Topic: LTC mining: 7870 ghz edition, only getting about 280mhs Help? - page 2. (Read 11568 times)

I finally nailed 300khs with:
GPU core 1175 mem: 1450 (max for this card, fuckers)
And settings in GUIminer:
Thread conc: 8192, worksize 256 intensity 12.

I'm gonna save this, and give your settings a shot, and report back.

EDIT: With the settings you used crazyearner, I lost about 20kh/s. my heat is under control with the settings I have, so for now I'll stick to that.

But I'd REALLY like to push this over to 400kh/s.
I tinkered with clock settings on that 6670, and if I touch mem or gpu, at all, the thing goes apeshit. I get pink and blue barbells all over my 2 screens plugged into it and it just takes a dump, then the rig restarts. balls. I think I'll just let that fucker rock it's comfortable 60ish kh/s.

So, as for moving forward. LETS GET THIS 7870 TO 400kh/s!

I'll throw in a bounty of .5LTC. It's literally all I've mined so far! Wowsa! for now I think I'll stick to notroll.in until someone can tell me why that's not a great idea. (which I'd really like to hear, because 5% is a buttload over a long enough time)

so if you find me settings/setup to get my 7870 farming at or very close to 400kh/s, I'll send you .5LTC.
(without something dumb like unplug your extra monitors or something. These settings could be my overnight settings, too. I'm not expecting to get 400kh/s while using it.)


EDIT:

Some threads have suggested higher concurrency = more performance, but at the cost of system ram. I have 16gbs of ram in my system, and generally use about 4-6. Anyone have any recommendations for much higher concurrency? I tried 16000 and there was no improvement. a small loss over 8192.


I also tried reaper with the same settings, which started at 410 kh/s, but dropped down into the 260s after about a minute, which sucked.

For the 7870 Drop the I down to 12 I have this card and am regretting every buying it I can get it into the 400MH/s on BTC and alt coins and on LTC wont budge 300 I can get it to 300 mark but still it flips out on me at times but  working on it spent the last bloody week or so on it and still no where as good as my 5870 lol


--thread-concurrency 7680 --lookup-gap 2 -w 256 -g 1 -I 12 -v 1 --gpu-engine 1140 --gpu-memclock 1215

I will advise start low work your way to up the settings iver by putting them in a cgminer .bat file and doing it like that or using msi burner and doing the clocks on that but am also finding changing mem on afterburn with the 78 card is not working so had to revert to manual adding into cgminer

OK, two cards. 7870, and an older 6670.
A little more details on my rig:  the 7870 is my device for my primary display, of 6. the 6670 has 3 displays plugged into it, and onboard APU has 2 plugged in. Too many displays, for sure, work from home, blah blah blah.

Tried a lot of settings from stuff I've googled up. What I have now is, (using CGminer with guiminer scrypt)
No extra flags, thread concurrency 16384, worksize 256, intensity 14.
My RAM is set at 1450mhz. That's the max for this card, as reported by afterburner and CCC. GPU clock is set to 1100.
If I crank the intensity way up, it gets a bit of a way into the 300 mh/s, but at that point, I can't really even move the mouse.

What i'm looking for is the right freakin' settings for this bad boy, and if my unique setup might have any dumb caveats, here. Only one display is plugged into the 7870.

I also cannot for the life of me find settings that will work for the 6670, after a buttload of googling. Like seriously, my full time job is at least half googling, and I cannot find any settings that work.

I'd love to know what people are using for "I can still use the machine" settings, and overnight settings.

I know these are in the hardware comparison list, but the overnight settings crash the balls out of my videocard.

I'm also having trouble figuring out how to force an application to use a specific graphics card. I had assumed it will render with the graphics card the display is plugged into, but I'm suspecting some applications do not do that: I tried to pop a game on not-my-primary display, and it got pretty mad about it, soft-crashing my video driver.

And my final, hardly related question.
I've been mining on notroll.in. I'm having trouble understanding why this would be advantageous, besides that fact that it always pays: I am figuring PPS or proportional would be about the same, over a longer time, and I'm not sure if there is a better pool for me. If I can get both these bad boys crackin, I should do 400mh/s and 100mh/s each.


So, any help would be great.

PER SECOND OP POST: .5 LTC if you can get this bitch to or very close to 400kh/s. Easy, right?
