I have 3 PC's, all some-what different from each other, I know a little bit about PC hardware, I want to install more RAM in this PC, I have another PC which I use for parts, this computer uses 168pin 100Mhz SD-RAM with ECC (Error Checking Correction), now, the PC I want to use the RAM from has a FSB of 66Mhz, but the RAM is 168pin 133Mhz 9Dont know if ECC is supported) it has no harddrive, so I cannot run any benchmarking utilitys, will the RAM off of that PC, work on this one?
If you are running PC133 on a 66MHz FSB, it should also work on a 100MHZ bus. As far as the ECC and non-ECC compatibility goes, it depends. I'd plug it in and try it with ECC enabled in the BIOS. If it won't boot, or boots and won't recognize the added RAM, go back into the BIOS, disable ECC and reboot. This may or may not work: I've never tried mixing ECC and non-ECC RAM.
