This memory is manufactured by a major memory producer to provide you with the trust and quality that you can expect from HiTech Vendors.
To take advantage of today's more powerful processors, we recommend PC133 memory. This 8 nanosecond memory is certified to run with 133MHz bus speeds. It matches today's high-megahertz processors stride for stride to give you maximum performance and speed. Surf faster, run more problems simultaneously, run memory-hungry applications easily. PC133 is the smart choice.
NOTE: Please consult with your computer manual or physically looking at your memory and make sure if you are in need of double-sided or single-sided memory.
i.e., If there are 8 black chips on both sides of your memory sticks, you need double-sided memory.
Please note which type you need in the comments section of your order.
