Ooh great numbers

Ooh great numbers mesman21..... and I laughed at the “They are $700!” Comment :-D

so true. Selling above the rrp... which is typical these days :-/

some great reading here and thanks for your analysis Gary! 

I hear that there won’t be any aib cards but I’m unsure if that will be the case.

Hey Mesman, what are the temps like? 

Ive read some pretty high readings when the card was released (110 celcius)

FYI, I have a developer friend that has put together a Linux utility for controlling AMD/ATI cards.  It can control clocks, power levels and p-states.  Seeing requests here frequently for the ability to undervolt AMD cards for power usage savings, I thought some might find Rick's utility helpful.

https://github.com/Ricks-Lab/amdgpu-utils

He would like feedback and requests for new features.


Okay, this isn't a Vega VII post, but thanks to your tip Keith, I've been working with Rick on getting his amdgpu-utils to run with RX460 and RX570 cards on my Ubuntu host, and he got it to work great!  I was able to successfully power limit both cards, something I was not able to do, or do stably, with other Linux utilities (see comments in post https://einsteinathome.org/content/suitable-linux-distros-boinc.)

Ideas are not fixed, nor should they be; we live in model-dependent reality.

Right now I'm crunching at a little better than 1.7M /day and pulling about 450W at the wall with a Gold rated 850W PSU. The VII is lightly under-volted with power limit % of -20 (which is the lowest Wattman currently allows on the VII).

Good news everyone! After additional GPU tweaking and side discussions I came to suspect that my power meter was faulty; especially after I noticed that it was reading 152v at the wall! So I bought a new one and it arrived today.

My new meter is reporting only 280W at the wall with the same settings as noted above! It's also measuring 120v, so that's a good sign! Sorry for the inaccurate information previously.

Readings of 110C are possible but not comparable to previous generations because AMD has changed the way the temperatures are reported. There's two readings, the traditional GPU Temp and the new Temp Junction which is a hot spot reading. The Temp Junction readings are usually 20 to 25C higher than the GPU Temp. I run a custom fan curve because I don't like how hot the stock settings are (I do the same with Vega 64). I keep the GPU temp at 70C and the Temp Junction is 90 - 95C. Fans are spinning around 2,000RPM in a well ventilated case.

As with any modern GPU, the temps are really just based on how much power you're letting it consume and the level of fan noise you're willing to withstand. My experience is that the VII performs similarly to a tri-fan Vega 64 in this regard; the difference is that run times are about 40% faster time with similar power limit and fan settings.

The Radeon RX Vega 56 might be a worthwhile low cost (and lower power) alternative:

Apparently that "sale" was a bit bogus and only VERY temporary.
