5820k I need an Overclock Assist

[Midian777]

So this will be my first time overclocking a CPU as I haven't ever really had a need, and I may it even have a need now but I figured I would post it to the experts and get some feedback.

I recently bought a better build from new egg and though I am waiting for the parts to arrive I want to know how to do this before I get carried away and break something. I am going to be over clocking the 5820k to about 4 Ghz, I dont really need anymore than that and I am running a Gigabyte gaming G1 wifi motherboard, ddr 4 ripjaws 4, the 5820k, and a corsair h100i AIO for the cooling. I think 4 Ghz should be fairly attainable based on what I know of Haswell CPUs.

I know I need to get into the BIOs and change the multiplier to 40, and I am thinking the voltage to 1.15 as a starting point. Do i need to mess with anything else, I don't need to overclock the RAM as DDR4 is gonna scream right out of the box. Does anyone have any feedback or thoughts on this. any feedback would be appreciated.

Look at guides eg http://www.anandtech.com/show/8426/the-intel-haswell-e-cpu-review-core-i7-5960x-i7-5930k-i7-5820k-tested/3

Hey i7Baby and thank you for the response I have indeed looked at this but I was assuming the octocore might differences from the 6 core (Then again it is a haswell e and the die is the same so their methology would work that same way right?). I also somehow missed the listed voltages they used... wth is wrong with me today lol.

It's more of a method than looking for "magic voltages and clock speeds". Every CPU is a little different, so start with little jumps, test stability, watch temps, then go a little more. When it crashes, add a little more voltage. CPU heat/temp will probably decide how far you can go, unless you have a massive heatsink/radiator.

Not massive but it is a self contained high end AIO from corsair h100i. Thanks for the reply.

It's the same methodolgy for any cpu in the series.

i just built a 5820k rig, i used an x99 deluxe motherboard from asus. they have a 5 way optimization software that came with the board that does a one click overclock and I got it up to 4.3 ghz with that method. it was soo easy it was too easy. i might tinker wth the voltages a little manually to try to get to 4.4 or 4.5.

 

[chodamoyer]

just was able to get it to be stable at 4425 MHz or 4.4ghz with x35 multiplier and 126.4 MHz bus overclock at 1.308 Volts adaptive voltage.

I did this using only asus ai suite overclocker and manually told it to shoot for a voltage of 1.309 V and also slected bclck (base clock) overclock. it did the rest.

I think it was actually stable at 4.5 ghz but the way the ai suite software works it backs it off 1 overclock b/c it couldn't get 4.6 ghz to be stable so even thogh 4.5 is stable it uses 4.25 ghz as the setting b/c it has a buffer of 1 multipier or so I understand.

btw this is my first computer I have overclocked b/c none of my other computers were capable of such shenanigins. but I am an expert tinkerer.

 

[chodamoyer]

my temps are like cpu in the high 30's to low 40's deg C on idle it was max like 69 deg c when establishing the overlcok on my nh-d15. which means likely I could go for a little more voltage but I am not going to push it anymore given what jj has said on youtube about 1.3 volts being the safe max.

 

[Froxiilol]

I managed to get my 5820k to 4GHz with 1.200 volt running stable, not getting past 73 degrees on full load. I had a lot of problems with overclocking the cpu without touching the volts tho, got several bluescreens from overclocking to above 3.6 without touching the volts.

I have mine at 4.3Ghz, multiplier alone. I crash using base or voltage modifiers though. I was shooting for 4.5, but I guess +1Ghz on stock is petty good.

 

[Guest]

For some reason i am unable to overclock it past 4 GHz, on a water cooler, even pumping the voltage up to the 1.3V safe limit.

My build is an Intel i7-5820k on an Asus X99-A board with G.Skill DDR4 2666 15-15-15-35 RAM and a Kraken X61 cooler.
After playing around with 5-way overclocking and manual tinkering, I have finally found a simple setting.
With the XMP 2666 RAM, the base clock is at 125, and my multiplier is at 34.
Giving me 4.25GHz at a max temp on my hottest core (core 3) of 68c under max load while Mp4 video encoding.
The voltage sits at a comfortable 1.25v.
Also the low temp allows me to set the Kraken to 70%, which is audibly pleasant.
I hope you are as pleased as I am with my 5820k.
Love always, E

I'm running stable @ 4.5Ghz... 43 multiplier w. 105 bclk... 1.21v... it idles in the 30Cs and maxes at about 75C...

maybe i can get more out of it, but it hangs any time i try 4.6, in whatever combination...

