• Supports dual channel DDR 266/333/400, using four 184-pin DDR DIMMs.
• Supports a maximum memory size up to 4GB without ECC.

to znamena fungovalo by aj 2 x 1GB, ale kedze to ma 4 sloty tak pridanie 2x512MB ako pisal uz host bude asi lacnejsie. Potrebujes PC3200 (DDR, ne DDR2, ne DDR3), nove uz mozno nezozenies ale pozri si shopy mozno este maju DDR. Vymenit to zvladnes, klucove su len 2 packy na bokoch slotu.
