@Feld try undervolting to around .990V and rerunning some benches. When I do that to mine, the fan never goes above 2200 2500 rpm with the default profile. Temps stay nice and low. I was able to complete Superposition 1080p extreme and 4k optimized without any hiccups using my undervolt profile. Haven't tried it with the 1940MHz overclock profile yet.

Also, does the power slider do anything for you in Wattman? For me, it does nothing.

And could you try running GPUPI and AIDA64 GPGPU bench? Tell me if your memory speeds drop to 800 MHz on any memory overclock. If you leave memory speed at stock, it should stay at 1000 MHz, but if you overclock, it drops to 800 no matter what.

Got mine, likely won't have time to install/test until the weekend, though.

To see if the power slider does anything you need to be monitoring how much power your machine is consuming. That slider lets AMD cards draw less, or more current. Setting it up will allow you to overclock a bit more in some cases. Setting it down will help the card to use less power, but at a possible hit to performance. But the effects are typically minor.

Sure, I'll try those things out tonight after work. Regarding the power slider, I only used it while mining so far but yes, turning it down does reduce how high of a clock speed the GPU runs at and of course reduces power consumption. I haven't tried turning it up since I was already unhappy with the fan noise as it is.

Yes, I tried moving mine around, and my Kill-a-Watt registered no change, even at -20% power limit. I also got no clockspeed change, even in intense benchmarking.

Odd. I'll play with mine more later after another driver release. I find it interesting that AMD has thus far restricted the slider to +/- 20%.

Just tried the washer mod with the same size washers that TechPowerUp used (Nylon - M3x6mmx0.5mm). Noticed when taking the bracket off that not all screws were tightened to the same amount of torque. I wrote down how many full turns it took me to undo each screw so I could put it back together the way it came. I used a #00 Philips Head Screwdriver and three out of the four screws took 5.5 turns to undo. The fourth took six. I understand that these are mostly hand made so it's expected, just an interesting observation.

Anyways, the washer mod has had no effect for me despite torquing down each screw to it's original tightness. I even tried tightening each screw up a little more until it was a comfortable hand tightness. Just kind of did it by feel. Disappointing, but worth a shot. Junction temperatures always seem to be 25-30°C higher than core temperatures when running 1825 MHz @ 972mV with a custom fan curve (tops out at 52%). Temperatures aren't bad (64°C/91°C) but I wish they were better so I could push this card further. Not sure if I didn't tighten enough or did something wrong, but it looks like I'll have to sack up and lap my cooler like another user did over at OCN.

Alright, I tried 990 mV but my card is not stable that low. It hard reboots randomly even when underclocked to 1675. I seem to need a minimum of 1013 mV for stable operation. And looking at what others are reporting, my stock voltage of 1138 mV is much higher than the average people are reporting here: https://docs.google.com/spreadsheets/d/1Iim9e_ejX3nkgxLIZ3vLu1seQ1m0lDTKUhClJpAO-Gk/edit#gid=0 It looks like I got a bit of a dud as far as undervolting ability.

I tried out GPUPI and AIDA64 GPGPU using all stock settings and didn't see any funky behavior. The HBM clock stayed pegged at 1000 the whole time.

1013V isn't that bad. Also your stock vGPU is the same as mine.

Try overclocking your RAM to 1001 MHz and see what happens to the RAM speed then. It should drop to 800 MHz.

Received an Asrock Radeon VII yesterday from Newegg (storm here in the East coast delayed delivery a day). Paid $699 plus tax so @$750.

The card came in an AMD box with nothing but the card and a small pamphlet.

Very solidly built.

Took a bit for my 2700x/GTX1080 rig to recognize it but finally got it running.

Removed all of the Nvidia software AND updated the Radeon BIOS via the download from Asrock

Then installed the AMD new Adrenaline drivers. I'm still learning where all of the adjustments are.

Fast video card.

Once I have time to play with it I'll report more of my findings.

Sounds good. Enjoy the undervolting.

