AMD’s Ryzen 7000 ‘Raphael’ Overclocking Settings Listed, Settings for 3 GHz Infinity Fabric
It has been known for some time that AMD is planning to offer some very sophisticated DDR5 overclocking capabilities in its next-generation Ryzen 7000 series ‘Raphael’ platform, but the details are still unknown. But now that the CPUs are coming out in a few weeks, motherboards and their BIOSes are starting to float around the world, revealing details of new overclocking capabilities. And they are very impressive.The latest information is here Yuri Bubryis the developer of the DRAM Calculator for Ryzen application and for obvious reasons has access to the BIOS of some of the upcoming X670E motherboards.
According to Bubliy, AMD’s next-generation platform will reportedly feature unprecedented memory overclocking capabilities. In particular, the BIOS offers two types of profiles (high bandwidth and low latency) for XMP/EXPO modules. This probably indicates whether the module is running in bonded mode (1:1) with the memory controller and fabric, but time will tell if this is the case. Also, Infinity Fabric seems to be able to dial up to 3 GHz, but it’s not clear if that’s feasible. The EXPO feature is much like XMP, so it is set to pre-allocated overclock values to simplify memory acceleration. Meanwhile, for those with more time, AMD’s upcoming platform will allow you to set the timings for each channel individually.
Indeed, AMD’s Ryzen 7000 series platform with the X670E chipset will allow owners to set asynchronous CPU and PCIe clocks, maximize CPU clocks for overclockers, and perhaps more importantly, easily overclock to make it look like the ultimate enthusiast platform. The platform also supports CCX clock control (Zen 4 has 4 cores per CCX), allowing you to set the clocks of different CCXs independently. In addition, you will be able to control the host clock.
If you want to go further, AMD’s Ryzen 7000 series systems allow you to manually set the CPU ODT and DQ drive strength impedances as well as various DRAM impedances to further maximize memory overclocking. Also, on next-generation AMD platforms, CPU CK, CA, and CS drive strengths can be manually adjusted to improve memory transfer speeds.
This is certainly an unofficial source and the information is preliminary so should be considered carefully. expected to be available.
