Which Athlon XP Overclocks Better? 2000, 2100, or 2200?

Edit 3/21: All right, so I got the processor (Athlon 2200+), but I'm having the problem that is probably most dreaded by people who build their own computers. I can't get the mobo to post. I keep getting an error message saying that the "system failed memory test." I wasn't sure why I was getting that message, so I went out and bought new RAM to see if that would fix the problem, but I keep getting the same message. I ran everything at auto default settings first, and then tried setting the FSB manually at 100, 133, 140, 150, and 166 MHz. Nothing works. I tried auto, 100, and 133 MHz FSB on my Duron, and that doesn't work either now. What's going on??

Here is a thread I started that lists some more details of what I did:
Computer post problem


Edit 3/18: OK, it's clear that the general concensus is that the 2100+ tends to o/c better than the 2000 or the 2200. But since I'm looking for a retail chip, my question just comes down to this right now: which is more likely to do the 133 to 166 MHz jump for its bus: the 2000 or 2200?
------------

Is bumping up the bus from 133 to 166 MHz on the XP 2000 and 2100 a relatively easy overclock that is practically guaranteed to work with a decent heatsink (I have a Thermalright SK-7)? How likely is this same overclock with the 2200? I'd prefer to get a retail version of one of these processors, and since a retail version of the 2100 doesn't seem to exist, I'd like to go with the 2200 if my chances of overclocking the bus from 133 to 166 are very good. If it's not, I'll have to go with the 2000 instead.

(Side question: What is the limit to the number of posts that people with free accounts can have? What's the time frame that the limit designated across--1 week, 1 month, etc.? I can't seem to make posts once in a while and heard about a so-called "speed limit"...)

Well, I can tell you my experience with two of those.
First my 2100+ retail w/2200+ HSF wil do absolutely ZERO on an OC.
My 2200+ retail w/2500+ HSF will OC at 2.000MHz 166 X 11 and a 1.80 vcore. I had had it as high as 2.09MHz with a 166 FSB but it was not very stable, temp gets to a max of 56 C.
I was also not too impressed with the jump from 133 to 166 (as far as Sandra goes) 133 (1.80MHz) gave me scores of 6665 and 2683 cpu and 1940 and 1811 ram. 166 (1.833MHz) was 6794 and 2722 cpu and 2447 and 2250 mem.
Mem got a pretty good boost but I expexted more of a jump from the FSB.
This is on an A7N8X and Samsung PC2700

I'm pretty surprised about the 2100+ not being able to o/c at all. When did you buy these processors? Do you know what CPU steppings you had? I see that you had to unlock the multiplier for the 2200. Does anybody know of a good website that teaches you how to do that? Thanks for your help!

The multiplier is unlocked on NF2 boards. I picked up both chips about 13 months ago. I had the steppings written down somewhere but can't find them at the moment. I posted a ? about the 2100+ and folks here told me it was not the best

Hm... I thought that when people talked about unlocking the multiplier, it was done on the chip (i.e. there was a bridge to connect). Maybe the chips you got were factory unlocked? Or are you saying that NF2 boards are able to override any locking done on the chip?

Can I get some more help please? What do you all know about the overclocking potential of these processors? And does anybody know whether or not there's a limit to the number of posts you can have within a certain timeframe? Once in a while, I get error notices saying that I can't make posts, so I'm trying to figure out why.

From what I've seen, unlocked 1700+'s and 2100+'s are the best overclockers as far as cpus with the t-bred b core go. Try to find a 2100+ pre week 39 with the AIUHB stepping. You should be able to get 2.4ghz or higher EASILY with that sk-7 (as long as your motherboard, ram, and airflow in your case are nice). The main thing is getting a nice stepping on either a 1700+ or 2100+ and making sure it is pre-week 39 so it's multiplier is unlocked.

I just bought a 2100+ from newegg less than 2 weeks ago. See my recent post (2100+ in title). Long story short... 2100+ @ 2.2ghz @ stock voltage w/ retail 2500+ heatsink (not the one w/ the copper bottom the old one that came with early bartons). BTW... this was also on an Asus A7V 100mhz fsb circa 2000 I believe. From what I hear and read 2100+ are some great overclocking chips. BTW mine was a week 18 of 2003 :)

I have a 2100 Tbred that easily went from 266MHz to 333Mhz with a small voltage bump. I'm at 2.0GHz for stability reasons on this system which is fast enough for the apps I'm running. My gaming system is another story.

I get 2.47 Ghz on air cooling with a KT266a and AIUHB XP-2100+. I got the exact same with the 1700+. In my opinion, they are as close to equal as OCing goes. The 2000 and 2200 are not generally thought of a being as good as the 2100+ or the 1700+.

I had a XP 2000+ that overclocked well 170fsb x12 multi [AIUHB 0317] @ 1.70V
Got the chip from AMD. Had to RMA directly with AMD

Hey guys... just wondering... are the new tbreds locked? I know the week 39ish and later barton's are... but did they lock the lower processors also? I was under the impression that they did - just wanted to confirm???

Yes, most if not all of them after week 39 are locked. Some between 39-43 may be unlocked though..

i had a problem with not being able to post for some reason. I always thought it was because of the computer or some settings on IE or something (cause it only happened on my sis's PC). Then I tracked it down to the fact that I was using AOL to post.

I can post on road runner, anytime no problem. Soon as I use AOL to sign on, I cannot post. Is there a reason for this?

Wow, I'm glad you brought that up. I never thought of the ISP as being an issue, but I think that just might be the answer. I just tried posting while being connected to Compuserve (which is owned by AOL), and I was denied. Anybody know why? There must be a reason...

Anyway, yes, it does seem that overclockers prefer the 2100 over the 2000 and 2200, but since I'm trying to stick with a retail chip, do you all think the 2000 or the 2200 has a better chance at hitting 166 MHz in its bus? If it's about the same, I'll try the 2200 and see what happens. Otherwise, I'll just stick with the 2000. If both of them are horrible with overclocking, maybe I'll go ahead and try an OEM chip from NewEgg.

Thanks to everybody who has posted so far. Your suggestions are very much appreciated!

That's right. Theoretically the moblie t-breds should even OC more than the moblie bartons because of less cache. Get a 2100 or 2200 moblie which is 1.45Vcore defalut and I bet an easy 24-2500 MHz.

That's an interesting idea. Is compatibility with the mobile processors guaranteed, or is there a distinction between desktop processor and mobile processor compatibility? The only info I can find about my mobo right now is that it supports up to 3000+ with the latest bios version.

If your motherboard supports T-breds, then it will support a mobile T-bred. Same with the Bartons/mobile Bartons.

Bump for the update. I'm having a problem getting the computer to post now, so any help would be greatly appreciated!
