dumb athlon cpu question. is there something physically different about the AYHJA stepping?

[flashbacck]

I was looking for a cheap athlon processor on newegg and I come across this:

AMD Athlon Thunderbird 1.33GHz 266MHz Bus Socket A PGA Processor -OEM Version Stepping AYHJA(Requires fan that supports 1.33GHz processor Stepping AYHJA)

none of the other athlon's mention anything about requiring a special cpu fan. Is there something different about the cpu in the AYHJA stepping?

thanks!

most likely not...

ive read that a couple times too, but never gave much regard to it...

afaik, there is nothing different
nothing like adding more layers and whatnot like they did to tbred a's to make tbred b's

I had one of those chips, AMD TBird 1.33GHz AYHJA. I used some random hsf until I wanted to o/c it then I got an Alpha MC462A with a big 80mm fan. It was fine with the generic hsf (some Taisol unit). And it overclocked well too.

cool! thnx for the replies!

Good thing about that CPU is that it comes unlocked, I'm running one now but I think my RAM is holding me back from anything above 136mhz FSB

If you have good RAM, I'm more inclined to think that your mobo is the culprit. With my KT7A-RAID (rev. 1.0), it gave me fits at anything over 133 FSB with the A9 BIOS, and that was with Mushkin rev. 2 PC 133. If you have a rev. 1.0-1.2 board, you might try flashing it with the rev 1.3 BIOS, 9R. I did that while trying to get a pally to work better and it let me get up to 145 FSB stable. I guess maybe there are some timing differences between the 2 versions.

not a dumb question!

AYHJA athlons were good overclockers. Quite a few of them were able to run at 1.5+Ghz. I had a 1.2Ghz@1.456Ghz for a long time but my original kt133 chipset held it back I think. I don't think there is any difference that would require a different fan other than one usually needed for overclocking.
