Toppc, a professional overclocker, competes under the MSI flag. He uses an unknown development model processor from AMD Ryzen 7000 series (“Raphael”), with 64 gigabytes DDR5-6400 memory and a sharp CAS latency (32 clock cycles). CL32-38,38,96-134 are the memory timings.

There is a boom in emerging screenshots, benchmarks and database items for pre-series processors. These are the Engineering Samples or Qualification Samples (QS). The next-generation Intel desktop hybrids (also known as Raptor Lake) consist of an i5-13600K, an i7-13700K and an i9-13900K. In various benchmarks and databases, an i9-13900K with DDR5-6600 is the most recent AMD Ryzen 7000. Toppc, an overclocker on Chinese video sharing platform bilibili, has posted the current memory settings of a future preproduction model. It is based on Zen 4.

The image was published by a Chinese overclocker under the title “Toppc AMD CPU”, and CPU-Z screenshots the RAM as DDR5, so it cannot be a Zen 4 desktop processor.
Both platforms will be available “out of the boxes” for the CPU duel between Core i 13000 series vs Ryzen 7000. Support for DDR5-5600 is also provided. Anyone using Intel XMP 3.0 and AMD RAMP or EXPO should be able to easily overclock the DDR5 DIMMs.
DDR5 has much to improve upon
If you have the right memory kit with fast ICs, it would be possible to overclock RAM at an extremely high level. JEDEC has officially designated memory speeds from DDR5-3200 to DDR5-8400, and other clock speeds are also available.
SK Hynix had promised DDR5 RAM at an effective 8,400 MHz over two years ago. Adata, however, promised DDR5 RAM at up to 12,600 MT/s at voltages of up to 1.6 volts when Adata’s new memory generation was launched. Such fast memory is unlikely to become available before 2023. Raptor Lake and Raphael are expected to play a duel from DDR5-5600 to DDR5-7200
