can anyone tell me what is wrong with this config?

1st slot is 270 ( recently is 290 non x) and 2nd slot is 290 ( recently is 270) I have to use "--gpu-reorder" to work with it.

270 got at least 130 kh/s with less than 100 WU/s  

290 got 370-380 kh/s with 350 WU/s.

how can I make the 270 gpu faster than normal ?

vertminer config for sapphire 290 tri-x plzzz ? thanks

Hi to all.

Please, give me some advice about tuning 7970 card. I have an MSI Lightning BE (7970 with stock Core/Mem 1150/1500). All my experiments have resulted in 349-351Kh/s with some HW errors

My current settings is:
Thread concurrency 6136 (experimentally, this gives the best hashrate)
Core 1025
Mem 1495
Intensity 13 (12 gives no HW errors, but hashrate is about 220Kh/s)
Vertminer 0.5.3 (on 0.5.2 hashrate is about 290-300KH/s)
Added setx GPU_MAX_ALLOC_PERCENT 200 and setx GPU_USE_SYNC_OBJECTS 1 at system startup.
The HW error vs Accepted is nearly 50%

Does anybody have experience with these cards? What core/mem speeds should be? And what is the general ratio of core/mem for vertminer?

Thanks in advance.

[JohnnyDaMitch]

The ratio you can get varies depending on a lot of factors.

Raise TC at I=13, until the HW errors go away (well, a few a day is acceptable). It can be hard to give up the hashrate, I know! But it is an illusion - WU will confirm this, although it takes a really long time for it to stabilize.

Make sure you have 2 gpu threads. You can also experiment with work size in multiples of 64. Your memclock should be a pretty hard upper bound (beyond which weird shit starts to happen), but keep reoptimizing that engine clock with changes to the other factors. Don't push engine too hard though, only to the "bend" where it starts to hit diminishing returns on hash rate and rejects go up. If you don't see this then you probably can increment the intensity and find higher hash rates. TC has to go up with intensity, though (often times the best settings have raw intensity, which is 2^I, equal to TC).

[SpeedDemon13]

I've noticed that most cards in general, especially VLIW 4/5 cards, run good with a TC= 4x shaders count. That GCN cards with 514-bit memory, ie. R9 290/290X, can do TC=8x shaders count. Other GCN cards, 256-bit memory, can do from anywhere from TC=4x~8x shaders count with the exception of the hd7970/R9 280X (384-bit memory) which does 4x shaders count for the TC. Running default clocks sometimes helps too.

what does this mean? how can I fix it?

Your TC is too high for the device 1 card/gpu 1.

Is gpu 1 a 7970/280x? If yes, then a TC of 8192 or 8193 should work.

[Spoetnik]

the typical and classic max is 18 some *newer cgminer mod versions use a RAW method combined with a max of 13.
so i don't think 20 or 21 or higher would be valid and it would default to some other value.. i'm guessing

<snip>

20 was the old max in cgminer.  Up to 23 is valid in the newer branches of cgminer such as sgminer.  And any scrypt or nscrypt miner worth his salt should be using sgminer or some other maintained branch by now.

Classic intensity values (when you aren't using RawIntensity or shader-based XIntensity) launch 2^I threads. e.g.
I:13 = 8192 threads
I:14 = 16384 threads
I:15 = 32768 threads
I:16 = 65536 threads
I:17 = 131072 threads
I:18 = 262144 threads
I:19 = 524288 threads
I:20 = 1048576 threads
I:21 = 2,097,152 threads
I:22 = 4,194,304 threads
I:23 = 8,388,608 threads

As you can see, the number of threads increases exponentially with higher values on I.  This is why using Xintensity for tuning is so much more effective.  Not to mention these values rarely match up with the number of shaders on the card, and the optimal number of threads to launch is a multiple of the number of shaders on the card.  This is why I=13 is the most effective on many devices - because they have 8192/N shaders.

