Montecito

Jens Kieffer-Olsen — Wed, 28 Feb 2007 10:34:24 GMT

Our rx4640 has 4 processors 0x000000001f020204
so is their official name Montecito?
Or are they only designated Montecito, if we upgrade to dual-core?
Point is that Oracle states "The Montecito chip is certified on patch set 10.1.0.5 and higher".

Well, first, an rx4640 is not a workstation :)

Second, if you have all four sockets filled, and only four cores showing, unless two of the sockets were disabled with the EFI cpuconfig command, you likely have "Madison" processors.

If you are running HP-UX I suspect that machinfo may give some clues. If running Linux then I think you would cat /proc/cpuinfo

Neither Montecito, nor Madison are "official" names, they were just codenames. Official names are much more dry.

In broad handwaving terms, dual-cores are Montecito (well, there was mx2...) however, there is also a single-core Montecito.

Hi,

do I have a montecito dual core cpu or not?

How to identify?

Thanks to Rick and Torsten. I managed to find an article that indicates a Montecito shows family number 32. My processors have an L3 cache of 6M just like the 9010 mono-core Montecito, but since the family number is 31, I conclude that the processors are of type Madison 9M model 2 revision id 2.
So, no cigar to the rx4640 :-)

Although, if you want you _can_ upgrade an rx4640 to Montecito processors. Better still would be an upgrade from an rx4640 to an rx6600 :) Or an rx3600 if you only really need four cores (two sockets).

ok, but as it happens we have an option to upgrade the rx4640. The confusion owed to the fact that we thought we had single-core Montecito processors when in fact we had Madison 9Ms. Point here was that Oracle indicates our current 10.1.0.4 version isn't certified for Montecito, which would not make sense, if our processors were already Montecitos. - Now we will upgrade to 10.1.0.5 and then bring our upgrade option into play.
