AFAIK Crucial's BE2009 model is equipped with this ICs.
2. Samsumg HCF0 chips, capable of doing CL9-2000Mhz with lower voltage then D9GTS but not very good for extreme overclocking potential, still, cheaper. Most of the DDR3-2000 modules should be using this kit, like OCZ, etc.
3. Elpida MNH-E Hyper chips. The most expensive one, but they're capable of hitting 2000Mhz with very low voltage like 1.6v.Also they're mostly come with 3 channel kits. If you may conside ugrading to i7 sooner or later by any chance you don't need to replace your dram module again. I'm sure Elpida ICs will still work fine on Rampage Extreme.

If you're looking for some cheaper modules that have great value, I'll say, crucial values most likely will give you surprise. Some of 2GBx2 modules equipped with D9JNM can do CL7-1800 without a problem while they're only rated at CL9-1333
Thanks alot for fast replies.

Actually, my mainly concern is DDR3 memory compatibility of Rampage Extreme x48. I already checked the QVL list and it shows the slots as A/B/C, I dont understand that yet. It shows the DDR3 2000Mhz compatibility to the Corsair 2048 (Kit of 2) Box P/N TW3X2G2000DFNV (CM3X1G2000DFNV) only for B DIMM Slot.

I suppose I'll prefer to the Crucial 2000Mhz with RE x48 soon.

I also really want to know who using the Crucial 2000Mhz below with Rampage Extreme x48? Someone should use them before.
