I have a Dell Precision 220 with 256 megs of RDRAM. Non-ECC. The 220 is in a desktop case with a 230 watt power supply. The system has a LSI-Logic dual channel SCSI host adapter with an ultra-160 SCSI 10K RPM drive. The graphics card is a Matrox dual head G450.
Two 866 Mhz PIII's (retail boxed processors) with the same stepping.
Does Dell really sell this with 2 cpus and only the 230 watt supply?
Yes they do. Hard to believe isn't it?
I'd have thought something much beefier would be needed. You can either try w2k or xp, or just get a 400 watt ps and see if the problem goes away. Of course that will void the warranty, but your mention of "retail boxed" on the processors makes one suspect that you've done that already.
These machines did work just fine when they were running w2k. (I bought the system from work at a great price. There is a tower version of the system. But Dell no longer makes these systems)
To digress I would not mind finding a bigger power supply but that is the problem; I don't know if such an animal exists. This system can take two disk drives, two sticks of RDRAM in addition to the two processors.
I am thinking of just chucking the Dell case and purchasing a real case with a hefty power supply. I have not really looked into this. For all I know this might not be possible. I know from looking at the system that the main cooling fan uses a non-standard fan connector that plugs into the motherboard. (Great way to guarantee you buy the replacement from Dell) I will have to check the motherboard power supply connectors as well as the mounting holes to see if it is possible to use an off the shelf case.
I am thinking of installing another Unix system and running the same test.
I also noticed that the FreeBSD SMP code is said to be non-production code. If this is the case it will present a problem since this is the system that is going to be my primary server and also serve as the server for my wife's business.
Does anyone know if the FreeBSD 5.0 SMP is an improvement over what is in 4.7? If so I would not mind downloading the latest snapshot and trying it for a test.
Thanks and happy holidays, Marc
