Vicey do you know if the x58 is like older platforms or closer to SB??
My 775 machine won't jump straight to DDR-800 I need a 4.2GHz overclock with a 4 to 5 memery ratio or no overclock at all with a 1 to 1 ratio which sucks pretty bad in bench marks??
Milo I was gonna say if it's closer to my older machine you might not get straight to 2000MHz, you might try clearing your CMOS and doing the timings and voltage manually for what your sticks are rated for at 2000MHz, and take them up one standard speed at a time 1066, 1333, 1600, 1866, etc..
this is the best way if you don't have a lock free BIOS, if you type in you want 2000MHz on yor memory, and that requires an overclock higher than your CPU can handle, your BIOS will be smart enough to try, though it will fail....
If you get to 1333 and you get it to boot run it a while and see if its stable, check and see if your CPU is overclocked or not.... it's all about little steps man, don't just jump in and expect 2 GHz on your memory for just the price of paying for them , you gotta work alittle for it, and we are here to help.....
also don't rule out a bad stick, it happens all the time.... what you will have to do is test each stick one at a time, if this is the case.....
if you got it working nevermind what I said, if not give it a try, i'm sure thats what corsair is gonna tell you anyway.