Ya when I was first playing around with the overclocking, 4.5 was my max as well. It also wasn't 100% stable. Sometimes when I would leave it doing harsh number crunching overnight, it would crash a few hours in... 🙁

 

[troublemecca]

It's weird too.... Any time I try a bclkhigher than 105 but less than 125 the system won't even boot...Gets to POST and then shuts off... had to clear cmos a few times before I gave up

 

[TruthPhoenix]

Okay, I decided to change things up a bit. So I dropped the DDR4 speed to 2400mHz (from 2666) which brings the base clock back to 100. And I increased the multiplier for the CPU to ~44.5. I tried 45, but it was a bit toasty for my taste. So I switched the multipliers to "per core". As my hottest cores were 3 and 5, I dropped the multipliers of 3,4,and 5 to 44. But left 1,2,and 6 at 45. The result is a lot cooler for only a loss of 0.5gHz and the voltage is at a comfortable 1.26v.
Luv my 6 core baby, E

I have clocked mine 5820 up to 8625MHz!!! With Asus Ai Suite 3 and its dual processors auto tune...
I just canno believe it, and I wonder is thet some kind of a mistake?
It crashed on 8750MHz, 157%...
Is this clock for real?

I have Asus X99-S, G.Skill 3000MHz 16Gb...

Yeah, I don't think that is right and I'm saying that as I had a similar situation.
I'm running Asus X99-S/5820k, GSkill Ripjaws 2666 32GB and 2x Gigabyte 970 G1's in SLI. I did a bunch of different OC's using the AI Suite.

Using ratio OC it got up to 4.6Ghz before BSOD (stable at 4.5Ghz with memory at 2133 - BCLK @ 100). I played about with this a bit and then decided to try the BCLK OC method. It got to 12Ghz (yes, 12Ghz - 275% increase) before I decided it is BS and cancelled it assuming something wasn't right. Judging by your frequency, it seems that you did the same thing and had BCLK@125 and ratio @70?

WATCH OUT #1:
After using the AI Suite to switch back to Ratio OC only, running ROG Benchmark and being very happy at how easy it was to OC, I saw that the CPU voltage was hovering at 1.4 in AI Suite and just under that in CPU ID! Not good considering the max recommended voltage before damage starts is 1.3V. This is when I just decided to reset the CMOS and manually OC everything having done a bunch more research.

So, my latest settings are:
BCLK: 100
CPU Ratio: 44
CPU Input: 1.9V
Vcore: 1.27V
RAM: 1.35V / 2666Mhz / 14-14-14-34-1T

CPU clock (temps): 4400Mhz (idle: 37C, 10mins @ 100%: 60C (~70C core) in ROG Benchmark)

WATCH OUT #2:
AI Suite reports a higher voltage than you set in the BIOS, or the mobo adds voltage even if you set it manually. I manually set my VCore to 1.272 and CPU ID shows this, but AI Suite shows a VCore of 1.28 @ 1.5Ghz and 1.292 @ 4.5Ghz. This can easily tip you over the 1.3V if you aren't careful. I'm going on the side of caution and trusting the AI Suite (which previously said my VCore was 1.4V using 100x45). I've still got a 29% OC which I'm very happy with.


P.S. If anyone is wondering about the cooling I'm using: CM Storm case + Noctua NH-D14. A very quiet and efficient beast without the hassle of water cooling (been there, done that).

Does anyone have any feedback or thoughts on this. any feedback would be appreciated.

I also just recently (3 weeks ago now) built a new i7-5820k system, quick specs;

Intel i7 - 5820k (AIR-COOLED)
- Cooler Master Hyper 212 EVO (with extra/optional 120mm fan installed)
- Cooler Master HAF 932 (High-Air-Flow case)
ASUS X99 Deluxe
32GB DDR4
GTX 980
Rosewill Photon 1200W PSU

My system has been on and under heavy use for a 8 days at 4.5 Ghz (32% increase from stock) - and it is AIR cooled.
Idle temps are 33-37 Celsius and under load max temps 69-74 Celsius

I do a lot of work with VMs (virtual machines), code-compiling and am a big gamer. This thing is a monster. No hiccups.

