Questions about this item

What real-world throughput does the PC4-21300 rating deliver once installed?

The kit runs at 2666 MT/s, giving a peak transfer rate of 21300 MB/s per module when the platform operates at its rated DDR4-2666 speed.

How does the 288-pin DDR4 DIMM interface limit speed on this board?

The 288-pin DDR4 slots on the TRX40 Creator and Taichi cap memory at 2666 MT/s, so these modules operate at their specified PC4-21300 rate without overclocking.

Will the four 16 GB sticks fit the eight DIMM slots on the TRX40 Taichi?

Yes, the kit provides four 288-pin DIMMs that occupy four of the board's eight slots, leaving four slots free for future expansion up to 256 GB total.