Something I've noticed has a tendency to cause crashes is turning the monitor off. It's regarding that idiotic bug (that Microsoft pretends is a feature) with Windows where if you physically turn off a monitor that's connected by displayport, it thinks the screen has been disconnected and resizes all your open windows as though it has to fit them all on a 1024x768 display. I hate that, so my workaround is when I leave home or go to bed I go into the Windows Power & Sleep settings and set it to turn off the display after 1 minute of inactivity, because that way Windows actually realizes that the monitor is still there and doesn't move and resize anything. Only now it seems that the GPU doesn't like that and has a tendency (though it doesn't happen every time) to cause a hard reboot either when Windows turns off the display or turns it back on once I come back and move the mouse. Hopefully this gets fixed in the next driver update - seems like it should be some low hanging fruit.

 

[DrMrLordX]

@Feld that's really odd. Good catch though.

 

[ozzy702]

Mining performance? Anyone mining undervolted? What kind power power draw from the wall? How about temps? I know it can pull 90mhs on ethash, what about other algos? Hopefully some sweet bios are released for it. I'm pretty tempted to pick one up. Power isn't a concern for me, but thermals sure are.

 

[DrMrLordX]

@ozzy702 thermals become less of an issue if you undervolt. Also you can try running down power usage some - initially my power slider didn't do anything, but now I can get -20% power usage to lower the score in some of my benchmarks, so obviously it's doing something.

I haven't tried mining on mine at all. The only software I have on my system right now is an old revision of Claymore's Ethereum miner. If there's something you want me to benchmark, let me know. I'll see what I can do.

Yes, I haven't mined any other algos but right now I'm mining Ethereum underclocked at 1675 MHz and have now gotten it to do that stably at 953 mV, and with the memory at 1050 (it goes much higher, but doing so doesn't help the hashrate at that core clock). With those settings I'm getting ~86 MH/s and the card itself is pulling close to 250 W from the wall. I haven't really tried hard to maximize efficiency yet though, just cut the power limit to -20% and dropped the voltage. I forget where, but I saw somebody had gotten their card to do 78 MH for under 200 W.

 

[guskline]

Thank you Feld. Though I don't mine, it's good to know this type of info on a new release.

Just ran the Passmark scores for my 2700x/Radeon VII combo and compared it to the 5960x (OCd to 4.4)/GTX1080TI Ocd and WC.
I'll post the 2D Mark and 3D Mark scores for each video card so you can compare.
For the Radeon VII

2D Mark 964
Simple Vectors 37
Fonts and Text 300
Image Filters 1258
Direct 2D 51
Complex Vectors 133
Windows Interface 121
Image Rendering 1003

3D Mark 16383
DirectX 9 220
DirectX 11 296
GPU Compute 8382
DirectX 10 322
DirectX 12 93

For the GTX1080TI OCd

2D Mark 948
Simple Vectors 40
Fonts and Text 296
Image Filters 1152
Direct 2D 84
Complex Vectors 144
Windows Interface 84
Image Rendering 1389

3D Mark 17131
DirectX 9 234
DirectX 11 368
GPU Compute 10729
DirectX 10 371
DirectX 12 81

I have a licensed version of Passmark so these are the respective scores.

Since the 5960x combo is custom watercooled I didn't want to tear it down and move it to the 2700x rig to use the same cpu platform but the cpus are close enough that some comparison will help.

I've noticed Radeon VII is getting (even more) scarce, and Newegg appears to be de-listing SKUs as they sell out.

I wonder if there will be more or it was really that limited a production run?

 

[n0x1ous]

Anyone else flash the new V106 bios?

Amazon actually had some pre-orders earlier this month that are all supposed to ship by March 1st. So I would expect another wave of cards by then. Maybe.

Not yet! I heard from some folks that they can undervolt more now but that the GPU apparently downclocks itself more aggressively due to undervolts with the new BIOS. I can't confirm it but I'm not eagre to test it myself.

I flashed last night but haven't gotten to test anything yet. Theres a beta of gpuz on the techowerup forums with RVII support now and its showing the updated bios and UEFI support now

EDIT: also new beta of afterburner available with RVII support

Which brand of card did you get??

Looks like XFX.

That’s the unbranded version from AMD.com
