Tell us about your cooling, BIOS settings, hardware, etc... that's a pretty ambiguous description.
Thats funny you bascially had the same problem I did.
I just bought a 2500+ XP barton and overclocked it to 200 right away. What I did was kill winXP after it would not boot into it. I had to do a complete reinstall! I also had to reset my CMOS.
Bascially in order to boot into it with a FSB at 200 you will need to raise your voltage to 1.7 or 1.75, maybe higher. My computer would boot into XP at 190 stock voltage, but it was not that stable. Right now I"m slowly raising the FSB I'm at 190 now also at 1.7 volts.
Many people on this board make it seem that you just buy a barton 2500XP, and you will get 3200XP speeds by upping the FSB to 200. They don't do it on purpose, but they do it. You will need to take your time and do it slowly, also You must download prime95 to make sure your board is stable. Even when I was able to boot into 200FSB by upping the voltage it was not stable at 1.75 volts, When going into wolfenstein my computer would crash out of the game in a matter of seconds.
So just take your time, play around with the v-core and bring it up slowly. Patience is the key especially if its your first overclock, as it was for me.

Sorry, I should have thought to check your sig, but it doesn't show up in the "reply" page. 
I don't know anything about that board/BIOS really... but you could try turning up the chipset voltage a little. Also, is your RAM set by SPD or manually? For stability purposes, set it by SPD for now, because it should be able to run at 200MHz but not necessarily at timings set by the user. What's the CPU's voltage set at by default?

suprropmp, so far how do you like your new system? What did you have before?
I have similar, 1 gig mushkin level1 ram, DFI infinity motherboard, Silent boost CPU cooler, Barton xp 2500+. I wanted to get 3200 speeds but not sure if I will be able to yet.

I havent touched the agp settings (i believe its on auto.. should i touch that?)
eddie: So far i love this new set up. I'm a little disappointed b/c I couldnt get the 10000 rpm harddrives but the 7200 w/ 8 mb cache seems to be fast enough. Before this I have a PowerMac G4 433 mhz and a 1 ghz amd athlon HP notebook (along with another 1 ghz amd set up that I never use =/).
Originally I was going to get the 3200+ as well but I figured it would be more fun to try to overclock the 2500+ (didnt come out too much cheaper because I had to buy this monster hsf)

i honestly did that, i got the chip, stuck it in, went to the bios, changed it to 200FSB (first time i ever got the fsb that high, normally ran old chip at 185fsb) and set the vcore to 1.7, and never looked back once - booted right away and rock stable ever since.....
I must have got lucky with mine, I am running a A7N8X Deluxe Rev 1.04 with Uber BIOS 1004 and I was able to get my 2500 to 11x200 @ 1.65v. I have succesfully gotten the machine to POST at 12x200, but Windows would not boot. so I dropped it back down to 11, and it has been running stable ever since and the BIOS recognizes it as a 3200. Ran Prime 95 for about 16 hours with no errors whatsoever. The 2500's can sometime be hit or miss, I have read on other forums of people using 2500 mobiles and clocking as high as 2.7 ghz! Good luck man, it's a good chip and well worth tinkering with

Look, you need to go slowly.
Your cpu and memory may require any combination of bus speeds, voltages, multipliers or timings.
Keep all other variables the same, and change each of these parameters slightly, increasing only when you have determined them stable. Adjust accordingly.
I would suggest leaving the multiplier alone, and increasing the bus speed slowly from the default, since you know your MB and memory can hit 200 FSB (according to MFG specs) the limiter would be your CPU...go slowly and if you hit instability at a point, slowly increase the voltage.
Once you find out the voltage you need to hit 200 FSB, you will need to start playing with the multiplier and overclocking the bus and memory.
They key to all of this is
1. Go slowly (especially with voltages!)
2. Change one variable at a time.
You can do it! You just need to find the right combination.

would it work at 12*200 with a higher vcore? cause the performance boost would definitely be worth it.... 2.4ghz<<<<2.2ghz (especially with these AMD chips and their really good cores)
Well what I can determine is my max overclock seems to be at 195. At 195 vcore 1.7 its rock stable.
WHen I push to 200FSB, up the vcore to as high as 1.8 lower my timings IT just boots into windowsXP but then crashes as soon as i run prime95, or play anygames.
Its wierd that I can hit 195MHZ Rock stable at 1.7 (maybe even 1.65) But if i go up to 200FSB it just can't do it. Well I'll be happy at 195, better luck next time.

your problem is that your ram can't handle those speeds. you need to either a) raise the voltage on the ram (you should get some cooling on them though even if it's passive) or b) change your bus divider to 6/6 or something like that. Just try to keep your ram slowed down. You might even want to try to raise the latency but then overclocking is a moot point except saying you got some monster overclock.

i have a barton 2500 and an Asus a7v600, the mobo gave me 2 speeds the barton can run at, 2500 and 3200, i just set it at 3200 and its been working dead solid for the last 4 months, no voltage change.. NOTHING, i dunno if i got some strange luck with my current setup or what, ive never been able to OC that easily
Don't feel too bad, I have Corsair XMS PC3500, an A7N8X Deluxe 2.0 1007 and my XP2500 fails Prime at FSB200, I'm running it right now at FSB195 which I've primed for 10hours and there weren't any errors. The voltage is around 1.792 - 1.808V.
2.15GHz is still nice and fast although Windows boots with all programs fully loaded around 3 seconds faster with FSB200 (40seconds but I think this may be to do with my RAM more than my CPU) but there is no real difference in games, office etc.

about 54 or 56C after a 10hour Prime session but that's with my PSUs QuadFans set to it's lowest mode and my Aero 7 lite set to around half RPMs, also my airflow is pretty bad and I didn't apply the thermal paste properly so at this voltage you could probably manage lower temps. I read it's safe to run AMDs in the 55s anyway so I'm not too bothered, the highest I've ever got it while gaming is about 47C (with Fans set higher), infact it's 47C right now and all I'm doing is browsing the web and listening to and downloading some music. Also my A7N8X overvolts like crazy, it's set to 1.725V in the BIOS so I'm getting nearly a 0.1V overvolt. I made a thread a long time ago to collect peoples voltages for this chip while running on air cooling and 1.8V seems safe enough, there were a few who had the chip for about 6months running at around 1.9V on air, most had theirs set to around 1.75V.
Who really cares about running high volts or temps, its an $80 dollar CPU, just buy another. Especially if your pissed about it having shit overclocks.
I not saying run 2.1 volts, 1.8 volts is totally fine.
ALso I get a load as high as 63C when running prime95. The temps really matter though based on your ambient temperature. FOr instance my room in the winter is in the low 60's, and in the summer as high as low 90's. MY CPU temps flucuate hugely based on the winter or summer. I'm talking 30C with low fan settings vs 50sC with highest fan settings and faster fans.
So if someone says I have 28C Idle temps ask him his room temp.
