Installing NVMe SSDs on Older Motherboards Why Install an NVMe SSD on an Older Motherboard? There are many reasons, but mainly a NVMe SSD has higher speeds than a SATA, and the price is similar. An NVMe SSD can reach 3500 MB / s, while a solid SATA state drive does not exceed 550 MB / s. Why not buy a new motherboard with NVMe support? The main reason is that a new motherboard involves very high costs. Even if you say, you find the cheap motherboard, you still have to spend money on DDR4 RAM, like that old one doesn't work anymore. You also have to change the processor, because that's the way it works. The increase in performance, on the other hand, will not be so great, because in the last 6-7 years there were not too many leaps in performance, but rather small steps. An NVMe SSD injects your new life into the old system! No component in this world increases your working speed in front of your PC, like an SSD, and more. [Read more...]

How to check the health of the battery? The role of a laptop is to be a laptop, and when we say portable we automatically think of the battery. This is why it is extremely important to know how to check battery health. The technology in recent years has evolved extremely fast, but it seems that the batteries have gone a little slower; Despite the larger capacities of the LIPO batteries, they have remained with the same number of Charge Cycle Count. Because of this the batteries of mobile devices tend to no longer retain the amount of energy they initially kept. Some say it's good to remove the battery from your laptop! If you are thinking about it, it would be a good idea to keep the battery in the charged drawer when using your laptop at home, and only plug the battery in when you are leaving and need mobility. Logically, you keep the float-type charging battery, which tends to keep the battery at a certain level. But the producers say that ... [Read more...]

Pure Wave UPS for the boiler and everything else

Pure Wave UPS for the boiler and everything else
5 (11) 100%

Only pure wave ups go for boilers and other inductive loads If you have a boiler, you have probably had at least one power failure once, and you have noticed that the boiler no longer works. At solid fuel boilers this becomes dangerous because the pumps which recirculates the heating agent stop and the boiler overheats the normal Ups, the computer ones such as this Mustek 2012 go very well with PCs, TVs, radios, etc., that is, everything has no engine. For boilers, refrigerators, air conditioners and others with motor, computer UPS's are not suitable. What do pure wave UPS have in addition? The pure wave UPSs for power stations have a special inverter that generates a pure sine wave, just like the one in the electricity supply network. Computer UPS's have a simulated wave, which can damage working devices. [Read more...]

How to connect a network hard disk with OpenMediaVault What is a NAS? The NAS comes from Netowork Atached Storage, which is a network-connected storage unit that can be accessed remotely, from the local network or from the Internet. What is a good network attached storage? Let's say we have an external hard disk, which can be connected via USB to the PC. It can only be accessed from a PC. If we want to connect it to another PC, we need to disconnect it and connect it to the other PC. A NAS can be accessed through the network by anyone who is connected; And with a forwarding port or a VPN server, we can access the NAS from anywhere in the world via the Internet. The difference between a dedicated NAS and Raspberry Pi. The difference between a Network Atached Storage and a Raspberry Pi with OpenMediaVault is small and depends on the hardware limitations of the Pi. On a dedicated nose we have connection on SATA, Gigabit LAN and supports for mounting multiple disks. The advantage in his favor ... [Read more...]

LAPTOP WITH STRICT SCREEN (black) - problem solving What we do when the laptop screen is broken and we can no longer use it. You probably think it's simple, you connect your laptop to an external monitor, right? The problem is that it does not work, or in the best case we can only use the shutdown system, without being able to make reinstallation or enter the bios. Problem Description! If the screen of a laptop is damaged, most of the time we cannot use an external monitor. And even if we can use an external monitor, we can't get into the bios and we can't do installation of opera systems. It's weird, as it should normally go. There are still happy cases. On some laptops you can automatically switch to an external monitor, if you close the lid of the laptop, if you press a certain key when starting it. Unfortunately, it seems to only work on older laptops, where the connection to an external monitor was made through a VGA (analog) connection. Why can't I use the external monitor ... [Read more...]

What is the state of the components of the PC How can we see how the components of the PC work and if they cope in certain situations. It is very difficult for a man to know how his PC feels, because he does not tell us when he "feels bad"; Just give up and you're ready. But we can prevent premature failure of components if we occasionally look at the operating parameters of the hardware. What are logs? Logs are reports written in a document, reports that contain the operating parameters of the components. Where do we get the logs? There are numerous applications on the market that can generate logs, applications that can log for any hardware parameter. For example, HWinfo is an application that makes the most detailed logs for the processor, memory, graphics, chipset, voltages, temperatures, etc. GPUZ is an application that generates logos related to the video card, just about everything you need to do with the video card.

Checking RAM with Memtest86 RAM is one of the most important components of the system, without which our computer would be much slower. Sometimes RAM can be corrupted, and unfortunately there is no warning system when it happens. Sometimes the operating system senses problems with RAM, but most of the time these problems go unnoticed and occur when the world is dearer to you; For example, in games, where RAM is heavily requested, we can receive a crash or simply an unexpected restart of the entire PC. Error-induced RAM verification Sometimes RAM problems resemble problems that some sources have, and so we can be easily misled. Also the error induces us the Windows utility, which should test the RAM, but can not do too well because while running Windows, it is partially loaded into RAM. Exactly how you should change the wheel while driving (this ... [Read more...]

Batteries are endless in our lives. From watches, to cars with remote control or flashes, all the devices need energy, which we extract from the ordinary batteries. The problem comes when we have so many batteries in the house that we no longer know which is charged and which is discharged. The multimeter is a tool that helps us to see how charged a battery is. Unfortunately, not everyone has a multimeter, or not everyone is willing to look for it / use it, just to check the batteries. The fastest method of detecting discharged batteries, was "lightly hitting them on the table" and observing the reaction. This method of checking the batteries really works, and there is no hint. How do we check discharged batteries without devices How do we check discharged batteries? On a slim, solid and stable surface, from 5 cm, we easily escaped the battery, in a controlled way. If the battery is light, it means that it is discharged, or used for a battery. [Read more...]
