My experience with Dual Pentium boards so far has been that dual-MMX will always be a problem... MMX processors use a lot of power, and most of the dual boards can't take that.. you should also see to it that you have a power supply in your computer which is capable of supplying enough power to all the components you use (which was one of the problems which I stumbled upon) On Mon, 19 Oct 1998, Norbert Lesch wrote: > Date: Mon, 19 Oct 1998 17:36:41 +0200 > From: Norbert Lesch <[EMAIL PROTECTED]> > To: "[EMAIL PROTECTED]" <[EMAIL PROTECTED]>, > [EMAIL PROTECTED] > Subject: Asus P55 T2D4P, Problems with Cache using smp-linux > > Hello SMP-users, > I use the Asus P55T2P4D (dual Pentium PCI/EISA) mainboard, 128MByte EDO > Memory (4*32MByte), 512kByte 2.level Cache Module Asus CM1 Rev. 1.6, > 2 Intel Pentium233MMX Processors, stepping 3, kernel 2.0.35, symbios > 20810 SCSI controller > > The Problem : > In single CPU mode the board is stable (that means 200 kernel compiles > using make -j without an error), no matter which CPU of the two is > used!
