Altix 350 memory issues - Donjon - 10-20-2020

Hope this is the right place.

I'm trying to upgrade my Altix 350 to the maximum of 24GB per node (12GB per CPU), unfortunately, I'm getting memory errors during the memory self test. The machine works fine with the mix of 1GB and 512MB PC2700R modules it came with, however I've tried a couple of sets of 2GB modules and neither work. Firstly, I tried some Samsung PC3200R and secondly Micron PC2700R.

I feel like I'm missing something obvious, but I'm at a loss as to what!

I've had to edit to include the log of the failed boot (with Micron modules) as the forum seemed to think it contained contact details.

Altix systems go in Itanium. It's not MIPS.

RE: Altix 350 memory issues - lunatic - 10-20-2020

I found that my 350 won't accept any generic memory, even though it matches the specs of the original memory. I cross-checked these modules in HP Itanium machines and they worked fine. The Altix just wouldn't accept it.

Thanks to Raion for moving it; I'd completely missed this forum.

Thanks, I wonder what the issue is. Maybe it's expecting something very specific in the SPD eeproms.

I'm sure the memory will find its way into something; quite possibly my HP Itanium will be a beneficary
