16GB DDR4 3200 UDIMM for ASRock A520M

This 16GB DDR4 3200 module is built for ASRock A520M series motherboards including HDV, HDVP, HDVP R2.0 and HDVP/DASH. It runs at PC4-25600 speed with CL22 latency and 1.2V operation. The single-rank 2Rx8 unbuffered design fits standard 288-pin desktop slots.

Suitable for single-slot upgrades on listed ASRock

Builders expanding memory on a compatible ASRock A520M board can install this stick directly. Systems requiring ECC error correction, registered modules, or a heat spreader should select a different part. The module is also unsuitable for laptops or servers needing specialised form factors.

288-pin DDR4 UDIMM interface determines fit

The 288-pin DDR4 UDIMM form factor is the sole physical specification that decides compatibility with the motherboard slot. Verify the board accepts non-ECC unbuffered DDR4 at 3200 MT/s before purchase.

Questions about this item

Will the 1.2 V DDR4 modules need any periodic cleaning or replacement?

No scheduled maintenance is required; the UDIMM has no moving parts or heat spreader, so it simply stays seated in the 288-pin slot for the life of the system.

What limit appears first when the 3200 MT/s kit runs sustained workloads?

The CL22 CAS latency and fixed 1.2 V voltage set the performance ceiling; the modules do not support XMP or higher speeds, so bandwidth tops out at the rated PC4-25600 level.

How much heat and power does a single 16 GB stick draw during all-day use?

At the standard 1.2 V DDR4 voltage the module draws only a few watts and runs cool without a heat spreader, producing negligible noise inside the chassis.
