How to fix crashes and low hash rate on my new scrypt rig?
I need help to get past two major problems in my scrypt mining machine (see my config at bottom).
1 problem is system crashes during mining, even with low hash rate
2 problem is the low hash rates. 280x running at 400 k/hs and R9 290 at 180-400 k/hs
So far I have tried mining on Windows 8.1, Litecoin BAMT Linux and SMOS Linux with much luck. On Windows 8.1 I have gone through tons of AMD Driver versions from 13.1, 13.11 beta v9.4, 14.1 beta, 13-12, and bunch of other versions. Even tried couple of DDU clean ups. I have also tried different iners like cgminer, bfgminer, etc. Note on windows 8.1 I can't see GPU temp either. However, the hangs and low hash rates persist. One of the main issues is I can't get around play around with miner settings due crashes. On linux at least I can see GPU temps. But from my testing the system still hangs when running at 400 k/hs on my two R9 280x or 180 k/hs on R9 290. My setting for above on cgminer was (2x 280x and 1x 290 at the end): cgminer.exe --scrypt -I 12,12,12 -shaders 2048,2048,2560 --auto-fan --target-temp 65 Here is my hardware config: MSI Z77A-GD65 Motherboard(highly recommended on bitcoin.org board) Intel Celeron G1620 Corsair RM 850W G.SKILL 8 GB (4GB x 2) Sapphire Radeon R9 280x MSI Gaming R9 280x XFX R9 290x R9-290A-ENFC Anyone got any suggestions on what to try next? Seems like very hard to mine effectively, for me atleast...
Photo Gallery - http://imgur.com/a/z9Wka#0 Your looking at a complete scrypt mining rig which mines or creates altcoins. This mining rig will create cryptocurrency such as Litecoin, Dogecoin, and more. Currently selling this mining rig at 2100 USD which is a lot less than what I paid for the entire thing brand new. It has been mining dogecoin/litecoin/etc for 3 weeks and it turns out after my electric bill + summer time coming soon it will not be profitable for me as I pay .14 cents a kilowatt. The mining rig was restarted every Friday for basic dusting and maintenance and purs like a kitten. Price is negotiable depending on the drive your willing to make to Dallas TX (PM for Location). The rig has been in my garage and has always had temps of 76-78 or lower. One thing about this setup is you don't have to do a thing but sign up for the pool you want, type in your username/pass and your mining within minutes. No Setup required as i've gotten the perfect settings for each card on the rig. I've also placed each card to get maximum airflow without pulling heat from neighboring cards, henced the 280x angled upward to pull cooler air. It is also setup to automatically reboot and start mining on it's own in case of a power outage. I can also disable this feature as that is what I prefer to do. I like manually starting my rig once a week to make sure things are running flawless. These cards have all been undervolted, overclocked, and set up to be the most efficient and fast at what they do. Stability is key with mining cryptocurrency and I can proudly say this 2.6 MH/s mining rig has run a week at a time before I manually restart it to dust it. You can choose to let it mine tirelessly for as long as you want but I recommend dusting it often. I'm sure this baby can mine for months without being touched. All or most hardware has original boxes. Complete Scrypt Mining Rig With Aluminum Frame + Box Fan: GPU's:
Genuine 64-bit Windows 7 Ultimate Operating System
This does not come with a keyboard, monitor, or a mouse. I run this thing headless and directly remote in using splashtop so I have control of my rig wherever i'm at using my macbook. I am willing to ship the rig taken apart in 1 Huge Box with all original boxes inside + hardware if you pay the shipping. It will be carefully packed and sent via UPS, you can also add insurance which will also be paid by you. You can also meet me or come take a look at the rig if your interested, i'm located in Dallas Tx. PM me for exact address and phone number if interested. I will accept Chase Instant Pay, Dogecoin, Bitcoin, or Litecoin. I will not sell the rig in parts it's buy all or nothing. Note: As you can see I have two instances of SGminer running, the mining program I use. This is because I use different settings for the Sapphire 280x's and different intensity/thread concurrency settings for the R9 versions of the cards which are the 290x/270.
Hey! Thanks for all the help. I'm still plodding along. I found what appeared to be an amazing deal on a used Sapphire R9 290x ($150). Here's the catch: it was used to mine bitcoins for about a month. The owner assured me it has never overheated.
