Title: 290 mining rig
Post by: Hoffman on January 15, 2014, 04:57:23 AM
I have four-five Sapphire 290's I would like to get rid of, depending if I decide to keep one for my PC.  Along with a 1600w Coolmax ZPS-1600B modular power supply and 990F-XA-UD7 Gigabyte motherboard with AMD FX 4130 3.8Ghz quad-core processor and 2x 2GB memory.  Will include PCI-E extenders for the cards and a power supply compiler if you need them.  Hard drive not included.

Cards get 830-840 khash stock.  Temps were generally around 70 degrees C, lower when it was cold.

Has been hashing around a month on and off.

Sold five 290's to chanberg if anyone would like a reference.

Start bids at 2 BTC ($1680 @ 840 per coin) for the four plus mobo, ram, psu and cables.  Original packaging included.

Thank you.

Sorry but as these are used items, I don't realistically think they are worth this much (no offense).

I would absolutely be interested to take them but it would have to be at 1.6BTC through escrow (not negotiable.)

You say in the ad that you're including risers, and that your temps were around 70. Why in the pic are the cards sitting directly on the mobo? I've been running 6 290s since november, and 70 degrees is difficult to achieve for me when I'm using risers.

They're in a cool environment and I have spare risers laying around.

All but one are currently running under 70 degrees.

What was the fan setting at? My 290 card was only hashing at 820KH/s and fan was at 90%, sounded like a freaking jet turbine, and temp was hitting 85c...

willing to sell 2 of the cards by themselves?


Title: Re: 290 mining rig
Post by: Hoffman on January 16, 2014, 12:16:29 AM
Fan runs at 85%.

Prefer to sell the whole rig though you can make an offer.

Is it four or five 290s

Post by: riggityroche on January 16, 2014, 12:56:33 AM
During the month you've been mining, have the cards been sitting on the mobo like in the pic? or connected via risers? and if they've been connected via risers, why are they sitting on the mobo in the pic?

During the month you've been mining, have the cards been sitting on the mobo like in the pic? or connected via risers? and if they've been connected via risers, why are they sitting on the mobo in the pic?
At one point I had the risers on all of them.  Then I took them off later since they performed cool without them.

They're not too loud, don't get me wrong, they are a bit loud, but I've had a server that was way louder.

Current bid is 2.0 BTC + shipping.

Are you in the U.S.

Is this sold yet?


Title: Re: 290 mining rig
Post by: Hoffman on January 22, 2014, 04:22:24 AM
Highest bid 2.4 + shipping, will give this one more day due to my inactiveness.


Title: Re: 290 mining rig
Post by: Clayce on January 22, 2014, 09:35:33 AM
Is this (4) 290s or (5) 290s? Also you say you have all the original boxes right?


Title: Re: 290 mining rig
Post by: Hoffman on January 22, 2014, 09:17:11 PM
4, all original boxes included.

I may have to take the heatsink off the CPU though if you want it in the box, so you'll need thermal gel probably.
