He said - 15% rejects - is this Hrate worth this?

Every time a block is mined, a certain amount of BTC (called the
subsidy) is created out of thin air and given to the miner. The
subsidy halves every four years and will reach 0 in about 130 years.

I don't have 290X Tri-X... just Sapphire R9 290 reference. But here's some good settings, and perhaps a good pattern for them that could give good results for the 290X Tri-X  https://bitcointalk.org/index.php?topic=460181 |

Hi Guys,
I try to build a rig with 6 R9 290 Tri-x.
With windows or Linux, The computer just recognize 5 of them.
An idea to put the 6 on the same rig ?
ps : motherboard is Asrock probtc and my pci riser are on usb.
Thanks,

First step is to figure out what the problem spot is - card, cable, or mobo slot. I would.definitely suggest linux for all testing. 1. Identify the failing card by running 100% fan and noting the one that doesn't spin up. 2. Swap pci-e ports, try again. If a different card fails, it is then pci-e slot. Tell us which one. 3. Swap riser (change both 1X, 16X, usb, and power). If the other card fails, you probably have a faulty riser cable. 4. Finally, if 2/3 had the same card fail consistently, plug it directly into the PCI-e 16x slot, and leave all other cards unplugged. Does it fail to boot? Faulty card Faulty USB risers are fairly common. They also seem to burn out sometimes if you have too many plugged into a single SATA or Molex cable. |

My Gigabyte R9 290X is getting 863Kh/s with WU:780/m and 79C
setx GPU_MAX_ALLOC_PERCENT 100
cgminer --scrypt -o stratum+tcp://scrypt.megamultipool.com:80 -u user.user -p password --intensity 20 -g 1 -w 256 --lookup-gap 2 --thread-concurrency 24550 --gpu-engine 920 --auto-fan --gpu-memclock 1500 --gpu-powertune 20 --temp-target 80 --temp-cutoff 95 --temp-overheat 92
Why do you have GPU engine so low? And stop using intensity - switch to xintensity and you will see several percent hashrate increase. Is it possible to call xintensity inline in a .bat? I'm running a 280x and a 290 on the same rig, and if I completely remove intensity from the config, things start to crawl really slow :-/ |

--xintensity ...
Of course things slow to a crawl if you remove intensity - it defaults to i 8 then.

Hmm.. So --xIntensity isn't a replacement for --Intensity? I call them in the same config? |

Yes, xintensity replaces/overrides intensity. Are you using a version of cgminer (karoth's), or sgminer that supports.xintensity?

Apparently not! Where can I find a compiled version of SGMiner that can work with this voodoo? I'm running a 290 (Sapphire Tri-X OC version), but I'm not really able to get above 850ish KH/s (Closer to 860 I guess). I tried a variety of settings (including the ones you posted from your .conf file) to no avail, except the xI, as I was apparently doing it wrong in not actually having a compatible mining software. My card runs really cool! (at 1040/1500) Never going above 72 degrees (mining next to my 280x, which is hashing away at 760kh/s, super solid!)), so I'm really happy there, but would LOVE to get another 50kh out of 'er... .bat file as follows: (Device 0 is the 280x, Device 1 is the 290) Core clock: 1040 Mem clock: 1500 -I 13,19 -g 2,1 -w 256 --thread-concurrency 8193,20481 --lookup-gap 2 With these settings I get no HW errors, and <1% failure rate on the 290 (less on the 280x). If I increase the TC, or the intensity, I start to get HW errors here and there... Any suggestions for a direction to move? I've tried various clock settings, as well as multiple TC settings. -g 1 and -g 2 don't seem to make much difference either way. |

Stock cgminer doesn't support comma deliminated g parameters, so that might be part of your issue. 290s tend not to run very well with 2 threads (save the occational person that reports great results for who knows why...). Being capped around 860KH/s sounds like 2 threads to me - try -g 1 and see if you can get a better hash out of the 290.
As for sgminer binaries, I can't recommend anything myself because I compile everything direct from the git tree, but I believe the reddit announcement thread had binaries posted. Also, you could try karroth's cgminer fork which I believe he provides binaries for.
You could also just run two copies of cgminer (one for each card), using -d 0 and -d 1 on the two instances. Many people seem to get better results out of heterogenious rigs this way (can't say myself, as I run all homogenius rigs with the same cards, oem, and bios).

