New Computer (First Build) Blue Screen

[Narong]

Hello all.
 
I recently built a new computer (my first build) and everything -seems- to work fine, under normal use. Whenever I try to stress test it, however, I get the blue screen error just after a few minutes. None of my components are overclocked in anyway and the temperatures don't seem that bad, to me. (Core 1 reached 75 deg)
 
At first, I thought it may have been a faulty PSU not supplying enough power, but even after replacing the PSU, I still get the crashes. Also note that I've tried stress testing with both, each GPU individually and without a GPU, but the problem persists.
 
Can anyone help me figure out what's wrong?

 

Component List:

• Motherboard: ASUS Maximus VII Hero
• CPU: Intel Core i7 4790k
• CPU Cooler: Corsair H100i
• RAM: Corsair Dominator Platinum (2x8GB) 1600MHz C7
• SSD: Samsung 840 Pro 256gb
• GPU: ASUS GTX780TI-DC2OC (x2)
• PSU: EVGA SuperNOVA 1000 P2

Is your cooler mounted properly

[Narong]

I believe so. There's no wiggle and during idle, none of the cores reach 40 deg.

Should have it BSOD again and note what it displays. May have useful information.

[Trik'Stari]

What are you stress testing it with? What program?

The error it gives is Whea_Uncorrectable_Error (Or something like that. I don't remember exactly)

I've tried with Prime95 and Aida64 Extreme.

@Narong

Your problem is that your voltage is on adaptive, it needs to be set to MANUAL before stress testing of any sort.

Supposedly Prime85 isn't good for Haswell cpu's like yours. I ran it on mine for about a half hour with no problems though.

Check the read-out your motherboard posts on the Q-Code LED at the time of blue screen, and compare with the Asus manual. That may well help you narrow down the culprit (it has done so for me before). You might also want to do some memory specific tests, and I've had RAM screw me over like that before.

Currently it is set to auto, since I haven't made any attempts to overclock it -- I don't know enough about that yet. If I change that to manual, should I just input the voltage it currently has?

Yup, keep everything the same, just set the voltage to manual and keep the same value.  Run Prime95 again and let us know what your temperatures are and if you crash.

Ok.. That made things worse. Or maybe I'm not changing the right settings? I changed the "CPU Core Voltage" from Auto to Manual and that gave me a the "CPU Core Voltage Override" field. I typed in the voltage it's displaying for Auto (1.088). Tried to boot into OS but it stalls or just restarts at the Window splash screen after about half a spin of the loading spinner.

I think that might be too low of a voltage for the 4790k.  Remember, this chip boosts up to 4.4Ghz at stock.  I think it should be closer to 1.2v, anyone with this chip able to comment on the stock maximum voltage?  Let me look online to see if I can find it.

@Narong

 

It seems to vary.  I have seen between 1.190 all the way up to 1.273. 

 

Lets not forget what we are doing.  Your computer is perfectly fine as is, and the only time you blue screen is when you stress test.  If you don't plan to overclock, then leave your system as is and revert your voltage back to adaptive.

 

You could also manually tune in the stock settings which should give you better temperatures.  Do this by setting voltage to manual and 1.25v.  If it is not stable, keep increasing by .025v until stability is found.  If it is stable, decrease by .025v until stability is lost.  Run Prime95, select Custom, the only value you change is Time to Run Each Test, change it from 15 to 3.  Run for a maximum of 20minutes.  Once you have found a stable result, remember the voltage that worked, revert that voltage back to adaptive and run programs as you normally would.

 

If you do want to overclock, then here are some guides to follow:

Here is a good intro to all of the terminology of Asus Motherboards

I would take nearly every voltage setting off auto (except SA & I/O), try out these specs:

 

Turbo Mode = Off
Core mult = x39
Uncore mult= x39
CPU Ratio Mode = Set all cores = (NOT dynamic)
Core V = 1.25
Uncore V = 1.21
VCCIN = 1.83v
CPU Core Voltage Offset Mode = manual (may also say +/-, choose +)
CPU Core Voltage Offset = 0v (may auto set to +.001)
^^Same for Ring/Cache (same thing ring=cache)
Double check your RAM's recommended voltage and make sure it is manually set to that voltage (probably 1.5 or 1.65v), also check to make sure that the correct XMP timings are enabled. I've had a couple boards undervolt my manual settings by ~.005, if that happens just bump it up accordingly.
Set LLC to level 4 or 5 (LLC is on a different sub-menu, I forget exactly where it is but you should find it somewhere within the advanced voltage settings)

 

Do not use Prime95 for testing, use AIDA64. If you're still getting BSOD's you're going to need to run Memtest86+ to make sure that the RAM isn't the problem. With those settings you should be able to get a stable OC easily with temps in the 65-75C range under load (depending on your cooling and TIM). Once you've confirmed AIDA64 can run for 15-20min at stock multipliers just bump them up x1-2 per run, you'll probably max around 4.3-4.5Ghz.. Those are the standard voltage/mult settings I've used for 4.5Ghz 1:1 runs on 3 chips, 2 failed, one needed more voltage the other needed to downclock uncore.

 

Max recommended voltages are Core/Uncore 1.3v, VCCIN 1.9v. Although I would strongly rec. not going over 1.875v for VCCIN and not over 1.28v on uncore, the uncore voltage can get things very hot very fast. VCCIN will tend to be undervolted in realized values when you're looking at monitoring software, you may need to bump it up in the BIOS by .02-.05v to get it where you want it.

@Faceman

I appreciate the help. You're right about reverting. I was actually thinking of just going back to the defaults and leaving it at that, at least until I gain better knowledge of overclocking. The computer does run fine and I haven't experienced any crashes, even with hours of continuous gameplay with simultaneous recording. Just wish it could be stable during stress testing, too. Thanks again!

Thanks to everyone else, too.

You'll get there bud, everyone has to start somewhere.  Overclocking is daunting at first, but once you understand the terminology and the basics, the "picture" begins to form and you get it.  Its actually quite addictive trying to push your CPU further going for a higher benchmark score or that last little bit of performance.  When you're ready, come back and there will be lots of people willing to help you OC.
