1. Testing PC Performance
Introduction
I am going to test a PC to check its performance of CPU and RAM when applications are
being used.
Why?
I will be doing this to improve the PC performance of a customer’s computer and to help
them get the performance they need out of their PC.
Where?
I will be getting the data from the Performance monitor and Treesize. Performance Monitor
will be used to get CPU Usages

To test the Performance I ran Windows Performance Monitor and opened up a variety of
applications such as Chrome, Google Mail, Ran Photoshop, Opened Word and Played audio and
video files to test the Performance.

4. Introduction
I am going to check the disk space to see how much usage is being taken up, because this
may cause the hard drive to perform slow and even cause the computer not to print.

From the results I can see that over 50% of the used space is taken up by the OS.

5. Task 3 – Should I upgrade?
In this task I will be checking the current machines system and then deciding wherever I
should folk out the money and upgrade the machine.
CPU: Intel Pentium Dual Core G640 2.8GHz
RAM: 6GB DDR3
HDD SPACE: 500GB
GRAPHICS: Onboard Graphics
OPERATING SYSTEM: Windows 7 Professional Service Pack 1 (Build 7601)
MOTHERBOARD: Gigabyte H61M-S2PV
Upgrade Option
Max Memory:
The max memory this machine can currently take is 16GB. Crucial Memory is recommending
that I take the 4GB stick and the 2GB Stick and replace it with 2 x 8GB Sticks. To do this I will
need to upgrade the current operating system to 64bit because 32bit only supports a
maximum of 4GB.
•
Price for OS: £72.56
•
Price for 2 x 8GB Sticks: £190.79
Max Processor in same socket:
The max processor in the same socket would be an Intel Xeon E3-1290 V2 @ 3.70GHz. This
processor currently scored 9942 on CPU Benchmark. I didn’t choose this processor because
it’s a server processor and it’s an expensive processor.
So I opted to go with the Intel Core i7 3770k.
Price for Intel Core i7 3770k: £240
Labour Charge: £30 an hour (2 hours)

Advantages: If you upgrade your current machine you will end up saving a little bit of cash
roughly around £40, which isn’t a huge saving. But it still means you save some money.
Disadvantages: If you’re only saving £40 you may as well folk out the extra £40 and get a
brand new £600 build and have a machine with a better life expectancy than your current
machine.
