Introduction
It is hard to argue that the growing dollar exchange rate has seriously affected the buyers of computer components, because in just a year, hardware prices have risen by 30-60%. What do manufacturers apply, what steps are they taking to maintain their positions in the market? Who responded most quickly to the suddenly unfavorable situation? It will be easier to answer these questions if you look at the situation as a whole.

ASRock, ASUS and MSI make up the trio of the most popular motherboard suppliers, with a market share of almost 70%. And the most delicious part of the pie is the Intel Skylake CPU segment - with fresh processors, the likelihood of enticing shoppers is growing. But if earlier users forgave Intel's pranks and changed platforms when switching from one type of CPU to another, now people have become more discriminating.Of course, technologies do not stand still, but this time, instead of one intelligible step, we got only a semblance of it. For example, try to spot five differences between motherboards of the previous generation and the current one. Yes, new models are equipped with USB connectors 3.1, M.2 or U2, but without them it was possible to build a solid computer. Why then take an expensive motherboard if you can get by with a more modest version? Perhaps overclocking will say its weighty word when choosing? And here Intel has tried to cut off oxygen to customers as much as possible.
Manufacturers, seeing the decline in consumer demand, began to introduce new opportunities, including undocumented ones. But after that, Intel elevated the principles of segmentation of its products to the absolute - if you want to overclock now, just the CPU is not enough, you also need motherboard on Intel based Z170. And there is no doubt that under the onslaught of the vendor, manufacturers will sooner or later remove the ability to overclock processors without the "K" index. Apparently, right now it is important not to miss the moment, choose something suitable among hundreds of motherboards and stop updating the BIOS.
The aforementioned trinity also did not sit idly by and gradually saturated the Russian retail with more affordable models. And almost all of them have already been discussed earlier in a series of materials, broken down by sets of system logic:
- Budget options on Intel H110;
- Available models and solutions of a class higher on Intel B150;
Hello readers of the technoblog. Today I will tell you which processors are suitable for socket 1151 (Skylake, Kaby Lake), as well as 1151v2 (Coffee Lake). In this article we will try to talk about the most powerful, inexpensive and cheapest chips. Intel Core, Pentium and Celeron.
The list of CPUs will be lined up to give you a more accurate understanding of the models on the market.
And yes, it's worth making an important clarification: socket LGA1151 is not intended to be backward compatible with 1150 and does not support Xeon server processors.
Processor compatibility table
Socket 1151 from Intel is very tricky in its essence, since it has 2 versions: the first supports chips of the 6th and 7th generations, and the second only supports the 8th. The picture is much simpler in relation to it, but it’s not about him. 
Let's see which, as well as the i3, i7, Pentium and Celeron, are capable of running on 1151 Gen 1. 
Now let's take a look at the line of chips that will fit a motherboard with socket 1151v2. 
In 2018, 9th generation CPUs were added to the previous list. 
Optimal processor for its cost
Now for the fun part of the comparison. We have indicated which processor is suitable for a specific socket. Now it remains to decide on the model of the chip itself. If you want to know more about CPU, we recommend reading this article. 
And now let's go through the brightest representatives of the 6,7th and 8th generations:
Skylake- Intel i5 6400T engineering sample. In my time given processor made a lot of noise, because it had an extremely low cost, 4 productive cores with a frequency of up to 2.8 GHz and a very modest thermal package of 35 watts.
Kaby lake- Intel Pentium G4620. The so-called "Hyperpen" became cult among gamers at the time of its release, as it offered the functionality of Intel Core i3-7100 at a significantly lower cost. Also worth mentioning is the brisk mid-range i5-7400 and the top-end version of the i7-7700k, which has 4 cores and 8 data processing threads. The stone is considered to this day a relevant, powerful and interesting solution for progressive systems, and also supports overclocking up to 5 GHz in multiplier.
Coffee Lake- i5-8400. 8th generation arrives Intel chips added not only a new socket, but also 2 additional cores of each line, with the exception of Celeron and Pentium. Having a 6-core processor that can automatically increase the frequency from 2.8 to 4 GHz is a very good investment in the future, and therefore I safely recommend it (at prices for i5 you can navigate this (especially, many people know this discounter well, how reliable and verified seller)).
