System-specific DDR1 upgrade

This 2GB kit contains two 1GB unbuffered DIMMs built for Dell Dimension 4600 and 4600C desktops. Each module runs at DDR400 speed with CL3 timing at 2.6V. The 184-pin design matches the original memory slots in these systems.

Sustained load behaviour

Under continuous operation the non-ECC modules rely on the system board for error handling. The 3-3-3 timing and major-brand chipset maintain stability at the rated 400MHz frequency. Heat spreaders are not fitted, so airflow inside the chassis determines thermal performance.

DDR1 interface limits

The DDR1 standard tops out at 400MHz and 2.6V for unbuffered DIMMs, so this kit reaches the ceiling of the technology. Builders needing more than 4GB total capacity or registered memory support cannot use this platform.

Questions about this item

How much power does this 2.6 V DDR1 kit draw when the system runs all day?

Each module operates at 2.6 V, the standard voltage for DDR 400 memory. Actual power draw depends on the motherboard and workload, but the kit adds no extra heat spreader.

What must the motherboard provide for these two 184-Pin sticks to function?

The board needs two free 184-Pin DDR DIMM slots that accept non-ECC, unbuffered DDR 400 (PC 3200) memory at 2.6 V.

Will the CL3 timing on this kit match the latency of the original Dell memory?

The modules run at CAS latency 3 with 3-3-3 timing, which is the standard timing for DDR 400 PC 3200 memory.
