ASRock-specific 64GB DDR4 kit

This NEMIX RAM kit delivers 64GB across two 32GB DDR4 3200 UDIMM modules built for ASRock A520M-HDV, HDVP, HDVP R2.0 and DASH motherboards. The 2Rx8 unbuffered non-ECC DIMMs run at 1.20V with CL22 latency and require no heat spreader.

288-pin plug-in modules only

The package contains the two memory sticks and nothing else; no software, no cables and no additional accessories are bundled. Installation follows the motherboard manual and typically takes minutes.

The kit matches the validated part number MD25600-328K2 for the four named A520M models. Buyers with other chipsets, DDR5 platforms or ECC requirements should look elsewhere.

Perguntas sobre este artigo

Will the 32 GB UDIMM modules need any firmware updates or cleaning over their lifetime?

No firmware updates are required for these 32 GB DDR4 modules; they operate at 1.2 V with no heat spreader, so only occasional dust removal from the 288-pin contacts is needed.

What limit appears first when the 64 GB kit runs at DDR4 3200 continuously?

The CL22 CAS latency and 2Rx8 dual-rank organisation set the timing ceiling, so sustained bandwidth is capped by the PC4-25600 specification rather than thermal throttling.

How much heat and noise do the two 32 GB sticks produce under all-day load?

Running at 1.2 V without a heat spreader keeps power draw low and the modules silent; any warmth is handled by normal case airflow over the UDIMM slots.
