i7 5820k + asrock x99x fatal1ty killer

post #1 of 11
Thread Starter 
Hey there!
Would you please help me finding the right way for OC?

Id like to have 4GHz, what should work with an air cooler.

System:
CPU: Intel i7 5820k
Cooler: Thermalright True Spirit 140 Power
Board: ASROCK x99x fatal1ty killer
RAM: 32GB DDR4 Corsair 2666Hz
GPU: Nvidia GForce 780GTX

1stly ive tryed ASROCK-internal OC-settings for 4GHz. Ran but using PRIME95 CPU >100°C ... thats not good biggrin.gif.
Trying 4Ghz manualy directly brings blue screens (wrong settings for sure).

Actually the system runs stable @3,8 GHz (Prime95 = 65°C). Using multiplicator 38 and VOffset -0,040v. But i dont realy understand that all.
Please tell me in what configuration steps ill find the right way.

There is:
Cpu i/o voltage
Cpu input voltage modus
Cpu additional vcore voltage offset
Cpu input voltage (auto or fix)
Cpu voltage offset

Too much - driving me crazy biggrin.gif

Well, you've learned to avoid software OC utilities, which is a good lesson. However...

A 4GHz OC on a 5820K should be as simple as setting the multiplier at 40 and the voltage at auto. Leave everything else at auto or where it is by default.

At that frequency, I strongly doubt you even need to worry about manual voltage control, load line calibration, etc. unless you get really, really, unlucky in the silicon lottery. Heat shouldn't be an issue even with voltage at auto since you have a decent board.

Would it be better to fine-tune the OC? Yes. Do you need a fine tuned OC at 4GHz? I very much doubt it.

My 5820K can be set at a significantly higher clockspeed without messing with anything other than the above settings. You are only changing the clock by a few hundred MHz.

Your results may vary. I'm sure others can give you more specific settings if you want (currently at work and away from my settings), but I'm thinking you will be fine with just the few changes above.

Thank you.
No- changing just the freq let me have a bluescreen in seconds!
I´ve got it now with a voltage of 1.030V @4GHz.
30 minutes PRIME95 was stable, but at 80°C - do you think thats okay?

Here is a screenshot from messuring:

80C is too high for my comfort - and not something you should have to deal with at those clocks with any decent aftermarket cooler. At 4GHz, mine will only load in the 50s with an H60 with the fan manually set as low as possible via a fan controller. I think you are way too hot with your cooler. What are your load temps @stock?

Your voltage is quite low which may explain your BSODs. Most people need to pump in a bit more to get that frequency, but you are still on the low end of an average 5820k's potential. It looks like people are running theirs to nearly 1.4V+ for the highest OCs, so you can put in more volts without worrying about damaging the chip. Maybe try 1.15V and see how you make out stability wise, and work your way down from there if you can. So, my guess is low voltage being the main cause of stability issues. You are actually pushing lower than the default voltage @ stock clocks, as best I can tell. Are you doing anything with load line calibration? That helps to prevent voltage drops (VDroop) which can cause crashes when overclocking a chip.

Regarding heat: doesn't make sense to me. I am putting in somewhere in the 1.25 range for my 4.4 5820K (I've forgotten the exact number, and am away from the PC) and my heat is nowhere near your levels. I'm running a push-pull H60 with undervolted fans, so I don't think my cooling potential is too far beyond yours. I'd like to see temps @stock for sure. That might indicate a thermal paste issue or similar.

Load temps @stock means without utilization?
Then im on 30°C per core.

Otherwise- maybe you missunerstood me.
Without PRIME95 (what means the cpu is bored) i have 30°C
When i use PRIME95 i have a load temp about 80°C


Sorry, my english is not the best.
You mean my cooler is not the best, didn´t you?
Too bad, because i asked many people what i have to buy best for OC this CPU.

Or is it the thermal paste. It was a "normal" white one.

