I'm glad I found this...I'm almost finished building a system with the DFI X58 UT board and a W3520...My memory is not as good though (G.Skill DDR3-2000 8-8-8) and I'm using a 4870x2 as well...at least I have a guide now. Good work as always Eva...4.4ghz with 1.08 vcore is amazing...and temps seem to be under control too. What kind of cooling did you use here? I have a Xigmatek Thor's Hammer but am too lazy to rip it out of my fully functional C0 i7 system...for now I'm gonna use a Xigmatek Dark Knight with the proper back plate and screws. Hopefully it will hold up well. I remember you mentioning in a previous thread that putting a fan on the heatsinks for the digital phase power was important so I got one of those Antec spot fans just for this.
