In the first Phenom processor screenshots many readers noticed that utilities like CPU-Z say that there is only one channel memory. It became clear later, that AMD formally used two 64-bit memory controller in Phenom.
It turns out that these particular memory device controller in Phenom processor caused some concern among memory producers . Many motherboards reported at the initial loading time the existence of only one memory channel , and many user in this case can complain about a defective memory!
In XtremeSystems.org the official representative of OCZ Technology company made the necessary explanations. Phenom Processors have two modes of working memory controller:
- ganged mode -> 1 x 128-bit wide, dual-mode;
- unganged mode -> 2 x 64-bit, dual-mode.
The latest version is preferable in multithreaded applications , but it is misleading for diagnostic tools and initial motherboard load .
