I increased the mobo's FSB by 1 point, from 152 to 153, and in doing so, I broke the 13000 barrier. Actually, this test is a bit daft, because I installed Windows ME for this "153 FSB" test. The previous "152 FSB" test used Win98SE. (I also ran the "152" test on ME, and got a score about 20 points less than on Win98SE.)
I tried 154 FSB, but this didn't work. 3DMark 2001 s.e. quit back to the desktop. It's not a mobo or caps problem. Instead, it's because the XP-M 3000+ CPU won't overclock beyond about 2.53 GHz, without experiencing some problems.
I do like this mobo. Increase its FSB, and you see a healthy improvement in 3D performance. I've just thought of a useful test. Rather than set the FSB to ~150 with an XP-M 3000+, I might try setting the FSB to ~160, and use a slower CPU. Begin Edit: I am stupid. Rather than use a slower CPU, I can simply use the same 3000+ rated CPU, and set its multi to a lower value. That can be done in software, using CPUMSR.exe. However, if it's possible to wire-mod these CPUs, then a different slower CPU would be preferable. End Edit.
Amigaz, maybe you could overclock your P4 rig, to break the 13k barrier?
