Re: [suse-amd64] meminfo Tyan 2880/6GB
Mike & et.al., I wish the toy was mine. The RAM all came at one time from the same vendor and is matched. I have tried moving them around to different slots with no change. :) It is sad to have such a nice toy not living up to its potential. The historical story is: We bought the RAM, MB, and Processors from the same vendor. Lodaed up SUSE and let the machine run. It ran without problem for about 2 weeks with all 6GB of RAM. Then the UPS it was plugged into failed and the machine went down. The board would never boot again with more than 4GB. The board a couple days later died completely. We RMAed that board and had to order another (since it took them 2 and a half months to get us the replacement board). The board we orderded (same model) is the one in the machine now. The RAM is the original RAM, as are the processors. Mike Rosing wrote:

Since installing memory about 4GB I have to boot with iommu=force. Also, the machine hung after being up for two days without any error (that I have been able to find so far). The BIOS version is 2.02 (latest).
Any ideas on what is happening with the memory and how I can fix/take care of the reporting error? I think that it may be related to the hang as the machine was stable for 6mths+ with 4GB of RAM.
Santiago,
You are definitly pushing the limits of technology! My bet is the new ram is either getting too hot or is not the same speed as your original ram. Try adding fans and moving the ram chips around to different slots. I'm not sure what will work - I'm just jelous you've got such a nice toy!! Good luck - I suspect it's not a trivial problem. But it might be easy to fix.
Patience, persistence, truth, Dr. mike

Ouch! Sounds like one or 2 of the ram cards got wrecked along with the motherboard by the power failure. But I suspect they all work when you only have 4 in the machine, it doesn't matter which ones got wrecked. At these speeds and densities, it does not take much to make things unstable. I'd check to see if the motherboard or ram manufacturers have some kind of diagnostics you can run to check the ram. If you are lucky, they will tell you which ram card is faulty.

I would try updating the kernel. I have a S2885 that I spent months
getting graphics working on. As part of that effort, there was a patch to
the mtrr.c part of the kernel that picks up information from the BIOS.
There were a couple of 32 bit pointers left there that should have been 64
bit. This caused instability that did not show up until you had more than
4 GB (the 32 bit max) of physical memory.....
