What this kit does

This 4 GB kit contains two 2 GB DDR2 800 SO-DIMM modules built for the Apple iMac "Core 2 Duo" 2.8 24-Inch Early 2008. It restores or expands memory on that specific model when the original sticks are missing or faulty.

The spec that decides fit

The modules are 200-pin PC2-6400 DDR2 running at 1.8 V with CL6 6-6-6 timing and unbuffered 2Rx8 organisation. Only systems that accept this exact DDR2 SO-DIMM specification will recognise the memory.

Install notes and common issues

Installation requires opening the iMac memory door and seating both sticks firmly until the latches click. The machine has two slots and a 6 GB maximum using mixed 4 GB and 2 GB modules, so this 2x2 GB kit leaves one upgrade path open. Buyers needing more than 4 GB total capacity should look elsewhere.

Compatibility confirmed

Computer Memory Solutions guarantees operation with the listed iMac model identifiers MB325LL/A, iMac8,1 and A1225. The kit ships as a matched pair from a major brand chipset source and carries a limited lifetime warranty from the manufacturer.

商品問答

What does the 800 MHz DDR2 rating deliver in an iMac 24-Inch Early 2008?

The kit runs at 800 MHz with CL6 timing, matching the iMac's memory controller and providing 4 GB total across two 2 GB modules.

Which slot type does the 200-pin DDR2 SO-DIMM use and what maximum capacity does the system allow?

The modules fit 200-pin DDR2 SO-DIMM sockets; the iMac supports up to 6 GB using one 4 GB and one 2 GB stick.

What physical clearance do the two 2 GB sticks need inside the iMac?

Standard-height SO-DIMM sticks without heat spreaders install directly into the two memory slots behind the bottom access door.
