Overview
- MSI published region‑bound beta AM5 BIOSes that its China channel says validate CXMT modules on select motherboards, unlocking dual‑DIMM support up to DDR5‑8200 and raising quad‑DIMM ceilings to DDR5‑7200 with MemTest stability reported.
- MSI’s reported tests used specific rigs and modules — 2x24 GB 24Gbit sticks on an MEG X870E Unify with a Ryzen 7 9700X reached 8,200 MT/s and 2x16 GB 16Gbit sticks on a MAG B850 MPower with a Ryzen 5 9600X hit 8,000 MT/s — which suggests results may rely on carefully chosen silicon and setups.
- Lexar has moved to commercialize CXMT chips in retail 'THOR II' DDR5 kits, listing 32 GB (2x16 GB) dual‑channel products rated at DDR5‑7600 CL38 and DDR5‑7200 CL38 per vendor listings and CPU‑Z evidence.
- Together these steps show CXMT DRAM moving past its prior ~6000 MT/s practical limit and give PC builders lower‑cost routes to high frequencies, but the current gains are shown in region‑restricted BIOS builds and limited test configurations.
- Broader impact will hinge on global BIOS rollouts, wide motherboard and CPU validation across chip batches, and independent testing to confirm performance and reliability for everyday users.
