Arrgh... I tried increasing the voltage to the RAM step by step until 2.8v, and it still wasn't stable at 216mhz. I'd get on the system and run SuperPI and my screen would flash black a few times so I'd reboot and up the voltage. Since 2.8v was a good bit higher than the stock, I decided to lower my overclock on my CPU from 2.6ghz to 2.55ghz and set the vcore to default and also set my RAM's voltage to default. That puts my RAM at 212mhz. The odd thing is, it's running fine at 212mhz on stock voltage but a rather good increase wouldn't let it run at 216mhz... rofl. Doesn't seem like this RAM is much more than value RAM for overclocking
Anyway, I ran several 1M SuperPI's and the system is stable (33secs is the best one). I didn't run a memory test, but since the memory was causing the flashing before, that seems like an indicator that the memory is fine now. If any problems occur, I'll just do a bit of twinking to try and get it stable.
Anyway, thanks for the help guys, but I don't think increasing the voltage any higher than that for a chance at a very minimum performance increase would be a justifyable thing to do. I'm going to settle for the overclock I have now; even if it is under par
I think I might get higher performance RAM on my next build though.
