Everything you need to know about upgrading your RAM

Everything you need to know about upgrading your RAM

Many PC owners won't necessarily need to ever update their RAM. But if one day you decide to, you might understandably make the assumption that adding faster and larger amounts of memory will allow your games and other applications to run faster.

However, perhaps surprisingly, that's not always the case. And that's exactly what we're looking in to here.

The memory landscape

Computer memory is divided into two main types: DDR3 and DDR4. The former is older, having debuted back in 2007, while the latter only hit the mainstream recently, with Intel's X99 platform in 2014.

They both work using the same principle: flash chips store data that the computer needs immediately, but it's lost when it's no longer useful or your PC is turned off.

It's governed by several common attributes: larger amounts mean more data can be stored, and higher MHz ratings mean memory runs at a faster speed, so data moves in and out quicker.

Different locations of the key notch (on the insertion edge of each DIMM) prevents a DDR3 (top) or DDR4 stick (bottom) from being installed into an incompatible board or platform

The newer standard, DDR4, has several advantages over DDR3. It runs at a higher frequency, so it's able to process your tasks at a faster rate. DDR3 is generally clocked between 1,333MHz and 2,400MHz, while DDR4 ranges from 2,400MHz to 3,200MHz.

It's possible to blur these lines with overclocking (forcing the processor to go at a faster speed), but, for the most part, DDR4 is faster. It balances those better speeds with chips have double the internal memory banks, faster burst access and higher data transfer rates.

DDR3 and DDR4 memory work with different motherboards and chipsets. Essentially, DDR3 is compatible with almost every motherboard and socket out there, but DDR4 is only compatible with boards using Intel's X99 chipset and LGA 2011 processor socket.

DDR4, however, does have a downside – increased latency (the time it might take to perform a task). Newer DDR4 2,133MHz memory has a latency rating of CL15, which means it'll take 14.06ns to perform a read, while DDR3 1,600MHz memory reads at 13.75ns.

That's a tiny margin, and DDR4 negates this disadvantage with its generally higher clock speeds. Nevertheless, if you'd like to keep an eye out, look for CAS ratings. This indicates latency, and lower is better. No matter which memory you buy, you'll have to deal with channels.

Dual-and quad-channel setups are the most popular and improve performance by allowing motherboards to use multiple channels to send and receive data simultaneously, therefore improving bandwidth. It's possible to run memory in single-channel mode, but there'll be a performance decrease if you run a single stick of memory rather than two or four.

The changing PC landscape

The variety of different specifications means that prices vary wildly. The cheapest 16GB DDR3 kits made from two 8GB sticks currently cost about £65 ($90, AU$130), but the most expensive can cost more than £200 ($279, AU$400).

It's a similar story with DDR4, which dual- and quad-channel kits also vary by huge amounts when it comes to price.

But these will always be more expensive than their DDR3 equivalents. Manufacturers claim that the increased speeds and better features provided by pricier memory will make a dramatic difference to performance. But we're not so sure, so we've set up some test rigs to try and find out just how much memory you really need.

Both of the test rigs we've set up use MSI motherboards. One uses Intel's Z79 chipset with a Core i7-4770K processor, while the other is an X99 PC with a Core i7-5820K chip. Both use operating systems installed on a Samsung 850 Evo SSD, and both use an Nvidia GeForce GTX 980 graphics card.

We've already mentioned the different processors and chipsets that work with DDR3 and DDR4, but there's more to choosing your components than just making sure your new gear is compatible on paper. Intel's Haswell architecture is behind the bulk of its current desktop processors, and it was its first to include native support for dual-channel memory, with up to 32GB of RAM.

It's used for chips that range from cheap Celerons and Pentiums to expensive Core i5s and i7s, and these desktop Haswell chips all plug in to the LGA1150 socket. The LGA 1151 socket is also DDR4-compatible.

Most Haswell-based processors are deployed with mobos that have Intel's H87, Z97 and Z87 chipsets. When it comes to memory support, they're all impressive. They handle four slots that accommodate two sets of dual-channel memory, and most full-size ATX boards also support 32GB or 64GB of memory at rapid speeds.

