|"Bought A Std. 8GB SDram"|
It's not called an SDram card, it's just called an SD card. SDram is a memory module for laptops and desktop computers and is a completely different thing altogether.
The slot on the tablet is for a MicroSD memory card, not a standard SD card.
There is just no way a standard SD card will fit into a MicroSD slot.
if the card is a MicroSD type, make sure you are putting it in the right way up. on most devices you insert it with it's label face up, but on your tablet it may have to be inserted with the label face down.
