So when I went with my new PC, I went conservative, even with DSO's rock solid support.  One of the reasons was also because I chose to stay with the stock cooler (yeah i know, bonehead move).

I am about to install a Noctua NH-D14 and would like to go with a half-decent overclock.

i7-930 using Noctua NH-D14
Mushkin Blackline 1600
eVGA X58 SLI LE
(On the subject of cooling, I am also in a Raven 2 case)


Ive read the guide on overclock.net and some of the threads here (including the useful threads sticky).  My preference would be about 3.8GHz but I do a lot of CUDA enabled calculations and stability is absolutely key.  Is this reasonable with these parts?

Bonus for a link to a thread targetting this speed with a similar config.

alright, lets start at the begining
you will need
 
prime 95 (Windows 64-bit: Download about 3/4s down  http://www.mersenne.org/freesoft/ )
 
then go in to your bios and disable turbo mode, should be under advanced options or something.
go in to windows, open up 2 cpuzs, screenshot the main and memory tabs
post that screenshot
then open up realtemps and prime95, MAKE SURE YOU DISABLED TURBO run a blend test for about 10-15 min and then screenshot your realtemps window 
 
 
go in to your bios
DO NOT USE THESE SETTINGS just plug in what your numbers are instead of the red ones

ahhh, went with the stock cooler like me eh? had it overclocked too and freaked out at the 65C idle temp? lol. yep, upgrading that cooler's a smart move.

as for stability, if the overclock can handle a 24-hour blend on prime95, according to most people, it should be perfectly fine, since prime95 taxes the cpu far beyond normal usage and you won't be using it for more than the tested stable time, eh?

oh, and if anyone can answer this, on the topic of disabling turbo, would killing off c-state be a good idea too? disabling it before seems to have leveled my clock pretty well at the overclocked speed on past occasions, since it dipped sometimes when it was on.

c states are best left off for complete stability

From a cooling versus performance perspective, is there a preferred methodology of getting to 3.8GHz?

200 bclock with a 19 multiplier
vs
190 bclock with a 20 multiplier
vs
181 bclock with a 21 multiplier

cant know that until we know what your setup can handle, the higher blck the better, but with that comes more stress and higher temps.
 
one of the many points of all that i gave you to do

So tinkered with my overclocking into the wee hours of the morning. The NH-D14 dropped my idle temps almost 10 degrees over the stock cooling before overclock.

I ended up pushing my overclock to a mild 3.6GHz as that was the sweet spot temperature and voltage wise before I started having to push a little harder. I have to say I was not very impressed with my little 930, it required more voltage than I thought it should to get to 3.8.

Running my 930 at 3.6, I still have Prime95 going but it hasn't gone beyond 68C under my NH-D14 for any of the cores.

I am actually underclocking my RAM a little bit, which I am entirely ok with, for my uses rock solid stability and a safe margin on the temps is far more important to me than being able to forum ninja a 4.1GHz overclock on air.

So...
i7-930 on a eVGA X58 3X (the new 767 part, more on that in a minute)
Running 20x180 @ 1.285V for 3600MHz nominal
Under an NH-D14 monster cooler
6GB Tri-Channel Mushkin @ 2:8 for 1440 Nominal

At the time of this writing I am at 26 hours of Prime95 burn in preceded by 20 runs of Linx and my max temp on any core has been 69, and that was a spike. Cores run 41-45 degrees during normal 2d productivity operations and hover in the mid 60s under extended 100% load.



So the new eVGA motherboard.
1) They are harnessing a piece of the PCI express bandwidth to do the USB3 and SATA6gbps. Thus you are 16/8/8 under the best of conditions. I knew that going into it and am ok with that but for others that may not be ok, it bears repeating.

2) As with most eVGA hardware, its a great setup, lots of accessories in the box. I wish there was one more USB header (only two on the board, accessible), maybe instead of the two firewire headers. I would much rather have 3 USB and 1 1394 than the 2 and 2 it has now.

3) As of this writing, when you register the board to your account over there, it really doesnt get you anything. The new -767 part is not listed in any of the support listings so you cant even GET to a support page for drivers and such. AND even when its registered to your evga.com profile via the serial number, it is not recognized as a registered X58 motherboard part so you don't get access to e-leet. I had to do all of my overclock work via BIOS which made it take that much longer. It may sound like a little thing but when you release a part, I am one of those that thinks your marketing and support channels need to be ready to appropriately support it.

4) The BIOS was a little odd. Out of the box, the boot order is hard drive before CDROM. There is no auto-detection setting for CPU fan between voltage or 4 pin intelligent fans. With everything on the default settings and auto-everything, it detected my 2.8GHz i7-930 as such... and then ran it at 2.66GHz (?!) and underclocked my 1600MHz Mushkin blackline rated for 7-8-7-20 to 1066 8-8-8-something.

I think with those temps you can easily run 3.8 GHz if you want to and likely approach 4Ghz.
