      Let me know what you use from B&Q. I can trek over there to get some parts.

      Ever used a PCI-e splitter?

        Wow, I didn’t even know they made those… has some real potential for rig design.

          I have been thinking about using one. They cost about 180 bucks a piece. The only thing they do is allow you to have more cards on one board. But for that price you can get a new board, RAM and CPU combo. Another limiter seems to be the drivers, they are said to be only allowing 8 cards at max, but I have yet to see that. I got a bit stumped on my 7 card setup, without a splitter. If I get more cards I might just give it a try and see what those splitters can do.

          As a precaution though, they are meant for true x1 cards. They have tabs that hinder you plugging in 16x cards even if you cut away the back of the socket. So you would need a riser on top of it in some form.

            Never used a splitter for mining but i see no issues with them. Would rather plug straight into the mobo though (via a passive 1x - 16x riser). looking at that splitter you will need to cut the end of the socket off so you can seat the card. Most mobo’s can support 4 cards and 2* 4 card rigs will be easier to build/manage than 1* 8 card rig.

            as for B&Q… gimme a few mins and i’ll compile a parts list

                Here’s a closer image of how to assemble that lot. A bit “Mad Max” i know but it’s cheap and quick.

                      Hi NutNut, I notice from these pics that you do not appear to be running powered risers… I read in another thread here on the forum (sorry I don’t recall which) that despite the fact that the cards are all powered by the 6-pin PCIE cables from the power supply, they still draw a significant amount of power from the motherboard through the slots. In the post I am referring to, the OP warned against running (3 or more?) cards without powered risers as it risked drawing too much power through the motherboards main power cable - he posted a pic showing a blown pin - and ruining you mainboard. Have you ever encountered any problems?

                      I have a bunch of new equipment on the way, including powered risers, but I am nevertheless curious if they are required.

                      TN

                        Good question. I added powered risers to err on the side of caution.

                        Also what power supplies are you running nutnut? I have a 1250w and added a sync’d 800watt b/c my four Gigabyte 7950s were pulling more than 1250 watts. :P

                          Ahhh yes, the myth that is powered risers… All i can say is that i have 20* 7970s (5 rigs, 4 boards each) and NEVER had an issue. My risers never caught on fire, I’ve never burnt a pin out of the 24pin connector and I’ve never blown the tracks on my motherboards.

                          i use either Seasonic x1250 or, against better judgement, the Corsair AX1200. If you measured you power at the wall then that explains it. A [b][i]good[/i][/b] power supply will deliver it’s stated power to the components. The issue is that power supplies are NOT 100% efficient therefor a 1200w supply may pull 1320+ watts from the wall (based on ~90% efficency). In short, if your supply doesn’t trip and your rig seems stable, don’t worry too much about it. I have 1000s of hours on my psus and all is well so far. Good PSUs have a fair amount of headroom built in - just keep 'em cool and they’ll be fine.

                            Very satisfied with my seasonic 1250’s, but if you want 5-6 card in one rig im really loving the enermax revo 1500w, driven 3x7970 1x6970 2x7850 on a eig no problem. Doesnt even get remotely hot

                              Thanks Nutnut. That’s good information to know. I guess I’ll stop wasting money on the powered risers.

                              I’m running 4 7950s w/ a Seasonic 1250w and a Corsair 800w at the moment and I think w/ my MB I can run a 5th.

                              Before I really go much larger scale I need to work on a) additional cooling in the room b) power (I guess I’ll run a couple 20amp circuits).

                                If your running windoze you may struggle. I’ve heard many people have issues. Much simpler to have multiple 4x rigs running IMHO.

                                  I’m currently running Xubuntu headless :)

                                  I tried w/ a USB stick first but it was just way to slow so I dropped in a solidstate 32Gb drive I had laying around.

I’ve burnt a PCIE to Molex pigtail adapter once - when I looked at it afterward I discovered it used 18 gauge wire while the others had 16 gauge.

                                        Almost without a doubt! I use double copper motherboards and reputable psu’s. if you try to get away with buying cheap stuff you’ll get burned (pun intended). Buy cheap, buy twice.

                                          For one of my rigs, I plan on hooking up 4 of my 7950s.

                                          1. Seasonic SS-1250XM X-Series ATX PC Power Supply looks like it’ll be enough from what a read?

                                          2. You mentioned double copper motherboards… do you have a few recommendations? I was looking at this board:

                                          As always, I appreciate the advice here.

                                            PSU is practically a legend IMHO. I use 3 of them (would be 5 but stock at the time prevented it) and they run 4* 7970’s overclocked (happily pulls 1350w from the wall when hot) so they’ll be fine with 7950s.

                                            As for the Mobo i really cant comment except to say i use these, bit more expensive but i know they work so i’ll stick with them… http://www.amazon.com/GIGABYTE-GA-990FXA-UD3-990FX-SATA-Motherboard/dp/B0055QYKQO/ref=sr_1_1?s=electronics&ie=UTF8&qid=1370421880&sr=1-1&keywords=990fxa-ud3
