SLI 970 Shutdown

[Bill Lipsit]

I have a new system
Maximus Hero VII board
4790 K Liquid cooled H100I
16 GIG Kingston Blackfury Ram
Samsung SSD plus 2 other drives
2 SLI Asus 970 Video cards
Corsair RM 1000 Power supply

When I run in SLI soon as game starts or quickly after system shuts down.
SLI is recognized in Nvidea

I have moved video cards around in slots, both work fine when running one.
I have upgraded from a 750 Watt to 1000 watt power supply
I have checked all connections
I have checked ram it is good
Have ran furmark test on both cards
Have ran test on CPU
Nothing is overheating at shutdown
I have bought new SLI bridge
Did Bios update

Is there a setting in BIOs i may need to change. I think it may be power problem but do not know
Everything runs great on one card.
Thanks Bill

Is this ALL games?

Did you try updating or rolling back drivers?

Try you old power supply, the new one could be faulty. 750w should run them 970's easy.

Just put a new 1000 watt corsair in because i thought it may be power. i have re-intsalled drivers several times. Only games that run second card shut it down.
Thanks Bill

2 970's and an Intel CPU at stock could be run on a 500W PSU so it wasn't a lack of power. But seeing as how the problem goes through both PSUs it surely is not a power issue unless you have the bad luck of two bad PSUs, but, I doubt it.

You do have all the power plugs in both cards, correct?
You installed the Intel chipset drivers and the management engine?
Are any of your SSDs/drives using a SATA controller that takes up PCIe lanes?
Have you tried these two cards in a different system by chance?

At this point I am wondering if it is the motherboard...

I have checked, been working on for a couple weeks. I have bought all parts at Canada Computers so I will probably take to them to have serviced
Thanks Bill

I have exactly the same setup as you, the brands are different for memory and gpu. I have a similar problem. When sli is on on some games is fine. On battlefield hardline is not. Have you found the issue?
