Any word on amd vega hash rates?

[Hellae]

no, the speed of the card is stable. I could not make it run with the mod, as it was crashing. So with manual downclock via the wattman its not accepting the fixed values for the gpu clock and is running different MHz.
The manually adjusted 1mV card - how come 0.1mV make it draw double?

Whats the danger zone temp for the HBM2 ?

Manual downclock in Wattman or OverdriveNtool makes nothing with blockchain drivers except for the case you hit some special ("bug") value.
Funny, all monitoring software will show 1000mhz clock (for example if you set 1000) but in fact it will be default clock.
Only trusted values are gpu voltage shown, mining speed and power-meter@the_wall readings.
And yes, difference between 1222@0.82v and 1500+@1.05+v is more then 130watt when ETH mining ))

I have no info about danger temp for HBM2 but I strongly recommend to keep it below 70 degrees.

Uhm ... I was walking about the difference in consumption between 1222@0.82v and 1222@1.05v . As the other values are fixed by the mod. I adjusted the voltage manually with the Wattman, and it really accepts that setting, as I see no variations in GPU-Z.

About the 70C ... I cant imagine how this can be done to be honest. The cards running at 58C have HBM2 at ~75C. That at ~18C room temperature.
What exactly needs to be done to cool these?

Just increase min fan speed to values above 3000. It will be loud but will cool down the memory.
Never ever leave min fan speed set to auto, as its RPM will be defined by the cooler GPU Core, ignoring mem temperatures.

I know that, they are not at auto. Still at 70% fans, thats like 3400 RPM, the HBM2 temp is as I said around 75C. I can probably push em even further, but running like this 24/7 is asking for trouble.

What kind of extra cooling are u guys using? Adding side fans , blowing from front to the back doesn't really do much.

75C degrees is for 1V cards or for 0.8V cards too?

[l1xx]

no, pretty much all. HBM2 is 15-18C hotter than the card on each. When gpu temp goes over 65, the HBM2 is over 80.

With the other driver, with lower clock and especially the lower power draw, the temps were ~15C under the values I am having right now.

That suxx. I have only liquid vegas now and they keep hbm bellow 65C even hard dual-mining.
I ordered Vega56 (on air of course) - will check soon.

I also notice huge difference with same settings on different cards. I have two of these running at 54-55C with 62% fans, where others are at 61 with 70% fans ...
That whole thing is a huge lottery it seems.

P.S. You said u are using different settings, no ? Maybe if you share em with us, that may improve things

My settings take more power with higher speed. And more stable (for my taste). But they won't help you with overheating comparing to 1222 mod and I prefer to keep them private (0.4 eth fee). Maybe you should wait for Oldcomer's new video. He promised new settings for XMR with higher speed. Maybe it will help in your case.

[l1xx]

fair enough. I think if someone finds a solution, how to decrease the power limit without losing much efficiency, that should solve the heath issue, as I had noproblem with the underclocked cards at -24 with the normal driver. 

But not being able to do tweaks with the wattman on these blockchain drivers is bad. Hope they release another driver, but I seriously doubt it.

On Vega56, I use the Power Level at -20%, hash rate is stable at 1830, total system is at 560W (with 3 vega 56).

The more I read the more I want to stay away from Vega 64 Air cooled. More power or way more tweaks needed to reduce its consumption to have more ~100H/s for more 100$ seems not a great deal.

[l1xx]

well, can't change that anymore I will check the situation to Monero and maybe will just switch back to the other drivers.

What clock settings are u using for the VEGA 56 to get the -20 to be stable?

[fr4nkthetank]

just got my 2 vega's in the mail, although im really busy these days, just had time to install them, blockchain drivers, win10, etc.  standard stuff.  but xmr-stak refuses to run.  sucks because I have no time for that shit   if anyone has an idea why, let me know.  so its dual mining now, about 190w each.  too high for me still but these need tinkering.

I couldn't get it to work either so I'm using sgminer on Win10 64.

thanks for the reply, yeah claymore has an update with vega support maybe coming today, itll probably be just as good as xmr-stak I think, well see.

Check my tutorial on page 26 of this thread. It's just basic slider settings with no voltage workarounds.

hi
i have question
how see Stak Web
and whats different between pool results hash and real hash on PC?

because i have -15%

To enable the stak web interface check the config file. It's one of the last few items. By default is set to 0 (disabled). I've set mine to 16000, so I access it at http://machine-ip-address:16000

We all talk about Pc hash rate counts here, but what really matters is what the pool is actually counting, sometimes more than PC hash, sometimes less. The day average should be pretty much aligned with your PC hash rate. If it isn't, check the R results, to see if some shares have been rejected or expired, and C connection to check the health of your connection with the pool.

[Jackkyy]

ok
thanks
see my results - no errors all is ok
but on pool i have 1.67 kh/s average

maybe pool is bad?

Checked it. -30% Frequency, are u sure the cards are really holding it? Whats the stable freq they work on, can u check ?

They fluctuate between default P5 (higher value at 1400s) and 1300s (with the -30% freq on the slider). Can't really tell if it's jumping between P5-P6 or P4-P5 given the PL set at -20%
At the wall, the power fluctuates between 560-570W which is normal to me.

I'm waiting for an Oldman's video related to monero to try out the regedit way.

In what income is related, the 3 cards are aligned with what the monero profit calculator tells me: ~0.097 XMR for ~5500.

Before nanopool I've been a week in a smaller pool, also stable with the same settings and silimar income. Stopped to be similar after the hard fork, that somehow affected the pool block discovery ratio, reason why I switched pool.

Hello guys, building a 6xVega XMR mining rig, need some advice.
Parts:
Asrock H81 Pro BTC R2.0
Intel Celeron G1840 (can't get cheaper CPU)
16GB DDR3 RAM, I already have this
250GB SSD

My problem is Vega 64 and 56 are the same price (600 euros). Should I buy 64s or 56s?
Is there any point in buying a Ryzen CPU instead and have it mine as well?
Thanks in advance.

I wouldn't go with 6 Vega now, to many problems can be. 4 Vega+something else (Nvidia for example) should be fine

What kind of problems?

See (https://bitcointalk.org/index.php?topic=2201970.0).  In short, it seems we cannot easily enable HBCC on more than 4 cards.   I had it working on all 6 at once point, rebooted, never been able to get back.  Read the first post, I've tried everything short of nuking Windows entirely.  Others are reporting the same issues.  

What I wouldn't do for some trick to avoid having to disable/enable HBCC on every card after reboot to get 1900+H XMR.  

Also, regarding the power table mods.  OLDComer's mod works on 4/6 Vega64's I have.  The same two cards I cannot enable HBCC on also seem to ignore the power table registry settings entirely.  Likely a clue there but I am not sure what.

Hello,

can you share your settings? i have 3 vega 56 too
