When it was published to the material For the coverage of the new generation of skilike processors I was a bit confused. It was noted that the base frequency of the new K processors with the open product can be fully dynamic. In other words, it is possible to play with the frequency without dealing with the product and thus increase the processor frequency. At that moment I realized that something was going to be different in this generation. Since then, the base frequency modulation has been reserved for the exclusive K processors and is blocked to any other standard processor in the new LGA1151 chassis.

Recently, we learned that the motherboard manufacturer Asrok broke the dam and allowed the processor to run into the closed products by changing the base frequency only. Which Asus joined and as of this writing MSI and Expected soon.

How is this possible in the Skylike generation?

Here's a reminder of the internal structure of the new Skylike processors. Engineers Worked hard and managed to make a complex mechanism to work in a way that he could not have in the past four generations. It succeeded in completely disconnecting its base frequency, the BLCK, from various operating frequencies that were connected to it, such as the PCI-Express interface controller, the communication channel with memory, and other controllers that were fully synchronized. Thus the processor is released from five-year chains that held it out of potential And allow users to increase processor performance in exchange for higher power consumption.

The potential release now in the SkyLike generation is significantly stronger than what we knew five years ago, since we've been able to go down to the 22 lithography in nanometers and then back to 14 nanometers. The heat emission of processors has been significantly reduced and our ability to cool them improves.

Current limitations of the Skylike processor

There are currently some limitations and conditions under which they can be implemented The processor locked up. The first limitation at the time of writing is that the speed can only be made on certain motherboards, specifically the Z170 Advanced chipset. Not all boards based on this chipset support hardware acceleration. It is important to check the manufacturer's website in the various forums whether your motherboard is included in the list.

Another limitation we have known for decades is cooling and temperature monitoring. Skylike processors will not be recommended at all with simple refinements such as default או Alpine's simple ARCTIC example. Make sure you have it With copper pipes and a serious fan. In addition, after execution In base frequency upload mode we are simple Disconnect the internal processor controllers for temperature and voltage. Therefore, it must be 100 percent certain that the cooling will function properly.

If you decide to do so For the base frequency, you can also forget about the built-in graphics core. A dedicated video card installed in the Is a must.

The last limitation or disadvantage I will mention is the loss of certain command sets in the processor. This means that in very specific operations, you lose the advantage of adding processing power to the CPU in default mode. What actions? Well, it's hard to elaborate specifically simply because it depends on how you wrote the software.

Asrock continues to go wild - the motherboard we will use

Of course, it is impossible not to mention Asrok, which was the first to announce its SKY OC technology, a technology that enables the processor to be locked into processors after the BIOS update. Of course, the first motherboards participating in the capacity are the Z170 chip sets and more advanced series. This is probably due to the more advanced engineering that was already built in advance to deal with the increased power consumption that the K-speed processors force on the motherboard. In this tutorial I use the ASRUK® Z170 Extreme6. This advanced allows me to easily perform any action I want without worrying about his health.


It is reasonable to assume that H170 and B150 panels with advanced engineering will soon receive bios updates. This is quite sensational news for Overeklukers who are going to get out of a five-year coma from the LGA1156 section Which was the last to allow a full game with base frequencies.

Pentium G4400 - From the office to the rush table

The processor that I will demonstrate quickly in this tutorial is what I see from the quick - taking a simple and budget component and significantly improving it to reach a performance level that is generally more affordable. The G4400 is perfect for me. This is a LGA1151 Skylike processor that contains 2 processing cores without the addition of HyperThreading like its big brother, the i3.


It has a 3 megabyte of Cache, 3300 MHz operating frequency on 33 multiples of the fixed base frequency, 100 MHz. I'm going to pick up this base frequency while keeping the 33 multiples and demonstrate how it works with over-35 percent of the increment frequency. The price of this processor is around NIS 280 as of today.

The Trinity through which Can exist - Preparing for the rush

There are three essential components that, if only three are present, can be carried to the processor. The first is of course a processor. All Skylike's CPU The LGA1151 chassis will be suitable, even the K owners for this matter although the preference name is absolute towards increasing the product.

The second essential component is appropriate. As I mentioned is currently required The Z170 chipset owner, which has Bios that unlocks the baseband change to non-K series processors. In this case, the Z170 Extreme6 is used as an optional 1.82 XBUM.

The third and equally important component is the heat sink. The speed of each type increases the heat emission of the component. This is used inCooling the TPC812 of the Cooler Master. This tower will make it easy to cool the G4400 without worrying about high temperature under the extra serious voltage. Since I was criticized, I have adopted this cooling for such actions. Easy to install, own Christ, just pleasure.

How to perform the haste

After you have updated the BIOS to a version that supports haste for locked processors and installed It was time to roll up and go to Bussy.

The OC Tweaker tab allows you to set the base frequency, the BCLK of the processor. After the moderate levels, I reached the goal I set for myself that is 137 MHz for this frequency. It brings the processor on its 33 multiples to 4521 MHz which is an addition of 1221 MHz over the default.

In general, when we return to the game with the base frequency, a game with the memory frequency comes into play. The last time we had to set a memory frequency following a change in the base frequency was far away at the beginning of the decade. On 137 MHz it had to determine the frequency closest to the normal 2133 MHz frequency in the case of this test system.

