Topic: Help needed with ATI saphire 290 (Read 578 times)

Here is the conf i am using :

]
,
"intensity" : "20",
"vectors" : "1",
"worksize" : "256",
"kernel" : "scrypt",
"lookup-gap" : "2",
"thread-concurrency" : "24550",
"shaders" : "0",
"api-port" : "4028",
"gpu-fan" : "75",
"expiry" : "120",
"gpu-dyninterval" : "7",
"gpu-platform" : "0",
"gpu-threads" : "1",
"gpu-engine" : "1025",
"gpu-memclock" : "1250",
"gpu-powertune" : "10",
"temp-cutoff" : "99",
"temp-overheat" : "95",
"temp-target" : "90",
"log" : "5",
"failover-only" : true,
"queue" : "0",
"scan-time" : "30",
"scrypt" : true,
"kernel" : "scrypt",
"kernel-path" : "/usr/local/bin"
}


With this i am getting 900 with 690 watt for the whole system. If i get powertune to 20 and memclock to 1500 i can get 915 but it gets unstable and more power so its not worth it. I can get even 950 if/960 if i get the engine on 1100 but again, power goes and it gets more unstable.
Still wheni get into afterburder the voltage is locked, at trixx its at 0 and i can only move up to 200 ( so i guess its locked also ? ).
So does that mean that the cards are voltage locked ? If yes do i need to get a new bios for them or i can change the voltage from the conf ?

The bigger problem right now is that i simply can NOT get the 4 cards running on any of the configs i have.
On one of the rigs i have GIGABYTE Z87X and on the other ASUS A85-V, both configs are with Win 7 64, SSD 64gb hard drivers ( cheaper then usual HDD's ) , 4g of ram . On the gygabite rig i am using Intel G3220 on the ASUS AMD A4 400.

So when i have 2 cards its all okay, its mining etc. When i get more then that i either can not even get past the first windows logo or i sometimes get into windows where it starts installing the devices and then i get the blue screen and its out.

Do i have to do anything special to get 4 GPU's running in WIN7 ? Need help !

Msi afterburner is the best.

i run mine at -44v in the msi afterburner on my 290 cards,(i dont have the 290x)

have you overclocked the cards? what settings are you running? and what is your system specs?

any one ?

Hey all, i would really appreciate some help !

Yesterday while i was waiting for the extenders i got x2 on each motherboard. I got them running at 915khs and the total consumption for the PC was 705-710 watt. I keep the window open ( its about 0 to 1 Celsius right now ) and they stay on 72(74 during the day when its hotter ) with fan on 75%.  I did not undervolt yet but will try to do that tomorrow. So my first question , what is the best tool to do that ? I was planing on using Trixx, if this is okay, what Voltage will you suggest ? 
Okay so my second problem is that windows 7 did not recognize the 4-th card. I have all of them connected, all runs well but i see only 3 cards, 4-th is missing. What could the problem be ? Any ideas on fixing that ?

915khs i think is great, they also are on a great temperature so i think if i manage to cut the power consumption with about 50 watt, everything will be just great. Btw what would be the optimal setting for this card in regards of khs/watt.

Appreciate any help !

Cheers all !
