Just a heads-up for those that purchased the "Hot Deal" Biostar Socket 1151 mobo a few months (more than a few?) back. I went and pulled out one of my G4560 rigs I build with it, and at the time that I built it, there were one or two BIOS updates for it. Now there's more.
Anyways, with the BIOS version that I put on there, that enabled using the Kaby Lake Pentium G4560 CPUs, I thought everything was Okey-Dokey, but when I tried that box tonight, and checked newest CPU-Z, I found that the DDR4 was only running at 2133. I looked in the BIOS, they had a "Custom" option, but it only went up to 1200. Thinking that was 1200Mhz / DDR4-2400, I selected that, but then CPU-Z told me that my RAM was only running at 600Mhz / DDR4-1200. Gah.
So, anyways, I flashed the newest 7/14/2017 BIOS/UEFI for it, and now under "Custom" for DRAM clock, you can now select 2400, and it works, according to CPU-Z.
Still no XMP support though.
Edit: According to the SPD data in CPU-Z, this is a DDR4-2400 (XMP) kit. So, on any normal mobo, should be able to select XMP and get that speed. 2400 is the native DRAM clock limit for Kaby Lake, so it should be able to do that speed, without enabling XMP, which is essentially what I had to do, but I had to do it manually.
Edit: Oh yes, there is no AHCI / IDE switch anymore for SATA - it's just not there. So if you have an existing HDD / SSD install, that was installed in one or the other modes, then good luck. I'm guessing that it defaults to AHCI. Btw, there IS a "Legacy (CSM)" Enable / Disable setting, that might be a way of re-enabling this after a reboot. I didn't try rebooting.
Also, there is a "Mining Mode" switch, which defaults to Enabled. I have no idea what this does - this board doesn't have a lot of PCI-E slots. (Maybe it enables some sort of PCI-E bifurcation on the x16 slot? Purely speculation on my part.)
