How buy compatible additional RAM ?


I recently shared my

smart shopping experience

with you all in which I showed you how an item can have price difference of $5-$7 on various e-commerce platforms. I learned that while purchasing a RAM for my PC.


While buying an additional RAM for PC i.e. RAM for another slot I learnt various things which we should keep in mind while upgrading memory of our PC. In this short article I will tell what we should keep in mind while purchasing additional RAM ?


One thing you should remember that never ever use RAM more than 4GB on a 32-bit operating system. It is criminal waste of resources. If you want to use more than 4GB memory on your PC than you should use ONLY 64-bit Operating System.


First thing which you should find is how much amount of memory your motherboard can handle i.e. how much total amount of RAM is supported by your Motherboard. This can be either found from web site of your Motherboard company, by entering model number or by Manual which came with your motherboard.


Most of the motherboard at least support total of 8GB memory. That means you can either have a single RAM stick of 8GB or can use two 4GB RAM modules. Some of Motherboard go above 16GB which is more than enough.


Now come important things which we should check in an additional new RAM before purchasing it.


If you want to use two RAM sticks together than first of all note down the Frequency, Latency, Timing, Generation(DDR…) and even company of present RAM of your PC. We need to compare these things with the new RAM before purchasing it.


How to find frequency, latency, timing, generation and model number of my RAM ?


You can easily find all these specs of your RAM from website of your RAM manufacturer. You need to just enter model number of your RAM and entire details will be infront of you. Modelnumber of RAM is mostly written on the sticker sticked on the RAM, if you couldn’t find model number through sticker or box of your RAM then you can use CPU-Z program.


Just download CPU-Z and install in your PC. Run it and move to ‘Memory’ tab and note down the model number of your RAM. Now just point to Google and type model number of your RAM and press Enter key and find out Frequency, Latency, Generation and company of RAM.
Tip: You can also use various e-commerce sites to see the specs of your RAM.


Once you have got Frequency, Latency/Timing, Generation(DDR1,DDR2,DDR3…) and company of your present RAM, we just need to compare these with the additional RAM which you want to purchase.


Manufacturer of the RAM


This is less important factor which we should keep in mind when we want to purchase a compatible RAM but it is always suggested to try to purchase new RAM of company same as your current RAM. Though if manufacturer is not same it would be Okay but keep the same company as first priority.


RAM generation


RAM generation means the type of RAM like DDR1, DDR2 or DDR3. If current RAM in your PC is DDR2 then you might face problem while running it with a new DDR3 RAM. So try to keep generation of additional RAM same as current RAM else they might not work together.


RAM frequency


It is believed that higher the Frequency of RAM, higher the speed of RAM but try not to think the same way if you want to run additional RAM with current RAM of your PC. Doesn’t matter if your new RAM is of 1333 MHz but you won’t get that performance if you run it with 1066MHz RAM, your BIOS will automatically downgrade the frequency of RAM to same as the slowest RAM in your PC.


Now you might question that if Frequency can be automatically downgraded then why should I care for the frequency ?
Well, some RAM are just too stubborn, they just don’t want to go slow and sometimes few motherboard aren’t able to down the frequency of high frequency RAM to make it same as low frequency RAM thus you might get into a problem. So try to purchase additional new RAM of same frequnecy of current RAM of your PC else they won’t be able to work together.


Timing/Latency of RAM


In common man’s language RAM latency can be taken as time a RAM takes to interact. It is time it takes for transmission of data between CPU of computer and RAM. It has many sub-timings too but we won’t go too deep in it. Just make sure CAS latency and Timings of your new RAM is same as the RAM with which you gonna use it.


That’s it, these were some of the factors which you should take care of while purchasing a new additional RAM to run with old RAM of your PC. If most of these factors are in your favour, chances are high that the new RAM is compatible with old RAM of your PC, they can run together.


Now a simple question, Can a 2GB RAM work with 4GB or 1GB RAM can work with 2GB or so on… ?


Answer, which I got after some researching, is Yes!


So I wish you best of luck and hope that you will shop smartly while purchasing new RAM of your PC.