Difference between1151 and 1151v2
It has long been no secret that the processor socket intended for the 100 and 200 series system logic sets is completely incompatible with the 300. And it's not even that Intel wants to make money more money... The introduction of additional cores forced the engineers to fundamentally redesign the power supply of the Coffee Lake processors in order to ensure the stable operation of the chips, even under extreme overclocking. 
Key changes were made to the VCC (power) and VSS (ground) pads. At the same time, the number of previously reserved RSVD contacts has slightly decreased. Thus, the situation is as follows:
| Skylake / Kaby Lake | Coffee lake | |
| VCC | 110 | 128 |
| VSS | 364 | 378 |
| RSVD | 46 | 25 |
As you can see, it is physically impossible to “make friends” between old chips and new motherboards, just like plugging a Chinese plug into a European outlet. Yes, there are enthusiasts who managed to get Kaby Lake on the Z370 by modifying the BIOS, but the lion's share of the functions in this case was unstable, and the rest were completely absent.
So if you have a lot of free time, you can try, but I strongly advise against doing this.
I hope that the article was useful to you, so comment and share with your loved ones. See you in new articles. Bye.
LGA-1151 is a standardized and still valid socket for Intel 6th and 7th generation Skylake and Kaby Lake architectures. For interaction with the 8th generation of processors, an alternative version of the socket is provided - LGA 1151 v2, although it is similar in design to the "original", but differs in the approach to the organization of contact pads and power circuits, which ensure the stable operation of the chipsets installed in the motherboard under extreme load or when using non-standard cooling. The rest of the connector characteristics are similar - the same spring-loaded contact for contact with the processor, the familiar DMI 3.0 and PCI Express 3.0, the same mounting of tower coolers.
The approach is as follows:
- LGA-1151. Supports Core i7, i5 and i3 processors, as well as 6th and 7th generation Pentium and Celeron series belonging to Skylake or Kaby Lake.
- LGA-1151 v2. The Core i7, i5 and i3 and the Pentium and Celeron series are connected, but already the 8th generation, which are marked with the Coffee Lake marking.
Optimal processor
Among the available variety of processors, it is more difficult to distinguish some individual models than it seems at first glance. And the main reason for this is the lack of information. What is the cash ceiling? Will you need an upgrade in the future? Need gaming platform or office? If you do not go into details and focus on the only indicator - price / quality, then from Skylake it is worth noting Intel i5 6400T, from Kaby Lake - Intel Pentium G4620, and from Coffee Lake - i5-8400.
The second revision of the LGA 1151 socket appeared at the end of 2017, along with the release of the Coffee Lake series processors, which, as the developers from Intel immediately warned, were electrically incompatible with the "original" (due to changes that affected the number of contact pads responsible for power , signal transmission and processing of some processes, installation of old-generation processors on a new one is impossible - however, backward compatibility is not provided either).
Hence, in fact, the conclusion - the differences between the versions are reduced to the way of organizing power supply and electrical "feeding". And, since there is a desire to install a Coffee Lake processor, then you will have to look for LGA-1151 v2 motherboards (with DDR4 support), but if you need Skylake or Kaby Lake, then LGA 1151 with DD3 will do.
Top 10 motherboards with LGA 1151 socket
The choice of a motherboard with connectors of the first and second revision directly depends on the quantity Money and the preferred brand, and additional characteristics, such as a built-in Wi-Fi module or support for two or even four PCI-E x16 slots for installing video cards. And therefore, it is more difficult to parallel recommendations in such a vein than it seems at first glance - the chances of being reduced to subjective advice, and not to straightforward help, are too high.
And therefore, even before getting to know the top 10 motherboards, you should look into the nearest online store and, after placing the appropriate tags, start searching (you should immediately indicate the price, choose the manufacturer and form factor - for example, ATX or Mini-ATX, and at the same time - decide on the sound scheme or RAM slots). In less than five minutes, there will definitely be suitable options. And then - it remains to get acquainted with the reviews, read a few reviews and transfer the model you like to the basket ...
