When i booted up I then got stuck! - It refused to boot. Tried this four times in a row - eventually it booted. Tested it again by shutting down and starting up and worked fine this time.

Looks like my booting issues aren't just overclock related!! grrrrrr..Can't be my memory as I've had two different sets in here - one Mushkin the other Corsair. Can't be overclocking as I get the same. Can't be the CPU as I got the same with my 2600k and now my 2700k. Only leaves one thing - the mainboard!

Come on ASRock - give us a new BIOS before I return this thing!
Must admit I am begining to wonder about my ext 7 gen 3 as well, but for slightly different reasons(Bios maturity to one side for a mo), I have had a 2600k and a 2700K - the 2700K supposedly from a good oc batch.
Yet I am finding like yourself that heat is more of a problem than volts, but I am now wondering if the power/voltage control of these Asrock boards may be somewhat less than stellar, as I keep hearing stories of people geting
easier and better o clocks with less heat and hassle on more mainstream boards, and better quality boards??? What is your view on this - as even under water I am struggling to keep temps down. For example my 2700 will do
4.5Ghz atr a modest 1.288 volts under Linx test + other tests stable, but in a cool room under good w cooling temps are still 66-70 degrees,so I feel I dare not attempt higher,although i think 4.6 will be just attainable.
I have made all usual checks for air/re seats of block etc etc, but no dice.Starting to suspect that although these boards give you a lot of features, and are good value in that sense - is it at the expense of good quality power/voltage
circuitry, and bios???? Where next I ask myself?????
