New BETA BIOS 0902 out

[elmor]

Thanks for the cred, lol.

One bug on 0902 for me:

Fan Expert 4 totally doesn't work anymore.

Does the fan setting stick now in the BIOS at least?

Anyone else noticed deadly high cpu voltages?
On auto my cpu voltage jumps around 1.5V in idle. HWmonitor even noticed peek 2.8V.

Auto setting doest seem to have any limits

Which bios is that on? There's a problem with the readout (if your CPU wouldn't be running any more if it it was really at 2.8V). At default you could be seeing up to 1.45V due to CPB/XFR.

Also, need to remind people to keep SOC voltage as low as possible for now. Keep to 1.15V or less - and recommend using build 0902. This rail is very sensitive to overvoltage.

Running the exact same CPU overclock (3.8GHz) and RAM speed (2933) as with the 5803 BIOS, so I didn't lose anything there. Now I just need to see if I can get anything higher.

Not sure if I reset the bios after updating 5803 -> 0902

A couple of things:

1) Always flash UEFI (BIOS) at default settings.

2) After the flash the system will already be at defaults whether you perform number one or not. That said, you shouldn't update the BIOS with an overclock applied (at least not on this platform).

Yes, BIOS setting works, just AISuite in windows can only read the rpm, but not change them in any way.

One minor issue which is super low priority:
The PWM range isn't perfect on my EK Vardar fans, so i put them on DC control, because they become quite noisy above 35% duty cycle (on my old ASUS P8Z77-M PRO), while they're even a little bit louder on 18-20% duty cycle on the C6H, seems like the PWM is a bit wrong for me. I have them on case fan header 3.

@voltage:
If you guys aren't in OC mode, voltage shown is before the internal offset done by the Ryzen CPU. On Anandtech they figured out this one to be at 120mV. So 1.5V -> 1.38V true core voltage.
Only OC mode will disable this internal offset, so be careful not to compare OC mode and stock mode voltages.

Updated to this BIOS yesterday, but haven't tried pushing my RAM further yet.
CPU is running fine, occasional short spikes to 1.45V, at 1.25V most of the time.
The fans seem to behave a bit weird, as the CPU temp is a bit jumpy(Sitting at ~45°C in idle, and then jumping to 55°C or more when sudden load arises). So the fans have sudden bursts of noise all the time. Fan Settings in BIOS are at Standard, haven't tried Silent yet.
In general temperatures are stable though, ~45°C in idle, 72°C max under heavy load.

Had one half-system-crash when I Validated my system in CPUz, was forced to push the reset button as half of Windows refused to interact with me. No idea if that was a result of the BIOS Update, or just a Software issue.

Also seems like the system is less responsive when fully utilizing the CPU with Prime95 now. Moving windows is a bit laggy.

I'll hold off for the next bios as I havn't had any issues flashing, and I don't intend to flash any more bios's until the next version.
