New here - Want to build a rig!

Thanks for comments!
Well, after looking at MB, I’ve ordered only 3 VGA’s. Not going to use any risers, at least for the moment.
I will use mid tower. Keeping side open is not an issue. Sound is not an issue. Temperature… Well, it will be standing next to my air conditioning unit, so I think it should be OK…
However all of it will arrive only for the next year as VGA’s are pre-order for 27th december…
[/quote]Sounds like it should work out just fine then :)
Good luck! -

dedicated mining without building a case… you should get a workbench case.

So it has arrived :) 3 VGA’s does not fit without risers :'( bought some, waiting to be delivered.
For now trying with 2 VGA’s. Problem is that it only runs ~520 KH/s.
As I see, people talk about flashing bios, but I have no idea what files to use for that.
Tried searching, but can’t find any decent info apart 7970 flashing.
Could anyone point me to the right direction to achieve 700+ KH/s? :) -

[/quote]What kind of config are you running? You’d only want to flash if you had a locked bios and would want to overclock or drop the voltage. I would start with the miner configs first.
-
using gui miner. the only setting I’ve managed to find do myself is:
–gpu-memclock 1550 --gpu-engine 1070 -
Have a go with this and let me know how you get on
[code]–gpu-memclock 1500 --gpu-engine 1050 -I 13 -g 2 -w 256 --thread-concurrency 11200[/code]

I use currency 8192.
With the one you suggested it actualy dropped by 15 kh/s -
OK so post up your complete command string so we can see whats going on

this one runs around 605-610 kh/s.trying to increase gpu engine further drivers starts crashing instantly…

[/quote][glow=red,2,300]Set this to 2[/glow]
[glow=green,2,300]Is this another intensity statement in the same line?[/glow]
So what happens if you replace all of the above with this?
[code]–scrypt -u Kiwis.1 -p xxx -o stratum+tcp://pool.d2.cc:3333 --gpu-memclock 1500 --gpu-engine 1050 -I 13 -g 2 -w 256 --thread-concurrency 11200[/code]Your going to find life much easier if you write yourself a cgminer.conf file and put it in the same dir as cgminer, something like the below will give you a reasonable starting point to work from.
[code]{
“pools” : [
{
“url” : “stratum+tcp://pool.com:3333”,
“user” : “username”,
“pass” : “password”
},
{
“url” : “stratum+tcp://pool2.com:3333”,
“user” : “username”,
“pass” : “password”
}
],“auto-fan” : true,
“temp-target” : “70”,
“temp-cutoff” : “81”,
“temp-overheat” : “85”,
“api-listen” : true,
“scrypt” : true,
“intensity” : “13”,
“thread-concurrency” : “11200”,
“worksize” : “256”,
“gpu-engine” : “1050”,
“gpu-memclock” : “1500”,
“gpu-threads” : “2”,
“gpu-powertune” : “0”,
“kernel-path” : “/usr/local/bin”
}[/code]starting cgminer is as simple as just that type cgminer into your command line from the correct directory and away it goes
Also gives you the advantage of controlling the separate cards a little better should you wish too.
UM (it’s get very late and sleep might give you a better explanation)

Thank You! running at 710 KH/s! wonderful!
-
Hm, the dedicated rig is doing 710 KH/s, however I have another PC running the same single VGA, and there same settings for some reason only bumps it up to 580 KH/s :)

[/quote]Who would have thought you could tune another 100Mh/s out of a rig from hundreds of miles away, with no sleep ;)
Now you have yourself a good starting point, look in the cgminer directory on your machine for “scrypt-readme.txt” and do exactly that read it. The go get a coffee come back to the machine and read it again, arm yourself with a couple of hours and a bit of paper and you should be able to get that up by another 40Mh/s easily.

[/quote]Again if you want help your going to have to post more details, CPU, Mem, O/S, CGMiner version, Driver Version, Complete command line etc
Happy mining

Everything is working perfectly, however electricity usage went through the roof :o
I was expecting increase, but not a 100£ in 3 days increase…
Could it be that I’m wasting power because I have 1300w psu, and only 2 vga’s connected?
Also, how much could I undervolt it if anybody done that? -

I did not read everything in this topic, but you are running a 1300w PSU and got a £100 increase in 3 days?
That’s not possible!I don’t know the kw/h rates where you live but for example in the Netherlands it’s pretty expensive (around $0.29 kw/h).
Let’s say you run 24/7 1300w (1.3 kw)
1.3kw * 24(hours) = 31.2
31.2 * 0.29 = $9.048, so 9 dollar / day.
$9 * 3(days) = 27 per 3 days. -

[/quote]Yeah, that was my math initially. price here is 0.149£ per kw, so my calculations gives £4.5 per day cost. And I don’t believe it’s running at 100%…
My measurements are simple - I’m on top-up meter. I know my normal household uses up to £30 per week. And just before launching mining PC I’ve topped meter up to £120.
Today it has run out… That’s why I was so shocked. Now trying to take hourly measurements and will turn off PC off to see if it really is the one that uses insane ammount electricity. Though I think this much… it should be on fire by now… -
Sounds like you’re on an extremely inefficient energy plan
