Nobody besides NV should look into driver related issues. Neither me in AB, nor w1zzard in GPU-Z, ASUS in GPU tweak, Gigabyte in OC Guru or EVGA in Precision (and each of tools is reported to be affected) use anything but NVIDIA's own official NVAPI to display graphics card state in realtime. And NVAPI is build special to provide graphics card state reporting to vendor specific software.
The only thing you achieve by increasing polling rate in AB and similar tools from 1000ms to 6000ms is reducing the amount of access to NVIDIA driver via NVAPI with 6x factor. The amount of NVAPI calls during 10 minutes of testing with 1000ms polling period is equal to 1 hour of testing with 6000ms polling. If there is a problem randomly occurring in driver once per let's say 10000 NVAPI calls and you needed roughly 3 hours to reproduce it with 1000ms polling rate, then you'll need roughly 18 hours with 6000ms period to have comparable chances to reproduce it. It is not a fix by any means, it is a placebo that makes the problem harder to reproduce. If those who follow the guide of "fixing" it via altering polling rate don't get it - that's not my problem.
