Parity RAM and non-parity RAM
Question: How can I tell which kind of memory I have: parity or non-parity? – Colin
Answer: First, here’s how:
- Disconnect the computer’s power supply, then open the computer.
- Touch a metal part of the frame, to disperse any static electricity.
- Count the number of chips on each RAM module. RAM (or Random Access Memory) is located on the motherboard, which is the big circuit board inside the machine. The RAM is usually standing perpendicular in strips each about as long as a sticky of Juicy Fruit gum. If the total number of chips on each RAM module adds up to a number divisible by three, you need parity memory.
Your computer owner’s manual should also tell you. You can consult your manufacturer through a phone call or their website.
Now here’s a bit more about parity which I culled from PCguide.com: RAM traditionally has been available in two types: non-parity and parity. Non-parity is the most common. It contains one bit of memory for each bit of data that is stored. Eight bits are used to store each byte of data.
Parity memory adds an extra bit for every eight bits of data. It is used for error detection and correction.
