I am trying to be able to tell by looking, the difference between AGP slot DDR and SDRAM video cards
from what I have seen though, I am confused
to my knowledge since my SDRAM Geforce 2 is a "two tongue" AGP and my lady's DDR radeon AGP card is three tongued and the cards won't even fit from one computer to the other...I assumed that was the easiest way to varify the difference at least in AGP
then looking online I see where some folks have cards for sale and are saying they are SDRAM but they have three tongues
Peter M...Sorry if it so hard to 'read'...don't forget to be polite here please...
simply put....
I am trying to see if AGP video cards can be distinguished between DDR and SDRAM by eyesight alone
look on ebay and you will see numerous cards that have no listing of what type of memory they are
you look at some SDRAM cards..well of the pics there...you will see some labeled SDRAM that have three "tongues" ...
three AGP SDRAM cards I have here at the house are with two tongue application....now I am not to smart but two tongues won't fit in a three tongue slot
on my girlfriends DDR video card...its a three tongue application...while all new DDR video cards I see online are three tongues too
with due respect...that should be simple to understand
and BTW...thanks Bipolar...thats an easy way to find out about the type ram if I have it in a system board true
First, the video card's memory type has nothing to do with the AGP interface (the tongues as you call it). Rather than thinking of it as a series of tongues, think of it as a single connector with one or more notches cut into it.
Older cards, based around the AGP 1.0 spec had a single notch that matched a key in the slot connector on the motherboard. The next generation used the AGP 2.0 spec and introduced a second key in the slot.
Now it happens that older cards were more likely to have SDRAM where the newer ones have transitioned to DDR. What happened is you are seeing two separate transitions, of AGP revision and memory types and trying to find a connection that isn't there. Yes there is a general correlation, but it's purely circumstantial and based on two independent factors that have nothing to do with each other.

Hey, I wasn't being unfriendly, just brief. You'll notice when I'm getting unfriendly
Exactly. The AGP connector tells you what AGP signalling voltages the card is capable of. The key tabs in the slots and the key notches in the connector blade prevent you from plugging electrically incompatible stuff together.
This is nothing at all to do with what the card itself is doing on its own circuitry. This of course includes the kind and speed of RAM it uses.
