but on a serious note, might be voltage sensing.. (due to BIOS?) or due to contacts.. (less likely since we assume they worked before the update). wild suggestion to rule out L1.
Layer 1 tshoot, clean all the contacts on the series of serial connections between the problem black magic fans?
 
Hello all,
I also had the "PCI-express low version lock" when booting which meant heavy stuttering in Windows (and unexpected resets if I waited long enough) unless I rebooted.
I solved it a few weeks ago by increasing my SoC Voltage to 1.280 in my case (AMD Overclocking). If I set the voltage lower than that, the lower I go the more chances I have of booting with the heavy stuttering. I have my memory set to 6400MT/s and tight timings.
If you suffer from this issue I would suggest increasing the SoC voltage. From what I've read, up to 1.3V should be safe.

Can you show a screen shot of where in the bios you raised your Voltage*(SOC). The fields are named different. Not sure if you are referring to the CPU or NB line. Are you using PBO with PBO limits x10 and +200 ?

Yeah, they've been working fine on A30 and the one before that that I don't remember which was. Yep, PBO x10 +200 and CO -15

Sure, this is the SOC voltage I'm referring to:

I'm using PBO as well indeed, with scalar x5, +200 boost clock and negative 33 all core curve.

I was rounding up 5.425 is the actual number. I did clear CMOS 3 times, after installing the new RAM.
The RAM is just running EXPO profile.

So far the mouse lag has only occurred 3 out of 20+ boots.


If it keeps happening I will turn down the FCLK OC to start with.
Yes, that's about right. I have a similar setup with an MSI 5090 Liquid SOC+ Carbon Wifi+ 9800X3d, and I haven’t experienced any issues, even with older BIOS versions. However, touching the BUS causes problems; even setting it to 102 makes my system unstable, so I avoid it. Adjusting the BUS affects more than just the VGA or general CPU; it also impacts SSDs, making it difficult to pinpoint the exact component that doesn't respond well. With three M.2 SSDs and a Soundblaster AE-5, troubleshooting becomes a bit complex and time-consuming. I find that leaving the BUS on auto and using PBO tuning works best for me. Like you, I'm reaching 5.425, and it works nicely. I also have Corsair TITANIUM 48GB 7200, but I'm running at 6400CL32 + 2200 FLCK.
As I mainly play DCS and sometimes have to be online and in the air for hours, I don't want my system crashing or being unstable, producing stuttering just to get an extra 100 or 200 MHz, which in reality doesn't even give a single FPS more. I was able to push my CPU to 5.6 GHz, or close to it, but it wasn't stable enough. While some games run perfectly fine long-term, others don't, especially DCS, which tends to stutter, freeze, and eventually crash altogether.
 
Thank you, so I found people using 'AMD Overclocking' vs 'Override' not sure what the difference is.
AMD overclocking you can let it deliver an "auto setting" (that would fluctuate and probably be a little more aggressive than the simple auto mode), whereas override is a fixed voltage. (you can also set a fixed voltage with AMD overclocking setting, but I don't see the point in doing that)

Try changing spread spectrum from auto to "enabled" and see if it fixes it. Doing that did for me.

I tested that to no avail due to the comments in this thread, both enabled and disabled the issue persisted for me until I increased the SoC voltage. I actually have spread spectrum disabled for a few weeks now and haven't had the issue.
 
Address Hash Bank + CS Enabled, Swap Apu
Maybe that was some issue with older BIOS? I see you're using build from January. I have latest beta (A41) on my Carbon and enabling first option didn't make any noticeable difference. Enabling CS and setting Swap Apu resulted in not booting.
Still trying to get stable OC system with this BIOS. Months ago I had old BIOS (A1A), got it to be super stable 10+h stress tests, but I didn't have tight OC.
A33 felt worse. now on A41 I can get up to 2h of VT3 in y-cruncher, most benchmarks similar to what was on A1A, but now with lower latency. I have a feeling that something with CO handling changed between A1A and A41, I have to reduce negative values to make it more stable.
 
This A41 BIOS update broke my Lian Li LCD wireless fans. Strangely, only one set of three fans connected in a daisy chain keeps disconnecting and reconnecting, while the other set of three works perfectly fine.

EDIT

I was stupid enought to not see that the data cable of the fans was loose.
Just updating you guys. Please disconsider this. The data cable came loose for some reason. Everything is fine now

EDIT------

I was actually right. The data cable wasn't loose. The problem persists.

Sorry, my bad, don't think always new betas are an upgrade, Address Hash Bank + Hash CS Enabled & Swap Apu they did something

Yeah, all new released Bioses are tricky and results can much vary, coz too much diff. cpu, mobo, mems in combo's are, too more diff. stability issues you'll find cause still imature Agesa's behavoir are going to be tested first on our rigs, before launch, no worries about new 1.2.0.3d will shown soon :censored:
It is a long term date I can only guess before a non-beta stable Agesa vers AMD will be able to fix in a final version for all our rigs, parts, scenarios & stuff, especially in mems OC nomad land DDR5 frequencies territory
Since I was flashed all new released Bios version, through I found nothing works stable with my same OC profile, I'll stick with A24 1.2.0.3aPatchA for my best one Profile setup (y)

Everyone writing about CO -20 or even lower, but I managed to get my 9800X3D stable on +200 boost only with CO per core, in range 0 to -12. I guess I had very bad luck with getting so bad silicone. Maybe I could get more from it with lowering boost, I see you have +150, or play with curve shaper. But when I tried that, I just made it worse.
I'll do bit more tuning and hope new BIOS will be available soon and get me some improvements.
This is current config... It looks like FCLK 2133 was causing some rare freezes, after I reduced it to 2066, mem benchmark is slightly worse (2%), but I did lower some timings and that reduced latency about 2%.
