Four green DDR4 UDIMM sticks without heat spreaders

NEMIX RAM

NEMIX RAM 64GB (4x16GB) DDR4 3200 CL22 ECC UDIMM memory upgrade

SKU CH-8Z64-KQG27

A 64 GB kit of four 16 GB DDR4 3200 CL22 ECC unbuffered UDIMMs at 1.2 V for Supermicro systems

  • ECCYes
  • Buffered/RegisteredUnbuffered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.20V
  • 64 GB total capacity from four 16 GB modules
  • DDR4 3200 speed with PC4-25600 bandwidth rating
  • ECC unbuffered design protects data integrity in servers
  • 2 V operation matches standard DDR4 voltage
  • 288-pin UDIMM form factor fits SuperMicro R12SPD-A

Target system

This 64GB kit is built for Supermicro servers and workstations that require DDR4 3200 ECC unbuffered UDIMM memory. It suits administrators who need to populate four slots with matched modules for maximum stability.

ECC and rank structure

Error-correcting code protects data integrity during sustained workloads while the 2Rx8 organisation allows each 16GB module to address two ranks. The CL22 timing and 1.2V operation match the platform specification without additional tuning.

Slot population

Four 288-pin UDIMMs install in minutes by aligning the key notch and pressing until the retention clips latch. Systems that require registered DIMMs or a different voltage will not accept these modules.

Questions about this item

Will the 2Rx8 Samsung Micron Hynix chips on these modules need any firmware updates or reseating over time?

The modules use major OEM chips and are stress tested under load; no firmware updates are required and reseating is only needed if the system is moved.

What is the first limit reached when the 64 GB kit runs at 3200 MT/s CL22 continuously?

The CL22 latency at DDR4 3200 sets the throughput ceiling before voltage or thermal limits appear.

How much heat does the 1.2 V unbuffered UDIMM kit produce during all day operation?

Running at 1.2 V without heat spreaders keeps thermals low; the ECC unbuffered design adds minimal power draw under sustained load.
