The system ran two 24 GB sticks at 8600 MT/s, passing a memory test. However, UNIKO\u0026#39;s Hardware reported that voltage increases did not raise clock frequency, memory timing adjustments were difficult, and unit-to-unit variation was large. At the same clock speed, SK hynix memory delivered better performance. The findings apply to overclocking; stock operation may not be affected.\u003c/p\u003e\u003cp\u003eCXMT is being tested by Apple and MSI as a fourth memory source after Micron, Samsung, and SK hynix. MSI has already released a beta BIOS enabling DDR5-8200 on CXMT modules. Apple is seeking US government approval to use CXMT chips, which are on the Chinese military company list. The memory shortage, driven by AI demand, has made alternative suppliers attractive despite these early overclocking drawbacks.\u003c/p\u003e","blueskyPost":"Early tests of CXMT DDR5 memory show it can hit 8600 MT/s on an ASUS board, but overclocking performance lags behind SK hynix.
