memory upgrade from ecc to non ecc

[zapper]

Upgraded memory from 3 x 256 ecc to 3 x 512 non ecc. Get a blue screen /reboot some times on different programs. Will this be a regular occurance?

System is an Intel 1.5 processor

Any takers? Help

The problem could lie in the motherboard. The non-ECC memory might not be supported by your motherboard. What is the model number of the board? Is it pre-build or homemade? If it's pre-built, that is the compnay and model number. Also, did you get the same ram? DDR200 to DDR200, for example.

What is the model number on the ram?

 

[zapper]

It's from quality rams. They don't mention a model #
