Nope, only exact same as the last beta:
- AGESA ComboPI 1.0.0.7a updated with the required solution.

So far after punching in all my settings again, I've noticed the following two new entries in the BIOS:
Under OC there is a setting below Memory Context Restore called Memory Failure Retry Count which defaults to 1, nice to have for memory settings which only sometimes fail to train I guess.

Under ACPI Settings there is a new entry called CPU Fan Fail Warning Control which defaults to Disabled, which is also a good addition.
Not sure why it's set to disabled as default though, shouldn't the opposite the case and only need disabled if you're not running a fan/pump but some other external solution like LN2 or a chiller maybe?


The time spent on post code 15 (memory training) was also cut down massively on my settings (MCR auto, PD off) to around 32 seconds - Last BIOS time reported by task manager was way over 100 seconds easily on the prior beta BIOS, now it's consistently below 50 seconds. I wonder if I force MCR to enabled if it would affect anything and be even faster (or if I'd get BSODs like some reported with PD off), gonna try later.

Unfortunately the PCIe 1.1-bug still is present and showed up quite fast on the third and fourth reboot in a row, while on the fifth everything was fine again:

Once it runs at 4.0 I don't notice any instability, crashes or the like - so I'm not sure why that happens, if the signaling was bad wouldn't it have issues at 4.0?

I've got a Crucial T700 5.0 4TB on the way, maybe even this week already which will replace the slow WD Blue SN550 3.0 250GB (which will go into an external case) in the slot closest to the CPU - wonder if changing that will impact this pesky PCIe 1.1-issue, if at all.


Oh yeah, almost forgot:
Trying to get into M-Flash to update the screen froze and I was greeted with a 00 on the post code.
I pressed the power button on the case first to try getting a shutdown but that just restarted the system and then it went into M-Flash - after which I flashed the new BIOS without a hitch (should've probably rebooted cleanly and try again but yeah...).
Odd behavior to say the least.

They did have that problem previously

Also, please everyone

Hi Guys just a update

MSI have replicated the long boot times after enabling A-XMP/EXPO
Up to 3 minutes With DDR5 5600MHz A-Xmp ram on B650 and X670(E) Motherboards
Msi is actively testing other configs and working on a fix.
I will update you when I receive the news it has been rectified.

Thank you for all your input it helps a lot.
Hi Alan,

Long time we don´t talk :) ! This fix would be delivered as a new BIOS in MSI Center? The new BIOS solve the VSoC voltage issue (<1.3v)

Greetings and thanks!

Soo...updated to the latest stable BIOS version 7D70v1J and tried to provoke the error by loading EXPO (and therefore getting 1.3V SoC), so far 15 cold boots in (as in system=off) and no 1.1 or 3.0 in sight.
Any other users with this issue seeing an improvement after updating the BIOS or was it maybe just a fluke on my side?
Be that as it may, still going to keep SoC at 1.22V or 1.23V for now just to make sure. 🙏

Checked the PCIe5-SSD (Crucial T700 4GB) ~7 times or so in CrystalDiskMark too if it ran at full x4-speed after booting and noticed no abnormalities there either.

Edit: Bit OT but does the latest BIOS just ignore higher tREFI-values? Entered the max. of 65535 but it keeps sticking to 50000.

Edit2: Cleared CMOS again and entered RAM timings manually without touching EXPO this time and now tREFI values are recognized and change accordingly. Which is a bit strange bc I cleared CMOS the first time and imported the timings from an USB-profile but I guess loading EXPO once before entering the timings and then saving the profile made tREFI stick to 50K forever🤔.

I think I am going to sit back and see other people try the BIOS with AGESA 1.2.0.0A and see if it fixes all the issues regarding the Graphics cards PCI-e 1.1 issue and the NVME issues and also a better booting time. Fingers crossed !
 
Hello, I recently build a gig with following parts:
MOBO: MSI MAG x670E Wifi
GPU: MSI RTX 4080 Super Ventus
CPU: AMD Ryzen 7800X3D
RAM: CORSAIR VENGEANCE® 32GB (2x16GB) DDR5 DRAM 6400MT/s CL32

I have weird behaviour, sometimes not always I would start the computer from cool boot or even simple restart and my GPU would be stuck on PCIe x16 1.1, causing my system to go crazy slow, can not even open any program smoothly, everything is lagging, if I open for example FurMark it will show FPS below 14, if I restart the system then everything is fine with PCIe x16 4, but sometimes it gets only to PCIe x16 3 and is very random, when system is ok I can play games without issues.

I have been following this thread trying to find answers, I think I tried everything, different BIOS, different PCIe configuration forcing Gen 4, etc, I would appreciate any recommendation, right now I have set vsoc 1.20, XMP is turn off.
I'm on latest BIOS version for my MOBO 7E12v1E with AGESA ComboPI 1.2.0.0a Patch A updated.
I do not know if the motherboard does not like the GPU or if the GPU is faulty or if motherboard if faulty.

