Greetings
Several hours of reading the web and I still cannot overcome my density.
I'm looking at a Socket 939 motherboard with one single-core Opteron 148.
Be careful - the cheap mobos are usually not tested with ECC. I don't know if ECC can cause problems, but normally it's best to only use DIMM configurations that have been validated by the motherboard vendors (they tend to document that on their websites as "approved DIMMs" or similar)
The motherboard supports ECC or non-ECC RAM The BIOS can turn off ECC if the RAM supports it.
What is the kernel's involvement with ECC when it's enabled in the BIOS? Just reporting errors?
Yes.
Does ECC RAM incur a performance hit when no errors are detected?
Memory latency increases slightly, but not much. -Andi
