Treatment of common faults of memory skills

1: fault diagnosis and treatment of
memory installed improperly or had serious quality problems often lead to power "memory alarm", is one of the most common faults in memory. At boot time, hear not the usual "tick" sound "tick, tick, tick..." ringing, no image displayed on the monitor.
This is most of the time because the computer environment is not good, too much humidity, in use for a long time, gold finger surface oxidation of memory, causing memory gold finger contact resistance increases with the memory slot, hamper current self test error caused by memory.
such memory failures more obvious, easily reinstall or replace the additional memory to be identified and resolved. After removing the memory section, note be careful using ethanol and rubber on both sides of the memory-metal fingers clean, and do not use the hands touch the finger, because sweat will be attached to Jin on the fingers on the hand, causing Goldfinger in use for some time again oxidized, repeated the same failure, installation can be changed a few memory slots.
in addition, we also apply the brush to brush the dust cleared in the memory stick slot, and then with a hard and clean white paper folded, moving back and forth in the inserted memory stick slot, which makes paper wipe clean the memory slot in the metal, and then install the memory. Simultaneously to look for chip burned, damaged the circuit board traces. In addition some old memory (EDO RAM), the installation must be used in pairs. Rambus RAM memory slots on the system board must be populated to function properly, if there is no plug, similar to Rambus shape you need to use a special "threaded" plugged into a free slot.
memory poor quality or damage to system instability as a result of fault, is computer repair process, most of the problems encountered. Like frequent the "blue screen of death" and "registry is corrupted" error or Windows often automatically go into safe mode.
such as encounter "registry error", we can go into safe mode, in run Type "MSCONFIG" command to "start" ScanRegistry in front of the "v" to remove, and then restart the computer.
If the troubleshooting indicates that the problem is really caused by registry errors if the fault persists, it can be concluded that the machine basically problem when using the Replace method, changing good performance on memory tests if the same fault. Sometimes, not disk defragmentation for a long time, when there is no error checking, and also cause system errors registry errors and prompted, but for this kind of problem in relation to running "ScanRegistry", the system can work, but at a significantly slower.
resolve this type of problem except to replace the memory stick, you can also try adjusting memory parameters in the motherboard BIOS. If memory does not meet the targets set in the BIOS requirements, will make the memory work in non-steady state conditions, suggested itemized lower CAS and RAS in the BIOS settings for parameters such as numeric values. If your memory is not brand-name products, it is best to select default settings for "SPD", or "auto-detection mode". In SPD mode, the system automatically gets information from the SPD chip memory, so in theory, this memory work is the most stable.
most memory synchronization modes, memory speed and the CPU FSB is the same. But now many of the motherboards support "asynchronous memory speed" that operates there are some differences between the two. A case study of typical VIA KT333 motherboard, after entering the BIOS found "DRAM Clock (clock frequency-memory)" option, which is "the Host Clock (bus frequency and memory frequency synchronization), Hclk-33M (bus frequency reduction of 33M), Hclk+33M (bus frequency and 33M), three models. If the memory is not stable, memory speeds can be set lower.
2: fault in the
is the easiest to upgrade one of the parts in the computer memory. Since we use is produced by different manufacturers products grouped together, no compatibility issues of most concern. Because the upgrade properly, can lead to system instability, memory is not fully identified, could not even boot and a series of failures.
during the upgrade process, the mixed insertion of the memory problems often occur, one of which is for single and double sided memory caused by the mixed insertion. Double side often need to take two "BANK", while some older motherboards may present compatibility issues (like INTEL's older boards such as LX/BX/810/815), you can only recognize half of the capacity. Single and double side also would 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 package is supported by motherboard chipset is better. It is undeniable, the same amount of memory, one side is higher than double integration, production date be later, so it's more stable.
we are very interested in whether two different specifications of memory stick can be used on the same Board, in fact, different manufacturers and different models, different speed memory can be used, but have certain effects on the stability of the system, in particular, will have an impact to the overclocking performance. Users use when two or more memory modules, should choose the same brand and model of the product, so you can minimize memory phenomena that are not compatible. If you cannot buy the same as the original memory stick products, should be used in good reputation brand memory stick on the market, they are subject to stringent special matching and compatibility testing, components, design and quality can meet or exceed industry standards. Of course, not all brands of memory chips have good compatibility.
again, be aware of when using memory-related parameters can be set in your motherboard BIOS was conservative, such as DDR266 memory case mix and DDR400 memory, you can set the parameters according to the requirements of DDR266 memory, while SPD feature should be disabled, so as not to cause confusion.
in addition, we often speak of "dual-channel memory" is actually a motherboard chipset technology, has little relationship with the memory itself. There are nVIDIA nForce2 and Intel i865/i875 chipset supports dual channel memory technology. On the i865/i875 Board to implement dual channel memory technology, must use the same specification and capacity two or four memory. Only strictly according to the DIMM1+2 (Board only two memory slots), DIMM1+3, DIMM2+4 and DIMM1+2+3+4 the four memory installed in order to build the dual-channel mode. Formed in nForce2 motherboard dual channel memory mode, the memory capacity and models there is no strict requirement, with two or three memory can be, just make sure you plug your memory in DIMM1, DIMM2, DIMM3 anywhere to plug in one or both of the memory, can turn on dual channel. Very easy to use. In dual-channel mode is established, we can see the BIOS information at boot time identification of the dual-channel memory.
