Hi every one, i got around 20% power consumption increase in v8 compare to v7 and it leads to higher fan speed and hbm temp...
Is it normal?!
I got power consumption increased by 13% using Vega56. Maybe you can tweak a little overclock/undervolt
Maybe this will be useful to someone else: I used DDU to uninstall the blockchain drivers. I updated ONT to 0.2.6. I restarted and applied the current AMD Radeon drivers 18.5.2, release date 5/29/2018 according to driver details. I created the normal exceptions for virus / anti-malware programs for the new version of Cast. I restarted. I applied AMDpixelpathcer 1.4.6, hit OKAY and applied those changes and restarted. I then installed my same old PowerPlay mods. Restarted. In ONT, I went with a conservative P7 state of 1386 / P2 1050 for all 7 cards. That's the setting that I use for weaker cards, but I wanted to get everything running first.
First couple times, Cast would not launch correctly. So I went into the Cast 1.5 folder and copied the Run command line and pasted that into my older start file (changing -u value back to my address). The part at the end was a little different from what I had.
After doing that, Cast started right up. All 7 Vega 56 (bios flashed to 64) are running fine. Only 1 error after 40 minutes of up time so far. Hash rates are in the neighborhood of 1,770 with an occasional spike to 1,800 per card. I set intensity to -7 in the start file. I'll play around with ONT settings later on, I would expect to get a few cards up to 1,800 without much effort. I did not do the usual step of using Regedit to turn off cross-fire (change the value to "0") that I always had to do with the Blockchain drivers.
I do have an integrated Intel graphics driver installed (i7 chip) and I did not uninstall that.
I have not updated the Windows OS in some time. Probably still on last Fall's Creator Update, maybe a version of two beyond that, but I am using a utility to block other Windows updates.
I have not measured power consumption yet, this was more about seeing if I could get everything to work first.
Maybe lucky or something, but really not a hassle at all for Reference Vega 56s and one Sapphire Pulse Vega 56. The Pulse Vega hits 1,800 more frequently than the reference cards.
Edit: 6 hours later, no crashes, no drama
