Relevant Functionality Monitoring In Memory Entry Mode Press Releases

Fix computer memory common failure

1, Judge and deal with the failure

As the memory of improper installation or have serious quality problems often lead to boot “memory alarm”, is one of the most common faults of memory. At boot time, have not heard the usual “beep” is heard, but the “tick, tick, tick …” ringing off the hook, and no image display monitors.

This failure most of the time because the computer’s use of the environment is not good, excessive humidity, prolonged use, the memory of the finger surface oxidation, resulting in memory and memory slots cheat the contact resistance increases, hindering the passage of current lead to memory self-test error.

Such memory failures are quite obvious, and very easy to re-install or replace by another memory to be recognized and addressed. After removing the memory, attention should be careful with ethanol and rubber finger will be cleaned on both sides of the memory, but not touched with bare hands cheat, because the hands will be attached to the finger sweat, in use for some time cause oxidation cheat again, repeating the same failure, the installation can be more memory slots for a few.

In addition, we also applied the hair brush in the NIKON en-el9 battery memory slot clean out the dust, then use a relatively hard and clean white paper folded into the memory slot to move through this method to insert the paper to the memory The metal tank wipe clean, then install the memory. At the same time to carefully observe whether the chip is burned, damaged circuit board traces. In addition some of the old memory (such as EDO RAM), must be installed in pairs. The Rambus memory must be on the motherboard to the memory slots filled to normal use, if not filled, you need to use a shape similar to the dedicated and Rambus’ series device “inserted in the free slot.

Poor quality or damaged due to the memory of system instability caused by fault, the computer repair process, encountered the most problems. Such as the system frequently appear “basket screen of death” and “registry corrupted” error or Windows often automatically enter the secure mode.

Such as encountered in “registry error”, we can enter safe mode, run by typing “MSCONFIG” command, the “Start” key in ScanRegistry front “V” to remove, and then restart the computer.

If the troubleshooting, indicating that the problem is really caused by the registry errors; If the problem persists, you can conclude that the machine is basically a problem of memory, then need to use substitution, put a good memory test performance, the existence of The same failure. Sometimes, for a long time does not defragment the disk, no error checking, it will also cause system errors and prompt registry errors, but for the prohibition of such problems run “ScanRegistry”, the system can run, but the speed will significantly slower.

]]>

To solve such a failure in addition to replace the memory, you can also try adjusting the motherboard BIOS in memory-related parameters. If the memory is less than the quality setting in the BIOS of the target, the memory will work in the non-steady state, the proposed one by one in BIOS lower CAS, RAS and other parameters to set values. If your memory is not a brand-name quality products, the best choice for the default setting for the “SPD”, or “auto-detect mode.” In the Dell Studio 1555 Battery SPD mode, the system automatically from the SPD chip memory access to information, so in theory, working memory at this time is the most stable state.

In most of the memory synchronous mode, the memory speed and CPU FSB is the same. But now, many motherboards support “asynchronous memory speeds,” that the two operating frequencies can be some difference. The typical VIA KT333 motherboard, for example, to enter the BIOS to find the “DRAM Clock (memory clock)” option, that is “Host Clock (bus frequency and memory frequency synchronization), Hclk-33M (bus frequency by 33M), Hclk +33 M (bus frequency plus 33M) and other three models if the memory is job insecurity, of course you can set the memory operating speed was lower.

2 Compatibility fault handling

Memory is the easiest computer to upgrade one of the accessories. Since we are using the computer is manufactured by different manufacturers of products together, the incompatibility as a user of the most concern. Because the upgrade properly, will result in system instability, memory not fully recognized, or even start a series of failures.

During the upgrade process, often mixed into memory problems, one of which is because the single and double-sided memory mixed into the result. Double-sided memory often take up two “BANK”, and some older models of the board there may be compatibility issues (such as INTEL’s LX/BX/810/815 old motherboard), it only recognizes half the capacity. On single-, double-sided understanding of memory would also like to say a few words, in fact, they are not good or bad in itself, the difference is very small, but the most important thing is to see which packages are better supported by the motherboard chipset. Undeniable is that the same amount of memory, double-sided than the higher degree of integration, depends on production date, after working together so nothing is more stable.

In addition we are very concerned about the two different specifications of the memory is able to use the same board, in fact, different manufacturers, different models, different speeds of memory can be used together, but the stability of the system have an impact, in particular, will will affect the overclocking performance. So the user to use two or more of memory, you should try to choose the same brand and model of the product, so you can maximize avoid the phenomenon of memory is not compatible. If you can not buy the original memory of the same product, the market should be adopted in good word of mouth brand memory, they generally have been strictly a special match and compatibility testing, component, design and quality can be achieved or exceed industry standards. Of course, not all brands have a good memory compatibility.

