Re: 875MHz proc on rp7400
http://www.hp.com/products1/servers/rackoptimized/rp7400/specifications/index.html
Specs for rp7405:
http://www.hp.com/products1/servers/rackoptimized/05series/rp7405/specs.html
Specs for rp7410:
http://www.hp.com/products1/servers/rackoptimized/rp7410/specifications.html
The rp7410 is the only one of those 3 that lists the 875 MHz processors.

Re: 875MHz proc on rp7400
Another type of system board needs to be made by HP to support PA-8700+ CPUs, making them a total of 4. :-)
HTH,
Vince

SolutionSince then it has had the memory bus frequency upped to the max of 133 MHz, and has seen three additional CPU frequencies - 550, 650, and 750 MHz. (Ie a total of five CPU frequencies in that box, over a range of 2X, which is about all one can reaonably expect)
While I suppose there are some workloads where the now 5-ish year old memory bus could support 8, 875 MHz CPUs doing useful work, the number of such things is likely rather smaller than it was for 750, 650 and 550 MHz.
Now, the rp7405 and rp7410 have a new and improved memory bus and are much better able to support 8, 875 MHz CPUs doing useful work. Hence, they have support for the 875's and the rp7400 does not.
The rp5470 has the same memory bus as the rp7400, but only supports up to four CPUs, and it is much more plausible for that memory bus to support 4, 875 MHz CPUs. So, 875 MHz CPUs are supported the rp5470.

Re: 875MHz proc on rp7400
If your running 11.0 you can only go to 750s. The 650s & 750s are PA-8700
chips. When the 875 came out it is been a PA-8700+ chip. This whole +
thing on the end has never been done at HP. Basically, the 8800 isn't
ready and they didn't change anything FUNCTIONALY on the 8700. But they
did change some of the physical construction of the 8700 to make is run
faster. I believe the 11i OS got a patch to deal with this "inbetween"
generation chip. But for 11.0 HP isn't doing anything. So 750s it is.
