Asus Crosshair IV Formula

Hello

Ok, so I am building a new computer and everytime I look at components for high-end build most of the parts aren't even compatible... So I was wondering if I take an Asus Crosshair IV Formula and add a Phenom II x6 T1090 3.2GHz that means for ram I have to look into Asus.com for the QVL and in Crosshair IV Formula 6-core CP it doesn't show anything below DDR3 2000 (PC3 16000) at least 8GB (2 x4GB) with a max of 7CL

Does that mean I have to pick any of these:

CROSSHAIR IV FORMULA

● Team TXD32048M2000HC9-L(XMP) 2GB DS TEAM - 9-9-9-24 1.64

All of these are terrible with high Latency and none 2 x4GB (2 slots empty for later upgrade to 16GB), so basically I am screwed and I need to do a lot of modifications if I want at least a 6 core 3.2GHz + 2 x 4GB DDR3 1600 (PC3 12800) CL7?

Then say I go and pick these: ● G.SKILL F3-16000CL9D-4GBTD(XMP) 4GB(2 x 2GB) DS - - 9-9-9-24 1.65 that means I have to overclock the motherboard and make it 2000? why didn't the dumbass developers think of that before they made the motherboard limit 1333 Non-Overclocked?

The mb supports lower than 2000.
There's too many vendors to qualify so whatever good brand you choose should work.

I understand the motherboard support from like DDR3 1333 to like DDR3 2000, but with a Phenom II X6 CPU will it still support below DDR3 2000 cause that's what got me confused, the QVL doesn't list any ram below DDR3 2000 with a Phenom II X6
 
Well technically the Phenom II memory controller supports up to DDR3 1333 by JEDEC standards. Motherboard makers just give them higher dividers in the bios to run higher speed memory. For the price and performance DDR3 1600 is about the best deal.
 
I'm using what's in my sig with that mobo, but i'd have no hesitation with getting some 1333 or 1600mhz in it's place. I later learned that I wouldn't actually NEED the ram to be quite this fast, and wanted to get the x4 instead, but this ram calls for the x6 so I guess i'm stuck! The memory controller by default will run 1333 at highest, but depending what speed you buy, you can overclock it higher. Hope it helps some, and I will be getting the same x6 processor as you, it looks like.

Depends on the timings, CAS9 is slow-ish for 1600, CAS8 and CAS7 is much better and faster :)
