Can you tell me what is the difference in performance without having Dual-Channel working as it should,compared to my present situation meening NO DUAL-CHANNEL working??

Dual channel means two channels of memory. there are two configurations you can use. you can use single channel method which has twoo ram sticks running on one channel or you can have a seperate channel for each ram stick. Dual channel is said to be the better way to run it because it increases speed of the ram. Now assuming you have 4 slots for ram. to use dual channel you have to run 2 sticks of the same value (MB) right next to each other. You cannot run 2 sticks of different values in dual channel mode. In the case that you do the sticks would pair together on a single channel. Hope this helps you better understand.

Yes I know that order into whitch slots i should put the memory stics,1 and 3 or 2 and 4 but CPU-Z isshowing me everytime that the mobo is running in sinle mode?????

CPU-Z might mean that your computer is running in "Single" Channel. Running in dual channel mode is slightly faster. Maybe 5% or a little more. To run dual channel you need 2 sticks of identical DDR ram. Your PC might have 2 non-identical memory sticks that's why it runs in Single Channel.

What is better? to put four different rams or one single ram of 4gb in p4p800 vm asus motherboard

I would suggest going with a single piece or 2 identical pieces of RAM for expandability purposes. If you want to upgrade later, you will have the option to add more RAM. From a cost standpoint, you might be better off buying 2x 2GB sticks as a single 4GB stick of RAM might well exceed the cost of 2x 2GB sticks.

Dual channel Mode willnot work over 2 gb's of

Hi, please read page 12, section 2.3 in your manual. Dual channel memory must be connected per manual specs.
(Correct colored DIMM slots)
Link to Asrock manual;
Main web site provided by Asrock;

Once the memory is installed into the correct colored DIMM slots your system should see up to just under 4GB if 4GB is installed while using windows XP. (Refer to Asrock's web site).

Hope you find this helpful and working.

Nforce4-a939 board ,my system shows single channel 64 bit but on perchasing it was dual channel 128 bit how can i fix it......

The 128-bit mode is achieved by putting _matching_ sticks of RAM in the RAM-slots. Non-matching RAM will run as "single-channel" (64-bit) mode.

Matching RAM must have the _same_ amount of RAM per stick,
and the same internal "timing" parameters (look closely at the RAM for strings like 3-2-2 or 2-2-2-2).

If you have exactly 2 RAM slots on the motherboard, matching RAM will always run in "dual" mode.

If you have matching RAM, and you have 4 RAM slots, put one stick of RAM in slot #1, and one in slot #2, and leave #3 and #4 empty. Start it up, to see if it is using "dual" mode.

If not, shutdown, power-off, and move the RAM from slot #2 to #3, and start it again. This time, it will run in "dual" mode.

Ram problem

1)not all rams are dual compatible 2)did u try both sticks separately? (1 may be damaged) 3)are they exactly the same? CAS, voltage, etc..? Sometimes different CHIPS cause trouble 4)try changing to 333 mhz if it works, go back to 400 and try either CAS 3.0 (assuming auto is 2.5 or lover) if not working yet, try the "T" seeting to "1". If your BIOS doenst show this setting and is AWARD, after getting into it with DEL, press CTRL+F1 and then look which setting came from the dark... (hidden settings) on Gigabyte boards for ex. it has to be done.
