Mmm, I purchased a TBird 1.333 a week ago, and I am running it on my KT7A motherboard(also recently purchased). I had several problems during installation, Windows Xp was being a bitch (eventually I had to give up on it and go to Windows 98), then I had various hardware conflicts etc. etc. etc. And my computer seemed to enjoy crashing. I don't think the Cpu Fan ever passed 60 degrees C. So then, I decided to clock down my cpu to 1.2. Still crashes, however ever since I've clocked it down to 1ghz it's been fine. No crashes. On my initial boot up the cpu read as a 1ghz chip. I bought a retail cpu(not OEM). I'm just curious, is this actually a 1ghz chip? Or, is the Abit Kt7a unable to detect speeds higher than 1.33? If I want to up the speed in the softmenu to 1.33, should I use the default multiplier given in the menu? change it to my own?
35 Celcious right now? thats very good.
Try takign your CPU out of the Motherboard and check the amrkings on the DIE, see if it is actually an authentic 1.333GHz CPU, and not a 1GHz part.
it should read on the first line of the core (besides AMD Athlon)
If it doesnt than you dotn have a 1.333GHz CPU, but instead a 1GHz part that the L1 bridges were not cut on....

I've got my 1200 stable @133x10 also with the abit kt7a.
Still...I see people are having problems so I wonder about the boards. I can post, boot, and even play, at 1400 but I get lock-ups every hour or two (could be my ram though).
You didn't mention whether you're running 133fsb or 100fsb
or what ram you're using. If you're running 133fsb then you need a good, or least decent, ram...and for sure rated for 133
Also the CPU could actaully be, "B", rated for 100fsb, In which case it will probably never be stable at 133fsb.
Besides RAM and FSB, the PSU (power supply) could be inadequate. You simply must have a good 300w or better PSU.
You must maintain a 3.3V for the I/O
Vcore should be steady 1.75v min (although ppl say they can go lower), I find maxing it out 1.85-1.825 gives me more stability.
60C is "kinda" hot...within spec...but kinda hot...is that idle temp or max load temp? You could need better cooling from your HSF.
And finally, the CPU drive strength should be 3. Other ppl may say different, but it did wonders for my OC stability.
...Hope that helps
