Build Budget PC Less Than $300

June 2013

The date is important in regards to any quote. Recently I thought of upgrading an old PC used for some younger family members. The old PC was running an Athlon XP of early 2000s vintages. The PC itself has got a mixture of component.

The challenge is to build a PC for less that $300. As shown in the table below, this can be done. The prices are quoted from www.msy.com.au in Australian dollars. The actual components have prices listed in the Price column. The Alt column shows the prices of alternative PC components.

The key components that need upgrading are CPU, Motherboard, RAM, Hard Drive and Case. The cost limit is enough to include a CPU Fan. The main design is to have the budget Celeron CPU which has integrated ATI Radeon graphics. The motherboard is chosen to include some legacy PCI slots to use the existing wireless adapter card. The lack of grunt of the Celeron is made up by the whopping 8GB RAM. The old DVD writer can be reused. A modern PC Case would improve the image of this budget PC.

Detecting Cache and Memory Misses
===================================
To analyse cache miss, the following performance counters may help:
- Cache : Data Map Hits :
Percentage of Data Maps in the Cache that could be resolved without having to retrieve a page from
the disk, i.e. the page was already in physical memory.
- Cache : Fast Read Resource Misses /second :
Frequency of Cache misses necessitated by the lack of available resources to satisfy the request.
- Memory : Pages /second :
Number of pages read from the disk or written to the disk to resolve memory references to pages that
were not in memory at the time of the reference. This is the sum of Pages Input/sec and Pages
Output/sec. This counter includes paging traffic on behalf of the system Cache to access file data for
applications. This value also includes the pages to/from non-cached mapped memory files. This is the
primary counter to observe if you are concerned
- Memory : Cache Faults :
Occur whenever the Cache manager does not find a file's page in the immediate Cache and must ask
the memory manager to locate the page elsewhere in memory or on the disk so that it can be loaded
into the immediate Cache.


Detecting Processor Bottlenecks
================================
The symptoms of a processor bottleneck aren't difficult to recognize:
- Processor: %Processor Time often exceeds 90%.
- System: Processor Queue Length is often greater than 2.
- On multiprocessor systems, System: % Total Processor Time often exceeds 50%.
