I can give you every reasonable bit of proof to confirm its me including PayPal transactions, my email accounts as well as ID, don't make blind claims just because I cannot favour your deal

After a couple of weeks of no mining, I'm back.  Sold off a few parts and got an electrician to install some more outlets in my basement (been procrastinating 6+ years for this).  Pardon the poor lighting - that is next in my to-do list.   

I have them hooked up to two 480 rads.  My temps are 36­°C, 38°C, and 39°C respectively.  The lonely 7950 on the end is 41°C (not half bad considering).

It's a Nikon D90 with the stock 18-105mm lens.

And it's actually 3x 7970s and 1x 7950 in that rig.  The cooler is a Thermaltake Water 2.0 Pro.  The other rig has a Corsair H110 cooling a 7950.

Try this with CGMiner:


And keep your core/memory ratio at 0.5757575757....

So with a 1000MHz core, your memory should be ~1737MHz.

Some boards won't detect the VGA unless you short the slot as such:

The reason why they're so hot is because your Accelero is blowing hot air passed by the fins onto them.  By removing that it won't be as hot - hence my solution. 

Just using some spare 92mm fans for the cards and a 120mm fan on the bench setup.  The 7870 doesn't have any heatsinks on the MOSFETs and the 7950 already had a metal plate installed over the power circuity.

The 7870 doesn't have any monitoring for the VRMs but with the 7950 it is usually about 72°C versus 86°C before.  The GPU dropped quite a bit - on the 7870 it went from 73°C down to 44°C and the 7950 went from 82°C down to 47°C.

The one on the left is a Thermaltake WATER2.0 Performer and WATER2.0 Pro on the right.  They're very similar to the Antec H20 Kuhler series which all share the same OEM, Asetek.  On my bench, I'm using the Performer for my 7950 and it cools adequately (GPU: 55°C / VRM: 71°C).

You have nothing propping your cards up?  Aren't you worried that they will tip over?   

Got a new board, though I'm not sure why since the old one also had the same slot spacing.  But I got it at a nice price so I can't really complain.



Removing the PCI brackets helps lower the temps a little.  Plus they're not as loud.



My third mining rig:



Just realized that I need to reinforce the padding for the support beam.  Seems to be slouching a bit.   

Have a couple of miners in my bedroom.  Gets a little toasty, especially when the ambient temperature reaches 95°F.

Main rig:



Backup rig:

Currently the two 5770's are at 61°C and 53°C.  The lower one is at 68°C.  And my 6950 is at a nice 78°C.  Need to get a fan behind him.   


Hope this is what you were referring to:

Hmm.. Costco member?

Thanks!  You'd be amazed at how creative I get with their shipping boxes.   

Both rigs are using wireless USB adapters.  I would love to use Ethernet but unfortunately my room is on the second floor where the router is on the first.


Yeah sadly my Lian-Li didn't have internal USB 3.0 header cable when I purchased it last year.  It's unsightly in the back but inside it is much more organized.  And those are open PCI slots, it looks a little deceving.   

You can insert on end in C1, C2, or C3 and the other in C5. 

From the article:

It's the same thing as using a dummy plug, except that you can remove the dummy plug whenever.

Damn thick cables with caps on the ends.   

I fixed it just before putting the side panel back on. 

Updated one my miners to this:



And then I added this beastly rig in the same room.




Doesn't get that hot with the window fans blowing air out during the day and then blowing in at night.
