Tweaking 7970 settings

[microzee]

Hey everyone, I'm not mining bitcoins, just working on the hashrate. I also won't be mining bitcoins (obviously). I have 2 gpus. One cruddy one to power my displays, and the 7970 to mine. It is a sapphire dual-x 7970 but I don't know the exact model. Check out this screenshot: http://imageupper.com/s02/1/1/P14002713681631060_1.png

I'm getting around 640. Anyways, what can I change? if I turn up the intensity to 18, my hashrate goes down. Should I turn up thread concurrency? Any flags?

Also once I have adequate cooling I would like to overclock. I went into the AMD Catalyst Control Center, then performance, then AMD OverDrive. In order to adjust stuff, you have to do an auto-tune feature first. It got up to 4000 mhz and it kinda scared me so I hit stop. Is that normal? I was wondering if maybe you needed a monitor plugged into it in order for it to test correctly or something.

It is better to use cgminer or sgminer. With below configuration I get 745khash.

Code:

cgminer --scrypt -d 0 -o stratum+tcp://pool -u user -p x --thread-concurrency 11200 -I 13 --gpu-engine 1055 --gpu-memclock 1500 -w 256 -g 2 --no-submit-stale --lookup-gap 2

I get 750kh/s with 1080 core and 1500 mem with +20% powertune at 1.1~1.15 volts. I=13,w=256,tc=8192,gpu-thread=2,vector=1,lookup-gap=2

MSI Twin Frozr III HD7970 OC BE with an Arctic Accelero 7970 Extreme cooler.

I use SGminer.

So I actually think somethings up with my card. When I bump up the thread concurrency or intensity or both, my hashrate goes down. If I just leave it I get ~650, if I bump some stuff up, it goes to ~595. Another thing that makes me think its messed up is this:

Not sure if you need this one:

Anyways, whats with the clock readings?



As a side note, I ran this card just fine overnight on standard 7970 settings. Then I run it again during the day and my computer just shuts off. There was still a light on, but if you press the power button it turns on for half a second and then back off. If you take everything out and put everything all back in it works again. That has happened twice. I don't get it because it ran just fine overnight though.

One more thing to add to this, I switched to sgminer, and now I can't get it to work at all! The problem is, it wont mine on my second gpu.

Code:

Code:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
"D:\Mining\sgminer-zuikkis-05-17-2014\sgminer.exe" -o stratum+tcp:/ftc.give-me-coins.com:3336 -u microzee.ftc -p 7623 --gpu-platform 1 -d 0 --thread-concurrency 8192 -I 13 -g 2 -w 256 --lookup-gap 2 --gpu-engine 1055 --gpu-memclock 1500
pause

It will either crash, or say the device doesn't exist, depending on the gpu-platform and d. When I was using GUI-miner, it did platform 1 and d 0, which appears correct if I do a -n.

Code:

u can skip gpu platform, and just add -d 0,1 

[microzee]

Code:

u can skip gpu platform, and just add -d 0,1 

It just says command line option set a device that does not exist. I don't get why it doesn't work since it works fine with GUI Miner.

I switched to cgminer for now, since it works fine. Right now though I'm only getting ~600 hashes.

If you have the same cards (2x 7970) you can also skip

Code:

-d 0,1

Anyway my setting for sgminer for 7970 and R9 270 is like that:

Code:

color 0F
sgminer -d 0,1 -o stratum+tcp://stratum.nicehash.com:3333 -u 1PdHRDrRxBsohPRJMxTa5cVLNriEbJUhdP -p d=64 --thread-concurrency 11200,21568 -I 13,19 --gpu-engine 1055,1150 --gpu-memclock 1500,1500 -w 256 -g 2,1 --no-submit-stale --lookup-gap 2

I'm just trying to get sgminer working right now. Why does cgminer work and sgminer doesn't?

I do not have the same cards, I'm trying to only use the second card.

My Asus 280X DCII does around 750 Kh/s with 8191 (yes a 1), I = 13, GPU engines = 2, worksize = 256.
Clock 1080 core, 1500 mem, that should do the trick!

Thanks, but I dont have a 280x. Anyways, I'm trying to figure out 3 things.

First, why doesn't sgminer work.

Second, why doesn't my readings work on gpu-z

Third, why did my computer crash twice.
