Your posts are reminding me that I must set up and test my 3 (!)
4000VLCs. I really regret giving away my 4000/60 now. It's lost
somewhere inside Red Hat Farnborough. :'(

I think the 4000VLC takes 80ns FP-mode DRAM with parity.

Something like this:

(N.B. I think they don't know the difference between parity RAM and ECC RAM.)

Can you give us as much identifying info on your DIMMs as you've got?
Pictures on IMGUR or something would be helpful so long as they are
high-enough resolution to read the text.
