Title: [SOLD] *New* mining rig components: 2x5830, Biostar A870U3, PCPC Silencer 950W
Post by: bitfoo on August 18, 2011, 09:29:29 AM
SOLD to wknight.

I'm selling all the components required for a startup mining rig - all items are *new* and sealed (except for 5830s, see notes below). I don't need these any more since I just signed up for a mining contract with Shades Minoco.

  • 2x Sapphire Radeon HD 5830 1GB: $100 each (Note: these are brand new, but the "seal/sticker" is not on it. They were sold to me as new by MelMan2002 in this thread: https://bitcointalk.org/index.php?topic=34145.0 )
  • Biostar A870U3 motherboard - 2 PCIe x16 slots and 2 PCIe x1 slots, will support 4 GPUs in total - $60
  • 2x PCIe x16 to x16 and 2x PCIe x1 to x16 cable extenders from Cablesaurus - $50
  • PC Power & Cooling Silencer MKII 950W Power Supply - 80 plus silver rated - $100 (note: UPC code has been cut out for rebate purposes)
  • AMD Sempron 140 - $35
  • OCZ 2GB DDR3 1333MHz (PC3-10666) RAM - $10

Total - $455 (currently 41.7 BTC). Ground shipping is 1 BTC, US only. Not parting out at the moment. Bitcoin preferred (at current MtGox exchange rates). Paypal also acceptable, or cash for local pickup in Los Angeles. Since I don't have much rep here, I'll gladly do escrow on btcrow.com if you feel it's needed. Post here if you have any questions, and thanks for looking!

Edited: I'll also accept paypal, though Bitcoin is preferred.

I'm also throwing in a 2GB USB stick, preflashed with a mining distro of your choice (Linuxcoin, BAMT, etc) - everything you need to plug in and start mining right away!

Yep, for now at least. If I change my mind later I'll update the thread.

Any idea what hashrate you'd get from such a rig?

https://en.bitcoin.it/wiki/Mining_hardware_comparison (https://en.bitcoin.it/wiki/Mining_hardware_comparison) has a whole list of user-reported numbers for 5830s. It can give you anywhere between 250 and 340 MH/s depending on clock settings (I'd say around 300MH/s for stable, long-term performance). So the rig as I'm selling it will give you roughly 600MH/s, and can be expanded into a > 1GH/s rig by adding two more cards since I'm also including the necessary cables for expansion.

I would agree with those numbers for the most part. I have a total of 9 of those sapphire 5830's and mine average 325 mhash's with no crashes. They are not reference cards so they don't overvolt but I have mine set at 1005 on the core and 300 on the memory using the phoenix miner with phatk aggression=13 vectors bfi_int worksize=256. And they do not get very hot compared to most other cards mine are rarely over 60 degrees even at 1005 megahertz when the fan is 100%. At 100 dollars the 5830 is the best ROI you can get.

Everything went very well and as described. Shipped very quickly and even sent a picture of the tracking number and all.

Thanks again!
