Hmm Gary even I the great plonker can see the nonsense do you think maybe it has something to do with the transfer rates from the Haswell to the RAM??
When I get chance I will run a memtest on the Sandy and Ivy and see what comes up. If your results are anything to go by it's a bit of a worry.
By the by there was some controversy a while ago on a thread I was in with memtest being upgraded from the one we are used to using. I think it was because it was in beta form or something like that.
