BIOS updates are not only used to fix RAM settings, they are used to workaround known bugs in the CPU electronics, and chipsets used on the motherboard. If you have issues that look like hardware issues picking up the BIOS updates is one of the first things you want to do.
Most bugchecks are not caused by hardware defects. Even a bugcheck that indicates memory corruption does not mean the system is complaining about your RAM. It is complaining about a location in memory that has the wrong contents in it.
Thanks for the reply! Assuming it doesn't void my warranty (I don't think it does, but a quick call can confirm that for me) I'll try flashing my BIOS tomorrow and update. I bought the board when it was fairly new, so it's running one of the very first versions. Maybe something this simple really is all it needs.
And Alec, I don't think they make my board new anymore so if I RMA'd I would likely get a refurb. That, or I would get incredibly lucky and they'd send me an R2! I don't mind troubleshooting, really. I'm pretty patient and enjoy the experience it gives me. My issue is not particularly frustrating... yet. I just ran out of ideas. And I still have another 2.5 years on the warranty. I'll definitely RMA if it becomes more frequent and nothing I do fixes it, but I want to exhaust other non-warranty-voiding options first. I appreciate your help! I'll be sure to manually set my RAM's timing, etc. Allowing the mobo to auto detect it was pretty lazy on my part, in hindsight!
