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

[Yerba]

how i can make at the wall ?

With a wattmeter (kill-a-watt or other model)

Or with corsair I series ( corsair link ) PSU. Tested rm1000i with killawatt and rm1000i graphs were precise.

changed to dwarf, but have an "basic" question...

Main-Port (vardiff): 3333
Stratum-Port (diff=8): 3334 for CPU
Stratum-Port (diff=128): 3335 for videocards
Stratum-Port (diff=512): 3336 for rigs
Stratum-Port (diff=1024): 3337 for big rigs


what is the difference exactly in this settings?  i choosed the 3336 port as i have 3+GPU rigs, but not really sure about it... Can some1 explain me please?

Thanks in advanced....

Let it adjust automagically : use 3333 (better use auto when you're unsure)

On vardiff port difficulty grow and grow and grow...

And stops to grow when it's satisfying.
When you choose a static diff port you can have problems : too low difficulty and you will overload the pool with tons of shares (and waste bandwidth), too high difficulty and you will send too few shares due to the short duration of block (and loose a lot of hashrate because you work will be dropped before you submit a solution due to block change)

Every share sent is weighted by the pool with the difficulty of the share. Sending a lot of low difficulty shares won't earn you anything more than sending 4 times less shares with 4 times more difficulty

ok its sett on 3333, dont wana risk anything.... lets see how it works. But thanks for explaining me the basic, how it works in general...

That's a wise choice. You're welcome.

And with mining software getting higher and higher hashrate, it's safer. Static diff ports are often a trap. What may work well with claymore v4 may not work that well with v8 (hashrate doubled).

You may consider fixed diff ports when the miner is "mature" (no 20% increase in each release )

Any miners using claymore v8 on an Sapphire rX-470 - Nitro edition - 8Gb Oc that are undervolting to get the best possible hash per watt ratio?
If so, would you mind telling me you stats (at the wall please, no hwinfo/gpuz figures).

how i can make at the wall ?
hwinfo and gpuz give me 70W.

i use :
https://anorak.tech/t/anoraks-vbios-collection-optimized-settings-for-performance-power-saving/13/3

this rom with powersave :
https://anorak.tech/uploads/default/original/1X/ba97e4fa5363c3fbd9373b5f3480ce4d27a2fac1.rom
on Trixxx i make :
GPU Clock : 1126 (default value)
Memory Clock : 2000 (default value)
Power Limit : -5%
GPU Voltage : -100mV

What is your hash rate?

So, I've done some testing with my reboot issue, and i've found that if i leave the one GPU (GPU 1(the second one out of two in the rig)) running without running the first, that it works with no issues on auto fans.

The one with the shut down issue has blue print on the caps VER006.
The other riser has red print on the caps (instead of blue) and works fine.

I've nailed it down to the riser. It's defective or something like that.

Anyone else have this issue with blue print on the caps VER006 risers?

Recap on my issue: the rig would totally shut down if i left the GPU fans on auto, but if i put them at around 60%, they would work fine.

I guess i gotta put it all back together and all for now, and I'll contact the eBay seller and hope to get it replaced.

7950 - 170 h/s/ Good job

Go mine on Dwarfpool!!! No stealing shares  like other pools..... I switched from flypool to dwarfpool, and I have 15% more shares!!!(my real shares)

Interesting probbaly will make the switch if things dont improve on nano and flypool

I was mining on flypool for the past month and last night I switched to Dwarfpool for the night
I made HALF of what I was making in flypool
Back to flypool....

flypool is PPLNS payment format -- so you need to be in flypool for period of time to get maximum hash/reward.

is Dwarfpool PPS or PPLNS?

if Dwarfpool is PPLNS like flypool, then to compare fairly you need to be mining at Dwarf longer than a night...

Sorry for untopic question , but im wondering for a long time. I know that continious mining on one pool maximize the reward , but should it be uninterruptable connection to the pool ? , I mean does reconect lower the reward or not ?

Wow, It's very fantastic. This rig is suitable for your miner software

No, it's a false positive.

yep, it is showing like a virus when I'm pushing start.bat

[David Spuria]

Good to know! Thanks man

I don't trust Kaspersky but neither Zecminer64.exe seems legit,
why not to check it with other antivirus ?
or even with malwarebytes ?


Is there any chance to make miner mine on two pools like Claymore takes his DEV fee by mining for himself ?
I mean to make miner mine like 3 minutes every hour for other worker ?

Every share sent is weighted by the pool with the difficulty of the share. Sending a lot of low difficulty shares won't earn you anything more than sending 4 times less shares with 4 times more difficulty

There is a case where you may want low difficulty shares. If you have bad internet connection where an established connection may be lost, you may lose share because when you send it, it will not be delivered (in time or at all). In that case a share that costs a lot may be worse case than few low cost shares. Of course, TCP should guarantee the delivery, but in real life you still may have "connection lost" reports. So not being a recommendation, this could be a reason for static difficulty port.

I've read a lot of people have flashed their RX 480s with the 1500 timings to increase Sols/s. I have the 8GB Ref versions. Would this work on my cards, and if so, could someone point me in the direction of a tutorial? Thanks!

maybe this would help:

If I may recommend, don't flash your vbios directly with any downloaded vbios rom file.. instead make backup of your vbios, save it.. open both the downloaded vbios rom file and your backup vbios file with bios editor.. compare the values in them, if you like it, copy the values from downloaded vbios rom to your backup rom file.. save your edited backup rom file.. then flash your card with your edited backup vbios file..

My Kaspersky is not detecting it as a virus. Try uploading the file to https://www.virustotal.com/

Where did you download it from? The official links are at the start of the page.

Hi! Read this, maybe try to download it again from official links. If still detected as positive by your antivirus, choose to trust Claymore and use his miner or dont.

KNOWN ISSUES:
- Windows 10 Defender recognizes miner as a virus, some antiviruses do the same. Miner is not a virus, add it to Defender exceptions.
  I write miners since 2014. Most of them are recognized as viruses by some paranoid antiviruses, perhaps because I pack my miners to protect them from disassembling, perhaps because some people include them into their botnets, or perhaps these antiviruses are not good, I don't know. For these years, a lot of people used my miners and nobody confirmed that my miner stole anything or did something bad.
  Note that I can guarantee clean binaries only for official links in my posts on this forum (bitcointalk). If you downloaded miner from some other link - it really can be a virus.
  However, my miners are closed-source so I cannot prove that they are not viruses. If you think that I write viruses instead of good miners - do not use this miner, or at least use it on systems without any valuable data.

I see some posts that V8 reached hardware limits and there is no way to improve speed anymore. It's not true.
I'm working on new version with another good speedup, though it takes more time and efforts.

Maybe a little bit to early for the F5      

Already looking forward to it 

Great work!
