Compatible DDR4 ECC Registered Kit

This 16 GB kit contains two 8 GB DDR4 2400 registered DIMMs built for ASRock D1540D4I, Fatal1ty X99X Killer, Fatal1ty X99X Killer/3.1 and X99 Extreme11 motherboards. It targets administrators who need error-correcting memory on these specific platforms.

Two-Module Packaging and Verified Compatibility

The bundle supplies a matched pair so both channels can be populated at once. Computer Memory Solutions validates each kit against the listed boards, removing the guesswork that comes with mixing generic modules on registered platforms.

DDR4 2400 Registered Constraints

Registered DIMMs require a memory controller that supports buffering; consumer chipsets will not recognise them. The modules operate at 1.2 V and CL17, and the board will clock them down if the installed processor cannot sustain 2400 MT/s. Builders needing unbuffered memory or higher speeds must choose a different product.

Questions about this item

Will the ECC registered DIMMs need any firmware updates or periodic replacement after installation?

ECC registered DIMMs have no moving parts or firmware to update. They run at 1.2 V with CL17 timing and do not require scheduled replacement.

What limit appears first when the kit runs at DDR4 2400 continuously?

The memory controller on the ASRock X99 or D1540D4I board will reach its maximum supported frequency of DDR4 2400 before the modules hit any thermal or voltage ceiling.

How much heat and noise do the two 8 GB sticks produce during all-day operation?

With no heat spreader and a low 1.2 V operating voltage, the modules generate minimal heat and add no audible noise to the system.
