  1. Your current fsb is 100, with a multiplier of 8. You need to change these. To start with, ibelieve you have to go into the bios and enable top performance. Then you should be able to change the settings in advanced. Maybe start out slow, like fsb of 200 and multiplier of 11.
  2. Off hand can't remember that bios too much. There is a jumper on the mobo for cpu clock. One position is 100MHz for the durons and old 200 bus TBirds. The other is auto I believ and is for 266 and 333 bus chips. Make sure this is on Auto as it should have been anyway for your XP2000+.

    There are also jumpers in a block that can be used to set the multiplier manually if you have issues in the bios. I think they go up to 18 or higher.

    I am drawing a blank on the bios now an can't hook mine up right now to check, but if you don't see options in the bios to set the fsb or cpu host frequency and the multiplier, hit CTRL F1 to bring up the advanced chipset features. I wouldn't start higher than a 166 fsb on that mobo and work the multiplier up. Turn off the top performance as that will stress your ram. Later you can try turning that on once you find your max OC. I think that mobo can reach a 200 frequency setting, but I wouldn't wager it will do that. Start 166 and 11 or 12 multiplier and hopefully you can bump the multiplier up a setp at a time to 14 or even 15. Anyway, that's a start for you. if you have more problems let us know. if noone else can help, I'll set up my GA-7vax again and try it out. Lack of desk space has prevented it for a while. I was hoping to pop a mobile on that myself for a quiet 2.0GHz system soon anyway.

  3. I'm afraid that old mobo can't support this cpu offically,and i think you can not get what you want from this mobo(it must be using KT266A chip,so not easy to accept new cpu).Better upgrade mobo.

    Truth is somewhere out there!

  4. there are no settings for the multiplyer in the bios settings.
    iv had a look in the manual and the jumpers for the multiplyer go upto 12.5 and the other set of jumpers alow me to set them at 100 133 166

    the first set is on auto
    and the other is on 133
  5. I believe you have to hit control + f1 to get to the advanced setting. You should have access to the multipliers and fsb in thier. What revision is your board?
  6. its rev 1.1 when i press ctrl f1 i get extre settings but they are mostly for graphics eg fast write, agp etc
    would it make a differance if i changed the jumpers from 133 to 166
  7. Your best bet then would be to load easy tune 4 from your mobo setup cd. This is a prog that allows you to oc in windows.
  8. ok iv changed the jumpers to 166 and multi to 12.5
    and now my cpu is running at 2087.50
    however some strange things are happening like aplications are not shuting down properly this was also happening before at the lower frequency
  9. Google for memtest86, then put it onto a floppy to run it.
  10. iv put it onto floppy how do i run it?
  11. did you turn off top performance and adjust your memory timing less aggressively? Your ram might be fussing.


    start with optimal setting and find your highest 166 bus OC, then adjust the mem timing as aggressively as you can.

  12. It's a KT400, his mobo is fine.

  13. could the problem be that im using pc2100?
  14. WHAT! Oh my, yes... sure it is. :redface:

    If that was listed above, my fault for missing it. PC2100 is 266 DDR and you are trying a 333 fsb. Surprised it even booted into windows to be honest.

    You have to either try a huge multiplier on a 133 bus, or run the memory async with the fsb. otherwise you need PC2700 or faster to OC the fsb to 166 or higher.

  15. 512MB PC2100, pretty hard to miss. :tongue:

    Are you sure 12.5 multiplier is the highest jumper setting and it can't be changed in the bios? I'll look into it later today. If so, new ram or running async are your only options if you want to get more than 1.66GHZ. Ugh

    In the mean time, try 12.5*133 and see if it's completely stable.

  16. ok iv changed it back to 133 and 12.5 on the jumpers
    but im still having the same problem. i open a program eg easytune4 and then i cant change anything as the mouse moves but i cant click on anything and i cant shut it down
    but the keyboard still works
    after i ctrl atl del it it starts working again for a while
    this happens with other applications as well
  17. What bios version are you running. Gigabytes with the dual bios are easy to flash, but I'd pop in the XP2000+ and get it stable before flashing. Let me know the version. You need F10 or newer to support bartons (which this is)

    If you have F10 or F12 already:
    Besides the jumpers, what changes have you made in the bios? Specifically memory wise.

