Simple GPU miner with 1x 5850 and 1x 7970.

Pulls 370 watts at the wall with some tweaking of the GPUs.

59C for the 7970 and 68C for the 5850.

850 Mhash/s

 P.S. Picture was taken by Potato 2000 Grin


Only 850mh/s? Thats poor imho.
One 7970 can do ~700, one 5850 can ~320 easy

I don't like to mess with overclocks, it would get quite hot in the garage, instability issues, temperature issues, and high power consumption.

The higher hash rate vs power consumption isn't worth it.  In the end you'll have accelerated electromigration and dead cards.
pls wake up from ancient times with Pentium CPU.
You can increase GPU speed and reduce Voltage in same line.
When you go to set a Formula1 Race team, you can not start with a Golf R36 and hope to win. Wink

The problem is racing cars have constantly burnt out tires, while graphics cards have electromigration and total errosion of GPU long term  Wink

Here's my Lego mining rig




2x5850 still under construction (a third 5850 is on the way).

For a proper analogy, I'd equate worn tires to a burnt out fan, and electromigration to a blown engine.

Or smuggle a new toy into the kids' room because all other rooms are already full with overheating rigs.

Not sure if the EMR is healthy though.

Great analogy  Wink But if any "parts" in the actual engine break then you're doomed.

Anyways it's much better for me because I wouldn't gain much and it helps keep the temperatures low and my power consumption down.

No, they were just the cheapest choice (childhood legos). And you can change the shape anytime you want.

Not good  Cheesy   But I have cheap power so efficiency hasn't been my number one concern.

All the cards plus the bitForce single on the left get me about 8GH/s.  Electrical usage is about 3,680 watts and costs me .0479 USD.


Some things I want to do to trim my power is flash and downclock the memory of my 4 6970s and also downclock/volt/whatever the CPUs.  Not sure how much that will really save me though.

reducing memclock goes a long way.

Haha that's quite high, but you could see a huge decrease in consumption by undervolting and underclocking the memory.

Leaving the core the same is good.  My rule of thumb is to undervolt and underclock the memory while keeping the core at stock speeds.

Another question, did you redo the electrical to handle that load? Or was your pre existing wiring good enough to handle that amount of current?

I have the a/c and one computer on the circuit in the shop (its outside).  I have two other circuits coming through the wall from the inside of the house running the other three computers.  I did it all non-destructively, since I rent.   Tongue

Two of my computers only support 4 cards as you can see.  The other two support 6 and 7 each.  Those small computers are part of the high power ratio.  Also the computer rocking 7 cards is all 5830s (@900/300) which are power hungry.  That computer is pulling something like 1200 watts IIRC and only getting 2029 Mh/s.

I've been much more concerned with getting my hardware cheaply then getting the setup electrically efficient.  Most of the year I welcome the heat anyway.  This summer is going to be harder though...

Modus, when you say downclock the CPUs, are you talking about the actual CPUs on the motherboards or just the GPUs on the card?  If it is in fact the CPU, even with free electricity, I wouldn't have thought the risk of burning a CPU out would outweigh the extra ~10MBs you might be getting from them.

Nice setup by the way!  Is this outside, in a three seasons room perhaps?  If so, is humidity of any concern for you with the exposed cards?

Thanks for sharing!

Im not mining with CPUs...  I have them running at stock.  I have thought about downclocking them or undervolting them to save juice.  They have very little load ever placed on them and I dont think I would notice if they run slow.  I've never done that before though.  I have only overclocked for gaming with no regard for electrical use.  But Ill give it a shot sometime when I'm bored.  See how many watts I can save.

The room is 'outdoor' in that you have to go outside to get to it.  But its insulated, the landlord calls it the 'shop'.  My dog likes to sleep in there, the heat used to be nice.  Summer barely lasts 3 months here, but I put an a/c in anyway.

undervolting your CPUs will only save you a few watts, maybe 10 combined across all systems? Your CPU will run almost completely idle (unless you set the intensity too high - 100% cpu bug) while mining.

5830s can be undervolted to only draw like 100-110 watts a piece IIRC (while still staying over 300MH/s), which should put your 7 card rig somewhere closer to 800-900 watts with the same MH/s.

Either way, nice setup!
