Yeah, the ram card is defective. I have seen that with regular memory on a pc. Even when the ram test at the start didn't pick it up if you run himem in something earlier than windows 95 it will detect if you have bad memory. Under normal circumstances windows 95 doesn't test high memory. To do the test under win95 press F8 when Starting Windows 95 appears and select Safe Mode. That will force it to test memory. I fought installing Windows NT on a machine for a week. For some reason I decided to install Dos 6.22 and Windows 3.1 on the machine. That is when I found I have a bad memory simm.

Subject: 755CV and RAM card
I'm trying to install a 16MB "credit card" memory card into a 755CV, which
has 8MB onboard. The card is a Kingston KTM-750/16. Halfway through
booting Windows I get a blue screen message: Memory parity error detected;
system halted.
It was suggested to me to disable parity checking by going into setup,
clicking memory, then disable parity checking. In that case I get these
messages:
"himem.sys has detected unreliable xms memory at address 00c20000. xms
driver not installed.
to continue starting your computer, press enter"
Next comes:
"himem.sys is missing
make sure that the file is in your windows directory"
Then:
"Windows has stopped. Press ctrl alt delete to restart your computer."
Then:
"While initializing device VREDIR:
windows protection error. you need to restart your computer."
Removed Kingston card, rebooted, everything back to normal.
Any ideas?
