DDR3 1066MHz - DDR3 memory that can run at this spec

[Turbonium]

What DDR3 memory can run/downclock itself to 1066MHz (anywhere from 1.35V to 1.65V) on its own (i.e. by default).

Memory doesn't clock itself by its own, is always the BIOS the one that decides at what Frequency/Timmings/Voltage will run it. Memory Modules got a SPD Chip that usually comes with multiple configurations, most JEDEC standard profiles, that allows the BIOS to read it, and pick one that is under its default specs, to guarantee automatic compatibility.
Now, I suppose that ANY memory module would run at 1066 MHz. However, in what platform you're intending to use it that you need that? Mainstream minimum is 1333 MHz.

This, buy a 1333 1.5v kit, run it @ 1066 1.35v.

The memory will have that table of values, that it 'broadcasts' as available choices. You could always deviate from it and manually set the values in the BIOS, but it would be helpful if the memory itself stores a table entry for the 1066 speed and corresponding timing values. Maybe someone has compiled a list of memories that have those table entries.

CPU-Z utility can show you the entries. I'm running mixed ram sticks using 2 different brands, and one brand includes an entry for 1066, but the other doesn't.
