Hello

Hello

• Operating System: Windows XP pro sp3, 32 Bit

• G31 board with E6300

• 2 x 2 GB 800 MHz RAM

Problem: Everest Ultimate Edition shows rams (2 x 2GB) are running (dual channel mode) at 64 bit Mode, whereas 2 x 1GB running at 128 bit mode. Please tell me the reason.

Thanks

This is correct and desired mode of operation for dual channel memory, and is preferred to 1x128 bit. The AMD equivalent is 'unganged', where each bank is operated in independent mode.

What exactly is the problem?

are those 2GB sticks identical (read same model number and specifications) ??!!

sticks are identical. My problem is - Everest Ultimate showing 2 x 1GB 667 MHz ram at 128 Bit whereas it shows 2 x 2GB 800 Mhz running at 64 Bit.

Why!! I think 800 MHz rams are not running at Dual Channel i.e., 128 bit.
All DDR2 RAM sticks are 64 bit. So running two RAM sticks at Dual channel 64 bit x 2 = 128 bit.

Dual channel means two separate channels, so each channel retains 64 bit word width. When you put both the sticks on the same channel you get 128 bit bus width.

Dual channel = 2x64 bit

Single channel = 1x128 bit.

You can choose whichever you prefer. You cannot get 2x128 bit, which is what you seem to be thinking. You can, but then you need four channels of RAM control (such as in video cards).
