Haha!!! That's what I'm interested in also. I just visited Microcenter and the guy supporting the CPU and motherboard section told me the 370 motherboards have been a horror show. Lots of returns and I guess they were expecting a bunch of boards but I guess a batch they were supposed to get was sent back due to quality issues. And yeah, everyone is complaining about not being able to get good memory speeds on their ram.
That's what I heard from a MicroCenter tech at the St. David's store. He said he had the C6H for a week and the BIOS issues were driving him nuts.
Obviously he had an interest in me buying a mb but I give him credit for steering me to this simple B350 chipset Asus Prime B350 plus. I told him I had 2 RX480s and a Ryzen 1800x sitting waiting for a mb. He showed me the $99 (before tax) Asus Prime B350 plus mb and said I ought to give it a try. He was right.
Sure my CF speeds are slower on the second card and it isn't a beefy card. It has only a basic Realtek NIC and it isn't built for heavy duty OCing. But guess what?
The sucker works. My rig is running.
As to OCng I booted into 4.o (40x 100) on auto but I really didn't push it beyond that AND I lost the built in OCing features of the 1800x which boosts 2 cores to 4.1 etc.
In addition, it is becoming quite apparent to me that the OCing headroom of the 1800x is VERY limited.
Once the Crosshair VI supply and BIOS issues get worked out I probably will purchase one to get better NIC and CF support.
That being said, this B350 mb is worth it for me (especially since I had a $50 gift card) so my out of pocket cost including tax and an extra $20 2 year replacement option from microcenter was $@70!
As I mentioned above I had trouble getting my custom water cooling setup to boot but I'm not sure that was me, late night build, anxiety or the motherboard. It became a moot point since I had a fairly new Corsair H110i GT cooler and plenty of GC Extreme thermal paste. When I hooked up the Corsair H110i GT and the sucker booted up I was thrilled.
BTW the M.2 slot works especially with the new uber fast NVMe PCIex4 ssds.I have a Corsair MP500 M.2 NVMe PCIe Gen.3 x 4 480g with AIDA64 disk benchmark scores of Linear Read-Begin=2315.5 MB/s; Middle=2575.6;End=2514.9;Random Read=2453.7; Buffered Read=2278.5; Average read access=.05ms
