How to expand the RAM of the Synology DS1515?

Many NAS from Synology, and especially in certain ranges, they have the possibility to expand their RAM, even if it’s not particularly supported. One of the differences between two models such as the DS1515 and the DS1515+ is that the second one supports up to 6 GB of RAM through an accessible SODIMM slot on one of its sides.

The DS1515 comes with 2 GB of RAM, an interesting amount for a NAS. The best part is that the 2 GB of 1600 DDR3 RAM are mounted on a SODIMM slot. We can mount up to 4 GB of 1600 DDR3 in this slot as long as they are low voltage, therefore 1.35 modules. The only difficulty is that we need to gain space between the NAS’s motherboard and the storage slots so that we can extract the old module and install the new one. Unmounting it will oblige us to almost unmounts the whole NAS, because of the connection “riser’s”, so it’s best to just make some space to be able to unblock the installed DIMM and replace it for a new one.


How to create a restoration point in Windows 10

The restoration tool in Windows 10 has become a great ally for those who like adventure and want to be the first to try everything, and therefore they don’t hesitate to install unofficial builds and participate in the fast ring channel.

Many of these users are usually advanced and generally know what they do, but since Windows 10 has reached enormous popularity and the huge number of testers is also characterized by variety, we thought it would be interesting to post this short tutorial, in which you will see how to create restoration points in Windows 10.


Neutral dynamic DNS Client for Android

Many of us have DNS registry services that offer free dynamic DNS services and therefore we have to rely on services like no-ip, dynDNS, etc. Today I will introduce you a neutral app and show you how to use it.

The application in question is: Dynamic DNS client. You can download it from the Play Store and it is completely free! One of its advantages is that it doesn’t depend on any particular service, it doesn’t require root and it is capable of updating through Wi-Fi or 3G/4G, making it quite versatile.


How to clean your computer from Spyware and Malware

Many modern security suites incorporate basic protection against non-viral threats such as rootkits and spyware. But the specialized solutions are still a better option to fight them. Whatever your case is, learn how to use this antimalware and antispyware tools.

1. Download the tools

Probably you already know about the Spybot: Search and Destroy Tool since it has been recommended to remove adware from your PC for years now.


How to test your internet service connection speed

You have hired a high-speed internet service that offers so many megas or a mobile data connection that promises the fastest 4g service in the market.

Does the real speed connection of our internet service comes close to what you actually picked? With honorable exceptions, probably not. The internet provider is careful not to mention that the speed advertised is the max speed and that the real speed connection depends on many factors (i.e. area where you live, whether its fiber or cooper, network congestion, signal reception, your internal configuration, and so on.).

Speed test

Since there can be plenty of situations, as users we can at least know what is our actual speed and compare it to the internet speed you picked.

Novice users tend to use the direct file download speed or peer to peer connection speed from your internet service. It can be an estimate but we cannot really rely on this kind of measures because it is up to remote’s server bandwidth, its congestion state, routing loop until it reaches our computer, etc.

Test Speed

In the previous image we can see the speed of downloading the latest test version of Windows 10. Even though Microsoft serves a brutal bandwidth (best in the market), we didn’t get to make the most out of the connection (ONO 60/6 in this case). We could improve it making use of specific software for direct downloads but in any case we cannot rely on this kind of measures for knowing our connection speed.


Instead, we can use online tools which offer more accurate measurements. One of the most popular and easiest to use is, as you will find out.

  • We just need to open their website in our browser and we will see how the tool offers us our public IP address, location and internet provider.
  • To begin the test we just need to make a simple click, having the option to choose the server from which we want to make the test. In general, the closest server will give the best results.
  • The tool will return the max download and upload speed reached and the ping.
  • The result will be available and we have the option to make a screenshot of it, to compare with future tests or to include it in our forum profile.

Some considerations

  • In order to achieve maximum speed, you should use a wired Ethernet connection on the computer closest to the router.
  • If you have multiple routers or access points connected, unplug them so that you can make tests on the man router.
  • Avoid this or other PCs in the network to make use of the bandwidth for other services such as P2P since this can affect the test.
  • Also for Wireless network testing. The differences here can be even higher depending on the terminals, location, wireless standard being used, channel it’s connected to. Try finding a channel that is not too saturated.
  • The same is true for mobile broadband network tests. Ideally, you should locate a clear location with a good provider signal. The Speedtest mobile app is free for iOS, Android and Windows phone. Also, it supports LTE, 4G, 3G, EDGE and EVDO networks.
  • It performs several measurements in order to obtain an average at different points of the day. The differences you will get may surprise you.

