Claymore's ZCash/BTG AMD GPU Miner v12.6 (Windows/Linux)

[GreenDogh]

I could downvolt eth only to use ~80w stock clocks, GPU-Z (not at wall, but same card so it's relevant).  ZEC uses similar.  If you downclock to say 1000MHz instead of 1260, you get same speed on Eth (zec suffers), but you can lower voltage another 100mv or more, chopping off perhaps another 20w (haven't tested yet).

Sure you can downvolt to that extreme but your hash per watt suffers past certain points.

Anyways, good luck doing that 2 times a day per card if you're using the RX series if you're wanting to mine whatever is the most profitable.

Just FYI, on my Sapphire 470 Nitro 4Gb, I'm hashing at 150-152H/s per card with a hex offset of -162.5mV undervolt. The whole system uses around or less than 400W @ Wall, all 4 cards give me a nice and stable 600H/s. I'm currently hashing with 3 rigs at 1800H/s for 1260W, so that's a ratio of ~0.7W/H

What I noticed, is that past -150mV, you gain very little watts.

Dude, I using Sapphire RX470 4GB (not Nitro) some modded memory timings, and one give me 170-172 H/s other 4x RIGS ~ 690 H/s.

Yes, but I doubt you'll achieve that hashrate with a -162.5mv undervolt . You're not mentioning your wattage @ Wall?

@Ursul0 yep, my electricity cost is quite high (I'm in Switzerland) so I'd rather hash a bit slower but use as little juice as possible. I've got some solar panels coming in though, 20x 300W panels

No undervolt, everything stock (volt, clock, memory speed), but maybe try tomorrow...

I thought this would be the best place to ask.

In the US where is the cheapest place to buy win 10. Is the 64 bit home edition good enough?

TIA

Buy WIN 10 x64 Prof serial on aliexpress (5-10$), install original microsoft image and run without problem many monts ago, activated/updated like original no activators needed and simply upgraded to anniversary edition.

Based on the power consumption of claymores miner, is it safe to say that a Corsair RM1000i can handle 3 RX 480's on powered risers?
Here is the power use with 2 RX 480's

Easily 5 cards. Undervolt with 6.

I feed 4 rx 480 with a corsair 750w ( gpu + risers)

You can count each card around 120 - 140 W

Ok so not that much different or more/less then the cards are rated for anyway, actually a good bit lower then i thought it would be for this miner.
I was thinking it had to be pushing 180 each or so. Thanks guys

You have a very good point there!  I am rephrasing:
Also, the assumption would be that there would not be dual mining with ETH, ETH only.  This includes using a dual miner in single mode.


What are the implications in the comparison of efficiency/functionality of the following Rigs:

A)  2 xfx R9 295X2 = ~$900 = ~1000W = 1120 SOLs ZEC;            ~___W = 120MHs ETH

B)  6 RX 470s = ~$1100 = ~880W = 1120 SOLs ZEC;                    ~920W = 164MHs ETH

C)  5 R9 390 = ~$1200 = ~800W = 1250 SOLs ZEC;                     ~___W =____MHs ETH

I think all of details / presumptions are correct.  This would lead me to believe, as it stands, that C would be the most efficient option...correct?

Even when not dual mining, ETH is still considerably higher than ZEC mining.

Anyways, when you factor in depreciation, resale value, age of the cards and future coins / support, I (personally) would choose the 470's.
Also keep in mind, 2gig cards can no longer mine ETH/ETC so their mining power is forced to go into ZEC (and 3gig cards later) so ZEC difficulty will continue to climb and become even more unprofitable.

But you are forgetting a very important parameter, no?

If ZEC price follows upwards then it will continue to be more profitable for as long as it goes up (or difficulty falling) and serves its purpose
That is to keep increasing the production of ZEC's in order to become a tradable currency that is difficult to manipulate

Sapphire 470 8GB (1750 strap)
Zec 1260/2000 -i 2 1020mv, 82w GPU-Z Avg, 177H/s
Eth 1075/2000       820mv,   58w GPU-Z Avg 27.5MH/s

You can control clocks and voltages with Claymore's miner easy.  Recently Zec and Eth similar profit on Polaris, and Zec is a lot better on 7000/200/300/Fury, so switching on 470 makes no sense.

