Conroe, Sandy Bridge, Ivy Bridge, Haswell, Skylake, and anything in between, we’ve overclocked them all. Each had their pros and cons, but the standout architecture in that list is Sandy Bridge. Good samples were capable of achieving stable overclocks of 5GHz on air cooling. It’s a landmark that has proven elusive, until now. Finally, we have a worthy successor: Kaby Lake. Intel's latest processors make 5GHz overclocks possible with air cooling, and you even can go beyond that. No need for lengthy intros when excitement levels are at fever pitch. Let’s get down to business!Frequency expectations – i7-7700KOur R&D dept has tested hundreds of CPUs and found the following frequency ranges are workable for overclocking Kaby Lake i7-7700K CPUs: 20% of samples are stable with Handbrake/AVX workloads when running at 5GHz CPU core speeds. The AVX offset parameter can be used to clock 80% of CPU samples to 5GHz for light workloads, falling back to 4.8GHz for applications that use AVX code. The ASUS Thermal Control Tool has now been ported into UEFI and can be used to configure profiles for light and heavy (non-AVX) workloads to extend CPU core overclocking margins on air and water cooling by up to 300MHz. Memory frequency: The best CPU samples can achieve speeds of DDR4-4133 with four DIMMs (ROG Maximus IX series of motherboards needed). DDR4-4266 is possible on the Maximus IX Apex. For mainstream use, we recommend opting for a memory kit rated no faster than DDR4-3600, as all CPUs are capable of achieving such speeds.CPU power consumption and cooling requirementsOne of the questions that always arises when we’re dealing with overclocking is "how much Vcore is safe?" Generally, we recommend constraining an overclock to stay below 2 X the stock power consumption of the processor under full load. To work out what that figure is, we can measure the CPU’s power draw via the EPS 12V power line using an oscilloscope and current probe.To generate workloads, we tested with the brute-force loads of Prime95’s small FFT tests (AVX2 version) and also with ROG Realbench, which uses real-world rendering and encoding tests. Using both “synthetic” and real-world tests allows us to establish voltage recommendations for both scenarios.Don’t fret if you can’t understand the captures, we’ve performed the calculations for you and show the figure in Watts beneath each image.Stock frequency, ROG Realbench load current = ~45WStock frequency, Prime95 load current =~76W5GHz CPU frequency, ROG Realbench load current = ~93W5GHz CPU frequency, Prime 95 load current=~131WWith the data acquired, we can identify where our “self-imposed” limits lie. We will add our obligatory disclaimer at this point and state that overclocking has risks and voids warranty unless you opt for Intel’s Performance Tuning ProtectionAsus RealBench 2.56 - Download
To come back and tweak settings such as cache (Uncore) frequency, System agent voltage, VCCIO (Internal memory controller) and memory speeds or timings (RAM) AFTER the CPU overclock is fully stable.Save bios settings (As a new BIOS profile if your bios supports multiple profiles) and exit bios.Boot into the Windows desktop environment. Download and install Prime95 version 26.6.Download and install either HWinfo or CoreTemp.Open HWinfo and run "Sensors only" or open CoreTemp.Run Prime95 (ONLY version 26.6) and choose the "Small FFT test option". Run this for 15 minutes while monitoring your core/package temperatures to verify that you do not exceed the thermal specifications of your CPU. (This should be considered to be 80°C for most generations of Intel processor and for current Ryzen CPUs. For older AMD FX and Phenom series, you should use a thermal monitor that has options for "Distance to TJmax" and you want to NOT see distance to TJmax drop below 10°C distance to TJmax. Anything that is MORE than 10°C distance to TJmax is within the allowed thermal envelope.)If your CPU passes the thermal compliance test, move on to stability.Download and install Realbench. Run Realbench and choose the Stress test option. Choose a value from the available memory (RAM) options that is equal to approximately half of your installed memory capacity. If you have 16GB, choose 8GB. If you have 8GB, choose 4GB, etc. Click start and allow the stability test to run for 8 hours. Do not plan to use the system for ANYTHING else while it is running. It will run realistic AVX and handbrake workloads and if it passes 8 hours of testing it is probably about as stable as you can reasonably expect.If you wish to check stability further you can run 12-24 hours of Prime95 Blend mode or Small FFT.You do not need to simultaneously run HWinfo or CoreTemp while running Realbench as you should have already performed the thermal compliance test PLUS Realbench will show current CPU temperatures while it is running. If you run the additional stability test using Prime95 Blend/Small FFT modes for 12-24 hours, you will WANT to also run HWinfo alongside it. Monitor HWinfo periodically to verify that no cores/threads are showing less than 100% usage. If it is, then that worker has errored out and the test should be stopped.If you find there are errors on ANY of the stability tests including Realbench or Prime95, or any other stress testing utility, you need to make a change in the bios. This could be either dropping the multiplier to a lower factor or increasing the voltage while leaving the multiplier the same. If you change voltage or multiplier at ANY time, you need to start over again at the beginning and verify thermal compliance again. A more in depth but general guide that is still intended for beginners or those who have had a small amount of experience overclocking can be found here: *CPU overclocking guide for beginnersThanks for providing all of that. 😀So I.

