Help boosting I7 8700k 3.7 ghz to 4.7ghz

[Elliott]

Hello, Im new to PC so I don’t really understand what to do. I have a i7 8700k 3.7 ghz, apparently this cpu has a max frequency of 4.7 ghz. I went into my BIOS and turned on intel turbo boost and set my power to high performance and now my cpu reaches a max of 4.3 ghz. My question is how to I get my cpu to its max frequency (4.7ghz)? Do I go into my bios and just change all my core multipliers to 47? And also will this give me a little more FPS in games? And can It harm my pc??? I don’t want to overclock over its max frequency only within its limits. I also have a pretty good liquid cooler so the heat shouldn’t be a problem, if it is I’d set it back to normal. I’d appreciate easy to understand solutions please as I don’t really get the pc stuff yet

There should be enchanced multi core , or multicore enhancement in BIOS. Enable it and that should get all cores to 4.7 automatically.

I heard doing it that way makes it unstable? What voltage do you have on yours after doing it that way?

As far as i know it as profile loaded by vendors differentley. Each vendor applies different voltage to Multi Core Enhancement. I havent used it on mine as i went straight to 5Ghz on my 7700K. You should try it on your motherboard. If the voltage is above 1.35 then disable it and just set all cores to 4700Mhz and maybe give 1.28-1.29 volts. It should work for that modest overclock.

Highly depends on the Silicion lotter what you can obtain. Voltage can go up to 1.52V but then you need a really good PSU and VRM/Mosfet not to rbeak your motherboard. If you have a really good motherboard to overclock you could even go beyond the rated 1.52V. You main limitation you should not overcome as that is the actual way of drainign your hardwares life and risk damage is the temperature.

Every thing is safe to that point where you activly disable secrutiy features as thermal throtteling. Also for starters I wouldnt go further then 0.1V below max rated voltage (max rated is 1.52V so dont go further then 1.42V). Also if something breaks to overclocking it cant be prooven by the manufactur most of the times.

The hardest thign in Overclocking is the Trial and error phase. it is really time consuming. Do long time stress test best over night.


Full Gigabyte Overclocking Guide:
Follow it to the letter. And you're safe

What you need to start overclocking:

-MSI Afterburner, NZXT CAM, HWMonitor etc (somethign where you can monitor your CPU temperature in real time.
-Prime 95 v26.6 (exact that version)
-A good CPU cooler

Prime 95

Like mentioned befor you need version 26.6. It is a Stress Test to see if an overclock is and remains stable over a longer time.
-If you start P95 you have 2 options: "Join GIMPS!" and "Just Stress Testing". Select "Just Stress Testing".
-From the 4 options you have to choose from the select "Custom"
-Set both "Min FTT size (in K)" and "Max FTT size (in K)" to 1344.
-Every time I tell you to run P95 run that program with thsoe settign and press start.
-If nothing happens during that test, everythign is fine. If a worker stopped or you getting a BSoD the verclock is unstable.
-Monitor your temperature for the first 20 Minutes (with an Air Cooler) and the first 30 Minutes (with an Water Cooling System) closely. If The temeprature exeeds 90C abort the test. After those crucial minutes of heating up you can relax and can check after hours. Those minutes the system needs to catch up with coolign and stabilize the temperature.

Phase 1: Setting up the system

1st: Enter Bios by pressing F2 during boot.
2nd: Select M.I.T. -> Extreme Memory Profile (X.M.P.) -> Load a profile when available
---> This will overclock your RAM to manfucaturer settings
3rd: Select M.I.T. -> Advanced CPU Core Settings -> Advanced Frequency Settings ->Disable:
- Speed Shift Technology
- CPU Core Enhanced Halt(C1E)
- C3 State Support
- C6/C7 State Support
- C8 State Support
---> This very basically explained will let CPU constantly run at the maximum allowed Clock Rate while preventign other cores to go into a sleep mode where they are effeictivly deactivated. That is the huge difference between Overlockingand Turbo Boost.
4th: Select: Chipset -> Disable
- VT-d
---> Even though that it is not what VT-d means, on Gigabyte Motherboards that setting enabled will mess around with your OC and oevrwrite your settings push you back into very low limits.
5th: Select M.I.T. -> Advanced CPU Core Settings -> Advanced Voltage Settings -> Advanced Power Settings -> CPU Vcore Loadline Calibration -> Set with the number 1-7 either Turbo or Extreme. Recommend only to choose Turbo with your Motherboard.
---> This will later help to maintain amuch mroe stable voltage and also more stable overclock where you can overclock higher.

Phase 2: Finding out your maximum Voltage

This Phase is about finding out how high you can rise the voltage without overheating. For safety reason I will remind you to absolutly stay below 1.420V. I can promise you though, that you wont get close to it as you overheat before.
We have to set a fixed voltage oevr an adaptive voltage to keep the system more stable. Also, a fixed voltage has nearly always a lower voltage then the adaptive voltage would set for you. That directly influences in lower temepratures and a more stable voltage without spiking ensuring that you have less worn on your hardware ands stay as safe as possible.

