Cryptocurrency Mining

So the penny finally dropped on how the payout scheme works on ehtpool.org. I like the share system but I'm wondering if this is the way to go for a small rig? Estimating that 5 x 1060s will do about 100mh/s right when I get to full speed at the end of the month. Could be worth it in the long run, but so much can happen in the next few months. :o

I might also have to just concede and go the nicehash route or perhaps move to nanopool or dwarfpool with more regular payouts. Anyone else just doing eth, what pool are you using?

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.

I've also read recommendation not to use the sata connectors, but they do also concede (as you've mentioned), that running one per cable is probably fine.

Neat rack, I will post some images later today or tomorrow

Lel at that fan.

Haven't changed my driver version yet, but I still cant go over 380 (and that's at 100% power) :cry:

Which driver version? And Windows version? Sorry if you have posted it earlier on and I maybe missed it.

Any OC applied? Which brand of card?

This setup yields me around 395-400 Sols on a Zotac 1070

Pretty much the config I had before. In Afterburner (I assume you use it but any management app will do) can you see the graphs and if any of them are telling you whether there is any throttling on the card? Are you using the card on a riser?

I hear what you're saying, but the PCI-e bus lane is limited to 75w, the board won't even boot if the card draws more.

*raises hand*

I have a funny story to tell regarding this. Got my 1070 and plugged it in - boots to desktop but fails when doing anything graphically intensive. Turns out I didn't plug the modular plug on the PSU side for the 8-pin cable in properly and I was running the 1070 off the motherboard power alone :D

So it may boot, but it will be unstable as all hell if you apply any load to it. YMMV of course :)

8GB+ going forward, will use the 1050ti's to mine whatever else on NHM.

11GB is the next batch, one more 120 card 1080 batch and then it will be 2070/80s September and will be selling all the 1079s by then,

What does that have to do with this?
You try run 3 GPUs risers from any cable, and lets say the each riser draws the full 75w. You've got to supply 18.75A on a single 12V wire, which will typically be 18ga and have an ampacity of only 10A... So even if the risers draw half the power they are allowed to request you can see you'll be on the edge of what the wiring can take. Nevermind that as explained the terminals will be way way out of spec
