Does anyone know what causes the

warning ?

Lower intensity, remove overclock, and possibly use the '-old 1' command to drop back to 12.0.

GPU0/1/2/3/4/5: 380/290x/290/290/290
Command: ./zecminer64 -zpool eu1-zcash.flypool.org:3333 -zwal xx.xx -zpsw x -tt 60,90,90,90,90,90 -tstop 96,96,96,96,96,96 -powlim 0,-10,-10,-10,-10,0 -r -1

I'm running the miner (v.1.1) since today and noticed the following. At the start it runs fine, but after an half hour or so the zecminer64 process is taking 99% cpu load.

Also, bind errors (notice GPU0 jumping to 0 sometimes btw):

Any clues?

This is what happening to me. Its always the last card. So If I run all 7 it says GPU6 and If i start it with 6 diabled it does with with GPU5

First I would keep those temps under 70C. Second what GPUs are you using to give so little hashes?

This was not my data, I am getting the exact same thing tho. I have 7 x rx470 MSI gaming x. custom 1625 strap, 1180c, 2025 memory, -50mV

[WhyMe]

Does anyone know what causes the
"GPU #0 returns incorrect data" 
warning ?

In my case, was memory OC too high.

[dooferorg]

Tried this and not having much luck at all. I have 4 x ASUS RX 470s . Windows 10, Using 16.12.2 drivers. 8GB system RAM, 20GB virtual set. On a SSD

Underclocking the core seems to drop the hashrate. I have between ~265 to ~280 on each card currently.

-i 7
-tt 0
-powlim 7
-mclock 1800
-mvddc 995
-cvddc 1050


Temperatures are 71C on the hottest card with around 70% fan. I tried raising the memory clock up but ended up with errors. The cards are in an open frame and the power supply is one of those 1200W server ones wired with PCIe connectors myself.

Any hints?

For the Claymore Miner v 12.4 using 4 Sapphire RX470 Nitro 4GB, I am using this bat:  

ZECMiner64.exe -zpool ssl://zec.supernova.cc:2242 -zwal username.worker -zpsw password -i 7

Im only getting about .15 zcash every 25-26 hours

What can I do to improve performance?  Miner speeds read 276 - 288, Driver date 3-16-17 version 21.19.525.258.

What tool are you using to tune(OC/UV) your cards?

for a quick workaround if I'm starting from a fresh driver install I reduce CPU Freq by ~13-17% and then undervolt your top 2 clocks to ~940. So, it'd be around 1020 @ 940, duplicate the second highest rate to the same, then go back through all the voltages and just duplicate 940 until you reach an actual value that has been automatically tuned down to roughly the same voltage and then just save that.

so..

-asm 1 / works well for my Strix 470, however my Nitro+ 480 seems to work better when set via -a 0
-tt 0 / if you are setting your fan temps in Wattman or other Software
-i 4,5,9 - test out how the speed differs between -i 5 and your current -i 7. I get better RX480 speeds using -i 5/-i 6 than -i 7/8/9. -i 7 is usually good for the 470 tho.


-> -12.5% CPU Frequency -> Manual Voltage -> reduce down to at least 990 or lower.

-> Memory Clock -> Increase to 1900 -> Undervolt to 960.

-> Give all cards some Additional Power if possible, it keeps the RX470's from becoming 'complacent' when finding shares.

I run that kind of configuration on my Strix 470 and I hash at 300 with -i 7 and -asm 1...

HOWEVER - these are only a few things that work for me, running 1x RX470 along side 2x nvidia cards and an RX480, so I found the Undervolting kept the 470 under 55 degrees C while hashing @ 290-300.

You might just want to cranking up the memory frequency and core frequency and just cutting down the Core voltages by 100 or so.. then get the fans running fast.. Shit, I dunno - you're pretty much bottlenecked by how well the 470/AMD drivers interact with the equihash algorithm - so experiment then just wait for Software updates.

"GPU #0 returns incorrect data"

Lower the clock.

a sick gpu can also cause it. very high temps can also cause it in particular the vrm temperature that unfortunately is not reported by all cards

Guys, do you want ZEC to rise? If you do, why you put 40-50-60 btc sell walls on poloniex during pumps? Do you really think that your lazy trading will bring you profit? Place small bids several times during the pump if you are so eager to sell at that price. Thank you!

Can you elaborate this? How this will help? I don't have much BTC but I want ZEC to rise.

My solution to the issue is to mine and hold 1 Zec, Sell the next, Hold the next, Sell the next. Etc..  A way to build up your holdings for it just in case it ever skyrockets but still puts some money back into whatever you want to spend it on.

What speed are you guys getting with a R390x on the current version claymore miner ? And how much power does it consume?

Doubtful it is the miners, as most who are going to sell, sell small amounts daily and not accumulate 40-60 BCT worth of ZEC to just to place a sell wall as you describe a few pennies higher than the market rate. Much more likely the action of speculators and/or whales trying to manipulate the price.

Is there an option to show power consumption of individual GPU?

Not in the software.

So is there a way for miners to help raise ZEC?

I tried on Tahiti and Pitcarin cards miner versions 12.3 and 12.4. Speed is 2-3% more on 12.4, but 12.3 and 12.4 not stable neither lowing intansity not using an "-old 1" option. Different versions of drivers not stabilize 12.3 and 12.4 miners too.
Version 12.2 is the most stable version for GCN1 cards with any intansity or drivers, but slower than 12.4 version.

Claymore, would you make a new version with speed of 12.4 and stability of 12.2?

[Muddybit]

will a 600W PSU be enough for a Kaby Lake rig running 2 x RX480 (Sapphire Nitro 8GB)?  

A Kaby Lake CPU has a TDP between 4.5W and 91W, so not much information in here.

But never mind, for 2x480 a 600W PSU should be a good choice. Not very high costs, proper reserves and good load point for high efficiency during normal operation.

Thanks.  CPU is a core i7 7700.  Good to know re: PSU.

[sikkan]

My rigg is getting near completion

One 7990 and one R9 280, dual PSUs and a slight OC on the R9-card makes me reach 780 sols/s. I have to keep temps safe too (below 70c). Will probably be able to reach 800 sols/s when my PCI-e riser arives. Then I can put my 7990 card on the side and OC some more

I love hobby-mining

So is there a way for miners to help raise ZEC?

If Zec makes 5-6% there is every chance  the pump will gain speed and reach 20-50 and even 100%. It is a pity that all pumps ended too early because of 1-2 noobs that put sell walls. The moment they put 20 and more btc the pump stops, because the traders see that there is no way this wall will be eaten provided that the 24hr volume is so small and the usual trades are around 1-2 btc max. Of course the bid will never be filled so the noob gets no profit at all but he damages the profits of the whole community.

sometimes the walls are put up by traders to scare noobs into selling :-) That's a very common technique market makers do all the time on wall street. They do both fake sells and fake buys depending on where they want the market to go