This is how I accomplished this (bear with me Ill get to my actual advice here soon 😛)

The X99 mobo comes with some nice Over-clocking software (AI suite as mentioned in previous posts) that will push a full load on the CPU -all the while monitoring temperatures- and gradually step up the base clock RATIO in small increments until hits a max temp, and then it dials it back a notch to a stable overclock
I mention this for two reasons 1 (its awesome) and two; the method that AI 3 uses with auto tune is basically the same way you want to approach a manual overclock
--SMALL increase changes, test, increase, repeat, hit ceiling, dial back a bit, burn in stable--

I obviously did some manually tuning/over-clocking because, well, it's fun
Anyways I found with my testing the BEST (fast AND stable) OCs were achieved by following this method;
1. Pick a maximum Voltages that you feel comfortable pushing to the chip and set it (mine was 1.22V)
2. Leave the BCLK (BUS Speed) at the default 100 Mhz
3. In small increments increase the Ratio/Multiplier (number multiplied by the BCLK to compute CPU clock speed, default is 33) 33 x 100 = 3300 = 3.30 Ghz -(stock speed)
--I made increases of 2 to the Ratio, ran Prime95 for 10 minutes, increase, repeat, ceiling, dial back (47 crashed and 46 was unstable), run prime95 for 6 hours with temp logs running, insure stability-
4. Done

With LIQUID cooling I could see getting close to 5Ghz on this chip. Bear in mind always that every single ship does not behave the same way, -so please anyone don't read this and just go set your multiplier to 45 and hit go - Always monitor temps/fan speeds as you are tuning, whenever possible- Make small steps, and only change one(maybe 2) things at a time!

Hi NerdIT, I have a similar setup and i was hoping you could help me out reach similar results.

My setup is:

Intel i7 5820k
Asus X99-Deluxe
Noctua NH-D14 with 1x120mm 2000rpm IPPC PWM and 1x140mm 2000rpm IPPC PWM
Fractal Design Define R5
32GB DDR4
EVGA GTX980 Ti ACX2.0
EVGA Supernova 850 G2

I have tried different configs with Vcore, FSB, Fans tuning and I am having difficulties to reach a sweet spot between CPU Clock, Voltage and temps.

At 4,5Ghz and a vcore of 1,22v works but the cpu runs hotter than 40c on IDLE. So I have a few questions for you.

Do you use FAN Xpert 3? and if you do, could I see a screenshot of your fans speed?
Do you use fix vcore 1,22v? or is it adaptive? if adaptive, whats your offset vcore and CPU cache voltage value+offset?

Im aware of the cpu die lottery, but according to this site, http://www.overclockers.com/3step-guide-to-overclock-intel-haswell/, my cpu belongs to greater 50th percentile on the Haswell overclocking-ability bell curve.

I dont wanna do crazy oc'ing, it's just that i am not happy with cpu temps. I know that 5820k will run hotter as there are more components packed together. I just wanna reach similar results as you have, being 4Ghz or 4,5Ghz.

Thanks in advance.

Hey there moexius, So before I get into (attempting) helping to answer your questions - I want to make an update on my system - as there was a change.

I woke up to a dead board (x99 Deluxe) 🙁( no happy. I hope this doesn't happen to you but I think your okay -there was a storm the night before and I didn't have it plugged into my surge protector -DERP.
I dropped the chip in my friends board to make sure that it wasn't damaged - (it was fine, ran prime95, aida, cinebench on it etc) , It's pretty hard to "fry" these newer chips nowadays -so i assumed the board but wanted to make sure.

Newegg RMA'd the mobo and I got a ASUS X99-A/USB 3.1 in it's place - as the deluxe was not in stock, and I didn't really need all the super fancy bells and whistles on it.

Although these boards operate identically. So I essentially have the same setup.

Now, getting down to business. On my new mobo, I WAS using AI suite/Fan xpert 3 as before (installed on Windows 8.1 Pro) but started tweaking a bit more. I eventually started having application errors and started getting crashes, freezes, profiles reset a few times -all related to AI Suite.

So I ditched AI suite and do everything through the BIOS/MoBo Hard switches.
You can do all the same things and more just as easily and in BIOS
I like the idea of the mobo handling these things because it is more likely (and has been) to be more stable as it not dependent on a Windows program to stay running perfectly all the time in an imperfect world.

