operation.

What does the DDR3L 1600 rating deliver in an actual server?

It runs at 1600 MT/s with CL11 timing at 1.35V, providing PC3 12800 bandwidth for compatible DDR3L platforms.

How does the 4Rx8 organisation affect memory channel limits?

The 4Rx8 rank structure counts as four ranks per module; the server memory controller sets the maximum ranks per channel.
