Hi Andrew,
Thank you for passing this info. On.
We will take a stop by Hayden today.
I will keep you posted.
Best,

That's odd; I've seen that message from hayden-7 as well, but continuing the boot attempt (with, I think, F1) worked OK for me.
The basic problem is that someone stole half of its memory, and slot #1 is now empty, and having memory only in slot 2 is indeed not a supported config. (It still worked, though.) It should presumably get a new 2GB DIMM in slot 1, but you could also just move the DIMM from slot 2 to slot
1 and you'll stop getting the error message, but the machine will have half the memory it should have.
Note also that hayden-6 and hayden-8 were also messed up when I looked at them a while back, and (since all three are reporting only 2GB) I think they still are. See below for a bit more background...

Subject: likely RAM theft from three Hayden cluster machines
Hi, all. In the process of checking out the install problems on hayden-5, I noticed that hayden-6, hayden-7, and hayden-8 are all missing some of their RAM.
In particular, -6 has had both original 2GB DIMMS removed, and -7 and -8 have each had the easier-to-remove DIMM removed. Hayden-6 still boots beacuse it has a pair of 1GB DIMMs installed instead.
My theory is that somebody with a 2GB machine stole 8GB from the cluster machines and left behind their original 2GB.
Note that none of these machines have AnchorPads or are otherwise locked down.
If my theory about what happened is correct, there's at least some chance that the two 1GB DIMMS in -6 are traceable to their original owner.
fyi,
andrew
