I have three Powercolor 6990 with EK waterblocks pre-installed that I would be willing to part ways with. They are less than a month purchased and been mining for about over 2 weeks now. PM me if you want them

I am really confused. I always thought mining in a pool means all the participants are sharing their computing power towards finding a common block and that the pool server will send out to each worker a "piece of the puzzle" to solve & and solo mining you have to solve everything yourself. Is it correct to assume if you found a block in a pool over a certain period of time that you would also find a block by solo mining? I have 3.2g/hash in a pool right now for about 2 weeks and have only found 1 block according to the pool stats.

This is brand new, still in the sealed box from the factory. Its the full package with all the blocks, connectors, tubing, coolant.

Here is a link to all the info

I bought two with the intention of cooling  two 3x 6990 rigs, but I ultimately stuck with just one rig, so now I have no use for the second cooler. I am currently using it to run 3x 6990s, granted it runs a little hot and has a few fans pointing at it, but if your water cooling needs are a little more reasonable than 3x 6990s, this is a great setup. It runs totally silent - zero sound. Very easy to setup and a very nice to look at if you ask me

Ill let it go for $199 + shipping cost. Paypal please

Tried to do a search on which one of these cards runs the coolest (excluding water cooled and the ones that take up three slots) but I can't find any reliable info. I know all these cards are the same, but anyone have any idea on if the more expensive ones with more fancy shmancy looking fans are actually worth the extra money? I plan on running 4 in one rig so I would be willing to pay a bit more for colder card, but I would rather not waste money if the more expensive cards are just a sham.

  thats kind of a drool ? haha

Ive been ask for some photos so I will just post them here for all to see also.

These are straight from Newegg. Powercolor Radeon HD 6990 cards. Brand new, in wrapping, untouched. Full warranty and Newegg receipt will be included. I bought 6 and made myself a 3x6990 rig. Runs great, water blocks flow well, I get about 405 mhash per core (so over 800 for each card) with no modifications and running a straight Phoenix miner with GUIminer. My plan was to make two of these rigs, but I just don't have the space so I am going to sell the three untouched cards. You can buy one, two or all three.

Here is the product page:

MSRP and price I paid was $899. I will ask for that same back, not looking to profit of these 6990s

Insured shipping within USA is included for free.

I accept paypal only, I have several thousand verified paypal transactions for your security.

Please feel free to PM any questions or inquiries

So i wait for weeks, i finally am at the right place at the right time for the nowinstock notification where I get my order in for 2 6990's seconds from getting the notification. Credit card charged, packaged sent. I open the box and BOOM: 2 6970s in the box. Called newegg. Nothing they can do but say sorry and give me a refund. Sucks!

I will be happy to provide a side by side comparison for the following step up

3x6990 water cooled linux v windows. I am building identical rigs and will put windows 7 on one machine and ubuntu on the other. I know I know water cooling is lame/not profitable etc etc but I am really just in this bitcoin gig for fun and if I break even on costs in 1 year I will be more than happy, and its fun to play along even if I never break even. All the parts are in shipment.

bitcoin value will really decide this

anyone know when the 7000s series are coming out?

Excellent tutorial, thank you

I would like freedom to the forums beyond! I have been reading this forum a lot of the past two weeks and would like access to hardware subcategory so I can further participate and get some help with my intention to build a nice 6990 rig for enthusiast mining purposes.

Hello all , I am certainly a noob. I have been reading a lot of this forum for the past several weeks so I think I have learned a thing or two. I currently just am mining with a few simple computers churning out a whopping 100 Mhash/sec. I have no confusion about hitting a jackpot here and building a mining rig to retire on, but I do appreciate the entire concept of bitcoin and I want to participate while at the same time find an excuse to buy a bunch of video cards and build computers and participate in this community - we all need hobbies!

I figure if I am going to get in, get in right! I intend to get 3 6990 when they come in stock (i know, super hard to find) and build a decent rig out of those hoping to get to 2 Ghash as an output. I do not pay electric costs. Anyone recommend a good motherboard/PSU/case for this purpose?

Thanks!
