Depressed about the problem that the memory 400 and the motherboard only support 333

There is no need to change the motherboard. Changing to a 400 motherboard has very limited performance gains.

333 memory is DDR333, and 400 is DDR400. It is said that the frequency at which the memory is working. The higher the operating frequency, the larger the data transfer bandwidth of the memory.

The memory data bandwidth of DDR333 is 166*2*8=2656MB SDDR400 is 200*2*8=3200MB The problem of more people jumping is not entirely because of memory, and it has something to do with your entire system, especially the graphics card. If your graphics card isn't very bad, there shouldn't be a problem with jumping.

It's not necessary at all, because the frequency of the memory depends on the external frequency of your chip, which is FBS. The data given on the first floor is based on any factors and only the memory frequency.

However, if you consider FBS, then your chip has an external frequency of 166 instead of 200, which means that you get a motherboard and memory that supports 400 memory, and you can only use it as a 333.

The specific data calculation is very complicated. I won't go into too much detail here.

Not like that.

Your DDR400 is certainly better, but it is not the world.

DDR400 can be adjusted down at 333, and the performance is not bad to **.

You can't see the gap when you play CS.

And I don't know if you're dual-channel, dual-channel, it's best not to mix memory with different latency.

400 can only be used as 333, nothing else,

The memory will be backward compatible,But according to what you said, your motherboard should support 400 memory,It's only in the BIOS that the frequency is turned on and the CPU synchronization will be automatically reduced.,It's definitely worth talking about memory.,But on the whole,It's not worth upgrading to the old machine.,After all, the current machine is low.,The performance is better than your machine.。

It is recommended that you dispose of this machine and add some money to a new one.

There is not much difference between working in the state of 400 and working in the state of 333!! Only the DDR400 is available now! So if you want to upgrade, don't worry too much.

400 memory is something that has been eliminated The price is not cheap It's a waste to buy that You can only buy second-hand ones and it's easy to be fooled Buy a lot of fake electronic waste in Guangdong Even if you buy it and can use it It won't be sold in the future Now it's all DDR2 DDR3 memory DDR motherboards can't be found.

Yes, no problem, it will automatically downgrade to 333 when plugged in

Yes, the above answers are correct, it will be reduced to 333, and the display is also 333 when self-checking, in addition, you must pay attention to compatibility problems, and run some test software to test the stability of memory when you buy it

Yes, but it will automatically drop to 333

There will be no effect, and the 400 will drop itself to the working frequency of 333.

It should work together and the memory is backward compatible.

Plug it in together and use it, don't worry about the rest.

As long as the brand is the same, it is generally fine, and it should be compatible.

You plug both of them in and use them together!

Addendum: The 133MHz you detected, I'm afraid it's just what the software shows. 133MHz x2,=266MHz,Dual-channel data is DDR266,I'm afraid the software doesn't display or you don't pay attention?

Since your board only has two memory slots, it's definitely DDR for 845G. If there are SDR slots at the same time, there will be 4 slots.

You can use DDR333 or 400.

Landlord, you first confirm whether the board is 845 or 845gDifferent things, don't look at it, they all belong to the 845 series.

In addition, if the board is 845g, then the three of you upstairs are either rookies, or you are not spoofing, hehe.

i845, which is equipped with William Core Ben 4, supports SDR memory, and cannot use DDR memory!

The new i845, that is, 845E, 845G and 845GL, uses DDR memory, not SDR memory!

Among them, 845G supports DDR333. If you plug in the DDR400, it will be automatically lowered to 333If mixed with DDR333, it also works as 333!

The landlord said that you can use 133 memory, then unless your board is with two memory slots, two are SDR, two are DDR, you pay attention to their different fractures, there are two fractures on the slot is SDR memory, and only one fracture is DDR. This can be done with DDR333 or 400

It seems that such an early motherboard does not support the use of downclocking.

The 133 is an early DRAM memory, and it is not the same as the DDR1. The mouths are not the same size, and they can't be inserted at all.

If your motherboard has two RAM slots (SDRAM, DDR), you can insert 333 or 400 RAM.

You can't use the wrong interface, and the current mainstream memory is a DDR2 interface.

Your motherboard is not connected to the SD interface.

Currently, motherboards like the high-end X38 790FX support up to 8G

Up to DDR400 memory will be downclocked to 333.

The current DDR2 memory is not available.
