Have you used GPU-Z or similar software to check the memory manufacturer on your cards? (Samsung, Micron/Elpida, Hynix, etc.)

Samsung memory usually overclocks better, but it does vary unit-by-unit.

Additionally, what software are you using to change your clock settings?

Using MSI Afterburner to change settings.  Also tried just the nvidia-settings under Linux as well.

1060 - Micron
1060 - Samsung
1070 - Micron
1070 - Micron
1080 - Micron
1080 - Micron

I've tried to up the TDP to over 100% (power usage not an issue for me) and that didn't make a difference.

Stats (no overclocking):

Code:
GeForce GTX 1060 6GB   104.07 W   85 %   76         1620 MHz    3802 MHz
GeForce GTX 1060 6GB   113.01 W   85 %   77         1670 MHz    3802 MHz
GeForce GTX 1070       157.30 W   70 %   64         1657 MHz    3802 MHz
GeForce GTX 1070       162.28 W   70 %   70         1657 MHz    3802 MHz
GeForce GTX 1080       161.54 W   70 %   59         1708 MHz    4513 MHz
GeForce GTX 1080       171.54 W   70 %   67         1708 MHz    4513 MHz

I have one rig with 2 x ASUS 1080 FTW (non-Ti), 2 x Zotac Mini 1070 and 2 x Asus 1060 3GB.  I've also got 2 x EVGA GOLD 750w power supplies, making sure to put 3 cards on each power supply.  Eacy powr supply shows about 550w used peak.

If I try to overclock ANY of them, the rig will crash.  I can overclock the 1070s memory by about 200MHz, but they will crash about an hour later.

In the logs I can see that it's always either one of my 1080 (PCI:5) or a 1060 (PCI:1) that crashes.  I've tried just overclocking the other cards and leaving those as stock, but the system still reports one of those crashes.  I've tried just increment the overclock by very low amounts, but with any amount of overclock, the system becomes unstable and won't stay up a day without crashing.

The system is solid and with default clocks and doesn't crash though.

Any ideas?
