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

[muchoman]

9.2 is slower on 280x

Yes I see a small drop on this card (about 1%). It seems finally I have to add an option to select best algorithm (I already mentioned about it, but managed to postpone it), right now you can use v9.1 for this card. For all other cards I have I don't see any problems.

Thank you anyway, great work as always!

Radeon rx 470 g1 gaming 4G, ~1270/1810, timings, claymore 9.2, i8: 229 H/s average per card, +6%

[Claymore]

Another news: due to a lot of requests I got, finally I reconsidered my plans about Linux version, I will release it in a couple of days.

[Etolay]

Im getting 277 h/s with my RX 470 8gb.

One of my 290s is doing 290 h/s but the other does 220 h/s. Will need to investigate that.

Thanks claymore.

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.

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.

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.

Sure,
but 390/390x is exceptionally close and perform roughly the same with the right mods.

Good work man.. Claymore now please look into getting
Cryptnote GPU miner optimized for RX series of cards. IT has not been updated since ages
Thanx

[mistercashking]

Another news: due to a lot of requests I got, finally I reconsidered my plans about Linux version, I will release it in a couple of days.

Yes! Can finally go back to Ubuntu looking forward to it.

Thanks claymore.

280 hash on 470. Yeah, sounds likely.

Yes, he has already stated he will get to it when he finishes up a few things. Looking forward to the update and a Linux version of it as well.

[Claymore]

NOTE: v9.2 can be a bit slower (by 1-2%) than v9.1 on some cards!
In next update I will add "-a" option to select best algorithm for your GPUs (or I'll implement other workaround), right now you can use v9.1 for such cards.

[vectisitch]

across my rigs i have 1x280, 3x 290x and 7 x 290. i am now getting 2928 sols , so up 206 extra sols with v 9.2. thankyou. like adding another card

forget about fury, nano 270 sol at 90-95 watt

Fury's can do better than that and I am not sure if those Nano numbers would work on a farm with a ton of them.  I run my Fury's (more than 40) and 2 of my friends are using my rom and combined they have another 60 and we get 310 at 100-110w at the wall and it is stable on >100 Fury's.  I also have some Fury ROM's  that will do 290+ at under 100w.  

Cheers

btw- Free Power doesn't mean much if it is only a 20amp breaker, if you have 800amp of free power then that is different.  Lastly-- 390's are a poor choice because I am certain that person is limited to X amount of power and I know that I can fit WAY more hash in X amount of power than you ever could with 390/390x's

True, but operating under the assumption that he has enough free power to run the rig he's wanting to build independently of power draw 390s aren't a bad choice. All other things considered I agree.

Oh great. Thanx for letting me know !

Is anyone seeing a lower performance on 7950 with 9.2 compared to 9.1
I am noticing like 4-5H/s lower speeds...

[chafer99]

R380 v9.2 - 160H/s,  v9.1 - 150H/s
R370 the same as v.9.1 (130H/s)

[MrJaekin]

Im getting 277 h/s with my RX 470 8gb.

One of my 290s is doing 290 h/s but the other does 220 h/s. Will need to investigate that.

Thanks claymore.

WOW!  290 Sols/s on a 290?  Is this a ref model?  What clocks are you using?  I can't get more than 260 out of mine.

[vapourminer]

NOTE: v9.2 can be a bit slower (by 1-2%) than v9.1 on some cards!

my 390s got 5% or so boost. the 380 and 470, about 1%. 

every little bit helps

[Zetminster]

For R9 390, it is 7% faster, 2% more power consumption.

[fmz89]

rx up 6%, fury 5%
power consumption jump 1%
