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

[Claymore]

ZEC has complex PoW which consists of many steps, they are different and therefore have different power usage.
If your PSU cannot handle power usage peaks, it's not a problem of the miner.
Also note that I try to achieve maximal speed, it always causes more power usage and more GPU usage, so if you have OCed GPUs or weak PSU it may work for v8 but may fail for v9.
BTW, I added a couple of additional range checks for better stability (these checks are non-critical, just for sure), I will release an update in a few hours. Note this update will not change power usage.

If I was able to get 5x470 oced working on a 750w psu at 1065h/s (claymore v9), which previously at stock settings would just shut down, then you can too.

By the same note, just because you did, doesn't mean everyone else (queue Jeremy Clarkson voice) "in the world" should have to jump through hoops.

v8 == no changes required. Works.
v9 == same configuration as v8. changes required. Doesn't work "out of the box" or even "on stock".

Well, again, the fault belongs to the manufacturer, so Claymore can bear no blame.
And you not wanting to tinker with your systems to make it work, is your own choice. It is not something that everybody has/wants to do.
If you have not realised yet, you are in the bitcoin farming business, where if you don't stay competitive by all means, you don't win that much. Complaining only doesn't get you anything.

well the spike its weird ,its jump to the roof,
after reinstall driver & checking the rig, 6 hrs past without shutdown, hope its going well

[Gambler8899]

great, thumbs up

[sirlordcomic]

some of my rigs reverted back to v8.

v9 has some serious stability issues that needs to be adressed.

Check clocks, volts, and PSUs.  I haven't had a single crash on 24 cards (470/480).  I have moderate undervolt and have PSUs at ~70% load.

So you think with so many people complaining about v9 load spikes that everyone is having hardware problems?
The more likely answer is that v9 has a stability issues as v8 works perfectly fine for everyone.

Agreed. Waiting for "9.1". I've read the arguments, but this is not a stable miner.

i'm quoting this..

i guess a lot of miners today didn't start mining during scrypt mining era (ex. litecoin) ... most likely they started mining during ETH era where GPUs don't draw their max rated power.

my rigs are all stable btw, i just reduced the core clocks of some of my overclocked GPUs and all is good again.

perfect. thats what i like, software made to wring every ounce of performance from hardware.

if someones setup (OC/timings/voltage tweaks etc) or hardware (PSU, cables, whatever) are substandard then they need to fix it, not have you waste time coding your software to baby stuff.

people always have the option to run previous versions.

myself, i had to up the voltage slightly to my 390s to get stable on v9

Miner is stable, your hardware isn't. I have isolated the culprit card in my restarting rig and managed to make it run stable with v9. Now It hashes a little lower then the rest of my cards and still higher than v8.
Sure you have to look into what's happening in your rig, it doesn't work stable out of the box like v8 if you have weak components. Increased hashrate comes at a cost.

Finally, some down-to-earth users around here...

Claymore should not mind peoples who do not know how to power their cards,
My rx480 cards can be powered 400W each safely (i even build own modular cables), my rig can work stable till 2,5kW (now using 760W), i am prepared for any algo with overclocking

ppl who complain about the spike, they really know exactly,
the spike its weird , its hit maximum gpu can absorb
my rig use only 860watt psu can handle 6 gpu (5 RX + 1 Nano) its consume 740 watt total,
heavy undervolted & underclocked,

[mettalmag]

Can you guys please explain what are the benefits of mining under SSL connection directly to pool ?

400W per card ? I use 750w PSUs on 3x GPU rigs all of them are RX480 8G and modded with low power bios for ETH. Total I was getting 333Watts from the wall on V8 and 345Watts from the wall on V9. (no clocks no mems changed, 185h/s per card)

[thedreamer]

Dunno what the fuss is about.

I updated to v9 right after it came out, going from v8 on all my rigs and there have been ZERO issues. A little more power use and spikes up about 40-50watts on the 5-6 GPU rigs, but nothing that can not be handled.

I run my own BIoS on XFX based hardware and it's been stable since v9 came out, without any crashes etc..
I always say, check your hardware first as more than likely it's a power supply, cable or motherboard issue.
Just because the v9 taxes your whole system more and IT can not handle it, doesn't mean it's bad.

My r9-3xx/2xx GPU's added about 12-18% in hash rate, and the RX based GPU's about 4-5%.

Sadly with the price of ZEC, I might have to switch back to ETH soon.

[rozsada]

@rozsada try the 16.9 drivers. How many watts is your PSU?

@mettalmag yes, dwarfpool is paying me roughly the same as Claymore miner says

Which one 16.9.1 or 16.9.2?
On my Power block is writen the next:
1300W max
+12V 106A max
-12V 1.0A max
+3,3Vsb 7.0A max
(is it required info?)

6x r9 390 - 1736 sol =)

Will this update give more speed  ?

[chronek]

400W per card ?

If i play games it take 360W, if i overclock it can get 400W, just because zec using 100W it not means that other algo will not use up to 400W, zec and eth will end soon and will you be able mine other algos?

ZEC is a second life for my old 280x cards. ETH is for my new RX

And about the fuss - electronics components do age, manufacturers use barely passing QA components, etc....

In my last batch of RX cards it was a miracle to find a card capable of doing 2100 memory on eth.  Tested v9 on them and i had to reduce memory clock to default 2000 otherwise rig rebooted.
My old 280x cards were running 1625 mem clock on ETH mining. They could mine ZEC with those settings with initial Claymore releases but with version 8 I had to set memory to default 1500 on all of them. With v9 I had to reduce 1 card to 1400 MHz for stable mining.

Blaming "power spikes" is easy. More important is having discussion about the real causes and how to overcome them.

It's a bit strange, I'm running  claymore's zec v9.0 without any problems ( I have the same cards)  It could be a PSU issue