The X99 chipset introduced DDR4 to the (high-end) mainstream market, bringing with it faster clock speeds and better power efficiency, but with increased latency

Support for faster memory

Intel has further developed its CPU architecture with Haswell-E. Processors that use this system also use the LGA2011 socket and X99 chipset, which means that support for DDR4 is included – and so, in turn, that means integrated support for faster quad-channel memory when compared to DDR3.

AMD's processors and APUs, meanwhile, use the Piledriver architecture. Its own memory controller was given a speed boost over the previous generation of AMD hardware, but memory support ultimately still isn't as good on this side of the fence. All of AMD's current chips support DDR3 memory, however, some of them are restricted to 1,600MHz or 1,866MHz memory, while only a handful top out at 2,133MHz.

Like Intel, these boards do support dual-channel memory. Processors and chipsets aren't the only bits of your PC that need to be checked before shelling out for new memory – motherboards are also vital. You'll need to make sure a board has the right number of slots.

You'll also need to check what amount and speed of memory it can accept: it's no good dropping a few hundred bucks on a 32GB 3,000MHz kit if your motherboard only goes to 16GB and 2,666MHz.

There are nuances to be examined, then, but for the most part, the memory landscape is heartening. No matter what processor, chipset or motherboard you use, you'll be able to equip a PC with plenty of high-end memory at decent speeds. That's good for anyone wanting to upgrade parts of their PC, but it's not necessarily great news for companies that rely on flogging expensive, high-end kits.

Future developments from Intel and AMD will only improve the situation. Intel's latest architecture, Skylake, will support DDR4 across all of its full-fat desktop chips, but it'll also be backward-compatible with DDR3, which adds a huge amount of versatility. We also expect to see improvements to the memory controller and support for larger amounts of memory running at faster speeds.

AMD isn't standing still, either. Its next proper desktop architecture is called Zen, and it'll offer full DDR4 support to bring the company's chips alongside Intel.

The first set of DDR3 benchmarks we locked and loaded were PCMark 8's Home, Creative, and Work tests – a trio of suites that simulate the kind of low-intensity tasks that take place on many systems, from web browsing and video chatting to word processing and spreadsheets.

How To Pick A Lock Using Hairpins

How To Pick A Lock Using Hairpins.

While lock picking is often a task attributed to thieves and burglars, it can actually be a really useful skill to learn for situations like getting locked out of your house, or maybe your safe. Once you start to understand how a lock works, you can begin to learn how to break into one. All you will need to pick a lock is a few hairpins or bobby pins, which you will modify slightly. If you don’t have any of these lying around you could pick yourself up a lock pick set off Amazon for pretty cheap here. The video below will go into a lot more detail on how to pick a lock, so be sure to check it out. The concept that this method is based off is that of applying constant rotational pressure to the tumbler, so that as you pick one pin, it will stay in the unlocked position. All you have to do is simply go down the line of pins and push up on the one that is currently stuck. You will be able to tell by how much force it takes to lift a pin, which one to push up on next. Once a pin is picked, you will hear a clicking noise signaling for you to move to another pin. Be sure to keep constant rotational pressure on the lock, because if you don’t, then the pins will spring back down and you will have to start over again. I tried doing this myself, and without a practice see-through lock, it took a lot of work, but I finally got a door open. It would be much easier to learn how to do this on the demonstration lock shown in the video, but it can be done with a little bit of patience. Don’t go getting yourself in trouble, though.

Lips, Red Naturally 

Have pink lips naturally without lipstick can add beauty and conjointly increase confidence in ladies, especially teenagers and adults. Pink lips, but can look nicer too will create men a lot of affected. Besides which ladies need black or pale lips? 
There is a presumption that the black square measure feminine smokers, but there is conjointly a black lips, but she was not a smoker. Well the opinions of the different.. Only she is aware of. Let's return to the article we have a tendency to can discuss, soft lips pink is a foregone conclusion in craved by each lady, it will cause you to look a lot of lovely smile. Factors that cause dark are typically caused by too abundant low, sunlight, smoking and improper care. 

According to Dr. Debby anti -Aging drugs Specialist graduate of Paris, France factors that cause black, among others:

Chemicals, such as the utilization of cosmetics that don't fit, allergies or allergy drugs dentifrice. For example on lip use of lipstick that not fit with our lips. 
Incompatible materials contained in lipstick when used in the long run will modification the colour of become blackened.

