Lots of folks have been raving about this new CH-UTT memory. Though it is very power hungry, we have seen that you can still pull off very workable speeds even on motherboards that don't have the outrageous VDIMM options. Running at 2.8v with no active cooling in place still gave us a very solid 20% increase in memory speeds. Given the results I was receiving, I have no doubt that it would go a good deal higher if I had the 3v+ power levels available.
Now you may be thinking that there is no way you could afford memory like this, but you might be surprised. This dual-channel memory kit has a MSRP of US$159 but a quick check online shows it available for as little as $129. This is very reasonable for a 1GB kit of performance minded memory. Oh, you might also be happy to hear that Mushkin offers a lifetime warranty on this memory kit. This warranty is good for those who use up to 2.9v through the modules also, so compare this with the regular modules that are only warranted at 2.5v!
One item of note is for those who may have an OEM system and are looking for a memory upgrade. In this case I would not recommend this kit as it is unlikely you will have the option of raising the VDIMM to a level where these modules will work well. At the standard VDIMM setting of only 2.5v, this memory kit offered no stability even at 200MHz speeds. As long as you can keep voltage levels at a minimum of 2.7v you'll do fine, but the higher the better for these babies.
Bottom line... If you're looking for high-quality memory in a dual channel rig, keep these Mushkin modules toward the top of your shopping list. With solid performance at lower voltages and the ability to handle upwards of 3.5v+, you'll be hard pressed to find better performance for your enthusiast rig.
