BX Chipset 4-Way Memory Interleave Possible?

[DezMFNutz]

Is there any way to enable 4-way memory interleaving for a BX-chipset based board (Asus P2B-LS)?

I am planning to overclock a P3 750@1ghz, using a socket-to-slot adapter and a 133mhz FSB.

I noticed some nice improvements in SiSoft Memory Benchmark when I enabled this option on my KT7/Duron system.

Is it possible to use a program like WCPREDIT to enable it? Or is it a limitation of the chipset?

Thanks,
Rishi

I've never seen it switch on/off-able on any BX chipset board I've ever worked with.

AFAIK it mebbe is always enabled? RAM Benchies would suggest this...

I don't think that option is possible on a BX chipset. Probably due to how efficiently it handles memory anyway; I saw no mention of it in WPCREDIT.
But if you still want a decent performance boost, change Idle pipeline Dram leadoff timing from 1 wait to 0 wait. In Wpcredit, change the value (i dont remember the location but its in clear text), from "01"=add clock delay, to 00. If you use WBXTUNE, its a lot easier.

This should improve memory bandwidth by about 30 points.

Be warned that changing Idle pipeline dram leadoff to 0 when you alredy changed Leadoff command timing from "4" to "3" could result in an _instant_ reboot if your FSB is high.
