Targeted DDR4 upgrade

This 16 GB kit delivers two 8 GB UDIMM modules rated at DDR4 2933 with CL21 timings and 1.2 V operation. It is built specifically for Supermicro X12SCQ and X12SCZ-QF motherboards that require non-ECC unbuffered memory in the 288-pin form factor.

Build integration

The modules plug directly into standard DDR4 UDIMM slots and draw 1.2 V without additional power cables or cooling hardware. Using two matched sticks lets the board run in dual-channel mode, freeing remaining slots for future expansion while keeping the memory controller at its native voltage and timing.

Sustained-load behaviour

Major OEM chips from Samsung, Micron or Hynix are tested at the rated 2933 MT/s speed, CL21 latency and 1.2 V voltage to maintain stability during extended workloads. The 1Rx8 organisation ensures consistent signalling without the extra buffering overhead that server-oriented modules would introduce.

Questions about this item

Does the CL21 latency limit throughput when the kit runs at 2933 MT/s for long periods?

The kit operates at its rated CL21 timing and 2933 MT/s speed under standard JEDEC voltage, so latency stays within spec during sustained workloads.

How much heat or power does the 1.2 V, heat-spreader-less 16 GB kit produce in all-day use?

At 1.2 V the modules draw only standard DDR4 power and run without a heat spreader, keeping thermals low for continuous operation.

Which motherboard slot and population rules must my Supermicro X12SCQ or X12SCZ-QF already have free for this 288-pin UDIMM kit?

The board needs two free 288-pin UDIMM slots populated in the order the manual specifies; the kit is validated for that exact platform.
