HP Business Desktop DX2000 series upgrade

This 2 GB kit contains two 1 GB unbuffered DIMMs built for HP Business Desktop DX2000, DX2025, DX2030 and DX2090 systems. The modules run at DDR400 speed with CL3 timings and 2.6 V operation. They are designed as a direct memory upgrade for those specific desktops.

Installing the matched pair

The supplier notes that modules must be ordered and installed in pairs to enable dual-channel mode on these platforms. Each stick uses a standard 184-pin DDR SDRAM edge connector that fits the desktop's DIMM slots. No heat spreader is present, so clearance inside compact chassis is not affected.

DDR1 platform limits

The DDR1 interface tops out at 400 MHz with a maximum bandwidth defined by the PC3200 standard. Capacity per module is limited to 1 GB in this kit, so total memory cannot exceed the motherboard's supported maximum. Older chipsets also require paired population for dual-channel operation.

Questions about this item

How can I confirm the CM128643200DIMM kit is running at DDR400 after installing it in my DX2000?

Enter the BIOS on the DX2000 and verify the memory frequency shows 400 MHz with CL3 timing. The system should also report the full 2 GB capacity across both slots.

What exactly ships with the CM128643200DIMM package and do I need any extra parts for my DX2025?

The box contains two 1 GB 184-pin DDR1 DIMMs. No additional modules or accessories are required for the DX2025; install the pair in matching slots for dual-channel operation.

Which capacity version of this CMS memory should I choose for a DX2090 that supports up to 4 GB?

This 2 GB kit (2 x 1 GB) is the correct version for the DX2090. It fills two of the four slots and leaves room for a second identical kit if you later want the maximum 4 GB.
