"Getting that out of the way, I can honestly say that this Mushkin Redline XP4000 memory is the best ram I have ever used on the DFI NF4 motherboard. I would highly recommend this ram if you have the voltage and adequate cooling."
003 makes a good point. I think that the OCZ uses (or used) TCCD ICs which are known to obtain high clock speeds with low voltage and therefore low heat.
BH5 ICs on the other hand, require a lot of voltage to OC (as seen in the review) and therefore heat up a lot. The only reason why the Redlines work so good in the DFI is because the DFI has very flexible voltage settings.
Did you not read the article? You're talking about if they are running at lower frequencies. Who cares then? The Mushkin clearly overclocked higher, look at the graphs. If you're a hardcore overclocker, the Mushkin is the way to go.
