The timings will depend on your overclocking- if you get your FSB up fast enough, you might have to loosen them from CAS2 to CAS3, but at the moment, default timings are probably about the fastest you'll get- I doubt it's fast enough for CAS 1.5, and playing with the other numbers won't really help your bottom line; they're more a means to achieve it. Being 3700, you might be able to keep them at CAS2 at higher FSBs that I was able to with my 3200
...which begs the question- why is that rig not overclocked yet??
I got 55 seconds with my Mobile Barton 2500+ at 1.8GHz. Its been overheating recently since its been hot here and cause I can't get my stupid SLK-900 to cool worth a darn, so I put it at stock speeds. I'll try and put it back up at 2.5GHz sometime soon and let you guys know what I get. I think when I ran it four months ago I got a best of 45-46 secs at 2.5.
I have been kinda made the admin of a room of 9 1800XP's on an MSI KT266 chipset platform. I must say most of the time the machines run very nice but they still have some really weird dang problems like all of a sudden the USB mouse quits working out of the blue.
