"extra information: i spend nothing for electricity"

No reason to go with 470s at all. 390/390x is definitely the way to go with zero power cost.

better build 5x rx470 4gb rig.

Advice is : Don't invest what you cannot afford to loose...

I mined BTC with a GPU years ago and had your same worries.

I had the opportunity to buy an early SHA ASIC but was too worried because of the investment cost and thought I would never ROI and eventually gave up on mining all together until BTC price exploded. (I still had 1BTC on a pool wallet which I forgot about which was a nice bonus)

This story pretty much repeated itself with Scrypt ASIC and I left mining until this August and now I am not leaving again.

If you are not paying the power bill you cannot loose, you will always ROI pretty much regardless of anything.

I think we are still seeing the beginning of crypto and a revolution in how we use money, where it comes from and its properties.

thanks for your response guys.
i have another question,i wanna build a rig that contain's 4 asus r9 390x dc2 8gb and 1 rx 480 4gb
actually i feel fear when i think about this, i wanna spend alot of money and i am afraid  of altcoins gonna be cheap in future. what shoud i do? is this predict possible?
mining of etc and zcash is profitable in future?
can you give me advise?
extra information: i spend nothing for electricity

what about it's h/s?

better build 5x rx470 4gb rig.

Great I will try that.  What are your settings and results with the 1750 strap?  AND Thank You!

I did some tweaks on both of my Tahiti (HD7950) cards and I get around 200H/s per card. Makes 400H/s in total. I'm pretty happy with these results.
Thanks Claymore for this great program. Keep up the good work!

All of my MSI RX 470 Gaming X gpu's now have the Samsung memory on them.  They use to have the Hynix.  Has anyone had any problems with 1500 strapping them?  I know there were issues with the Elpida memory on the sapphire gpu's.  I do not want to brick them.

currently the average is around 220 h/s

Guys,I want to know about RX 480 4Gb h/s in claymore
can you give me a hand?

Hey guys, I'm having a bit of a problem with one of my rigs. This board seems to be trouble lately, and I'm not quite sure why...

I have an RX 480 and 2 R9 380's on this rig, one in slot, the RX 480 in a slot, the 380's both on powered risers.

For some reason, after about 20 mins of mining, I keep getting the "GPU Thread Hangs" error. Unfortunately, it isn't restarting on it's own, so I have to be lucky to notice. I've tried undervolting, underclocking, etc. I've gotten it to go for about 2 hours, but the threads keep hanging. Then I thought maybe it was because I'm mixing cards. So I disabled the the RX 480 and had only the 380's mine. Same problem. I disabled both 380's with only the RX 480 mining, same problem.

I just tried lowering power limit % on all the cards by ~5% and lowered clocks to see if they'll run stable. Only time will tell I guess. Same thing was happening when I previously had a 390 and a 380 on this board. But I moved those to my main computer, mixed cards and all, no problems. Sometimes hangs once a day on all my rigs, so that still sucks. But I stay pretty much on top of them. But this one board just perplexes me. I think it may have something to do with the power delivery or something. I got it used, and it was fine for a while with Ethereum mining, but then it started acting up, and is now on Zcash as well. It appears to be more like a Phenom-era AM3 board, using a Sempron 145. I've pretty much ruled out any kind of CPU bottlenecking, as it does mine at proper speeds... Until it hangs.

Any suggestions?

1500 strap is no good for Samsung. I suggest 1750.

Guys, I have a system with 5 GPUs, 3 R9 290 and 2 RX 480, all using usb risers with sata/molex adapter. He's been standing about 3 months 24/7. Today I smelled something burnt and found what is in the picture. Just the two that energized the RX 480. Do the RX 480 continue to extract more than pci_ex can support? Is there something wrong with my PSU?

My RIG:

Asrosk H81 Pro BTC
Intel Celeron G1820
8GB RAM
3 R9 290 + 2 RX 480(all stock)
USB risers
Cougar GX 800 + Corsair CX 750

Hmm... Either way, Samsung is said to be best for mining, right? Which variants have Samsung memory? Or is it mixed and matched, even with same card model? Just wondering...
