ASUS-compatible DDR4 3200 UDIMM

This NEMIX RAM module provides an 8 GB DDR4 3200 memory upgrade for desktop PCs. It is built as a single 288-pin unbuffered UDIMM using major-brand DRAM chips. The stick runs at 1.2 V with a CAS latency of CL22 and carries no heat spreader.

DDR4 3200 speed ceiling

The DDR4 3200 interface caps transfer rates at PC4-25600, so bandwidth cannot exceed that ceiling regardless of motherboard capability. CL22 latency is fixed on this module and cannot be tightened without stability risk. Only the listed ASUS motherboards are validated for this part.

8 GB single-rank capacity

One 1Rx8 rank delivers 8 GB total, which suits mainstream desktop workloads but leaves no headroom for memory-intensive tasks. Buyers who want more storage capacity per slot or dual-rank density should look elsewhere.

Questions about this item

Should I choose this single 8 GB module or add a second stick later?

This is an 8 GB DDR4 3200 UDIMM sold as a single stick. Adding an identical module later will enable dual-channel operation on supported ASUS motherboards.

What does the 3200 MHz rating deliver on a B660 or B760 board?

The module runs at DDR4 3200 (PC4-25600) with CL22 timings at 1.20 V, providing the rated bandwidth when the motherboard enables the XMP or default profile.

Does the 288-pin DDR4 interface limit speed on Z790 or H770 chipsets?

The 288-pin DDR4 UDIMM fits standard desktop slots; the memory controller on Z790, H770, B760 or B660 will run it at 3200 MHz without exceeding the DDR4 interface capability.
