Agreed. 4+1 setups can be ok overclocking but are generally sloppy with voltage regulation and not that stable voltage wise - tend to bounce around a bit. One note on MSI, after the black sockets were introduced it seems the quality of the VRM's went up. I toasted a white socket 890gxm-g65 on my first benchmark. The black socket version I have has been running for about 8 months without a single bump and has an overclocked 8150 @ 4.8ghz - 1.5V in it. Also a 1100T at 4.2ghz - 1.55V! However as stated, voltage is not very stable.