Again, use the CANON nb-2lh battery BIOS on the motherboard should pay attention to the memory parameters can be set too conservative, such as DDR266 and DDR400 memory, the memory of mixed cases, the parameters of the memory requirements set by DDR266, while SPD function should be disabled to avoid confusion.

In addition, we often talk about “dual-channel memory” is actually a motherboard chipset technology, with the memory itself is not much relationship. Currently there are nVIDIA’s nForce2 and Intel i865/i875 chipset supports dual channel and other technology. To achieve the i865/i875 motherboard dual channel memory technology, specifications and capacity necessary to use two or four identical memory. Only in strict accordance with DIMM1 +2 (board only two memory slots), DIMM1 +3, DIMM2 +4 and DIMM1 +2 +3 +4 four memory installation, in order to build dual-channel mode. In the nForce2 motherboards on the formation of dual-channel memory mode, and even the type of memory capacity, and there is no strict requirement to use two or three memory can be, as long as memory is inserted in DIMM1, DIMM2, DIMM3 inserted anywhere in a or two memory may apply to open a dual-channel. Easy to use. In the establishment of a dual-channel mode, we can start to see the BIOS information in the identity of dual channel memory.

Dell Ultrasharp U2711 Monitor Review

Dell’s UltraSharp U2711 is among the most expensive monitors review at www.techtist.com and two of the best performing monitors we have seen; but at ,049, its price will be prohibitive to some buyers.

The 27-inch Dell UltraSharp U2711 is a lot like a larger version of the U2410 Dell launched a few weeks ago – in fact, is larger than 3 inches, at least for the screen. Like the U2410, the U2711 has a matt black chassis with a touch of gray light that passes through the center of the panel. The panel is 1.75 inches deep, however, the back of the screen – which houses the backlight, connection options and ventilation system – extends another 1.5 inches, which the depth of full-screen monitor to about 3.4 inches. The width of the panel measures 25.4 inches long and the surface of the screen itself is a bit dull, matte and smooth. The bezel measures 0.8 inches long everywhere.

His foot rectangular pedestal measures about 12.5 inches wide by 7.8 inches deep. When called to the sides, U2711 swayed more than the U2410 did. In the U2410, Wade was virtually nonexistent. With the altitude of the screen at its lowest level, the distance from the bottom of the bevel on the desktop 1. 7 inches, and at its highest is 5.1 inches. The panel rotates about 70 degrees to the left and right and tilts 25 degrees backward. The panel can be unscrewed and VESA mount support (style) on the wall. Unfortunately, no portrait mode, unlike the U2410.

]]>

Dell includes a plethora of video options for U2711, all located in the back, such as VGA, HDMI, DisplayPort, Component, Composite, and two DVI ports. S-Video is the only link is missing, originally included in the 2408WFP. Also included are two downstream USB ports, an upstream port, an audio output port and a port of the speakers. Access to these connections was quite easy, we are only hampered by the lack of a pivot function in the monitor. On the left side panel intermediate two additional USB ports and a port card reader supports xD-Picture Card, MultiMediaCard, Secure Digital and Sony Memory Sticks.

The next screen display the Dell label-free design seen in many recent Dell monitors. Five buttons line the bottom right corner of the frame. Pressing either button brings up the OSD, which is parallel to the array of buttons, and each option corresponds to one of four buttons. Once a new menu appears, the function button changes dynamically, as the top two buttons become the up and down arrow buttons used to navigate through the menu of new view. Since any labels for the OSD buttons are actually on the screen (instead of on the bezel), calibration of the screen in a darkened room is easy.

The OSD buttons U2410 Dell has low sensitivity, which is sometimes necessary to push them harder than what we consider normal. The U2711 does not have this problem, as the appropriate response buttons.

Its OSD menu options include the level of brightness, contrast, and different color options. The presets are divided into two categories: Graphics and video. Graphics There are six presets to choose from: standard, multimedia, games, hot, cool, Adobe RGB, sRGB, and Custom. Your video presets are: Movie, Game and Wildlife. The presets do not change anything but the balance of red, green and blue, therefore, how well each institution is subjective. There are options to adjust the hue, sharpness and color saturation as well as additional options to configure the OSD to remain on screen until a minute (useful for anyone who will spend a good amount of time for calibration).

16:9 The Dell UltraSharp U2711 has an aspect ratio from 2,560 x1 ,440-pixel native resolution. 16:9 Monitor trend currently sweeping the market has many small monitors with higher resolutions than they were capable of 16:10 aspect ratio. A 22-inch model with a 16:9 aspect ratio now has a high potential definition, the native resolution of 1,920 x1, 080 (1080p) pixels instead of 1,680 x1, 050 pixels.
