【 Weak current College 】 memory plug common problems and solutions

Panoramic view of the current memory market, brand new digging really many, in memory of frequency, now DDR266, DDR33 memory has slowly fading out of the market, mainstream DDR400 price and the former has not gap, but DDR2-667 memory has become the main force in recent market.

Although DDR2 memory has become mainstream, but DDR memory still upgrade the user's preferred, especially the Vista operating system on the memory capacity requirements increase, the giant many early 939, 754-pin of the user only through upgrading memory to smooth running VISTA system.

Many of the old user's machine, and match is DDR266 memory, but has been unable to buy into this frequency of memory chips, so most of my friends bought DDR400 memory, but since these two do not match the memory frequency, tend to have some trouble. In addition, many users buy memory stick after discovery and machine mounted memory model is not consistent, which also cause various problems, the next step towards the use of different models and sizes of memory fault-prone of all kinds are summarized below.

First, the computer does not boot

This is to use different sizes of memory stick a widespread problem, this is the case generally have three solutions:

Article 1, replace the memory. This is the most direct way. If you are purchasing a larger-capacity high-frequency memory stick, you can first be original smaller memory is removed, the new purchase into the machine, if you are able to post, then go to the motherboard's BIOS will memory frequency down to motherboard supported memory frequency value to block the use of, this is generally not wasted, but stability is better, generally do not cause problems. (Note the chipset to support different memory frequency, such as older 815 series chip can support DDR266 memory, so if you buy DDR400 memory have fallen over. ）

Alternatively you can set the old memory tiaocha to motherboard memory slot a top position, i.e. twoslot to plug in the memory slot and a location so you can use the computer power on every once in a while.

2. the use of a separate will power on the computer, then enter the BIOS Setup, and memory-related settings in accordance with the specifications of the low speed and memory. For example: use of a memory (DDR266 and DDR400 memory mixed use, it is best to use DDR266 memory), start your computer, enter BIOS settings and memory frequency and response time slow to run old memory can stability prevail, shutdown after inserting a second root memory to make two memory remains the same frequency.

2. computer precariousness, often panic

Computer running unstable such problem appeared mainly memory compatibility, solve the basic idea is the same as above. The first is to replace the memory location; second, turn off the memory in the BIOS by SPD automatic configuration option changed to manual configuration. Third, if the motherboard with I/O voltage regulator, voltage can be increased as appropriate, strengthen memory stability.

Dual-channel memory access times, different models of memory together form a dual channel more capacity result in system instability phenomenon, this is because different manufacturers ' products are designed not to make use of technology, and the dual-channel memory requirements quite high, so if you are in the form of dual channel deadlock occurs frequently, such as instability, you can not set up for dual-channel functionality to test, if not you can in this way.

3. plug or upgrade memory stick, memory capacity, identify improperly

This might be caused by generally have the following:

The first may be the cause of the motherboard chipset itself, some old motherboards only supports 256 MB capacity (e.g. intel i815 series highest only supports 512 MB of memory capacity), the excess part does not recognize and use. Of course there is the result of Board cannot support high memory particles, the solution to the problem, the only way is to replace the motherboard or memory. In addition, in some cases by adjusting the memory of the insertion order or you can resolve this issue, we encountered this kind of problem you can try it yourself more.

Memory plug instability problems is an old problem. From the EDO to SDRAM and DDR, such problems persist. Therefore, although the high frequency of large-capacity memory while prices and low frequency difference is not great, but we buying initially or from the motherboard and the angle of the old memory, see the motherboard supports memory capacity specifications, and the memory of the brand and model, the old memory possible.

Markets a wide variety of memory, its compatibility also different, big brand product compatibility will do quite well, so try to buy some brands of memory, such as Kingston, jinbang, their electrical compatibility in General is better, there is a problem with the chance to be lower.

If the comparison focuses on price, you can purchase general memory, but try to choose wide PCB's memory, the memory of exclusion is not like the narrow strip that is within the PCB from the stability and compatibility is better, the price difference is very small.
