Well im extremely disappointed to say that the new 2700X has not fixed any of the boot problems I had before with the 1700. Even though I was told time and time again by people on forums and by ocUK staff that the problem was not the motherboard, but most likely a crappy IMC on the CPU. So either im the unluckiest person on the planet, and I've got another dog of a CPU (thanks ocUK) or my Crosshair VI is actually the culprit in this nightmare.
All I've done is set my memory to 3466 (TridentZ 3600mhz kit) and set the stilts 3466 profile, and reboots with an F9 error. I'd accept that if it wasn't for the fact that this setting worked fine last night (after my system had been on all day)
Anyway, eventually, after enough reboots, it will get past F9 and then stop on 7A (no idea what this is, it's a new one with the new bios) but it used to always stop on 54/55 with the 1700 in. So i'm no further forward.
