2-power 2P-B4U36A6 - 4 GB - 1 x 4 GB - DDR3 - 1600 MHz

When a small office desktop starts lagging during multi-tab browsing or a home PC struggles with photo editing, this 2-Power 4GB DDR3 module restores smooth performance. It’s a straightforward upgrade for older Intel or AMD systems that still rely on DDR3 memory, bringing a single 4GB stick rated at 1600MHz to the board.

Key specifications

• Capacity: 4GB (1 x 4GB module)
• Memory type: DDR3
• Speed: 1600MHz (PC3-12800)
• Form factor: 240-pin DIMM
• CAS latency: CL11
• Voltage: 1.5V
• Error correction: Non-ECC
• Buffering: Unbuffered
• Rank: Single rank (1Rx8)
• Application: Desktop PC
• Heat spreader: No
• Compatibility: Intel and AMD platforms

Why choose it

It’s a cost-effective way to extend the life of a DDR3 desktop. The module follows JEDEC standards, so it drops into most mainstream boards without BIOS tweaks. With 1.5V operation, it runs cool and efficient, and the unbuffered design ensures low latency for everyday tasks.

Ideal use cases

• Upgrading an office PC from 2GB or 4GB to 8GB total
• Replacing a failed memory stick in an older workstation
• Building a budget home server or NAS with spare parts
• Improving responsiveness in Windows 10 or Linux desktops

Good to know

This is a single module, so you can add it to an empty slot or pair it with an identical stick for dual-channel operation. It does not include a heat spreader, which is typical for standard DDR3 and helps with clearance in compact cases. Always verify your motherboard supports 4GB unbuffered DIMMs at 1600MHz before purchase.
