The F3-10666CL9D-4GBRL http://gskill.com/products.php?index=225 should work. I assume you're using the 'red' DIMM slots.

You've got a high-end MOBO with 'budget' RAM. Try increasing the DRAM Voltage +0.05~+0.10v or 1.55v~1.60v.

I can't increase the DRAM voltage if the system won't boot to bios settings because of the RAM. I tried all the DIMM slots nothing I the RAM also isn't on the compatibility list in my manual for the motherboard so I guess that's another reason. I'll check to see if those RAM sticks are compatible with my board I wanna get my gaming PC up an running so I can play all the games I purchased or plan to on steam.

Edit: Also I don't see Asus Crosshair formula V listed on G.Skills site but I do see it in my motherboard manual which makes me think it requires a Bios update with previous hardware or something.
 
Again, the RAM should work unless it's bad, try (1) stick in the first red DIMM slot, failure try the other stick same slot, failure use the MemOK button on the MOBO. You're first saying it won't boot - "doesn't detect it" can mean one of the sticks is failing.

You may simply have a 'bad' stick or rarely 'both' are bad.

ASUS did update the QVL list, but it's by no means a 'complete' list and G.SKILL has no Tested list for your ASUS Crosshair V Formula 990FX.

Same IC's:
F3-10666CL9D-4GBRL ; not on list
F3-10666CL9D-8GBRL ; yes on list TWICE ?

Then quit screwing with it and RMA the RAM for something on the QVL list...

I tried all the slots and the 1 RAM stick method, I'm already working on getting a new pair of RAM thanks for your help.

NewEgg just had a shellshocker on G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-8GBXL
and I order it is that bad? I saw a review in their saying it worked with their Asus.
 
Since the 'QVL' and 'Support' was such a concern then I'd stick to the QVL list. The F3-12800CL9D-8GBXL doesn't even list ANY AMD Chipsets -> http://gskill.com/products.php?index=355

QVL -> http://usa.asus.com/Motherboards/AMD_AM3Plus/Crosshair_V_FormulaThunderBolt/#MSL

QVL:
F3-12800CL7D-8GBRH -> DEACTIVATED
F3-12800CL7D-8GBXH -> http://www.newegg.com/Product/Product.aspx?Item=N82E16820231431
F3-12800CL9D-8GBRL -> http://www.newegg.com/Product/Product.aspx?Item=N82E16820231314
F3-12800CL9D-8GBSR2 -> http://www.newegg.com/Product/Product.aspx?Item=N82E16820231461

Alright I got my PC up and running I did the 1 stick method first and the PC started booting up but I have another 4gn RAM when I put it in and press the memok button when it atarts up and in the bios it doesn't get detected and I put it in the parrael DIMM it's mean't for. How do I get the second stick to work
 
This is QVL oops or the MOBO's issue. I simply posted the QVL; IMO 1.25v RAM is 'too' low voltage, but blame ASUS ;)

IF you have an aftermarket HSF with a metal backplate then that backplate shouldn't be in direct contact with the MOBO and 'some form' of non-conductive material e.g. plastic washer or similar. As I said, "I assume you're using the 'red' DIMM slots."

Otherwise it's time to quit blaming the RAM and Breadboard as follows or a full Breadboard.

Anytime I build the build is tested on a bench first, Tested & Benched, then installed in the Case.

You can try Lazyman's Breadboard -
* Disconnect ALL Front Panel & USB Headers ; keep only the PWR & Ground <best> short w/wire.
* Disconnect ALL peripherals including the Keyboard/Mouse
* (1) Stick of RAM in the second DIMM slot from CPU
* Unscrew both the MOBO and PCIe screws

Pull the MOBO away from anything conductive and supported by a towel ; short PWR & Ground to start.