The sgminer git tree even has pool-specific algorithm/nfactor support, and preliminary kernel hotswapping!

interesting thanks for sharing

GPU_MAX_ALLOC_PERCENT 200

should be 100 ..as in 100 percent

i don't run with any errors ever.. it's 24/7 at 0 or i fix the problem

[nkzgwz]

I've run into a problem with my graphics card settings using Vertminer, as I have 1 simple intel graphics card and another stronger Nividia one. Whenever I start vertminer it automatically uses the intel one over the Nvidia one, is there any way to specify that I use the Nividia card in the vertminer.conf? I'm new to mining so I have no idea

[usao]

Ok, I have the latest version of vertminer and I have 4x 7850s which work well under cgminer (Scrypt). I get about 420KHs (Scrypt) for each card.
I tried to switch to vertminer. I looked throuh this thread and found recomendations for 7850s and tried some of them. Here's the problem.
Every time I try to start vertminer using any of the recommended settings, all Iget is "failed GPU"s when are OFFLINE from the start.
Sometimes, I get one or two of the total of 4 to work (seems random) but KHs is all very low, around 10-12 KHs.
I have 2 other miners running R9-280x cards just fine although the hash raes are about 10-20% below what others in this thread are getting, but they do work and are not failing or throwing any HW errors.
It's my effort to get the rig with the 7850s which is totally blowing up.
Again, ive cut-and-pasted several configs for the 7850 from this thread, but nothing seems to be working. The GPU's are failed right at the start and I can't bring them online.
Looking for any suggestions on how to proceed.
I mean, if I could at least get them online, then I could tune them, but when they report as failed immediately, there's not much tuning I know how to do to fix that.

Good afternoon;

That's my first time I try to mine, I wrote some of your configurations and the "best"   result obtained is:

Is there a bios you guys flashed these with I'm not aware of?

[RepublicSpace]

Not much can be done with just shy of 20 VTC. And not many places to actually spend it.

[LesterTheEight]

I would spend them if i could mine them. I have been trying to mine them for a few days now unfortunately i have not been getting anywhere. every time i start mining in a pool for vertcoin i check my hash rate on the site and it is 0, I am not sure why this is but its happening on all pools i try i am mining them like every other coin i mine however vert is the only one i have trouble with.

[Beaflag VonRathburg]

Well, read this whole freaking thread and I'm still having a hell of a time changing over all of my rigs. I've been GPU mining since the beginning of 2012 and Scrypt-N apparently requires some sort of magical powers I haven't quite learned yet. Currently, I run 18 rigs with 80 GPUs spread between them. Moving from rig to rig even between ones that have the exact or almost the same parts my results have not been exactly repeatable. With these wacky issues I've only been able to switch over four of my rigs

From reading this thread and having dealt with quite a bit of this before I think it would be a huge help if more people would record their operating system and display drivers with their settings. I'll add my findings with things so far. Please note since Scrypt-N settings appear to be some sort of voodoo your results may vary:

- All of my mining rigs have 4GB of ram in them. After dealing with some issues I've tested 4, 8, 12, and 16 GB of ram in multiple systems. The amount of ram in my system has had zero impact on my ability to run certain settings.

- Core and memory clocks do not seem to be as important as finding the right thread concurrency value. Testing across multiple 7970 machines found that lowering the memory clock had zero effect on the hash rate, but reduced heat output, and power consumption. Moving core clocks up or down 10-20 had only a 2-5 KH variance.

- Thread concurrency has a direct correlation to the amount of HW errors and disabled GPUs you have to deal with.

- In a machine with multiples of the same model GPU, I've found hash rate can vary up to 25 KH with the exact same settings.

Hi ,

I'm running 2 x 6  Gigabyte R9 280 -  using SMOS LINUX with Vertminer 0.5.4pre3

I'm using same settings as with "normal scrypt" like litecoin except  that I have to lower GPU CORE FREQ. TO +- 1000 Mhz - hashing 350 Kh/s with +- 6-8 Kh/s variance.

Aren't you supposed to get about 1/2 normal hashing power mining coins that use the N-Scrypt algorithm?

[mzahor]

I was getting 715khs with normal scrypt - now 350 because optimal setting is with GPU 1000 - 1010 and I'm running 990 ( lower temp )
