Title: CGMiner - Only 6 Intensity? Post by: Abacinate on April 21, 2013, 05:24:46 AM So I've been running the standard setup with my 7970 on CGMiner -w 256 -v 1 -I 13 -g 2. I've been getting a solid 660MH/s for a while now. Just now I tried stepping down intensity one by one all the way down to 6, and my GPU is running much cooler AND I'm still getting 660MH/s
Wtf... What's the tradeoff here? Why am I not getting higher MH/s at higher intensity? Thanks. Title: Re: CGMiner - Only 6 Intensity? Post by: btdir on April 21, 2013, 05:25:31 AM how do you step down the intensity???

Post by: Motivate on April 21, 2013, 05:32:13 AM i dont know this for sure but im sure its because its harder for it to do more threads then less threads at least i know thats what its like for all chips
Source's i'm Comptia A+ Cetierfied Title: Re: CGMiner - Only 6 Intensity?

Title: Re: CGMiner - Only 6 Intensity? Post by: moriewat on April 25, 2013, 06:07:56 AM Hash rate sometimes shows high on lower intensity on my 7950 rig but I believe the hashrate is technically "slower' look at your work per minute. Every system a bit different i have noticed

Post by: btcmcdizzle on April 25, 2013, 06:58:36 AM On a 7970, intensity of 7 is a sweet spot, so using 6 should not be significantly slower from a mhash/s standpoint. I'd be surprised if it ran significantly cooler since it's doing virtually the same amount of work; but if it is, perhaps you can push the card further @ I6 and find an even better 'sweet spot'.

These { "pools" : [ { "url" : "xxx", "user" : "xxx", "pass" : "xxx" } ] , "intensity" : "6", "vectors" : "1", "worksize" : "256", "kernel" : "poclbm", "lookup-gap" : "0", "thread-concurrency" : "0", "shaders" : "0", "gpu-engine" : "0-0", "gpu-fan" : "0-0", "gpu-memclock" : "0", "gpu-memdiff" : "0", "gpu-powertune" : "0", "gpu-vddc" : "0.000", "temp-cutoff" : "83", "temp-overheat" : "78", "temp-target" : "69", "api-port" : "4028", "expiry" : "120", "gpu-dyninterval" : "7", "gpu-platform" : "1", "gpu-threads" : "2", "hotplug" : "5", "log" : "5", "no-pool-disable" : true, "queue" : "1", "scan-time" : "60", "temp-hysteresis" : "3", "shares" : "0", "kernel-path" : "/usr/local/bin" } Uping to 7 did not change anything.

I have no issue with my current hashrate. It's pretty much in line with many other people at these clocks. I don't know anything about phatk. |
