The chipset fan is noisy with the default setting. But you can set a custom fan curve for it and then it is inaudible. I personally set the chipset fan to 50% until 70 °C. In my experience that is enough cooling, the chipset stays far below the 70°C and it is silent.
Overall fan control is in my opinion sufficient, but not comparable with what old classics like Speedfan provide.
The RAM OC problems earlier Biostar boards had seem to be gone. Every setting you could want is available, including CAD Bus and Data Bus configuration settings. The latter are sadly not together with the timings settings, but buried in the "Advanced" tab. My personal results with E-Die are good (3733C15). MEM VDDIO and MEM VTT are not reported in Ryzen Master. RAM voltage can only be set as an offset to the 1.2V standard voltage. Up to (and including) ABB BIOS it consistently set the ProcODT value too low, causing problems to even load the XMP profile of my RAM (3000C15). Since ABBA that problem is fixed - at least for my RAM.
Things that annoy me:
- The CPU boost feels rather low, but performance is still good. 196 R15 SC is ok for a 3600 despite it not reaching 4200MHz during the run. Performance is ok, so I decided not to care too much for now.
- Default LLC feels rather aggressive. Changing it to LLC1 produces much lower temperatures and a slight multicore performance gain. SC stays the same.
- It reports wrong PSU voltages. It reports 2V for the 3.3V rail, 3.4V for the 5V rail and 3.65V for the 12V rail. FFS. That should never get through quality control.
- It does not report VRM temperatures or stuff like that. Probably an unnecessary feature as the VRM of it should be good enough for any AM4 CPU, but still - can not be that hard to display that value.
Thing that is seriously broken:
- The primary video device setting under "Chipset->Northbridge->GFX configuration->Primary Video Device" is not user enabled. With the 1004B Beta BIOS the mainboard tries to use my soundcard (Asus Xonar DGX) as video output. That does obviously not work. As a result: No post. Only fix I found so far was removing the soundcard. Lets hope they fix the bug. Otherwise I will have to see about either a BIOS mod or returning the board as defective.
That looks like quite a long list of problems, but overall I like the board. It got a very good feature set hardware-wise and is let down a bit by the software. Price/Features is very good. If the Bios gets fixed I can seriously recommend this board, otherwise I will probably be forced to learn how to mod the BIOS.
