Stay away from these motherboards. The USB 3 controller/ports are not working, a device connected will get randomly disconnected. I had to install PCIE USB cards to get USB 3 working. Seller not responding to any messages about the problem.
it is as described, quad-channel memory, I have an i7 4820k in it, running at 4.3 GHz with no problems at all, only downside is no cpu voltage control, so I can't go higher than that, a motherboard with voltage control cost about 4-5x as this, so can't complain, memory overclock works too,
