I have the same motherboard, and the downloaded verified memory compatibility list. Kingston 1600 memory is only verified using two sticks at 4gb (2X2gb). The rest is triple channel, 6gb (3X2gb), 12gb (3X4gb), and 24gb (3X8gb). Your memory might work, it just hasn't been verified to work. Also, ASUS is using weird memory sockets, they only clamp at the top. It's easy to clamp the top of the stick and not have the bottom seated. It could be cocked, mine was at first and wouldn't boot. Check the side of the memory, where it plugs in, and make sure the top and bottom look like they are plugged in equally. If you don't find a problem there, try booting with only one stick in socket A2 (2nd socket away from processor), make sure the EPU and TPU switches are turned off, at least til you get the system running. If it doesn't boot, remove that stick and insert the other stick and retry. It wasn't clear to me, what you meant by , the cpu was found but the others (memory, hdd, video) were not. If you mean the led POST lights are only recognizing the cpu, my understanding of what the manual means is, those lights are only supposed to remain lit if there's a problem with that device. If the cpu light is the only one staying lit, to me, that means there is a problem with the cpu and the post would stop there. Make sure the fan plug from the H80 system is plugged into the plugin named CPU_FAN, and it has to be a 4-wire plug. If nothing is plugged in there, the bios will call it a cpu error and stop, so voltage isn't sent to a cpu with no heatsink attached, ruining the cpu. If you haven't found any problems yet, remove the water cooler, scrape the old heatsink material off the cpu very carefully, check the stock cpu fan that came with your processor, make sure the thermal compound is intact, and install the stock fan, til you get the system running without any problems. When I build a new system, I always try to start with everything stock , if I can. After I know the system works, I can modify one thing at a time. That way, if the system stops working, I know the problem lies in the last thing I changed. I hope one of these things gets your system working, I know the frustration you're feeling. You're not alone.