The target value. For most users, this setting can be left at the default unless you need to use an offset to lower the voltage below the minimum adaptive voltage for the applied CPU ratio.Note: The CPU Package temp is utilized by the ASUS Thermal Control tool because it represents the average core temperature reported by the internal thermal sensors over a 256-ms period – this makes it a perfect choice for the task.Making use of ASUS CPU overclocking temperature controlIn order to make use of the temperature control features effectively, we need to make a two-point evaluation: Testing with games/light-load applications at the upper CPU frequency Using the Thermal Control Tool with an all-core test – ROG RealBench stress test recommended.In our case, the CPU is Realbench stress test stable at 5GHz with 1.35 Vcore. With that in mind, it should be possible for us to run light-load applications at 5.1GHz using the temperature control function.Tuning Vcore for the light-load frequency can take some time. When a heavy-load application is run, there is a momentary delay before the clock frequency drops to the throttle target. That is because temperature changes lag behind the execution of a workload. Vcore needs to be sufficient to handle the momentary load before the clock frequency drops to the throttle target. You will need to bear this in mind when tuning – be prepared to provide some headroom for Vcore! We recommend using the application you intend to run at the throttle frequency. The heaviest load we recommend for this portion of testing is Handbrake with a maximum of 1.43Vcore at the upper frequency. This will avoid excessive current draw before the clock speed is lowered to the applied throttle frequency and voltage.We also need to be mindful when setting the CPU temperature upper threshold. If set too high, the CPU remains at the light-load frequency for too long; this can result in instability unless we provide sufficient Vcore to handle a heavy workload. The temperature control mechanism needs adequate time to react and lower the CPU frequency to our chosen throttle point.For frequencies above 5GHz, we have found that values under 65 Celsius are best because higher temperature thresholds need more Vcore. It is better still if one sets the threshold closer to the peak temperature that the “most intensive” light load generates. That said, if using good cooling for the CPU, you should not see temperatures over 60 Celsius during light loads, anyway.To make things easier for you, we’ve included a sample screenshot of our temperature control settings for a 5.1GHz overclock that drops to 5GHz under heavy loads and to 4.9GHz under AVX workloads.When the CPU temperature exceeds 60 Celsius, theIs this a respectable RealBench Score? - Asus
Have to draw a line somewhere. And small fft test gives a good clear load (unlike Aida or Occt) which is sort of important for baselune comparisons with aios that run 15-30minutes to stabilize.It's even more important to have a single standard, something anyone can interpret and recognise. Saying you get 75° in p95 sfft, that's easy. Golden. Cooling is good. Even pushing games hard you'll not see that number, or very far beyond in AVX heavy games.But with variables in Aida, occt, IBT, CB versions, who uses linpack, who doesn't, what degree of ram is used, what degree of cpu is used etc nothing is solid. There's no base for comparison to real world.Prime is good for temps, that's basically it. The newer versions changed how they did things, use different coding etc, same results, but it's not really reliable for stability . Cinebench, Asus RealBench, even Aida are much better for stability now.It's like saying a pitcher has a 100mph fastball. That's only true 6/10 times, 3/10 it's 99mph,1 time it's 101mph, but it's a good number to compare to the backup pitcher's 96mph fastballs. Doesn't mean his curve ball is that fast, nor his slider, or if he'll throw 100mph balls the entire 9 innings, might only throw 3 of them, it's a measure of what's possible, a baseline to judge from, if not necessarily a 'real world' number usage.

