Pour info, Nvidia a reconnu et corrigé ce problème via une mise à jour du bios, diffusée à tous les partenaires.
Donc je vous conseille de faire la mise à jour de votre carte au lieu de bidouiller le voltage.
J'ai testé moi même sur ma carte Palit Super Jetstrem 1070 et effectivement ça corrige bien le problème de la mémoire Micron.
Pour les anglophones, j'ai laissé mon feedback sur le forum Geforce suite à cette mise à jour à lire ci-dessous (j'ai la flemme de traduire...) :

I am happy to announce that Nvidia's bios adjustments have finally fix my Micron memory issue!
No more crash with checkerboard and reboot
Now I can fully enjoy my card with the default optimized power mode, which lower voltage during idle as it should be. No more tricks in order to keep high voltage all the time to avoid memory crash during frequency fluctuations (but drawing more power and higher temperatures on desktop).
Now my card with Micron memory behaves normally, I presume the same way as Samsung memory does (and all my previous GPUs before).
Regarding performance, I get better results on Time Spy with this 3 benchmarks:
1) stock
2) middle OC
3) max OC
All overclocking passed without crash or visual artifacts.
Here are the results.
Default stock settings: core 2012 and memory 4007

After 3 months of struggling with this Micron memory, now my card Palit Super JetStream 1070 behaves perfectly fine, as it should be since the first day (better late than never).
Thank you to brm65 for reporting this issue, to ManuelGuzman and the software team for fixing it, and my Palit brand for providing this flawless bios at last!
