[NWH] Corsair Dominator 1866C8 TEC - Peltier-cooled memories

Product
The kit we have had the chance of evaluating is an engineering sample, as shown by the pictures. Corsair has informed us that the design is not final and we assume that when this product becomes available it will look more like Dominator GT, which is a new line of products. A circuit board for keeping track of memory circuit temperatures is also something that will complete the product. The solution with the water block is more than OK and you can cool everything from 2 to 6 memory modules with the same water block. You don't have to break the water loop to install more memories, which is of course an advantage when you have a system connected and leak tested. If you think the Peltier is too much you can simply remove and just use the water block.



Performance
The performance is highly satisfactory and the modules lives up to the specifications and more, and if you increase the memory voltage you can push them quite a lot higher. The memories are specified to 1866C8 and our overclocking tests shows that it is possible to reach as high as DDR2100 at the same settings and even higher with looser timings. The water block is proportional for handling both Peltier and the modules. The additional performance the Peltier enables isn't great, but the lower temperatures could be more useful with a closed system.



Conclusion
Corsair has presented an innovative solution for cooling memories way below room temperature using water cooling and Peltier. The solution is flexible and can be used with a number of Corsair's new memory circuits and with everything from 2 to 6 modules. During our tests we haven't been able to register any kind of overwhelming improvements with the Peltier element, but then again it's not necessary to activate it, which is just another sign for flexibility. The memories have good margins for overclocking and responds well to higher voltages. From a larger perspective you realize that you only need water block for the processor and possibly graphics card for a water-cooled system. This system is also very easy to install without any major modifications needed. We have no information regarding the price, but we can't imagine it will be cheap.



Pros
+ Overclocking potential
+ Flexible water block
+ Water cooling easy to use

Cons
- No substantial improvement with Peltier

wow and I thought fans on top of ram were overkill

They are starting to stick pelteirs on a lot of things now. Why not memory? Only problem is you are not supposed to raise the voltages to terribly high on i7 ultra performance boards anyway... but some people are willing to risk it.

wow, it actually decreases errors
sweet

didnt expect it to have much effect on mere RAM at all.
