AMD 1.2 gig

Hi all
some how I can't get my cpu to overclock higher then 1391 stable
1404 I get but not stable ( my temp is 42 idle and 46 load)
custom Heatsink and delta balcklable Delta fan 7200 rpm

my SYSTEM got the following
AMD 1.2 @ 1391 13X107 (AXIA 200fsb)
512 MB Pc 133
Nvidia GTS2 64 MB 216/400
Maxtor 30 gig 5400
52x/8X4X32
MSI K7T Turbo/VIA KT 133 A Bios Ver 2.9
1.8 and 3.3 V
I can't change the FSB to 133...I got the option with a jumper but my system don't boot if I change it......my options for multiplier are 12,13,14,15 v = 1.55 -1.85
i got no lower then 12X I guess that is why I can't run 133 Fsb
my chip is unloged
can anyone give me some info on how I get stable over 1400

thx for helping me out

Have you tried to give it some more voltage?

Yes i uped it to 1.85 the highest I can go wih my board ...still the same 1391 Mhz stable 1404 and up don't work 1404 works one time but after I reboot system freezes

Have you done some burn-in?
I was stuck @1410 whan I first started to overclock my T-Bird, but after some burn-in I got it higher, and now I'm at 1470 and testing 1501MHz

Im currently at 1530 stable at v1.89


but I have a 1.2 266 instead of a 1.2 200
