64GB DDR4 Kit for ASRock Workstations

This 64GB kit contains four 16GB DDR4 2400 unbuffered DIMMs built to run at 1.2V with CL17 timings. It is manufactured by Computer Memory Solutions and validated for a specific list of ASRock C236 and E3C236 series motherboards. The modules use major brand chipsets and carry a limited lifetime warranty from the maker.

Suited for C236 Workstation Upgrades

The kit targets administrators or integrators populating all four slots on supported ASRock boards to reach the platform 64GB maximum. Buyers who need ECC error correction, registered modules or speeds above 2400MHz should look at a different product. Systems that require fewer than four modules or a lower total capacity are also not the intended use case.

Drop-In DDR4 288-Pin Installation

Each stick fits a standard 288-pin DDR4 slot with no heat spreader to interfere with tight CPU coolers. The 1.2V operation matches the platform default so no manual voltage tuning is required. Filling every slot leaves no free sockets for later expansion, so plan the final capacity before installing the kit.

Questions about this item

Does my ASRock motherboard need four free DDR4 DIMM slots for this 4x16GB kit?

The kit contains four 288-pin DDR4 modules, so your board must provide four empty DDR4 DIMM sockets to install all 64GB at once.

Can I keep my existing DDR4 2400 CL17 sticks and add this 64GB kit?

Mixing modules with identical speed, latency and voltage usually works, but the board will run all sticks at the slowest common timing; for guaranteed stability use the four matched sticks alone.

How do I confirm the system sees the full 64GB after installation?

Boot the machine, open BIOS or the OS memory report, and verify the total shows 64GB running at 2400MHz with 17-17-17 timings at 1.2V.
