It's like... the next multiplier. 1066 is 8x, and 1333MHz is 10x.

If you are attempting a true overclock you need to experiment with settings to find a stable one, as Jonathan says.
The other possibility is bad RAM. It runs stable at 1066 but craps out when you try and run it at the label speed.
What is the beep code being emitted? Most likely it is a RAM beep code, but it could be something else.
I know what you mean by auto... it's set on that value by default.

You can also set the temperature warning ranges in BIOS slightly higher. This stops most apparently "random" beeps. You should not overdo it though, the audible warnings are there for good reason.
"Simple" overclocking of RAM is basically pointless and merely increases the risk of failure. If your RAM wont run at factory specified speeds, then it is possibly defective. Overclocking can also damage the RAM so that it then runs at even lower speeds.
My Windows 7 Power settings are set to Max already. I actually disabled temperature warn for now though... Well, I was able to run my RAM, stable, for a couple of days no problems before last night.

There should be a beep code list in your motherboard manual.
There's a single short beep at POST. I remember that means "OK". When it happened, it was a mix of short beep and half beeps. And Windows was running perfectly stable.
For the "overclock", I asked the Gigabyte forum before going and do that. Here is the thread : X58A-UD3R downclocking RAM [Plz read!]
I did what they said and exactly changed to this :
Uncore : 20x
Memory Multiplier : x10
DRam Timing : Expert
And set each channel to 9-9-9-24
Of course, the voltage was already 1.5v
Anyway, as of now, there are no problems and memory is running at mobo default of 1066MHz.
