    Jesus, I recently bought a MSI 970 4G and this isn't what I needed. I really hope this can be fixed with a firmware/software update.

    Not really.

    Are you not paying attention?

    I can tell English is not your first language, so I'm sorry if we are losing something in translation.

    Usable doesn't just mean you can fill it with information. Usable means that information is USABLE by an application. It's advertised as 4gb of 7GHz 256 bit memory, not 3.5gb of 7GHz 256 bit memory + .5gb of 1/25th bandwidth memory.

    I'm surprised I need to explain this.

    Here is my results. Is there any reason why the last 2 tests fail for me?

    What is even weirder is that your 980M is getting wildly different results to my own...

    If someone find a way to test GTX 970 to see if really had 64 ROPs (rumors say had 52 ROPs) and find this card dont have it ...
    Then nvidia is doomed and sued by many users,not just money back. :D

    I did not. Though now, as I have connected my monitors to the 970 again, i get the 3.5GiB with 512MiB chunk size... strange...

    I have SLI 2x 970G1 and i can say it's same here except driver crash at last few blocks because i'm too lazy to switch to iGPU and do a headless mode. But people claiming that they had same results in headless mode.

    It's CUDA, doesn't work on Radeons. Someone would have to port it.

    yeah it looks like GTX970 isnt 256bit card.This post should by place as sticky so everyone can read it.

    Anyone noticed that it doesn't respond to memory clock. You can set it to 7GHz or 8Ghz it will always produce same result of 155GB/s. On the other hand GPU overclock or under clock is producing higher/lower L2 cache bandwidth. Strange I must say...

    There are 64 ROPs, it just can't utilize them all most of the time since the pixel throughput depends also on the number of SMMs.

    By the way, someone posted a video illustrating the memory issue:

    having the same mobo i can tell you to boot into the bios, go to system agent and make sure you have the primary gpu as "auto" and enable the igpu.

    boot into windows and just switch the cable . .window may need the intel hd 2000 driver though . .

    I posted this. I'm not saying it IS the memory issue that causes this. I said it may or may not have something to do with it.
