anyone clockin over 103 fsb with cel 600+?

my 633 wont do over 100. probably will do 103 with more voltage but next step is 112 and wont even post on that. anyone?
 
What motherboard? I'm using a BH6, MSI slocket & Globalwin HSF, and I cannot go over 100Mhz on the FSB either. If I enable turbo for 103Mhz, I get all kinds of video problems (tearing, lockups). I have an ATI Radeon 32 DDR, and I'm wondering if it doesn't tolerate the out-of-spec bus speed very well.
 
Specs below. I've tried 112FSB at the hightest voltages, but it will only post and freezes on win95 startup window. Heat is not a problem. I'm thinking that my SB PCI128 soundcard might not like the overclocked pci.
 
I have a 566@875 which is a 103 bus and is stable. I can get Win98 to boot and run @112 but it isnt very stable. I have ordered some arctic silver grease (just using white goop now) so I will see what that does for me. I have even found that I can boot to winodws @117 using the 1/4 divider on my pci bus but then my agp bus is way out of spec (78mhz)and is about the same stability. I think I need more cooling (peltier??) but im not sure if my video card can handle an agp bus that high.
 
Bh6 is one i have. i dont know if that's the problem for me tho. cause i had 300a before this and it did easy 450 and even posted at 504 (112 fsb) but would freeze at windows boot up. I didnt feel the need and didnt use extreme cooling nor higher voltage then 2.1 to findout (2.0V is default for cel 300a) if it's a stable chip. im happy at 950 but just want to see if i can get more juice out of it hehe.

by the way i've noticed that the stock heatsink's clip was really tight and the chip was so thin. is it usually that tight? felt like it was gonna break that fragile cely2.
