Hi,
Maybe this is old news, but I have found a way to control the memory timings on the P4B266 after using the 3:4 trick described in some other post. The solution is pretty obvious actually: by using WPCREDIT and WPCRSET.
I have configured my timings as 2,3,3,6 (my memory corsair XMS3200 timings) by writing the following values in WPCRST:
Register 78h: 10h
Register 79h: 02h
The performance increase (in sisoft Sandra) is pretty small anyway: I have only noticed a small (2-3%) increase in the Dhrystone ALU benchmark. The other results in Sandra don't seem to change.
Hope this helps someone!
