is there any way to visually tell the difference between between sdram rdram and ddr ram>?
DDR RAM is a type of SDRAM.
RDRAM is totally different.
Depending on the model computer (desktop or laptop) and the type of memory (SDRAM, DDR SDRAM, DDR2 SDRAM, RDRAM) the number of pins is different.
Simply Google the part number printed on the stick to learn what you have in your hand. Or, if it's in a computer, you can go to Crucial and learn what type of memory your computer takes.
Do NOT buy memory for a Dell computer based on appearance or even trying to match specs. You will likely fail.
To follow-up on BigBrother's last reply, to be found in your previous recent thread: What are the results of your examination of the four diagnostic LEDs on your machine? This information may be helpful in trying to help you diagnose your system's problem.
The fact that you get no video on your monitor is related to the fact that your system does not complete POST. The computer will simply stop doing POST tests if one fails. The memory test comes before the video test in the POST sequence. If a POST fails at memory, it will stop at that point. Video will never even be initialized. Under the circumstances, not having any video on your monitor is normal.
yes i followed his instructions and identified this to be a problem with my ram. i tried the ram in both memory modules and i get the same result - 3 beeps and A B light up yellow while C D light up green. I kept repeating myself because i never knew a memory problem to affect video - maybe this is just a symptom of the system failing POST, which is something i'm very unfamiliar with and have never heard of until a few days ago.
this is nothing major - but the white snap-on things that hold the memory modules in place dont exactly snap in tightly due to the height of the ram. but since the samsung ram that i had in there was identified as the ram that came with the system, i guess that isnt an issue, is it?
