hi
the unganged mode is called to improve the performance of multi-threaded software and it's better for oc
so
i want to know what is the dc symmetric mode ?
and what is the nb frequency ? and y it's not active in the second pic ?

Ganged and Unganged is a AMD thing. Both are Dual Channel. But Ganged is the memory controller running as a single 128bit controller and Unganged is running as two 64bit controllers.

Symmetric is a Intel thing. If you have a 1gb stick in one channel and a 512mb. in the other it is Symmetric mode. If you have a 1gb. stick in one channel and two 512mb. in the other channel its Dual symmetric mode. Either is better then single channel mode.

Well in the top CPUz is kinda misleading. On a AMD the Northbridge chipset really runs at 200mhz. But the HyperTransport runs at 2000mhz. So what its calling the NB Frequency is really the HyperTransport speed.
 
Symmetric is a Intel thing. If you have a 1gb stick in one channel and a 512mb. in the other it is Symmetric mode. If you have a 1gb. stick in one channel and two 512mb. in the other channel its Dual symmetric mode.

It is?

AFAIK symmetric dual-channel is the "proper" dual channel, i.e. pairs of sticks with the same capacity. Asymmetric is pairs of different sticks, where some accesses happen in dual-channel mode and some in single-channel mode, depending on the exact memory location.

If you have a matching pair its just Dual channel

If you have say a 1gb. stick in one channel and two 512mb. sticks in the other (the amount is equal in both channels) its called symmetric dual-channel .

But true if you have different amounts in each channell technically its called Asymmetric mode.

Usually "proper" dual channel is called Interleaved. In the case stranglehold mentioned, 1GB + 2x512MB, I believe an Intel controller will still be able to interleave that. It's possible CPUz is calling that symmetric mode though.
