Legitimity of a "supported memory" list ?

I think I just found out something a little funny, or perhaps more on the ironic side of things, concerning a supported memory models list for a specific motherboard. Here's the thing ... take that motherboard as an example (which happens to be my new one as well, I'm running a nice temporary system on it until I buy my own parts for my next build): http://www.giga-byte.com/Produ...ew.aspx?ProductID=2665

Right, that's the Gigabyte X38-DQ6. Now, on the right side of that web page there is a "Related Links" board, and one of them being "Memory Support List", and here's the direct link to it: http://tw.giga-byte.com/FileLi..._memory_ga-x38-dq6.pdf

Take the 1066Mhz category for this cause, with the specific OCZ model OCZ2N1066SR2GK. Now, OCZ has quite a nice variety of DDR2 modules at 1066Mhz, but there's the actual model officially "supported" as shown above: http://www.ocztechnology.com/p...y_edition_dual_channel

You guys notice something ? If not look carefully. That memory, which Gigabyte officially supports on their X38, is SLi Ready. Now, I usually don't jump right away to conclusions but ... isn't the GA-X38-DQ6, an X38-based motherboard NOT supporting SLi at all right out of box due to Intel refusing to let X38 support SLi ? I'm pretty sure that I've read something about that somewhere. That SLi MIGHT be supported, un-officially, by some type of a device (SkullTrail ?) that's not even released yet, made by neither Intel nor NVIDIA. And that right now ONLY ATi's (or I should say AMD's) CrossFire is supported. Now, OCZ does have a CrossFire Ready module, but it's not on the supported memory list ... not only does making memory SLi and/or CrossFire "ready" doesn't really makes sense to me, but seeing Gigabyte telling me by that list that my motherboard supports something that the maker of the chipset that's on the mobo doesn't support ...

Any thoughts ? Am I just plain wrong on all the line ? If so please do correct me, I just want to understand why would Gigabyte test a memory that's supposedly "better" when coupled with SLi, when they explicitly known (well I do hope so) that their own X38-based mobos don't support SLi at all.

"SLI ready" memory exists in marketing-land, not in reality. It's a rubber stamp from NVIDIA that means little if anything. Gigabyte most likely tested whatever memory they happened to have on hand or OCZ was willing to provide, which happened to have an extra green-black-and-silver sticker on it.

You are reading too much into this.

I see.

Well, on a side note, do you think that buying ANY models/brands of DDR2 would be "safe" or do I really have to consider that "support list" or else I could run into stability/compatibility troubles ? Because right now my (friend's) temporary memory (from Kingston) is listed on that list, the 800Mhz model that is, but when I buy my own I will have to make 100% sure that my choice will be safe. I was opting for OCZ due to the spectacular prices compared to Kingston and Corsair, but I never looked at others such as Crucial.

Supported memory and Qualified Vendors Lists frustrate me too.... In many builds I have looked but never bought QVL ram... Never had a problem

The "supported memory" list is just a listing of products that they were able to test and confirm worked. It is a tiny subset of the memory that will actually work in the board.

In general, the RAM compatibility issues that people experience with modern RAM (assuming they are buying the correct type, ie not trying to put DDR in a DDR2 motherboard) are usually related to voltage. Occasionally, memory that wants to be run at a higher voltage than the motherboard supports will create problems.

There's no need to limit yourself to the motherboard maker's list, unless you just need additional assurance that it will work.

Take it with a grain of salt since some vendors will change the PC board and ICs, which can dramatically affect compatibility. For best performance, stick with quality JEDEC 1.8V DDR2 667 or 800 RAMs from Crucial or Kingston (N5 series). These should be able to run at rated speed with 1.8Vdimm and 4-4-4-12-2T timing. Bumping Vdimm to 2.0 or 2.1 should yield at least another 12% more speed.

I've never looked at qualified memory list and never had issues with any memory I've used. Knock on wood.
