Anyone running 6950's?

[digitalnav]

What settings are you guys using? If I use anything over  12 Intensity it gets tons of HW.

Le What?

Le What?

I have a 3rd rig with 4x 6950s. If I use anything over 12 intensity they get HW errors. Otherwise, im getting around 240k per card. (My 290X's get 860 each  :lol:)

12 Intensity? 

[digitalnav]

12 Intensity? 

-I 12

[beebskadoo]

-I 12

Yep, still haven't got a clue.

What are you current settings?

 

Try something like this

 

clocks: 900/1250

cgminer.exe --scrypt -i 19 -w 256 --thread-concurrency 8192 

 

Don't run them in crossfire either.

Yeah there not crossfired. Ill try that after.

Currently its set to -d 0,1,2,3 -I 12,12,12,12

[RuecanOnRails]

another thread concurrency to try would be 14208

On all 4 cards?

Also, should mention. 3x are XFX card and one is a MSI Twin FRZR

I run 2 6950s, one unlocked to a 6970. I use:

925/1250, -i 18, -w 256, thread concurrency 8192. Be sure to use 2 GPU threads.

hash rate?

[algoat]

hash rate?

440kh for the msi 6950, 485kh for the sapphire unlocked to 6970

[digitalnav]

440kh for the msi 6950, 485kh for the sapphire unlocked to 6970

So im missing out on about 500 khash

Have you tried 2 gpu threads?

[digitalnav]

Have you tried 2 gpu threads?

-g 2?

[algoat]

-g 2?

yes

[digitalnav]

yes

Ill give it a shot Monday

I have a MSI Twin frozr OC edition Radeon HD 6950 2GB.

 

Overclocked to 840mhz on core clock, 1325mhz on memory clock. Intensity 13 gets me 290 kilohashes.

Intensity 20 gets me 420. Currently using Intensity 13 because 20 lags up my system like hell. 13 is the highest it can go without screwing up everything and making it lag.

Holy crap how are u getting 440kh? Is it on intensity 20? If it is, for me on intensity 20, my MSI 6950 (twin frozr 2gb) is only getting 420kh , on 840mhz  core clock and 1325mhz memory clock.

intensity 18.  I might be able to get an extra 10 kh on -i 20, but its not worth the extra stress on the GPU. I find it runs best on stock memory of 1250, overclocking it actually brings the hash rate down.

I take it back, i18 gets a ton of HW (which im assuming means hardware error?)

 

Gonna try a lower intensity, overclocking helps hash rate for me.
