Well will have to get back to you on that since I don't have a monitor atm, but since my board is constantly giving me a 1:1 ratio (unless I use a modded BIOS specific to a certain ratio) I need to set it passed 200MHz (400MHz) so that I can achieve the performance I want and need, but the RAM won't go passed that and neither will it want to stay at 400MHz =/ I also stick to the 1.70 BIOS because, as TRWOV has mentioned, it handles Quads better than the 1.60 BIOS versions.
Now it could also be cooling and I'm just jumping the gun, because not much airflow goes past my RAM, except for the air from my CPU's heatsink that towers over the RAM slightly.
Even that said though, 1:1 is a good Ratio, and I need RAM that can handle frequencies past 200MHz. When I first used the RAM, it wouldn't go past 215 CL3, and at this time I had decent air flow and cooling, until some unfortunate events happened to some of my air intake, which is most likely why I ended up having trouble even hitting 400MHz without errors.
Thing is though, to save some cash, I would like to run on the 5:4 ratio, but 1.70 doesn't support 5:4 and because 1:1 is really good performance, running on the OCZ that could possibly hit 225 CL2.5 would do really well in achieving some great performance.
