I was having wildly fluctuating hashrates for a couple of weeks on both my R VII's, until I realized I need to add some external cooling on my open air rig. Outside ambient temps were about 70-90 F (20-30 C), so apparently just ambient air isn't enough to cool them down. I have two cards, Asrock Radeon VII's with Samsung memory. Before cooling it was running at 79-89 MH/s on Ethereum and fan speeds set to auto, running around 75%. With the speed fluctuations I suspect throttling due to heat.
I went ahead and added a box fan. Result is one card running stable at 89.6 MH/s and the other stable at 89.4 MH/s.
MSI Afterburner settings: Core 950 mV, Power limit -10%, Core Clock 1750 MHz, Mem 1100 MHz, Fan Speed auto.

Does anybody have issues maintaining hashrates on Ethereum?
I just got a new MSI Radeon VII (Samsung memory) and it's unable to hold hashrates, even at stock, no matter what driver or miner I use. This contrasts greatly with my Sapphire card (Hynix memory), which is going at 93MH/s VERY stably. On both cards, I've swapped the cooler for AIO watercooling blocks, which has kept junction temps around 60 degrees C.
On the MSI, I've got the following settings: 1750MHz core, 962mV; memory at 1050Mhz.
It runs at ~90MHs for about 5-10 minutes, before violently dropping down to 47MHs.
I've noticed that when it drops down to 47MHs and I close Claymore, the core clock is stuck at 1750MHz, even though nothing graphically intensive is running.
I've tried cleaning and reinstalling drivers and swapping between PCI-E slots, and the damn MSI just keeps dropping.
Has anybody experienced this, and does this sound like a dud card?

Something similar happens with my card (AMD/ATI with Hynix) but only when the voltage is too low (e.g. at 950mv with around 1780 core clock) and the hashrate actually drops all the way to zero (while the card seems to still be under full load). Lowering core clock or increasing voltage solves it for me. Another thing to try is Phoenix Miner.
See if you need to disable UPLS and crossfire.
Do a search for EnableULPS and registry and see if it applies to your card

Core voltage at 950mv and core clock at 1750mhz has been quite stable for me, with 90+ MH on ETH and 2900 KH on XMR. The junction temperature never exceeds 86 (stock cooling).
April 22, 2019, 11:13:29 AM
I just moved the rig from the top shelf to floor and hashrate went back to 89. Junction temperature is still very high over 100. What are others doing about it?
Do you undervolt your card ? Less voltage means less heat, better speed and stability.

I am trying minerstat with claymore. It starts with 89mhs but goes to 78 after few mins.
Any suggestions how to keep 89?

reduce voltage and core frequency. Stock clocks/voltage vii will throttle

Had someone tested on Nimiq?
Im getting 540khs/card - what about your results and setting?

what oc and watt draw? I'll add to OP
I'm now using your OC setting from that table.
Rig with 2 VII asks for 600w from the wall.

since when did Micron make HBM2?
bear market :shrug:
Radeon VII was never supported in that version of gpu-z. That seems incorrect info.
VII was first supported in v2.17.0 (February 27th, 2019)
you my friend .. are right! thanks for spotting that

I've seen a couple small discounts for the first time this week ($20 or so lower). I wonder if they will go much lower considering the manufacturer costs.
where? https://www.nowinstock.net/computers/videocards/amd/radeonvii/ shows MSRP or higher
It was on newegg, currently they are in stock at MSRP of $700, last week there was a sale at $680. I would be quite tempted to get one if they dropped down to $600 personally but that would be for personal gaming use and hobby tinkering mainly.
