Axiom 16GB DDR4-3200 UDIMM

This 16GB DDR4-3200 UDIMM provides a straightforward memory upgrade for desktop systems that require standard unbuffered modules. It operates at 3200 MT/s with CL22 latency and 1.20V voltage, matching common OEM specifications for reliable integration.

Intel XMP 2.0 profile support

The module includes an Intel XMP 2.0 profile that allows the system BIOS to configure the rated 3200 speed and CL22 timings automatically. Without this profile the memory would typically run at a lower default speed, so the profile restores the advertised performance level.

Unbuffered non-ECC desktop DIMM

The unbuffered, non-ECC design is intended for consumer desktop motherboards and is not compatible with servers or workstations that require registered or ECC memory. Builders needing error correction or registered modules must select a different product type.

Questions about this item

Will the unbuffered DDR4-3200 module need any firmware updates or re-seating over time?

No firmware exists on this UDIMM; it is a passive component. Re-seating is only needed if the system is moved or the slot oxidises, which is rare in a desktop that stays in place.

What limits sustained throughput on this CL22 1.20 V kit?

The CAS latency of 22 cycles at 3200 MT/s sets the access granularity, so sustained bandwidth tops out at the rated PC4-25600 ceiling rather than any thermal throttle.

How much heat and noise does the 16 GB stick add when the PC runs all day?

The module draws 1.20 V with no active cooling, so it adds negligible heat and zero noise; system fans dominate both thermals and acoustics.
