Computer Memory Solutions 8GB (2x4GB) DDR2 800MHz CL6 1.8V 240-pin DIMM Kit

SKU CH-0W5E-7AW7J

8GB dual-channel DDR2 kit with two 4GB 800MHz CL6 unbuffered DIMMs validated for Asus P5Q Premium and P5Q Pro motherboards

  • Capacity8GB (2 x 4GB)
  • Type240-Pin DDR2 SDRAM
  • SpeedDDR2 800 (PC2 6400)
  • CAS LatencyCL6
  • Timing6-6-6
  • Voltage1.8V
  • 8GB dual-channel kit doubles usable bandwidth
  • CL6 timing at 800 MHz cuts latency
  • 8 V DDR2 modules reduce power draw
  • Tested for ASUS P5Q Premium and P5Q Pro
  • 240-pin unbuffered DIMMs install in matched pairs

Targeted DDR2 upgrade kit

This 8 GB kit supplies two matched 4 GB DDR2 modules rated at 800 MHz with CL6 timings and 1.8 V operation. It is built for owners of Asus P5Q Premium or P5Q Pro motherboards who need to reach the board's 16 GB maximum capacity.

Unbuffered non-ECC DIMMs

Each stick uses a standard 240-pin DDR2 form factor without a heat spreader, keeping the profile low for tight CPU cooler clearances. The modules must be installed in matched pairs to activate dual-channel mode on the supported platforms.

Paired modules for dual-channel

The kit includes two sticks so the memory controller can run in dual-channel configuration immediately. A 64-bit operating system is required to address more than 4 GB, and the system may report only 3.5 GB usable when 4 GB is installed depending on memory allocation.

商品問答

Does the DDR2 800 (PC2 6400) standard cap the memory bus at 800 MHz?

Yes, the kit runs at DDR2 800 which is PC2 6400, so the bus operates at 800 MHz.

Will the 240-pin DIMMs fit the four slots on an Asus P5Q Premium or P5Q Pro?

Yes, these are standard 240-pin DDR2 DIMMs and the P5Q Premium and P5Q Pro each have four DDR2 slots.

Why must the two 4 GB modules be installed as a matched pair?

The board requires modules to be ordered and installed in pairs to enable dual-channel mode; otherwise it will run in single-channel.
