Wierd overclocking with my new 2100+

I just got my new CPU today.

AXDA2100DUT3C
9727074260738
JIUHB 0308UPMW

I'm having a few wierd problems. I like to keep my system at around 210 on the FSB. The CPU boots no problem at stock voltage at 9.5x210=1995. 1.65v brings Prime95 to be error free. Well I thought I should try for more, of course. So I brought the FSB down to 200 to see what I could do with a multiplier of 10. Boots right up. Boots at 202 which is 2020mhz. But it will not boot at 203. I bump up the voltage all the way to 1.85. Nothing past 202x10.

Well I've concluded that it's not a temperature or CPU problem. I'm running at 140x15=2100 right now. I just set the voltage to 1.75 to play around so I don't know if it will run at this speed with less. Anyway, I'm not sure what the problem is. Any ideas?

BTW, I've already had some discussion of this in this thread.

BTW, I'm at 36C typing right now. Load would probably around 41-42C.

Now I'm at 2205mhz with 1.75v. I haven't tried lower voltage.

This is 147x15=2205.

I think I'll try to get 200x11 since I know I can hit this speed now. It's weird. The FSB is not bothering the CPU as it can run 210x9.5.


UPDATE!
200x11 works!!!

I'm at 2200 right now with 1.75volts. I think I leave that alone as I'm sure it could use the voltage at this speed.

It must be something with the 10 and 10.5 multiplier that was holding me up.
