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

[manoe]

my experience is as follows i bought 30 v.3 usb risers 10 of the are in current use another ten are in the recycling bin and the remainder are new for spares

I just bought a V3, solder is fucked up... Returning and buying the V6

Link to these risers?

This is where i bought mine from, they come from Texas (USA) so shipping is fast in the USA.

Also a good one mainly for the USA much faster for his shipments than the other one sometimes can last 15-30 days

My 480 rig loses ~170 sol/s at the pool, but my 470 rig reports very accurately without fluctuation. The Pitcairn cards are definitely very efficient for zcash, but I cannot explain the pool flucuations.

What Windows are you guys using? 7 or 10? Which one gives more H/s?

[denis1995]

Is ZEC more profitable than ETH?

not anymore, it's way lower, assuming a rig of 1000(6 x 480)sol versus the same rig that do 180MH it's 0.002 worst, conusmption is also higher i guess or on par

What bios/settings r u using to get 180MH from your rig? I have low power bios and have 170mh, on this 180mh was unstable. Is all fine on your rig?

The question you should be asking is, what is his hash per watt. You can crank up the speed but you exponentially use more power.

I have free electricity, so for me more important is MH/S

How free? Solar panel?

if you use risers here is what i have discovered they are crap

I haven't had an issue with them, maybe with another miner or the first few versions of claymore, but I see no difference. at least with powered USB risers.

I think latest v7 is pulling more thru the risers also we saw the user with fried mobo.  This can't be no coincidence. Maybe someone could run a ammeter on the 12 v supplying the riser?  Looks like the cards are exceeding the pcie limit.  I too in the last week have fried a riser after mining many months on eth

Rx 480 rig. Burnt riser was on xfx Reference card with +10% powlimit

Does anyone know which is stable downvolt  for SAPPHIRE RX480 NITRO OC + for 1342 MHZ GPU and 2000 MHZ for memory?

I'm ok with -100 mv

[dumpida]

@Claymore, in the share rejected display, can you also display which GPU's share is rejected? So that we can adjust the GPU accordingly.

I have a rig with 6 x sapphire nitro+ oc rx 480 8gb cards and using a modded bios from eth I am getting:
- 1000h/s for about 910w at the wall
Can we get more h/s from this gpu and less power draw?

I have the exact same cards, 7 of them in 1 rig.
1050H/s 780 Watts at the wall.

You need to underclock and undervolt.

I have now with modded bios from eth gpuclk 1150 memclk 2150, gpu core voltage -100mv
6 x rx480 - 930h/s - power draw at the wall 700w
If I try to lower gpu or mem clock I get hashrate drop

I use a modded bios(which I have posted) and 1125/2080 -100mv works well even with a monitor attached. About 152 sol/s but is only like 55 watts.

Hello,

Did anyone modded BIOS of R9 380 to rise the hashrate for ZEC? At his moment I use this modded BIOS: https://bitcointalk.org/index.php?topic=1620733.0 , which is good for ETH ( I get 23.8 MHS stable ), but on ZEC I just get about 125 H/s from 118 H/s with standart BIOS. I did not find any thread where someone did hack R9 380 BIOS to get high hashrate on ZEC. If anyone know, please point me. Thank You!

Hello
can i use this bios for asus r9 380 ??

What Windows are you guys using? 7 or 10? Which one gives more H/s?

Win 8.1

For more than 5 cards in 1 mobo you need to install Win 10.

@Xardas2014 mind to share again the modded bios?

Hello,

Can we use mining rig rentals on this miner ? : )

Thx

Hi

that is not correct ! I'am using Win 8.1 with 6 Cards ! Thats working with a driver patch !

Have a nice day

why is the config file changing to this? is the 4time this appens...

 -zpool eu1-zcash.flypool.org:3333 -zwal t1QBdF2yimDubPeg2BsWCme843GegCWWifK.msi1

There is someone using open ports to upload their own config file to have the miner work for them.  either use -mport 0 to stop this or -mport -3333 to make it view only if you really need to monitor the rigs

Whoever this person is they seem to have been getting decent payouts of 0.01 ZEC at flypool in time frames ranging from 30 mins to two hours.

It seems in next update I will make "-mport -3333" by default instead of current "-mport 3333", so miner will use "read-only" mode by default for remote management.

Thanks  i will change to -mport -xxxx

time for V8 Claymore!

yep, good idea, many are having the issue that some1 is changing the miner settings and stealing this way the hash power.....


BTW, a big thanks to your work, really appreciate it and gladly pay for your work 2,5% fee... hope it works well for you same as for us....
