We have a release date (although it’s not yet official) for the Arrow Lake-S processors. Motherboards built around the Z890 chipset will arrive at the same time. But what’s interesting today is a new leak revealing the memory supports for this chipset, and more particularly when it’s on an Asrock Z890 Taichi.
We also learn that the Z890 boards will be equipped with the latest Intel Extreme Memory Profile (XMP) 3.0x to ensure that the memories can reach the advertised clock speeds without too many problems. For its part, ASRock also seems to want to offer the Hyper BCLK engine on its Taichi motherboard. A solution that enables non-K processors to be overclocked. However, we must remain cautious on this subject, as ASRock will have to obtain INTEL’s approval for this feature. Blue team have been restricting Non-K OC for quite some time now, and the latest dramas are unlikely to relax them on the subject.
Up to 9200 MT/s for DDR5 in overclocking mode
So we discover that we could push (in O/C mode) the memory to 9200 MT/s on a strip. It now remains to be seen whether we’ll be using a “classic” chip or a chip featuring DDR5 Clocked Unbuffered Dual Inline Memory Module (CUDIMM) technology. This new technology dynamically adjusts the clock frequency and voltage according to the workload and system conditions. While this information has gone a little unnoticed in recent days, we can’t help but notice the coincidence: V-Color has announced its High Speed Overclocked CUDIMM modules in capacities of 32GB (2x 16GB) and 48GB (2x 24GB), with standard speeds starting at 6400MT/s and reaching overclocked speeds of 9200MT/s+ . We’ll also come back to the muddle between Mhz and MT/s, which will have to be clarified at some point, especially by manufacturers.
If we take the current ASRock Z790 Taichi as a reference, it supports up to 7200 MT/s+ in OC and 4800 MT/s natively on the 1DPC 1R configuration. On the Z890, we can see that native support has increased by 800 MT/s and maximum frequency support has increased by 2000 MT/s.
