MSI Releases New AGESA PI 1.0.0.7c BIOS Update for Higher Frequency Memory Modules and Stability Bug Fixes

Quad channel will not come to mainstream. Certainly not on existing boards and CPU's via firmware update.
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.

Especially if you consider that populating 4 slots usually results in lower achievable speed, or higher latency. Most gamers prefer speed over capacity. It's enough to have 4 DIMMs on professional boards for people who actually need the higher capacity.

in my case, not really about DDR 7000+ speeds, but more about boot times related to memory training on on MAG B50 Tomahawk with DDR5 6000 CL30 (EXPO1):

• BIOS 1.61 stable with "memory context restore" enabled (not training memory on each boot) > boot time around 20s
• BIOS 1.60 not stable with "memory context restore"
• BIOS 1.72 not stable with "memory context restore" + "high memory efficiency" enabled
• BIOS 1.74 stable with "memory context restore" + "high memory efficiency" enabled > boot time around 20s, but memory light only shows a second or so

correction:
after first cold boot today, i got the typical bluescreen ... so it seems BIOS 1.74 is NOT stable with "memory context restore" (in my system) ... turned it off again for now, but left memory "high-efficiency mode" enabled.

Technically speaking, DDR5 is quad channel, as each DIMM is 2x 32-bit...

The newer BIOS that incorporated AGESA 1.0.0.7c rectifies that issue.

hmm, yes I would also think that ... but in my case it doesn't, it seems ?
maybe it's the combo of "memory context restore" enabled + "high-efficiency mode" enabled (and on preset auto) ?

this is the one i have:

Enable both Memory Context Restore and Power Down mode for the memory. That should fix your issues.

thanks for the hint ! ... enabled both "memory context restore" and "power down mode" (and left "high-efficiency mode" enabled on preset auto)
so far , so good

now I'm curious, do you have some info as to why this helps ?

Not sure why it's necessary, just know it's the solution to getting memory context restore to work.

yes, seems to work fine so far, thx for sharing ! ... and if you have more of these recommendations, please let us know

Semi-related note, MSI also issued BIOS updates for their Intel motherboards with support for 14th Gen and even more work on memory training.

Please for the love of God no! Leave the 4 Dimms alone. At least that way when Quad channel memory comes into the mainstream we will already have the space set aside for it without losing MORE features.

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.

What are you actually trying to achieve? The Asus X670e Pro Art has 4 M.2 slots, 10Gbe and USB4/TB4. You're either moving data around, or processing it in some way. 10Gbe is 1250MBps and 40Gb would be 5000MBps. Which is the max you can get data in or out of the computer, and both are lower than a single Gen4 NVME SSD. Never mind having the option of 2xGen5. That's also ignoring the fact that few operations are sequential to even get the max potential throughput, and NAND write holes. Most common disk access patterns are similar to or marginally better than SATA SSDs. Almost nothing nearly anyone would ever hope to do on the consumer platform needs or can even use all that bandwidth.

The 7950X can do decompression in something like 7-zip at a max of 2900MBps, and next to no other common CPU heavy task approaches even that. GPUs don't even really need the full x16 lanes for gaming or GPGPU tasks. Mining rigs run GPUs at 1x for example. Running the 2 x16 slots at x8 is going to be fine a majority of the time. Sure using the 3rd PCie slot on this board splits m.2#4 to x2, but that is still 4000MBps that can barely be put to full use anyway. You aren't really at risk of being IO limited for anything you're likely to ever do on the platform. Since you can put 4 on the board, a quad NVME card is effectively just a neat bucket of NAND, because there aren't a lot of ways to use the potential combined bandwidth. You'd end up needing a platform and CPU with more memory channels and cores before that. Gen 5 levels of bandwidth only might be meaningful by the time AM5 is EOL. Could stripe 2 Gen 5 NVME if you actually "needed" the bandwidth of a quad gen 4 card.

I can run a NAS in a VM with 4 threads and 8GB mem allocation and get 800MBps with 4 7200RPM HDDs, which is close enough to the peak of the 10Gbe interface without even using a NVME cache drive. On the onboard sata. I could double that with 8 HDDs and a HBA card in the 3rd slot. In theory a 4x sata SSD array would likely be north of 1500MBps. SSDs won't likely ever be cost effective for NAS use compared to HDDs though. If you just want several big buckets of NAND, might as well embrace the SATA ports.
