New Agesa released 1.0.0.7B, massive memory speed boost for Ryzen 7000 on AM5, up to 8200MT/s now stable on Ryzen!

I guess I'd be interested to know how high the DRAM frequency can be pushed with stability at 1:1 (RAM:IMC).

Anyone tried that yet?

I couldn't get stable over 6000mhz before bios update, now 6400mhz with some tuning, no problem. Won't go higher as gains not worth the extra voltage and stability issues.

Do let me know if there's any success with that. :)

I may or may not grab new RAM if that's a viable approach. But for me, 96GB isn't enough RAM for what I do so will need to wait on larger capacities anyway. And by that point, just might stay on 3600MHz, but jump to 256GB RAM. As I don't think I gain much in terms of more RAM speed anyway vs the capacity for most of the stuff I do, just minor improvements that I can live without. It's basically the VRAM issue in GPU's, if you have the VRAM, you can run it (slower), but if you don't have the VRAM, you can't run it full stop.

Higher capacity modules are unlikely for desktop as dropping nodes does not bring much for RAM which is why we have 24Gb chips and not 32Gb ones. If you need so much RAM, Intel W790 or Threadripper is the best option, I would go with the W790 platform over Threadripper. The W790 platform has 8 RAM slots and is quad channel registered DDR5 so you could easily run 256GB+ at 6000+.

I think 6400mhz to 6600mhz is the new sweet spot, anything higher and you'll have to drop to 1:2, 6600mhz 1:1 is only possible though if your fclk will do 2200, you need a golden chip for that though, mine wont do anymore than 6200mhz CL30 though, its M Die based, but its 2 x 32gb Sticks, so double sided, same as running 4 single sided sticks, im quite happy with the speeds though, im using buildzoids timings which are pretty tight with a 200mhz overclock, got the same with the previous bios as I am with the beta.

That's pretty good if amd can make the memory controller stable at 7200. Intel is rumoured to be offering 8000mt/s JEDEC on upcoming architecture so not quite on par but 7200 is still very nice

It's different because Intel tends not to support a 1:1 ratio between the DRAM and the memory controller.

Whats the recommended bios for the msi boards? Ive just got a tomahawk x670e and the only bios on their site are old:

TitleAMI BIOS
Version7E12v141(Beta version)
Release Date2023-07-03
File Size9.28 MB

Description:
- Improve system stability when the EXPO function is enabled.- Fix BT device on/off issue.


TitleAMI BIOS
Version7E12v13
Release Date2023-05-26
File Size9.28 MB
Description:
- AGESA ComboPI 1.0.0.7a updated with the required solution.

Im thinking the non beta version would be best as its a brand new untested board and hope the new bios is out soon.
