SGI: Hardware

The first generation of Octane has the complete model number in the sticker: CMNB015ANG300 or CMNB015ANF300. I know that CMNB015 means Octane/Octane2. The last numbers are the speed of the CPU and ANG/ANF depends of if It is single or dual CPU.

Can you tell me what of the letters (G or F) describes a single or dual CPU system?

Thanks!

Have you already had a look at the Octane-related info in the SGI Model Number Wiki ?

Ok, thanks.I was looking only the Octane wiki page.

Then there is no way of knowing if it's a dual cpu system or not outside hinv.

You can open the machine to see the processor(s) and their heat sink.

Yes, obviously. But I only have some pictures of the machine and there is nobody at the workshop to open it. BTW it's only curiosity.

The only way to tell would be if the CPU has been upgraded and the CPU part number sticker has been affixed in the proper spot on the name plate. Still, there is no way to say if the CPU has been upgraded or downgraded since then.

Yes, and this time this is a big problem. This machine seems an Octane upgraded to Octane 2 with cromed handles and Odyssey graphics... No upgraded CPU sticker but motherboard seems to be exchanged.

Don't rely on model numbers, I've come across soooo many systems over the years which have setups that don't
correlate to the internal hardware. Best way to be sure is either "hinv -vm" from within a running IRIX login (hinv
in Command Monitor isn't that detailed), or in Command Monitor enter, "system". Or failing these, remove the
boards for inspection (the owners guide on techpubs has info on extraction procedures).
