Athlon T-Bird Overclocking

[Guest]

I recently fried my 1.1 ghz Athlon, and was reduced to save money to buy a 1.0, So I figured, get a better heatsink/fan and OC the thing. I clocked it up to 1.1, and it's running pretty smooth, no unexpected system crashes or anything. In fear of really damaging my chip, I was going to clock it up to 1.333, Does anyone know if this will be ok? I got a Dragon orb 3 7000 rpm fan on it now, and it is running at 113C, Alot cooler than my 1.1 ran at 129.5 with my crap ass super cooler.

What the hell is a gigaflop, who cares it blows away Pentium

I think that going from 1.0 to 1.2 should be fine but I'm not sure about 1.333. You've got to be carefull and get monitor program for windows so you can make sure that your not burning up your CPU. your temp should never go more than 50 (c).

If your temp was even NEAR 113C your comp wouldn't be running, that is 113F not C, you should be ok up until about 130F...Might be a bit higher but hopefully a more knowledgable person will answer....

Do you recall if your core is an AYHJAR-Y, AYHJA-Y, or an AXIA core? They are all good steppings for overclocking.

I've got my Tbird 1.0 (AYHJAR-Y) overclocked to 1.5 at 1.87 volts. It runs temps from 41 to 49 degrees C (106 to 120 F).

OK, that's not quite true. Most of the time the Tbird is at 1.33 ghz (to keeps temps between 38 and 46) but when I play games I use SoftFSB and crank the FSB speed from 133 mhz to 150.

I'm using a $4.50 Heatsink but I added a Delta fan to it. It's a <A HREF="http://www.nexfan.com/29/248.htm?463" target="_new">Galaxy GC21</A> available at <A HREF="http://www.nexfan.com" target="_new">http://www.nexfan.com</A>

Check out the CPU Database at <A HREF="http://www.overclockers.com" target="_new">http://www.overclockers.com</A>. The average overclock for a TBird 1000 is 1344 mhz.

i never got soft fsb to work...
i even checked my clock generator and chip, it just locked up as soon as i touched anything. most depressing
kt133a chipset

The lack of thermal protection on Athlon's is cunning way to stop morons from using AMD.

Do you have the correct .pll file for SoftFSB? I guess you must if you can select your clock generator. I use a file called "ka7pll205-01step.pll" which has worked for both my Abit KT7 and my Epox 8KTA3PRO (KT133 and KT133A chipsets). I believe the same clock generator is used with all KX133, KT133, KT133a, and early KT266 chipsets.

Do you have trouble raising FSB via BIOS as well, or just using SoftFSB?

Have you tried raising the core and I/O voltages? I keep mine high enough to run stably at 1500mhz (150*10) even though I'm normally running at 1333mhz (133*10). This way I can bump the FSB anytime I want and know I won't have any problems.

honestly i dont know...
the correct clock generator was in the list, and i checked it to the on printed on the chip.. bit if i tried to twiddle anything after selecting it it froze solid.

moot point anyway, found out that FSB overclocking is BAD for me...
evil combination of increased FSB + IDE controller + old IDE drive = perminantly fried ide controller.

so this board is now dead, but still useable for 95% of things fortunately.
thus my search for a 166fsb/166DDR/33pci type board
im plannin a big upgrade!
