System-specific DDR4 kit

This 32 GB kit contains four 8 GB DDR4 UDIMMs built for the ASUS Prime X299-A II motherboard. Each module runs at 3200 MT/s with CL22 latency at 1.20 V. The unbuffered, non-ECC design targets desktop builders who want a straightforward capacity upgrade on this platform.

Unbuffered UDIMM build

Modules use 288-pin DDR4 UDIMM form factor with 1Rx8 organisation and major OEM chips from Samsung, Micron or Hynix. No heat spreader is fitted, so clearance under large CPU coolers is maximised. Standard desktop DIMM slots accept the sticks without extra brackets or cables.

DDR4 platform limits

DDR4 tops out at the 3200 MT/s JEDEC speed this kit provides; faster operation would need manual tuning and compatible BIOS support. Total capacity is capped at 32 GB across the four slots populated by this kit. Builders needing more memory or ECC error correction must choose a different platform.

Questions about this item

What speed and latency does this DDR4 3200 CL22 kit run at?

The kit operates at DDR4 3200 with PC4-25600 rating and CAS latency CL22 at 1.20V.

Will these 288-pin UDIMMs fit the four slots on my ASUS Prime X299-A II?

Yes, the 288-pin DDR4 UDIMM form factor matches the motherboard's four DIMM slots for a 4 x 8GB configuration.

How do I install the four modules correctly on this board?

Power off, open the case, align each module notch with the slot key, press firmly until both side clips click; a common mistake is not seating both ends fully.
