AMD itself confirmed with the presentation of the Ryzen 9000 that these new processors will be able to use memory sets of max. 8,000 MT/sthanks to the implemented improvements that provide top-notch support for this type of memory without stability problems, even if we occupy four memory slots.

It may seem like something new to us, but it isn’t. Many current motherboards are getting updates to also support this type of memory with the Ryzen 7000. For example, the GIGABYTE X670E AORUS Master supports DDR5 kits at 8000 MT/s, so as I said, it’s nothing new and It’s not exclusive either. of this new generation of processors and will not be on the next motherboards with 800 series chipsets.

The fact is that with the announcement of this memory support of up to 8,000 MT/s, doubts arose again about where is the optimal level to move Ryzen 9000 nowand thankfully the answer is still very simple, at the same point we had for the Ryzen 7000, both in terms of performance and cost.

Ryzen 9000 will work optimally with RAM at 6000 MT/s and CL30 latency

With RAM kits running at this speed and having this latency, all Ryzen 9000s They will be able to develop their maximum potential without any problem. These sets are also very economical and can be found in different models with different designs and capacities.

AMD said that we can also use 6400 MT/s kits, but in this case the performance increase is so small that in most cases it is imperceptibleand yet the price for these sets is increasing considerably. On the other hand, be aware that some motherboards may have problems moving them in 1:1 mode.

If you’re wondering why it’s not worth using the kits at higher speeds, don’t worry, I won’t leave you wondering, because above 6400 MT/s UCLK Ryzen 7000 stops working and Ryzen 9000 1:1 mode with MCLK do it in 2:1 mode, which means the first will work at half the speed of the second.

UCLK is the memory controller clock and MCLK is the memory speed. If we have a 6000MT/s memory set, they will both be running at 3000MHz, which is the equivalent of the 1:1 mode I was talking about, and will offer optimal performance because they are in perfect sync. However, if we use a memory set with a speed of 8000 MT/s, the UCLK will go into 2:1 mode and will not work at 4000 MHz, but at 2000 MHz, i.e. at half the speed of RAM.

I hope this explanation helped you to solve any questions you still had about RAM speed and AMD Ryzen 7000 and Ryzen 9000 processors. If not and you have any other questions, feel free to leave them in the comments and I will help you solve it.
