DDR667 memory insertion 2 dual channel or 3 single channel fast

First, AMD's CPU is an integrated memory controller, and it no longer needs to pass commands and data through the northbridge chip, which is beyond Intel's current CPU, so AMD's CPU does not have as high memory requirements as Intel.

Clause. Second, your 4000+ is 200*, the CPU external frequency is 200MHz, and the actual operating frequency of the memory is only 400MHz. If you exceed the CPU external clock to 333MHz, the 667 memory will run at full frequency.

Third, AMD's CPU does not have dual-channel requirements for memory, or there is not much performance improvement on dual-channel. Dual-channel is only effective for Intel's CPU, but the performance improvement is also far less pronounced than it is stated, generally believed to be around 15-20%.

For the AMD platform, due to the integrated memory controller inside the processor, it is not very sensitive to dual channels, and whether it is assembled or not, it will not bring a great performance improvement, and generally speaking, it may increase the performance by about 5%. Intel is different, the Intel platform is still relatively dependent on dual channels, and generally speaking, it can bring about 20% performance improvement. Finally, it's important to point out that no matter what platform you have, if you use integrated graphics, you should try to consider dual-channel!

In the case of a small memory occupancy, it is better to form a dual channel.

If 2GB of RAM is not enough, use 2T mode.

Generally, the dual-channel built with 2G of memory is enough for you, even if you open World of Warcraft, it should be no problem.

First of all, the dual-channel performance improvement is not very large, and the improvement of a U is even less significant.

There is a bit of a difference between 1T and 2T, but 2 1T is not as good as 3 2T at the same frequency, and large memory is better than low timing

The reason why it can't reach 333 is that a u integrates a memory controller to reach the standard frequency, and it is good to exceed the point frequency of u

How are memory parameters set?

To put it simply, it is to increase the frequency as much as possible and reduce the timing under the premise of stability! The extent to which low parameters and high frequencies can be reached depends on your hardware system.

Try to find the limit yourself.

It must be three fast, and the performance improvement of dual channels is 10%-15%. You plug in three, and the performance increase is 50%.

The memory working frequency is generally 300MHz, which is not up to the standard frequency of 333MHz of DDR2 667.

The frequency of DDR2 667 is 667, halo.

The memory is sure to be easy to use! Nothing.

You can't feel it because 1GB of RAM is enough.

It can form a double channel.

However, the motherboard BIOS will automatically balance the frequency, so that the high-frequency memory to the low frequency to ensure the stability of use.

The same generation of memory, when the frequency is inconsistent, it can be mixed, but it is important to know that the high-frequency memory will automatically reduce to the low frequency, and the low-frequency memory forms a dual channel, and the memory of different generations cannot be mixed. DDR4 2666 MHz memory, if you want to add DDR4 2400 MHz memory, the motherboard will let the 2666 MHz memory module drop to 2400 MHz, and then form a 2400 MHz dual channel.

Different capacities, different brands, and different frequencies can be compatible, however, if you add a DDR2 2666 MHz memory, it will not work normally, because one is DDR2 and the other is DDR4 is not compatible.

The operating frequency of dual-channel memory is limited by motherboard support in the first place, if the motherboard can only run at 2400 MHz, then 2666 MHz memory can only run at 2400.

There are as many slots as there are plugged in, and capacity is more important than frequency. So just plug it all in. The frequency will be reduced to 2400

,,Whether it is possible to form dual channels, the compatibility of the two brands of memory is a key issue. The results are only known when two types of memory are tested on the machine.

Summary. Hello, in terms of performance, there is a big difference between DDR5 and DDR4. DDR5 is an improved version of DDR4 that has higher bandwidth and lower latency, and supports more memory capacity.

As a result, DDR5 has better performance and can provide faster data transfer speeds to better support complex applications and games. In addition, since DDR5 supports higher bandwidth, more memory capacity can be used, allowing for better support for multitasking. If only the memory capacity is considered, the DDR4, 3200MHz, 16G group dual-channel memory capacity is larger, which is more suitable for applications that require a lot of memory.

Therefore, in terms of performance and memory capacity, DDR5 6000MHz 8G group dual-channel memory and DDR4 3200MHz 16G group dual-channel memory have their own advantages and disadvantages, which need to be determined according to the usage scenario.

Please consult DDR5,6000MHz,8G group dual channel a total of 16 memory,DDR4,3200MHz,16G group dual channel,These two dates are better than punching oranges, which is better for loose rock groups?

Please consult DDR5,6000MHz,8G group dual channel a total of 16 memory,DDR4,3200MHz,16G group dual channel,a total of 32G memory,These two daily Sen Sui shooting processing work applications and game entertainment comparison,Which is better?

Okay, thank you.

In the parameters of the motherboard, it is stated that dual-channel DDR2 1066 800 667 memory is supported, which means that the motherboard supports dual-channel memory, the type of memory is DDR2, and the frequency of the memory supports three types.

Dual-channel is the design of two memory controllers at the Northbridge (also known as MCH) chip level, which can work independently of each other, and each controller controls a memory channel.

In these two memories, data can be addressed and read separately by the CPU, doubling the bandwidth of the memory and doubling the speed of data access (theoretically). The popular dual-channel memory architecture is built with two 64-bit DDR memory controllers with a bandwidth of up to 128 bits. Because the two memory controllers in the dual-channel system are independent and complementary intelligent memory controllers, they can operate simultaneously with zero waiting time between them.

