cg miner help

[Evostatic343]

im using cg miner 3.7.2 and if i go over 13 intensity i get hw errors please help!

Lol. Why would you go over 20? It isn't necessary and I don't think it's even supported.

sorry i ment if i go over 13

What card? 7970s rarely go over 13, they don't need to.

r9 290s

[Mentalguy]

try

 

 

-w 256 -v 1 -I 13 -g 2 -l 1  --thread-concurrency 8192

[AK0490]

Standard config for 290s is something like  -w 256 -I 19 --thread-concurrency 27400 -g 1

They like high thread concurrency and intensity

try

 

 

-w 256 -v 1 -I 13 -g 2 -l 1  --thread-concurrency 8192

Whats V for again ?

Look at this site and find your GPU

what is it ?

vectors

vectors

Explain please ?

[AK0490]

Vectors isn't used for scrypt mining, it does nothing.

 

Edit: the readme from cgminer says

--vectors XX (-v XX)

Vectors are NOT used by the scrypt mining kernel.

SUMMARY: Does nothing.

That's what I thought.

I just had it left over from btc mining, it was stable so i left it like that.

-I 20 --thread-concurrency 20480 --gpu-threads 2? 

8192 is really low

Try to follow the 7970 tuning guide located in scrypt-readme.txt 

Achieving a high hashrate can require hours of testing and fine tuning. Entering random number you are suggested to try don't always work out. Mining varies from card to card, to OS, to general hardware combination. 

---TUNING AN AMD RADEON 7970Example tuning a 7970 for Scrypt mining:On linux run this command:export GPU_MAX_ALLOC_PERCENT=100or on windows this:setx GPU_MAX_ALLOC_PERCENT 100in the same console/bash/dos prompt/bat file/whatever you want to call it,before running cgminer.First, find the highest thread concurrency that you can start it at. They shouldall start at 8192 but some will go up to 3 times that. Don't go too high on theintensity while testing and don't change gpu threads. If you cannot go above8192, don't fret as you can still get a high hashrate.Delete any .bin files so you're starting from scratch and see what bins getgenerated.First try without any thread concurrency or even shaders, as cgminer will try tofind an optimal valuecgminer -I 13If that starts mining, see what bin was generated, it is likely the largestmeaningful TC you can set.Starting it on mine I get:scrypt130302Tahitiglg2tc22392w64l8.binSee tc22392 that's telling you what thread concurrency it was. It should startwithout TC parameters, but you never know. So if it doesn't, start with--thread-concurrency 8192 and add 2048 to it at a time till you find the highestvalue it will start successfully at.Then start overclocking the eyeballs off your memory, as 7970s are exquisitelysensitive to memory speed and amazingly overclockable but please make sure itkeeps adequately cooled with --auto-fan! Do it while it's running from the GPUmenu. Go up by 25 at a time every 30 seconds or so until your GPU crashes. Thenreboot and start it 25 lower as a rough start. Mine runs stable at 1900 memorywithout overvolting. Overvolting is the only thing that can actually damage yourGPU so I wouldn't recommend it at all.Then once you find the maximum memory clock speed, you need to find the sweetspot engine clock speed that matches it. It's a fine line where one more MHzwill make the hashrate drop by 20%. It's somewhere in the .57 - 0.6 ratio range.Start your engine clock speed at half your memory clock speed and then increaseit by 5 at a time. The hashrate should climb a little each rise in engine speedand then suddenly drop above a certain value. Decrease it by 1 then until youfind it climbs dramatically. If your engine clock speed cannot get that highwithout crashing the GPU, you will have to use a lower memclock.Then, and only then, bother trying to increase intensity further.My final settings were:--gpu-engine 1141  --gpu-memclock 1875 -I 20for a hashrate of 745kH.Note I did not bother setting a thread concurrency. Once you have the magicendpoint, look at what tc was chosen by the bin file generated and then hardcode that in next time (eg --thread-concurrency 22392) as slight changes inthread concurrency will happen every time if you don't specify one, and the tcto clock ratios are critical!Good luck, and if this doesn't work for you, well same old magic discussionapplies, I cannot debug every hardware combo out there.Your numbers will be your numbers depending on your hardware combination and OS,so don't expect to get exactly the same results!
