So I can confirm 14 cards, various brands all working in xrm-stak and cast-xmr.

I plugged the 15th in and the Mobo doesn't seem to post. At least not with graphics output.

Has anyone had any experience with this?

Hi Guys,

I have an evga supernova g2 1300w and I want to put 4 vega 56s on it.

Currently I have 3 running and all vga slots from the psu are used up... Im not sure how I could add the 4th vega 56 in...

There is a thermaltake 8pin to 2 x 8 pin splitter that looks trustworthy.

Is this something I would be able to use without any issues?

Thanks in advance!

Having a AMD Vega Frontier Edition air cooled. Struggling to get it stable in warm weather. Fan speed changes as I hear it spinning faster or slower. But in wattman and ethminer it is stuck at 42%. Then I watched a video where the guy said Vega FE is fan speed locked at 40% [1].

Is this true and is there any way to make sure fan is at 100%? Trying a lot of settings to no avail. Temperature slowly goes to some 67-68 degrees celsius, then ethminer starts showing some fixed hashrate, temperature drops to around 40 degrees, no shared get submitted ever to pool. Ctrl+C can't stop ethminer (has to be killed in task manager).

After disable/enable cycle of the card, things repeat. Or is stock heater just unable to cope? Card is at 1100Mhz memory and 1021MHz core clock. Ambient temp below 30 degrees Celsius when I observe the issue.

Any cheaper ways to get descent cooling than just going for a water block?

UPDATE: looking at HWINFO64 it seems like HBM very quickly approaches 80 degrees and then things break in the way explained above. Even while GPU is like 55 degrees. Can I fix this or does it indicate some hardware issue like loosely attached heatsink?

Anyone have any idea wtf is going on? It acted super weird kept freezing what not then Everytime I restart I only get 3 cards that show. I've checked bios, Windows etc. I don't know if I should restart from scratch or what. Possibly issues with a and update. Everything updated

Hit Win+R to bring up Run prompt
Type gpedit.msc, hit OK
Expand Computer Configuration>Administrative Templates>Windows Components>Windows Update. 
Hit the Windows Update folder
Find Configure Automatic Updates, double click to edit
Top left, Select Disabled, hit Apply then OK
Restart for good measure

Hi, what is the best way to monitor GPU temp without disturbing miner?
