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

[Q_R_V]

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

Around 200h/s per card, 6 cards in rig, below 800W.

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.

As a thank you to all the actual farmers that supported my mod, i've lowered the price for 0% fee Claymore ZEC Miner + ETH Dual Miner, and have thrown in his other miners including the linux version!

thanks for your advise.that was very useful for me.

"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.

Thats true only if you have very good PSU's...

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.

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!

What did you do to your cards???

I have 2x 7950 @ 165 sol each

I have 2x 7990 @ 200 sol per core

What can I to improve my hash rate, is it memory timings?

 Hash rate improves 10/20% if I put intensity above 1 but it will crash very soon after - same on all cards

Thanks

Intensity, timings and overclocking.
Probably you have too little power to run all what you have with high intensity. It may be PSU, cables or risers that are not good enough or even just some bad contacts. If you increase intensity, then power spikes will grow too. With highest intensity spikes can be 2x above avg. Try running only GPU0 with high intensity and see if it is stable. If yes, then GPU0 and GPU1 and so on. Then you will see how much you are missing to run all of them with high intensity. And to ease your need for power undervolt your cards. It helps too against spikes unless you go too low.

[orbital_station1]

Noob question, but how to under/over volt cards?
Do I write eg. 1100 (mV)  or -50 (mV).
Can you give me and example?
Also what value to set? My MSI & sapphire R9 390 show approx.  1100 to 1150 mV on afterburner.

Btw current config:
MSI R9 390 1110/1500, ~290 sol @ 76 deg
Sapphire 390 1100/1500,  ~290 sol @ 78 deg

Is there room for improvment?
Thx, sry for noob question

Claymore keep up the good work mate!

No. Because 500+ Sol extra on a machine with no running cost is worth adding a $100 PSU

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.

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?
