why devfee share more ? Embarrassed

Added to FAQ on first page:

Q: Why do I see more shares for devfee than in my mining for the same time?
A: Most pools support variable diff, they change "target share" after some time after connection. For example, you have very powerful rig, after connection you will send shares very often. It takes some CPU time to check your shares so after some time pool will send higher share target and miner will send less shares (but they will have more value). When pool updates share target you will see "Pool sets new share target" line in the miner. This way pool can adjust the number of shares that miner sends and balance its load.
So check the log or console text to see current target for main mining thread and for devfee thread. For example:
DevFee: Pool sets new share target: 0x0083126e (diff: 500H) - this is for devfee mining connection
Pool sets new share target: 0x0024fa4f (diff: 1772H) - this is for main mining connection
As you can see, target share for main mining is higher in about 3.5 times, so for main mining miner sends in 3 times less shares (but they have 3x more value) than for devfee mining.

any news about Nvidia support?

I will not release NVidia support. Neither Linux update. Please use mrb's miner for that OS and hardware.

peeps can anyone tell the solve rate of asus 4gb rx 470 with high intensity mode -i 2 ?

Unlock it in the bios, get an Athlon dual core.
Raises temps by 10c+ and will slightly raise the GPUs temps above it, but well worth it.
I used old stock fx coolers on mine after I unlocked them.

 Only works on SOME Sempron 145s, some the second core is in fact broken and disabled entirely in the chip.

 Worth trying though.


 There's plenty of cheap upgrade options for that socket.



 What killed the "value" of ZCash is that it's got pretty much ZERO adoption in place by the folks that matter - the REAL market - places like Newegg and such that take Bitcoin.
 ZCash, like almost all other altcoins, won't be worth SQUAT in the long run if it never gets adopted as a worthwhile coin OUTSIDE the cryptocoin mining industry itself.

I have G1820 cpus in most of my rigs, all running -i 2 with 0 rejects

Never had virus warnings like i get with this miner?
Is it because the auto inbuilt tax it takes?

face with problem on one my rig: 5*7870 cards.
with -i 2 got:
OpenCL error 0 #101 - -61 for all cards, and after some seconds rig hangs...

Anyone getting crazy 20% rejections on some of their rigs?

Its mostly on my Celerons but CPU usage is only 50% still. i3 seems fine

Yes. On my seven 290x rig with Celeron 1840 I get lots of rejects with -i 2.

I could only test -i 2 with one card anyway. So I tested -i 0,0,0,0,0,2,0

Using -i 0 across all the cards for now as -i 1 also gave me a handful of rejects.

Shame though, the 290x with -i 2 was peaking as high as 68 sol/s Sad

one of my 280x rig won't start mining with "-i 2", just 0 h/s and on and on .. "-i 0" and "-i 1" works

found the culprit, the 280x rig that won't do "-i 2"

the cpu utilization is at 70% already at -i 1

funny, the older cpu in other rigs, xeon x3220 (same as q6600) can do "-i 2" at ~ 50% cpu utilization.

this 2.1 version does takes its toll in cpu's

Damn Semprons, should of got some FX instead during the Litecoin boom

you should find cheap and second hand AMD cpu's that are at least better than my core 2 quads.

My Reference 480 8GB cards with strap mod do 55-57s/s with -i 2

nice, how about watt on the wall? worthed??
I checked a rig today that is already connected to a wattmeter. The problem is that i have a wifi repeater and a switch on the same circuit.
System + 3 x 480 + repeater and switch pull 460w from the wall

System ~75w
Repeater ~20w ?
Switch: 20w ?

So it should be around 115w per gpu.
I dont want to mess around with the rigs right now to meassure more correctly.

My Reference 480 8GB cards with strap mod do 55-57s/s with -i 2

I can check powerdraw tomorrow

Nice speed zilla, care to share the strap use for this? TIA
All that is done in the bios is copying the 1500 strap to 1625, 1750 and 2000 strap.

I have done that on all my RX cards:

Reference 480 8GB
Reference 470 4Gb

Slightly slower atm. I have my bats restart claymore once per hour

Hi Claymore
I am getting blow error repeatedly on ver 2.1 with " -i 2"

"GPU returned incorrect data! ....."

but it does not specify which GPU !
where is problem

Claymore miner has killed the value of zcash .   Cry

Better than the botnets taking that crown.

Its the price of the coin that killed the profit mostly, too much supply and too few buys.

and I agree the botnets don't deserve 1 single penny, I wish this was a gpu coin so we could eliminate the botnets from the hashrate.

There is a rather amusing flaw in Claymore's miners. With a small script you can vastly affect the devfee. If you have a script look at the log file to detect certain events, it can then trigger other events. So let's say your script searches for devfee mining start and adjusts your core and mem timing, then when the script sees devfee mining stop, your script then reverts the core and mem, it doesn't mine very much to the devfee address. It works with all his miners I've tested so far. A rather small but potentially expensive flaw.
