Each memory is subjected to various types of manual testing, enabling the product to be used in different application environments, providing users with both high performance and high stability of the computer experience. CL9 corresponds to 1333MHZ, each memory frequency corresponds to a different CL value. Product description: 8GB 4GB DDR3 (DDR3=1333MHz /1600MHz /1866MHz),CAS Latency:1333MHz=CL9 1600MHz=CL11 ,Original Chips,For HY SEC ELP MIC... Dual Channel Support,DDR4=1.2V,DDR3=1.5V Superior quality and best price,Unbuffered, Non-ECC, Non-Registered Fully tested Three Years Warranty The Recognition of XP is around 3GB The Recognition of Win 7 32Bit is around 2.26-3.5GB For 1866Mhz, Below is test from CPU-Z. It will shown PC3-14200(889Mhz). It will not shown PC3-14900. NOTE: 1.8gb DDR3 only the motherboard with the highest configuration can be used. (Motherboard is bigger than H61 to use 8GB for Intel RAM) 2. we show the photo of the color the products, pictures for reference only, subject to our available products. 8g ddr3 has single sided particles and double sided particles, we will deliver them randomly, thanks for your understanding! Why is my bios or diagnostic program (like CPU-Z) showing that my ,Is the memory running at half the frequency? The bios or diagnostic program usually reports the memory bus frequency which is half the frequency for ddr type memory.DDR (Double Data Rate) The data rate provides twice the memory bus frequency.So if the memory bus speed is 800mhz and you are using DDR3-1600 memory then the ram is running at the correct speed.