My tri-x is running quietly at 68c, 840 khs, wu 780, reject rate 2.5% with config below.
I can't get two instance running on sgminer for some reason, even with "device" : "1", and "remove-disabled" : true,
Running my gigabyte 290 (hynix) simultaneously at stock just seems to crash my PC and I don't want to overclock it to 1500 yet, looking for quiet moderate settings to start with. Any advice would be appreciated

975khs each cgminer 3.72+cgwatcher (same as my R9 290x's Club/Sapphire both same)
catalyst 13.12
I have outdoor winter cooling so temps are never over 75-80
2xSapphire R9 290x tri-x
But I broke a fan on one and need to know where to get replacement and how to fix the bugger
I hope can do local and not mail it to Taiwan
Anyone know?

Hi guys
Just bought a brand new Sapphire Tri-X OC R9290X. I see that everyone is getting at least 850+ hashrates however I'm currently only sitting at 470kH/s. What on Earth am I doing wrong? I've even changed the motherboard, CPU, RAM, HDD and PSU to see if that would make a difference and nothing. I'm running Catalyst 14.1 beta (also tried 13.12). Using cgminer 2.11.4, also tried other versions as well as sgminer with no luck. The batch file I'm executing is:
cgminer.exe --scrypt -o stratum+tcp://hk2.wemineltc.com:3336 -u username.1 -p x -I 19 -g 1 -w 256 --thread-concurrency 32765
I've many different variations from many different forums? I'm started to think I've got a dud card here. Can somebody help me out please as I'm only new to mining.
My PC is running Asus h81m-e M/B, i5-4670 CPU, 8GB 1333 RAM, 850W PSU (high quality).
Any ideas guys? I seem to be the only one with this card getting such low hashrates out of the box. The most I ever saw it get to was 690kH/s but for some reason I haven't been able to replicate this number.

I`m running a 290x Sapphire (not the Tri-X, the other one) and the 290x Gigabyte, getting the same hashrate on both, with the same settings.
986 kh/s
< 0.5% rejects
Temp 71-72 (with an extra fan)
(using MSI Afterburner)
+30 Power Limit
1025 Engine Clock
1500 Memory Clock
-44 Core Voltage
Fan Speed 80%
Using SGMiner (4.1.0) with zuikkis kernel on Windows 8.1
-k zuikkis --xintensity 370 -w 256 --thread-concurrency 32765 --queue 0 --scan-time 1 --expiry 30
This being said, I suppose the Tri-X version can easily go over 1 MH/s

Either use 1500 or 1250 memclock. Start from 1000 GPU clock and go up from there. Also, what are your temperatures like? Hot? |

Ok I'll give it a try, can you give me an example of the command line I need to execute in my .bat file? My temperate only gets to about 70 degrees C

by the way, 1500 memclock I've already tried and it made the screen flicker a lot, is something wrong with my card?

1500 is high for this memory and can cause artifacts... but because of the way timings are setup in the default BIOS, only 1250 or 1500 memclock will yield good performance. You can try The STILT's 290 BIOS (works on most Tri-X cards) which changes the mem timings so that 1375-1450 will yield the same or better performance then 1500, but I would get your cards stable before flashing to his BIOS. Basically tho, 1300 will be worse then 1250 on the stock BIOS, possible a lot worse. I am using The Stilt's BIOS on my Tri-x cards, and am getting over 980KH/s on the best card (1400 mem 1100 engine), and over 920KH/s (1375 mem 1020 engine) on the worst card. |
