News AMD says dual-channel DDR5-6000 is the sweet spot for Ryzen 8000G APUs

[Admin]

AMD's next-generation Ryzen 8000G APUs with integrated RDNA 3 GPU will be just fine with a dual-channel DDR5-6000 memory subsystem.

Meanwhile the max speed acknowledged on AMD's website is only 5200mhz. I cannot understand how engineers can recommend sweet spots above stated technical specifications that the manufacturer is willing to stand by. We all know the product can handle higher speeds.

Yes, same for 8700G. Full published specs (e.g., GPU 2900 MHz).

AMD's performance with 5200 is really bad compared to Intel's bandwidth scaling. I think that's why AMD has a specific recommendation on higher than technically supported whereas Intel just talks about high speed memory without specifics (most of the time, they really pushed 8000+ with 14th gen in some of their marketing). AMD did the same thing with Zen 3 and 3600 which officially only supports 3200.

I wish they'd asked about using truly high speed memory with the 2:1 U:M ratio with the APU. Hopefully when the reviews come out reviewers will be testing both configurations just to see if there's a benefit.

It's because the official supported speed complies with the Jedec standard for DDR5 which requires memory to run at 1.1V, anything else is technical out of spec from the memory controller, and thus it's up to the memory manufacture to guaranty that the memory will work at out of spec speeds and voltages.

If AMD say their CPU will work with DDR5-6000 it has to work with all DDR5-6000 ram, and that makes its AMD's problem, and they aren't going to take on someone else's product issues.

If you do a search for 32GB DDR5-6000 ram kits that run at 1.1v you will only find this kit form TeamGroup: https://www.teamgroupinc.com/en/pro...ssic-u-dimm-ddr5-black-CTCCD532G6000HC48DC01/
Which has horrible CL48 timing.

If you want a 32GB DDR5-6000 kit with low latency like CL30, you end up with this:

But it runs at 1.4V so well out of the Jedec spec.

I am not surprised DDR5-6000 is the recommended RAM. I doubt it works with anything faster, just like the desktop Ryzen 7000 series.

Not just outside of jedec but dangerous for the CPU, vsoc was the reason for the exploding cpus.
