Detailed guide for choosing a laptop operating system / Blog company Kingston Technology / SurprizingFacts

Hello GT! The pernicious tendency to make notebooks all thinner and thinner has already deprived us of upgrades and placers of ports. At best, the manufacturer gives a replacement drive, at worst – offers to buy an ugly and indecently expensive docking station with additional connectors.

Fortunately, professional and gaming laptops still remain true to the old concept of a personal computer in which you are free to upgrade hardware. About the upgrade of the memory subsystem today and we will talk.

Frequency potential and memory with nonstandard characteristics

The old DDR3 is still actively on the market – even the "flagship" MacBooks still use it, and not a new standard: the benefit, Intel Core processors of generations Skylake and Kaby Lake are able to work with both types of memory, albeit with some limitations. Since the memory controller of the CPU is one, and the normal for the "new" memory are voltages of 1.2-1.35 Volts, then the DDR3 must also be L (low voltage) at the end and lowered to 1.35 operating voltages. However, in our time on mobile platforms only such memory is present, and modern production technologies allow making memory working at 1.35 volts and 1.5 volts, and any mobile DDR3 from Kingston will suit both a laptop and a compact system with "

According to specifications, the last two generations of i3 / i5 / i7 processors in notebooks support DDR4-2400 MHz, DDR3L-2133 MHz and DDR3L-1600 MHz: at first glance the choice is not Is great. However, the same restrictions formally exist on desktop processors and are successfully managed through the BIOS of the motherboard. In support of the above, you can give examples of laptops with factory installed modules DDR4-2800 MHz and the same MacBooks with their 2133 MHz DDR3L.

Overclocking on the laptop

Since the greedy managers of Intel blocked the overclocking for mere mortals, demanding a co-payment for "now-not-so-and-so-and-free" megahertz, overclocking of the RAM on laptops is available in two cases: you have a flagship model and a processor with the HK index (i7 -7820HK, i7-6820HK) or on thematic forums there are modified (or "clammy" from the manufacturer) BIOS for your model with the unlocked tab of advanced settings.

To ensure comfortable conditions in monstrous ASUS ROG GX800V uses a hybrid cooling system ASUS, MSI and Lenovo have in the last generation transferred their flagship gaming laptops to an advanced memory standard, but Who said that the laptop with the conditional i7-4960HQ is about to retire? Yes, video cards of three years ago in modern games are working so-so, and even mobile video cards – and worse, because the performance of graphics in the "big brother" and the mobile PC equaled only in this generation, but at "medium" Then you can play? And conditional fotoshopam, illustrators and other tri-de-maksam generally do not care about fashion technologies: OpenGL is supported, 1-2 GB of video memory is – and well. And the rest can be put into a fast RAM if that.

Compatibility table

To simplify the upgrade of the old systems, we have compiled a small tablet that will help you make the right choice of RAM for your iron friend.

If your laptop runs on a graphics card embedded in the processor and manages a "slow" factory memory – when upgrading it's worth replacing the old module with a couple of fastest ones by matching your system.

iGPU does not have its own memory resources (except modest in size cache and frame buffer), and exploits the system RAM for storing models, textures and results of intermediate computations, and a slow memory subsystem – Bottle neck for comparatively powerful versions of IntelHD (530 and higher, and, of course, a good graphics class Iris and IrisPro). Details on accelerating the operation of the processor's built-in video core by replacing the RAM can be read in our previous article.


With DDR4 memory, everything is a bit simpler: it is supported only by two generations of mobile systems based on the Intel Core 5000 and 6000 series, and in gaming laptops (and also some monoblocks and ultracompact PCs), usually a sufficient amount of RAM is available from the factory. From both generations there are exceptions – the flagship i7 "mobile" series with overclocking support – their memory controller provides the operation of high-speed modules and supports overclocking.

The release of memory at frequencies above is expected in the near future

Unfortunately, Intel has implemented a wide support for high-speed memory SO-DIMM DDR4 with a frequency of 2800 MHz only in one processor on the market (and it lives in indecently expensive systems), and AMD has not yet shown mobile Ryzen'y: Kingston simply was not engaged in an unpopular direction, and in notebooks with i7-7820HK very rarely not set the maximum volume (64 GB) out of the box.

Flour choice and pitfalls

For most active users, the GT upgrade is unlikely to be an abnormal situation, and a clear understanding of the required volumes of memory is supplemented by a good knowledge of the iron part, that's only SurprizingFacts has become so popular that articles from it regularly divorce on social networks and shamelessly rummage to other resources even without reference to the source , So we can not ignore some obvious moments.

How can I find out the current amount of memory and its characteristics?

The most easy is for Windows users 10. Open the task manager (Shift + CTRL + Esc), in it the "Performance" tab and go to the memory section:

A specific processor model?

Everything is the same, but in the "CPU" section:

What should I do if I have Windows 8 / Windows 7?

You can use the free utility CPU-Z – it will show exhaustive information about the processor and the set of installed memory modules.

What are the pitfalls?

In most cases – no, but some laptops with younger intel processors refuse to accept 16-gigabyte DDR3L memory modules, for them the maximum volume is limited to 8 GB per slot, so the only available option is 2 8 GB dies. Since we are talking about younger processors (i3, pentium, celeron) and their "energy-saving" versions – there is hardly a problem that will put a laptop with such stuffing in an inconvenient memory position (at a maximum 16 GB) Not by computing power.

The system says that I have 2 more memory slots, I opened the laptop – and the only available slots are occupied, what should I do?

There are not many options: either the manufacturer decided to save a couple of bucks and did not remove two additional connectors, and the BIOS is one for the entire line of laptops, or they are on the other side of the motherboard.

In the first case, a place for memory slots can be found nearby With the available two – in some service they can completely unfasten the missing elements, but here it is worth ten times to study the question, look at adjacent models and study the forums: maybe not only contact pads, but their binding as well.

Unusual location of the RAM slots on the Lenovo ThinkPad notebook.

In the second, look at the guides for disassembling your laptop on the network – or you will see a hatch under the keyboard With access to two connectors, or will have to remove the motherboard itself.

What about the compatibility of the already installed memory with the new one?

If you bought a module with the same frequencies as the one already available, there will be no problems. Laptop operating time rarely has non-standard timings, and JEDEC's stitched profiles have specific delays for each operating frequency. Only two processors can work with overclocker memory (the same 6820 and 7820HK), and in notebooks with such hardware usually 32 or 64 GB is out of the box – you probably will not need to upgrade in the near future.

It's all too complicated, I can not remember

Well, in this case, KVR16LS11 / 8 is very likely from DDR3, and for systems more recent, with DDR4 on board – KVR21S15D8 / 16. For complete certainty, you can use our master for the selection of compatible iron.

Summer – time for upgrade

As usual, we give our readers promotional codes – and if the dollar rate does not please you, then let this small discount make the cold summer a bit warmer.

As you remember, there is not much memory, and even mobile – even more so. Therefore, if you want to get hold of Kingston SO-DIMM (and we have a lot of useful and different), it can be done here.
