Here is an old A64/Vapo LS screenie that I found from back in 2006. It's too bad that I didn't get a higher shot as this was actually a 24/7 prime stable config that I used. I could probably have run 1M at 3.4GHz or higher.

Anyhow, this system is long gone so I can't rerun any tests, unfortunately. Sorry for the SPI 1.4, as I'm not sure if there is any difference between SuperPI 1.4 and 1.5.
