Mouse upscale iconic Raser, the Mamba has an update allowing it to benefit from the new 4G sensor manufacturer: program a dual laser technology / optical and precision 6400 dpi!
Design and Ergonomics [/ anchor]
No surprise, Razer Mamba does not revolutionize a design standpoint. The mouse features quite generous dimensions (maybe even a little too much for little hands) and is optimized only for the right hand. Razer had apparently he called left-handed players to express their interest for Mamba Left, but nothing concrete came out for a moment.
The grip of the mouse is affected by the thumb and the little finger parts: it is not likely to slip from your fingers during a game. Boxing mouse into the category average weight and 138 g, it is lighter than the Logitech G700 or the Gigabyte Ghost weighted.
As always with Razer, the wheel is notched, broad and precise, without moving horizontally however. Regarding the extra buttons, no change either: they are always 4 Two on the left side of the left mouse button, falling in the index, and two on the left edge, falling on the go.. Good point: they are large enough to not require contortion, and also benefit from a non-slip coating.
Skiing is impeccable, provided by three pads at the ends, and central pad around the sensor. Undoubtedly one of the most pleasant to handle than it has been in the hands mouse!
As the Naga Epic, the Mamba is a hybrid wired mouse / wireless: the cable to the mini-USB format can be connected to the recharging base, but also to the mouse itself. Be careful, however: the system hugs the shape of two-fixation devices, but it will be entirely impossible to connect a standard USB cable.
Small detail that kills the recharging base, like a mouse wheel are backlit and agree between them. Guaranteed when reloading effect: Mamba is also a beautiful object when not in use. Moreover, the exquisite taste of Razer welcomes you to the packaging of the mouse: a true work of art.

Drivers [/ anchor]
The Razer drivers are splendid and the Mamba obviously not an exception. The options are arranged in tabs with clear headings, and the look of the interface is simple enough to be readable.
Razer Mamba drivers buttons
All buttons can be configured to explicitly defined activities (sensitivity adjustment, scrolling, profile changes, activating a temporary "sensitivity" for delicate passages or snipe ...), or macros, with a comprehensive editor. It can record keystrokes with or without taking into account the length, insert specific delays between individual actions, or a single delay between each action.
Razer Mamba drivers macros
The mouse can have configured with five different profiles stored on its internal memory. Side performance tuning, so you can adjust the sensitivity up to five levels of 6400 dpi and change the take-off distance, which allows you to set how distance between the sensor and the surface (mm) mouse have disconnected. This feature has designed for players making long movements requiring repositioning of the mouse on the pad. The range may be set manually or automatically based on the detection of the surface used. The reporting rate can be lowered to 125 or 500 Hz or kept at its maximum level of 1 MHz.
Razer Mamba pilot performance
Sensitivity can be set independently for the X axis while it can set different sensitivity levels of 5 (again with an X and Y separation possible).
As for the Naga Epic, we can adjust the lighting, which is limited to the mouse wheel on the Mamba, and opt for a fixed color or color cycle, with a full range of choice in Windows. The light level can has adjusted. Finally, we find the same options of power management on the Naga Epic: light reduction in wireless mode, standby after a period of inactivity and flashing wheel below a certain level of battery.
To use [/ anchor]
What about the Mamba in use. Otherwise, it is an excellent precision in wireless mode as wireframe? The response time of the mouse is one ms, and we have not seen disconnection during use in wireless mode. However, it could be quite greedy: count ten hours of battery life.
Innovations 4G sensor honestly they are needed to have an advantage in the game? Frankly, the performance of the Mamba already seem quite sufficient: the response time and the reporting rate are at the top, and the difference between 5600 and 6400 dpi is not sensible. Nevertheless, we imagine that it will make a difference for some "PGM".
Conclusion [/ anchor]
Razer Mamba mouse is undeniably real, but the manufacturer is paying a high price: 129 euros (RRP). Ergonomics is very satisfactory, except perhaps the placement of buttons to the left of the button ... left, not necessarily comfortable to reach with the index. Precision is the appointment, and if the 4G sensor inputs in terms of sensitivity are not obvious, setting off distance can be a plus. We also appreciate, as the Naga Epic, the use of a wired / wireless hybrid mode, even if the receiver / charging base is certainly very stylish, but a bit bulky. Finally, a quality mouse, but will not suit all budgets.
To watch a movie in peace or to listen to something on an MP3 player, we will not use the same headset. Everything you need to know to choose THE best headset.
There are of several types:
For wired headsets, several models:
Three possibilities:
There are also in-ear wireless technology including Kleer, which ensures high sound quality.
General and technical aspects
material
The material headset operates on two levels: comfort and audio transmission. For in-ear tips, several materials and forms: they may be silicone, foam, rubber, biplanes (two fins) or triangles (with three blades).
Cord length
For outdoor use, a wire around 1 20m is a minimum. For the interior, to connect the headphones to the TV screen, several meters are preferred.
connector
For headsets and wired headset, two things to consider:
technical aspects
Frequency Response
Also called bandwidth, more frequency range covered is wider, your helmet will be capable of reproducing the diversity of sounds.
It is being expressed in Hz and kHz. For example, a headset with a frequency range of 20 Hz to 20 kHz (or 20 000 Hz) is excellent.
sensitivity
Also called sound pressure is being expressed in dB (decibel). The higher it is, the sound is being restored and, therefore, more headphones are quality (beyond 100 dB for example).
sound insulation
Sometimes indicated, it is being expressed in dB. Proper insulation prevents sound disperses: listening is better. In general, it is about - 26 dB, for good headphones.
Basses
It must look at the matter magnets. A neodymium magnet reproduces more bass and power. Some headsets and headphones have specific components, such as a metal layer, which prevent vibration low.
Helmet opening
Closed warranty usually an excellent bass response. Good for helmets lounge.
Opened.
Semi-open: a suitable alternative.
The impedance is being expressed in ohms, resistor unit, and reflects the acoustic resistance of the device.
Helmets are living up to hundreds of ohms. For a player, although less powerful, it is not worth to exceed 100 ohms (less than 50 is even sufficient). Must sound source is a great power if we want to have a good listening on headphones with high impedance.
headphones
There are of several types:
- Atria: Classic headphones
- Headphones "clips" they attach to the ear and provide excellent support.
- ITE: these headphones are adapted to the ear canal. The music comes deeper into the ear for better sound quality. Good resistance which avoids having put the headphones they are usually sold with several sizes of ear, to find those that best fit your ear.
- Semi-ITE: a good alternative for people who experience discomfort with ITE.
The headphones
For wired headsets, several models:
- Lightweight headphones: classic, it passes overhead.
- Neckband Headphones Recommended for athletes provides enough support.
- Earphones: mixed system of arch headphones and in-ear headphones.
The wireless headset
Three possibilities:
- The headset is connected to the carrier via Bluetooth.
- The headset is being connected by infrared (headphones salon).
- Headphones connected by RF technology, radio frequency.
There are also in-ear wireless technology including Kleer, which ensures high sound quality.

