To ECC Or Not To ECC?

MetaHiro asks: "I'm going to be upgrading my system in a couple of weeks. I've been looking around the net for reviews and/or benchmarks for ECC vs. non-ECC in both speed and whether or not it's worth it to shell out the extra bucks for ECC. I'm also wondering whether or not i should buy PC2100 ECC instead of PC 2700 non-ECC ram or wait until PC2700 ECC becomes available."

Re:I can't understand ECC - specifics

Thank you for that explanation - I think I understand it better, though I'm confused a bit because the two times I've gotten a BSOD were with ECC enabled, which is why I turned it off to see if they would go away...

I've got a Tyan S2460 MB w/ 1Gig PC2100 ECC RAM & 2 1.4Mhz Athlon MPs. It uses PhoenixServer BIOS, and the BIOS gives me these options re: ECC

SERR Signal Condition: (ECC error conditions that SERR# be asserted [sic])

• None
• Single Bit
• Multiple Bit
• Both

ECC Config: (No ECC, Checking Only, Checking and Correction and Checking, Correction with Scrubbing)

• Disabled
• Checking Only
• Checking and Correction
• Checking, Correction w/ Scrubbing

So, my question would be: if this is basically a home machine with no mission-critical stuff running on it, but I'd like to get some benefits from my expensive ECC RAM without BSODing, what settings would be best in this scenario? Right now I've got everything turned off (Signal Condition: None, ECC Disabled). Oh, and what the heck is scrubbing?

And yes, I've attempted to RTFM but it's little more than a pamphlet and I can't find good, clear info about this.
