32GB DDR4 3200 UDIMM for Hynix systems

This 32GB DDR4 3200 module uses the Hynix HMAA4GU6AJR8N-XN part number and runs at CL22 latency with 1.2V operation. It is built as a 2Rx8 unbuffered UDIMM for desktop PCs and workstations that accept standard DDR4 memory. The single-stick design suits upgrades where one slot is available.

DDR4 3200 speed ceiling and CL22 timing

DDR4 3200 (PC4-25600) sets the maximum data rate this module can deliver, and the motherboard will clock it down if the platform only supports lower speeds. CL22 latency is fixed on this stick, so tighter-timed kits already installed will force the system to run at the looser setting. No heat spreader is fitted, which keeps the profile low but offers no thermal headroom for overclocking.

Check DDR4 UDIMM slots and maximum capacity per slot

Verify the board has a free 288-pin DDR4 UDIMM slot and that the chipset or BIOS allows 32GB per slot. Confirm the system accepts non-ECC unbuffered memory, as registered or ECC modules will not work in this configuration. The module is validated against the Hynix part number, so cross-reference that exact PN with your hardware manual before ordering.

Questions about this item

Should I pick the 32GB CL22 module or look for a different capacity and latency?

This is a single 32GB DDR4 3200 UDIMM rated at CL22 and 1.20V; choose it when your board has a free 288-pin slot and you need exactly this capacity and timing.

What does the 3200 speed rating deliver once installed?

The module runs at DDR4 3200 (PC4-25600) with CL22 latency, giving a peak transfer rate of 25600 MB/s in a system that supports that data rate.

Does the 288-pin DDR4 interface limit the usable bandwidth?

The 288-pin UDIMM form factor carries the DDR4 3200 signal at 1.20V; actual throughput is capped by the memory controller in your motherboard or CPU.
