Hey, im wondering if this memory module is compatible with this motherboard
Memory:
http://uae.dtcae.com/product/twinmos-2gb-ddr2-desktop-ram-4617/
Motherboard:

The motherboard which you have given is custom built and used in Dell Dimension E520 systems. So could you confirm if you have the same system?
If you have the same model then try getting the memory from other vendors as I don't know much info about the site you mentioned. Check for PC2-4200/5300/6400 DDR2 Non-ECC DIMMs. Supported Sizes 1GB, 2GB and 512MB. You can upgrade upto 8GB and it has 4 slots.
Check
Memorystock.com (they have UAE shipping if you are from the same place) even Crucial has shipping. Or get it locally from one of the hardware stores.
Good luck with the memory upgrade.
