I've been running a pair of Duron 1G on a TigerMPX for about 2 weeks now and haven't had any problems. I even have them running at 133fsb. It was risky but I cut the last L3 bridge with a box cutter on both processors then used a pencil to join the second L3 bridge to get a multiplier of 9. The processors now run at 1200Mhz (9*133) at default voltage. I tried running them at 10*133 but I can't boot into windows. Probably because I'm using the retail sinks. When I can afford it I'll get to volcano 7+ processors and try to up my fsb some more.
I just wanted some cheap chips for now until the T-breds come along and they are performing great. I just checked out an article at mods4me.com today to squeeze even more performance out of my memory. You prolly only need wpcredit if you have a Tiger MPX since I heard that the other boards are all tweakable.
My system is as follows.
Tiger MPX (non functioning usb)
Dual Duron 1G@1.2G
2 256mb Crucial PC2100 Unbuffered
Leadtek GF3 TI200
Some cheap ancient yamaha software sound card
Lite-on 24x burner
Pioneer 16X DVD
Enermax 330W
Adaptec 29160
Atlas 10KIII 18GB
IBM 18ES 18GB
WinXP Pro & Mandrake 8.2 dual boot
I should have a Santa Cruz by next week, I might get an IDE drive for storage and I'll upgrade the powersupply when I get more dough. I'm really taking my time trying to build a really fast system. It's taken me some time to get there but I'm almost done. The system is running fine so far with not 1 crash encountered so far. It feels great not having a VIA board anymore.
