I got a new 256 Mb stick of Crucial cas 2 PC133 SDRAM and put that in my main system. I was able to overclock just a little past what I had gotten before, but only up to 952 MHz from 850 MHz. I think my problem there is heat related as I just have the retail HSF on the CPU and it is on a Slotket III. I could probably do more, but I don't really feel like messing with that.
Anyway, that's not why I started this thread. I took the 128 Mb Centon from my main system and put it in the 450 MHz K6-III+ that I have in the other room and started overclocking that beast. The board is an FIC 503+ which allows 100 MHz FSB and beyond but only settings for 112 MHz and 124 MHz FSB. I had overclocked the CPU (not locked) to 550 MHz before with the PC100 RAM that was in there, but only on the multiplier. The PC100 was generic crap that couldn't take the 112 FSB. So I put the Centon PC133 in there to see if I could get any FSB overclocking. I was able to overclock to 4.5X112MHZ which should equal 504 MHz right? Wrong - it posted as 481 MHz. Weird, huh? Then I decided to take it one step further and try 5X112MHz and instead of 560 MHz I got 556 MHz. At least that was closer. I tried 5.5X112 but this did not post. I then took the multiplier back down and raised the FSB further and tried for 4X124, but that posted but could not boot to windows. I guess the CPU didn't like the 24% overclock on the FSB or maybe something is screwy with the mobo at the 124 MHz FSB setting. Anyway, my new top overclock on that one is 556 MHz on a 450 MHz which isn't too bad considering I don't have a very good HSF on there and no Arctic Silver II. Oh well, I figured I'd post this and see if anyone had any ideas as to why they thought the 4.5X112 and 5X112 settings were so screwy. BTW I added the old PC100 RAM back in there and put it back at 5X100MHz so I am not living on the edge. Let me know what you guys think.

Me and the CMOS jumper became very good friends that day! Now I know better and have a nice, happy 107MHz FSB. Micron ram will do more, but the stick of Infineon that's next to it won't.
