The ASM1074 is a USB 3.0 hub, not a controller...
Actually, it's called a HUB CONTROLLER by ASMedia, so it's both in my books. Common part on many motherboards today.
Sometimes the boards I get from ASRock are early versions that do not have full functionality. I did receive one Intel Z77-based board from ASRock that should have had PCIe 3.0, for example, but rather than using PCIe 3.0 switches, it used PCIe 2.0 switches, so didn't actually have PCIe 3.0. PCIe 2.0 switches were very hard to come by at the time, so I rolled with the punches, so to speak, and that review was also posted with the board "as is".
The issues I encountered could be a bad board, or could be a problem with my stuff. I most definitely had a memory kit die in this board, the kit I use for all board reviews, and that's part of why there haven't been board reviews from me every week in July as I had planned. I also had my basement flood and spent about a week and a half dealing with that.
Board makers are always welcome to comment on my reviews, but unless complete stability is not possible, I do not often comment to board makers directly about the problems I find. If this product wasn't stable, the review would not have been posted, but because it was stable, both under OC and at stock, the only thing I can place the cause of the problems I found on is the BIOS itself. I have tested two other boards since this ASRock board, and did not seem to encounter the same issues, eliminating my hardware as the source of the problem, most likely, but there is still a chance that something is off with my CPU and memory.
When ASRock responds, I'll post an update.
