ASRock B550 ECC UDIMM upgrade

This 8 GB DDR4 module is built for ASRock Rack B550D4 motherboards that require ECC unbuffered memory. It targets administrators and builders who need error-correcting capacity for stable server or workstation operation. The single rank design fits standard 288-pin slots without registration overhead.

No accessories or software included

The package contains only the memory stick itself. No heat spreader, cables, configuration utilities or diagnostic tools are supplied. Installation relies on the motherboard firmware to detect the JEDEC profile automatically. Buyers who want RGB lighting, bundled software suites or extra mounting hardware will not find them here.

3200 MT/s CL22 at 1.20 V decides fit

The module runs at DDR4 3200 with PC4-25600 bandwidth and CAS latency 22. If the target board demands a different speed grade, lower latency or registered DIMMs, this part will not meet the requirement. Compatibility is limited to the listed ASRock Rack B550D4 models.

Questions sur cet article

Will the 1Rx8 ECC UDIMM need any periodic maintenance or replacement once installed?

ECC UDIMMs have no moving parts or serviceable components; they remain in service until a memory error occurs or the system is upgraded.

What limit appears first when the module runs continuously at DDR4 3200 CL22?

The CL22 latency at 3200 MT/s sets the throughput ceiling before thermal or voltage constraints become relevant.

How much heat and power does the 1.20 V unbuffered stick produce under all-day load?

At 1.20 V the module draws minimal power and runs cool enough that no heat spreader is required.
