parity check 2

I hope someone can explain this to me. I get it when I boot up. I have to turn it off and reboot until I don't get it.
I have a deskpro en p733
I am running two 128/133 ram but one is double sided and one is single sided,maybe this is a problem? I upgraded the bios 3.14 and still I get the message.

Re: parity check 2

Try testing it without the double-sided module. That will confirm or refute the possibilty of the combination being the cause. Question...Does your setup have the option to run parity check or not run it?

Re: parity check 2

Parity check 2 is an old error message, left over from the days of the original IBM PC - the 5150. In those days systems had memory on the system board as well as memory expansion cards. A parity check 1 indicated the problem was the system board memory, whilst a parity check 2 was expansion card memory.

Mixing single & double sided has not caused problems for me.

It is possible that you have defective or incompatible memory, I would try running it with them interchanged and one at a time and see what happens

Re: parity check 2

Some older computers don't recognize the higher-density chips on the single-sided one. Otherwise...as long as they both work, they're the same.
