Dominator or XMS3 for i7 build?
I am piecing together an i7 920 build and am a bit puzzled by the current lineup of Corsair's memory. I am interested in 1600MHz but Corsair's product lineup has the lowest CAS memory for that type as XMS3. I thought that the DOMINATOR line was the high performance memory. At stock, the XMS3 looks to be better performing. Would I be giving up any significant overhead room by going with the "mainstream" XMS3 vs the high performance DOMINATOR series? I'm just wondering what the trade offs are beyond the obvious timing specs.

TR3X6G1600C7 7-7-7-20. 1.65V XMS3

TR3X6G1600C8D 8-8-8-24. 1.65V DOMINATOR

With a I920 the difference would be hardly noticeable and in fact some I920 CPU's will not over clock to get the memory at DDR1600. I920 CPU's are rated at DDR1066 for the memory you know that right?

In my opinion I would go with the Dominator as they are just so more aggressive! I don't know about the price difference but C7 vs C8 at the 1600Mhz wont make too much of a difference, plus you have so much more options for upgrades that you can add to the Dominator series.

Either of these will be a great part for that system and I would agree if you can go for the Dominator parts they are a bit faster and will be more versitile.

Please let us know what you decide!

Same Here..
I'm Looking at the same memory. But what is the real difference between the Dominator and XMS3 besides the heatsinks, and the Latencies. If I want to overclock my RAM and CPU is Dominator really more capable? If so Why?

Yep, those are the differences. Why go for the Dominator series? Better dissipation of heat with a heat spreader, which could result in better OCing. No guarantees in OCing of course :)

Thanks for the reply. I'm probably making things more complicated than they are. Now my issue is the price..I know I can get other ram which can OC just as easy and is half the price. I Have always been a fan of Corsair, and I hear they are just the best. Guess you have to pay for the

I just saw this thread, which is similar to my own. In fact I should have added on to your thread instead of starting my own.

Based on the fact no-one has provided solid reasons for choosing the Dominators, I would pick the XMS3 modules instead (which I've just purchased). Of course visually the Dominators look great with their large heat spreader, but does a Dominator RAM module really overclock and get that much hotter than an XMS3 module? I'm not an expert but to take a guess, I'd say not. The large heat spreader the Dominator wears smacks of marketing targeted to the enthusiast crowd, to me at least.

For myself the XMS3 modules have more "Pro's"; they are CL7, low-profile and are cheaper than the Dominators, three good reasons why I bought them.

If you are going to leave the settings at the ones which we test and guarantee then either module will work just fine. If you are looking to overclock, the DHX2 heat spreader on the Dominator modules will keep the memory cooler and give you better overclocking results than a standard XMS part.
