How can I see I have an XP 3000+ 333 or 400FSB?

I just bought an Athlon XP 3000+, the bill said that it was a 333FSB version. But the standard 3000+ settings in the BIOS say 200MHz with 10.5 multiplier (so 400MHz I know). My RAM is only 333MHz FSB and my motherboard (NF7-S 2.0) can do 400MHz.

Now I have some questions:
- Is there a visible difference between a 333FSB 3000+ and a 400FSB one (like in the serial number) or any other way to determine the which one it is. I want to be sure.
- Can an XP 3000+ 400FSB run at 300MHz FSB?
- My RAM is 333MHz, can it run at 200MHz to work with the 400MHz FSB (I believe so) and does that work well?

Specs:
Athlon XP 3000+
Abit NF7-S rev 2.0
AwardBIOS
Kingston 512MB DDR333 RAM (below €100)

  1. look at the bottom of your CPU, there should be a number like "AXDA3000DKV4(D/E)"
    then last letter, D or E, tell whether your CPU is 333FSB or 400FSB, D=333, E=400
    and yes, a 400FSB cpu should be able to run at 333FSB
    and no, you can't run DDR333 to DDR400, that's way too high for a DDR333
  2. it's an E
  3. Who cares! Athlon XP chips are pretty much universal in nature where names dont mean much. Just pop it in there and see what you can get out of it. You can make the barton 2500 be a 3200 or the 3200 into a 2500. But thats just me

    Barton 2500+ @ 2200mhz (10x220 vcore @ 1.775)
    Asus A7N8X Dlx 440 FSB
    1gb Geil GD pc3500 Dual Channel (2-3-3-6)
    Segata 80gb SATA 8.5ms seek
    ATI Radeon 9800 Pro(420/700)
  4. Wow, then you are lucky, getting a 400FSB cpu instead of 333FSB
    just change ur memory to a DDR400, a better idea
  5. Lucky? Now he has to either spend more money (upgrade the memory) or suffer performance loss (asynchronous under-FSB memory speed).

  8. LOL!

    Maxtor disgraces the six characters that make Matrox.
  9. yeah, LOL.. :eek:
  10. Hey, it's an xp3000+. It's supposed to run at about 2.2 gigs, so make it so. Run your fsb as high as the ram will allow. If your multiplier is still unlocked, raise that to. Good luck.
  11. I've got cheapo 333 memory and barton 2500+. Got it running sweet as a nut 400mhz 3200+. Just lower the memory timings a bit it'll be sweet
  12. Shouldn't 3000+@200FSB be run at 2.1Ghz?
