Cryptocurrency Mining

[Gtx Gaming]

I was trolling, I don't have a son.

8% away from my first payout to myetherwallet. How do I sell it?

Shapeshift to btc on jaxx , then transfer to luno.

No

EVGA

65% power
122 Core
650 Memory

Gigabyte with extra 6 pin

70% power
0 Core
545 Memory

The EVGA was the one that disappeared few times

Most likely unstable oc.
Run it stock to verify then try 110 / 600 / 85% and check if you are around the standard 150w tdp. If stable then you can further fine tune the core clock and power to suit your power / hash rate requirements. If low power usage is your end goal then drop the core into the negative but at the expense of hash rate of course.

Thanks, i'll give it a try.

Hmmm, unless there's a massive hashrate increase I don't really see these selling well.

I'm not convinced either. Those hash rates look similar to the bios mod rates and the price doesn't look great. Plus where is the resell? When the difficulty goes up and the card falls behind who's going to buy it?

Either the hash rates need to be significantly better or the price needs to be very attractive.

I've tried that. Doesn't work.
What do you use under default video settings? IGFX?

It will certainly work, just a matter of for how long. But if you're running cards at sub 100w, and they have an 8 pin power connector (which can supply 150w) then maybe you get lucky and it is all drawn from that connector. Maybe you don't and because you thought hey, this sata power cable has 3 connectors on it, that means I can power 3 risers, so now you're stressing the wires and the terminals and things get hot and eventually go poof and the magic smoke gets out.

Easy test, just feel the power cables going to the risers, if they are warm to the touch you may have an issue.

Yep, should've listened to you. Had one cable melt on me today.

Fck me...

Will give it a go later thanks

It didn't smoke or anything. 2-3 of my cards would suddenly just spin up and go full blast and shortly after I would get a bluescreen.

Fired her up again, same story as soon as I started mining - fans full blast and blue screen.

Reinstalled drivers, reinstalled windows even. Only after that I looked at all the cables.

It melted at the psu plug though and not at the actual sata connector. I had 2 cards per sata cable.

Anyhow, molex cable all the way directly from psu to the riser now. She's up and running again and stable.

Thanks for the heads up. I was willing to brave 1 riser per SATA cable but might give that a miss now. What PSU are you using and what is your draw at the wall?

I'll have to spend serious time inspecting tomorrow.

Mixture of EVGA 1000, 1300 and 1600

I have 2 Sata per psu cable some rigs all 3....


Realiaizing now that's a k@k idea.

 

[morkhans]

There are probably a couple of factors in play. Quality of PSU, quality of cables, quality of the riser and power draw on the card. Weakest link most certainly from the reading I've done is that the SATA power cable wasn't designed for the draw a gpu in a riser needs.

Running a corsair ax1200i.

Drawing around 850 from the wall with 6x 1070s with current power target set to 75. Dropping it tomorrow again to 70ish and it should then be around the 780-800 mark.

Yea. Am worried now to leave it on mining while no one is home. Already took my fire extinguisher out of my Jeep and parked it next to the rig

I woke up this morning to a flashing white LED next to the 8-pin connector on one of my 1060's

The other cards are fine, just that one. So I swapped the power connecter to another card, and now it's doing it on that card! SO clearly something up with that power source.

The strange thing is that when I mine ETH I don't get the issue.... Only when I dual mine ETH and SIA. Perhaps its a higher current draw and the card is not getting enough power? But that doesn't explain why the other cards are not doing it as well.

Any ideas?

 

[JerryMungo]

Bad cable? PSU?

swapped connectors around, made no difference. Cable seems abnormally warm to the touch though....

Dual mining will draw more power. Most people suggest the extra power draw (and subsequent strain on your components) isn't worth it. Just mine one thing.

Decent enough PSU, so hopefully the switch to molex only will avoid any further scares.

I had to have a chuckle at the fire extinguisher. :crylaugh:
