Computer Repair Training Plus hardware lesson 1-3 we discuss the newer Intel Core i7 design. This new Intel Quick Path design moves the memory controller from the north bridge to the CPU. This move more than doubles the bandwidth and also provides a separate channel for
the memory. Also the I/O controller bandwidth has more than doubled. We compared this to the older design showing the bandwidth limitations and possible bottlenecks. This new design should eliminate any of the bottlenecks that existed in the older design.
It’s amazing to see this technology moving forward at such a fast pace. Robotics and AI are advancing with these processing improvements and should help to further automate all industries. The wife and I love our Romba’s and we enjoying how diligent they are in keeping our house clean.

I also made a YouTube video concerning the motherboard and the new Quick Path Core i7 improvements.
The Computer Repair Training website has some additional information you might find helpful.
RAM and video are directly connected through the North Bridge (NB) and directly determine the performance of the computer. You need fast RAM memory and a good video card to prevent data bottlenecks. Intel has recently moved the memory controller off the north bridge and onto the CPU. This move allows the CPU direct access to the RAM and has greatly improved performance. The south bridge controls all the other I/O connections and can run considerably slower. Most computers today have dual channel memory which has helped feed the faster CPUs. However, take advantage of the two channels you should be splitting your memory so if you want 4GB of RAM you will put 2GB in each channel. The memory should also be rated and matched for dual channel. The Newer Core i7 CPU uses DDR3 triple channel and again to get the benefit you would split the memory over all three channels. The only area left to catch up is the hard drive. New faster solid state drives will eventually help bridge this gap.
PCs by Scott Mueller, and A+ Guide to Managing and Maintaining Your PC by Jean Andrews are some of my favorites. These books can be found at Amazon and eBay. I have found some of the older versions sell for a lot less and still contain most of the information that you will need to learn. The technology has been rapidly improving over the years but the basics have stayed the same. For example, floppy drives and ATA hard drives operate the same as they did 10 years ago with only a few bandwidth improvements. However, the newer SATA and solid-state drives are a much needed improvement.
technician certification throughout the world. Passing the two tests for certification will open many doors to the computer maintenance field. Many employers make the A+ a prerequisite for getting an interview. CompTIA is a vendor neutral nonprofit organization and has developed a set of exam objectives that we will cover during this course. The objectives can be viewed at the CompTIA site and comprise the following categories; hardware, operating systems and software, networking, security, troubleshooting, repair and maintenance, and operational procedures. Each category is weighted differently with hardware having the highest weight followed by operating systems and then troubleshooting.