For headsets and wired headset, two things to consider:

- Matter of decision: a gold-plated jack ensures excellent audio transmission.

That it is of a desktop machine or a portable PC, the memory exploits a big role the performances. With what does serve the memory as a computer, how to make it evolve/move and choose it? We inform you on the Type of memory in your computer and my of course on this guide…
Type of memory in my computer
The random access memory is used by the processor in order to carry out calculations effectively: the programs are partly charged with the hard drive to the memory because the latter makes it possible to work much more quickly. When the memory size is insufficient, the treatments are done either on the memory but on the hard drive and they become very slow then.
You do not deprive of memory!
The computers currently in sales have 2 Go of memory, which is enough in the majority to the uses. For a greedier use, the such video games, 3 or 4 Go of memory will be preferable.

Format and standard
Technology evolving/moving, the formats of the memories passed from the SDRAM, GDR, DDR2 with the DDR3. The format to be used is dictated by the mother chart, it is thus necessary to refer to it to know which type of memory you can use. The DDR2 still is very much used on the machines entered and average of range whereas the DDR3 is now quite present on the top-of-the-range computers.
DDR2 800, DDR3 1333…
Each format of memory is followed several evolutions of standard impacting mainly their performances. Indeed, these evolutions are done mainly on the frequency to which the memory is able to function. For example, memory DDR3 1800 (1800 MHz) is more recent is faster than the DDR3 1333 (1333 MHz).
The news memories not being forcing more expensive than the old ones, it is sometimes judicious to choose this one: he who can do more can do less.
In theory, the new standards are retro-compatible and can thus function on a mother chart envisaged at the base for frequencies less: the memory will function simply at the frequency imposed by the mother chart.
Memory GDR
Memory DDR2
Memory DDR3
The number of bar
You can install only one bar memory on your mother chart: it goes and it is the most economic solution. It is thus to privilege for an office automation machine line entry. But if you wish to profit from better performances, it will be necessary to see larger.
The number of site for the bars memories on a mother chart varies from 1 to 6:
1: often available on the mother charts minis-ITX
2: the installation of one or 2 bars allows, with a weak margin of evolutionarity (see large from the beginning)
4: the installation of a bar or one or two pairs allows, which leaves a margin of evolution
6: allows the installation of a bar or one or two pack of 3 bars memories.
The current mother charts make it possible to make function the bars memories in mode Dual Chanel: instead of a bar memory, you must install two strictly identical. Thus, you profit from a profit of band-width (higher flow). Chanel Triple also exists on certain configurations Core i7 or professional. In both cases, specific batches of memories are available.
