1  Alternate cryptocurrencies / Mining (Altcoins) / Re: 3 x sapphire 7950 low speed or freezing on: February 23, 2014, 07:08:15 PM
and still big difference in hashrate?
2  Alternate cryptocurrencies / Mining (Altcoins) / Re: 3 x sapphire 7950 low speed or freezing on: February 23, 2014, 06:56:14 PM
uninstalled in safe mode all drivers with Display Driver Uninstaller

using this config

hi
windows 7 74bit
I just used the driver cd that came with it
where I can see what version it is?

and where I can download this 13.4s + 2.9 SDK ?

I found this one which I am downloading now
AMD-APP-SDK-v2.9-Windows-64.exe
is this the correct one?

however I cannot find 13.4s?
4  Alternate cryptocurrencies / Mining (Altcoins) / Re: 3 x sapphire 7950 low speed or freezing on: February 23, 2014, 05:07:30 PM
here the current state
to gpu 0 I have the monitor connected, would it be because of this so much lower?
and why is there such a big difference between gpu1 and gpu2?
5  Alternate cryptocurrencies / Mining (Altcoins) / Re: 3 x sapphire 7950 low speed or freezing on: February 23, 2014, 05:00:54 PM
ok changed powertune to 20

howverb I see directly already all cards still have different hashrate?

could 1 reason be because on 1 card I have the monitor connected?

is it possible to use the onboard vga for the monitor? and the cards only for mining?
I tried, but cgminer didn't see my cards anymore then?

hi
I have running 3 x sapphire 7950
I tried many configs
I can get it on around 600kh/s but then allways freezes
the fastest a littlebit stable I get it is this



I currently use this config

also 2 cards are way slower?
any ideas?

hi
I currently run this

"intensity" : "19,19,19",
"vectors" : "1,1,1",
"worksize" : "256,256,256",
"kernel" : "scrypt,scrypt,scrypt",

"temp-overheat" : "85,85,85",
"temp-target" : "65,65,65",
"api-mcast-port" : "4028",
"api-port" : "4028",
"expiry" : "120",

"scan-time" : "30",
"scrypt" : true,
"temp-hysteresis" : "3",
"shares" : "0",
"kernel-path" : "/usr/local/bin"
}

now the fans are noisy

I tried removing this line
"gpu-fan" : "0-85,0-85,0-85",

then I believe it should increase the fan when it goes over 65degrees
"temp-target" : "65,65,65",

however that didn't work they went quickly up to 70+ without the fans going any higher?

14  Alternate cryptocurrencies / Mining (Altcoins) / 3 x 7950 but different kh/s on: February 07, 2014, 09:17:15 PM
hi
I have build a rig with 3 x sapphire 7950
all cards have same config
but all 3 cards give diferent kh/s

how is this possible?

I already swapped cards, riser but its allways the same slot that's lower speed
could it be motherboard problem?

15  Alternate cryptocurrencies / Mining (Altcoins) / Re: Sapphire 7950 2 of 4 have low hashrate on: February 06, 2014, 11:48:00 PM
good one is 630 kh/s
and bad one goes quickly down to around 550 kh/s
will try some more things and otherwise I think I will open my own topic
anyway if I will find the solution I let you know
16  Alternate cryptocurrencies / Mining (Altcoins) / Re: Sapphire 7950 2 of 4 have low hashrate on: February 06, 2014, 04:30:54 PM
yes I can now confirm
with dummy plug still 1 card lower then other
so what else could be our problem?

ps I changed the cards and its still gpu1 that's slower
17  Alternate cryptocurrencies / Mining (Altcoins) / Re: Sapphire 7950 2 of 4 have low hashrate on: February 05, 2014, 06:40:21 PM
I have 2 7950 cards, actually3 but only 2 in this rig while waiting for an extra riser
anyway 1 got 630kh/s
while the other start also at 630kh/s
but then quickly goes down to 550KH/s or something

to 1 I have a monitor connected, to the other nothing
maybe because there is no monitor attached speed goes down?

I am waiting for some dummy plugs to arrive to test it

any way to see which gpu0 and gpu1 is which card?
18  Alternate cryptocurrencies / Mining (Altcoins) / Re: Sapphire 7950 won't reach 600 kH/s on: January 26, 2014, 04:16:15 PM
I have the same card, and the same problem as you
I am also struggling getting it over 500-550

as soon as I set intensity higher as 13 I get hw errors?

also no reply on email for them?

I send a litecoin to bter yesterday
still nothing received?
is this normal?

Let's think you do a donation to help BTER Doge trade market  Cheesy

what you mean with this?

ps now its been 2 days, and still not received in my bter account?
