Memory for AMD Ryzen 7000: DDR5-6000 is effective and DDR5-5200 is the new standard

Shortly after the official launch of AMD Ryzen 7000 (“Raphael”), the manufacturer confirmed memory kits with DDR5-5200 as the new standard and DDR5-6000 as the effective best choice for the new AM5 -Platform. The fabric clock (“FCLK”) is now standard 1733 MHz in mode 2:1:1 to RAM and memory controller (“IMC”).

RAM specifications for Ryzen 7000 are official

AMD already had the officially highest possible supported memory standard, DDR5 with 5,200 MT/s, shortly after the introduction of the 7950X, 7900X , 7700X and 7600X on their respective Zen 4 RDNA 2 CPU product pages, revealing specifications for running DDR5 on AM5.

Fabric clock operates at 1733MHz

Robert Hallock, AMD's Director of Technical Marketing, posted more information about fabric clock and of the most effective memory speed for AMD Ryzen 7000.

• DDR5-6000 is effectively the best choice
• DDR5-5200 is the new one Standard
• The FCLK is 1.733 MHz
• FCLK-OC is not worth it

Fabric, RAM and IMC run at a ratio of 2:1:1 ex works, whereby the FCLK, which works by default at 1,733 MHz, should automatically adapt to the memory modules used.

FCLK-OC loses relevance

However, Robert Hallock emphasizes that FCLK-OC is rather negligible and, unlike Ryzen 3000 and Ryzen 5000 in particular, will no longer play a major role.

The reason why we say "AUTO:1:1" is now ideal because the FCLK will automatically change depending on what memory speed is in the DIMM slots.

There's no “one size fits all” ideal fabric frequency. For example: JEDEC 5300 fclk goes to 1767, 6000 RAM should go to 2000 fclk.

Each memory speed has its own optimal fclk, which is why I'm gently guiding people to not worry about what the fclk is because it's going to change with RAM speed and the AUTO setting will usually give the most performant result unless you have an astonishing overclocker.

And "get the highest possible fclk" is no longer the rule like it was on AM4. In short.

Up to 11 percent more gaming performance through EXPO

15 manufacturers will be offering EXPO modules at the start, with a maximum clock rate of 6,400 MT/s so far. But the mainboards don't have to be equipped with EXPO modules, although AMD likes to see that. Because XMP is still additionally supported; almost all modules are available on the market and can be operated with the Ryzen 7000. Corsair, GeIL, G.Skill and Kingston will be the first to offer corresponding EXPO storage kits.

According to the extreme overclocker Toppc, which usually competes for MSI in international RAM OC competitions, AMD EXPO and Intel XMP 3.0 are technically 100 percent compatible with each other.
