How do you fight the "GPU COMPUTE ERROR" ? I guess I should not put 1100 on all 56s - but is there a way to tell which one should be put at lower level? Like 1080 or so ...

I already had 4 Rosewill Lightning 1300s.  On my two most recent rigs, I used hellae's recommended EVGA 1300W supernova Gold PSU.  (IMHO, these are overkill, but likely quite efficient.)

Hi Guys,

Which power supply do you use to power 4 Vega cards ? Maybe you use 2 PSU?

Thx

I reconfigured 4 of my old Asrock 970 Extreme3 r2.0s and setup 2 new Asrock H81 PRO BTC R2.0 LGA 1150.  The downside of the 970s are limitations to 4 GPUs each.

Hi Good Job !

Which mobo do you use?

Thx

So I completed the tent project for the 24 Vegas.

Here's where to buy the tent:

Here's the 8" duct fan to carry away the hot air:

Here's the 4" duct fan to carry the heat to a room (for cold winters) above where the tent is located:
https://www.amazon.com/gp/product/B01M7S46YZ/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1

I also use 2 8" personal fans to blow in cold air at ground level into the tent.

The tent is in a basement.  I had to bust through the brick and install an outdoor register vent.  Mine is just above the basement doors.  I connected about 10 feet of 8" insulated flex duct to that and into the tent.  I bypassed an existing 6" flex duct and routed it to the tent, stepped it down to 4", to heat the room above if needed.  The fan for that duct is controlled by the web power switch outlet.  The 8" fan runs continuously to the outside.

Inside the tent, which has plenty of room for more rigs if this experiment works, is a simple 4 shelf wire shelving unit.  Six open air wood frame rigs fit nicely on them.  I suppose one could just build their rigs directly on the racks.  The ethernet switch, web power switch, and monitor (when needed) fit on the top shelf.  I access these headless rigs with TightVNC.  I had previously run 3 separate, dedicated, 20 amp circuits to this room. 2 rigs (4 GPUs/each) per circuit.  (Having said that I doubt that I will run more circuits down to this area of the basement to fully utilize the size of this tent.  I have a little buyer's remorse and now recognize that I could have gotten away with a tent about half this size.)

The Vegas are stock 56s and using XMR-Stak as described here:
https://www.reddit.com/r/MoneroMining/comments/74hjqn/monero_and_vega_the_definitive_guide/
I use the DevCon batch file to initialize the miners. They average 1800 h/s/GPU.  The GPU fans are set to keep the GPU at 70F with OverdriveNtool. (I may BIOS mod and registry hack later.)  Just concerned with heat dissipation currently.

Now for the heat details:  I approached this problem as if the temperature inside the tent would be analogous to the temperature inside a gamer's computer case.  Most sources I found stated that those temps could easily be in the 50C range.  So I knew I had to beat that to protect the hardware.  Sapphire tech support got back with me and stated that the maximum acceptable operating temp for the Vega 56 was 92C. WOW!  The average temperature of the basement is 64F now and never higher than 70F in the summer.  I utilized the motherboard's temperature sensor as well as an independent simple outdoor thermometer dangling from the top support inside the tent.  Without the 4" fan in use, the tent got up to 112 F (44C).  That was good, so I used some other ideas to see if it could be improved.  I placed four 20" box fans behind the rigs.  As was previously stated in this thread, it hurt the cause, it did not help.  Unlike when in use behind double dissipation GPUs, the blowers on the Vegas already direct the exhaust "forward." So the box fans remain, but are turned off.  With the 4" fan in use, I got the temperature down to 102F (39C).

I hope this helps anyone who is contemplating going about trying this tent concept.

I'm confused.

the definitive monero guide says use 1 of 3 reg files (1100MHz HBM @ 905mV,1050MHz HBM @ 905mV, 850MHz HBM @ 905mv) then the page references a youtube video that uses reg files from a overclocknet page, morepower vega64.  so which is it?


My main PC (win 10 aug 23 drivers, vega 64, 16Gb DDR4 ram)
At first I tried the 1100MHz HBM @ 905mV file but after a while it doesn't work anymore and I ended up using 1 of the morepower reg files and I have no idea which is the one I used. How do I tell which is the one I used??

Also, gpuz ver 2.4 doesn't show the power draw, in fact it shows very little data. I had to use hwinfo to show the core and memory power usage of 56w and 27w respectively.

2nd PC (G4400, biostar btc250 pro, 4gb of ram, 50Gb of virtual ram, windows 10, oct 23 drivers)
either way, I can't seem to get 1 of the cards working. whenever I have 5 cards together, there will be 1 card that shows a code 43 error. overdriventool says gpu is not recognised or driver not installed. But when I tried 1 card at a time, it hashes ether nicely but draws too much power. Gpuz ver 2.4 says it draws 220w.

overdriveNtool behaves in a weird manner as well. 1 of the P states for the core shows 1420mhz  and P3 state for the memory shows 1150mV, power target is blank and when I tried to set the limit to 70, it gives me an error about being unable to set power limit. After closing and restarting the ovedriveNtool, it suddenly shows the stored values of the profiles I used for my main PC (above)

Depends which route you take.  I prefer OverdiveNTool and not even install amd software, but most people start off with wattman.

I thought it was important to never open or use Wattman with the vegas?

Thanks. Now it seems one of the them has an error in device manager

Easiest way to identify which ones to flash is under device manager.  Right click the GPU you want to look at and select properties > Details tab > scroll down to Driver Key.

Looks like this.

The important part is resetting the GPU's to default in wattman after you have used the registry edit on all of them and rebooted.  

Here is another informative site to help.

i have some questions for you or anyone who's familiar with this card

I installed 5 vega 56. flashed them and in the windows registry, instead of seeing just 0000, 0001 to 0005, I see 12 folders 0000, 0001 to 0011.

some of the folders mention rx vega but I didn't check all of them.

I ran DDU twice and i still see 4-5 folders and except for 0000, the other folders contain just 1 line of generic info.

if i still see 12 folders again, Do i still run the reg mod file and edit the target folders for 0001 to 0011?

wooow
temp is high
down your temp
73 is very high - set fan min 3800 rpm

its working two cards.

What does it mean guys? Does it mean my GPU1 not working?

https://drive.google.com/open?id=1FodDW8sjHydaHtsM3xQhDkZmzheF7sp2

I'm using the 800 mem powerplay table as per hellae's reddit.

I then push up the mem to 1100 and down the gpu to 1350.

are you saying i can use that saved profile in odt even without applying the registry setting?

Click the miner window and hit Q just like you pull up the stats with S key.

I pressed Q, nothing happen O_O

Pls doest win10 have something like crond in linux?
I would like to setup restart xmr cast every 30 minutes.
Thanks.

PS: Issue solved
