- I am having trouble with my CV64 S/N 80xxxxx, in an A3000T, WARP 4040 + 32MB,
- WB 3.1 (40.68), CyberGraphX 2.14, CVMon 1.33. I have the rev -11 Buster
- installed, but the older RAMSEY and DMAC chips. There is no FAST RAM on the
- A3000T motherboard (removed due to minor conflicts).
-
- The system randomly crashes with AlertPatch reporting errors like:
-

- This is a short list (what's in my static RAM drive at the moment), but also
- often includes stalwarts like CyberCron etc. This seems (to me) to indicate
- some kind of RAM corruption, though FASTCHECK seems to be happy with the 32MB
- installed.
-
- Removing the CV64 and replacing it with the GVP Spectrum removes 90% of the
- errors, making me suspect the CyberGraphX drivers/libraries (since some errors
- are still reported). However, the other possibility is that since both these
- cards are the only Z3 peripherals installed, with the CV64 being Z3 only (I
- also run the Spectrum in Z3 mode), the Z3 functionality of my system is still
- compromised somehow (regardless of Buster -11).
-
- Just wondering if anyone has any ideas that could be pertinent to trying to
- find out if I have a faulty CV64, a hardware conflict of some kind in the
- A3000T, or if it is just the software drivers.
-
- I have tried all sorts of things like "Setpatch NOAGA", "WARPKICK NOCACHEZ3"
- etc etc, removing patches and beta (and non-beta) software, changing Zorro slot
- positions, without any luck whatsoever.

-
- At the moment, I have the side of the A3000T removed, with a room fan playing
- directly into it. Closed up, the heat coming out of the PSU slots is scary (two
- HD's - one of them 5400rpm - DAT streamer, 32MB FAST, VLAB Motion, Toccata,
- TBCPlus, OpalVision, CV64 or Spectrum installed). The A3000T has two fans, and
- the CPU has it's own, but could the DMAC still be suffering from heat
- exhaustion?
