News Kingston leaks Clarksdale demo ran DDR3 at 1.35V

Oops! Kingston leaks that a recent demo at IDF ran the Clarksdale CPU with DDR3 at just 1.35V to achieve its low wattage.

 

Unless I'm missing something, they're probably just using the Elpida 40nm 2Gb chips that were just announced, that use 1.2/1.35v. Sampling in Nov, Mass production at end of year.

They say they have 100% yield at 1600mhz/1.35v, and I've assuming 1.2v is 1333, so yeah, I'm guessing it will overclock well...

If that scaling is a worst-case scenario (since they can get 100% yield with it), that would mean 4GB sticks doing 2133 at 1.65v...As a BASELINE. When chose chips get binned, expect some amazing speeds.

Granted, I don't know the sticks they used in that Clarksdale machine, but really, we're talking what...<2W difference at load for 1gb 1066/1333 at 1.35v compared to 1.5v. They simply used it so the system would consume less than 70W. IIRC it was like 69.6W or something.

 

Yea, we're just saying that it was confirmed that Clarksdale's memory controller supports it. And on the desktop, not just mobile.

 

This is news I like hearing.

 

Drool 1.2v 1333MHz - I like the sound of that!

 

leaked accidentally , ofcourse
