Does anyone know if thats possible with the 79xx series? (flashing the bios). I understand initially it wasn't, but I have heard rumors of ways of getting it to work.

As of right now, No.

So after all debate about PowerTune, should we use 0%, 10% or 20%?

+20.

It's nice to have an AMD rep here post useful information. Hopefully you will not get flamed too much everytime AMD release some new driver sets.


I gotta ask, AMD's calculated attempts to make MSI afterburner not work properly or difficult to get working, is it because AMD's largest parter Sapphire decided to release trixx?

Your score seems reasonable, but it depends on whether your CPU is overclocked or not. I will put it into perspective for you. My (old) 7950 gave me around P9500 with my 2500K clocked at 4.5Ghz. To get that score, I had the card at 1225Mhz on the core and 1750Mhz on the memory. Graphics score was a touch over 10,000, while my physics (CPU) score came in around 8250. Now that you have those figures to measure up against, you need to see how different your clocks are on both the CPU and the GPU to mine and figure out if there is a problem. I was using the latest drivers also. 12.6 and 12.7 beta seemed to be fairly similar. Hope some of this info helps.

Thanks for the help, what did you use to unlock the core and memory?

I notice that my 3Dmark 11 score decreases as I increase the memory clock past 1350, anyone care to explain?
I have tried adding another 5% to the voltage to get to 1050, but that doesn't work. What would you suggest as a next step?

As far as I know DDR5 has built in error checking. Excuse the non-technical terms , the way I understand it is if an error is detected ( due to overclock) it can be corrected by the error checking but this uses clock cycles and thus the GPU has to wait while this is happening.
A solution may be to use AB to up the memory voltage and core voltage if nessary.

Why do the AMD cards only come with one dual link dvi anyways?

So if a reference 7970 wasn't ever overclocked and suddenly it's running at 66 degrees Celsius in idle spitting out all kinds of crazy artifacts, it means it failed to avoid meltdown?

No, it means it avioded meltdown and only sustained slight damage rather than blowing up your computer, followed by buring your house down. I'd rather than artifacts than no house. thumb.gif
