Speed DDR2 667 (PC2 5300)

  • 8GB total capacity from four 2GB modules
  • DDR2 667MHz speed rated at PC2-5300
  • 240-pin DIMM form factor fits standard desktop slots
  • Non-ECC unbuffered design for broad motherboard compatibility
  • 8V standard DDR2 voltage for stable operation

Kit composition

This A-Tech kit supplies eight gigabytes of DDR2 memory across four 2GB modules. It targets owners of legacy desktop systems that require 240-pin DIMM slots and standard 1.8-volt operation. The unbuffered, non-ECC design suits typical consumer motherboards rather than server platforms.

Sustained load behaviour

Each module runs at a tested 667 MHz with CL5 timing, delivering steady PC2-5300 bandwidth during extended workloads. Major-brand chips and factory quality testing help maintain error-free operation when the system handles heavy multitasking or large datasets over long sessions. The quad-channel population can saturate supported chipset bandwidth more evenly than smaller kits.

Compatibility checklist

Verify that your motherboard accepts DDR2 DIMMs at 667 MHz and provides four free 240-pin slots for the full kit. Confirm the board supports unbuffered, non-ECC modules at 1.8 volts and can run all slots populated without downclocking. Check the vendor’s qualified-vendor list for the NE-SS-0621 part number before ordering.

Questions about this item

Will this kit fit a motherboard that only has two DIMM slots?

The kit contains four 2 GB modules, so it requires four available 240-pin slots. If your board has only two slots, you would need a two-module kit instead.

Is this memory compatible with systems that require ECC registered modules?

No. These are non-ECC unbuffered DIMMs, so they will not work in platforms that demand ECC or registered memory.

What voltage do these modules run at, and is it standard for DDR2?

Each module operates at 1.8 V, which is the standard DDR2 voltage, so no special voltage settings are needed.