How to Destroying Stubborn Belly Fat

How to Destroying Stubborn Belly Fat.

Belly Fat

Persistent paunch fat has a tendency to be the last fat that goes. Losing stomach fat can be the hardest thing, since it can't be overcome by activity as it were. There are a few propensities that you should embrace in the event that you need to dispose of the resolved gut fat.
On the off chance that your objective is a destroyed 6 pack here are 5 tips to help you overcome your objective:

DIET:

Diet

 With a specific end goal to lose the midsection fat you need to dial in your eating routine first. Expend less sugar and attempt to truly get your day by day starches from complex carbs. Extraordinary decisions are chestnut rice, sweet potato and oats.
Ensure that you hit your macros. Eating not so much protein but rather more starches is a formula for catastrophe. Make your eating regimen brimming with filaments and proteins. It has been demonstrated that a man devouring more proteins and filaments will have less muscle to fat quotients. Eating healthy, and arranging your eating routine viably, will help you lose gut fat at a speedier rate. In this way, the time has come to cut the carbs and include proteins in your dinners.

How To Build Self-Discipline

How To Build Self-Discipline step by step. 

Self  Discipline

Discipline is freedom. You may afflict this statement, and if you do you're under no circumstances alone. For many individuals discipline could be a dirty word that's equated with the absence of freedom. In fact the other is true. As Stephen R. Covey once wrote, “the undisciplined are slaves to moods, appetites and passions”. And in the long term, the undisciplined lack the freedom that comes with possessing particular skills and talents – e.g. to play a musical instrument or speak a far off language.
Self-control includes acting as per what you consider rather how you feel at the time. Regularly it includes yielding the delight and excite existing apart from everything else for what is important most in life. In this manner it is self-restraint that drives you to:

Take a shot at a thought or venture after the underlying surge of eagerness has blurred away

Go to the rec center when all you need to do is lie on the lounge chair and sit in front of the TV

Wake right on time to take a shot at yourself

Say "no" when enticed to break your eating routine

Just check your email a couple of times each day at specific times
In the past self-restraint has been a shortcoming of mine, and thus today I end up without the capacity to do various things which I might want – e.g. to play the guitar. In any case, I have enhanced, and I can say that it is self-restraint that got me out of bed toward the beginning of today at 5am to run and after that keep in touch with this article. Trust me, I would love to be nestled into bed at this moment, however this longing is subordinated by my inward feeling of reason.
In the event that you battle with self-control, the uplifting news is that it can be produced. For instance, it is just in the previous two years that I have prepared myself to wake early. The accompanying are what I have observed to be the five qualities of self-control:

How to Boost Your Metabolism

Boost Your Metabolism.

Lose weight faster by tricking your body into burning more calories—with less effort.

Fanning the flame:

You may have inherited your mom's slow-mo metabolism, but you’re not stuck with it. New research shows you can trick your body into burning calories more efficiently, especially if you hit the gym. By strength-training just a couple of times a week, for example, you’ll reverse 50% of the seemingly inevitable metabolism slow-down that comes with age, says Gary Hunter, PhD, a professor of human studies at the University of Alabama at Birmingham. So take control of your metabolism by making these boosters part of your routine—and (finally) stop sweating every cookie.

Kick it up a notch:

Running

The next time you run, swim, or even walk, ramp up the intensity for 30-second intervals, returning to your normal speed afterward. Using this strategy will help you consume more oxygen and make your cell powerhouses, the mitochondria, work harder to burn energy, explains Mark Hyman, MD, an integrative and functional medicine specialist in private practice in Lenox, Massachusetts, and author of Ultrametabolism: The Simple Plan for Automatic Weight Loss. "You increase the number of mitochondria and how efficiently they burn throughout the day," he explains.This way, you can exercise for less time than it takes to plod along at the same pace and still get great results.

Here's how to do it: Exercise for 5 minutes at 3.5 mph. Increase your speed to 4 mph for 60 seconds. Then go back down to 3.5 mph for 90 seconds. Repeat the entire sequence 5 times, twice a week. (To get a more challenging workout, increase the incline or your pace.)
