You guys are scaring me...I just ordered the 7970 Gigabyte edition and it comes hopefully tomorrow. I only ordered the darn thing cause it said it got 769K Sad

Why is that scary?

Cause some of your numbers are really off. 650 isn't acceptable for a $450 dollar card. You can spend almost 200 less on a 7950 and get 650. I am guessing it is just a wrong setting. Even my nasty old 6850 is pulling 260 and its only reported for a little over 200.

What cgminer switches are you using? I've found setting vectors to 1 gets me better rates on my 7970 as well.

-v 1 -g 2 -w 256 -I 6 will get me about 660MH/s when overclocked to 1100Mhz core and 950Mhz clock. The clock settings are pretty irrelevant, but lower it can help with power consumption.

Exactly same settings here for me with the same hash rate.

I have a 7970 and I got it up to ~720Kh/s.

I did a lot of tweaking but you can try this:

That's what worked for me.

I'm gonna be switching to litecoins but i'd like to know what the best settings would be for me to mine the most?

Right now with
1100 Core
1500 Clock

I'm running 650 Kh/s

Quote

worksize 256
vectors 1
aggression 20
threads_per_gpu 1
sharethreads 32
lookup_gap 2
gpu_thread_concurrency 24000

That's my current litecoin.conf in reaper as well.

Any suggestions? Thanks!

Cop some 7950's.

I bought about 6 a month or two ago.

Probably I haven't tweaked my miner completely right yet but I get over 550kh/s for each card.

The hash rate per $ is just as good (or better) as 7970.

@ Intensity - i'm not sure what intensity is.. i believe 7? That's what I: is in CGminer?

@ Ratio, i put my clocks at 1200/1650 and that hasnt changed a thing

The gigahertz edition is not too hot. I've had great luck with the Sapphire 3gb OC version.

But your other big issue is that Core Clock/Mem Clock should be ~0.70 or LESS. You have 0.8

I'm using 1070/1500 which is 0.713

I had a 7970 for a day, trying to get it to work. No matter what I tried, I could not get it above 600 khs (scrypt for LTC). So you're already doing better than I managed. I'm wondering if it's a motherboard or software or some other thing. There are a lot of settings on cgminer to tweak, so if you've only tried default so far... give it a try. There are guides around for tweaking it. I was doing scrypt and read the script-readme in the cgminer distribution. There are some good threads here for optimizing, too.

Can anyone help me out here? I'm using 50miner (cgminer) currently with default settings
