Can DDR667 be used for downclocking?

Your motherboard doesn't support DDR2, DDR400 is OK.

Forget it, if you can use new hardware for the old machine, do you want to buy a new one?

You plug in DDR2 533 and you can downgrade.

Not supported, only DDR400 can be used

The DDR667 you are talking about should be DDR2 667

The interface between DDR and DDR2 is different.

Dual-channel conditions: The external frequency is the same, and the capacity is the same, so even if your motherboard supports dual-channel, it is impossible to form a dual-channel.

There is no need to scatter the motherboard itself to reduce the frequency of the optimization, and the master shows that the working frequency of the two memories is inconsistent, and the memory is backward compatible.

The motherboard does not support dual channels.

Not necessarily!

The main thing is to look at the performance of the board!

Mine is the one that doesn't have a downclock!

Now it's a 400's!

If you look at CPUZ, you can see if there is a frequency reduction.

The 667 and 800 strips do not form a dual channel, but the 800 will definitely be downgraded to 667. The condition for opening the dual channel is that it must be the same frequency, the same capacity and not necessarily the same brand.

DDR800 will automatically drop to 667.

Dual-channel memory should also be the same frequency.

Incompatibilities of the same brand are rare

However, the different frequencies will definitely drop

That's right, CPU Outer Frequency x4 = 800

Don't forget the motherboard front-side bus.

Whether the motherboard is set to RAM 667 frequency.

It has to do with the external frequency of your CPU. Your CPU external frequency may be 133. If the motherboard supports asynchronous memory technology, you can refer to the manual to modify it. It can work in 667 mode.

What is your CPU, if the CPU front-side bus is 533, it can only work at 533.

No need to set up, automatic frequency reduction.

It's the transmission frequency of the memory channel.,The higher the y, the better.,It's like a little too much to call me a hero!
