Just set up my little bitcoin mining kit - advice welcomed!

[#Darren]

Hi all,

I just set up my modest little mining unit.

My setup is:

Processor:  amd fx 8-core processor  4.00 ghz    8.00gb ram    64bit

Graphics Cards:  gigabyte hd7970 x2

Motherboard - 990FXA-UD3

Power Supply:  750 watt


-----------------------------------


I am running GUIMiner x2 and it is bringing in approx 560 Mhashes x2   (1120 Mhash)

I am using slush's pool

Expected hashrate is not set to anything
Suggested Difficulty is set to 1


---------------------------------------

would appreciate any comments and advice

This should bring you up to 750 kh/s each card brah:

GPU_threads:2
--shaders 2048
worksize:256
intensity: 13
vectors:1
thread concurrency: 8192

Thank you - which file do I have to go into to update that data?

[autodidactic]

are you using GUIMINER?

[#Darren]

are you using GUIMINER?

Yes.

[autodidactic]

Should look exactly like that.

Ah, I see..    I am using GUIminer (v2012-12-03) which seems to be a different program to GUIminer-script

but I will dl it and give it a go - will report back with results.

Thanks again

Not a problem. I just didn't want you disheartened by the 560 kh/s that you get at first start. :p

You are giving him settings for something that is not bitcoin mining and the opening poster is mining bitcoins on slush's pool, so your settings will not help him.

Ah I see..  those are for litecoin?  Still, thanks to autodidactic, I am interested in litecoin and will give it a trial spin

Thanks,  I believe my cards are doing just fractionally lower than they are capable of.  I have them now running at approx 575-580 M/hash x 2

I'm running 5 of those same cards and they run stable at 660-675Mh/s for log periods of time.  Yes, you're results are "fractionally" lower, but IMO you could have saved $$$ and bought different cards if you were willing to settle for those numbers.

Advice;

- Dump GUIMiner and learn to love CGMiner directly
- Install either Sapphire Trix or MSI Afterburner
- Overclock your cards' GPUs to at least 1130MHz. Downclock memory to 600MHz to save energy and generate less heat

Should yield you a stable ~685MHs hashing on a 7970.

Why do you need an AMD FX 8-Core CPU for bitcoin mining?

So far, this is the best advice on this thread. CGMiner is awesome. I'm getting these same numbers stable on my 7970 rig.

I second this
