AMD Athlon XP Bartons, 400FSB or 333FSB?

Now, earlier looking at NewEgg, I saw that they had two 400FSB Bartons in the 3000+ and 3200+ speed ranges, which is 2.1Ghz and 2.2GHz, for $264 and $445.
Seeing how prices can go down, should I get a 400FSB Barton, or get a 333FSB Barton and overclock it to 400FSB with the NF7-S v2.0 I plan on getting with it. Right now, its a 333FSB XP2800, 2.08GHz Barton that I plan on getting, which is $173.00 at the moment

Since you are going to get an Abit NF7-S rev 2.0 you may want to consider getting one of the new 2600 Bartons from Newegg for $99.00. Equito and some others feel they may well be the Bartons to O/C. I see no reason to spend the extra money when it is no problem to get at least 3200 speeds out of a 2500 and these should even do better. Basicly with an NF7-S all Bartons will be 400 capable.
Are you certain? What do you have to back up that they are exactly the same? I really doubt it as all the higher end chips are made with wafer from the center and only from certain batch productions. The 2500's are from the outside edge of the wafer and don't have the capability to be as stable. While I am not an AMD production engineer I am not stupid in regard to how they derive their different chips. Lets take an xp1700 for example. We know that certain designations generally O/C better than others. But not all JIUHB'S will do better than all AIUHB'S. One big reason for this and it is the reason some people get a "Wonder Chip" is that after AMD meets the required quotas for the high end chips they put the leftovers into "the pot" so to speak. From what I understand from the buzz Equito started, and I generally put a bit of stock in what he has to offer isthat the 2600's are coming from a new production that is supposed to be of a higher quality than previous chips.
Also, the 1800+ (Retail) is $58 right now and I got one of those a couple weeks back that is a DLT3C that a few people believe will push 2.3 or higher. It isn't my personal chip so I can't O/C it to be sure, but for the savings and the potential of that chip it might be advantageous to purchase a retail 1800+. Obviously NewEgg doesn't guarantee which chip you'll get so there is some risk, but I think it's likely you'll get the same (or a very similar) chip as I'm sure most of the older chips are no longer in stock.
Test 3200: If fail go to test 3000
Test 3000: If fail go to test 2500
Test 2500: Pass, sell as 2500.
Of course, those 3000s are still perfectly acceptable chips and might only need a slight boost in voltage to make it a 3200. The fact that it's a 3000 also means it was fabbed from closer to the center of the wafer, and therefore has purer silicon inside.
Also, I think quotas has some factor in marking. If AMD thinks it needs 20,000 CPUs badged as 3200+ for a 3-month period, then it probably only checks until it has 25,000 or so (for a bit of a buffer) and then starts on the 3000+ and gives a bit of a buffer and then moves on down the list. Is it not possible a 2500+ could be a chip that was never even checked to run at 3200+ but is perfectly capable of running at that speed or better?
/me thinks that thrax just didn't wanna type all the possible proc's out ;)
Not true at all.
I know several peeps that has either the 3000 or 3200 and they perform MUCH better than a good 2500. On default voltage, the difference is even greater.
Methinks you're right, as is Mackanz.
Unless I was drunk and I don't drink alcohol btw, I don't recall talking about Barton's 2600+ ever anywhere...
Sorry, as I thought it was you that mentioned these about 2 weeks ago.
Cheers!
Also how does the whole fsb setting work when comparing the cpu fsb and the memory speed etc. I've heard you can get into timing issues if you try to use 400 ddr ram with a cpu that has a 333 fsb which is why i stuck with the 333 ram in the first place. Does changing the fsb setting in my motherboard's bios change the cpu fsb as well? I kinda confused as to how all that stuff works.
That would be the minimum and PC3500 would be even better.
It is not an issue to use memory rated to a higher speed than the CPU but is a very big issue to run your memory at a faster speed than your CPU. You always want to run syncronus, meaning the same speed for memory and CPU. This is why I always tell people to get at least PC3200 memory when buying any CPU and an NF2 board.

There is now a 2600 Barton with the 512 cache as well as a 2600 T'Bred with a 256 cache. If you go to Newegg, you will need to choose "ALL" under AMD XP to find it.
