Vega 56 stock voltage
The Radeon RX Vega 56 is the weakest member of AMD's Vega GPU family. The Vega architecture is built on 14 nm silicon and contains next-generation compute units (nCUs). Each NCU houses 64 steam processors, of which the Vega 56 has 3584 vs. 4096 in the Vega 64. The new architecture employs 8GB of second generation high-bandwidth memory (HBM2). Vega 56 Pulse because Vega is power limited by default at 1.2v. undervolting allows less power usage rendering a PL 50% useless. I've had about 5-6 Vega cards. One was a serious dud and couldn't When undervolting my Sapphire Pulse Vega 56 by just 1mV, SCLK immediately drops down to 700 Mhz and pstate 1-2 under load (`gputest /test=fur /width=1920 /height=1080`).

The Vega 56 GPU is already a very capable basis for a graphics card, and the performance is up there with the GTX 1070 Ti, not an inconsiderable card itself. With the addition of the Strix trimmings - DirectCU cooler, RGB lighting, AURA Sync connector and fan headers - it already steps up into something that would require serious consideration.
With a custom cooler system the Vega 56 can be really cold and On stock reference Vega 64, drop mV to 900 for all voltage settings and set
Surprised you are able to get 950mhz on the memory with the stock 56 bios. My card would not go above 900mhz on the stock 56 bios with 1000mv. I tried 1050 and 1100mv and it didn’t help me pass the 900mhz barrier. Only the Vega64 bios let me pass that barrier (as shown in the settings above).

This is unsurprising in the case of Vega 56, which has lower stock clocks than Vega 64. It's not that only "golden" chips can undervolt. Rather, all but a tiny handful of trash chips can undervolt, and those trash chips should have been discarded instead of allowing them to drag down everything else.

With the addition of the Strix trimmings - DirectCU cooler, RGB lighting, AURA Sync connector and fan headers - it already steps up into something that would require serious consideration. Recieved my new Sapphire Pulse Vega 56 couple days ago, I really seem to have some decent clocks for mega low voltage. Check my screenshot. This is stable at folding and gaming. During folding core runs at ~1609mhz, memory 950mhz and ~960mv. During gaming core clock runs at ~1600mhz and memory 950mhz again at 960mv. Radeon RX Vega 56 (with flashed BIOS and OC): 11322 pts. Given above are the FireStrike Extreme scores of the RX Vega 56 and 64 in their various configurations. This really makes sense, 130W can be handled by a high end Laptop cooling system and apparently the Vega 56 in it is competitive with the Mobile GTX 1070. I actually run my Vega 56 Pulse (We have the same card yay!) at 1500 Mhz and 1.025V (in my "optimised" mode) and my power usage is around 200-230W depending on the game. RX Vega 56 Not Reaching Advertised Boost Clock. I've recently purchased a Sapphire Radeon RX Vega 56 and have noticed that it won't reach the advertised boost clock of 1471 MHz when running either the Balanced or Turbo profiles from within Wattman. The highest clock speed I've seen is 1440 MHz, which while close is still under performing.
2% over stock, and the A Vega 56 comes stock with P3 memory clocked at 800mhz and a Vega 64 Your tuning goal is to find the minimum memory voltage
