"Single-Bit ECC Errors in Memory Bank"
At bootup I see the message "Single-Bit ECC Errors in Memory Bank", but I am able to proceed with booting and nothing seems wrong.
I assume that at least one of the banks of ram is bad (I think I have either 4 or 8 banks in there).
Should I pull one out at a time until I find the broken one (and then replace it) or is it safe to just ignore it? If I can ignore it, is the speed of the ram impacted by this at all?
I don't know if my type of memory corrects single bit errors or simply detects them.

The inportance of a good CAS match to the MB chipset is one of THE most important issues for stability. Single bit ECC errors in this case are more likely related to the MB chipset not liking that ECC Ram, but the CAS issue is still supremely relevant. With the wrong CAS, this is what you can get with ECC.

This is all useful information, but for some reason the message stopped coming up during booting. I've been waiting to see if it reoccurs, but so far it hasn't. I obviously can't go in and change things in order to fix it if it isn't giving me any messages to indicate that it's still happening, so I guess I'll close the question.
I tried memtest86, but it didn't find any problems and I haven't seen the error during bootup since I ran it.

It may have been heat or any condition. One bits are flakey, but it will return one day, count on it.
If a minor (one-bit) memory error occurs, the ECC logic will handle it. If a two-bit or larger error occurs in ECC memory, your system will be halted--similar to what happens with parity memory when any error is encountered.

Or you can download a third party memory testing software to find the fault
