One 1G memory module and two 512 memory modules

For now, two 512 is better than one 1G because it supports dual channels.

In the long run, 1 1G is better than two 512s, because buying another 1G can form a dual-channel with a larger capacity.

Now that the price of cabbage is in memory, what is there to consider, just buy it.

Truth be told, two are better than one but not much different.

It is recommended that you buy a 1G root to form a dual channel.

If you support dual channels, you can find the same 1G to match,When you match the computer, it may be for the sake of adding memory in the future1G,A single 1G and two 512M will not be very different。

Reasonable, in fact, there is no big difference between the use of dual channels and single channels (that is, you use a 1G or 2 512).As long as you have enough memory, it doesn't matter if you have a single order. If you want to change it, just add a 1G one.

As long as it is compatible with machine slots, you can plug as many as you want.

But if it is recommended, with a single 1g of the speed, it is faster than 2 and 512!

Theoretically, the effect of one strip is better than that of two combined, but it is estimated that the effect is no different.

No, you don't"Improvements"Finish.

The difference is not obvious, however, in the current era of memory cabbage prices, it is recommended that you use 2g....

Plausible. Not too.

Need. Now the memory is cheap, at least 2G.

With two systems, the speed of system operation and data access is 20%-30% faster than that of one, and there is not much difference in other things.

If the CPU is dual-core or two memory, it is recommended that you buy a memory of the same brand and model to add it, and now DDR2 memory is very cheap.

As long as both memory modules can be recognized by the motherboard and the frequencies can be compatible with each other, you can use the dual channel normally!

It's easy to determine whether two memories can be combined into dual channels, and you can see the motherboard parameters at a glance:

1. Look at the maximum memory that the motherboard can expand, divide this number by the number of memory slots, that is, the maximum capacity of the motherboard can identify a single memory, such as B85-G, the motherboard, which can expand up to 32GB of memory, has four slots, so it can support up to 8GB of single memory, and if you insert 16GB of memory, it will not be recognized.

Second, look at the maximum frequency of the motherboard to support the memory, if the motherboard only supports the maximum 1600MHz, you install the 2400MHz memory module will not be recognized.

3. The capacity of two memory modules can vary greatly, but the frequency must not be more than two levels. For example, 1600 is generally only backward compatible with 1333, and when the group is dual-channel, the bar of 1333 will be automatically downclocked to form a dual-channel with a frequency of 1067; However, if you put two pieces of 1067 and 1600 together, you will only be able to recognize one of them, and at worst you will have a blue screen.

It is better not to do it, if the model is different, it will cause problems with computer compatibility and cause hardware failure. If you want to use two, use two identical ones. Now the memory module is cheap, just buy a good one and use it.

Generally speaking, it's no problem.,But it's best to plug the big one into the memory slot closer to the CPU, you didn't say what brand model the other 2G is.,Add memory sticks,Try to choose the same as the original brand model.,If you can't do it, you can meet the model first.,If you can't meet the brand consistently.,Unless you want to form a dual-channel,Otherwise, the size problem is not serious.,The brand model size is all different memory mixing,It's really the next policy。

It depends on whether the motherboard can support it, and it can be used under normal circumstances.
