Talk:DIMM

From Wikipedia, the free encyclopedia

Hi. Thanks for the explanation. I still don't understand what is "dual" about the dim, nor do I understand what is "in line" about it. Is the DIMM "dual" because it carries information on each side of a pin? I am trying to understand what makes a DIMM, different than a SIMM. Thanks for any help you can provide.the major difference between simm and dimm is that simm can work on single line that is it can work on one side of the ram whereas dimm which is dual in line memory module can work on both sides of the ram. sub:varun verma

hello my name is siby. i whish you include the speed of DIMM used in computer system.

I added an explination of the differences between DIMMs and SIMMs. And I think this article has enough information that we can remove the stub status. Any objections? --Pboyd04 20:42, 26 December 2005 (UTC)

[edit] Pin layout

Does anyone have references for the pin layouts and method of operation of the different types of DIMM? It would certainly be useful to address this topics. JulesH 11:17, 13 October 2006 (UTC)

you 're right. i have inserte the package gorm of 168 pin (13 cm and 2 holes), i'd like to see others version too. --83.190.155.53 17:10, 12 September 2007 (UTC)

ps i was looking for package list and i found this page [1] (sorry this is a commercial site but i haven't found a free site yet) —Preceding unsigned comment added by 83.190.155.53 (talk) 17:16, 12 September 2007 (UTC)

[edit] DDR1 and DDR2 Speed

In the speed section can you clarify the difference between the speeds of DDR1 and DD2... is the strobe at the same speed as the data and twice the clock in both cases? ...

DDR1 ...have data but not the strobe at double the rate of the clock. i.e., PC1600 = 200 MHz data & strobe / 100 MHz clock for address and control .... DDR2 ... also (?) have data and data strobe frequencies at double the rate of the clock. i.e., PC2-3200 = 400 MHz data & strobe / 200 MHz clock for address and control ....

[edit] Memory module description in EEPROM chip

I miss a notice that most DIMM modules carry a small EEPROM chip that describes specification of the module (capacity, timing, manufacturer, etc). And I miss a detail article about this EEPROM chip, that is accesible at I2C bus on most cases as I know. Information from the chip can be read with Z-CPU freeware under Windows, for example. BIOS process the information from EEPROM chip too to configure system to optimal values during computer boot.

Well, I found the article about SPD: Serial_Presence_Detect —Preceding unsigned comment added by 89.24.36.147 (talk) 11:12, 27 January 2008 (UTC)

[edit] MicroDIMM?

Given that there's no definition of exactly what a MicroDIMM is, in what devices it is used, etc., I have a hard time understanding why MicroDIMM redirects here, other than the fact that the word is on the page. Anyone care to add a description? —Preceding unsigned comment added by 67.91.44.34 (talk) 15:53, 6 March 2008 (UTC)
