I have the CAS8 1600 Dominators. If you have this Kit and the RIIE see my thread about rhe BIOS in the Xtreme Bandwith section. It won't run stable on 0403 original BIOS. I flashed mine to 0602 and was able to run 6400 QPI, DDR1600 on the DRAM Freq, 1.64xxx (keyed in 1.64) and mnaually adjusted timings to 8-8-8-24. I have not messed with any other OC settings yet becasue I was fighting a Video issue the last 3 days. It turns out my card was defective and needs to be RMA'd.

Those settings seem much more stable with the new BIOS. Before my RIIE would not boot after setting the above advertised specs into the BIOS. It would only run at BIOS deafaults of 1333. Now it runs smoothly, stable, and as advertised. I highly recommend flashing your BIOS for complete memory support if you are using the RIIE.

I also measured and verified DRAM voltage through ProbeIt and got a 1.639v actual reading on the DMM. These are safe advertised settings. The 6400 QPI is advertised for the Extreme i7 965.

Just passing on my findings on this particular RAM, and the BIOS issue I found. Thought it would help. The Dominators are really good modules. I can't wait to tweak them and start OC'ing when I get my Video Card RMA taken care of.
I have basically the same setup as you, just using Core i7 940 instead of 965. Same Dominator sticks. I was able to run them at 1800MHz 7-7-7-20 stable with 1.65V and 1.437V QPI/DRAM. However, I have also noticed that upping the core speed will affect your ability to run the ram so high. I am still investigating this issue...

I am using the newest 0705 BIOS btw.

the review isnt out yet but the cooler seems as a choice for those going watercooling.
Unfortunately, that one is not licensed for sale in North America, and who knows when it will become available. I wanted it as well, even contacted the manufacturer but they said no dice. Maybe I will pick it up in Europe when I go this coming summer depending on what the reviews say.

Oh, and in terms of the watercooling components, I looked at the reviews for the components that come as part of that kit I mentioned, and they are very decent. Most of those components are listed even on this site as some of the best to buy. The only two things I would like different than in the kit is a bigger rad (3 vs. 2) and maybe a voltage adjustable pump. Building the same kit myself is stupendously expensive considering I can buy the whole kit for $290.
