- If your 3000 has a Ramsey -04 and SDMAC -02 (used in almost all production),
- you may indeed have a temperature problem. These chips would only talk to
- each other over a rather limited temperature range above ambient. Placing an
- accelerator card over the Ramsey causes many 3000's to crash in some manner
- after power up for more than 10-15 minutes. Especially if the cabinet is
- closed and there are several hot- running cards on the expansion side.
-
- Replacing the chips with Ramsey -07 and SDMAC -04 usually fixes the problem.
- A blower forcing air between the MB and accelerator may also do it. Then
- again, you may just be overloading the 3000. If, after 1-2 hours, parts of
- it are too hot to keep your hand on (hard drive or bottom plate under the
- right side especially), you should consider increasing air flow or removing
- some stuff. Your 3000 might work for awhile with new chips, but this much
- heat will likely cause early failure of components and/or drives. The back
- corner is a particularly poor place for a high RPM drive, since there is no
- air flow, and 5400-7200 RPM drives get a lot hotter than the old 3600's.
-
- Try this: leave your cabinet top off, and direct a fan into the guts. If
- your problem never appears.........
