Title: Sell my GPUs and Host, or Sell and Ship?
Post by: 1l1l11ll1l on March 13, 2012, 03:56:06 AM
Good evening community. I currently house approx 50 mining rigs. Half have single GPUs (5870's and 6950's), half have 5970's.

I'm 80% full on available power in my server room, and am looking to switch over to FPGA units. As such, I'm looking to sell my GPUs.

Wanted to hear opinions on if I should sell the GPUs and ship them, or if I should sell the GPUs and host them?

I want to sell the GPUs to raise immediate capital to buy FPGA rigs.

  • If I were to sell the GPUs, what % of the mined coins should I charge?
  • Any suggestions on how to monitor and collect the hosting fee?

Thank you and I look forward to hearing your responses!

Each rig only has 1 card?

Yup, Got the systems, complete with an 80+ PSU for $25 each. Add a thumb drive and good to go. They will each support 2 cards, however I would need to buy a bigger PSU.

Compare the cost of even the lowest priced rig that can hold 4 cards? Much better Per Card housing.

Holy shit this is a miner's wet dream. Now if each case had 6 cards each.... :D

There would be a huge fire.

Not bad if the units are dirt cheap. Actually. I know that in bulk you can get units like in bulk of 50 or more for about $30 a unit on a good deal and $50ish on a bad one. Considering they will last psu/cpu/mobo wise for a good while longer with one card, and be pretty efficient on power usage too. Not a bad plan in the big scheme.

Your issue is this.

If the hardware dies, then what? Thats what can ruin you.

That sounds like it. I have problems maintaining my little 2.5 GH farm, yet alone this. Unless we have liquid cooling and good PSU's...

The nice thing is I can get more anytime, there currently is a non stop supply, at least for another 4-5 months. (I love surplus)

Also, since they are all the same machines (dc7600 HP) swapping out PSU and motherboards is a breeze. No tools required for a MB swap, just pop out the tray. HP is also awesome in the config department, I can flash the BIOS to the latest and replicate the bios setup, all inside the bios, and all from 1 64MB thumbdrive. drop my pre burned BAMT USB drive in and good to go.

Down side is the cases do require a prybar to remove the hard drive cage, as the 5970's won't fit with the cage in. Pop the rivets and you're good to go.

There are restarts required here and there, fans to replace on occasion, but the biggest benefit is, if a rig goes down friday night, I'm not eve out a GH for the weekend, whereas my water cooled rig, I'm out 2GH.

Rent out the miners for a locked in price a month?

I'm thinking I'd like to sell the cards, but offer to host them at a % share of the BTC mined. Same as saying "mail your card to me and I'll drop it in a system and set it up"

Mailing You a GPU and letting You host is a nice thought for me. Elaborate, please!
(Electricity, cost structure...)

Or just pay You a fixed fee for one of Your GPU-s and then a % for hosting?

More of Your thoughts, please!  ???

I was thinking of selling the GPUs at a fixed rate (based on ebay prices I suppose) Then hosting for a % of the coins mined. What would a fair % be?

Figure out:

Cost of running the box before GPU
the power of the gpu
10% for maintenance.

Add those up, and would be a very reasonable fee to me.

Sounds correct.

In any case, the base numers are:
Consumption of base sys, of GPU, and the approx. price of electricity by You.
10% plus for support is also fair.

Getting' interested.   :)

How much power does one rig take anyways?

I can't remember exactly, but I want to say somewhere around 3.5amps with a single GPU

Thats without the GPU

Also, I think you should just see if you can rent the GPU's, and after a month or so, sell the remainder that aren't rented.

Honestly, these HP 7600's are all over the god damn place... I have 10 in my garage I got from a local business.

They usually have 350w or 385w PSU's in them. Even at that low wattage they handled 5850's fine. Could be under rated. *shrugs* Unfortunately... I don't have the power @ my place to run all of them. I'm looking into renting a warehouse this summer and getting the heat from what I currently have running gone also.

Good on you 1l1l11ll1l for offering this service tho. 10% of the hashrate per slot sounds fair for those who are in high Electricity places, or can't handle the heat come summer time. Great minds think alike.
