Best GPU's to mine ZCASH with?

[QuintLeo]

~snip

Cost per hash AMD RX 480 are better than Nvidia for ZCash. With a memory strap bios mod I get ~315 H/s from my RX 480's at ~125 W each.

Ahh ! So they are not worthless!

Thank you! You saved my life !

 For perspective, my Gigabyte R9 280x pair was doing right at 600 sol/s (one a hair over 300, the other a hair under) last night when I was doing some testing after moving the rig they're in over to Linux (Windows did one of it's inexplainable no-reason crashes that borked the OS somehow and I didn't feel like fighting with it to fix it) - Claymore 12.4 intensity 6 or 7 I think, 1100/1250 on non-modded cards.

 Oddly enough, I could NEVER get the same identical hardware to work right on both cards with any Windows version of Claymore I tried - kept having to dump one card WAY down on clocks and intensity for it to work at all.

 Down side - they eat a LOT more power than the RX 480 does, though fine-tuning and some BIOS mods would help a lot.

 Up side - they can often be had VERY inexpensively (in my case, I'm sure they have already paid for themselves in the year or so I've already had them so "kinda" free).

I have a number of rigs.

6 x Sapphire RX480 = 1100W = 1800 hash
6 x 1070 = 1150W = 2700 hash

Just that the 1070 cost more but save a little bit of electricity in the long run

I have another rig 2 x 1070, 3 x 1080ti, 1 x 980ti = 1600W = 3600ish hash

No mods nothing. Everything stock with no overclocks

What model are your 1070, and are you undervolting at all to get 1150 watts?  Looking to build my own 6x 1070 rig.
Thx,

 Figuring 100 watts for the rest of the system, that would be 175 watts per 1070 - which is higher than the FE version's TDP and slightly less than the 180 watt TDP on my Gigabyte 1070s.
 No undervolt needed for those figures.

 450 sol/s is also in the ballpark of what I see on my Gigabytes when I let them run at 100% power limit - but I usually run them at 80-85 and tolerate losing a small amount of hash in favor of the greater efficiency and cooler running, especially the last couple of days when we had a heat wave here locally (I had 290s thermal limiting a bit due in part to the hot and due in part to the limited ventilation and cooling I can do in my current place).

Can some tell me if the price of a GTX-1080 is worth the extra cost from a GTX-1070? What hash rate can I expect and what are the power requirements when mining Z-Cash?  Any help is appreciated.

Only you can answer that question

A 1080 costs more but obviously hashes more

Do you have a limited budget?
What is the maximum number of cards you can run?
Do you care how fast ROI is?
How important is system/card density?
Do you care about maximum profits per day?
What are your power costs?
How much power in total can you draw?
How many GPU's are you aiming for in each rig?

For some people a 1060 3GB card is best, and for others a 1080ti is better even though it costs 3X as much

im a bit new in mining but i have a realy good friend who gives me A LOT of instructions

i have evga sc 1060 for gaming now (using this system on everything, setting and testing up miners etc)
and i have asus 1080ti fe too ...

now 1080ti is mining through skein algo DigiBytes with +-850MH/s or +-1200DGB/day (private miner, undervolged on 75% of tdp, +150core, -300 mems....with common ccminer i have +- 550MH/s) for a 230w total system power consumption (+-180w only vga)

and for ZEC:

i tested only ewbf miner (i think it has best results nad is strongly recomended)
1060 (70% tdp, +140 core, -300 mems, +-90w) +-285sols/s (realy quiet, in case)
EDITED: 1060 (75% tdp, +140 core, +400 mems, +-90w) +-305sol/s (didnt tested with 1080ti yet)
1080ti (70% tdp, +250 core, -300mems, +-180w) +-680sol/s but its very noisy to reduce temps :-D and system with this card will be minning rig ... but still dont know what to buy for a cards, maybe another 1 1080ti + 4x 1070 (have now mb with 3*pcie16 and 3*pcei1x) and 1200 p2 evga psu (i think this will be enough)

... there is not a problem with performance vs power consumption on any 1xxx or 4xx/5xx ... problem is with 24/7 load and possible lifetime reduction of vga compared to their prices ... and this applies specialy for 1080ti .... (IMHO - 1080 is out of mining, 1070 has better perform vs price just like 1080ti and their lowering prices)

whats your average return daily on that setup?
~500 usd a month w/ 1200 dgb a day? have any good links on skein / mining it?

