    8 Hrs plus Prime Stable (blend), 20 runs Intel Burn Test at max stress
    3DMark06 and 3DMark Vantage stable (no freezes, lock-ups or bsod).
    Max CPU temp recorded were 78C using IBT and 69C with Prime. All tests backed up by pics if anyone interested.
    Warning - These settings are for water cooled cpu and NB.

    Next step is 471x8.5 stable (to break the 4Ghz barrier for a cheap quad CPU!) with the g.skills limited to 1570 as there is no way they will work above 1800 Mhz (will need better memory for that - wish I had the corsairs ).
