Underclocking the RAM to the next lowest speed completely addressed the issue. If i get keen i may re-visit the RAM timing to see if it can be made to run stable at the nominal frequency with more conservative settings on the other parameters.
If the firmware hasnt fixed it, the underclocking is cheap test, but yeah power supplies seem to be problematic. I always buy branded ones, but even then only had mediocre results.
