Why might 1 of my cards be rejecting more than the others?
No HW errors, no GF or RF.

You are running a much higher intensity on that card, causing higher temps.
probably too high.

Yeah the other cards are 280x's

That one is a 290 so 83c for that card is actually pretty cool.

I probably should have mentioned this in the previous post lol.

Yep, try a lower intensity, play with TC

[Anubite]

You could also try setting custom intensities for each card, separated by commas (-I 13,13,19,20). You can also use commas on other settings. I don't know the max temp of 280s, but I do know 290s cards can take up to 94c and be ok (I keep mine at 85-88).

Intensities are already separated by commas

Cheers guys, I may have a play around when I have some time then.

One last suggestion, make sure the clocks are stable and not fluctuating a bit. Low watts can cause errors. I turn my 290x power limit to +10 when mining, and get as low as .5% rejected on some pools.

interesting, I know the 290 core speed does fluctuate ever so slightly, this is actually a common issue with these cards and it causes the card to drop off of bamt's ui. A friend of mine actually posted a fix for it.

what do you mean by power limit +10? is that a parameter in the config?

[dgross0818]

Probably means PowerTune +10 instead of +20 (I think)

290's are a little weird to configure... one of my XFX's won't run on anything other than 947 (stock clock) lol... It also drops off BAMT 1.2 every once in a while, however, it doesn't affect shares so I don't really care.

well if you get bored and fancy fixing it, this is how to:

https://bitbucket.org/beebee/bamt/issue/2/gpus-drop-off-gpumon-and-web-interface

TLDR: you need to edit /opt/bamt/common.pl (search for "regex"). Replace part of the regular expression that reads (\d)MHz with (.)MHz

this sounds like an issue i had with bamt and my 290s

Interesting... A single rig (all rigs on same server and same address) was just on a different coin from all the rest for a while. Appears to be lottocoin, actually it just switched back to it again, while the rest are all doge'n it.

[pitobread]

So I have something interesting I found today.

Here is my hashrate.

http://www.middlecoin.com/reports/1D8D29KxcmPqHsmiypHcEdCc5HqnjYgat.html  <there was a small dip when i moved my machines and one went down last night for a few hours.

Here are 3 other users with a same overall hashrate

http://www.middlecoin.com/reports/1UYijXkzZh4qqQKUkHPeRfbELF3XKmWye.html  <<< very close rate and he makes double what I make

http://www.middlecoin.com/reports/1B2cs9cyAcmNKPjoGdGNUL92FToKSUQaXc.html <<< This guy has the same rate as me, I have been watching it all day and he is making almost double what I am in a day

http://www.middlecoin.com/reports/1D8D29KxcmPqHsmiypHcEdCc5HqnjYgat.html   <<< This one is lower at first but gets higher at the end.. but notice how the earlier payments are similar to mine with double the rate.

I have very few rejects, my pings are 25-35ms, my machines run 24/7.  No odd messages on my screen when running and I have ran it on litecoin/wdc/doge/etc before with no issues.  Why are they making way more than me?  Seems the sharing part of the pool needs tweaking if we are all mining the same and yet I barely make what someone with half the power is making?

edit: I don't have no submit stale

I have made an Android application for Middlecoin in my spare time. If you would like to BETA test it feel free to try it out. Would love to hear about your thoughts.

Please as this is an early build, the first time you run the program let it download and process the statistic from Middlecoin.com (currently no progress bar, could take a while) until you get the "Download Complete" message before you add addresses, search and check pool statistics. Thanks.

Untested but should work from Android 3.0

In MSI Afterburner, there is an option for "Power Limit." Double checking, I only have it set at +9 with my current clock of 960/1440. But yeah, when the clock bounces like that when at 100% GPU use, it's certainly low wattage. Upping this setting helps make sure it gets more.

My stock clocks were bouncy, too. Only have a 620w.

Absolutely. Increase the power play feature where it ramps up voltage based on load. The top end is not pushing power hard enough.

I've found that you can set it either as a cgminer command (--powertune) or in afterburner. In my case, I actually end up flashing the firmware with the new settings since I run in ESXi where I can't access those in a VM.

So...the powertune setting effects the same thing as power limit? Are you sure? If so, I need to edit my config file.

Oddly, I have powertune 30 set, yet it still bounces until I set power limit in afterburner.

[Spiffy_1]

Since the 14th I've had two payments that have never been received.  I've checked with the exchange that my address leads to and they have no deposit issues and no record of my btc coming in.  I'm hoping its just a mixup in the database but 2 days is a long time to wait for btc.  Pool operator I can give you the transaction addresses if you PM me.

I'm pretty sure max powertune is 20!

i'm not h20 but what is the address, should be easy to verify in the blockchain

Not 100% sure, but I had this problem, and played with those settings a lot. One thing I also learned... reboot when you change settings because old settings will stick and mess with your experiment. For example, if you set powertune to 20 and run for a while. Then you remove the powertune command all together, the old 20 value sticks...

But also I've never run at 30? I thought 20 was the max safe value.

This particular topic has been already been discussed several times. Last time was only a few days ago. The best theory right now is that it's server dependant (which I think we have one confirmation for) with the uswest/middlecoin.com server currently having the lowest profits. If that's the server you're using, try using one of the beta servers that are closest to you.
