Single-Module 32 GB DDR4 Upgrade

This SK hynix RDIMM delivers 32 GB of DDR4 memory in a single 288-pin module rated for 3200 MT/s at CL22. It operates at the standard 1.2 V and is unbuffered, making it a straightforward capacity addition for compatible desktop systems.

Builders Needing Maximum Capacity Per Slot

The 32 GB density suits users who want to reach high total memory without populating every slot, leaving room for future expansion. Systems limited to lower-density modules, or platforms that require registered ECC memory, will not be able to use this stick.

32 GB Density Decides Fit

The decisive specification is the 32 GB capacity per module; the motherboard and CPU memory controller must support this density in an unbuffered DDR4 DIMM for the upgrade to work.

Questions about this item

Will the 288-pin RDIMM form factor fit my desktop motherboard DIMM slots?

This module uses the standard 288-pin RDIMM form factor for DDR4 desktop memory. It fits any desktop motherboard with DDR4 DIMM slots that accept registered modules; verify your board supports registered DIMMs before purchase.

What BIOS setting should I check after installing this 3200 MHz CL22 module?

Enable the XMP or DOCP profile in BIOS so the module runs at its rated 3200 MHz speed and CL22 latency; otherwise it will default to a lower JEDEC frequency.

Does this 1.20 V unbuffered module need any firmware updates or periodic maintenance?

No firmware updates or routine maintenance are required for this DDR4 RDIMM. If a memory error appears later, reseat the module or test with a single stick to isolate the fault.
