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

[shadabahmed]

from last 30 hours DWARFPOOL is doing great

[tutorialevideo]

Pair of Sapphire ref-style RX 470, no bios mod

1250/1750/-75mv

 -i 7

Went from a little under 200 sol/s each on v9.1 to 233ish each on v10

Nice improvement from 9.2 on my dual R9 280x too - 380ish total to 417 (unhappy card at -i4 happy card at -i6)

 1100/1500 no bios mod


 211-221 sol/s for a single R9 280x is in the range I'm seeing on my pair.

What memory do you have on your gpus?

[dragonchopper9]

v10.0:

- improved speed for most cards, up to 8% (depends on card model). About 340H/s on stock 390X, 255H/s on stock RX480, 320H/x on stock Nano.
- added "-a" option to select best algorithm implementation for your GPU.

PS. This is an intermediate version because I had no time to implement all optimizations I planned for this release, also I had no time for tests. In 1-3 days I will release another version with further speedup.

Today new version 

I do not understand why increase the speed yet?

I'm looking to pickup an RX 480 card and there is about a $100 difference between models, can anyone tell me if this card:

http://www.newegg.com/Product/Product.aspx?Item=N82E16814150774&Tpk=N82E16814150774

will work, of if there is a better bang for the buck? The XFX Radeon is almost $40 more here. I noticed some threads discussing reference boards, but I don't understand the meaning.

Sorry if my english is not great. thanks in advance.

Yes, they are great cards for the price, and very good for mining

Ok thanks for the quick reply! I just didn't want to buy one and then 5 minutes later someone goes, well if you only spent $10 you could have got XXX... :p

GPU hangs in opencl error
Is it possible that it is a RAMs fault ?
4gb RAM 6xRX480s
v9.2 works great

A reference card is made by the the chip manufacturer (AMD or Nvidia), and has the 'standard' PCB/cooler for a given GPU. Their partners (SAPPHIRE,MSI,EVGA,etc.) can make cards based on that reference model or make their own custom PCBs and/or coolers to go with a given GPU.

Reference cards tend to have blower-style coolers, while partner coolers are often open air-style, for whatever reason.Non-reference graphics cards have better cooling and better performance.Do not worry about the English. Not all users of the English-speaking world. Only they can perfectly know speak english. Sometimes neither they, because only God is perfect .

Damn, the increase speed is awesome but my rig is getting more and more heat and its summer here lol. Anyone did a comparison between mining zec and eth too see which one consume more energy?

I think both are nearly the same. It depends how much undervolting can take each algorithm. For me zcash is by a tiny bit less power consuming.
Currently here is a winter with -20 C outside. Inside it is +25 C because I have rigs in each room  . Excellent solution for heating the appartment  . But for the summer it is a hell. Two AC 1200 are not enough. I will need a third AC or have to figure out some way of channelling  the heat outside.

[malandante]

what is wrong with my 280X?

seems 280x beats rx 480 again? LOL!

What miner do you use?

omg, I cry. I don't believe what I'm reading here...

Yeah no idea how you get 290H/s. I am guessing your timings might be modded and its incorrectly displaying the hashrate. I had this happen before with ETH mining.

For Tahiti, the most I can get is 245H/s and that's with a high end 7970 which is maxed out at 1100/1575 with memory straps hacked. The other 280x are all at 230h/s, which is still higher than my RX 470s.

its stock rom, 1100 core 1500 mem

it started at about 230 h/s after mining for the dev fee it started to climb to 290 h/s

there is a problem because the rejects are pretty high.

as of now running time is 16:57, total shares 2054, rejects 242 ...i suppose it is still getting shares like a 230 h/s...and looking at dwafpool it is not far behind my 2x rx 480 rig in shares..

I had a similar issue with a 280x toxic, clocked at 1150/1600. I tried lowering clocks, raising voltage but the card was running wild to up to 320 h/s and a lot of rejects and errors. Lowering intensity to 4 solved it. For some reason, cards even within the same chipset behave differently.

[ofpcarnage]

I Get this on one o my RX480 cards it displays @ over 600h/s with lots of rejects I've tried intensity 4 with no luck.
It was fine up until v9.1 I think.
Since then I've not been able to mine for zec incase I damage my card.

What memory do you have on your gpus?

 Both the R9 280x and RX 470 cards I have are Hynix ram

[voidwalker]

Does anyone know if you can set gpu/memory clock directly from the miner in linux with amdgpu-pro ? What about undervolt in Linux ?
And why do my rx 480 rigs reset themselves in linux after a few minutes of mining, but the rx 470 work fine ? very strange.

Hello! Tell today will be a new release? The normal increase in speed ?

[Redcard]

Hello! Tell today will be a new release? The normal increase in speed ?

Will you ever stop asking for speed? And when you get more speed you'll get rich or what? The zec price is still LOW!

I do not understand why increase the speed yet?

because of optiminer improvements

[smaxz]

Anyone using 7970's. What are you finding for the best Algorithm? What hashrate are you seeing?

I'm getting about 890H/s with 4 7970's using a2 i8. With a single 7090 I get 223H/s with a2 i8.

Thanks

i am getting 175 with -a 1 -i 4 clocked 1000,1500. nofee 1.

its an old undervolted XFX left over from my scrypt mining days though and really on its last leg performance wise so not sure how much of an benchmark it should be considered as.

i think i'll be switching back to optminer soon for this card as when initiall tested it reported a bit under what claymore 10 shows.. but the average seemed to be creeping up on my pool stats for this mining instance.

 One of my pair of R9 280x (both are the SAME model of Gigabyte Windforce card) gets very wierd unstable and unhappy at anything over -i 4 but runs reliably at that intensity.
 The other one will run at anything up to -i 8 but seems to give the highest reliable hashrate results at -i 6.


 My RX 470s were happy at -i 8 on v9.1 but got very crashy on v9.2 at same settings, dropped them to -i 7 and they're a lot happier - then moved them to v10 and they're still happiest at -i 7.
 (definitely not an inadaquate PS - that machine is running on a Seasonic X-1250)

[Claymore]

I'm still working on new version, already got good improvements but still a lot of work is required. I plan to release an update in 1-2 days.
