If you're getting repeated crashes, your stuff was broken to begin with. A video card should remain stable even if it is run at 100% utilization constantly. If cgminer crashes it, then in all likelihood other stress tests such as FurMark would do the same.

What kind of video card do you have? What cooler does it use? How is your case ventilation? Does GPU-Z show the GPU or VRMs overheating before a crash?

I didnt say it was repeated crashes. Using the default "highusage" settings for my card in the miner would cause the driver to fail every once and a while.

And most certainly my stuff not broken. Nice arrival at that conclusion. I hope you dont work in tech support.

My setup is in my sig the window is always open in here temps on the gpu have never gotten past 72 while messing around with this thing. Normal operating temps are in the 40-55 range. Ventilation is fine.

GUI miner in general is bad. Those defaults are there to give you round estimates of what you should be using for your card, they are not meant to be the most stable or optimal settings by any means.

I suggest you try cgminer if you want to mine LTC. Once you get the hang of cgminer it will make your mining life a lot easier and it is not that difficult to learn even though it may seem overwhelming at first.

Are you overclocking? Reduced voltage?

Not sure about Guiminer but driver crashes for me using cgminer was usually a sign of an unstable card. Upping volts/reducing clocks solved my issues.

I just started this week, so I'm not an expert by any means. I'll check out some tutorials for cgminer.


My card has never been overclocked or anything. Its just running at factory settings.

I'm currently enjoying free electricity, so is there any incentive to reducing voltages? Or should I max out every overclock setting available for the card?

Let's just hope the frenzy with be stopped or dampered by the time they get non-refs out or else, I can barely imagine how hard it will be to get our hands on those GPUs..

I was thinking about a single water cooled R9 290 to replace my 2 GTX 670s but not at the price it's at now!

I cancelled my order for the reference 780 for 450$ shipped with tax deal this black friday in order to wait for the non-ref 290s.

I am gonna be really pissed if they cost more than 430$.
It is heading in that direction and I am not happy...

From my experience underclocking seems to give better hashrates than overclocking. So far, this has been true for both my 7870s and 7790s. Keeping voltages and powertune intact, just changing (lowering) GPU/VRAM frequencies.

anyone know where to get powered risers?

I have 2--1 is powered and 1 is not. Is there an easy way to add molex power to the non powered one?

Sooo my new R9 290 is here but....it won't fit my current case. Didn't even think to measure, just assumed it would pop right in. My M1 should be here in a few weeks so I guess I'll mine the flavor of the month then. I had already planned to get the card and my power is only about $0.05/kWh so anything earned over ~$14/mo will cover the power cost. Just trying to recoup the card's cost.

1-So if i add one of my 6950 to my second picE port in my mobo. Do i have to reinstalled drivers?

2-And i take it i have to make another miner under wemineltc.com.

3-And do i have to change the Miner.bat notepad log i made under cgminer for the 290 to now account for the 6950?


Thanks guys.

I'd give them a call. The sapphire 290 I oredered on the 5th is on the truck for delivery as of 8am this morning. Wish I had gotten it friday but oh well.

Lol, just tendered to Fedex literally a few seconds ago with an estimated delivery date of December 17.

That would make purchase to delivery an 18 day long process (if it doesn't get lost or delayed)

Oh joy.

Xpage, you have to start up cgminer through a bat file. Post one if you have it, if not, I suggest looking it up.

I had the same thing with 3.5, gave 3.7.2 a try and now I am mining! Although I don't really expect to continue, just playing around.



Hope I don't burn up my 6770 just playing around Should i change some settings so my card inst working so hard? Not sure whats what. Power tune was at 20 and all I could find said it was about extra voltage which didn't sound safe so i lowered it. The wiki page had the -I at 18 for my card. I changed that trying to get 3.5 to work and haven't changed it back.

thread-concurrency 8192 --lookup-gap 0 --gpu-engine 850 --gpu-memclock 1200 --gpu-powertune 5 -w 256 -I 10 -g 1

Also, How bad is 77 kH/s? How many years until I have one litecoin?



Thanks guys, turns out that cgminer 3.5 didn't like my computer, 3.7.2 did the trick. wow this was easier than i though to setup, looks like i should have done this when i first saw this thread when i had cheaper electricity. Though i am mainly doing this to heat my room as it's cold and it's either this or get a space heater.

now i am going to have to go unlock my 6950 to a 6970 as i have a dual bios with switch reference and last i checked 90% of people with my model did get a 6970 that was downgraded to a 6950.

Do you the sapphire 6950 2gb? I have a few that were sitting in my closet and I think I'm going to do the flash. But 90% isn't even that great a success. What I want to do is undervolt it. Trixx seems to do it but under load it still uses the max voltage.

Yup. If you want to use the PC while its mining, set intensity to 13-15 and its still very responsive.
naah it's my server so I am good. Always knew that 1250W PSU wouldn't go to waste on the server

Anyone know how to actually get cgminer to use the conf file I created? Currently I am just using .bat file with commands but it would be cool to use the conf file.

1) No
2) No
3) Maybe. If you had stuff like worksize, clock frequency, gpu clock speed, etc in there. If it was basic and just had your username/pass, server/port then you do not need to change it.

Too lazy to go through hundreds of pages of posts but I got a Sapphire Vapor-X 7970 Ghz 3GB. Card runs at 1050 core, 1500 mem. Was getting in the 500's khs. Flashed BIOS using a Sapphire Dual-X BIOS. Upped the core back to 1050 and the mem back to 1500. Now getting in the 700's khs.

Used this BIOS.
Link to ATI flash utility.
Link to Rufus, a bootable USB creator.

**WARNING: Not responsible if you brick your video card.**

1. Download the Sapphire Dual-X BIOS, ATI flash utility, and Rufus USB.
2. Use Rufus and create a bootable USB stick.
3. Copy the BIOS and ATI flash utility into the USB stick you just created.
4. Boot your computer from USB stick.
5. Type in "atiflash.exe -i" without the quotes then hit return. This will show you the Device ID's of your cards.
6. To flash the BIOS, type in "atiflash.exe -f -p 0 bios.rom" and then hit return. If you have multiple GPU's installed, change "0" to the correct Device ID. Change "bios.rom" to the name of the Dual-X BIOS you just downloaded.
7. When done, reboot and your Sapphire Vapor-X should now be listed as a Dual-X.

Go into ATI CCC and you can safely boost the GPU core and mem speeds back to 1050 and 1500 respectively. Test mining. Should be in the low 700's compared to 500's before the flash.

Hope this helps someone.

**EDIT: Spelling mistakes**

Would that BIOS be compatible with my reference Powercolor 7970 3GB?

I have an original HIS. i did a major watercooling mod job but i rarely have used the card as I don't have much time for gaming, then when i did i found out it had capacitor squeal, liek a year after i bought it. So i doubt i can return it. However from my hour or so mining for fun, i heard no squeal.

So I might make this a full time heater for my room.


Also if i used GUI miner with the default 6950 i get a hash rate of 384, but if i use cgiminier and the following i get much less.

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
setx DISPLAY ":0"
cgminer --scrypt -o stratum+tcp://global.wemineltc.com:3334 -u xxxx -p xxxx --
thread-concurrency 24000 --lookup-gap 0 --gpu-engine 1100 --gpu-memclock 1250 --gpu-
powertune 10 -w 256 -I 19 -g 1

Note for the screen below i ram at 50 max allocation as i was surfing the web too. however with 100 it isn't much higher