Hey everyone,System Info:Ryzen 5 3600 4.2ghz @ 1.125v AllcoreB450M Mortar Max Bios: 7B89v2D Agesa 1.2.0.2, previously 1.1.0.0 with no improvement.Chipset Driver: 2.13.27.501 - 2/4/2021Gigabyte RX 6700 XT - 21.5.2 DriverSfc /scannow - chkdsk - DISM, no problems.PSU - Seasonic Core GM-650w(Gold)30mins Asus Realbench, ~200% mem test pro stable, all kinds of real world load use stable prior to MAY 2021, 5 hour gaming sessions, 3 hour video rendering etc. General use Temps under 72C max load,, Then randomly, over the past month at idle, things like youtube or launching a game started triggering a blackscreen/crash with Cache Heirachy Error, this has happened mostly over the past 30 days after setting HWinfo to start with system & simply leaving it on. (I was using it less prior & not running it 24/7),, now originally at the start of the month, I was getting this error on Agesa 1.1.0.0, & it continued after updating to 1.2.0.2 in an attempt to resolve the problem on May 10th, with no improvement,, over the month of May I had the Cache Hierachy Error ~11 times at seemingly random times on random Processor APIC ID's, sometimes with two different processor APIC IDs causing a cache error at exactly the same time.After the crash and attempting to reproduce the issue, I could not force it to crash again by performing the same actions via applications, but sometimes it would crash when left idle again without me noticing, for only a few hours of idle.

Plan. Keep that in mind, as there’s no way for us to guarantee things won’t go awry if you overclock a CPU. All risks are your own. What follows is nothing more than a set of guidelines based upon our own experience.In order run Prime95 at 5GHz, our CPU sample requires 1.35Vcore. Power consumption under that load comes in at 131 Watts, which is comfortably below 2X the stock power consumption of Prime95. I must confess, CPUs are usually power rated by application power rather than Prime95, hence leaving some headroom below the 2X figure is prudent.So, if you’re running Prime95 as a short-term stress test, we advise using no more than 1.35Vcore with a 7700K CPU. If the CPU has not been de-lidded/re-lidded for a thermal paste upgrade, you’re likely to run out of thermal headroom around that voltage anyway.Now, if you happen to be the type of user that spends more time running Prime95 than using a PC for other tasks, then we advise you reduce the maximum Vcore. "By how much?", you ask. Well, you’re on your own for that. Remember, it’s current that degrades or kills a CPU. Be mindful of how much load you’re placing on the chip long-term and act accordingly. There’s nothing worse than pushing insane levels of current through the die and then moaning when there’s degradation.Realbench is far kinder to the silicon from a power consumption point of view. At 5GHz and 1.35 Vcore, the power drawn is only 93 Watts. The risk of degradation is far lower than when subjecting the CPU to the brutality of AVX-enabled versions of Prime95. In fact, you could push up to 1.40Vcore with Realbench, and still keep consumption below the power levels drawn by Prime95 at 1.35 Vcore, but that's as far as we'd go for sustained exposure to such workloads.Immediately apparent from this data is the fact that Kaby Lake is very power efficient. Sub-150-Watt power consumption when dealing with the nasty loads of Prime95 at 5GHz is incredible. Even if you were to find a gem Skylake CPU capable of operating at the same frequency, power levels would be up around the 200 Watt mark to obtain stability. The upshot is that Kaby Lake's efficiency takes the focus off motherboard power delivery to a reasonable extent. Any motherboard costing more than $150 should be capable of overclocking these CPUs to the limits when using air or water cooling. That includes all the ASUS motherboards in our Z270 guide.With the power side of things dealt with, we can take at whether the Kaby Lake architecture responds to lower temperatures when overclocking.

