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.

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.

Couldn't you have just used the integrated GPU of your Ryzen 7 7700X while your graphics card was being sent for RMA?

I believe the issue may be bad data coming over the PCIe lanes, whether it is from the memory channels or the pcie controller or maybe voltage wierdness. After a week of trying to figure out the audio/graphics card issue I am starting to get bad blocks on one of the hard drives off a pcie card, and the gb lan is throwing hardware io issues. The only thing that makes sense to me is that the PCIE channels are sending intermittent garbage.
I reposted as I have seen similar issues on multiple forums for multiple motherboards

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.

Hi,

I am using a different board but i think you had the same issues.

I am on X870 tomahawk and after upgrading to 9800x3d, started to get weird issues on boot where i could see the post msi logo freeze and windows boots up in slow motion / stutterfest.
The audio is also incredibly laggy and when i opened hwinfo, i was getting 4fps, eventually it led to a BSOD "Internal_scheduler_video_error".

Sometimes it boots up fine, mostly it's laggy. I am currently using a B650 tomahawk and all the same components and it runs fine.

However, i think the shop is sending me back the X870 Tomahawk... so i was wondering if this issue sounds like yours and if it was a case of bios downgrading to fix it?

Are you using a Logitech Unifying wireless keyboard/mouse receiver? When this happens on your system, does it show that the GPU is running at PCI-E x16 Gen 2.0 or 3.0?

The first x870 tomahawk was returned and they said was "faulty", the 2nd was returned and they have said it is NOT faulty, both had the stutter issues.

This means right now i haven't got the motherboard but very likely will be getting the 2nd back. When i do, i will check if pci-e shows as 2.0 or 3.0.

I do use a logitech g pro wireless w/ the usb receiver too. I have seen people mentioning my exact issue also, all with msi motherboards, different ones tho, including x670e - (Yet another pci5 board), he mentioned it happening on certain bios and having to downgrade to fix it, something i am expecting to have to do.

Grab a new receiver they are only $10 or so and see if it helps, I keep spares now as have had them die on me or cause stability problems several times over the years

Can't find the one i have for that cheap, however i could just test the mouse plugged in as wired without the receiver, i assume this would work fine if the wireless was the issue?

New year, new GPU (and CPU), new luck:
1739223201606.png

Wiped the contacts with isoprop before install and vacuumed the slot on low just for good measure, so far no obvious issues with PCIe 5.0 on the GPU (+SSD, now 15° C cooler bc stock pads' contact to the cooler was crap apparently) and throttles down to 1.1 correctly when there's no 3D-load running too.
Tried a few restarts, no stuck low speed either (still on only 1.245V SoC mind you).

Generally didn't explode and brick on driver install either like some reports said, cable still unmelted - only the fan stop doesn't seem to wanna be friends with the Carbon X670E.
Reviewer also had the same issue, it worked normally on a different system they tried so it's probably just some compatibility issue a BIOS/VBIOS/driver update can hopefully remedy.

Running into the same issue, tried the latest BIOS from around the 22nd of Jan, and the one before that with the issue still persisting. It's not happening all the time, however when it happens it gets stuck on PCIe 1.1. In games/heavy loads it goes up to PCIe 3.0, never 4.0. Plus when waking up from sleep it's a stuttery mess until restart.

Anecdotally, I have a theory that it can be RAM related. When I reverted to the older BIOS, my RAM reset to its standard speeds (4800MHz) which seemed to fix the issue (tested around 5 Sleep-Wake cycles). As soon as I re-enabled EXPO, it started manifesting the same issue. From what I've read around, it seems to be an issue with this MOBO/MSI specifically, so I've decided to return it and already replaced it with another manufacturer.

Just finished my new build a couple of days ago, so having to re-do it all again was a ball ache.

Specs:
CPU: 9800x3d
Mobo: x870 tomahawk
RAM: 64GB Corsair RGB Expo 6000MHz
GPU: RTX 4080
Crucial PCIe 4.0 and a couple of SATA SSDs, HDDs.

I don't have EXPO enabled. I'm running my Crucial Pro 64GB DDR5-5600 at the BIOS default of 5200 which is the official speed the memory controller on my Ryzen 7 7800X3D supports and I still had the issue. Also I don't get any memory errors in memtest86+. I'm pretty sure that nothing is wrong with my RAM.

If the issue you are referring to is the same as mine, as I've described above, it doesn't seem to be the ram stick but maybe something with the board.

When i was testing the first X870 tomahawk i had, i plugged in a complete different kit of ram and it was a 100% stutter rate (only 3 boots tho...), whereas my normal kit would boot up fine some times and sometimes not.

Happens at complete stock too, so it isn't related to overclocks or anything. It really does seem like a MSI issue though.

@dpod315cd02eb Sorry, meant to say the board has some issues with certain RAM configurations/vendors, not that the ram kits are faulty.

Yeah, it does seem to be rather MSI specific. I got a new motherboard yesterday (different manufacturer) and I've been stutter free, PCIe 4.0 works even after numerous reboots, so fingers crossed.​


For anyone else looking to get a new build, I'd steer clear of this model until we know for sure the problem has been fixed.

So far it's been about 6 days since I tried my spare Logitech unifying receiver connected to my system, and I'm not getting the lag/drop to PCI-E Gen 2.0-3.0 issue while in Windows since, or at least the issue hasn't returned completely. When say completely, I mean the last 2 power ups of my system while Windows 11 was loading there was static in the audio and in one of those power ups there was around a 2-second hesitation in the loading circle while Windows was loading. DPC latency seemed normal according to Latency Mon and PCI-E was operating at Gen 4.0 on my RTX 4090 as it should be and no noticeable input lag while navigating Windows. So I'm not sure if it's related to the same issue and not returned in a complete form.
