Green bare circuit board DDR5 UDIMM memory module with black chips no heat spreader 288 pins

NEMIX RAM

NEMIX RAM 32GB DDR5 4800 CL40 1.1V 2Rx8 288-pin UDIMM memory upgrade

SKU CH-9PTR-X521R

32 GB DDR5 module running at 4800 MHz with CL40 latency and 1.1 V for ASRock Z790 Taichi boards

  • Capacity32GB
  • SpeedDDR5 4800 (PC5 38400)
  • ECCNo
  • Buffered/RegisteredUnbuffered
  • ChipsetMajor OEM Samsung, Micron, Hynix

Compatible DDR5 upgrade for ASRock Z790 Taichi

This 32 GB DDR5 module is validated for ASRock Z790 Taichi, Taichi Carrara and Taichi Lite motherboards. It targets builders who need a single high-capacity stick for those specific boards. Buyers with other chipsets or four-slot kits should verify their own qualified-vendor list.

Thermals and power at stock settings

The module runs at the standard 1.1 V with no heat spreader, relying on case airflow for cooling. Power draw stays at the JEDEC baseline for DDR5 4800, so no extra voltage headroom is required. Systems with restricted airflow may see higher temperatures under sustained load.

Build details and daily implications

A bare green PCB with 288 pins and 2Rx8 organisation fits any standard UDIMM slot. The single-rank-per-channel layout eases memory-controller training on supported boards. No ECC or registered buffering means it suits desktop workloads only. Installers should confirm the motherboard QVL before purchase.

Questions about this item

How do I install the 288-pin DDR5 UDIMM in my ASRock Z790 Taichi motherboard and what step is often missed?

Align the notch on the module with the slot key, press firmly until both retention clips click shut, then enable XMP in BIOS to run at 4800 MHz CL40.

What maintenance or replacement will this 32 GB kit need over its lifetime?

No scheduled maintenance is required; the module has no heat spreader and runs at 1.10 V, so only a BIOS update might be needed if the platform adds new memory profiles.

What limit appears first when the memory runs sustained workloads at 4800 MT/s?

The CL40 latency at 1.10 V is the primary constraint; bandwidth scales with the controller, but timing stays fixed unless the BIOS relaxes secondary timings.
