Upgrading CPU on Alpha PC164SX w/533 mhz

Post by DiskMa » Sun, 22 Sep 2002 21:03:07



I was wondering, is it possible to update the 533mhz 21164 cpu to the more
advanced and seriously FASTER 600mhz 21264 unit? Even though it doesn't seem
much, the 600mhz will run about 3x faster... I've people talk about it but I
never heard of it being successfully done *grin*

It's impossible.  The socket is different to begin with.

ouch, I might have to snag another board or something. Ifound the cpu dirt
cheap and its about 7x faster than the 533 ....

How can that be?  The 21264 has out of order execution and probably
bigger caches, but it shouldn't make that big a difference.

check out Seti... the 533 does a work unit in 10hrs while the 600 does it in
1hr...

Bigger caches could be very helpful here.  The penalty for a cache
miss is rather high.  The CPU core isn't so different that it should
make such a big difference.

What version of Seti are you running?  Not 3.03 I would say.  My 833Mhz
21264's under REdHat average around 5 hours per work unit.
