Targeted DDR3 Kit for HP Business Pro 3500 and 3505

This 8GB kit contains two 4GB unbuffered DIMMs built to the DDR3 1333 standard with CL9 timing. It is designed specifically for the HP/Compaq Business Pro 3500 and Business Pro 3505 Microtower systems. The modules run at 1.5V and use a 240-pin layout with 2Rx8 organisation. Buyers who need ECC error correction or registered modules cannot use this kit.

DDR3 1333 Bandwidth and Platform Ceiling

The PC3 10600 interface caps theoretical bandwidth at the DDR3 1333 data rate, so throughput cannot exceed what the memory controller and chipset allow on these platforms. Both supported systems only provide two DIMM sockets and a maximum memory limit of 8GB, so this kit fills every available slot. Builders who want more capacity or faster speeds must change the platform entirely.

Direct Replacement for Factory 4GB

Most units shipped with 4GB or 6GB across the two slots, so this matched pair doubles or completes the memory to the 8GB ceiling. The jump is worth it when multitasking causes heavy paging or when the integrated graphics share system memory. If the system already runs 8GB, this kit adds no usable capacity.

Questions about this item

Should I pick the 2×4 GB kit or a single 8 GB stick for my HP Business Pro 3500?

The 2×4 GB kit fills both DIMM slots on the Business Pro 3500 and 3505 Microtower, enabling dual-channel operation for higher memory bandwidth than a single module.

What does the PC3-10600 rating mean for actual throughput in my system?

PC3-10600 indicates a peak transfer rate of 10 600 MB/s at 1333 MHz; real-world throughput will be slightly lower due to latency and controller overhead.

Does the 240-pin DDR3 interface limit the speed I can run these modules at?

The 240-pin DDR3 interface supports up to 1333 MHz on this platform; the memory controller in the Business Pro 3500/3505 caps operation at that frequency.
