Hmm, I'll have to check that in the BIOS. If the voltage is reduced in the newer BIOS, that could be why I'm getting a power state fault and BSOD. I may try a new BIOS and set the voltage manually. Thanks for the idea...
What's your SoC voltage?
My ASUS TUF X670E Plus WiFi before and after BIOS updates
My old BIOS 821.
Latest BIOS 1414
Based on EXPO II, I tightened the memory timings with BIOS 821 and 1414.
I skipped all the BIOS releases between 0821 and 1414.
I was reading through the comments on this and would like to comment on the x8 3rd slot. There are scenarios where that would be a great value;
1. You are getting a 7000 series APU and want to maximize your storage. We know that AMD likes to GIMP the APUs lanes so you don't get the full 16 on the main slot anyway. Well you could still have a 4 way RAID 0 or 2 RAID 0 arrays to take advantage of direct storage across the top 2 slots. If down the road you get a current GPU you could easily put it in the 3rd slot (barring size) and not really lose any legible performance as 5.0 x4 is the same as 3.0x16 but importantly the GPU has 8 physical lanes to communicate with.
2. You already have a 7000 series chip and want more storage, that will not be heated by your GPU. You could spend big on Amazon and get a (probably) used Enterprise NVME with a controller. There is however a special product on the market. The WD AN 1500 which is much better than any expansion card. You see it has a Marvell controller on the PCB. That means that Windows sees that controller first and that controller tells Windows how much storage it has. Now you could spend $1100 on the 4 TB or buy the 1 TB for (Currently) $281.47 Canadian. You could then take 2 of the Kingston NV2 2 TB drives and have a over 6 GB/s 4TB NVME for under $600. The WD AN1500 will work in any slot but will reach it's full potential in a slot wired x8.
Realistically the Ace is the only MB lineup that allows you to do this. The X570 Ace, Unify and X570S Ace all are wired as x8 on the 3rd slot. When I make the jump to AM5 it will be this board that I will be using. Besides that fact that to me the board is industrially beautiful. I absolutely love my X570S Ace Max. Even the little things like the post code LED being white. Against that Gun Metal surface, it pops nicely.
All desktop Zen 4 SKUs are APUs i.e. they include IGP 2 CU RDNA 2 @ >~2.5 Ghz with 128-bit DRR5-6000 beats any old Ryzen APU with Vega 3 IGP and 128-bit DDR4.
From
https://www.msi.com/Motherboard/MEG-X670E-ACE/Specification
MEG X670E ACE has the following slot specs
3x PCI-E x16 slot
Supports x16/x0/x4,
x8/x8/x4
PCI_E1 Gen PCIe 5.0 supports up to x16 (From CPU)
PCI_E2 Gen PCIe 5.0 supports up to x8 (From CPU)
PCI_E3 Gen PCIe 5.0 supports up to x4 (From CPU)
X570S Ace's 3rd PCIe 4.0 X16 slot with active 8X will be bottlenecked by PCIe 4.0 4X lanes link to the CPU unless MSI grabbed PCIe 4.0 4X lanes from the CPU and combine it with X570's southbridge's PCIe 4.0 4X lanes. The X570 SouthBridge link to the CPU is only 4X lanes PCIE 4.0.
