Played a bit with the XG-DLS. Dragged an industrial PC desktop case (this thing is heavy!) from storage, put that board into it, installed XP on IDE drive (later will use SCSI RAID 0) and test it.
As I feared in the beginning, XG-DLS is quite sensitive to PSU's. It would work probably ok at 100MHz bus speed but at 133 MHz VIO was at lousy 3.2volts and that was with Fortron 400w unit. Examining the XG-DLS I found out that it does not have on board regulated 3.3v supply (unlike other boards, like P2B-DS etc) where you can adjust VIO with pulldown resistors and on P3B-F there is even a jumper to adjust VIO (3.3v).
XG-DLS depends entirely on PSU in that regards so I needed to raise IO voltage.
On the Fortron unit I have rails are not adjustable separately so I used Chieftec 550W unit and set VIO to 3.5v with internal pot. That is helpful btw with BX chipset boards too, especially when all 4 DIMMs are in use.
Earlier the board was not stable at high loads (would lock up in the middle of 3DMark2001SE), now it passed it with flying colors. My 700MHz CPU runs perfectly stable at 866 MHz (6.5x133), had it running with Sandra burn.in test for hour or som, maybe later will test it on 933 MHz too unless I finish the 900 MHz CPU project sooner.
Tested different graphics cards, had Ti4600, FX5900 XT and Quadro FX 1100 (which is basically 5800). 5900 XT got 7300 points and Quadro FX 1100 got 7080 points so I left Quadro FX in as it smeed like more approriate for dual Xeon machine 😀 And it has green PCB which fits better with XG-DLS green PCB (5900 has blue PCB).
Many 3Dfx and Pentium III-S stuff.
