Sorry for bump in after long time of inactivity of this thread ...
But I almost have the same problem
I setup a new rig and have problem mining with 6 cards, all 6 cards installed and detected by system
When I enable the 6th one after 10-15 minutes of mining cpu usage goes high and reach 90%. no program with high cpu in task manager but "system"
Tried with MSI afterburner running to speed up fans, and without it

All 6 GPU are detected and working fine, tried to run with 5 and cycle the 6th one to check if problem is from risers or power cables ( Disabled pcie1 , run with 5, disabled pcie2 run with 5 .... )
All ok with 5 GPU no matter which one, as soon as I enable 6th the cpu goes high.
system is :
Windows 10, 1703 , all drivers updated to latest with "Driver Booster"
Mobo: MSI Z170A XPower Gaming Titanium Edition
PSU: Thermaltake Toughpower XT Gold 1275W
GPU: 6x 1070 Asus Dual 8OG
Ram: ADATA XPG Z1 DDR4 8GB 2800MHz CL17 Dual Channel
CPU: Pentium G4400 3.3GHz LGA 1151 Skylake CPU
HDD: SAMSUNG 750 EVO 120GB SATAIII Solid State Drive

PEG0, PEG1, PEG2 gen 1 (tried with auto too)
4G enabled
IGD disabled (tried with enable too)

Can any one help me please.

Bumping! Same issue I am facing now with RX570 cards
