tony - maybe try to isolate the problem?
Turn the mutli's for cpu, qpi, uncore and ram as low as you can - then start raising block - you shoud be able to get to 200 or better!
turn multi's to -
cpu - x16? - if it will go this low?
qpi - x36
ram - x6
ram timings on auto.
To make sure voltages are not your problem - set voltages:
cpu - 1.4
qpi - 1.34
dram - 1.64
make sure all the c's and eist are off.
maybe start with HT off
start at a bclock that has worked before and move up from there.
Once you know your mobo's max bclock you can move on to memory or cpu ocing.

I have already tried cpu x17,x18 and x19 ,qpi x36,ram x6,unicore x16,17 and 18 ,these settings will not post correctly ,get the restarts then the overclock message above bclk 172 .I have also already tried those voltages they make no difference.I can't understand how other people have easily got bclk 180+.
I have noticed the auto setting are qpi=36,ram=8 and unicore=20.All cpu power management is always off.172 is the max i can get ,its not stable in vista anyway (freezes) also freezes in the bios.

I have just accepted i have a bad board/cpu.I might mess with the corsair mem sticks later (swap them over try dual and single channel etc).Also i might strip the whole lot down and run outside the case with 1 hard,video,ps2keyboard and mouse and 1 stick of memory.I guess i am unlucky this timeI have spent about 20 hours on this and never had such a hard time overclocking ,i started with a vanilla pentium mmx all those years ago.I used have a mach2 - loved that and loved the massive overclocks.

Thanks for your help i do love this forum!

You only need the uncore at twice the memory, have you tried just x12 UCLK with x6 mem?

Yes still getting problems.I may order another i7 920 soon.
