I added some new toys to this build this weekend and got some overclocking done.
3930K - C2
Asus P9X79 WS
4x4GB Samsung 30nm ram
Overclocking the 3930K is straightforward and dare-I-say elegant. As clockspeed increase, VID automatically increases so as a user, all you're left to do is manage LLC and a little off-set here and there.
This overclock could not have been possible without Sin0822
and the Asus X79 overclocking guide
First I used the Asus guide to set preliminary power thresholds and such to ensure I'll have all the power I need for a nice overclock. Next, using Sin's explanation of the vcore and vid relationship, I started the process. Initially my goal was to use turbo overclocking and set multipliers for different load thresholds. I canned that idea eventually because Windows makes it very difficult for the highest multi to stick for an extended period of time. I figured I'd just be better off setting all the cores to a single voltage and thereby reduce the complexity of the OC.
I didn't drop turbo overclocking outright, I just set all the cores to the same turbo level. This way I can still enjoy idle down-clocking and the significant power savings it provides.
My VID started at 1.14v stock. Moving up from there I eventually stopped at 4.8Ghz and 1.31v at load running Prime95.
Looking around at some other 3930K overclocks, I think I've definitely come out ahead in the silicon lottery. My goal was 4.5-4.6 for all six cores without having to venture too far past 1.3v and I've definitely accomplished that. I don't feel the need to explore any higher for the moment but the magical 5Ghz threshold is looming ever-so-closely, I know I'll make a stab at it soon to really see just how good this processor is.
As for the case, the EATX board was installed with no drama. Things don't feel cramped at all so I'm pleased with that. Actually the EATX board looks more natural sitting inside the case than my old ATX board did. This build has turned out great. I was worried I'd have to make a substantial cooling upgrade for the 3930K, but thankfully the silicon gods were smiling on me and that won't be necessary. The VRMs do get warm. I measure just under 60C during prime loads from the VRM backplate.
One complaint I have about the positioning of the 200mm fan on this case is it sits a little too low for my tastes. All that air flow from the side fan is only being directed to the bottom half of the motherboard below the first GPU. It also doesn't help the GPU occupies the first PCI-e slot since this is a quad gpu capable board. I may decide to set-up a fan somewhere to blow on the VRMs in the future, but it's not a pressing need.Edited by Johnny Utah - 6/17/12 at 11:52pm