Should try Realbench now? I am happy with how my PC is operating at those settings to be honest. Jun 24, 2014 82,124 8,141 176,790 #4 Yes, you should. Because if it can pass 8 hours of Realbench, and you want to run ALL 8 hours. If it runs for 7 hours and 30 minutes, and errors out, it is not stable. If it runs for 7 hours and 59 minutes, it is not stable. Even if it runs for 8 hours, and errors out at 8 hours and five minutes, it is not FULLY stable, but the chances are very, very good that if it can run 8 hours of Realbench, you will never see an issue with corruption of data due to micro-errors, which is something you will never notice during normal use or gameplay until it has cumulatively corrupted your file system and data to the point where it begins showing problems and errors in the file system become evident.At that point, all is lost. None of the data can be "fixed" or recovered. If there are errors, you want to know about them NOW so you can either reduce the multi or increase the voltage, and then test again.

In fact, if you can pass with half your memory allocated, it's a pretty good idea to run it again with the full installed capacity of memory as well. OR, run it WITH the full amount the first time, and if there are errors, try it again with half theDownload ASUS RealBench 2.5.6 - MajorGeeks
[SOLVED] Is Prime 95 Small FFT with AVX necessary to determine stability of 9900k OC? Thread starter Thread starter Norrat Start date Start date May 24, 2020 You are using an out of date browser. It may not display this or other websites correctly.You should upgrade or use an alternative browser. #1 I've read that this test puts unrealistic workloads on the cpu and isn't suitable for a 9900k but there seems to be some debate about it still.My overclocks pass 8h - Realbench (Half RAM selected/No WHEA errors), 8h Prime95 Blend (AVX Disabled), 4h - Memtest, 2h - Aida64 Stress FPU, 2h - Prime95 Small FFT (AVX Disabled) - is this enough?

Careful though, as P95 with AVX on is rough for many coolers, so I suggest you disable AVX for the first couple of test runs. #5 I've run 15min with AVX off a few times . My max temps were 74c, already pretty warm. Dec 30, 2016 21,608 5,739 104,690 #6 Nice!

Hi EveryoneSo ive just upgraded from my Rampage V as I had bios issues (Need to RMA)I now have the Rampage V Extreme 10 with the 6850K and so far the board itself is rock solid very happy 😄Now to the issues and advice part, one of the issues i have is with the plastic "peely" that was attached to the top left IO heatsink, basically there was one on top which came off really easily, but there was a second with a pull tab underneath, the damn thing would not come out no matter what i did, so half of its stuck in there and the other half ripped off, I also used tweezers to try and loosen it but ended up scratching the god damn thing it was protecting :mad: anyone else had this issue?The other problem I seem to be facing is with my CPU fan control, I currently have my top rad (8fans) connected to the fan header and on boot and below 75% the fans flash (ramp up and down quickly) Im assuming this is because im going over the 1amp maximum for the port, I have also populated the 3amp port with the bottom rad (8fans) and that seems to be fine.Now the next thing I wanted to double check was my overclock, seems pretty good but wanted to check if there was anything else I could tweak (up or down)Memory - XMP 2800mhz (Corsair Dominator Platinum 2666)CPU Ratio is set to 44 (4.4GHz)Cache Ratio is set to 36Voltages - CPU 1.37v / Cache 1.15v / CPU input Voltage 1.920v / Memory 1.35v / Everything else set to autoI have stress tested for 6 hour with asus realbench, accidentally left HCI memtest running for 8 hours overnight (fell asleep) and also ran a few benchmarks and cinebench and all seems very stable, max temp on the cpu was 70c tended to bob around 65c on most cores.Thanks again for any advice you can give.Comments

