dual channel con 6 gb?

[cldo]

ciao!
se io metto: 2 banchi da 2gb l uno +
2 banchi da 1gb l uno(tutti e 4 stessa marca e stesso codice a parte le dimensione variabile di 2 gbe 1 gb),gireranno in dual channel?
ho una asus p5k.
grazie!

si i primi 4 giga mappati (non i moduli fisici) andranno in dual-channel i rimanenti 2 giga mappati (non i moduli fisici) andranno in single-channel.

You may install varying memory size in Channel A and Channel B. The system maps the total size of the lower-sized channel for the dual-channel configuration. Any excess memory from the higher-sized channel is then mapped for single-channel operation.

NON SPECIFICA CMQ SE SI TRATTI DI DUAL-CHANNEL SIMMETRICO O ASIMMETRICO


io farei cmq un test di bandwidth per assicurarmene.

facci sapere.

come ti diranno anche altri ti consiglio di andare per popolare i canali con moduli della stessa dimensione dato che è molto probabile altrimenti che si attivi il dual-channel asimmetrico

Dual-Channel Asymmetric
This mode is entered when both memory channels are routed and populated with different
amounts (MB) of total memory. This configuration allows addresses to be accessed in series
across the channels starting in channel A until the end of its highest rank, then continue from the
bottom of channel B to the top of the rank. Real world applications are unlikely to make requests
that alternate between addresses that sit on opposite channels with this memory organization, so
in most cases, bandwidth will be limited to that of a single channel.

Dual-Channel Symmetric
This mode allows the end user to achieve maximum performance on real applications by utilizing
the full 64-bit dual-channel memory interface in parallel across the channels with the aid of Intel
®
Flex Memory Technology. The key advantage this technology brings is that the end user is only
required to populate both channels with the same amount (MB) of total memory to achieve this
mode. The DRAM component technology, device width, device ranks, and page size may vary
from one channel to another.
Addresses are ping-ponged between the channels, and the switch happens after each cache line
(64 byte boundary). If two consecutive cache lines are requested, both may be retrieved
simultaneously, since they are guaranteed to be on opposite channels.
