Introduction: Ram Instruct Able
RAM is used by the central processing unit (CPU) when a computer is running to store information that it needs to be used very quickly, but it does not store any information permanently.
Step 1: Types of Ram
SDRAM (Synchronous DRAM) 168-pin SDRAM DIMMs. SDRAM is not an older version of EDO DRAM but a new type of DRAM altogether. SDRAM started out running at 66 MHz, while older fast page mode DRAM and EDO stop out at 50 MHz. SDRAM is able to scale to 133 MHz (PC133) officially, and unofficially up to 180 MHz or higher.
DDR (Double Data Rate SDRAM) DDR doubles the rate in which data will transfer standard SDRAM by transferring data on the clock cycle. DDR memory actually operates at 166MHz * 2 or 133MHz*2 . DDR is a 2.5 volt technology that uses 184 pins in its DIMMs. It is incompatible with SDRAM physically, but uses a similar parallel bus,
Rambus DRAM (RDRAM)
Besides being a higher price, Intel has taken a step ahead, and it will be the sole choice of memory for Intel's Pentium 4. RDRAM is a serial memory technology that arrived in three different types, PC600, PC700, and PC800. PC800. RDRAM has double the maximum that the old SDRAM could achieve, but a higher latency. RDRAM was designed with multiple channels, DIMMs vs. RIMMs DRAM comes in two major form factors: DIMMs and RIMMS. DIMMs are 64-bit components, Typically, if you want to add DIMM memory to your machine, you just pop in a DIMM stick (if you have an available ram slot ) . DIMMs for SDRAM and DDR are different, and not physically compatible. SDRAM DIMMs have 168-pins and run at 3.3 volts, while DDR DIMMs have 184-pins and run at 2.5 volts.
RIMMs use only a 16-bit interface but run at higher speeds than DDR. To get maximum performance, Intel RDRAM chipsets require the use of RIMMs in pairs over a dual-channel 32-bit interface. You have to plan more when upgrading and purchasing RDRAM.
Step 2: Memory Clock Speed
SDRAM at stock is a speed of 66MHz. As technology got better and more innovated the buses got faster, it was later clocked to 100MHz, and even 133MHz! speed grades are identified as PC66, PC100 and PC133. Some manufacturers are shipping a PC150 speed grade. However, this is an unofficial speed rating, and of little use unless you plan to overclock your system.
Step 3: Maintenance of RAM
Making sure all ram is kept clean by using compressed air and Q-tips to clean to make sure everything can come off
Ram can also be check by going through task manager and checking the processes it shows usage and how much is there Stress tests can be used on ram to make sure that it is fully working
Step 4: Possible Issues That Can Occur Due to Ram
1. Windows will freeze for minutes at a time regardless of what application you are using. It may take 2 minutes to open Word or 3 to 4 minutes to open IE. Usually, performance issues are the first to appear and can easily be misconstrued as a virus or malware.
2. You get the infamous blue screen of death, but without having added any new hardware or installed any new software. If you’re getting the blue screens and haven’t installed any new drivers or Windows updates, it could be a memory issue causing the blue screen.
3. The PC restarts randomly while you are in the middle of doing something. Random restarts can also be attributed to a lot of different factors, but if you are having this problem in combination with any of the other mentioned, then it’s more than likely a RAM issue.
4. You start to notice files becoming corrupt on your system. If you’re working with a lot with certain files and notice that they are not saving properly or the data is being corrupted, you can narrow it down to the hard drive or memory. If you’ve run diagnostics on the hard drive and all is fine, then these read/write errors can be caused when parts of the file are stored in RAM.
5. You start to see strange colors or lines appear on the screen or things look garbled suddenly. Sometimes the memory issue can be so bad that the data being sent to the screen becomes corrupt and therefore displayed incorrectly.
6. When you boot the computer, you hear a beep, multiple beeps and a continuous beep. Depending on your manufacturer, a memory problem will be reported with a series of beeps. I’ve seen this a lot of Dell machines. It’s almost always a RAM problem when the computer beeps.
Step 5: How to Fix Possible RAM Issues
Testing each ram stick individually to see if the pc will start up with one and not the other
Getting new ram to see if this will resolve the problem
Windows memory diagnostic will help immensely as well
Using a ram stick that is known good and observing if it will work correctly
We have a be nice policy.
