Hello,
I fixed the PSU crash by changeing the PSU with a 1200W model.
But now i have other issues, AMD driver chases o stock settings when i start the 3 video cards in guiminer-scrypt. , if i try to undervolt it crahes.
At one try i got all of them working and stable at 81 degeres, but at the next tryout huge temps and driver crash.
Any ideeas?

Start 1 #1: I run the miner on the first to GPU, good hashrates ±560, when i start mining the 3rd GPU-system crash/shut down

I also watch the GPU temperatures, it reached 90c on some settings - on other settings the GPU temperature was quite ok (maxing 81 for one GPU the others at about 60) but the GPU was reaching 99% constantly (on other settings the was to change in load).
Couple of ideas: 1. not enough power to the system, once you start the 3rd card the system will crash out, I would have thought 850w should be enough though. 2. getting too hot - run with case open and a big fan pointing straight at system. 3. one card is faulty - try mining with each card for an hour by itself. For 1 and 2 undervolting may help. You should be able to drop the volts (VDDC in afterburner) to 1.030 at stock clocks. I thought about this stuff also..gonna try some changes ..strage thing is that the last setting i used with afterburner worked and the sistem was getting 1500 ..but the pool was registering only 500 than i stop stated it again and crashed. Also i started all the miners with a gab better util each one got stable |

Ah ok. I'm trying to figure out if you have successfully run all 3 GPUs in 100% before the crashing? 850W sounds a little weak for 3 Turbo (factory overclocked) GPUs... Most PSUs usually don't perform with stability near their max load. Trying to eliminate the usual caveats here...
The PSU is at 92% efficiency, i saw a lot of forumers with this cofig and since i got the started for a little while i dont think here is the issue. Make sure when you start your 2nd and 3rd miner that in the drop down menu the right gpu is selected.

The case has 3 extra fans pointing exactly on the GPUs, i dont think is a cooling problem, since on some settings the temperature allmost leveled on a constat level when the 3rd GPU starts then the thing goes down.

Hello all,
Unfortunately i am facing some real problems with my new rig, this is the setup i just received:
CPU: AMD - Procesor AMD Athlon II X2 Dual Core 250 (C3) (BOX)
MotherBoard: GIGABYTE 990FXA-UD5, AMD 990FX + SB950, AM3+, DDR III, USB 3.0, PCI-E 16x, SATA III
PSU: Antec HCP-850, 850W, Modulara, Vent. 135mm, Efficiency 92% (80 PLUS GOLD)
Ram: Corsair Vengeance DDR3, 2x4GB, 1600Mhz (Dual Channel)
Case: CoolerMaster - CoolerMaster HAF 932 Advanced
Hdd: some old suff i found at home
Video Card:3 x Sapphire Radeon HD 7950 Boost, 3GB, GDDR5, 384bit, DVI, HDMI, Mini-DisplayPort, PCI-E 3.0
On a fresh windows i have installed the following:
MSI Afterburner
AMD SDK
AMD Drivers 12.8
GUIMiner
Start 1 #1: I run the miner on the first to GPU, good hashrates ±560, when i start mining the 3rd GPU-system crash/shut down
I thought i had to undervolt or something and restarted the computer.
I run cmd and enter: startx GPU_MAX_ALLOC_PERCENTAGE 100
and enter various settings in afterburner that i found on the forum, for one setting the rig lasted a little bit with all the GPUs started (although the pool did not show the same hashrate) but when i closed one GPU and started it again same thing happened.
Also with different afterburner settings even with 2 GPU running it crashed
I also watch the GPU temperatures, it reached 90c on some settings - on other settings the GPU temperature was quite ok (maxing 81 for one GPU the others at about 60) but the GPU was reaching 99% constantly (on other settings the was to change in load).
Any ideea how to fix ? do you have some recommended settings ?

I really have no ideea what to do...i am just looking at an expensive piece of computer.
I am offering a 10% out of the first month reward to the person that can help me with this one + 25$ via paypal.

I am Drewz, i work in investment banking and currently building my first rig for litecoins (i could use some help from the forum experts).
Please take my submission in to consideration.
Thank you,

maybe someone should develop a paypal2btc escrow service , paypal is to mainstream to leave behind
|
|
|
|
wow
totally agree to what bcminer9 said |
|
|
|

I think a valid user service should be developed, the market is getting bigger and new users come every day.

I have past experience with python, and i think about opening some web services for litecoin