That said, if using good cooling for the CPU, you should not see temperatures over 60 Celsius during light loads, anyway.To make things easier for you, we’ve included a sample screenshot of our temperature control settings for a 5.1GHz overclock that drops to 5GHz under heavy loads and to 4.9GHz under AVX workloads.When the CPU temperature exceeds 60 Celsius, the

And small fft test gives a good clear load (unlike Aida or Occt) which is sort of important for baselune comparisons with aios that run 15-30minutes to stabilize.It's even more important to have a single standard, something anyone can interpret and recognise. Saying you get 75° in p95 sfft, that's easy. Golden. Cooling is good. Even pushing games hard you'll not see that number, or very far beyond in AVX heavy games.But with variables in Aida, occt, IBT, CB versions, who uses linpack, who doesn't, what degree of ram is used, what degree of cpu is used etc nothing is solid. There's no base for comparison to real world.Prime is good for temps, that's basically it. The newer versions changed how they did things, use different coding etc, same results, but it's not really reliable for stability . Cinebench, Asus RealBench, even Aida are much better for stability now.It's like saying a pitcher has a 100mph fastball. That's only true 6/10 times, 3/10 it's 99mph,1 time it's 101mph, but it's a good number to compare to the backup pitcher's 96mph fastballs. Doesn't mean his curve ball is that fast, nor his slider, or if he'll throw 100mph balls the entire 9 innings, might only throw 3 of them, it's a measure of what's possible, a baseline to judge from, if not necessarily a 'real world' number usage.

What I want to know is I can give it any video transcode job and never worry about coming back after 1/2 hour to
2025-04-12Plan. Keep that in mind, as there’s no way for us to guarantee things won’t go awry if you overclock a CPU. All risks are your own. What follows is nothing more than a set of guidelines based upon our own experience.In order run Prime95 at 5GHz, our CPU sample requires 1.35Vcore. Power consumption under that load comes in at 131 Watts, which is comfortably below 2X the stock power consumption of Prime95. I must confess, CPUs are usually power rated by application power rather than Prime95, hence leaving some headroom below the 2X figure is prudent.So, if you’re running Prime95 as a short-term stress test, we advise using no more than 1.35Vcore with a 7700K CPU. If the CPU has not been de-lidded/re-lidded for a thermal paste upgrade, you’re likely to run out of thermal headroom around that voltage anyway.Now, if you happen to be the type of user that spends more time running Prime95 than using a PC for other tasks, then we advise you reduce the maximum Vcore. "By how much?", you ask. Well, you’re on your own for that. Remember, it’s current that degrades or kills a CPU. Be mindful of how much load you’re placing on the chip long-term and act accordingly. There’s nothing worse than pushing insane levels of current through the die and then moaning when there’s degradation.Realbench is far kinder to the silicon from a power consumption point of view. At 5GHz and 1.35 Vcore, the power drawn is only 93 Watts. The risk of degradation is far lower than when subjecting the CPU to the brutality of AVX-enabled versions of Prime95. In fact, you could push up to 1.40Vcore with Realbench, and still keep consumption below the power levels drawn by Prime95 at 1.35 Vcore, but that's as far as we'd go for sustained exposure to such workloads.Immediately apparent from this data is the fact that Kaby Lake is very power efficient. Sub-150-Watt power consumption when dealing with the nasty loads of Prime95 at 5GHz is incredible. Even if you were to find a gem Skylake CPU capable of operating at the same frequency, power levels would be up around the 200 Watt mark to obtain stability. The upshot is that Kaby Lake's efficiency takes the focus off motherboard power delivery to a reasonable extent. Any motherboard costing more than $150 should be capable of overclocking these CPUs to the limits when using air or water cooling. That includes all the ASUS motherboards in our Z270 guide.With the power side of things dealt with, we can take at whether the Kaby Lake architecture responds to lower temperatures when overclocking.
