Any word on amd vega hash rates?

[ben8jam]

Yours is pretty different from the 1100mhz 905mv version that we're all downloading. I just have no idea how to interpret all the hex.

hi :  PSU EVGA 1000 GQ, 80+ GOLD 1000W , can hundle x4 vega 64 ?

Yes, if you undervolt or reduce power target enough.


So that would have been helpfull to know, that you need atleast 900mv or more to be able to increase SOC clocks... I dont want my cards to use more power, since id need to increase fan speed. Im sticking with 1100mhz and 865mv.

That reddit link on the previous page says you might need 950mv to oc SOC.

I'm not sure you need more voltage for soc and hbm overclock. I'm using 900mv (that leads to 875mv in hwinfo64 readings) to keep gpu stable @1408. If I go lower gpu clocks then xmr speed decreasing quite distinctly

you gpu actually run at 1408 ?

because i put in msi -120mv   (i tried more but ring crashed)
power limit -22
it put the clock at 1352 but actually don't matter what clock i put  because it always get up and down and it s run average 1450+

Thats alrd quite a leap 865 to 900mv :/ Maybe i could run these 4 with higher consumption for now, but when im adding 2 or 3 more, my fuse cant handle it

Only have 20 and 10A fuses, 20 is for oven and that tiny 10A is for everthing else. Cant use coffeemaker, microwave and my rig on same time xD

gpu is running with const freq 1408. I'm not using afterburner or radeon settings. I'm not adjusting sliders ))
And I'm using 23Aug drivers ))

First I connected the vega 56@64, installed the driver, then replaced it with 64, I think it's somehow related. After rebooting hashrate drops to 2000 and that would get 2500 I need to remove the driver, insert the vega 56 and so on

I cannot reproduce ... I swaped rizer cables between my flashed vega56=>vega64aio and native vega64aio. Speed stays the same, 2k for v56 and 2.07k for v64

I do not understand how this works. It looks like a combination of magic and drivers.

[martyroz]

No need of SSD for virtual memory. Just need space for swap file bigger then combined GPU memory of all cards installed in system. No massive swapping occurs.

Thank you so much for your reply

Sometimes its the sequence of the clocks and reduced voltage and power limit that allows it to go more stable then normal.  I find if I suddenly switch from low clocks to a completely different setup its more likely to crash, this might be because of SOC clock not allowing the higher memory.  I sometimes notice SOC has come way down below 1100 so even if I increase voltage to try higher memory speeds it doesnt like it as SOC is a limit generally.   It might require to have intermediary profiles to gradually raise the clock before it can be left stable.

Also turn off all windows graphical effects if you havent, leave it on high performance.  an open web page is not a good idea also

When i disable my new Vega 56 and re-enable in device manager, it cannot recover to OK state. Instead an error is shown, the device is not working properly, sometimes even BSOD. When i restart PC, the GPU is working OK again.

Tried reinstalling blockchain drivers with DDU, switching risers, cables, but did not help. Do you have any idea why this is happening? (i need to do the disable/enable process for monero mining)

You have a bad GPU. Took me days to figure it out. Get it replaced.

How are you guys getting sub 50C temps hashing 2k on Vega 56s?  Are you blowing freezing air on them or something?  I'm at 68-70C doing 2k at room temperature and with a 120mm 5 fan array cooling.

Some of my Vegas hover low 50's while a couple are high 60's under full load @1408/1100.  Either its silicone lottery or just inferior thermal grease/pads.

[dmitrik]

Is it strange that I'm getting those results (2k hash rate, 70C temp) and my clocks are 1112/950 +50% power?

I haven't played with +power% but that would definitely increase the heat generated.  Did you flash a 56 to 64 BIOS and using the proper settings or just default 56 with cranked power?

6 card rig with about 10cm spaces with fans ~1800rpm and no additional cooling. No problems keeping it under 60 at ambient about ~19-20c.

This rig pulls between 950-1050watts from the wall. If you are having temp problems your under volt probably is'nt working because @ 150W per card the temps should'nt be a problem.

Thank you rednoW for sharing your reg file. Its the first where iam able to boot into Windows. Both Vega56 with 64 Bios runs at 2kh/s with ~140W for a minute or two and then the AMD Tool crashes or one GPU crashes and resets to default settings. Also if i reduce mem to 950mhz and rise voltages to 1100mV its unstable. Bad luck in silicon lottery?

[l1xx]

@rednow, what are the default values with your mod? Can you share an overdriventool screenshot too ?

Something not mentioned in hellae's guide (but is mentioned in the comments), and something that I've lost a whole day to - you may need to up the voltages to 930mV. One of my cards would cause BSOD with all the reg files that I've downloaded, and even at 920mV - even with quite conservative clocks. Now runs rock solid for days on end at 930mV with fairly high clocks. I am sure it does affect consumption, but it is not like I have any choice!

To be honest, the 1100 mod in Hellae's guide has to be avoided for full 6 or more cards rig. Its better to use the Oldcomer's mod, as its way more stable. And then you can bring down the voltages with overdriventool after some stable run time. Going the opposite way cost me way more time to figure which cards cannot handle 900mv ...

Did you set target temp to 50-55 degrees?
Also you may need to fine tune fan speed. HBM @ 1150mhz will work only if its tempis below 65 degrees.

[rednoW]

My reg-file mod is based on vega564 liquid bios.
Only changes are to set "greyed" low power state voltages to 900mV (905 or 910 if you are a silicon lottery loser) and increase SoC clock to 1200.
All other settings are done in OverdriveNtool as I wrote before.
I didn't touch gpu or mem clocks in power play at all.

No Target temp was higher but temp was arround 40 degrees when it crashes. Gpu hasnt enough time to heat up. Will try it again later to find a stable point to start
