How to choose right RAM

[Kumar Nikhil]

I have 4GB DDR3 RAM and i want to upgrade to 8GB please tell me which one should I buy HIGH VOLTAGE RAM or a LOW VOLTAGE RAM and what is the difference between both of them

Kingston HyoerX-Beast is good ram aswell as Corsair Vengeance both good sets of ram

It depends on your pc configuration. Please post your complete system configuration.

i5 4210U
4GB RAM
2gb Nvidia 840M

that's a Laptop so you'd need SODIMM ram,

You'd be better off finding the manufacturer/model number of your laptop and then see if there are RAM compatibility lists for it.

We're not necesarily looking at voltage right now as much as how fast of ram your laptop will support.

use software like speccy or hwinfo etc to find out the type of ram installed. look for frequency/latency/timing
use the exactly same ram. its better to buy the same brand and model.

First of all u need to check if a free slot is available in ur pc for inserting ram ( obviously u must be having!)
Second, u need to check whether ur system supports which type of ram ie DDR3 or DDR2 or DDR as you know ur type u can skip this step.
third, use any software like RAMMon( just google it!), it will tell u about ur existing ram's latency, frequency etc.
fourth, compare this with the ram that ur going to buy. Make sure that u buy a 4gb ddr3 ram( better than buying two 2 gb ddr3 ram)
fifth, buy it!



Difference bet high vol and low vol ram

Computer RAM is generally chosen based on three key factors: Speed, Size and Price. As green computing increases in popularity, power draw (reported as voltage) is becoming an increasingly important specification.

"The majority of DDR3 RAM runs at 1.5V, but many performance models can run at voltages as high as 1.65V. Low voltage RAM, on the other hand, can run at voltages as low as 1.25V. In addition to simply consuming less power, RAM that runs at a lower voltage is also typically more stable since less voltage typically means less heat."
