Memory stripe blending problem and solution method

Friends who often pay attention to three piece market changes will find that the current large capacity of memory is getting cheaper, which makes many users have the idea of upgrading memory. Looking at the current memory market, new to dig up the brand is really a lot, in the frequency of memory, now DDR266, DDR33 memory has slowly faded out of the market.

Friends who often pay attention to three piece market changes will find that the current large capacity of memory is getting cheaper, which makes many users have the idea of upgrading memory. Looking at the current memory market, the new brand is really many, in the frequency of memory, now DDR266, DDR33 memory has slowly fade out of the market, the mainstream DDR400 prices and the former has not too big gap.

Many old user machines are paired with DDR 266 memory, but because they can't buy the frequency of memory, most friends buy DDR 400 of memory, but because the frequency of these two types of memory mismatch, often encounter some trouble. In addition, many users in the purchase of memory strips after the memory of the machine is inconsistent with the model, which will cause a variety of problems, and then the use of different models, specifications of the various types of memory easy to summarize the following breakdown.

One, the computer does not boot normally

This is a common problem with different sizes of memory, and there are generally three ways to solve this situation:

1. Replace the memory strip. This is the most direct method. If you're buying a larger-capacity, high-frequency memory strip, you can first remove the original small capacity of memory, the newly purchased memory into the machine, if you can boot, the BIOS into the motherboard to the frequency of memory to the motherboard to support the frequency of memory to reduce frequency to use, so generally will not cause waste, And the stability is good, under normal circumstances also will not appear the problem. (Note that chipset support for memory frequency is different, such as the older 815 series chips can only support DDR266 memory, so if the purchase of DDR400 memory will be reduced to use.) ）

Another way is to plug the old memory into the front of the motherboard memory slot, where the two root cuttings slot can be plugged into the memory slot, so that the computer can be powered on occasionally.

2, the use of a single to enable the computer to boot, then enter the BIOS settings, the memory-related settings according to the low Speed memory specifications. For example: Use one of the memory (if it is DDR266 and DDR400 of the memory mix, preferably using DDR266 memory), the computer boot, into the BIOS settings, the operating frequency of memory and reaction time slow, with the old memory can be stable operation of the standard, When you shut down and insert a second memory, you can keep two of the memory working at the same frequency.

Second, the computer work is not stable, often crash

The problem of computer running instability is mainly caused by memory compatibility, and the basic idea of solving it is the same as above. The first is to replace the memory location, and second, in the BIOS to turn off the memory by the SPD automatic configuration option, changed to manual configuration. Third, if the motherboard with I/O voltage regulator, the voltage can be properly adjusted to enhance the stability of the memory.

Memory into the dual-channel era, the different models of memory plugged together to build a dual-channel more capacity to create a system instability phenomenon, this is because the products of different manufacturers in the design of different technologies, and dual-channel memory requirements are quite high, so if the two channels in the formation of frequent crashes and other unstable phenomena, You can test without building a dual-channel feature, which can be used if there are no problems.

The memory capacity is not correctly identified after mixing or upgrading memory strips

The causes of this phenomenon are generally as follows:

The first may be the cause of the motherboard chipset itself, and some older motherboards support only 256MB of memory capacity (such as the Intel® i815 series, which supports only 512MB of memory capacity), and the excess is not recognized and used. There are also cases where the motherboard cannot support high memory particles, and the only way to solve such problems is to replace the motherboard or memory. In some cases, you can also solve this problem by adjusting the insertion order of the memory, so you can try it yourself when you encounter this type of problem.

The problem of memory mixed-insert instability is an old problem. From the Edo of the year to the SDRAM to the DDR, this kind of problem persists. Therefore, although the high frequency of large-capacity memory, although the price and low frequency difference is not small, but we buy the first or from the motherboard and the old memory angle, attention to see the motherboard support memory capacity specifications, and pay attention to the memory of the brand and model, as far as possible with the old memory.

A wide range of memory on the market, its compatibility can also be different, big brand product compatibility is done quite well, so try to buy some big brand of memory, such as Kingston, Geil, their electrical compatibility is generally better, the probability of the problem is lower.

If you pay more attention to price, you can buy general memory, but to choose the wide PCB board memory, this memory is not like the narrow bar is in the PCB board, so from the stability and compatibility to say better, the price difference is very small.
