I had purchased these for a Dell Optiplex but when they arrived realized they were the wrong CL.. and they have laying around since. Bought from PC-Parts Express
Clock speed determinds how fast your computer will process information. When it comes to RAM it dictates the minimums processor it is compatable with. EX. 133MHz ram will work in a processor with a clock speed of 500MHz, But a Ram clip that is 500MHZ will not work in a computer with a clock speed of 133MHZ.
About all I know is what is on the sticker. I would google the brand "Infineon" and what I have list, and compare your computer to these RAM sticks for compatability. Sorry I don't have a more definitive answer.
I have two memory slot, If youonly have 120mb my question would be how old is your PC . Most memory sticks run 128 Mb, 256Mb, 512 Mb, 1Gb, 2Gb. Also from my experience with older PC's, if they only have one slot for RAM then the rule is you should oonly double the amount. *NOTE* Check your PC's system information folder. There it should tell you what RAM (Vertual memory) and what usable memory you have it sometimes will also tell you the capacity of Ram you may install. I hope this helped.
ya i was going to say, i havent even heard of 120 mb memory sticks.. i have 2 512s in my computer with Vista. i upgraded from an old hp pavilion xp os so i added more memory and a bigger ata drive.
the 120mb is not due to the size of the ram, its due to him having onboard video that is reserving 8mb of ram. Therefore he has a 128mb stick of ram with his onboard video taking 8mb of it, leaving 120mb for the computer to use.
Thank you, It is very nice of you to add helping information. I greatly apprieciated it. I hope this will answer other bidding questions for others. Thanks again for your expertises..
the ram listed is ddr pc2100 which is 266mhz speed, (133mhz X 2) ddr stands for double data rate which means data is transferred at the beginning of the cycle as well as the end of it, giving the effect of double data rate, hence the 133 X 2 = 266mhz. DDR is sdram or Synchronous dynamic random access memory ...DDR is just double data rate synchronous dynamic random access memory.
"133MHz ram will work in a processor with a clock speed of 500MHz, But a Ram clip that is 500MHZ will not work in a computer with a clock speed of 133MHZ."
This is actually not true...modern day Ram you will use will clock itself down to a slower bus speed, called under-clocking...this was not true in the days of non-parity and parity ram, but most people will not see this type of ram in a computer within the last 15 years...
