Topic: Consolidated Litecoin Mining Guide for 5xxx, 6xxx, and 7xxx GPUs (Read 624212 times)

I am planning using cgminer 4.8.0 for lightcoins and want the best settings for radeon 7 200 series!

I assume I need adding the following at beginning of bat file:
setx GPU_MAX_ALLOC_PERCENT=100
setx GPU_USE_SYNC_OBJECTS=1

Correct?

What the remaining settings for my actual gpu card?
It would help that some can provide actual code leading best setting!
Regards

No direct experience, no. I just read the forums, it seems it requires intense trading to be profitable... and I'm not sold on any Xⁿ coin to be honest.

What about X11 and X13?
Have you checked?

Not LTC for sure. After riding the GPU distribution we were all dumped.
GPU mining right now is mostly chasing the "innovative coin" of the week and even in this case ROI is fairly difficult.

Any one using their GPUs for mining profitably these days?
Some of my 7950s are resting without having any job.

Hi all,

Ive been ASIC mining for a while and thought id have a go with my GPU.

Its an HD6950 but im not pushing it yet, just learning the basics.

So, First question.

How do you tell CGminer not to use my Antminer U1s. I have them mining on BFGminer at another pool but by default CGminer wants to use them!

Many thanks for your help

Rgds

Ratters

** EDIT ** Ive unplugged the Ants and im getting a good basic KH/s on CG miner but nothing at the pool?!?

Any ideas?

This is a proper conf file for sgminer 4.1.0, it lets you run one and two gpu thread devices in the same instance and is faster than cgminer, use it:

{
"pools" : [
   {
      "name" : "Wafflepool",
         "url" : "stratum+tcp://useast.wafflepool.com:3333",
         "user" : "13jFjtuKoCfSd3bkLJQJg7EoBXWmebvA8x",
         "pass" : "x",
         "pool-priority" : "0"
   },
{
         "name" : "middlecoin",
         "url" : "stratum+tcp://useast.middlecoin.com:3333",
         "user" : "13jFjtuKoCfSd3bkLJQJg7EoBXWmebvA8x",
         "pass" : "x",
         "pool-priority" : "1"
   },
}

],
"intensity" : "20,20,13,13",
"worksize" : "256",
"lookup-gap" : "2,2,2,2",
"thread-concurrency" : "32768,32768,8192,8192",
"temp-cutoff" : "99,99,99,99",
"temp-overheat" : "95,95,95,95",
"temp-target" : "90,90,90,90",
"gpu-engine" : "0-1000,0-1000,0-1000,0-1000",
"gpu-memclock" : "1375,1375,1500,1500",
"auto-gpu" : "true",
"gpu-vddc" : "1.15,1.15,1.15,1.15",
"gpu-fan" : "85-100,85-100,85-100,85-100",
"gpu-powertune" : "20,20,20,20",
"expiry" : "1",
"failover-only" : true,
"log" : "5",
"queue" : "0",
"scan-time" : "1",
"gpu-threads" : "1,1,2,2"
}

This setup will run at 1100w gpu wise plus 100w-150w of ram/hdd/cpu/board, without undervolting (if the gpus are voltage locked)
To use it you have to create a txt file and name it sgminer.conf, then edit it and paste this inside and save. Then just run the sgminer.exe file to start mining using the conf.

I have 2x Sapphire Radeon R9 290 4GB (Hawaii PRO) and a XFX Black Edition 1250W 80+ Gold.

I'm thinking of buying 2x Gigabyte R9 280X Dual-X 3GB and put in the same miner.

How will this work W-wise and what would the config .bat look like in cgminer 3.7.2?

You must use cgminer 3.7.2, bfgminer or sgminer. GPU (or scrypt ?) mining was removed on recent versions of cgminer.

Hey guys. Am trying CGminer for the first time, but with the following in the bat file, it just does not start. Saya--scrypt is an unknown option. This is for a 6990. Any help would be awesome.

cgminer.exe --scrypt -o stratum+tcp://wafflepool.com:3333 -uxxxxxxxx -p x -I 17 -thread-concurrency 8000 -w 256 -lookup-gap 2 -g 1

Necro and probably already answered...but take out the http:// before your stratum. Your screenshot shows a different stratum than the config you posted.

 Since each cgminer inside guiminer-scrypt configures to merely one video card your question is confusing but I will give the answers that I think you may be looking for.

1. Create inside guiminer-script a new cgminer for each of your video cards.

 Realize each series of cards (ie: 7950, 7790, etc. have different settings that need to be used).

 Find those settings. Configure each cgminer inside guiminer-script (a tab will be there for each one after creating them).

For 7950 cards you can run these settings (but NOT for 7790 cards, see further below for them)
-------------------------------------------------------------------------------------------------------------
For 7950 cards ONLY
Thread concurrency = 24000
Vectors = 1
GPU Treads = 1
Worksize = 256
Intensity = 20  - (anywhere from 18 to 20 on a dedicated rig, lower that number if you get many
                        stales, say more than 3% stales.)



 Look through the link below for proper settings guidance for 7790's
https://litecoin.info/Mining_Hardware_Comparison

for 7790 cards ONLY from what I gather, on a dedicated mining rig try the following settings:
==========================================================
for 7790 cards ONLY
Thread concurrency = 8000
Vectors = 1
GPU Treads = 1
Worksize = 128
Intensity = 18  - (anywhere from 17 to 20 on a dedicated rig, lower that number if you get many
                        stales, say more than 3% stales.)



