Proliant 3000/5500 Xeon CPU Upgrades

[David Fitzgerald_1]

I understand that the PL5500 has switch settings that would allow one to run the Pentium III Xeon at speeds up to 600 MHz. I've read the doc on mixing processors speeds/caches/steppings but have a question.

As 600 MHz chips only seem to come with a L2 cache of 256K, could I use say 700MHz chips with a 2MB L2 cache, even if I set the speed to 600MHz? Will the chips slow themsleves down to 600MHz? I intend to use 4 such chips.

As I currently have CPUs running @ 500MHz with L2 cache of 512K, would running 500MHz chips with 1M or 2M L2 cache be worthwhile? Used chips seem cheap and available.

If you would install 3 additional 500/512K and two 512/1-2M it would work, and you would benefit in speed. Better even install 4 of them with bigger cache. Since you mention that you have a doc on processor mixing/stepping info check thew rules for processor cache mixing...
