Some people say that two 512M 667 memory and a motherboard that supports 533 can make 1066

Plugged into that kind of motherboard, the frequency drops to 533M, and the bandwidth is doubled if it is dual-channel, but it can't be said that the frequency is 1066M, and the bandwidth is the same as 1066M, but the performance can't be compared.

Also, the working frequency frequency of DDR533 is 266, but the working frequency and the actual frequency are not the same concept, DDR (Double Data Rate 2) itself can work at twice the frequency of itself, and the actual frequency is 266*2 533, so the dual channel upstairs is DDR533 is not right.

When pigs fly. This is pure nonsense.

The 667 is used on motherboards that only support up to 533, and the motherboard will downclock the 667 to use 533.

Note that DDR2 533 is not 1066 after dual channel, and it can really be called DDR2 533 after dual channel

It should be that its real operating frequency is 266, and the transmission speed after the cool channel is increased by 1 time.

Equivalent to the 533 frequency memory transfer speed, so people call it DDR2 533 instead of DDR2 533 after dual channel equivalent to 1066

No, he may be talking about dual-channel memory, the frequency remains the same, the bandwidth is increased, and the performance is only about 10% improved.

It's better not to do this, the compatibility is not good.

As long as the motherboard supports dual channels, it's fine, but the two memories can only run at a frequency of 533, which is a bit wasteful.

I guess you can't buy 533 memory, right, it doesn't matter if you buy 667.

It is also estimated that you are on the Inter platform, so dual channels can improve the performance of your whole machine by 20%, and AMD's can only improve by 5%. And if you're using a graphics card, the dual-channel sedan can also greatly improve the performance of the integrated graphics card.

Whether you can form a dual-channel depends on your motherboard, and dual-channel is said to have a performance improvement of about 5%-10%.

Generally speaking, there is basically no essential difference between the memory and 2G, and this is still in the case of the same specifications.

First of all, your 3 is definitely not dual-channel, then the transmission rate under a single channel can be maintained at 667, plus a 533 to force the entire running rate to drop to 533, and in exchange for 512M space is obviously not cost-effective, unless this strip and your original strip with the same specifications to form a dual channel, it is still more feasible, if it is incompatible, 4 running together may also lead to inexplicable problems, such as blue screen, can't turn on, etc., so it is still not recommended that you buy this.

This frequency is not felt by the player. There is only the point of running scores.

To be honest, the XP system is no different from 2G.

Depending on what you're doing, it generally doesn't have much impact.

No. It can't be plugged in at all, and the interfaces are all different. Try it if you don't believe it.

The memory of the 1066 comes in two specifications:

One is DDR2, as long as it is this, your motherboard will definitely support it and can be used on your motherboard. But it will automatically drop to your motherboard's 533 frequency usage.

The other is DDR3, which your motherboard does not support and is not in the same position as DDR2, so it can't be plugged into your motherboard, and your motherboard can't be used.

DDR2 1066's memory can't be found, DDR3 1066 is a lot, but 3 is not supported.

There are highlights on the 2nd floor. . . Not bad! Promising.

533 definitely does not support 1066, and the memory cannot be inserted.

If the motherboard does not support it, it will be used at a reduced frequency. However, it is a bit useful to replace your memory module with 1G to 2G.

Landlord. Don't even think like that... 1066 is DDR3, 533 is DDR2, and it would be good to support up to 667 or 800.

Of course you can, it's a big deal to use the frequency reduction (a bit wasteful).

Yes, as long as it supports DDR2, but the previous 533 and a 667, his DDR can only run to 533, and the lower is not the higher.

The high ones will be adjusted to the low ones.

I'm afraid that your memory is not compatible with each other.

It is said that it is taken off and not taken up, that is, 533 667 together 667 becomes 533

No, if your 533's memory is of excellent quality, you can overclock the 533 to 667, so isn't it the same frequency?

Don't worry about the side low.

Looks like it has to be the same brand, right?

Of course, it is impossible to support it, DDR2 is supported from 915 (some vendors and some types support), and the full support is 945.

Definitely not work, the interface is not right, and it can't be plugged in.

Memory can,Why add 512MB It's too small It's too small to add a DDR2 2G,Otherwise, it's pointless to upgrade,Specifically, because I don't know what model your CPU is, look at the motherboard should be an Internet brand machine, that is, if the motherboard is a supported integrated graphics card, then there will be no slot for the independent display,Because this is a common problem of brand machines,If you add a separate display,Then the upgrade does not support too high graphics cards,The reason is the bottleneck of the CPU Speeding up 8500GT or 8600GT is the most suitable, basic mainstream games can be played, adding too good graphics cards is basically useless, and the functions of the graphics card can't be played at all, which is too wasteful. If the CPU belongs to the above, then you can choose HD4670 or HD4850 4870, that is, the power consumption is large, and the external power supply must be connected, which is also a common problem of the brand machine, and the power supply can also be suitable for the supply of the original machine, that is, you must change the power supply, the power consumption is larger, and it is best to have more than 320W. If you want to insert a 9500, 9800gt graphics card, then you must also change the power supply, 320W or simply change to 500W.

Not enough memory. Change the memory again. It also depends on the CPU to change the graphics card, and the CPU can't be moved. Even adding a graphics card is useless. Motherboard with 9800GT can be a bit of a struggle. 9500 should work.

No problem with the memory, 9500gt is recommended for the graphics card.

The power supply for brand machines is generally just right, and the maximum power of your machine is less than 250W, which is generally 220W. Therefore, it is recommended to upgrade the power supply as well.

The rated power of 9500GT is more than 250W, and 9800GT is more than 350W, do not use miscellaneous brands!! Remember

Yes, you can add food to the memory.

If you have a graphics card, you can try it if you have a socket.

Don't you think plugging in the 9800GT is a bit of a donkey pulling a big grind?

Now DDRII 667 on the market is the mainstream memory frequency, cost-effective, you can directly buy a 512M or 1G capacity, with the original memory, the system will automatically reduce the frequency to use, no need to manually adjust.

Now DDRII667 512M is 95 yuan, 1G is 160 yuan, or 1G is more cost-effective.

However, I think it seems that the 649 chip supports DDR memory instead of DDRII.
