Not that I plan to, but the specs on my M/B say it can use ECC memory with certain cpu's.  Does E@H have any work units that employ this?

Try an Internet search on ECC

Try an Internet search on ECC memory.
My understanding is that no software can gain any performance boost from using ECC memory but the overall system stability will improve as memory corruption faults will be fewer or non at all, likewise the chance/risk of getting an error on a task because of memory corruption will be lower.

I don't believe so. One primary method used by E@H to screen for calculation errors is comparison b/w results from different computers ie. our quorum methodology. AFAIK both parity anomalies and bit correction are at the firmware level and thus for the most part 'invisible' to applications*.

Cheers, Mike.
