Regarding the freezing rigs after connection loss or after a gpu hang:
First of all, some of you may want to take a look at my previous posts, I have been trying to keep everything summed up for people with similar issues to be able to check them out all at once.
So here is my initial post and here, here and here are the ones that followed on that issue. For those of you guys that just want to read my conclusion, you can skip those.
My "verdict" is that sometimes when the miner starts it causes a power consumption spike, which may be above your rig's max power. For me it happened almost always after a connection loss and sometimes after a gpu hang.
First of all, here is a graph of my power consumption during my tests:
Keep in mind that I have 2x 750watt gold PSUs, so 1500 watts is my limit. Now take a look on those spikes.... yeah...
I will spare you from too much of big data and focus on the incident I have my cursor on in the above image (04:32 2017-09-17)
Here is a log from that connection loss:

Since the above graph is too zoomed out, here you can see a zoomed in cut from that incident where you can see that after that spike, my rig froze:
The other spikes you see on the main graph on top are the same case (those 1800+watts made me skip a heart beat when I saw them).
So, in the end of the graph you see stability. This is the most continuous period I have managed to run my rig for with the blockchain drivers. The fun part is how I did it:
I changed:
-cvddc 875
-cvddc 850
Such a lame ending for such a big torture I have been through... I changed that in order to reduce my power consumption so my spikes would be withing my PSUs capabilities, and while I did that, no more spikes!
So that was it. I have been running stable since then, I sacrificed 10Mhz of my -cclock in order to keep up with the 25mV reduction on -cvddc so I lost a bit of speed, but at last I don't have to wake up every 2 hours or so to check on my baby-rig.....
Conclusion:
My "verdict" is that sometimes when the miner starts it causes a power consumption spike, which may be above your rig's max power. For me it happened almost always after a connection loss and sometimes after a gpu hang.
If you experience rig freezes with blockchain drivers and Claymore v.10.0, the miner could be causing spikes that are beyond your PSUs capabilities
P.S.1: In the graph you can see that in the middle of my "stable period" the power consumption got up a bit. This is because I initially dropped my -cvddc to 840 before I decide to step it up to 850.
P.S.2: The freeze issue was happening on the following equipment:
ASUZ Prime Z270-P
8x RX 580 8GB Nitro+ (Hynix)
Windows 10
Blockchain Beta Official Drivers
Claymore Dual Miner v.10.0
Modded BIOS, OC through Claymore @162w from the wall per card
Dual mining ETH (233 Mh/s) +DCR (7000 Mh/s)
-esm 0 -estale 0 -asm 1 -dcri 30 -cclock 1140 -cvddc 875 -mclock 2100 -mvddc 850 -tstop 80 -tt 70 -fanmin 15 -fanmax 85 -mode 0 (These are my parameters before I applied the solution I describe above. Also, -mclock 2100 was +/-30 for some of my gpus)
P.S.3. Sorry for the long post... Keep in mind that it was a hell of a lot longer for me
