Ram Speed & Timing Explained

Ram Speed & Timing Explained
A quick memory can be really useful for lots of things whether you're trying to find your way to a restaurant sing-along to that song at a karaoke or remember who won the presidential election in 1880 because you've got 50 bucks on the line at a trivia game something anyway, but what about having quick memory in your computer although knowing how much memory to put in your PC is usually pretty straightforward the topic of memory speed is more of a mystery, so how much then does it actually matter well let me explain.

It helps to know what those numbers on your memory modules mean similarly to your CPU all RAM or random access memory has a clock speed which corresponds to how much data throughput it can handle each second but in addition to clock speed memory also has timings which are typically expressed as a string of numbers like 9 9 9 24 these numbers are measures of latency which in this case is the number of those clock cycles per second that it takes for your RAM to do things like access certain pieces of data, so shorter timings will mean faster performance so together the clock speed and the timings will determine exactly how fast your RAM will operate and like with a CPU or a video card you can also overclock your RAM by optimizing the megahertz and giving it a little bit more voltage but unlike processor overclocking which typically gives small but noticeable performance gains getting the fastest memory possible for your system is often dismissed as a waste of money by many enthusiasts, but why would that be then I mean isn't faster always better when it comes to computer components, the short answer is yes but in the real world faster RAM typically will only give you very small performance boosts that you probably won't be able to notice unless you're using very specialized benchmarking software you see modern memory has lots of bandwidth and can often handle more data flowing in and out then many programs are anywhere near capable of using, so similarly to how you usually won't get more FPS in your games by plugging your graphics card into a faster PCI Express slot spending more money on top end memory won't usually translate to noticeable improvements in your programs but as with most things in the computer world there are exceptions to the rule and faster memory can be very useful in certain situations on the server side of things you can use it as a cache so you can take data that's on your main storage and make it so it can be accessed much much faster or you can use it for many many virtual computers all at the same time so even if each of them only requires a fraction of the bandwidth between them all they can use nearly limitless amounts of memory bandwidth that's called virtualization.

On the desktop side of things though the examples are fewer and further between but there definitely are some like for example if you're running one of AMD's APU processors because onboard graphics use your main system memory as video RAM unlike a discrete graphics card which has its own separate RAM on the board there's a lot more information going to and from your system memory when you're gaming.

So faster memory can give a real boost in your frame rates with that said if you aren't running an APU it's usually a better idea to focus your money on things other than raw speed when buying memory such as buying from a reputable brand with a good warranty because lower quality Ram can cause lots of inexplicable errors that can leave you tearing your hair out when you're trying to figure out what is wrong with your computer even buying RAM modules that fit in well with the rest of your computer is in my opinion a better idea than going for the highest possible speed.
