AMD XP on A7V133

Well...u have the absolute latest bios right???

and r u positive ur 1.333 was a 1,333 and not a 1,300MHz ??? (one being 100Mhz FSB the other being 133Mhz FSB) cuz maybe im suspecting ur ram doesnt like running at 133MHz.....if this is the case...how'd u manage to update ur bios to the latest if u Crushed/cracked the core on ur 1.3 T-Bird ??

I'm sure i have the latest bios, because that's the only reason i could use an XP in the first place. (I borrowed someone else's proc to do the bios upgrade. :-)
And yes, i'm sure about the 133MHz FSB on both procs, too. I made sure to double check that because my dram is 133MHz.

Sure is a 1.05... one of the first things i checked when doing the bios upgrade.

I replaced my 1333 T-bird on the same Asus A7V133 with Onboard raid controller. With an Athlon XP 1800+ my board came with the 1.007 bios which worked with XP's. But windows XP was unstable on my system after switching the processors and doing a Full format and reinstall. I updated my bios to 1.009 so see if it your cure my XP problems didn't. So now I went back to win2k and my system is rock solid.

Kept getting BSOD and memory dumps with WinXP with the XP processor. And it wasn't happening with my T-bird. I believe that this asus board is still the issue but until I upgrade my motherboard I'm gonna stick with win2k. I also tried different memory modules in my board with no cure for Win XP.

Also on a side note I know the A7V133 works with Athlon XP's but I don't think it will with a XP2100 I think its XP1800+ and under.

I'm aware of that but some older KT133A chipsets have a limit to how fast an Athlon XP u can put in them.
My prior MSI K7T Turbo would only take up to an Athlon XP 1800

They had another version MSI K7T Turbo 2 which would take higher speed XP's.

I'm not sure if asus is doing the same thing but its possible!

Mak, my gut tells me i think you may be right about the KT133A chipset speed limit. I may end up having to bite the bullet and get a new mobo. :-(

MR, here's a summary of the complete specs: ASUS A7V133 rev 1.05, Award bios v1.009, KT133A northbr, 2 x 256MB PC133 SDRAM, bios set to run cpu at 1300 MHz (13.0 x 100MHz FSB) DRAM at 133MHz, CPU core voltage manually set to spec at 1.75V because bios was auto-setting it at 1.60V. Oh, and a 300W power supply.

WinMe installs and runs perfectly with this config, no complaints at all. As soon as i jack proc speed up to rated max 1733, it kaks.
Win2k refuses to install no matter what the bios config.
This doesn't sound like a power supply *or* DRAM issue to me...

The strangest thing about Win2k is that it behaves as if the cd was defective - it stops during copying on the exact same files every time. A friend of mine tried to use the same cd to install on his machine, and it worked perfectly.
Go figger.

Yeh, muking around with the CPU and FSB multiplier is what i did most... Win2k doesn't seem to care at all what they're set to, it refuses to get past copying those certain files. I tried skipping those files, but of course that made the final result flakier than Kellogg's on a Saturday morning.
WinMe seems to care only that the CPU speed is 1300. No, i haven't unlocked it yet... too busy with school now. Considering what i've tried so far, i doubt that unlocking the cpu will produce any different results, but i am more than willing to be surprised. Just as soon as i can find the time... :-)

VIA never officially supported the XP processor on the KT133a chipset and mobo makers did modified some of their mobo's to make it work, some more successful then others. Still over all I believe that it isn't a very good combination. My KK266 and a XP1600 would boot and even run 3dMark2001 but overall very unstable.
