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?
voltage was around 3.9V, didn't want to push it more. Second stick is worse about 5MHz less. RAMbooster isn't perfect, it has a vDroop of 0,05V under load even with 1*256MB stick. I believe, the most interesting clocks will be up to 250-270. Because after this you will have to raise tRD, disable PAT and CPC and it will kill performance of 865/875.