How to run Windows 10 from a USB flash drive

This actually could also be applied too to Windows 8 or Windows 8.1 but it’s certainly more interesting and more challenging to do it with Windows 10. The process requires a USB flash drive with at least 8GB, though I wouldn’t mount it if we are going to use it for real in less than 16GB, as this must always be done in USB 3.0 USB flash drive with acceptable speeds.

The first thing you need is an already functional Windows 10, as the “bcdboot” command that we will use in one of the last steps required needs to be Windows 10 version of to generate the dunk images for the Windows 10 boot. You can virtualize it or use any of the piece methods that we have tried here in this section. You must also have an ISO installation of Windows 10. You can find it in the Windows 10 Insider program.


Control the number of Chrome tabs to limit the use of RAM

Any modern Operating System works well with 1 or 2 gigabytes of RAM. The problem is when the most common tool used in a computer – generally being the browser – takes control and saturates our system, especially in hogging all the RAM. Modern browsers use “sandbox” systems to isolate processes and to protect themselves and our systems, leading to a lot of RAM consumption.


This trick is specially recommended for computers with 1 to 4 gigs of RAM, where we want to keep an eye on our browsers RAM consumption. This way we will saturate it less and we won’t have to manually take care of it every time.


Upgrade Windows 7 or 8.1 to Windows 10 from the Windows Update

If you would like to upgrade your Windows 7 or Windows 8 to the newest Windows 10 but the previous installation option seemed too complicated, this is for you. This is the easiest and safest way to install Windows. Right from the Windows O.S, using the Windows Update option.

1: Before installing Windows 10

Normally, if you wanted to try any of the Windows versions prior to their official release, you needed to download the ISO file from Microsoft’s website and then create an installation disk in order to install the new Windows onto your PC.

This is now a thing of the past for Microsoft.


How to correctly apply thermal paste

Thermal paste (also called thermal silicone or thermal putty) is a substance that improves the conduction of heat between the surfaces of two or more objects that may be irregular or not be in direct contact. Thermal paste is used to join (paste, in a way) the processor with the base of the heat sink, improving the passage of heat from the processor to the heat sink to dissipate the heat generated by the CPU. Application of thermal paste isn’t at all difficult, but we have to be careful; if we use too much, we might achieve the opposite of the desired effect and end up raising the CPU’s temperature. So be patient and be careful.


Before beginning, let’s clarify a few terms to ensure that we apply the thermal paste in a determined manner.

  • IHS: Integrated heat spreader. A small metallic sheet that covers the processor, this mainly protects the
  • DIE: The most internal part of a processor. Basically, it’s the processor in and of itself where you’ll find all the cores, memory, cache, etc.
  • PCB: The base plate of any component. For example, the base plate that holds all the components of the graphics card. May be green, blue, black, and so on.

What is thermal paste, really? And why is it necessary?

The IHS of current processors isn’t 100% smooth and without malformations, and neither is the base of heat sinks; thus, if the IHS and the base of the heat sink aren’t in complete contact, heat can’t get to the heat sink and the temperature of the processor will increase. For this reason we need thermal paste, which better units the processor and the base of the heat sink, getting around any malformations or irregularities that either may have.


How to activate the silence button in Google Chrome

If you’re a regular user of Google Chrome, you’ve surely noticed that when a website has audio, the speaker icon appears on the tab. Although it is a practical function by default, today we show you a trick to transform the icon into a button that will allow us to silence any website without the necessity of third-party plugins and in less than a minute.

The first we have to do is access the experimental features of Google Chrome by typing chrome://flags/ in the navigation bar (also known as Omnibar). As always, we recommend you to be careful with the options that appear because the activation of some may cause the browser to show errors or stop working. To activate the mute feature we have to go to “Enable Tab Audio Muting UI control” and click the Enable button.


After restarting the browser, try to enter any website with audio or video and you’ll see you can now click the speaker icon to deactivate sound. Of course, you can disable this feature at any time by accessing the experimental features menu and selecting disable.
