Hello mohamadg, you need to clarify your question. Flash memory looks like the memory shown on the site below; (Click on the link).

(I think your question pertains to system memory)!
System memory for the Asus motherboard looks like this;

Your Asus motherboard can only function with, DDR2-800MHz / 667MHz or 533Mhz (Only). Dual channel 4x240 non-ecc memory. You can run up to 8 GB max of memory. If the system memory you are currently using does not match the above type & speed, your motherboard will not function. You will hear a series of beeps during start up of the system. These beeps are known as bios beeps. How many beeps (Including long beeps & how many short beeps you might hear) will tell you what is most likely wrong with your system memory. (See the next link for the Award bios beep codes);

Dual channel memory should be bought in pairs & not as a single stick/DIMM. Do not install more than 2GB of system memory until windows has been completely updated through (Windows Update Services). Once Vista or any version of windows has been fully updated you can increase your system memory. You can not mix memory speeds & type. If you are using 533MHz memory, & you want to increase the total memory to be used, you must match the memory speed of 533MHz. All system memory must be the same speed & type. See page 2-10 in your manual. Running two different types of memory may not give off bios beeps & the system may not function at all.
