Monero hashrate drops when you disconnect your monitor (even if you are on IGP), or the screen power shut down after a while.
Simple disable screen power shut down, and do not disconnect your display while mining.

I tried this but still get hashrate drop. Does the monitor still need to be on as well?

I can't use IGPU as my monitor only has DP input.

I can confirm... my hashrate drop issue still exists. I even have a dummy HDMI dongle and also set power profile to max performance (never turn off monitor). Still no go. Performance drops after 10-12 hours. I even reduced the overclocks, but no success.

I did notice that when the performance drops, the fan speed also decreases. Although I have set fan RPM to MINIMUM 3500 RPM under Wattman/Overdrive tool. Can someone suggest why the fan speed might be decreasing automatically and if there is a way to sustain a high RPM? Maybe it DOES have to do with the card thinking the system is idle, so "let's power down" Huh

But that doesn't explain the power profile or the HDMI dongle (the HDMI dongle has worked in other situations, so not sure why it wouldn't with Vega).

Hopefully, someone can figure out a fix. Very annoying to reboot or restart the miner every 10-12 hours.

Thanks!

hwinfo64 works fine with vega, no speed decrease or lockups. Just disable GPU I2C Support in settings.

I think I made it stable. I disabled all "weird stuff" from hwinfo, including direct hardware access, i2c ecc. Don't know exactly what, but it's showing temperatures and not blocking any more

3 vega 56 flashed with the 64 vega rom

max i can get is 1500 on all three using CAST-XMR , on top of that the hashrate keeps dropping after a high start and settles in at 1400ish

using 1110 core and 1075 mem 20% + power lim and 900 mv on core and mem

Any help ? i see 1200 before i do the disable enable trick , and I do see the error that says blockchain drivers not detected

but I am using the robin hood blockchain drivers , the aug 23 drivers seem to constantly crash my system

you need the blockchain drivers aug 23. no way around it. if desperate, start with a fresh windows install.

yeah even on a fresh install BSOD when i run it ok thanks tho

The fact that you start strong and go lower after a little while suggests temperature problems and card backing off. You need manual voltages too and the registry hack because it lowers the floors on the voltage on P1-P6 which you cannot touch in wattman.
The bsod (in my case) means that I'm pushing a card beyond what it can do end it either locks up in the driver (bsod) or if I'm lucky it stops in userland and it cannot be "connected to" anymore. It's kernel will show 0 hashes.

Best way is to use registry hack + overdriventool to set your per-card profiles. Test them one at a time. And write down everything.

Atm it's a pita I know. Takes time to stabilize if you're not lucky and have cards that manage all settings with ease.

I also have this strange problem with decreasing performance over time. I verified it's not related to temperature.
It also goes away immediately if I restart the miner.

Same here. I have posted twice about the problem and tried everything that was shared as a solution (clean install, max RPM, high power settings, etc.). But no go. Waiting for someone to share a proper solution. I have 12GB RAM and nothing else running on the rig. Very annoying to restart the miner every 18-20 hours after performance deteriorates. Thanks in advance for whoever shares a constructive solution.

I think I now figured out why performance degrades after a while with CAST_XMR.
It seems it's related to the power setting and the monitor turning of after a period of idling. Performance goes down when the monitor turns off.
This is true if monitor is connected to one of the mining cards. This explains why many don't see this problem because they use IGP.
I have set monitor to never turn off and now performance stays at ~1900 indefinitely.

This issue has been reported before I think. Has something t do with the HBM. You can either leave the monitor on or buy a HDMI dummy plug.

I've got one card that just always runs 10deg hotter, no idea why.

any tips?

Set your temperature target for that card and the fans should try to keep it around whatever temp you set. It’s very easy with Overdriventool.

Also for those worried about fans dying, there is a max temp setting that shuts the card down in case the thermal limit of your choice is breached.

Can be the silicon lottery.
That also happens if there is the slighest anomaly with cooler alignment or TIM application.
You could check it by taking the cooler apart but then warranty is void.

Initially, I saw reports of some VEGA cards having very bad TIM and users getting 6 - 10 C improvement by applying some good TIM. So I took one of my cards apart and installed a high end TIM. I didn't see anything wrong with the stock TIM and it looked exactly the same as the one I applied. Afterwards, I saw a slight increased temperature on HBM compare to before and compared to my other cards.

If you are serious about getting to the bottom of it, you could swap coolers between two cards and see what happens.

Anybody having issues with monitoring the health of their rig ?

I an experiencing continuous lock-ups in cast-xmr (and stak for that matters) when I'm running hwinfo64 or gpu-z to monitor the health of the rig.

It's imperative to know temperatures on the hbm and monitor fan speeds.

4 GPU + single PSU is OK. On 8GPU + 2PSU the lockups are frequent (every hour - two).

Any other options ?

hwinfo64 works fine with vega, no speed decrease or lockups. Just disable GPU I2C Support in settings.

I built a console app to get GPU temperature and fan speed, give it a try Cheesy

Guys please help me!
I want to buy AMD VEGA 64 or GTX 1080 TI, which one should i buy to get better kH/sec ?! I care about price aswell !

Get a Vega 56 (any brand) for $399.

any idea what is the power draw of a vega 64 hashing monero? vega 56 hashes at about 160w?

Mines are about 168W...

i take it as you optimised it and hashing at 1950~ ?

Just 1400core at 905mV and 1090mem with 900mV.

What program did you use to set the voltages? Also have you modded bios at all?

OverdriveNTool,
Bios isn´t moddified.

Me too. So, because of this, I gave it up tu run such of this programs...

But it's risky without. A fan can fail. Even by software bug. It's good to be able to shutdown or alert automatically.

Hi guys,
I am just received answer from amd on my question about missing option for gpu workload on vega:

Vega products are already optimized for GPU workloads, so there is no toggle provided or needed.

Please ask them next time what I'm doing wrong... https://www.reddit.com/r/MoneroMining/comments/7ap7dj/vega_10x_rig_two_news/
