Issues with ASRock AB350 Pro4 Motherboard - looking for other owners!

[bondisdead]

Hello! I was hoping to get some feedback on the ASRock AB350 Pro4 motherboard, with the latest P3.00 BIOS. In general, I have been very happy with it. Have a Ryzen 5 1600 CPU and 8GB (2x4GB) of Corsair Vengeance 3000MHz. Memory runs fine at 2933MHz, even under stress testing. Have not overclocked the CPU yet.

I am having a few issues, that I was hoping some users might be able to help me with. Just to see whether it's a problem with the board in general, or just mine. First off, if you leave the "AM4 training pattern" (or somethign like that on Auto, it will slow down the boot time to POST beep to 25-sec. If you set it to Disabled, that time is reduced to 10-sec. I guess I can accept this, once I am convinced my memory is solid.

The second issue is that if I leave that setting to Auto, the Restart to UEFI utility does not work. Machine will restart, but won't go into BIOS, and will instead skips to windows. I can reset the BIOS to default, then Restart to UEFI will work. It might have been with "AM4 training" set to Disabled, I am not sure, but there is some combination that breaks the utility. As a result, I can not set Ultra Fast Boot, or else I can never go into BIOS, and am forced to clear CMOS.

And lastly, I have Windows 10 Pro x64 Creators Edition installed. If I put the computer to sleep, it takes a full 35-sec before I am greeted with the login windows! Cold boot is actually faster! Even with default settings in BIOS, it will not improve this time. Even a different set of RAM makes no difference. I also tried another Windows 10 installation on a different SSD (Samsung 850 EVO vs SanDisk SSD Plus), and it was the same behavior.

Any help from current owners of this mobo will be greatly appreciated!

I have the same, times several. Except, one of my rigs has Team Dark DDR4-2400 16GB (2x8GB) 1.200V 14-16-16-36 memory, and the other several have Team Vulcan DDR4-3000 16GB (2x8GB) 1.350V 16-18-18-38 or so.

I can't get the Vulcan DDR4-3000 to boot at 2933, nor can I keep it stable at 2800, even if it does boot after a couple of POST attempts. I thought I had it working, by changing tRFC to 72, but that allowed it to boot, but I was still getting silent appcrashes, and sometimes, Windows crashes, where I would the the monitor sleep, and I would look over, and see the monitor turn on and go to BIOS POST. Some of that was Windows Updates auto-rebooting too, but some were apparently crashes.

Yes, there are delays at boot. No, I don't allow mine to go into actual sleep mode. I'm doing DC on them, which needs to be running 24/7 to crunch, so no point in sleep. Monitor is set to sleep, though.

Thanks for your reply! Guess I got luck with my Corsair Vengeance RAM, as it works with the XMP and no other tweaking! Next time you get a chance, do you mind trying putting the computer to sleep, then waking it up, just to see what the delay is? TIA!!

I've never tried turning off the training thing. Will have to give it A try and see if my boot time speeds up. I don't have mine sleep so can't answer that part.

On RAM I've had great luck. My ram is theoretically worst case scenario. Its crucial ddr4 2400 16,16,16,38. ITS also double sided 16 gb DIMMs which are not suppos4d to be good OC candidates. But with each bios update the memory has gotten better. I'm able to get it stable at ddr4 3000. It will actually boot and load windows at ddr4 3200 but crashes immediately she I try to stress test It. Still pretty darn good considering the ram I have.
