Just got this board!

I have a few questions before building my computer:

- The low mmio align option: Should I mess with that or just leave it as it is? I'm using Windows 7 64 bit and Ubuntu 11.04 64 bit. No overclocking.

- I got 8gb (2x4gb) RAM. It's DDR3 1600, 8-8-8-24 and 1.5V. For this board do I have to manually put the clock speed and timing or will it recognize it right away. If I do have to put it manually, how/where is it done? Oh and that 1.5V, do I have to enable some other option for that? Thanks!

- Also, should I use the drivers cd or just let Windows recognize it?

It's supposed to come with 6 standoff screws but I don't see them anywhere.

1. No need to change MMIO, it'll be just fine.
2. Just load the XMP profile.
3. Its worth downloading the latest drivers from the relevent sources

I have some question about the fan control in AXTU.
Is it supposed to Auto control the fans? or just the manual fan speed changer?
I have CPU fan connected to both of the CPU fan sockets. (1with 4-pin PWM, other is just the 3-pin)
Even I have the 4-pin PWM fan connected to 4 pin CPU fan socket, all it does is going for 100% all the time even where it is at less than the "target temp".
Is it not working or am I using it wrong?
Also there are 2 cpu fan sockets. I'm assuming the information from the 4-pin PWM controls the 3-pin side along with it.
(for using dual fan HSF like 212+, noctua NH-D14.)
Let me know if anyone know how to make this work.
Or do I have to use SpeedFan or some other app to do this?

1. The CPU fan headers are controllable, the 4 pin header is there for the benefit of the intel stock coolers mainly but can be used with just 3 pin fans too.
2. AFAIK, the PWM fan header isn't controllable. Using Speedfan might work on it.
3. Just in case, don't connect any fans to the 4 pin auxillery header. Its meant for supplying additional power to the system and while connecting a fan to it isn't likely to do any harm theres no need to cause possible problems for yourself

Thanks! What exactly is 1t/2t (1n/2n) and where can I find out which one my RAM uses before installing the sticks?

Any downside to manually putting the voltage or is it preferred?

Oh and also, the clock speed. Is that something I'd have to put manually?

1. 1T/N and 2T/N are basically command rates. 1T/N is more agressive than 2T/N so will give better performance, your sticks will more than likely be 2N.
2. As above, load XMP profile.
