Mixing ECC and Non-ECC RAM: Unsuccessful

[elzmaddy]

I'm writing this for people that will use the search feature to look up information about this issue.

I was unsuccessful at mixing different types of RAM (ECC and non-ECC) together.

Original stick of RAM: Crucial PC2100 256MB 32x72 DDR REG ECC
New stick of RAM: SimpleTech PC2100 256MB 32x64 DDR (non-ECC)

The system emits two long beeps on power-on and will not continue or display anything. And Yes, the SDRAM Error-check setting in the BIOS was on "Disable."

I wonder if non-registered ECC and normal ram would mix??

 

[Kingofcomputer]

reg and non reg = no
ecc and non ecc = yes (disable ecc in bios, or if the motherboard chipset doesn't support ecc, it doesn't care.)

Oooh man. I thought ECC and Registered meant the same thing. Apparently not: What are ECC, Buffered and Registered SDRAM?