 Use Stratum = YES if your mining on a STRATUM Pool. Otherwise  Use Stratum = NO  (getwork)
-------------------------------------------------------------------------------------------------------------

 If on a Stratum mined pool, then next create just one STRATUM miner inside guiminer-script for those new cgminers inside guiminer. And configure the HOST and PORT for the STRATUM to the same settings as for the cgminers for each card.

 The HOST is the pools MINING address (for example)  pool1.us.multipool.in
 The port number is simply the port to mine on (for example) port = 3342

Recap:
--------
 EACH and EVERY CARD needs their own cgminer inside guiminer-script.
 Create those two cgminers.
 Then create one STRATUM for them.


 And for each pool you mine at repeat this procedure. Or get used to retyping all the data.
 I just configure new miners and stratum for every pool mined.
 Then flip between them as desired.


When done:
--------------
 1st fire up the Stratum. After it connects in a few seconds it will say connected inside it's tab, and also in the summary tab, you can also set the summary tab to be shown.

 NOTE: Using the summary tab to engage and disengage the miners is the easy way to do things after the miners are all created and configured.

 After the Stratum is connected then one at a time start your cgminers guiminer-script.
After the first one connects and reports hashing rate then engage the next cgminer inside guiminer-script. Caution: Engaging multiple cgminers at the same moment can result in driver crashes (screen lockup, hard reboot's). Avoid that issue, start miners one at a time, wait till hashing is reported to have begun to start the next miner/card.



 One can synchronize different brands of any series of cards with MSI Afterburner, but they all must be 7950's, or whatever series, such as 7790's. But not mixed and matched between two or more series of cards. One cannot sync a 7950 & a 7790 for example. They must be the same series, although brands don't matter to Afterburner since they all have the same AMD GPU's.


My rig uses the following:
================

AMD Catalyst Software Suite 13.4
+
guiminer-scrypt_win32_binaries_0.03
+
MSI Afterburner version 2.3.1

Three synchronized 7950 Cards


Thread concurrency = 24000
Vectors = 1
GPU Treads = 1
Worksize = 256
Intensity = 20  - (anywhere from 18 to 20 on a dedicated rig, lower that number if you get many
                        stales, say more than 3% stales.)

EXTRA FLAGS =  --net-delay  (for any slower internet routers along the pathway to their server).


 Three synchronized 7950 Cards (synchronized with MSI Afterburner v2.3.1, a stable version)
Two Asus 7950's, One Sapphire 7950. Synced to one Asus which is set as the master inside Afterburner, so that Afterburner overclocks them all in sync, and even after closing Afterburner and rebooting they stay in sync, and overclocked @ 1050 / 1500 with the power setting left at default. WARNING: Don't attempt to adjust Afterburner while miners are running. Or even starting Afterburner while miners are running, unless your rig is very stable, and even then it's wise to first stop the miners first.

 If your rig runs too hot try pushing any boost switch once (that switch/button will be on the video card itself, if at all. That should result in the lower voltage option. Or, worse, the higher voltage, in which case it will quickly get even hotter than before. WARNING: turn off your PC before pushing any boost switch/button on your video card(s).

 Happy Mining.


Caveat emptor - let the buyer beware!

has anyone successfully got a 7950 and a 7790 to work in the same miner?

what driver version did you use?

No i did not tried swapping the slots yet, i am using Asus r9 280x for my monitor.

I am using

850watt PSU
16gb ram
core i-7 2600k
windows 7 ultimate 64 bit

when i run them individually, one at a time mining speeds are good

Radeon HD6950 gives me 460~470Kh/s  with 70~75c temperature
 
Asus r9 280x gives me ~750Kh/s with 70~75c temperature

but when i run them simultaneously from 1 bat or even with 2 bat files from 2 cgminer different folders Asus r9 280x speed drops to ~574Kh/s

https://i.imgur.com/xck5VRf.jpg[/quote]


Update:


Made some changes in bat file and managed to rise the Asus r9 280x speed to ~625Kh/s, summary speed from both cards  1.090Mh/s with this config


But now Asus r9 280x is crashing after 15~20 minutes.    Any help?

Did you try swapping the card slots?  Which card are you using for your monitor?


-tb-

I made some changes


They did not made any positive effect on speed or temperature. 

speed ~ 1.035Mh/s

temp 72~75c

Any suggestions are more than welcome.

Hello, i am mining with Asus r9 280x & Saphire HD6950 with cgminer 3.72 i know that this cards have different g so far i managed to get 1.037Mh/s when i run both of them with this cofig:
 
 
 

Radeon HD6950 gives me 460~470Kh/s  with 70~75c temperature - i am happy with this
 
Asus r9 280x gives me 560~570Kh/s with 70~75c temperature - i think it's to low, because when i run only Asus it gives me ~750Kh/s with this config:

Please advise how to encrease my hash rates by minining with this two cards.

when u start cgminer without -T or --compact => u see only "black screen" with 5970 cards
-T gives u lined text results
--compact give u compact view == no detailed info / cards(cores), just 1 line for overall stats => but u can change settings by builtin commands! etc

can you please explain, its helping for what? so surely we can add.

5970 users add --compact
