maybe try my settings, cant imagine how you get only 5xx khs  "intensity" : "20", "vectors" : "1", "worksize" : "256", "kernel" : "scrypt", "lookup-gap" : "0", "shaders" : "1792", "thread-concurrency" : "16384", "gpu-engine" : "850-1050", "gpu-fan" : "100", "gpu-memclock" : "1500", "gpu-memdiff" : "450", |

well if i didnt use powered risers my board would smoke in 2 minutes
5x7950 draw 15 A from the board which is build for maybe 7A MAX
with 4 cards and no powered risers it got so hot i was unable to touch it within 10 sec
|

sweeeeeeeeet ^^ 2.8 GH/s on one rig. \o/ (must be noisy.)
well 6x 7950 = ~3,8 GH/s  |
|
|
|
|
guess we all want to know, im glad its possible at all
|
|
|
|
|
just wondering if 5x7950 + 1x 7870 works as well? or maybe different vendors of 7950 work too?
i remember some1 told me he had running 6x7950 from different vendors, i ordered new cards but this will take a week

you dont need a monitor, only time i had a monitor on my rig was when i installed windows
if you need remote tools try teamviewer
|
|
|
|
so how did you do it?  |
|
|
|
How do you have 6 7970s running? What driver? What SDK? What OS? I have problems getting more than 4 on win7 x64 using driver 12.8 or higher. I'm barely able to get 5 going with 12.6
I'll drop you a PM to keep this post on my topic  im also wondering how to run 6 |

so can you tell me what thread concurrency you are using? i use 217xx and need ~1500gb ram per card
3 cards was the limit for 4gb running on win7 64 with cgminer
the ram does not show as "used" in task manager but unless you have enough ram cgminer throws errors...

for me amd_radeon_hd7900_win7_64 drivers (google) with 12.4 sdk work for 5 7950 cards
|
|
|
|
|
i have powered risers and i can use all the slots to run the cards, but only 4 or 5 at once
all cards get detected in the device manager so this cant be a MB problem?
it must be some kind of driver issue .... as on 11.12 i can run 5 cards
|
|
|
|
|
so i updated from 11.12 to 13.1 drivers ... 2 out of 6 cards show error 43 .. with 11.12 it was only 1
|
|
|
|
are you running 6x the same type of card? with current drivers i cant even run 5  |
|
|
|
|
im currently running only 5 cuz the 6. has error 43 in device manager
anyone got this? which drivers?
|

bei mir laufen derzeit 5x7950 auf win7 64, die 6. wird zwar im Gerätemanager erkannt hat allerdings Fehler 43 Genau das hatte ich mit der 5. Habe es nicht wegbekommen: Soweit so gut. Jedoch nach Treiber Installation sagt er immer im Gerätemanager (5 GPUS werden erkannt, jedoch eine hat das Warndreieck) "Dieses Gerät wurde angehalten, weil es Fehler gemeldet hat. (Code 43)" lad dir amd_radeon_hd7900_win7_64.exe treiber (google) und installier dann app sdk von den 12.4 treibern, damit laufen bei mir 5... |
