Why are the Gainward 580s only 2010 MHz memory clock?

post #1 of 5
Thread Starter 
Ive been looking to get a 2nd 580 GTX, virtually EVERY card ive looked at shows Memory Clock:4100MHz or thereabouts but the Gainward ones all show Memory Clockspeed : 2010 Mhz. Is there any reason for this? Or am i missing something.

Thanks in advance.

It's because DDR stands for Double Data Rate. Time the Gainward by 2 and you will find that it is the same as everyone else.

Probably actual vs effective.

You multiple by two like your Double Data Rate (DDR) RAM.

This ^. Companies aren't actually claiming proper speeds anymore and are basically telling you what speed standard ram modules would have to operate at to be comparable. Effective rate is the term they're using and it's almost false advertising DDR can simply be triggered to perform two operations per clock cycle because it's triggered on both the rising and falling edge of the waveform.
