It turned out to be 667 memory, and it was replaced with 800 memory There is a problem

The memory frequency options in the BIOS are only 667 533 400 and AutoThe motherboard supports 800's. Also upgraded the BIOS...

- I haven't seen this situation before, I have seen a memory frequency protection in the BIOS settings of the brand motherboard, and you need to turn it off before you can identify other frequency memory.

Can the landlord report your motherboard and CPU model?

In addition, you said that the motherboard supports 800 with CPU-Z, which is a bit strange, and there is an SPD in CPU-Z that should be the SPD parameter for memory solidification. It doesn't say whether the motherboard supports 800.

Because your computer motherboard is supported to DDR2667

Normal - 800 and 667 together, 800 will be downclocked to 667 to synchronize...

I don't see when or where lz expressed that only one memory was inserted. There is also please lz self-respect, ask for people to ask for the like, if you have any questions, just say, come to study together, don't be as domineering as a master, don't be welcome!

Brush the biosThe old motherboards are like this! Both show 667

I don't know and don't tell you, you're too stringed.

Then it should be that your memory may be polished goods, problematic. And are you using a mixture of the two? Mixed up, it's 667

It is normal for two to be used at the same time, and the frequency is pressed on the lower one.

If you use 800 alone, you still use 667, which means that the memory frequency is not adjusted in the BIOS, and the motherboard is discharged and forcibly re-self-tested.

By default, it is automatically recognized in the BIOS.

You don't still take off the motherboard battery, wait 3 minutes to put it on, and it will automatically become auto.

Memory groups with different frequencies are dual-channel, and the smaller frequency is taken.

Hello. If you just change the original 667 strip to 800, there is no difference in the BIOS without any settings.

The memory frequency is related to the external frequency of the CPU, if your external frequency is 266, set the external frequency memory ratio to 2:3 to make the 800 strip really work on the frequency. The same goes for other external frequencies.

Whether the purchase of 800 strips can bring significant improvement also depends on the performance of your other hardware. If the bottleneck of the whole machine is on the CPU or graphics card, it is obviously unwise to change the memory.

As for the difference in memory frequency, 3ds Max is not noticeable when modeling, and the acceleration effect on rendering is not obvious. The factors that affect the rendering speed are the CPU speed and the memory size. In most DX9 3D games, the difference is also relatively small.

A simple analogy is this: if I secretly turn on your computer in the middle of the night and change the memory to 800, it may take a long time for you to notice it from the POST.

Most of the 667 memory with a good physique can exceed 800, you can experience the effect after 800, and then decide whether to buy 800 slivers.

The frequency is different, and of course it feels different when it runs!

The frequency of DDR memory and DDR2 memory can be expressed in two ways: the operating frequency is the actual working frequency of the memory particles, but since the DDR memory can transmit data on both the rising and falling edges of the pulse, the equivalent frequency of transmitted data is twice the operating frequency; DDR2 memory, on the other hand, is capable of reading and writing data at four times the operating frequency per clock, so the equivalent frequency of transmitting data is four times the operating frequency. For example, the working frequency of DDR 200 266 333 400 is 100 133 166 200MHz, and the equivalent frequency is 200 266 333 400MHz; DDR2 400 533 667 800 operates at 100 133 166 200MHz and 400 533 667 800MHz equivalent

Of course there is, for example, my X2 4200+ CPU runs at 667 at 200 external frequencies, and 800 at 219 external frequencies

Of course. Performance is like the difference between QQ and BMW.

Actually, there is no difference? If you don't have Bois settings you won't be able to see their performance, and for the average user, you won't have to think about it at all.