1st: Go back into Bios if you not still in it.
2nd: Select M.I.T. -> Advanced CPU Core Settings -> Advanced Voltage Settings -> CPU Core Voltage Control -> CPU Vcore (type the number in like 1.***V, make sure to write a dot, then 3 numbers after the decimal dot followed by a large V without space like 1.350V)
3rd: Select your desired Voltage, start with 1.350V
4th: Save and Exit Bios.
5th: Run P95 for 20 or 30 minutes depnding on your cooler. Monitor your temperature.

- If the temperature was between 75-80C continue with next phase
- If the temperature was below 75C get back to Step 1-5 and raise the Voltage by 0.100V or 0.050V
-If the temperature was above 80C get back to Step 1-5 and drop the Voltage by 0.100V or 0.050V

Phase 3: Finding out your maximum stable Clock

In this phase we going to change the multiplier to overclock the CPU as high as possible within limits.

1st: Go back into Bios
2nd: Select M.I.T. -> Advanced CPU Core Settings - Advanced Frequency Settings -> CPU Clock Ratio
3rd: Select your desired multiplier (desired Frequency / 100). For 4700 MHz you type in 47. Start with 49.
4th: M.I.T. -> Advanced CPU Core Settings - Advanced Frequency Settings -> Uncore ratio
5th: Select and uncore multiplier 4-5 lower then your CPU Clock Ratio. The lower it is, the m
ore performance you loose while being more stable
5th: Save and Exit Bios

- If the PC doesnt boot and throws you back into Bios, get back to step 3 and select a lower multiplier and/or Uncore. Otherwise continue with Step 6.

6th: Run P95 for at least 60 minutes.

- If temperature crossed 90C, consider the test as failed. In that case lwoer the voltage you set in Phase 2.
- If the test failed (not becuase of overheating), go back to Step 1 and select a lower multiplier in Step 3

Phase 4: Voltage optimizing

Basically the Same as Phase 2 just with final Voltage setting.

1st: Get into Bios
2nd: Lower Voltage in small steps (even possible in 0.005V steps like 1.425V)
3rd: Save and Exit Bios
4th: Run P95 for at least 60 minutes.

- if the test fails, go back to the last lowest stable Voltage you foudn and raise the voltage again. Continue with step 1-4.
- if you found the lowest possible Voltage after 60 minutes P95, raise that volatge by 0.05V to get a voltage headroom and betetr oevrall stability.

5th: Do a last 12-24h long time stress test with P95 in FTT 1344K

Tweaking

you can tweak the Overclock further by trying to raise the multiplier even though it wasnt stable Go into Bios: M.I.T. -> Advanced CPU Core Settings - Advanced Frequency Settings -> AVX Offset between 1-5. That will lwoer the multiplier by that rate inspecial task and could allwo you to OC higher.
Better temperatures and therfor high OC can be reached by:
- Getting a better cooler like NZXT Kraken x62, NZXT Kraken x72, Corsair H115i, Corsair H150i, Noctua NH-D15, BeQuite Dark Rock Pro 4
- Getting a custom Loop with at least a 280mm Radiator.
- Delidding your CPu and changing the TIM with Liquid Metal, Recommend Coollabratory Liquid Pro or Thermal Grizzly Conductonaut
- Swapping your IHS during delidding with a custom pure copper IHS that also has a larger surface area.

I have the same CPU. It also reads as 4.3. The 4.7 is only on 1 core.
If you look at the multipliers in bios they are different with only 1 at 47x100.

I don't think you need 6 cores at 4.7ghz just for browsing and opening emails and stuff and at stock settings it's already a beast of a CPU for gaming.
It doesn't hurt to have it step down off load

I understand what you mean but its not stepping down, it boosting up when needed but unfortunatly only with 1 core. if you have multithreaded games they profit highly from overclocking and both the motherboard and CPU is build for it. Why not get extra free perfromance? Its not like the CPU will idle when doing nothing, same when you overclock. power consumption even stays overall the same and lower then with boosting.
Also we already far through Turbo bosot in this thread. The OP specifically asked how to run all cores at boost speed. Thats how we came to overclocking.

PS: Imo you not get a 8700K for mail and browsing in the first palce, you do it for gaming or light workstations. In both cases you woudl profit from free eprformance bosot by overclocking.

Yeah I understand that but I don't like mine running at boost speeds when I'm not gaming or working. It's unnecessary.
I got the feeling the OP was concerned his chip wasn't set up right as it was showing only 4.3Ghz. I was the same with my new build, having come from Haswell where all 4 cores sat at 3.8Ghz permanently, I thought the 8700k would be the same.

With windows power plan on balanced and C states enabled it certainly will step down when doing nothing. As low as 800Mhz.

All good if OP wants to OC. As long as he knows his CPU is not broken showing 4.3

You can force your CPU to run at the much much lower clocks by using "Power Saver" in Windows Power Options. This is perfectly fine for things outside of gaming and demanding work apps like video editing and alike. But this will most likely only trigger lower clocks if you leave such features enabled in BIOS regarding things like "Intel SpeedStep / SpeedShift" or "AMD Cool & Quiet"

Now due to how the "Power Saver" profile happens to be configured by default, you may wish to slightly edit it, putting a stop to things like sleep timer, monitor off; things of that sort.

Then before loading up a Game or other high-demand App, switch over to the "High Performance" profile.

Can also help to change setting in your web-browser to disable hardware acceleration, so browser doesn't put un-wanted loads on your GPU for basically no reasons. If you find the browser runs like crap, then switch it back on.