@xeridea is it easier to control wattage through calymore than through wattmon?

Ive found with wattmon if i go below .96 volt or sometimes even 1.0 core voltage on any card with stock core i crash

You can set voltages and clocks on startup (see thread OP for details).  I don't do it because I don't change clocks, or switch coins often, but many others do.

How low you can go depends on the card.  For finding lowest voltage, it is better to go to wattman, and do a voltage drop based on stock.  Stock voltage can vary from 1050-1156mv, so results vary a lot.  I have found generally 960-1030 is lowest stable at stock clocks.

After you find lowest voltage for each card via wattman, you can set the voltages on miner startup if you switch coins, for winter/summer, etc. Just make sure to get card indexes in right order (-di option can help), or volt all according to the worst card).

Dwarfpool cheating a bit. 
Anytime when you open http://dwarfpool.com/zec page, you'll see in "Last 50 found blocks" that pool found new block with 1-5 minutes back.

But if you reopen this page after 15-20 mins, you''ll se that no block found at that time.

and

[boysie]

are you working on proper support for the RX 480 cards? currently they get 33% less than the 390s in zcash but only 5% less in ETH/ETC

Dwarf might be cheating, I really don't know. But I believe you are misinterpreting the info they provide.

The block listed as "2 minutes ago..." is the one currently being mined. And dwarf very seldom is the pool to actually find the block. Therefore, when you open the page after 20 min, you'll see a similar "4 minutes ago..." for another block currently being mined and probably the previous blocks were found by another pool.

Got it?

Every algorithm hashes at different rates with different cards.

390s is just better at hashing then the 480.

Speeds are normal. You are comparing Apples to Oranges.

Hey Claymore, we did have a vote, and turns out people do want to see what you've got in stock for us !  After next version, you can go to Bora Bora you deserve it

Looks like someone released a fake 9.0 beta version. I posted a warning in the comments to only trust this thread for new releases, but it was removed. Here is the link to the youtube video.

Btw, I can't undervolt in Trixx or AB. Is that because I'm using driver 16.11.x? The voltage setting is locked.

Trixx doesn't let you undervolt 295x2 but AB does. You sure you checked all those basic amd settings in AB? But with AB you are stuck on -100mV when you actually want to go much lower. This is where you need some basic hawaii bios modding.

Yep, checked everything in AB. Using 4.3.0 Beta 14. The Core Voltage (mV) setting is locked when the 295 is selected, but unlocked/usable when the 470 is selected. I might try undervolting in the Claymore command line. Or maybe not (free electricity ).

After much hype and many friends asking me to try out Optiminer; I recently tried Optiminer for Windows v0.6 on my test rig.... but found it no better than Claymore V8.

I maybe wrong and didn't test in detail because I use my 7x370 test rig just for short while but I see many negatives in using Optiminer - including losing the monitoring aspects of Ethman, excellent controls of temperature management, GPU core & memory settings, etc. etc. in which to me are the REAL hidden gem of ALL Claymore miners, on top of the raw blazing speed.

IMHO, Claymore need to unleash v9 (Windows and Linux) and claim who is real king of the hill BECAUSE Optiminer now released his latest version also on Windows. While I begin to understand Claymore's position with SilentArmy issue in v1.1, since Optiminer now has come into the Windows with v0.6 ... I think Claymore v9 (Windows and Linux) is justified.

With all this chatter of a successful hardfork and "state clearing"; ETH going POS soon last night*, ZEC stabilizing at the $60s range, XMR went crazy overnight, ZEC (and XMR) mining use LESS power than ETH mining, the answer is clear..... v9 (ZEC) and v10 (XMR)  

What say you Mr Claymore?

Optiminer is no longer available, so Claymore is still king.

[Marvell1]

anyone seen this strange issue ?  After i flash a card sometimes with atiflash it shows

0 GPU clock and 0 Mem clock above my new flashed values in GPU-z

I've seen this issue before and fixed it sometimes by removing and replacing the card , howeever this time
when i replace the card I see the same thing. 

Ok now it gets really strange, if i pull that card from the rig, another card in a totally different slot shows the same issue
until i replace the card.

this is windows 10 btw, anyone seen and wierdness like this ? My next step i guess is to re-intstall drivers.
