No difference with the 441.66 drivers.
Going to change the PSU to a more powerfull unit, see if that works.

I’ve got a HX1200 Corsair PSU – it’s Platinum efficiency (so 1150Wish) and the cards have a rated TDP of 285W each (they’re ASUS TURBO versions). So even loosely with a 165W TDP CPU (No Overclock)

3* 285W = 855W + 165W = 1020W

I realise there will be fluctuations, but likewise, everything won’t be ...

Just tried the MSI option but no joy, still crashes when all three cards are enabled.

Thanks Juanjgon,

I'll look into that.
