file Question Graphics memory overclocking

6 years 3 months ago #501 by Tugrul_512bit
Since this benchmark depends on vram speed, I am asking if 1.65V or 1.7V is dangeros for a 1.5V-default vram?
What if card's default is 1.6V for the 1.5V memory? Does this mean we can change to 1.7 safely?

Hi,

Well it's more a question to AMD engineers :(. Can't help you with that

Hynix VRAM on the 7970's at least are specced at 1600Mhz 1600mV. My Matrix comes stock with VRAM @1650Mhz 1600mV,

There's not a whole lot of headroom for OC(150-200Mhz, and it doesn't help that much, the bandwith seems plenty) Adding more than 50-60mV tends to give me artifacts.

Just keep an eye on the temps and you're fine.
