Tbird unlock

[xbassman]

I am thinking about unlocking my 1Gig TBird. It has been running fine @ 1.2 locked (10-1) for about a year now, but soon I will be replacing it with an XP 2000+ and am curious to see how it would do running the bus @ 133mhz.

Have any of you tried the pencil trick? Does it last very long?

Few things, unlocking will not change the FSB, all XP CPUs run at 133FSB stock, the pencil trick will not work with Athlon XP CPUs only with Duron and Thunerbirds. If you want more info on the XP mulitplier unlock details check out my Athlon XP unlocking kit review at my website OCModShop

I unlocked by Tbird 1.0 using the pencil trick. It is currently running at 1.3 (10.5 x 126) and has been running seti non stop for over two and a half months now. I would up the FSB more but it only has generic PC1600 DDR in there that wont do 133 FSB.

thanks menendo,

I have a couple of errands to do then I am gonna try it.
Right now my bus is @ 120. I have micron pc133 cas2 ram and it becomes a little unstable if I take it any higher (because of the pci or agp bus)

Anyway I am gonna drop it on a new mb. It should be here Monday. It is an Asus A7V266-E and Corsair PC2700 XMS ram so iI don't think memory will give me a bit of problems.

Kinda funny though...when I first dropped in this processor, I could boot and run for a short time @ 10 x 133, but I would crash after running a few apps. Now it won't even POST at that setting.

xbassman, have you tried raising the Vcore a few notches? it might help you post and boot to the OS.
What is your CPU stepping? Because you might be able to boot @1300+ with Vcore of 1.85 with some medium cooling.
If you want to unlock you CPU multiplier(the 1Ghz T-Bird) you should connect the L1 brdiges using a B5 mechanical pencil and when you're done see if it's working.If it works You may want to put some clear-sticky-tape on them in order to keep them that way.

Yes I have...and I can't post when I do this.
I can't remember, but I think I have to change a jumper. (I have an A7V133)
It has been a while since I toyed with it.

The A7V133 isn't such a good board for overclocking. I happen to have one myself too and I noticed a problem which might be similar to yours: It doesn't matter what cpu speed u overclock or even downclock as long as you set your VCORE via bios the system won't boot. It happend to me with the 1007 bios(the latest official bios), though when I overclocked my cpu and the vcore was set to AUTO the board automaticly upped my vcore to something aroung 1.80~ but. If I tried to boot at anything higher then 1500 I had to set the jumpers manually to 1.85. Might it be you problem too?
