Maybe he was and the reference to patch C was just wrong, anyway, I would be happy if B550-F got the "real" patch C bios for testing as it's available for the other models

No, we don't mean bios 2407, we mean bios 2420 with patch C, which is available through overclock.net and hardwareluxx.de for B550-F WiFi, E, and XE, and the B550-Plus models. But not regular...

Yes, very irritating, the WiFi-version has it (version 2420 Beta) but not the non WiFi. The patch C bios(3801 Beta) works really well on my CH8 WiFi, most glitch free experience so far, of course I...

Because they are testing 3703 now, links in the other thread

1900 fclk has been working all evening for me, not a single WHEA, it's not the bios but rather your IMC or settings

Affirmative, been running 3601 since Shamino released it, haven't had a single glitch as of yet. Only difference to earlier bios was I had to raise DrvStr a bit from earlier bioses. 3800MHz mem,...

AMD motherboard forum on overclock.net, Shamino from Asus posts his test-bioses there, can't be more up-to-date unless being at Asus HQ. Considering you are confident enough to run a test-bios,...

Support is right, if you want low latency you can't have DSP. Realtime DSP effects are expensive and are not likely to be built into a motherboard.

For one, upgrade to the latest 2201 bios, it's better. For the second, I'm not sure the search function will find it as it is hidden under the AMD menus, under Precision Boost Overdrive, I suppose...

Was able to lower a lot of voltages, looks like a stable bios

Depends if you used GPT partition scheme or not, it only works with GPT

CSM needs to be disabled for it to work

No Gimping, just install the latest bios using Bios Flashback _before_ mounting the new CPU

I agree. I have ran my 5900X on both the CH7 and the CH8, very similar experience, biggest difference is CH8 has PCIE 4.0 which isn't a must have for most people. A good old Samsung 970 Evo Plus PCIE...

I have the CH8 WiFi, latest bios is stable for me but I have dialed in everything manual.

Things to look out for causing instability is FMAX should be disabled, too much negative Curve Optimizer...

It started with the V2 bioses for me, I had UR22C working flawless in USB 3.1 gen 1 mode and from those bioses it went disconnecting on both CH7 and B550-F. Switched to USB 2.0 and it works, but yes...

DOCP seldom works so far, setting timings/voltages manual works very well, so yes AMD is not for total beginners as of yet(unless someone helps them setting things up)

I remember a work mate who...

Well, it should be possible, maybe you have some secondary or third timing off. I only have four sticks on one of my mobos, it's a X470-Prime Pro with four sticks of Corsair Vengeance but old ones...

About 1.37-1.42V VDIMM, and VTT about 700-745mV

It's certainly not RAM by itself, but it can be FCLK behind these errors and it is coupled to the memory bus. As earlier has said, trimming SOC, PLL, SB, VDDP and VDDG may solve the issues.

I...

No, it has only two RAM slots and more high quality traces, it's for extreme memory OC.

Regarding the USB issues, I haven't noticed any with the newly released AGESA 1.2.0.0 bioses, that is on...

Problem is you need to do a lot of settings by yourself, D.O.C.P is usable only for a few.

I have four Ryzen systems running happily with 3800, 3800, 3200 and 3000 MHz memory. All far above their...

On further comment, this was a great question asked, it inspired me to find my "bad" core/cores. Turns out Core 1 on my 5900X is a lot worse than all the other cores, it easily spits out WHEA errors...

Glad you could fix it, but yes, basically if two cores needs more volt than default to even boot - your CPU is faulty. Bad QC from AMD. It may overclock bad, that would be ok, but not running default...

I don't know, I have a 3900X too, and a 3700X, both does 3800MHz memory with latest AGESA on B550-F and C7H
