I highly doubt your ram voltage is at 1.094
That would be only about 50% of the stock voltage. It's fine to run it at the stock voltage, it's high enough to keep it stable at stock speed and it's low enough so that it doesn't break the ram.
If you are running the ram as ddr2 800 then you can probably lower the voltage a bit if you want to. This won't really do too much, just causes a bit less strain on the ram, lowers temps and decreases power consumption a bit. Just don't go too low or it won't be stable.
And then if/when you overclock you might have to increase the ram voltage to something higher than the stock to keep it stable. But since the rams stock speed is 1066 it should work fine at that speed with stock voltage.
But like I said stock is good enough and it will work just fine. No need to change it if you don't want to. And like I always say, if it's working just fine then you don't need to worry about it.
Atm my own ram is running at 850mhz and I'm pretty sure it's still using 2.0v when the stock was 2.1v.
