CPU arrived. Tried to boot from IDE to flash the bios, drive wasn't being detected. Booted into my old windows install (god I love that about 7, try that with feckin Vista) and in it went. Flashed the bios there...
PANIC.
The bios flashed OK. It rebooted with a beep, went into bios, saved, shut down.
Put in the 470. Rebooted checksum error. Into bios, set up what I could, rebooted black screen.
Cleared cmos, repeat above about ten times, started to get scared.
In the end I noticed the ram voltage was 1.7, miles off. The timings were 6 6 6 18 miles off (9 9 9 25 1.5v @ 1600).
Almost started crying from frustration and was just about to PM tom asking if he could ring me to help as I have absolutely no experience with these bioses.. In the end I found all the settings thanks to "overclock recovery" in bios that stopped it black screening and set it all from there. Also detected XMP (enabled) and the ram is 2T, now reporting 800mhz.
Time to begin a SSD secure erase and reinstall
