Hello,
I recently purchased a few parts, here is my system:

EVGA GTX 460 768MB DDR5
Cooler Master NV-690 Nvidia case
Cooler Master Hyper 101a cpu cooler
Okia 550ATX 550w generic power supply
Samsung 80GB Sata Hard drive

ECS A785GM-M (arrives on Thursday)
AMD Phenom II X3 740 OEM (arrives on Thursday)
Kingston HyperX 1GB DDR3 KHX1800C9D3/1G 1.7v-1.9v (arrives on Saturday)

Ok so I look around for compatible ram and find out over 50% of people say 1.5v DDR3 ram IS NOT compatible with this motherboard. But MANYYY people have successfully used it with 1.5v memory. I've searched everywhere so this is my last stop. Now one person said to put one stick of ram first and change the bios settings to 1.6v or more. This probably works. Well CLEARLY 1GB is not nearly enough for this system. I did not have enough money left for a 1.6v 2GB ddr3 ram stick so i went with the kingstion 1GB. Now what i want to know is if i buy 1.5v 2GB DDR3 ram stick and change the bios settings to 1.7v, will the ram run fine? Im talking about cheapo ebay ram. Will it run fine at 1.7v? Will it even work even after changing bios settings? my guess is it will run fine after changing bios settings to 1.7v and then installing the new 1.5 stick.

Ok now for my second question, is this ram any good for overclocking. It is at a very fast 1800mhz stock. It looks really good too! :D 

Thanks :)

Hopefuly, you reviewed both the Certified or Tested lists prior to purchasing your RAM. ALL of the RAM on the Kingston list is 1.5v! The 1800 MHz RAM is typically compatible with 6-core AMD CPUs, and with the 3/4-core your going to run into DIMM slot issues -> "Single-channel memory configuration"

Hmm...You need to but them in SETS and not pseudo sets. If you bought 4 single 1GB sticks that does NOT make a 'Matched Set'. If you purchased 4 then statistically you've got a slim to none chance of the working at all or properly. Sure 2 of the 4 will work but the other 2??? Now add to the mix 1800 MHz with a 3-core - yikes.

If I had your set-up KHX1600C9AD3K2/4G -> http://www.newegg.com/Product/Product.aspx?Item=N82E168...
