Bump.
I might also add a question about Bank and Channel interleaving. As far as I read on forums, it improves performance. Why is it all off by default? Also MemClk Tristate - still got no idea what it is. And I think the Q about Enable Clock to all DIMMS stays open, cause you actually never set clock separately anyway. Shoud be something else..

(from the PDF of my mobo manual): "This item determines whether the BIOS should actively reduce EMI (Electromagn etic Interference) and reduce power consumption by turning off unoccupied or inactive DIMM slots."
Other respondents have this option mixed up with something that is sometimes called "DRAM Timing Mode," which is the option that allows you to select auto timing, or manual timing options via DCT0, DCT1, or BOTH.

2:memclk tristate:
I'm under the impression that when this is enabled, the dimms can be put in a low-power-state while the computer is suspended/sleeping. There may be more to this, hard to find good information about it.

3:dct unganged mode:
While others have explained this fairly well, the more important point to be made, is that unganged operation allows dual channel support even on dimms of unequal capacity when possible.

4:memory hole remapping:
(Again from the PDF of my mobo manual): "This item allows you to enable or disable the remapping of the overlapped PCI memory above the total physical memory. Only 64-bit OS supports this function."
I have no reason to believe this has anything to do with being able to address more than 3GB of RAM.

5: Bank Interleaving:

6: Channel Interleaving:
(from: http://www.hardwarecanucks.com/forum/ram/36978-channel-interleave.html )"Channel Interleave: Channel Interleave: Higher values divide memory blocks and spread contiguous portions of data across interleaved channels, thereby increasing potential read bandwidth as requests for data can be made to all interleaved channels in an overlapped manner. For benchmarking purposes when using three memory modules, a 4-way interleave may surpass the scoring performance of setting 6-way interleave depending on the benchmark and operating system used (32-bit vs. 64-bit). We did find however that a 6-way interleave was capable of a higher overall BCLK for Super PI 32M than using a 4-way interleave setting (unless of course you run single- or dual-channel and appropriate channel interleaving thus decreasing load upon the memory controller)."

Thank you! Man, where were you 1 year ago?
