Man, I got to watch this thread and try to help fix this- I figured it would have gotten sorted out by my post or others by now. This is really a bummer that you can't get the system stable.
First thing, change "offset mode" on the voltage area to "manual". You can still leave the voltage fields to "auto" individually instead of a numeric value, but it's less confusing to have real numbers and not offsets. I still don't know for sure how offset works.
I had one time that this wasn't being solved and I couldn't figure it out myself. I actually just had to remove and carefully re-seat all of the RAM properly. The board's weird single-clip slots can make it possible to not get a good connection if you aren't used to them. I finally figured out that my board was crashing whenever the memory was busy enough to need the space from the improperly installed RAM. That's just a guess though.
The power is definitely high enough for you to be okay on the CPU side now. What I suspect *might* be the issue is actually your memory speed as it relates to your NB/HT speed. I'll be honest, I couldn't run the processor with memory speeds under 1600mhz without feeling it was on the edge, and that was with 2200mhz speeds on the NB and HT. Balance has to be kept so that one part of the workload isn't getting bottlenecked somewhere and causing the workload to hit a metaphorical brick wall at 4000 miles per hour. The CPU, NB, and HT clocks are all very high relative by default compared to almost any other chip on the shelf right now, and I just don't think that 1333mhz memory is going to yield great results here. You could always just try running the DRAM voltage at 1.55 and set the speed to 1600mhz in BIOS- my 1333mhz Kingston memory has no issues doing this inside of my X4 965 system.
The Sabertooth R2.0 is a great board from the specs and from everything I've read. However, it will likely have MORE options in BIOS that are highly advanced and not fewer. If it's a bad board or bad memory you have, I'd try to fix the issue first. If it's not an issue that is actually in need of an RMA due to defect, it's more than capable without the need to pay for the upgrade to the Saber. If you are considering it and this just gives you an excuse, then I say go for it.
PS- I won't have it for a couple hours since I can't really stop the F@H workunit that is running, but I'll take a screencap of each BIOS screen for my system and you can try copying the settings.