2192 is not Exaggerated and stable for this memory. To take less risk, it is possible to work a little less, but not to drop too low. For me, anything under 2050 MHz will not be acceptable. Pressing the DRAM Frequency option allows me to select the available frequencies relative to the base frequency.

One of the hard parts of rushing to a locked processor is the power play. We need to rely on Asruk to monitor most precisely and correctly the voltage it should give the processor. There are two options where you can give voltage - Offset and Fixed. In Offset, we set a few millivolts above the default we want to give the processor in whatever mode it is in. Fixed mode allows one constant voltage that does not change much. If I know I can cool the processor under 1.35 high frequency, I'd prefer Fixed with this voltage. Map, just pull frequency and see where I'm coming in effort.

Stability testing can be done in several ways. I currently refrain from recommending Prime95 due to fear of a bug that could cause the system to freeze. This, at least until they have corrected BIOS to prevent motherboards. You can use LynX for example, or even a heavy rendition test like Cinebench in loops. Between steps in a hurry, the tests can be performed for about 10 minutes only. If you want to check for full system stability, you should run LynX for about two hours.

How far should you go?

A question that is asked each time a user approaches the rush. Let's get some things in order. First thing to remember - the base frequency speed depends on the height of the multiples. If you have an 40 multiplier processor on the fixed 100 MHz base frequency, then raising the base frequency to 120 will already cause it to climb to 4800 MHz, which is quite high in itself. Here's the difficulty I encountered in rushing the G4400 processor, a processor with a 33 multiplier to the base frequency:

Using the G4400 processor these are the degrees of difficulty I have encountered. Up to 120 MHz I did not even need extra voltage to the processor. Achieving 3800 megahertz as a frequency of action is a matter of minutes. At 130, things started to get a bit complicated by the addition of extra voltage. With small increments of voltage and frequency I set to target 4500 MHz (4521 to be exact) achieved with 137 MHz base frequency. The voltage required was in my case 1.32 volts but it will vary between Different even in the same model. So, how does 1200MHz affect processor operation?

Tests - An innocent processor becomes a demon קטן

The first test is a graphic test. I used the R9 290X Tri-X video card . Such a serious video card will be a heavy burden on the modest G4400. As you can see, the average number of images per second is quite similar. Note, however, that there is a huge difference in the minimum amount seen in this test. This dramatic difference between 24.7 and 35.3 A second can determine the level of pleasure from playing with heavy loads like explosions.

The second test is Cinebench R15. This test takes the processor on its cores to a complex rendering task and measures time. This time it becomes the score it receives from the processor at the end of rendering. Here, too, there is a very significant difference between 3.3 GHz and 4.5 GHz with an 33.9 percent advantage. The frequency of the processor is almost completely expressed in the rendering test. For comparison, The new 3 i6100 double cost brings a score of about 400 points in this test.

[visualizer id = "86505"]

The third and last test is the Winrar shrink test. This test is built into the software and measures the ability of the computer system to collapse as quickly as possible. The difference between default and default mode is 10.5 percent. Although not as big a difference as the other tests, but certainly respectable!

Summary - Risk and cost versus benefit

Have we returned to the glittering days of a LGA775 resident when he was To the neighbor and to the grandfather because we felt they deserved a few dozen percent more performance? not exactly. The extra performance exists, as you can clearly see, but what is the sacrifice we need to make for it?

First and foremost we will deal with ownership. At the time of writing, there is no really cheap motherboard that enables the speed of processors on it. Even among the only good and expensive Z170 boards were selected to get support. This is the least you can pay in Israel today on a motherboard that supports technology such as Asrok's Pro700. One of the reasons for this choice is the ability to appeal to a large clientele and give them the chance to compromise hardware. Today everyone is doing what is possible to reduce the amount of bad hardware. B- Set frequency limits to temperature, Intel blocks , And motherboard manufacturers also do not want warehouses full of hardware malfunction because the user decided to go one step too far.

Added great performance potential, especially for processors from the cheaper families
Additional potential Great, especially for processors from the cheaper families

Therefore, the LGA1151 slider is really for everyone. It is reserved for those who like the deal, who are willing to understand the risk, invest in equipment and get results. For everyone, there will be the speed with which I can take a motherboard in NIS 300, process 250 and cool in 50, and decide to add more 25 frequency to the processor. Technically, as long as you stay below the Core i7's highest power level, hardware will not have a physical problem to deal with the speed. The problem starts when you stretch the border with Have high power and add a few dozen more watts - the motherboards are not designed to deal with it, and are not over-engineered to do so. Just for that, there are advanced motherboards like the Extreme6.

In conclusion, I am generally happy about the decision to open the hurry to processors with locked products. I think the fun is fun, and the improvement in performance is not bad at all. It is preferable that the possibility exists under certain limitations rather than merely existing. Will a wider range of motherboards offer support? We will know this later this year with the launch of More.

For those who already have the tools, they also want to experiment with the multiplicative lifting of multiples in each processor - you are also welcome to share your results with us. Wish you all Safe and stable.
