Title: [WTT] Bitfury v1.2 h-card based rigs for v2.3 h-card rigs DELETE PLEASE
Post by: allinvain on February 25, 2014, 02:44:17 PM
This might be a longshot but is there anyone who wants to trade bitfury v1.2 h-card based rigs for v2.3 h-card based rigs (the PCIe style ones)?  I am also open to a swap for other hardware like kncminer jupiter, etc.

The reason I am doing this is that lately I do not have the time necessary to muck around with these rigs. They sometimes freak out and demand some attention. For example being that these rigs are pencil modded after a while the overclock increases over time by itself to the point where a card may be running to fast so hashrate drops. This is when you have to step in and re-modd it down a bit. Once you do this you're all set for a while.

From my understanding v1.2 cards can be pushed pretty far if you know what you are doing. I personally would prefer the lower hashrate but more stability of the stock v2.3 h-cards.

I have a few of these rigs, all with heatsinks already attached. Here is a summary of the bitfury gear I have:

ONE 16 h-card rig (runs at ~500 GH pencil modded - could be better if you are better at modding it than me or replace the resistor)
TWO 12 h-card rigs (runs at ~380 to 390 GH)
ONE 8 h-card rig (runs at 250 GH)

I have aluminum Sportwood open air cases for all except the 8 h-card rig but of course I'd give you the case only if you trade in some other hardware for it.

I'm open to offers or ideas either here or via PM.

I just want those cases! I am trying not to hound Spotswood to do another run of making them, but I really need 2.

lol, I had to hound him and wait quite a long time to get them. They are pretty nice though. Sadly though, if I give you the cases I'd have nowhere to put the rigs. The only way I could do that is if I replaced the bitfury gear with something totally different - ie, KNC, CoinTerra, HashFast, etc gear.

I bought a 10 card V1 rig from goxed with server heatsinks attached. They run great, average about 358 GH/s on eligius. I saw on the bitfurystrikesback webpage they are selling aluminum heatsinks that utilize the screw holes in the V2 boards.

That may help you get some more out of the V2 cards.

Good luck on the trade!

Well, I got heatsinks ready for the cards. The ones BFSB is selling are expensive but they're very nice and I like the mounting option - far better than the glue-on type I'm using, but so far I haven't had any fall off. Some have sort of came loose a bit as the thermal glue weakened but it only happened to a few of them.

I'm going to close this thread. I am just going to sell the v1.2 rigs a little while from now.
