I take out the ram and it peeps constantly, which is a sign the ram is bad or incompatible.
So i take a 4gb stick of vengeance and put it in I get the same thing as before black screen, no POST peep, and red DRAM light.
So after thinking about it I figure it needs a BIOS update but i cant get it to POST so i dont know what BIOS version it running. I go to Asus website to see how i can check and it tells me to look at the motherboard by the model but all i see is the revision number which is 1.02.
The newest BIOS update is 0906 but how do i check to see if Rev. 1.02 has the 0906 BIOS, I've tried everything the best i can come up with that it might be 0802 BIOS.
Oh I also already ready replaced the Mobo and CPU and it still cant get it to POST.
What is the part number on your Corsair Vengeance RAM? Am I understanding that you are trying to fully populate all 8 DIMM slots with 8 GB memory modules for 64 GB total? (And are you aware that your system would probably be considerably faster if you stuck to only 4 DIMMs for good quad-channel performance without overloading your IMC. 4 x 4 GB = 16 GB total should be smoking fast on your system and provide you with more memory bandwidth and size than you will most likely ever need.)
I'm willing to bet that the RAM that you're trying to use isn't entirely functional with that board and that BIOS version. Try setting your BIOS manually (with only one memory module installed) to underclock your memory and not to use SPD or automatic settings and see if that helps you POST.
Check the QVL (Qualified Vendor List) at this location: http://www.asus.com/Motherboards/Intel_Socket_2011/SABERTOOTH_X79/#MSL
For Corsair, it lists the following:
CORSAIR CM3X2G1333C9 2GB DS - - 9-9-9-24 1.5 (4 DIMM or 8 DIMM)
CORSAIR TW3X4G1333C9A 4GB ( 2x 2GB ) DS - - 9-9-9-24 1.5 (4 2 DIMM only)
CORSAIR CMX8GX3M2A1333C9(XMP) 8GB ( 2x 4GB ) DS - - 9-9-9-24 1.5 (2 DIMM or 4 DIMM)
CORSAIR CMX8GX3M4A1333C9 8GB(4 x 2GB) DS - - 9-9-9-24 1.5 (2 DIMM or 4 DIMM)
Crucial BL25664BN1337.16FF(XMP) 2GB DS - - 7-7-7-24 1.65 (2 DIMM, 4 DIMM, or 6 DIMM)
So since you said that your sticks are 8 GB sticks, my guess is that they are simply entirely incompatible with the board. You're trying to run 64 GB and that's unlikely to work.
The only 8 GB DIMM module that I've seen which appears to be compatibile is this one:
SAMSUNG M378B1G73AH0-CH9 8GB DS SAMSUNG K4B4G0846A-HCH9 (2 DIMM, 4 DIMM, 6 DIMM, or 8 DIMM)
Note that Asus recommends installing the DIMMs in the following manners:
2DIMM B1 D1
4 DIMM A1 B1 C1 D1
6 DIMM A1 B1 B2 C1 D1 D2
8 DIMM (fully loaded DIMMs)
