Since reading of the proggie from H.Ota at viahardware.com I've been trying to gather info on 4-way bank interleaving to improve the crappy VIA memory bandwidth.
I'm playing with a MSI Pr02-A which, in current beta-bios, has some support for 4-way if memory is set to SPD in the bios. ABIT and a few others impliment this better natively, but even this crude feature greatly improves performance with only one stick of generic sdram.
The H.Ota program allows many more variables and other features as well (such as settings for agp dividers not built-in on the MSI). When I receive the cas2 256 and 2 128's from Crucial I just ordered, I'll be able to compare the difference between a single and 2-stick approach.
It would appear that the memory bandwidth can be increased by as much as 40-70% with this low-overhead tweak, regardless of clocking.
Do any of you gurus have experience comparing 2 smaller to 1 larger sticks using this program for settings (or with more robust bios', for that matter)? There seems to be a lot of controversy on this topic (TS at Crucial think you need 4 banks of dimm filled to use it, which I know is wrong). Also, since miserable memory bandwidth is one of the few areas where VIA lags Intel, why hasn't Tom focused on there bios/software tweaks (you're losing that 'cutting edge', Tom!)?