    What cpu voltage is it set at? Did it default to 1.45 or 1.5v. Try 1.6 or 1.65v

  18. Hi Paul.
    It seems she had this problem before, with her old proc. I have had the same problem, and found that the mem failed test 6 in memtest86. AFAIK the only fix is to replace the memory. It could also be a bad windows install, but memtest is quick, and always a good idea.
  19. To run memtest, first you have to allow the exe file to load the prog onto a floppy. Then just tell windows to restart. This does require that the floppy is still in, and that floppy is first boot device.
  20. Ah, I assumed no isues prior to the mobile chip Thx.

  21. Do you only have a problem with the mouse?
    what os are you using, and service packs?
    Is this a usb mouse?
    Have you checked to see if there are any problems in device manager?
  22. im using win2000pro
    its not a usb mouse
    iv put the xp2000 back in and it works fine now very stable.
    how likely is it that its my ram as if it is what ram should I get?
  23. Memtest86 will tell you if it is not a ram problem. If it passes tests 1,2,3,4 and 6 no problem, it is not a ram problem.
    What hsf are you using on the xp-m chip?
  24. im using a vantec airflow2 hsf
  25. That's a good hsf. Have you tried memtest?
  26. i cant seem to get memtest to work.
    i downloaded it to floppy the rebooted with floppy as first boot devise and it just sayes something like error on disk.
  27. Make a new file on your hdd, and copy it to that. When you exicute it, designate the drive to load as A:\ . It will then put an auto exacute on your floppy, that when rebooted will run memtest.
  28. ok iv done that, how long does it run for roughly and how do i know what the problem is?
  29. iv managed to borrow a 512 stick of pc2700
    im now running at 1900mhz 11/166 173 fsb
    and my temp is at 61 C
    does this sound about right. the system seems stable
    i tryed at 12.5/166 but the temp went upto 68 C is this to hot?
    and would i benafit from getting pc 3200?
  30. Let it run for a few hours to be fairly certain, it will report errors on the screen, can't miss it.

  31. Yes, in fact you *should* have PC2700 with a Barton 2500+. I don't think (m)any AXP motherboards can their memory slower than their fsb, so you need 166 Mhz capable RAM.

    Your temps also seem very high to me, is that just iddeling or running something like prime ? You have a decent HSF, I think you may not have mounted it properly.

    = The views stated herein are my personal views, and not necessarily the views of my wife. =
  32. it idles at 60
    would it be worth me getting pc3200? it seems to perform slower than it did with my xp2000 and pc2100
  33. >it idles at 60

    Thats too high, unless your bios is reporting bogus temps. Reseat the heatsink, reapply thermal grease, or let someone else do it for you if you're not comfortable with doing it yourselve.

    >would it be worth me getting pc3200?

    PC3200 is about the same price as PC2700, so there is not much point in getting the slower memory if you have to buy new one. But, there won't be a big, if any difference between them performance wise with your current cpu. The advantage of PC3200 is that you will probably be able to reuse the next time you upgrade.

    >it seems to perform slower than it did with my xp2000 and >pc2100

    Impossible really. Not running at the speeds your cpu and (future ?) memory is specced at (166 fsb, 11x multiplier). Of course, if your running your Barton at a 133 FSB because of the PC2100 memory, it could be slower than than the XP2000+. Not that a 2000+ ->2500+ is a huge upgrade either, but it definately wouldnt be slower.

    = The views stated herein are my personal views, and not necessarily the views of my wife. =
  34. ok iv pulled the hsf off cleaned it reaplied grease
    now my temp is idle 27 c and i played farcry for 20 mins and it went up to 29 c sounds a little bit better LOL.
    ok my settings are at 166/12.5 thats as high as my mobo will let me go. so should i up the fsb or what would be better?
    how should i test my jig to make sure its stable?
  35. sorry i meant rig LOL
  36. Easytune 4 should give you options on increasing the multiplier.
    The prog I like for to use for checking stability is prime95, esp cause it's free. The sysoft sandra burn-in is good as well. I like to run mbm5 at the same time, just to keep an eye on temps.
  37. 12.5 is the highest easy tune will let me go.
    so whats the next step. iv got to give this pc2700 back soon so im going to have to get my own im thinking of getting pc3200, will that alow me to increas the fsb
    and will it run ok with a mobile xp2500 barton?