[VoskCoin]

On the topic of the 1080 TI, is there anyone one of them in particular that are the best? for example

https://www.newegg.com/Product/Product.aspx?Item=N82E16814137115&cm_re=nvidia_1080_TI-_-14-137-115-_-Product
x is the best 1080 TI because of x y z

[bobben2]

Small rig with 2 x Asus R9 280X
320W total for rig.
580 sol/s
I have been regretting that I sold off my R9 280X Gigabytes, Sapphire Vapor-Xs, even my shitty XFX DD cards.
Only have these two Asuses left.  They are both well into their 4th mining year.

What is an average power draw for 1070? Should 1000w G3 EVGA be sufficient for 5 of these?

[QuintLeo]

My Gigabyte full-length 1070s have a TDP of 180 watts - which is the highest I've seen on a 1070, most seem to be at the "FE" level 155 watts TDP.

 A EVGA G2 1000 in a rig with a low-TDP CPU should handle 5 of them, and if you lower the TDP to under 160 watts (like most ZEC miners do) or use cards with a lower starting TDP (EVGA 1070 SC as an example) it should do so comfortably.

super jetstream can touch 225watt, i tested with my rig of six of them

Would you pls share your MSI afterburner OC settings to get it around 160w?

Thx a lot.

[QuintLeo]

as i said AT THE MOMENT OF WRITING , stongest card providing HIGHER HASH RATE (no matter the power consumption)  is RADEON PRO DUO ... 900 to 1100 hashes /s  depending on the oc you apply ... of course the higher the hash rates the more inefficient it is... at 900 hashes is a bit less efficient than nvidia cards (4.5 w for each hash)

 Out of production for at least a couple months, try FINDING one at all much less at a reasonable price.

 Nice if you CAN find one though.

 

 To crazyivan - I'm not the one with the MSI 1070 cards, mine are all Gigabyte or EVGA and at this time I don't worry about "optimise for sol/s" as I'm on a "fixed price for electric usage" lease.
 (That should change VERY shortly though).

I am going to buy new GPU for my gaming PC and looking forward to get GTX 1080 or 1080Ti. I already have AMD ETH rig.

My plan is making my gaming PC to mine whatever Nvidia card can mine (Zcash, Skein etc.) when I do not game/use it.

This means it will mine likely 20 hours a day. PSU is Seasonic X750-KM3.

I do not plan to use more than two GPUs as I will be using current system without buying any other hardware/upgrading. This is supposed to be gaming PC but why not mine some on it.

Actually my mobo (Asrock E3V5 Gaming) only supports Crossfire but no SLI so  dual Nvdia cards will make no good for me for gaming but only for mining.

One option for dual Nvdia GPU would be using one of them for gaming while the other one mines and both of them mining when I dont game.

Electricity cost 0.11-0.13 USD/Kwh.

I am more inclined to a single GTX 1080ti rather than dual GTX 1070/1080 considering no SLI support.

I think my Skylake Xeon 1260L v5 CPU will not bottleneck a 1080ti as I can OC it to stock i7 6700/7700 level easily as my passmark test result indicate.

If I invest 950-1000 USD local purchase (or 775-800 USD international purchase) for a 1080Ti now does it make sense for my conditons?

If yes which brand and model would you suggest to buy?

Can it ROI in 4-5 months or till the Volta GTX GTX 2070/2080 comes into market and kills it price and performance wise with current coins Nvida can dig?

High performance gaming will be a very good side benefit for me.

Thanks.

The GTX 1080 is the equivalent of 1.3X GTX 1070 in performance, and (here at last) you can have it at the same price ratio ( X 1.3 $)

This is the cheapest 1080Ti I can find too. Somebody wrote they are making 1080Tİ rig with Auros.

I wonder results for these cards as well.

[QuintLeo]

I'm not using any of the Gigabyte 1080 ti models, but the one you linked appears to be the 1080 ti version of the pair of 1080 cards I DO have.

 Should be reliable, and fairly cool, for a non-Aorus non-watercooled 1080ti.

 As a general rule, explicit SLI support by a motherboard isn't actually required to do SLI - that's more of a "yes, we tested it this way and certify the slots are positioned correctly to work" thing.
 On the other hand, SLI and Crossfire are going to be a dead issue in a few years, due to DirectX 12 support for asymmetric compute and multi-GPU support with no SLI or Crossfire needed.

 Your Xeon is serious overkill for a mining machine, mining doesn't need much CPU.

 Given the current pricing structure on the 1070/1080/1080ti they're all pretty close to a tossup as far as hash/$ goes at the system-build level on most coins.
 In theory, with your specified system and PS you should be able to use *2* of them eventually.

 Just don't try to stick an Aorus model (or any of the "2.5 slot" models) in a slot that doesn't leave it at least 1 slot worth of fan clearance to the next card over.
