If you own a GeForce GTX 1070, you might want to pay attention to this news-item as you could be effected. There have been some problems reported with certain GeForce GTX 1070 cards. After further investigation it became apparant that the issues like flickering and poor memory overclocking results on the memory sub-system are graphics memory related.
GeForce GTX 1070 cards fitted with Samsung memory do not have any issues, however some manufacturers have or switched towards Micron chips, and these are the culprit of the reported issues. Especially during overclocking of the graphics memory problems will appear fast with bad results like checkerboard patterns. Some users also have reported that at default configuration they noticed the occasional odd issue like flickering or experiencing graphical artifacts. Multiple brands are and could be effected. Right now most of them are working on (or already issuing) a BIOS firmware update for the graphics cards, these BIOS updates likely increase the voltage level of the GDDR5 memory. Minf you that this only effects GeForce GTX 1070 graphics cards fitted with Micron based GDDR5 memory.
I've been doing some rounds at the manufacturers with the following info (we'll update as feedback gets in). A number of manufacturers is or have been working on VBIOS updates:
- ASUS: not yet available
- Gigabyte: No Micron memory was used but is double checking with R&D.
- Inno3D: not yet available
- KFA2/Galaxy: not yet available
- MSI: not yet available
- PNY: not yet available
- Zotac: not yet available
