Superdome CPU upgrade path

I'm running some SD-64s with 552 MHz CPUs (PA-8500s?).
What's the upgrade path? Can I go 8700 (750 MHz)or 8700+ (875 MHz) on the same chassis, or what are the issues here?

Re: Superdome CPU upgrade path

I think the chassis is fine, but to get the faster 875's you need a mainboard upgrade/replacement, which is a big job. Its not just a straightforward cpu replacement. These boards hold a few cpu's each so if you upgrade you will have to upgrade 4, or more, cpu's to the new spec at a time.

Re: Superdome CPU upgrade path

You can go all the way up to PA8800's (dual core) which will hopefully be released sometime Q2-2004. You will most certainly be upgradig your mainboards as well.

BTW, anyone know for certain if the PA-8800 CPU's (dual PA8700's) will finally be available in April/May?

You need to change the cell board for that partition at least, means purchase new cell board.

BTW you need also to upgrade the Firmware.

Re: Superdome CPU upgrade path

Thanks, guys.

I sort of assumed that a CPU board replacement would be the case, but wasn't sure if there had been changes in the cells.

T.M.Louah has given me that answer for the 8800s.