Hi there, i use a bios from april 2024, worx most stable for me. Running through different issues with the board, mostly to bios problems.
7D70v1G1 is the version i am using.

Nope and I'm now running a Retail CPU the R7 7700X was way to cheap to pass up and I did not see much point in upgrading to an R7-9700X

Ok, after working on this problem i think i have found the issue....
The problem disappeared after using another PSU, and after using its own PSU the problem occurred again. The current PSU is a Thermaltake 1600W, the PSU for test was 800W.
For me this resolve worked, hope for most of you to work also.

Coincidentally I was checking out PSUs which can do high loads passively yesterday, with the NZXT C1500 Platinum looking as a good option (esp. for the price asked compared to other vendors).
Since I'm using a 750W be quiet!-PSU (which isn't far off of your 800W-PSU that had the problem, if I interpret that right), it might just be the right solution.

Unfortunately the problem came back after 1 day of testing, so i decided to test with another Motherboard, and the problem dissappeared. Then i put another CPU on the "problem" motherboard and the problem appeared on the minute. So finally the problem is resolved with new motherboard, different brand, the problem one was MSI, so I decided not to risk it and used different brand.
 
Hi everyone, older thread, but i ran into the same issue and been trying to fix it for a month to no avail. Has anyone managed to fix this problem for good?

MOBO: MSI x670e gaming plus wifi (using latest BIOS update 7E16v19, have tried different versions but no change unfortunately)
GPU: gigabyte 4080 super gaming oc
CPU: Ryzen 7 7800x3d
RAM: 2x16GB Patriot Viper 6000 series
SSD: Lexar 2TB M.2 4.0
 
I purchased an MSI X670E Tomahawk WiFi motherboard with a Ryzen 7 7800X3D around April '24. I upgraded from a Ryzen 7 5800X3D with a Asus B550 Strix WiFi motherboard and already had a Founder's Edition RTX 4090 graphics card which I transferred to the new build. I'm also having a similar issue except I never witnessed it drop down to PCI-E x16 Gen 1.1. It would either drop down to PCI-E X16 Gen 2.0 or 3.0 and I verified this with the NVidia Control Panel's system information section and GPU-Z. The issue started happening on my system around early November '24, a few days after a BIOS update of my motherboard, and didn't happen again until 2 weeks ago and happens now way more frequently, like once every 1 or 2 days. When it happens the mouse cursor lags greatly and I get noticeable input lag when typing on the keyboard, folders take noticeably longer to open, apps load longer, CrystalDiskMark scores lower, CPU benchmarks score lower, and lots of static in the audio, and the spinning circle seems to hesitate during the last few seconds while loading Windows 11. Also DPC latency is several magnitudes higher when the issue occurs as I verified with LatencyMon. In fact, I know if the issue is happening without even checking the speed of the PCI-E mode and someone here several months back in this thread mentioned the same thing that this person could tell when the issue occurs without check what the PCI-E speed was operating at. So I think I have the same issue here. However, this issue only happened when I had the wireless receiver connected to my PC and it happens on all the USB ports I tried so far, I tried the USB Port in the front of the case and one of the rear USB ports and tried a USB switchbox and the issue still happened, however, if connected through the USB switchbox or one of the front USB ports on my system, it will drop to Gen 3.0 instead of 2.0, and not lag as much but still noticeable and still static in the audio. If the wireless receiver is connected to a rear USB port, it will drop to PCI-E x16 Gen 2.0 on occasion with even more input lag and more sluggish feel to the system. Also a reboot of the system fixes this issue temporarily and the issue returns in a day or two. I'm currently using the latest BIOS and the latest drivers specific for my motherboard and graphics card, and did a clean install of Windows 11 a few days ago. When I don't have my wireless receiver connected to the system and I connect my wired keyboard and mouse, the issue doesn't show up, or at least not yet. Weird thing is, the first 7 months I had the system, and mostly using the wireless keyboard and mouse, the issue hasn't showed up. This issue didn't happen on my previous system with the same graphics card and wireless keyboard and mouse. Anyone here using a wired keyboard and mouse and still getting the issue? Is this a BIOS issue that can be fixed with a future BIOS update, a chipset driver issue, a motherboard issue, or a CPU issue? Has this issue happened on Intel systems as well?

I was getting it some time ago on a full AMD rig even sent the GPU in for RMA and it passed.
I found it was the Logitec Wireless receiver. I replaced the Reciver and it has not played up Since
So I would have to say the Receiver while working perfectly with attached devices was faulty

I have a spare Logitech wireless receiver that I can test out. I would think that a defective wireless receiver would just cause signal dropouts or not work at all and not affect the actual system.

Thinking that cost me almost 1K as I purchased a New GPU to replace the one I sent to RMA
And the receiver was working perfectly with connected devices so a $12 receiver cost me $1000 as I assumed it was working without a problem.
