Updating memory problems
As a result of these issues, a VBIOS update is being pushed out by a number of manufacturers.
Some of the GTX 1070 models equipped with Micron memory have been known to suffer from odd issues like flickering before any overclocking is even attempted.
Recently, add-in board partners began using Micron as another source of memory chips for the GTX 1070, which has resulted in flickering and poor memory overclocking results on some cards.
GTX 1070 models running Samsung memory do not appear to be affected.
If you own a GTX 1070 and want to check whether you have Samsung or Micron memory, you can do so using GPU-Z, which will tell you which memory type you have.
Apparently, Gigabyte did not opt to switch to Micron memory during manufacturing, so Gigabyte GTX 1070s should be fine, though the company is said to be double checking with its R&D department to make sure.
