Max Memory Voltage for Radeon 7950

post #1 of 6
Thread Starter 
I've been searching for information on this but haven't found much, so I thought maybe you all knew something about this. I have a MSI TwinFrozr and a Gigabyte Windforce 3x Radeon 7950 both of which allow adjustment of the memory voltage. So does anyone know what the max safe voltage is for the 7950? What are the negatives of running more voltage to the memory? And does increasing the memory voltage allow for higher clocks than the stock memory voltage of 1.6 or is there no point to increasing the voltage? Thought I'd get some info before I tried pushing the memory any further - don't want to damage the cards. Currently the MSI TwinFrozr is stable at 1280 core / 1650 mem and the Gigabyte Windforce 3x is stable at 1220 core / 1700 mem. Would like to try to hit 1750Ghz for an effective rate of 7000Gbps if that is possible.

I also have a gigabyte 7950 and run at 1250/1900 and I've never touched the memory voltage.

I haven't ever touched the memory voltage. This will be interesting. My stock memory voltage is 1.6 and it can go up to 1.7 but I've never tried it. Just regarding that psyside has said, your chip has a stated "max" of 6.0gbps @ 1.6v. But it all comes down to the temperature/cooling. Every silicon is different.
