Love the hanging rig option, it’s kind of close to the breaker/fuse box, is there some free electricity going on there? ;) :D

I’m sure with the Mrs here for a few days I can find something else to keep me busy ;)

But you are right, I had to rush out this morning and buy another CPU cooler so I could get the test rig running as the one I ordered from eBay hadn’t turned up

Lol…

It’s 7:33am in Australia and I’ve once again, spent the whole night being schooled by the gods of Crypto Mining.

I’m trying to build a prototype 6 card rig before I put in a big order. I couldn’t get a 6 PCIe slot MSI Mobo to read any of my Sapphire 280x cards. Such a journey I’ve been on, I tried everything, different operating systems, shorting the PCIe slot, making dummy plugs, prayed to 4 different gods…

Guess what it ended up being?

The Mobo didn’t like recognising the cards for the first time because they were undervolted to 1.075… As soon as I took them back to normal voltages they all worked on the new Mobo and [b]THEN[/b] it allowed me to undervolt them happily…

I wanted to pick up my prototype rig and smash it to pieces in a fit of rage… That’s one week of my life I want back…

haha ;D

Thanks for the post :)

Thanks, I appreciate the info ;D

updated :D - first post!

I sent them back after all… I tried EVERYTHING on the BIOS with same results. So I ordered 12 PCI-E X1 -> X16 risers from [url=http://litecoinminingparts.com/]http://litecoinminingparts.com/[/url] hopefully they should be here next week. Hopefully these new powered risers will do well with my Gigabyte Z77X-UP7 and ASUS GPUs. I could not resolve lock up issues. So USB risers are a no go thus far. On to X1->X16 flat powered risers…

What about using an air/air heat pump ?
So you use the warm air from your rigs and the heat pump compresses it to more/usable heat to warm up some water/liquid til 90degrees or something…

wow i’m the only one in sweden

Nej det är du inte! ;) (No you’re not in swedish)

ja visst!

I actually have one cgminer instance for every GPU, since if one instance crashes I only have downtime on that instance. Also, I use separate workers on all of them so I can pinpoint issues via pool statistics (ie which card is not working). You can’t have different pools/workers on one cgminer instance.

but even with that, you need to list all per-gpu settings separated by commas, or the next cgminer instance you are starting assumes that the settings from it’s cgminer.conf apply to all the GPUs.

Thanks Ignition I’ll give it a go. :)

Memlock is already 1500, glad that’s the best option.
I’ll try lowering down the powertune, if that keeps the temperature down then is great.
and will try tweaking the PGU.
thanks again

Yeah, I’ve ordered the 6 GPU rigs from Open Rigs and I think I’ll just squeeze in 6 with a 1500w PSU…

Ok I rigged up some dummy plugs now I got 3 to work at the same time… The fourth dummy plug I think is messed up because when I slide the resistors in they dont fit as snug as the others. I think I need a new plug… Will post back to let ya’ll know…

What a great idea! Thanks… Hopefully it wont be too much longer, I’m upping my game in the next month or so…
