MSI Releases New AGESA PI 1.0.0.7c BIOS Update for Higher Frequency Memory Modules and Stability Bug Fixes
MSI, today, released a new AMD AGESA PI 1.0.0.7c BIOS update for all MSI's motherboard X670E, X670, B650, A620 product line. For this new BIOS release, MSI focus on and prioritize mainly for higher DDR5 memory module support and also stability bug fixes. The latest update has huge significant increase for supported memory frequency on AMD Ryzen CPUs. Below is a list of models that will be ready at the time of the release while other models will have come support in the following week.
In the screenshots below, demonstrates running a Memory Stress Test, on an AMD Ryzen R7 7700X CPU with a paired of dual-channel DDR5-7200 MHz "EXPO" certified kit on MSI's PRO B650-P WIFI Motherboard will run without any stability issues. Moreover, it also demonstrates running a Memory Stress Test on an AMD Ryzen R9 7900X CPU with MSI's MEG X670E ACE Motherboard can even achieve 8000 MHz (CL36) high frequency. A few more updates specifically on the AGESA 1.0.0.7c added extra for protection for reliability than before and also patched a few potential vulnerabilities and security loopholes.

That being said there is mostly also no performance uplift.
I am looking at doing a BIOS update and seeing where it can go.
4x Single rank is doable. My personal HWBot record is using 4x 6200, but I wouldn't run that daily due to the voltage required to get it stable. UCLK:MCLK/2 (Gear 2) could be instead, but that defeats the purpose of the higher performance.
I do need to invest a lot more time in tweaking and getting the absoloute best as I have pretty much just thrown settings at it and seen if it sticks.
With PCIe 5.0 and DDR5, those design rules have gotten even tighter, so you don't want to go shoving some noisy 12 V power right next to those parts.
There's a reason why motherboards are designed the way they are, it's not as if these companies put components where they are at random.
Some placements have very strict tolerances and if you screw that up by 0.5 mm, the boards won't work.
For example, that front mounted M.2 slot requires a redriver/retimer to work, those add cost, but I guess you don't mind paying $5 extra in the end for each moved M.2 slot?
e.g.

In case of the M.2 slots, doable, but it will most likely, as I said, require redrivers/retimers and that adds cost to the end user. That said, many motherboards have them even on standard ATX boards, due to it being the only way to get around the component placement limitations the form factor has.
Routing PCIe lanes from the CPU past/under the DDR5 DIMMs isn't the best of ideas I'd say and I presume Dell hooks up the M.2 slots to the chipset.
The best "picture" of the motherboard in that thing appears to be this render, so it's not possible to tell what components are used and the redrivers/retimers could be on the flip side of the motherboard anyhow.
I agree that the desktop PC needs an overhaul from the ground up, as the ATX form factor isn't really fit for purpose today.
However, just moving things around, especially when you don't appear to undestand much about PCB layout and design, could cause issues elsewhere.
We're already at 8 to 10 layer boards on the high-end and with PCIe 5.0, there's no way to go back to fewer layers, largely due to noise/interference.
PCB traces are also getting shorter and shorter because of it, which means we have more limited options in terms of where PCIe 5.0 expansion slots and M.2 connectors can be fitted on the boards. Unless someone comes up with a solution that allows for high-speed interfaces to work over longer PCB traces without increasing cost, I don't see any motherboard maker moving bits around just for the heck of it, at least not until we have a new motherboard form factor.
The fact that PCI-e lanes are SO limited on the mainstream is pretty infuriating actually with the ability to do things like PCI-e bifurication for quad nvme drives on a single x16 slot also 10/40Gpbs being relatively easy to get into networking wise as well.
Im just looking back to the days of things like the X58 UD9 and imaging the mad setups people could do with that amount of PCI-E lanes even if they were all only Gen 4 at the moment.
Also you misunderstand me. Im not saying that 4 DIMM boards should not exist.
Im saying they should be properly geared towards their intended usecase. Meaning 192GB support. 10G LAN etc.
Currently these slots are wasted. Even people buying standard 2x16GB kits. How many of them really need to add another 2x16GB in the future for games?
I say very few. Most will never populate these empty slots.
