2. My Daystar 128K Quad Cache (aka FastCache Quadra) does not work in the overclocked configuration. The Daystar QuadControl v2.3 init hangs at startup. Unlike the IIci cache card, the Quad Cache card is not enabled until the software kicks in.
2. Sounds about right. I don't know where it is, but there should be an 040 cache thread with info, or Bolle might've chimed in earlier in the thread, but I believe the long and short is that the wait state config on the cache cards is definitely made to work with stock Quadras (not sure about the 840av, since it's a completely different beast), so 33 and below is likely the target.
Apologies for going a bit off-topic, but you two seem to know a bit about the FastCache Quadra and I haven't found much solid information about it before now.
I have one, and installed in my Quadra 800 (modified 650 board, my original 800 board has dead SCSI right now so I can't test it in that one) running 8.1 I can't tell if it's working or not. It gets warm, and the control panel says it's enabled, but tattletech doesn't report anything in the PDS slot, nor does it report any additional L2 cache, and benchmark scores seem unaffected.
The only hint I have seen that it might be doing something, is that it won't enable (greyed out) in the control panel when I have my Silicon Express II card installed as well.
Do you guys know what's up with that? Is there a definitive method to tell if one of these cards is actually enabled or not?
