Ram Numbers Explained


DDR - Double Data Rate memory - a type of DRAM based on SDRAM technology that operates at twice the bus clock rate. The real life examples were 2-3-3-8 and 2-3-2-6 both of which are good for DDR at 400MHz, but I can now see that the Mushkin 2-3-2-6 RAM may be more stable Image Credits: William Hook Previous Post3 Ways For New Players To Enjoy Eve Online For FreeNext Post3 Cross Platform, Free Word Games For Android and iOS Users To Compete On 11 LRCD Row Address to Column Address Delay - tRCD is the number of clock cycles taken between the issuing of the active command and the read/write command.

For example the front-side bus (FSB) transports data between the CPU and the Memory Controller (and to other destinations). ECC - Error Correcting Code - RAM that has additional data storage for checksum bits to allow correction of errors 'on the fly'. Heat Spreader - A thin metal cover making thermal contact with the memory chips and assisting in cooling. This information can be found in the same location as the maximum amount supported (mentioned above).

That is another advantage of memory modules sold specifically for overclocking. Static Precautions When handling RAM, as with other computer components, care needs to be taken to avoid damaging the component through the discharge of static electricity that builds up on your Some will have no label at all in which case you would have to track down information on individual memory chips using the part numbers printed on them. The best way to combat static while working inside your computer is to wear a static strap attached to the chassis and worn on your wrist during the whole process.

On my own system I have American Megatrends Inc. If you have different speeds, such as one stick of 1333 and one stick of 1600, all your RAM automatically will run at the slower speed -- in this case, 1333. For historical purposes, here are the details for using too much ran in older systems. How To Read Ram Specs Following that process is beyond the scope of this tutorial.

How is it defined? This will indicate for example whether the Memory Controller can support Dual Channelling, which you will need to consider if you are upgrading. Do the same thing for any other RAM modules to install and you're done. http://superuser.com/questions/315346/how-do-i-interpret-the-specification-of-memory-ram When to enable 'On the fly' CRS transformation in QGIS?

RAS Precharge time (tRP) is the time taken between when the Precharge command and the next Active command can be issued. How To Identify Ram Type Physically Everest Memory Module Properties Additional information about the Memory Controller can be found in the 'Motherboard' window by clicking on 'Chipset' and highlighting 'North Bridge'. If you get it wrong you can still use all your RAM but you won't have the speed benefit of Dual Channelling. This will run the program and present you with a report window which looks like this: CPU-Z Opening Screen We're interested in the RAM at present so click the 'Memory'

Understanding Ram Labels

A good SSD is going to have an access time of around 100 microseconds (100 millionths of a second), compared to around 10 milliseconds (ten thousandths of a second) for a It does this by issuing (in binary) an "address" for the Row and then the Column using the same 11 bit address bus in each case (because it takes 11 bits Ram Numbers Explained The second is the speed in MHz that the memory operates at, in general the faster the better (to a point) Timing: The numbers are the number of wait cycles that Ram Specifications Explained up vote 0 down vote Speed: The first part is the type of memory.

It usually is T1 (1 clock cycle) or T2 (2 clock cycles). Latest DDR2 is designed for 800MHz operating speed. Rimmer March 2006. US Charges Four Hackers in Yahoo 2014 Security Breach, Including Two FSB Agents Ask.com Toolbar Network Compromised Twice in Two Months US-CERT: Security Products That Perform HTTPS Interception Weaken Security New How To Read Kingston Ram Label

For example, even though you may achieve 1,600 MHz (800 MHz x2) with DDR3-1333/PC3-10600 modules, on these modules it may be necessary to increase the memory timings, while on DDR3-1600/PC3-12800 ones the manufacturer You only have so many DIMM slots. Your computer needs different amounts of RAM for different tasks and the more applications you open the more RAM is required. This extra bit of data is called the 'Parity Bit'.

Click on the 'Info' tab and click the 'Read info' button. Ddr3 Ram Specifications https://www.bleepingcomputer.com Users who read this also read: Using Windows ReadyBoost to Increase Performance in Windows 8, Windows 7, and Windows Vista Have you ever had an experience where you are using Some versions of the Award BIOS slow down your system markedly when more than 768MB of RAM is installed.

This is called disk thrashing and it is when you have run out of physical RAM and instead Windows is using a file on your hard drive to act as a

Similarly the RAM itself has a maximum speed at which it can reliably operate and this must be at least as high as the memory bus speed. What do these terms mean, and how do they affect the systems performance? If you have the option for getting two sticks over one, go for it, but only if the price is similar. How To Check Ram Specifications See here for more info on these and other RAM timing elements.

There are appropriate uses for this type of computer (e.g. In this time the sense amps charge and the bank is activated. Numbers like 7 or 75 depict 7ns and 7.5ns RAM and are pc133. Data Sheets: Click to View Mitsubishi Ram Manufacturers Symbol: MITSUBISHI Manufacturer Name: Mitsubishi Electric & Electronics Inc.

Original RIMM modules were PC600, PC700 and PC800 speeds. Since the manufacturer guarantees that these modules will run up to 2,133 MHz, you know that you can raise the memory bus clock up to 1,066 MHz to achieve a higher Here is an example. Why not stick with one type?

Not enough and it can't power the module, too much and you can damage the various chips on the module.
