All,
Has anyone here built a 4x R9 290X rig? Please share your specs! I'm looking to buy a machine real soon (which will double as a serious gaming rig) and the electricity is free ;-)
Any experience on the motherboard, power supply, where is the best place to buy, etc. would be great.
Your hash rate would be useful.
I am looking to mine LTC/Dogecoins and hoping to reach 3.5Mh/s after a bit of OC'ing.

Personally I'd keep the gaming rig separate to the mining rig. No game today would benefit from running 4 290X's and it adds additional costs to mobo/CPU/RAM/HDD that really aren't needed.
PS: Where the hell do you get free electricity? o.O

This is because I am renting an office for business purposes (separate from bitcoin) and the electricity is free!
Any feedback will be appreciated!

Honestly I have a Rampage 4 Extreme motherboard which is supposed to be able to hold 4 in quad fire however I added my 3rd card last night. I have now 2 Sapphire 290x's and my third one is an Asus 290 since they were sold out.
Anyways, honestly, it doesn't look like I'll really be able to squeeze in a 4th one since it seems like the connections on the motherboard that you make for the power/reset buttons and the HDD lights, etc are in the way. Especially with the connectors on it looks like they are higher than a card.
I plan to buy another 290x or 290 soon so I will let you know. Either it will fit or I will be buying another motherboard since I dont want to keep using my personal computer for mining as I would rather have a stand alone miner. Still, anyone else fit 4 290's or 290x's on a RIVE?

I don't have a 4x 290x rig; however I have 4x 280x rigs. I just bought powered risers.
I'm running a cheap H61 board with a 16x and 3 1x slots and 4 500w psu's (I already had them laying around)

290X has a price at 150$ above 290. 290 Hynix hashes at 930-945kh 290X hashes at 990kh Not worth it and a waste of money, rather buy 5x 290 than 4X 290X At the moment i run with 4x 290 and mining my way to the fifth now (3 days left) Good luck on your rig.  |

I use the setup your asking about, though it's not a milk crate. I use this PC on a daily basis for everything while it is mining in the background. I got rid of the stock coolers in favor of watercooling. The entire unit is whisper quiet at 100% load and the GPU's never go past 60c overclocked. Motherboard is a Gigabyte Z87 OC Force 16GB ram 4x R9 290X cards 2x 1000w platinum rated power supplies. Each one hosts two cards and one pump with room to spare. I don't have any risers yet, but there are two more pcie slots available incase I need more. http://farm6.staticflickr.com/5510/12354377625_7a6974f5f0_b.jpg |

Could you tell me what kinda tower that is? It looks awesome as you can fit two psu easily in there.
Thanks

Thanks. The picture is already outdated in a matter of minutes. The two quick disconnects on the res's have been swapped with each other so now it is one giant loop instead of two separate loops. Temps are even lower now with the two pumps and 480mm/360mm radiators working together. The case is a Lian Li D8000. It' has a lot of room for creativity |

Lian li has the right idea with the double wide case on wheels for sure. Neat takes space. I can't believe how thin those 290x's look. Is that an entire EK system? |

Thanks! The video cards are using a full EK setup. The CPU is using a Koolance 380i. Radiators are SR1 Classifieds dual pass 360mm/480mm with the pumps going at full tilt 5/5. Fans are ceramic and serrated/knife edged. I am using my own ROM's for the cards, my own modified 13.12 drivers and a very specific CL/BIN file for CGMiner 3.7.3. I get about 1150KH/s from each card in full stable 24/7 mining. I have taken it as far as 1200KH/s per card, but only tested it for a few hours. Never had a chance to do much long term testing on it at 1200KH/s. I rent this rig out to people for mining. I usually promise them 4,000 KH/s but they get an average of 4500/4600KH/s when mining. |
