Performance System Memory: Memory Read Test
So, for memory we had some proper DDR4 DIMMs to work with. These allow for your usual JEDEC frequency but also XMP/BEMP profiles at 3,866 MHz, in the BIOS once you enable the profile, all of a sudden these run at 3,866 MHz / CL18. Combined with a dual-channel configuration.
Above, the memory at default 2,133 MHz (CL15), at roughly 31~32K
So, for memory we had some proper DDR4 DIMMs to work with, Intel has a couple of certified partners for memory to get some sweet XMP 2.0 profiles going. We use a GSKILL 3866 MHz 16 GB Trident-Z kit. unfortunately when selecting the XMP profile, the system refused to boot. SMC is not (yet) compatible with 3866 MHz memory.