This complementary "nature" of the two memory controllers allows for a 50% reduction in effective wait time, doubling the bandwidth of memory. Dual-channel is a new technology used in a motherboard chipset (Athlon's 64 is integrated into the CPU) and has nothing to do with the memory itself. Any DDR memory can work on motherboards that support dual-channel technology.

Just note that out of more than three memory slots, the group of dual-channel memory should be plugged into two memory slots of the same color.

8+4 capacity can also be a dual-channel group.,I tried it myself to know.,Anyway, the computer won't explode!

Put two 4G into a dual channel. 8g spare.

If you want 8G to be dual-channel, it must be two 8G, and the motherboard has two main and two auxiliary 4 memory slots, so that the two main slots can achieve dual channels, it must be the same brand, the same frequency, and the same capacity. If it is different, it will be backward compatible, 8G and 4G are plugged into the main slot, and half of 8G and 4G are dual-channel. The excess only increases the memory capacity.

The same color forms a double channel.

From this, it will be understood that two 4Gs cannot be considered as one 8G.

Can't 2 4G can be dual-channel.

Personally, I think a single channel 768m is good, after all, the capacity is larger, but isn't it elastic dual channel?

Plug it in at the same time. Don't mind too much about dual channels, in your case, the first thing to consider should be the size of the capacity. The bigger the capacity, the better.

Because you use SD memory, now you can rarely find a new one, memory divided into SD, DDR333, DDR533, DDR667, DDR800Now 667's are easy to buy,**It's not expensive,I suggest you upgrade the machine,Change the motherboard,Add a larger memory,Samsung and Kingston are good,Compatibility is good,But the CPU may also have to be changed。

Where does the 32bit saying come from? The memory bit width is 64 bits, and the dual-channel is 128 bits

DDR2-667 dual-channel memory theoretical bandwidth=

DDR3-1066 dual-channel memory theoretical bandwidth=

Whether the equivalent frequency or the clock frequency is really the same thing, it's just a matter of which multiples need to be multiplied.

Let's talk about it in more detail:

The formula for calculating memory bandwidth is as follows: bandwidth = memory core frequency, number of bits on the memory bus, and multiplication factor.

Let me start with the technology of DDR, DDR uses the rising and falling edges of the clock pulse to transmit data once, and one clock signal can transmit twice the data of SDRAM, so it is also called double-rate SDRAM. Its multiplier factor is 2.

DDR2 still uses the technology of transmitting data once for each of the rising and falling branches of the clock pulse (instead of transmitting twice), but the pre-read 4-bit data at a time is twice that of the DDR pre-read 2-bit at a time, so its multiplication coefficient is 2x2=4.

DDR3 is an upgraded version of DDR2, and the most important change is that it reads 8 bits at a time, which is 2 times that of DDR2 and 4 times that of DDR, so its multiplication coefficient is 2x2x2=8.

It should be added that there are three different frequency metrics for memory, which are core frequency, clock frequency, and effective data transfer frequency. The core frequency is the working frequency of the memory cell array, which is the actual running frequency of the memory. The clock frequency is the transmission frequency of the i o buffer (input and output buffer); The effective data transmission frequency refers to the frequency of data transmission. DDR3 memory prefetches 8 bits of data from the memory cell at a time and transmits it simultaneously in the Iobuffer (input-output cache) rise and fall, so the effective data transfer frequency is up to 8 times the core frequency of the memory cell.

At the same time, the clock frequency of DDR3 memory is increased to 4 times that of the core of the memory cell. In other words, the core frequency of the DDR3-1066 memory is only 133MHz, its IO frequency is 533MHz, and the effective data transmission frequency is 1066MHz.

Since the SDRAM-DDR era, the data bus bit width clock has not changed, and it is 64 bits, but with dual-channel technology, it is possible to obtain a bit width of 64x2 = 128 bits.

1066 refers to the effective data transmission frequency, divided by 8 is the core frequency. It adopts a single-channel mode with a bit width of 64 bits. So.

Memory bandwidth = (1066 8) 64 8 = 68224 Mbit.

It can be seen that if the memory works at the nominal frequency, the nominal frequency bit width can be directly used to simplify the formula.

According to 8bit (bit) = 1byte (byte), 68224 8 = 8528mbyte = is obtained.

Two DDR3 memories with a nominal value of 1066, the bandwidth = after forming a dual channel

DDR2 667 has a maximum speed of 667MB s, and dual-channel DDR2 667 has a maximum speed of 1334MB S;

DDR3 1066 has a maximum speed of 1066MB s, then dual-channel DDR3 1066 has a maximum speed of 2132MB S.

MB s is read as megabytes per second, and MB s is read as megabytes per second.

Dual-channel DDR2 667M (32bit) Isn't it calculated?

And dual-channel DDR3 1066M (32bit) obtained?

A: Not at all. 667 refers to the bus frequency, and the memory size is the specified size, for example, 1G is 1G, and no calculation is required.

Another important question is whether the memory bandwidth must be calculated at the equivalent frequency? (How do I seem to have seen someone calculate with clock frequency?)

A: The memory bandwidth is not calculated at all.
