    Counterintuitive memory setting

    Nifty little trick for those overclockers out there.

    Originally had my t(ras) setting at 5 which was the lowest my mem would support, and I thought that would also be the fastest setting. After reading a guide, I set the t(ras) to 11. Booted into windows fine and better bandwidth. Went back and was able to overclock the FSB another 4 Mhz. All perfectly stable. So setting t(ras) to 11 netted me 100 MB/sec mem bandwidth and another 50 mhz headroom on my cpu. Apparently the optimal t(ras) setting varies with fsb, for 200 Mhz 11 appears best. The lower the fsb, the lower the optimal t(ras).

    Worth noting, I'm running an 8rda+ rev 1.1 with hyperx pc3000 memory. YMMV with other chipsets.
