DDR3 10666 vs DDR3 1066

Need a little help guys here's my mobo memory specs:
Memory: 2x 240pin DDR3-1800(O.C.)/1600(O.C.)/1333/1066 DIMMs, Dual Channel, ECC/Non-ECC Un-buffered, Max Capacity upto 16GB

I accidentally bought a 10666 Ram stick even though the mobo didnt say it supported 10666, could that be why my newly built pc wont post?

Here's my budget gaming pc build:
PROCESSOR:
AMD Athlon II X2 250

Motherboard:
Asus M4N68T-M V2 Micro ATX AM3 Motherboard

Ram (memory):
PNY 4 gigabytes DDR3 10666

Hard Drive:
Western Digital Caviar Blue 500 Gigabyte 7200rpm

Video Card:
XFX Radeon HD 6670 1GB Video Card

Case (with psu):
Rosewill R218-P-BK-450W Case w/450W Power Supply
(Plan on getting a better psu but I gotta make sure the pc works first)
(Im like 90% sure I have everything plugged in right)

    well if you can return it you should, but since they are both ddr3 they should work. if i am not mistaken 10666 is ddr3 1333, a little slower than your 1600. but they should work, but the 1600 will run at 1333 speed.

    as for the psu, get at least a 550w, one of god quality
