System-Specific DDR4 Kit

This NEMIX RAM kit delivers 16GB of DDR4 memory in a matched pair of 8GB modules built for ASRock A520 motherboards. It targets desktop owners who want a straightforward capacity increase on these specific boards. The modules are validated for the listed models to avoid trial-and-error compatibility issues.

DDR4 3200 Interface Limits

The memory runs at the standard DDR4 3200 speed with a CL22 latency at 1.20V on the 288-pin UDIMM interface. This JEDEC-rated combination sets the practical ceiling for bandwidth and timing on the platform. The unbuffered non-ECC design means the kit cannot be used in systems that require registered or error-correcting modules.

Upgrade From Lower Capacity or Speed

The kit replaces a smaller DDR4 kit or slower modules to give the system more headroom for multitasking and memory-heavy applications. The jump is worthwhile when the board has free slots or when existing sticks are below 3200 MT/s. It is not for buyers who need ECC protection, registered DIMMs or capacities beyond 16GB in this form factor.

Questions about this item

Should I choose the 16GB kit or a single 8GB module?

The 16GB kit provides two matched 8GB modules for dual-channel operation, while a single module would run in single-channel mode and halve memory bandwidth.

What does the 3200MHz rating mean for actual system performance?

The modules run at DDR4 3200 (PC4-25600) with CL22 latency at 1.20V, delivering the rated throughput when the motherboard enables the correct profile.

Is this DDR4 UDIMM compatible with standard 288-pin desktop slots?

Yes, it uses the 288-pin DDR4 UDIMM form factor, fitting any desktop board that supports DDR4 3200 non-ECC unbuffered memory.
