FIRST GROUP BUY:
https://bitcointalk.org/index.php?topic=426359.0


About to start new mining rig, but greedy as f*ck in terms of hardware? I may have solution for You! Atm I have access to 39x SAPPHIRE R9 280X TOXIC OC 3GB DDR5 384-bit cards.

With those beasts You should be able to squeze 750+ Kh/s without any issues.

4 of them I want to buy for myself, but for other I do not have plans since it would be my 2nd rig already. If someone is interested I will be able to get those shiny card/cards for him. Which means there are 35 TOXIC's to get.

Each buyer will receive his own payment adress to avoid mess for me and for him. Make a reservation here in this post + send me PM for reservation confirmation. I am available 16/24h

According to ---> https://bitcointalk.org/index.php?topic=426359.msg4863406#msg4863406 :

Priority:
1. No escrow up to 5 cards
2. No escrow (no limits)
3. Escrow

Q2. "Why?"

In both cases shipping would be via DHL. Can send as a gift(with bigger numbers per user I believe it would be neccessary to send separate packages, so don't panic if U don't get all cards in one package or even day). Ordering only (after all cards are reserved + at least 1 confirm on each payment) OR (4 days after first reservation + payment).   Please allow me 3 additional days to get the cards (need to convert BTC to my local currency). Tracking ID will be send right after I post (Should be minimum 3 days after first reservation+payment, maximum 7 days). Last group buy it was way faster, those dates are pesimistic. Keep in mind I also want to order fast, so it is also in my business to do it smoothly.

Trusted dealer, cards are in STOCK, they are relatively cheap because I get 23% VAT discount on it. ALL cards are BRAND new - sealed!

First 3 cards escrow price is the same as non-escrow. Priority aswell, because I have funds availible to purchase +3 cards from my own pocket.

You may ask - "Do You make profit out of it"? Yes, I am making profit out of it, I still need some to fund part of my 4x cards purchase, and I figured this is the best way to do it.

Price was negotiated already, I don't think I can go lower. Maybe in 10+ purchase I could do 0.01 per card from my own profits..


Feel free to ask any questions regarding me/cards/details/etc.




BONUS! 1 of the cards(I have already choosen a number) will come with free Corsair CS750M PSU!

#3 group buy will be about 50x Sapphire 280x Vapor-x, so if You are still unsure about this group buy #3 groupbuy will start in about 2 weeks, when everything will be done with this one.


Sorry for delay, had to be sure that the cards are availible

4 of them I want to buy for myself, but for other I do not have plans since I am not sure my apartment wall can hold 2 rigs while having a female roommate using all this watt-hungry crap of hers. If someone is interested I will be able to get those shiny card/cards for him. Which means there are 23 TOXIC's to get.

Depending of the success and availability I might be able to get more in the future.

Hello there, for a while I was considering setting up my own rig, but I had no time nor funds to do so. Now I have some spare time and 10th I received my salary. I bought some materials myself, but I still do need graphic cards.

What I do have
 - 2x Corsair 750W Gold+ PSU's
 - MSI Z77A-GD65, Z77
 - Kingston HyperX 2x2GB 1600MHz DDR3 Non-ECC CL9 DIMM XMP
 - PENTIUM G2020 2.9GHz/3MB LGA1155
 - risers, cpu connectors etc

I also did a kettle(yea ) test to check if my apartament can sustain such power drain.

What I do not have and why I do want loan:

- 4x Sapphire Radeon TOXIC R9 280X , 3G GDDR5

I do have them reserved, the moment dealer gets munnies is the moment he sends them

There are 2 options I am willing to repay my debt:
- 30 days contract on my mining rig
- 0.595 BTC

I prefer to take loan here rather than in a bank, beacuse loan at my bank at such low value is 12%, and I think the more bitcoin transactions the better, but I will be forced to do so if I won't find anyone interested.


Cheers

Hello, anyone knows which motherboard can support 4x GPU and does not need shortening the pins, nor using 16x16 risers, but 16x1? And system would detect them all without any issues?

Asus Maximus IV Extreme (has 12v GPU power on MB)
Sandybridge i7 processor
16GB Ram
Watercooled CPU

All of that is overkill, but I just pulled it from my desktop so meh...

Of interesting note, I had to use 16x to 16x risers on 2 of the slots or Windows wouldn't recognize the cards, I don't know why, but it is what it is.  1x to 16x risers on the other 3.

Hey, could You tell me which one will be better? I need to buy 3 of them.

Doesn't longer cables decrease its quality?

Hello I would be interested in 1500W PSU (can't get 1500W one in my country).

PM please (EU preffered coz of import tax)

Hello, will this riser be sufficient for 280x saphire toxic card?

http://www.ebay.com/itm/PCI-E-16X-to-1X-Adapter-Riser-Card-Flex-Extension-Cable-w-Molex-Power-Connector-/181285248039?pt=LH_DefaultDomain_2&hash=item2a35715c27

It has only 2/4 pins, will it be enough? and why?


Also, what is that white marshmallow near to x16 PCI-E slot?


Thank You in advance

Hello, I am considering a setup for a 3x Radeon R9 280x rig, could You suggest me which other parts I should use? To minimize the cost, and be optimal aswell (so the GPU is the bottleneck)?

Assistance from anyone who has similar setup would be even more helpfull

Hello everyone, I am very dumb not to invest in bitcoins earlier.

But lets get to the point, shall we? I've been researching a bitcoin mining for a while, because I want to invest in it, and I am kinda curious how accurate the jumping rates estimations are? What I am especially interested in is - can the jump after this one be like 100% dificculty, or it is unlikely? That is the only thing that keeps me from buying some nasty shiny machine

Thank You in advance for Your reply!
