Hey guys, I just recently completed my high performance gaming PC and am now looking into overclocking and getting everything stable, etc.. and I need help.

I have never done this before, so I'm a complete noob at it, and I got several questions, and am looking for the best advice I can possibly get from any and everyone.

After some good research I've seen that these chips (3930k) can acquire some pretty high and stable overclocks (4.6-5.0ghz) and I'm wanting to do this myself, if I can figure out how. I'm not quite sure of everything, or if I'm doing it right, but at this moment, I have came across this current video:

http://www.youtube.com/watch?v=cdypzNu4He0

I have copied his bios by manually entering everything I could tell that I had different, and I'm wanting to know what I could do, or if I did everything right and should leave it as is..

My specs are as follows:

CPU: 3930k
GPU: 2-WAY SLI Titans
MB: ASUS Rampage IV Extreme
RAM: 32 GB 1600 CAS 7 Gskill Memory

Right now from copying his bios I have it running at 4.7ghz, at 1.392 Core Voltage.
I ran intel burn master on the highest setting and it said that I passed.
I also ran prime 95, and it passed.

My current temps are around 40-45 stock, and was ranging anywhere from 70-78 on full load when running these temps. I'm not sure if these are safe, if I should keep what I got, or approach another route.. being that I'm completely new at this I could use all the advice I can get.

For cooling I'm using custom water cooling, 2 separate loops. The loop cooling the CPU/MB is a modded h80i radiator with push/pull fans.

For the gpus I got a 240 radiator. I haven't overclocked the titans yet, but I want to as soon as I finish and find out what I should do with my current CPU situation.

I have some pretty crappy 1500 RPM fans I'm using on the radiators, but I just ordered some of the corsair high edition 2350 rpm fans, and will be using those as soon as I get them.

Look forward to some advice/help.

Thanks guys.
 
Those temps are safe.
You really need to worry when they get higher into 80s at 90 is where it should shut down your PC.

We actually have the same CPU and MOBO.
That guy in the youtube is doing it wrong.
I have a stable 4.7GHz OC.

What I'd suggest is going back into BIOS go to the EXIT and restore safe defaults.
Then select the "Load Gamers OC Profile".
Drop down to "Turbo Ratio" Select "Per Core".
You'll see boxes open up.
In each one enter 47 since if you're following his guide you're not getting true 47GHz OC.
Right now you'll mostly get 4.4GHz OC.
Make sure after you enter 47 in each block you hit enter or it won't be saved.

Near bottom you'll see "CPU Performance Settings" click it you'll see "Enhanced Intel SpeedStep Tech" if it's not Enabled do it.

Go back to the main screen (Extreme Tweaker) go down to BCLK Skew make it Auto if it isn't.

VCore will be set at 1.400V automatically. Start there.
Leave all the other voltage settings at Auto.

Next go to Advanced Tab. Then select "CPU Config".
Make sure "Hyper Threading" is Enabled.
You can Disable it if you want to try for the lowest temps but you'll not see any real difference.

Next (same screen) scroll down to "CPU Power Management Config"
Make sure "Enhanced Intel SpeedStep Tech" is also Enabled.
(Same screen) Disable the following: CPU C3 > CPU C6 > CPU C7.

That's it now Exit and SAVE.

This is where you will run (I recommend) Intel BurnIn Test.
And a great temp program Core Temp. In the Core Temp settings enable "Start Core Temp with Windows"

Start the burn in test but make sure nothing but Core Temp and Intel BurnIN Test are running.
For the burn in I'd set it to 3 or 4 "Times to Run" you're only seeing at this time if the volts are enough for stable you can do heavy stress testing later.

If doesn't BSOD happens you can go back into BIOS and reduce the VCore by 0.05V and redo the test if you do get a BSOD put it up/back up 0.05V highly avoid going to 1.500V that will degrade your CPU fast.

Once does you'll have a stable and true 4.7GHz over clock.

I personally never go above 54C with my OC but I have a custom single loops for my two 680 GPU and CPU. With Stress testing it tops out at 71C. Just remember when stress testing all cores are heating up but it's not very common to have them all at 100% for long periods of time so as long as the temps do go near 90C you'll be fine.

Thanks for the detailed reply, I'm doing just as you said and doing great! Going to start lowering the vcore as you suggested to possibly get lower temps once I my SP 120 high per fans get here. I'm assuming this will also work if trying to get a higher overclock, just change the 47 to whichever. This is pretty simple and allows me to have my system stable at this overclock, thanks again man!
 
Anytime.

Nice thing with this board is you can do a bad OC but the MOBO has special protections so you can never ruin it.

Just remember never go to 1.500V stay below it. Unless you got a stock pile of CPU's.

Just curious tho, what are your temps on full load with this overclock? As I said before I got around 40-45 with idle, and 70-78 or so with full load running prime 95.
 
Just browsing the internet for the last hour (won't raise temps really) I'm sitting at 36C on the hottest core lowest core is 27C.
During stress test it caps out at 71C.

Just mind you the water cooling loop I have I went for the best at the time.
 
I forgot something that will help temps a bit.

First off go to Start then Control panel.
Go to Power Options.
Click on "Change Settings" on your preferred power plan.
Then click on "Change Advanced Power Settings".
A new window will show. Scroll down to "Processor Power Management".
There change the "Minimum Processor State" to 0%.
Click Apply and OK.

What this will do is when you're not doing something that needs the CPU power with it's OC it will power it down. In turn your temps will be a little lower. This is what the "Intel SpeedStep Tech" is for.

Yeah I was looking for an awesome loop myself, the original plan was just for the h80i modded radiator to cool the cpu itself.. but then I threw in the MB block, and now its cooling both the MB and the cpu, and I think that may explain a little higher temps opposed to just cooling the cpu. That's why I'm hoping the new fans will decrease the temps a bit, as well as when I start doing the absolute lowest voltage testing for this OC.

Once I do that I'll see at what temps im looking at. Hopefully it'll be fine. If you got 71 and I'm looking at around 70-78 fluctuating I only gotta get it a little lower and should be fine.

I do have the speedstep enabled as you said in you instructions, does this combine with what you previously said? Or do you have to enable/disable one or another.
 
One is for the BIOS, my first post here, the second is to take it a bit farther within Windows OS.

I have two radiators. A 360 and a 240 with a total of 10 fan (Gentle Typhoons).
But I'm cooling 2 680 GPU OC and a CPU OC.

I love my water cooling but I just finished my spring cleaning and planning on switching to a Noctua D-14 soon. Once I get the money for the air cooler I'm going to sell off my loop.
Just have a hard time doing the cleaning since I'm disabled with bad back problems.
Already got my spare parts on Amazon.
 
-i have a 3930k at 4.8ghz at 1.42 and i get mid to upper 60c depending on the temp in my house on my water loop when i used to run a chiller at 60f i would get upper 50c load temps

You could always get better temps just requires more or better cooling equipment.
My APT is hot as hell since my neighbors like to keep heat full blast nearly year round that I actually have my windows open in January.

Makes me wonder if I buy an AC I'll get lower temps...
 
For people using this chip and overclocking, or even not overclocking.. are you guys using the speedstep and clock down stuff, or are you guys letting your chip sit at the overclocked speed?

For example.. if you got it at stock 3.2, are you letting it just sit at 3.2 all the time, or do you got the speed step turned on to clock down when not being used?
