Thanks. Was looking in the direction of driver configs, and didn't think much about utility settings.
Can report nice results as well, not only is the card running the cooler about 15% slower with memory at 375MHz, but my PSU seems to have slowed its fan down to "idle" as well.
So, I guess I can make a recommendation for memory underclocking for those that are unaware of it (as a small way of making this thread a litte less redundant...
)
