Title: 2x Radeon 6970s (guiminer settings) Post by: erek on June 19, 2011, 05:34:57 PM what do you guys recommend for mining with 2x Radeon hd 6970s?
is guiminer the best client, and also should i configure them to be in crossfirex or independently? also what about the 'extra flags' such as -v settings? any thoughts are welcomed for properly tuning this situation... thanks Title: Re: 2x Radeon 6970s (guiminer settings) Post by: Madehimself on June 19, 2011, 09:42:41 PM bump

Title: Re: 2x Radeon 6970s (guiminer settings) Post by: smoothie on June 25, 2011, 09:30:14 PM Anyone know how to unlock shaders of 6950s to get the same settings that of a 6970?
I've tried several online tutorials to no avail. Thanks in advance! Title: Re: 2x Radeon 6970s (guiminer settings) Post by: labsbitforum on June 25, 2011, 09:40:42 PM @oldminer. Thanks saw the notes on what settings were used for what is posted. My 6970 MSI lightning clocked at 940 yeilds 360 Mhash/s with no parameters in GUIMiner. If I add the -v -w128 switches that many said they used Mhash/s drops to 312 Mhash/s. Am I missign something obvious? Any ideas why my numbers go from bad to worse using the recomended parameters?
Title: Re: 2x Radeon 6970s (guiminer settings) Post by: labsbitforum on June 25, 2011, 11:44:38 PM I got the Mhash/s up to 400 on my single 6970 (MSI lightning). I was getting 360 Mhash/s without any parameters. When I added -v -w128 switches to GUIMiner it dropped to 312 Mhash/s. I use ATI CCC to raise the core voltage by 10%. Right away it shot up to 400. I was using MSI Afterburner utility to adjust it but did not see any change. Posting in case it helps someone else.

Title: Re: 2x Radeon 6970s (guiminer settings) Post by: labsbitforum on June 25, 2011, 11:57:58 PM Nothing help me until I went in to ATI Catalyst Control Center --> Performance --> AMD Overdrive unlocked clicking on the lock and set "Power Control settings" to 10%.
Have you tried that? I used the -v -w128 parameters used by many who posted 400+ Mhash/s on the wiki.

Increase it to 10% clock it 950//685 100% fan with flags -v -w128 and you will pull about 403mhash/s Title: Re: 2x Radeon 6970s (guiminer settings) Post by: shata on June 26, 2011, 12:00:12 AM Nothing help me until I went in to ATI Catalyst Control Center --> Performance --> AMD Overdrive unlocked clicking on the lock and set "Power Control settings" to 10%.

Its wierd cause my 5770 tweaked fine with msi afterburner but my 6970 never did. Title: Re: 2x Radeon 6970s (guiminer settings) Post by: Oldminer on June 26, 2011, 12:05:41 AM @oldminer.

Try -v -W64 or -v -W256 Title: Re: 2x Radeon 6970s (guiminer settings) Post by: labsbitforum on June 26, 2011, 12:08:37 AM I did not have to crank the fan up to 100% on the MSI lighnting. pretty good cooling on the card. I'm at 69 degress with 59% fan so its pretty quiet and cool.

It has no effect on the number of Mhash/s you will get but may shave of a few degrees on the temp and hey, who doesn't want a lower temp on the GPU right?! Title: Re: 2x Radeon 6970s (guiminer settings) Post by: hitndahedfred on June 17, 2013, 03:17:02 PM I am currently getting almost 500kH from one.
I am setting up another in the same box today. They are "identical" but we all know how that works right? Anyway my config for ONE is as follows --intensity 14 --gpu-threads 1 --shaders 1564 --worksize 256 --gpu-engine 900 --thread-concurrency 8128 --lookup-gap 2 --gpu-memclock 1550 -D Win 7 Ultimate X64,,,,SDK 2.7,,,13.1 drivers.
