Also: I have no issues. My card uses all its memory when needed.

 

Curious, do you have Hynix or Samsung memory?

does Zotac 970 cards have Hynix or Samsung memory?

You can check with Nvidia Inspector from guru3d.com

Samsung

 

Allegedly it's supposed to affect Hynix cards more. Who knows though? Maybe someone will put out a more useful benchmark than Nai's. Out of curiosity, do you get the same results everyone else does with Nai's benchmark?

Is the benchmark just a bit buggy or is it meant to be like that?

Yeah that benchmark is inconclusive at best. The 'drop off after 3.5gb' appears to happen on any card when it is run with desktop composition enabled (which can't be disabled in win8). The only results I've see where it showed full speed for the entire test were the people who ran it with the nvidia card in headless mode.

 

This controversy is largely based off of a completely inconclusive benchmark that is being run under a variety of different conditions by random people.

Im curious ... how the 2nd pool vram is still faster (linus said about 20% faster) than the system ram if you can reach more than 28GB\s (according to aida mem bench) with a good oc and a memory kit ?

No matter what system ram the gpu v ram us much faster even if it's not 8000mhz, my question is when we overclocked the memory does it overclocked all the modules?

I would say yes ..

 

btw: the second pool isnt that fast .. i can easily reach more than 28GB\s with my dual channel kit

Yes, there is no difference in the physical vram modules, they are all gddr5 and all run at the same clockspeed.

I hope they sort this because i wanted my GPU 2 be a 970 i hope they sort it!