Lets talk about the other things:
What is load line calibration? (im doing nothing with it)
Low voltage: I thought it would be the best for temperature to decrease the voltage as much as possible? And my system seems to be stable with this configuration?

Here is the product site for my cooler:
http://www.thermalright.de/kuehler/34/true-spirit-140-power

Thank you fol helping.
Ill increase the voltage now ... and tell you what are the results.
But as i understand - the cooling is my issue?
Or are higher temperatures okay, while they´re just there when using PRIM95-Tests?

I mean load temperatures without an overclock. How your processor and motherboard was when you got it. The temperatures under load without an overclock would be helpful. Prime95 is fine to check those temperatures as well.

Your cooler is fine, but not the best. I would say mine is similar. They are both perfectly adequate for overclocking.

Load Line Calibration is a setting in your BIOS which compensates for VDroop. VDroop is when a processor has its voltage change under load, and a temporary drop below the expected voltage occurs. Because the processor doesn't get enough power for a short time, it can cause a crash when overclocking. Load Line Calibration compensates for this effect. There are different levels depending on how high your overclock/voltage is.

You are correct in thinking lower voltage generally means less heat, but you still need to give it enough voltage to be stable. I think you are really close to instability with the voltage you mentioned.

Regarding heat and thermal paste, I am wondering if thermal paste is not applied well to cooler. Your temperatures are above what I expect for those voltages and that cooler. This is why I would like to see temperatures without an overclock to see if there is a heat problem without your overclock. If there is, we can solve that and then go back to overclocking. If there is no heat problem at stock clocks, we know that there is a BIOS setting causing trouble.

Lastly, Prime95 gives unrealistically high temperatures, even as a stress test. I prefer not to use it, as it can make the CPU draw too much voltage and potentially cause damage in rare cases. I like testing my overclocks with more real world scenarios like repeated runs with Cinebench and HyperPi. There are also other dedicated stability testing programs you can use. However, if your CPU is stable in Prime95, it will probably be stable in everything else. Temps in Prime95 will also probably be a few degrees hotter than what you would experience in normal use as well. Again, my favorite "real-world" test is Cinebench. I've found it is pretty good for detecting instability, and it also shows around what the max temps you can expect in gaming and encoding to be. Prime95 will be hotter than your CPU will EVER get in real use.

Ahh okay.
Under normal conditions (3,3 GHz) @PRIME95 i have 60°C - i think that is a normal value?

Ill attach the messuring result (no OC):
http://www.pasteall.org/pic/show.php?id=105487

I know prime95 is very extreme. Under normal conditions (simulating some fluids in example) i never had continous 100% load on the cores.
But its good to check what would happen- just to be sure wink.gif.

I think this VDROP could be the "offset" setting i found in my bios?
I could add some bios photos:
CPU config: http://www.pasteall.org/pic/show.php?id=105488
FIVR config: http://www.pasteall.org/pic/show.php?id=105489
VOLT config: http://www.pasteall.org/pic/show.php?id=105490

Sometimes you can choose between AUTO / ADEPTIV / OFFSET / OVERWRITE

Check your voltage during the test with CPU-Z to make sure you are actually getting the voltage you expect. If so, I'm starting to think your cooler just may not be up to it. That, or there is a setting in the BIOS that is pushing more voltage than 1.15, and if you check CPU-Z, it should reveal if that is true or not.

CPU-Z gives me the same voltage wink.gif.
I´ve tryed 4.2 Ghz with 1.055v ... while prime95 ran up to 75°C and crashed after 2 minutes i´ve tested an other program.
Same CPU-settings with RealBench gives me around 70°C (continuos) and no crash in 15 minutes.
Working in my 3D software gives me no crashes, cpu under 60°C while simulating etc. Thats okay?

Do you think i should replace the cooler?
Do you think other thermal paste and a 2nd cpu cooler would worst it?

Changing the clock + vcore is the right way for OC? Or should i try other things?

Thank you!
