Thanks, I see we're interested in researching the same things so I've registered to keep the info together.
pifast is a good idea! I will use it for the next tests too.Yes, latency alone might not always help. I use a combination of AIDA memory subsystem test (read/write/copy/latency) and Pifast. For example, CPC has small boost for AIDA but bigger boost for Pifast. Same for Tref.
My max FSB in 1:1 is ~273MHz. My other CPUs limit somewhere around 250-260MHz FSB.By the way, do you have info about max benchable memory frequency? I've been playing a several days ago and managed to complete Pifast on Winbond 1x256MB at 2-2-2-x at 289MHz (1:1).
With TCCD I couldn't get such clocks even at 3-4-4-8.
The max benchable memory, that I was able to get is 300Mhz in dual channel and with a 4:5 FSB : dimm ratio.
The max frequency, that I was able to validate ist 308MHz.
Pifast with 2-2-2-x / 289MHz is awesome! I wonder if you did this with a ASUS board? I mean, you probably needed a lot of voltage for this result and as far as I remember the P4x800 boards are tied to the 3,3V rail?
