Compatible ASUS TRX40 Upgrade

This 64GB kit contains four 16GB DDR4 UDIMM modules tested for the ASUS TRX40 ROG Zenith II Extreme motherboard. It targets desktop builders who want a matched set that installs without manual timing changes. Systems needing ECC or registered DIMMs should look elsewhere.

3200 MT/s CL22 1.2 V Specification

Each module runs at DDR4 3200 (PC4-25600) with a CAS latency of 22 at 1.20 V. The 1Rx8 organization and 288-pin unbuffered design match the motherboard's validated memory list, so the kit posts at rated speed without voltage increases.

Four-Module Kit Only

The package supplies exactly four 16GB sticks and no heat spreaders, cables or software. Builders who need a different capacity or prefer modules with thermal armour must choose another kit.

Questions about this item

What does 3200 MT/s mean once the kit is installed in a desktop?

The modules run at 3200 MT/s when the motherboard enables the matching DDR4 profile, giving 25600 MB/s peak bandwidth per stick.

How does the 288-pin DDR4 interface limit this memory?

The 288-pin UDIMM slot caps speed to the DDR4 standard and only accepts unbuffered non-ECC modules like these.

Will the four 16 GB sticks fit a standard ATX board without a heat spreader?

Yes, each 288-pin UDIMM is low-profile with no spreader, so all four sit side by side in regular DIMM slots.
