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

I'd be curious what 6970 users have found too

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!

@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?

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.
Windows 7 64b Catalysts 11.6 AMD APP SDK 2.4 GUIMiner/poclbm -v -w128 +10% "power control" in ATI CCC
MSI Lightning 6970 (940MHz default) Memory downclocked to 685MHz (I dont see any change from this but others said it was a best practice)

XFX 6970 2gb 935///1375 65% Fan 354mhash/s I was not able to find flags that helped it at all.

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.

Actually he is right, I really dont like over volting but Im like f it I could use 40 more mhash. Increase it to 10% clock it 950//685 100% fan with flags -v -w128 and you will pull about 403mhash/s

haha ya I noticed also just now, thx for telling me though. Its wierd cause my 5770 tweaked fine with msi afterburner but my 6970 never did.

Try -v -W64 or -v -W256

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.

Downclocking the memory is to keep the temp down. 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?!

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.
