  • MSI 745 Ultra and Barton 2500+

    Does anyone know for a fact if this would be compatible? The latest BIOS says it adds support for the 2400+ and 2600+, both Thoroughbred cores. The 2600+ is a 333mhz bus, as is the Barton 2500+. So, before I jump and upgrade to one of these, I'm wondering, 'will it work?'

    The 2600+ it's talking about is a specific CPU; the 2600+ with a 266mhz FSB, which is why mine is listed as a 2600+/266. This CPU is a bit hard to find, but gives a bit of a tweak to older boards like my 745 Ultra.

    The other AthlonXP's from 2500+ and up have a 333mhz FSB, which AFAIK you can't use with the 745 Ultra.

    If you're building a new system I'd opt for one of the newer SiS 748 boards that not only can support a 333mhz FSB but also a 400 mhz FSB for the next-gen AthlonXP's.

      hm......
      The MSI 745 Ultra can run at 166mhz (Greebe is rumored to have run his at 183mhz ) so technically there is not impossible.
      Althou the BIOS will probably missidentify the CPU it should run.
      Unfortunatley I have read no "evidence" of this working
      But when the Bartons goes down in price to where I can afford it its Likely I'll test it myself

      Worst thing that can happen:
      1. won't boot at all: Stupid BIOS
      2. Won't be stable at 166: you'll end up with a Barton 1700+ (running at 133fsb )
      If there's artificial intelligence, there's bound to be some artificial stupidity.

        Agreed on all counts. I wasn't trying to encourage overclocking though as it's banned in my lab for obvious reasons.

          I have actually read accounts of it working (I'll have to look for those links) and decided, a few weeks ago, to give it a whirl. All I have left is to mount my drives in the case. I should have some more info before the week is done.

            I think its irritating that SIS didn't say that it was OK or that MSI made a "overclockers" BIOS to it (they have done so in the past)

            It reminds me of the BX and 133fsb
            and in this case we don't even have to worry about pci abnd agp out of range becase it has the divider neccesary to make it work

              So, it might work and it might not, I think thats a no go for me then. I'll just see if I can find a 266/2600+ and failing that get a 2400+. I'm just upgrading btw, or considering upgrading anyway. The 745 Ultra is what I have now with a 1600+ in it.
              Anyway, thanks guys, I have the answer that I wanted (well, actually I would have preferred a positive answer, but I'll take an answer either way I won't waste money on a cpu that only 'might' work).

                I'm going to get a 2400+
                I've got a 1800+ now
                The 2600/266 is hard as hell to find
                If there's artificial intelligence, there's bound to be some artificial stupidity.

                  Funny you mention the 2600+/266. I just had a hard time with a computer I was installing for a friend. I had bought a boxed XP2600+/333 which wouldn't work with an Asus A7N8X-Deluxe mainboard (the board wouldn't even reboot after I set the FSB to 166). It turned out the chip wouldn't support 166MHz FSB because it had a 16.0 multiplier (do the math). I had to set it to 133 MHz and it happily ran as 2600+. The goodie part is that I could choose about any multiplier (dunno if it was a feature of the Asus board or the chip being unlocked) so it now happily runs as a 2700+ (not a big OC but anything free is pleasing ). It came from an official AMD distributor BTW.

                    Pretty much all of the new boards unlock TBreds.
