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

better build 5x rx470 4gb rig.

"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.

I don't think this is necessarily true. I guess without power cost, maybe. But poster above is right. Beefier power supplies etc, make costs go way up. Likewise, try finding a 390 for less than 200, even used. Lowest I got mine for was like $185 out the door, but got lucky on ebay. $200 is more typical...

Figuring that in, it costs more per hash than RX 470's... Although it may be balanced out by having to buy more motherboards, RAM, etc... But for me, where electricity still matters to some extend, the 470's massively lower w/sol would be my choice... Just for anyone wondering what the better deal *might* be in their circumstance.

No. Going from 470 to 390/390x on a 6 card rig will require at most an extra 700W. That's a $100 PSU. If you don't think spending $200 ($100 PSU, $100 or so on GPU's) more to bump hash rate by 40%+ on free power then you shouldn't be building a rig to begin with.

Already without the latest update promising even more hash/s on 390/390x they run close to 50% higher than 470s so with NO power cost. It's a total no brainer if you are building a rig.

Well, will we see 10.0 tonight?

Have a little patience , my friend

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.

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

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

I put the 1750 strap on the Samsung memory gpu's and 1500 strap on the Hynix with equal results!

Thank You Q_R_V !

I am planning on building a mining rig with more than 8 gpus. I've bought 1 to 4 pci express splitters but I had no luck getting the motherboards to boot with more gpus than the number of its actual physical pcie ports. (tried z87, h97, h81, b150). The person who sold these to me said he heard ASROCK X99 EXTREME supports up to 32 GPUS.
Now I've seen somewhere on the ethereum dual miner thread that somebody managed to use around 18?, i think, amd cards on linux, but I cannot find that post anymore.
Anyone have any info on this? Will a motherboard with X79 chipset be just as good, as they have the same number of lanes? Or it depends more on the bios ?They are rather expensive and I want to hear some opinions before I throw my money.

Most miner software doesn't support more than 8 cards. (hardcoded in the client). I ccminer sp-mod I support 32 cards, but NVIDIA only.

Looks like a great plan, but I'm wondering if you will manage to get your ROI back. Do you have a certain strategy for that? WIll you mine different coins from time to time like XMR or ETH?

Really it's a more like a for-fun project, to get things a bit to the extreme, although it should pretty much lower my ROI or keep it the same, not increase it (i will save the cost of 3 mobos, 3 cpus, no ram (will use 16gb on it), and the cost of about 2 psus - although an x99 mobo + cpu is a lot more expensive, it will be actually easier to resell one of those at good value than four  crappy h81 btc pro and celerons which nobody will want except at shit prices when mining will be very little profitable for most people and the markets will be full of second hand mining hardware)
I will use a 2450w psu to power the pci connectors of the 28 cards i will use (7 slots x 4 slots per spliiter, already have the psu online). Right now they are mining on 4 rigs with 7 slot mobo each. I got the server psu for $55 including shipping. and the connectors cost like $20, cables another $20 and a friend soldered them for free. so $95 for a 2450w psus is not bad. And for the risers I will use either a 2000w  computer psu or two 1200watt ones which I already have.
I am not sure how many amd gpus can windows use with the amd drivers, but I think there is no limit on linux and claymore's support 32 gpu as far as I know. Or was that 16?
The only concern would be stability, if one card crashes it could hang the whole system.
So please, if anyone has any info on more than 8 gpu on one system.. please enlighten me, what motherboard would be best?

For one, an increase on Claymore miner's hashrate means difficulty goes up because everyone gets the increase. Second, yeah, if you are not paying for electricity, I can see the appeal of R9 390's. But 300 sol/s for 300 watts (ususally hashrate never gets that high...) vs ~210 sol/s for 100 watts sounds like a better deal to me. Well, mostly if someone were only building let's say, one 6-card rig. But I did make an error before. I guess when you consider not paying power, and also the additional cost of motherboards, cpu's, ram, etc, then the cost of a bigger PSU probably puts you under budget for the same hashrate... So I guess I didn't think about it all the way through.

You are comparing stock voltage 390 with undervolted 480. Mine 390 are undervolted -100 to -150 with the stock clock and memory (they work for weeks without crashes but the exact undervolting depends on the model; I use Trixx utility). They consume 200-210 W from the wall measured by watmeter. The whole rig with 6 390's consumes 1300 W at the peaks.

[chronek]

Well, will we see 10.0 tonight?

We will propably get that after 0.04 zec wall, when miner farms will change to something else and they will no longer prevent claymore from release next version

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

currently the average is around 220 h/s

True.

I'm on 16.11.5 drivers, 1333mhz core clock, 2100 mem clock, with -30 mV undervolt. I get up to about 225-230 sol/s.

I'm on 16.11.5 drivers 1306 core clock, 1900 mem, -100mV 220-230 sol/s. (bios mem mod)

At that clock, even with the -100mV, you're using a ton of power. Less profitable than running stock speed or underclocked with less power.

[mamboOo]

Yes, that's right. My gpuz shows avg 80 - 90W

[jelin1984]

i had 4 cards
3 asus and 1 saphire
i mining
and after some minutes
saphire stop hashing'

how i can fix that?

rename your sapphire for asus ...

so, no log, no more info ?

[thedreamer]

Yes, that's right. My gpuz shows avg 80 - 90W

Which is like saying ".......I have Fast & Furious stickers on my car, so it has an extra 400HP....."

Useless..
Put a real kill-a-watt on it and see what it really uses. 80-90watts will NOT be getting you 220Sols/sec with a 1305Mh Overclocked core and 1900 RAM.

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

duude.. this is a typical newbie mistake. dont worry it happens.

you need cooler cables.

try to lookup "mining cables"... they will come in cooler colors, black is the worse ones. try to find ones with all white cables.

put a fan pointed right at your cables until you fix this problem!

unless you have the blue cables like me, they are watercooled. no fan needed.

I know a guy who tried the watercooled route just by soaking all his plugs in a slightly saline solution of water overnight to get some good marinating effect before plugging them in.

I would NOT recommend it.

[vltone]

Can someone guy me how to enumerate GPUs via OpenCL API to execute OpenCL code,
and also it has to enumerate GPUs via ADL API to manage temperature/clock.

thank you

Don't worry, you're both wrong.

With free power the only way to go is Fury. $260 for 315 sol/s out of the box on 15.12 drivers.  On 16.xx you can get ~350 sol/s with an undervolt and GPU overclock, but admittedly it is less stable.

Worried about power overhead? Buy a cheap server PSU dedicated to the cards.  Problem solved.

Edit: Even if power is a factor you can run Furys on 16.xx driver with an undervolt and underclock to get ~300 sol/s @ 150W.  That very nearly matches the efficiency of the RX series but nets 50% more hash for 25% more retail cost.

[br2459]

I am currently running on average 950H/s so here's hoping Claymore's newest version will get me to 1KH/s! I have 2 RX480's 8GB, 2 R9 270x's 4GB and 1 HD7970 3GB.

I will release new version in 1-2 days. Not all cards will get speedup, but at least Hawaii and Polaris will.

Tahiti and Pitcairn are maxed out?

I would hope not since my 7970 is Tahiti and my 270x's are Pitcarin. Although I am pushing 302H/s on 2 R9 270x's. Only 200H/s on the 7970 though.
