Windows 10: Vega 56 settings and help

Hi , i just installed my new gigabyte vega 56 oc card.
i am running cpu i7- 7700 , pb 500w psu , 16 gig ram ,
I had a go at increasing the power limit , and then undervolting .
I ran some tests with fur mark and time spy etc and sometimes it crashed.
I also got what i think was thermal throttling , but i think it might be my cpu , as even if i set gpu to turbo not custom , it locks up before my gpu fans kick in.
So have i got enough power to run this card?
And if not if i undervolt will it help?
Also there are so many preset setting im confussed as to which to use .
There is in amd settings ,powersave ,balanced,turbo etc, and then within custom there is auto overclock, auto undervolt etc.
First of all i need to work out if my system will run this card on custom, and if it will what custom settings do i use ? , and if not what auto setttings do i choose?
thanks mark

Also i just ran a benchmark on shadow of the tombraider on my 1440 monitor and got 61fps on highest settings, but on world of warcraft it crashes.
Update , after running that benchmark my pc froze , *Sad

Overclocking / Undervolting guide for Vega 56 or 64?

Here's a quick laundry list:

List of software to use for overclocking and testing
Examples:
Wattman (and how to find and use it, like an overview, including profiles)
Unigine Valley or Heaven (use this for quick testing while changing settings in Wattman and checking for stability / artifacts) ...just suggesting this
How to monitor cores / mem speeds and temps during testing (I've seen screen overlays, and others using GPUz)

AMD Asks Reviewers to Prioritize Vega 56 over Vega 64

It seems that AMD's RX Vega lineup won't be too far away from the norm, it seems. Street knowledge almost always says that it's the runner-up to the highest performing graphics card that is the more interesting in a price-performance ratio, and it seems that AMD knows this as well. Steve Burke from Gamer's Nexus has reported on AMD's NDA dates and the company's indications to reviewers on changing up the game leading up to reviews: they're asking that publications focus on the Vega 56 ahead of the halo Vega 64.

This might be somewhat bad news for those who wanted to see the Vega 64 compete in favorable terms with the GTX 1080; this decision by AMD is obviously geared towards making the best impact on the company's product line and image. The fact that AMD can offer a more compelling argument over the Vega 64 means that Vega 56 will probably have an easier battle in the $400 camp (if you can find it at those prices on launch, that is.)







Gamer's Nexus have offered a schedule of sorts for AMD's Vega NDA dates, which are:

• Unboxing embargo lift on Saturday, August 12, 11AM EDT: AMD permits unboxing photos or videos only.
• Performance embargo lift for Vega 56 on August 14, 9AM EDT.
• RX Vega 64 already in hands of some reviewers, with unboxing embargo lift on Saturday, August 12, 11AM EDT.
• RX Vega 64 performance embargo lift on August 14, 9AM EDT.
• Update: Vega 56 launches on 8/28.
