What Do The Numbers On The Ram Chips Mean?


Bus - A group of electrical conductors linking different parts of the computer. More RAM is only necessary if the system actually needs more RAM; there's no subjective difference in user experience on a Windows machine between a machine with 8GB RAM and one Introduced in 1999. rubrct2 · 9 years ago 0 Thumbs up 2 Thumbs down Comment Add a comment Submit · just now Report Abuse all it is is ddr2 ram @ 333mhz this is

Why is RAM important? RAM Timings are numbers such as 3-4-4-8, 5-5-5-15, 7-7-7-21, or 9-9-9-24, the lower the better. RAS to CAS Delay or tRCD measures this time. Not compatible with DDR motherboards.

Ram Numbers Explained

And if you have any questions, please don't hesitate to comment below. As long as everything you’re doing on the computer takes up less RAM than your total, you’re OK. Reply likefunbutnot October 23, 2013 at 3:57 pm 1 - 2x4GB or best of all 1x 8GB. Numbers like 7 or 75 depict 7ns and 7.5ns RAM and are pc133.

See here for more info on these and other RAM timing elements. Assuming you’re not doing anything especially bandwidth-intensive with your computer, it’s probably safe to settle on 1600 for DDR3 RAM. The third number (2) is TRP, the RAS Precharge delay. How To Read Ram Specs While looking around their site I was able to dig up even more info on my "can I have 64megs of 133Mhz RAM, please".

This activation is done by two control signals called RAS (Row Address Strobe) and CAS (Column Address Strobe). But you really only need to think about getting 16 gigs or more if you have a specific use in mind. KM48V2104ALT-6 ^^^---------------- KM4 = Samsung / SEC KM48V2104ALT-6 ^-------------- V = 3,3volt / C = 5volt G = SGRAM: Click here KM48V2104ALT-6 ^-^------------- Internal Organization: 4-256= 1Mb 256k x 4 : So, this DDR3-1333 memory would delay 10.5 ns to start delivering data if it had CL =7, or 13.5 ns if it had CL = 9, for example.

Hold the module close to and centred on the slot and check the notch in the RAM module lines up with the "key" in the slot to make sure you have How To Identify Ram Type Physically If I had more than one stick there would also be information for DIMM #1, DIMM #2, etc. Put any removed modules in the RAM container, take off your static strap, close the computer case and reconnect the power. It's likewise disingenuous to suggest that even a hard core PC gamer currently needs more than 8GB RAM - even AAA titles really don't exceed a 2 - 2.5GB memory footprint,

Understanding Ram Labels

For instance, DDR400 memories work at 400 MHz at the most, DDR2-800 can work up to 800 MHz, and DDR3-1333 can work up to 1,333 MHz. http://www.pcstats.com/articleview.cfm?articleID=179 No-one likes a slow computer so what do you do about it? Ram Numbers Explained All rights reserved. Ram Specifications Explained As for the latency, I'm wondering if the difference is not just small but negligible.

DDR - Double Data Rate memory - a type of DRAM based on SDRAM technology that operates at twice the bus clock rate. Reply Keegan October 22, 2013 at 3:29 pm 3.2gb RAM? If you're new to Tech Support Guy, we highly recommend that you visit our Guide for New Members. If Windows will not boot you can use the bootable disc made with Memtest-86 to test the memory. How To Read Kingston Ram Label

up vote 0 down vote Speed: The first part is the type of memory. So, this parameter limits when the memory can start reading (or writing) a different row. It is important to note that this is not the real clock speed of the memory. Birdman1951 replied Mar 17, 2017 at 5:28 PM Window capability?

It tells me the ratio of the FSB to the DRAM clock is 3:2 when I would have expected it to be 1:1 (I fixed this later - see under "Look Ddr3 Ram Specifications Short URL to this thread: https://techguy.org/810675 Log in with Facebook Log in with Twitter Log in with Google Your name or email address: Do you already have an account? This is expected to be the mainstream memory technology to the end of 2007.

Just as a bus in real life is a means of transporting large numbers of people from one location to another, so a bus in a computer is a means of

Naturally they will usually only suggest their own brand name memory as an upgrade. Before you buy a completely new one, however, you should consider ways to... Modern operating systems, and their hardware, require quite a bit more to properly operate. How To Check Ram Specifications So coming back to the real world and our examples from Newegg can you guess what the quoted "timing" numbers are?

As time goes on and visuals get ever better, the amount of RAM required to play the games will keep increasing. Comments: Please enable JavaScript to view the comments powered by Disqus. I'll try to offer a simple explanation, but if all this terminology really makes your eyes glaze over then just remember if all else is equal then the lower the numbers Active to Precharge Delay (tRAS): After an Active command is issued, another Precharge command cannot be issued until tRAS has elapsed.

If you downloaded this from the address in the "Required Tools" section you will have a zip file somewhere in your computer. Are you looking for the solution to your computer problem? flavallee replied Mar 17, 2017 at 5:06 PM Loading... The manufacturer, besides guaranteeing that your memory module will achieve the labeled clock rate, also guarantees that you will be able to keep the labeled timings up to the labeled clock.

Figure 5: RAS to CAS Delay (tRCD) As you can see, RAS to CAS Delay is also the number of clock cycles taken between the “Active” command and a “read” or If you are lucky the RAM stick(s) will have a label giving you appropriate information about the size, speed, manufacturer and possibly some warranty information.