The TPU and XMP switches on the board are super easy and do a moderate over clock of CPU/DRAM -when I switched TPU to the I position it put me about right at 3.9 -4Ghz. It gets no easier than that.!

**DISCLAIMER**
Anything in BIOS concerning voltages with DRAM/CPU - unless you really have a FULL understanding of Electrical Systems/Engineering (which i don't )- DO YOUR RESEARCH if you want to start tinkering with theses settings. I left all these settings to adaptive/AUTO

WHAT I DID:
I know my chip can run @ 4.4 MAX/stable. But I realized I don't need that much and no need to push card harder than I need to. So,
Now I run @ 4.2 GHz with great temps, achieved by "Ratio Only tuning" through BIOS:
1. Set BCLK to 100MHZ
2. Set CPU Strap to 100MHZ
3. Set the Multiplier (Ratio) for each core to 42 (42 x 100 = 4.2Ghz)
3a. You can either choose "Per core" or "Sync all cores" -If they are all set to the same ratio this makes little/no difference from what I can tell. I imagine slightly more power draw with "all cores"
4. Left EVERYTHING ELSE on AUTO
5. (OPTIONAL) Turn OFF/Disable Intel Speed Stepping -this causes the clock to bounce around below stock speeds when idle -no need for this unless you care about power/energy consumption.

FANS:
The ASUS BIOS has whats called Q-Control for any fan connected to the mobo or fan extension card. Similarly, you can set each fan to PWM or DC, pick a preset, custom curve, or max speed.

I run may fans at max speed 100% of the time, my arrangement consists of 5 case fans and 2 CPU (1 required + optional 120mm) for a total of 7 -the max amount controllable without the extension card is 6 - I have one directly connected to PSU so it runs full speed but I can't adjust it. This is my configuration:

CPU: 2 x 120mm - PUSHING AIR TOWARDS BACK
BACK: 1 x 140mm - EXHAUST
TOP: 1 x 220mm - EXHAUST
FRONT: 1 x1 40mm - INTAKE
BOTTOM: 1 x 120mm - INTAKE (This is the "7th" connected directly to PSU)
SIDE: 1 x 220mm - INTAKE

Just always remember: Heat rises up naturally -so to trying and force exhaust out the sides/bottom/front wont work as well.

Now, to monitor my temps and fan speeds (in the absence of AI Suite) I use 3 free awesome programs;
SpeedFan, HWiNFO64, and RealTempGT, All available at Majorgeeks.com

HWiNFO64 monitors EVERYTHING, pretty rad.

Hope this helps!

Hi all !

I built my new PC with a 5820K cooled by a NH-D15 and 16Gb 2400Mhz Ram on a MSI X99A SLI Plus mobo.

I have a good 4,5Ghz at 1,250V (everything else set to "default" and Ram set on XMP), I'd like to push it a bit more maybe arround 4,7 or 4,8Ghz.

BUT ! (yes there's a "but" biggrin.gif ) even at 4,6Ghz pushed to 1,320V I get a BSOD so I though there was some other settings to move but I don't know which ones.

So here's my question : what should I do to get more speed ?

Thanks guys for your futur replies thumb.gif

Regards.

 

[DaSXTC]

NerdIT never set your voltages to AUTO, always change them to manualy or your hardware will get too much voltage!
It's only normal that it died using it the way you did.

DeathMetroll, 2400hz ram should be safe for an OC'ed cpu but I wouldn't go over 4.5 to keep it safe

Okay, I decided to change things up a bit. So I dropped the DDR4 speed to 2400mHz (from 2666) which brings the base clock back to 100. And I increased the multiplier for the CPU to ~44.5. I tried 45, but it was a bit toasty for my taste. So I switched the multipliers to "per core". As my hottest cores were 3 and 5, I dropped the multipliers of 3,4,and 5 to 44. But left 1,2,and 6 at 45. The result is a lot cooler for only a loss of 0.5gHz and the voltage is at a comfortable 1.26v.
Luv my 6 core baby, E

How do you change the xmp? Where do u even find it? Everytime I try to change my DDR4 clock to its stock 2666 it reverts back to 1333 for some monkey ass reason. My set up is exactly the same as yours, by the way. Except my cooler is corsair h100i. Haven't overclocked anything but my video cards yet.
