T-Bird 1.4G to T-Bred 2400+ causes WinXP hang

Hi guys,

Bit of a follow up to my other post. I replaced the 1.4Ghz T-Bird on my Epox 8k7a+ with a 2400+ XP.

The mobo detects and identifies the processor correctly as a 2400+ XP. My temperatures are fine - ~42 C. There are no error messages in the BIOS load or anything like that.

Windows XP, however, simply will not boot. In normal boot it will take me to the logon screen, where it will simply hang and will not respond to the mouse or the keyboard. No error messages or BSOD, it just stops responding. In safe mode, it typically hangs when trying to load amdagp.sys (or something close to that). Even booting from the XP CD and trying to "repair" the windows installation just causes the system to hang.

Ideas?

underclock the CPU...the mobo could be givin the CPU bad voltage. Underclocking means the CPU can handle less volts.

Obviously this is a quick fix if it does work

can you fresh install windows? try that and see if it works.

uhm...i suppose you may have gotten a bad chip too. maybe try it in someone else's board to see if it works properly.

I've got a book of matches,
I've got a can of kerosene,
I've got some bright ideas involving you and me.

I tried bumping both Vcore and Vmem to no avail.

I did a clean format/install

I can't underclock the chip on the 8k7a+ w/o unlocking it, and I don't want to do that.

I was unable to be stable even long enough to install XP. Upon doing more research, I find from others with the 8k7a+ and the 2400+ that it is a bit difficult to run stably, as the board's voltage regulators are not designed for T-bred core (this was from a post from an Ep0x tech support).

While others have successfully gotten it to work, it seems a bit beyond my skill level with mobo tweaking. I wish I had done a bit more research before I bought. Looks like it's back to the T-Bird.

Go go RMA!
