dual channel kit: use three of them for triple channel?

post #1 of 9
Thread Starter 
I have the opportunity to purchase three CMG4GX3M2A2000C8 kits for a pretty good price. These are dual channel kits at heart... but if I were to purchase the three kits for a total of 6x2gb, they will probably perform at triple channel.

But is that advisable? Or should I try to procure some true triple channel kits?

It'll probably run just fine - worth it if you're getting a good deal anyway.

don't think it will work

just to let you know, you can still run dual channel on LGA 1366 mobos if you folo the mobo manual with minimal performance impact unless your doing loads of mem benchmarks

It works fine.

I am bought two sets of 2x2GB OCZ Gold DDR3 ($90 AR!)..... 3 DIMMs in my i7, 1 DIMM in my AMD HTPC. I know they are the same revision and their serial numbers are within 10.

A "Dual-Channel" or "Triple-Channel" kit is just modules that are certified to work together. They basically have the same ICs, stock voltage, clocks, and timings. The actual channel aggregation is done by the memory controller.

hmm really?
so if I bought a dual channel kit and just found another stick from teh same brand say g-skill as long as the mhz, CL, volts and everything are the same I can grab another stick and just stick it together for tri-channel?

awesome

Yes, the memory controller won't know the difference. (You do need an i7 for Triple-Channel though.)

Make sure the revision is the same as well.... sometimes companies change the ICs but not the model number.

^^^ this. As long as the stick are same branded, model, and etc they are most likely going to work fine. I can't speak for different branded stuff.

basically if you buy all 3 kits from the same place, same time, most likely they will be the same models, from the same batch. So in this case it shall be fine.

What determines dual or triple channel is the motherboard and IMC, not the ram sticks themselves.

Like people have mentioned, dual or triple channel is determined by the memory controller when you boot up depending on which DIMMs are populated. As long as the memory sticks are identical, you can buy three individual sticks from different places and have it run just fine in triple channel. But buying them all at once from the same place increases your chances of ensuring that they're identical sticks because having the same model number doesn't guarantee identical memory sticks (as it's been mentioned, sometimes the manufactures change the ICs while keeping the same model number).

Also, 6x2GB running at 2000 MHz is a lot of strain to put on the memory controller. That might require a lot of VTT to make that run (if it's even possible?).
