i7 Memory Question (Quick Responses Please)

422 Views 8 Replies 7 Participants Last post by  lsdmeasap
I need anyones help with this question. I just ordered a 1366/i7 rig. If you look in my sig, you will see 4GB of G-Skill 1600 ram. I only had two sticks, so I ordered another set of THE EXACT SAME memory. If I use 3 out of the 4 identical sticks, this will work in tri-channel correct? I'm 99% positive it will since the modules are identical, but I need to know quick in case I need to cancel part of the order.

I'd suggest an actual tri-channel kit.

While in theory 3 of 4 chips should work, the tri-channel kits and binned and tested together.

Help me out here. So do you think it would work?

nope it needs to actually be tri chanel memory

You can't be sure that you will get the "THE EXACT SAME memory." Manufacturers have different revisions over time. So while the product name/model maybe list the same, the ICs used may differ.

No, it does not. Tri Channel is a fuction of the controller. There is absolutely no difference in a tri channel memory DIMM vs a standard DIMM.

Duckie is dead on.

It might work and it might not. Two different kits may have different IC's which could lead to instability even at stock speeds.

This is why when you buy a dual channel or tri-channel kit of ram, somewhere on the package they typically mention that the chips were tested together.

Yes, this will work.

In fact you could use all four and still have triple channel.

Every single matched set of memory I have ever purchased (about thirty) had a wide variance in max stable frequency and/or voltage required between the sticks. Last triple channel kit I bought had one stick that did DDR 1990 at 1.5v and one stick that did DDR 1640 at 1.5v, and not a MHz higher (didn't complain as these were 1333 sticks).

They test them to see if they work, then they package them together, and that's about it.

Personally, I prefer to buy my sticks individually, if it's not much more expensive. I can test them and bin them much better myself, and if one craps out I don't have to send back a good chunk of my memory.

This is true, but if the ram is bought from the same place without too much time between they are likely to be the same revision/IC.

Then again, on more than one occasion with cheaper memory, I've gotten different ICs in the same triple channel kit... heck, my Buffalo sticks had different PCBs in the same set as well.

You also really do need 1.65V memory for X58, of course you can often undervolt higher rated kits but this may or may not work.

I Agree with the lot here, to save yourself hassle in the long run, it's best to order a triple channel kit now.
