Hash rates on 7970??
-
I’m new to mining FTC, but this is also an issue with LTC. I have 1 XFX CORE EDITION 7970, it’s OC to 1125/1500mhz. My settings are: Vectors 1, GPU THREADS 1, WORKSIZE 256, THREAD CONCURRENCY 8192 & INTENSITY 13*. I am avg 570khash/s on those settings. Now when I raise the intensity or try to do anything to improve my h/rate, it actually lowers to the mid 400’s khash/s. The Only thing I’ve found that improves my h/rate is changing the OC settings, but I’m at the max my card will go.
Does anyone have or know a fix for this? Or what the correct settings should be for mining?
Im using GUIminer-Script Alpha. Also my card is liquid cooled and never reaches 50*c. So I guess heat isn’t the problem.

I would play with your thread concurrency. I have 7950s that are set to 24000. I would also suggest ditching guiminer when you get comfortable.

[/quote]Thats what I am currently trying to find a good setting, thanks. And I know I want to switch from GUI, I am just not that familiar with other miners. Any suggestions on what would be the best? And how to set it up.
Is there a major difference from GUI miner and the others?
-
cgminer is the one i use. its runs similar to guiminer without the… gui! haha. if you want to start toying with it let us know. Also get a version earlier than 3.8 because they dropped video card support (im on 3.4).

[/quote]Thanks, ok I’ve DL 3.4. Been messing around with it, I for some reason have the hardest time trying to use console miners lol. I built this computer with a full liquid coiling system to mine with, but using a console to mine is like Chinese to me!

I’m running two Gigabyte 7970’s and the higher I turn the clock speeds the slower they hash. Here is what I’m running currently:
–thread-concurrency 8192 -g 2 -w 256 -I 13
Set the clock/memory speed to 1040/1500 and see what you get. Mine average about 720k/s. The one that actually has a monitor hooked to it generally hashes slightly slower; usually around 700 to 710 depending on what I am doing.
Good luck!

[/quote]Just tried that, no luck :-/… Thanks anyways. I’m thinking 570kh is the max ill get with this card.
I am thinking about getting a second card tho, I’m on the fence if I should get another 7970 or a R9 280X?

280x new are cheaper from what I am seeing. I would stay away from XFX. I hear people are having better luck with saphire and gigabytes.
also here is an example of a nice cgminer with config. I posted this the other day but couldnt find it. Have this a go and see if you can tweak more!

I also read on some forums a while back that those XFX cards needed a bios mod to get more out of them. You might want to dig around to see if thats the case.

[/quote]Yea I am going to go with a 280x, any1 use the CLUB 3D 280x?
Ill give your info a go, see if this works to up my speed… Thanks!

I honestly just gave up on my XFX cards.
Couldn’t push em above 600khash. I will never buy XFX GPU again! (those hydroballbearing fans are pure crap) -
You may want to look into my article on Power Optimization I have a few odd settings there for you to try. I had the same problem where I couldn’t get above 680KH/s with conventional settings on my MSI 7970s. I found that if you are getting below what you should be for hash rate compared to other cards with same settings you may need to play with TC for a while. My 7970s run on something odd like 21115 for TC…
My suggestion is to find the fastest settings you can achieve leaving TC at 8192 or 24000 and intensity at 13 or 20. Once you have that start playing with TC in jumps of 50 or 100 and look for spikes in hash rate. I did that and went from 680KH/s to 740KH/s in an evening.

Agree with svennand. I bought 5* xfx 7970 for one of my rigs and NEVER got above 560Khs.
I sent them all back and now run 20* Gigabyte 7970’s @ 760Khs - blown 4 of them now but they just get replaced on warranty. :)
