I've just taken receipt of my Frio to go with my i7 950 and MSI X58A-GD65 that I got at Christmas. RAM is KHX1600C9D3K3/6GX. nVIDIA graphics (2xGTX260) Having tried BCLK of 200 and 16x multiplier prior to getting the Frio I had a few issues. One with the PC not waking from sleep properly, and very slow performance, which I thought was a voltage issue as I was very brief when trying these settings.
