The reason why the GTX 1070 is not working with the amplifier when hooked up to an alienware laptop is because the drivers installed on the laptop do not support the GTX 1070 Desktop GPU, you just have to wait for NVIDIA to release a new update which adds support for both GTX 1070 and GTX 1080....
The core clock is dynamic. Mine appears to be working fine. NVIDIA 1080 FE. A laptop system is generally going to bench lower than a desktop - I'm not worried about benchmarks as much as how my games actually run.
Right now the drivers support the 1080. The 1070 can work if you leave it in the AGA and install the desktop drivers, but it can get a little funky when you disconnect it.
You also have two threads saying basically the same thing, but don't seem to be coming back and participating in the replies.
As I just mentioned on your other one, you did plug in the full 8 pin power plug to the card, and you have removed/reseated it, making sure the PCIe latch is fully engaged, correct?
