Stable @ 3.8! I will post screenies when I get home, as I am at school till 12 then I have work till 10

Yeah... That is a little too high for my liking.

I have it running 3.8 with 1.6, which is more reasonable. Now I have to test what the minimum vcore for 3.8 is. I want to get it to at least 3.9.... but if that is not feasable I will keep it at 3.8.

I have tried some of the higher busses, (500x8, 550x7)but this board is just not happy with lower multis and higher bus like Intel-based boards are. Trade off for SLI I guess..

Wow! That's an awesome overclock man! Good job!

Two loops is EXTREMELY inefficent. Would would get much better performance by just adding another radiator to your current loop. If you need more water flux then just use a more powerful pump (the Eheim 1250 is silent and very powerful)

Zelda, I already have the most powerful single pump solution out there aside from the Iwaki RD30, and have already added another rad to my loop, and there are guys I've seen with noticeably better temps than me who are running separate loops to the CPU and graphics.

I don't think it's "inefficient" if you do it right; I'm not sure where you're getting that. Obviously, a CPU is going to heat up a lot less if you're not passing the water over two hot G80's before routing it back to it--not to mention adding all that extra tubing and restriction with two GPU blocks.

When I first constructed my loop I tested it before plugging in either of my GTX's. Temps on the processor were a good 7-8C lower than they are with them in my loop--and that's on all that additional tubing and restriction from the graphics blocks that wouldn't be there if I had the CPU on a single, short loop. That's a significant difference--especially when you begin pushing enough voltage to the processor to hit Intel's advisable stopping point for temps.

buffbiff also says above that the G80s added 6C to his temps. You just can't rid your loop of that extra heat/restriction/tubing.. no matter how strong a pump or radiator you have. Two loops is always going to get you better temps as long as you don't skimp on the parts.

I don't mind fans really and water cooling is a bit messy if you want to change something out...

Nice O/C though, I mean its at 4GHz and your within windows, thats good enough. Probably don't mean to much but I'd assume with that type of O/C if you could run 3dmark06 you could get a really nice score.
