I'm getting hw errors when mining x15 with Radeon 5000 series cards. 7000 series and 280x work fine with sgminer beta.

Anyone have any ideas on this issue? The 5000 series hash, but get only hw errors and no accepted work results Sad

Interestingly the x11mod kernel compiled with sgminer v5 beta was a darkcoin-mod bin not x11mod bin so dumping optimized x11mod.cl into v5 kernel directory has no effect with v5.  Seems that v5 maps x11mod to darkcoin-mod Sad I tried deleting darkcoin-mod.cl and renaming x11mod.cl to darkcoin-mod.cl but compile fails Huh

However putting it in 4.1.0 kernel directory definitely works Smiley

Sorry I don't have 7990 Sad

My settings for X15 and X13 on the R9 280X and 7970s

sgminer.exe --algorithm bitblock -o POOL -u USER -p PASS -w 128 --lookup-gap 2 -I 18 -g 4 --gpu-powertune 0 --gpu-engine 1030 --gpu-memclock 1500 --gpu-fan 35-80 --temp-target 62 --temp-overheat 67 --temp-cutoff 74 --auto-fan

Getting about 2.7 in X13 and 2.0 in X15
Driver is 14.4 (gonna try 14.6 see if I can squeeze more)
sgminer 4.2.1


Took off the underclock added your setting's bumped me up to 7.1Mhs 62-63c Grin

Just want to throw a big thank you out here to all of the people talking about the new AMD drivers and new SGminer version out, in particular utahjohn. I've upgraded my linux rigs to the 14.6 drivers, updated my sgminer, tweaked my settings and overlocking and it's increased my hash rate on x11 by almost 50% over what I was getting before. Seriously... HUGE difference. Thanks a ton!!

Can someone with a 280x upload a .bin file for the new x13mod kernel on 14.6?

I am using four 280x's and the new miner crashes when using 14.6 drivers but is fine on 14.4. No matter what I try can't seem to get it working. Tried with W7,W8 & the new pimp but no luck.

I get an instant boost just by doing what they say there, no need to change the x11mod.cl or x13mod.cl just the bins and add the switch to the .BAT like they say there.

jumped from 3 MH to 4.4 MH in X11, from 2.2 MH to 3.1 MH in X13  (MSI R9 280X)

His miner works on Radeon 6000 series if I use the bitblockold kernel, but it does not work with 5000 series. Did you get your 5450 card to work with x15 ?

sgminer 4.1.0 X13mod with 7950 on 14.6RC2 ->> 2.6MHs

Note I am using optimized X13mod.cl kernel from OP.



utahjohn, I know that you are collecting 14.6RC2 data in this thread,  but is there a .bin file available for x13 from 14.6 drivers that I can drop into my mining folder so that I can stick with my 14.4 modded driver, like I have been doing with x11?
(I'm running six hd7950 cards on one Win8 rig.)

My x13 stats right now are that I'm seeing about ~2.33 Mh/s per card,  ~14Mh/s total using lasybears x11/x13 miner. I tossed in the modded kernel and saw the same hashrate with either one. Haven't checked amp draw, but I'll estimate around 8A based on card temps.

Nice man,  thanks!  Bumped me right up to ~2.67x to 2.68x  Mh/s per card,  or ~15.9x to 16.0x Mh/s total.

I have not played around with the config yet,  but the above was optimized for x11, other than the difficulty setting which I have since changed for X13 hashrate.
I'll post up again if I find any better settings.

Trying to avoid win 8.1 for as long as possible,  so thanks for the .bin file. Win8 is bad enough.

Baah... trying your bin for X13 and only getting around 2280KH or so at a total of 9.12MH for my 4x 7950's.  Same rig gets over 14MH on X11 with another modified bin. 
You are comparing apples to oranges LOL.  X11 and X13 are different algo.  X13 is a bit slower than X11.
You have not posted what your configs are, what sgminer version, what catalyst version.
This makes it hard to take any credence from your post.  Many successes with the bin and postings in the testing thread.

No, I understand X13 would get less than X11.  My point being that others are reporting between 2600-2800KHs with your bin and their 7950's and I'm hovering around 2260-2300KHs, so was just looking for some tips/advise.  Used most of my settings from my X11 setup, but tweaked a bit here and there to eek out a bit more.

My 4x 7950's are MSI TF IIIs.
Using PiMP 1.5.5-amd-13.12 (the 13.12 AMD drivers may be the problem here, but I thought the Linux 14.x series drivers weren't good for old cards like the 7950's)
SGMiner 4.1.0, X13mod and your bin

I would say your problem is with driver 13.12 ... update to 14.4 or 14.6RC2

hi guys, i have 280x cards but max speed in X11 is still 3.2 MH Tongue
anyone can give me 100% working source with 4.2MH/s on 280x ?
meaby i am using wrong source

sources from here: https://github.com/sgminer-dev/sgminer/tree/v5_0
branch v5.0
14.6 ati drivers

options
Code:
-k x11mod
-o http://eu-01.miningrigrentals.com:3333 -u xxxxxxxxxxx -p x
-o stratum+tcp://stratum.nicehash.com:3336 -u xxxxxxxxxxxx -p x
--xintensity 128 -w 256 --lookup-gap 2 -g 2 --thread-concurrency 8192 --shaders 2048
--gpu-engine 1050 --gpu-memclock 1500 --auto-fan
--temp-target 65 --temp-overheat 70 --temp-cutoff 80

R9 280x speed only 3.1MH
binary called darkcoin-modTahitigw256l8.bin
