Rig 3
HP xw4300 motherboard - 1 16x 1 8x 1 1x pcie slots
2 gigs ram total all 4 slots occupied
socket 775 cpu (says processor not supported on boot (core 2 duo I believe, but boots and runs bamt fine) + heatsink/fan
power switch
2 1x to 16x non-powered risers included
HP/Delta Electronics 800 watt power supply
sata to pcie and/or molex to pcie connectors included

MSI 6850 - occasionally has to be reset as temp shows 510* and quits mining has been mining 2+ days currently stable
HD5830 Extreme - has an aftermarket fan clipped on the heatsink (runs cooler than any other cards I own, but can include a brand new arctic accelero L2 plus)
H6790 - 679F1GD - different fan is glued and spliced on this one as well temp runs fine

4 gig jump drive running BAMT 1.1 can be included if needed would be default install (this one is wrapped in black electrical tape since the casing broke)
This is currently running at 690Kh/s with no overclocking those 3 cards are capable of 780-800Kh/s when overclocked


2 of the cards are hanging from their metal brackets from wires attached to the ceiling they are not magic or floating without assistance!

Rig 4
HP DC5800 motherboard - 1 16x 2 1x pcie slots
3 gigs ram total all 4 slots occupied
socket 775 cpu + heatsink/fan - This socket 775 bracket did not fit right so had cardboard on the underside of the mobo to pull the heatsink tight and the fan is screwed right into the heatsink.
power switch
2 1x to 16x non-powered risers included
HP/Delta Electronics 800 watt power supply
sata to pcie and/or molex to pcie connectors included

HD 5830 Extreme - occasionally artifacts fine after reboot
HIS 6870  - fickle - starts at 0KH/s but mines fine after restart of mining software

No jump drive or hard drive included - this is currently running fine on win7 because bamt complained and would show GPU errors so unknown if BAMT works with this one.
This is currently running at 550Kh/s between the 2 cards with no overclocking those cards are capable of 600+Kh/s when overclocked.  No new pic, but both cards are in this rig now in a "milk crate" frame.  This rig takes time to get working correctly.  Currently win7 64 bit, bfgminer 3.10, 13.12 catalyst, sdk 2.9, cgwatcher restarting bfgminer on hashrate drop or dead/sick cards.  Do not think you will plug this in and go as I kept getting gpu faults within BAMT which is why I switched to Win7, but has been mining fine for 3 days on the above config (bfg miner relaunches 1-2 times a day).

Extra Card Graveyard
HD5830 Extreme - Bare Card does not detect in win or bamt
VT5850 - fan/heatsink - does not detect in win or bamt
6950 - H695FN1G2M - Bare - can throw in a gel icy vision cooler with no mounting screws or hardware with this one - this card had heavy artifacts and would not mine last time I tried installing it
Diamond 6970 - detects by both win and bamt will mine for a second then lock up showing a negative temp reading?
Radeon Ref 5870 - fan driller and oiled - detects in win and bamt - will mine for a few minutes then rate drops to 0

Understanding this is mining hardware and as I did the best to describe any issues it can be fickle as many of you know so would prefer escrow be released on delivery and can work with the buyers.


The 3 HP motherboard do not include system/case fans or USB headers, but they complain on boot about those not being installed so require you to hit F1 on boot.
The PSUs are larger than standard size.  They have the same bolt pattern to attach to a frame etc, but are longer.

A little over 2 days left.  The price per Kh/s is leaps and bounds cheaper than a gridseed miner and would make their money back at current rates in less than half the time not counting electricity costs and even at $.10 per kWh would still ROI quicker than a gridseed.

As mentioned they could be consolidated into 2-3 miners to save on electricity or even resell the slower hashing cards and any cards having any stability issues to recoup quicker.

You wanna trade for gridseeds? :)

Also If I bid, how of my own GPU's would I be buying back from you?

miavator,
I would be willing to trade outright for 4 5-chip gridseeds.  I'd cover shipping your direction and you would do the same on the gridseeds.

I believe technically you would be purchasing back 2 working video cards and 1 non-working that I had purchased from you in the past including the gigabyte 7850 :)

4 is a bit steep for a starting bid of 1BTC

3 maybe 3 1/2.

4 is also well under the buy it now :)

But honestly If I could get 3 gridseeds and enough BTC to cover shipping that would be a fair bid!

2 USPS large boxes?  $60 shipping?

I bid that.

Bid accepted I'll structure it like this in case someone wants to bid against it:

3 gridseeds + $60 in btc for shipping = 1.1 btc bid sound fair?

2ish more hours.  I'm guessing miavator is going to win since I believe he has freeish power where gpus still make more sense than gridseeds!

Why would I do such a thing?  After all I'm buying back my own hardware :)
