ASUS TRX40 ROG Zenith II Extreme compatible kit

This 32 GB dual-channel kit targets owners of the ASUS TRX40 ROG Zenith II Extreme motherboard who need a straightforward memory upgrade. Two 16 GB modules deliver the capacity in a matched pair for stable operation.

288-pin DDR4 UDIMM at 1.20 V

The modules slot into standard 288-pin DDR4 UDIMM sockets and run at 1.20 V without requiring additional cooling hardware. Unbuffered, non-ECC design keeps the signal path simple for desktop platforms that do not support registered or error-correcting memory.

Replaces slower or smaller DDR4 DIMMs

Swapping out lower-frequency sticks or single-rank modules for this 3200 MT/s CL22 1Rx8 kit raises bandwidth where the board and CPU can use it. The jump is worthwhile when the existing memory limits multitasking throughput or leaves slots unpopulated.

Questions about this item

Will the CL22 latency throttle throughput during long rendering jobs?

CL22 is the rated CAS latency at DDR4 3200; sustained workloads run at this timing without further throttling.

How hot do the bare modules get when the system runs all day?

Without a heat spreader the chips rely on case airflow; at 1.2 V typical temperatures stay within JEDEC limits for UDIMM operation.

Which motherboard slot layout is required for this 288‑pin kit to work?

The kit fits any desktop board with two DDR4 UDIMM slots; the ASUS TRX40 ROG Zenith II Extreme is a validated platform.
