put your cards as buy it now. ebay has smaller fees for electronics if you post as buy it now. auction has a flat 9% fee. electronics however has a 7% fee for the first $50 and 5% fee for the remaining 50-1000 dollars, and an even small fee for any remaining amount after that. also if you require "immediate payment with buy it now", then 0 feedback users cant do this scam in the first place.

Thanks for the initiative but I won't donate until THEY ask for bitcoin donation.

I think you should hold all the money donated for a month or so and show Wikipedia how much they are missing out. Only pay if the officially setup their own account, otherwise refund everyone and the end.

Only with Stratum?  Someone is sending malformed Stratum packets to that pool, what version and program are you using?
I am not using Stratum. My cgminer versions are 2.7.0 and 2.8.4, between 4 miners on us2.

us2 was probably down today, and after it got back up, my miners were able to connect to it, but it was not acknowledging shares of my miners. I realized it after mobile miners screen was showing 0MH/s for my us2 miners and showed them as down (red) even though my miners were still mining on us2.

Yeah two cores will show up seperately for dual GPU cards.  Seeing as how my 5970s get ~360 each at 810 core, coupled with architectural and clock improvements, this sounds very reasonable to expect (550 per core).

2088  Other / CPU/GPU Bitcoin mining hardware / Re: I have access to several AMD FirePro S10000 cards on: November 23, 2012, 05:07:40 AM
Anyone know the payout of this particular card? I find it hard to find that information on such a new card. I may be able to get several of them. They retail for about $3500 each.



Each S100000 has 2 chips which have same number of shaders as a 7950. One 7950 chip hashes anywhere between 400 - 500 MH/s, depending on clock speed. So an S100000 should hash between 0.9GH/s - 1GH/s. Power consumption should be around 300Watts, with proper cooling. You will be able to mine around 0.3BTC per day at current difficulty, before deducting electricity costs, which could range from anywhere between 0BTC (free elec) to around 0.1BTC (USD $1 - $1.2 / day). To break even at current difficulty and USD 11 / BTC, you will have to mine for atleast 1060 days if your elec is free.

Almost all motherboards will disable onboard graphics if it recognizes a discrete GPU plugged in.  Your motherboard does have the Lucid Universal MVP Support that does allow you to switch between the i7 and the 5830, but I don't believe it actually allows you to use both at the same time.  I think it just picks with GPU would be best used for the current task and runs with that.  I'd read up on that and see if anyone has figured out how to get both running at the same time, but I'm pretty sure you can't do it.

Is Lucid Logic available for Linux? I had the same problem using a radeon 7990 with Ubuntu 12.04, and Z77 graphics. I think it's got something to do with which gpu is primary and which is secondary. I will check my bios settings and let you know.

Starting happening recently? Right after the sun goes down? Could be the solar storm...

I would say the frequency has gone up in the last one week or so. Every morning I wake up with the modem complaining about the excessive CRC errors.
2091  Other / Off-topic / ADSL2+ huge amounts of burst CRC errors (100K+) between 1am and 7am on: November 15, 2012, 03:16:26 AM
I subscribe to a ADSL service, and usually I hardly see any CRC errors but things are the stark opposite at night. There are like 100,000 to 400,000 CRC errors between the aforementioned time frame and throws my modem off whack.

The telephone termination box where the phone company cable is distributed to the house is located near the 'smart' electricity meters. Other than that I have cat5 telephone cable inside the premises. Any ideas or debug tactics would be much appreciated and welcome.
2092  Other / CPU/GPU Bitcoin mining hardware / Re: AMD FirePro S10000 Server Graphics Card on: November 15, 2012, 03:12:17 AM
That's a good point.  I'll look into getting a nice single SC instead of mining my brand new GPU. 

Seeing as how you know so much about BTC mining (ie the change between CPU and GPU mining and how it affected the market), what tips would you give to a brand new miner?

#1: Don't panic. The market WILL go thru some rough patches here and there, esp when both the reward half AND the ASICs hit at about the same time. Uncertainty breeds fear, and fear breeds panic, and panic breeds sell. Just keep chugging along, and when the market stabilizes, you have all those coins to spend.

Good advice!
2093  Other / CPU/GPU Bitcoin mining hardware / Re: Dead 7970 DD Fan Alternative on: November 15, 2012, 03:10:22 AM
I also had a burnt fan with this card, and XFX sent me an entire new cooler, with both fans.

Seems like this card is using very bad quality fans, FirstDo or something, they don't even have a webpage.

How did you contact XFX? I have two of these cards and the fans need constant attention.

Through their support page. You need to register the card with them. I was offered to return them the entire card or have them send the replacement cooler.

Thanks so much for the advice. I will try their support page.

It's disturbing that somebody would suggest a law like this.
It's even more disturbing that the state would actually implement and enforce it.
And it's absolutely shit hilarious how stereotypical it is.

Price reduced from 140 coins to 100 coins



Is the card 100% operational? What happened to the power supply that comes with the card?
Can you do 80BTC? Ship to texas. 1/3rd coins before shipping, and 2/3rd coins on receiving the card.

Looks like it's a pair of 7950 strung together on a single board. It's waaaaay overpriced for mining. I guess these 7990 are more value for money.

The fans on my 7950 (same as this card) just died after one month of use.  That's both fans!  It's a little crappy if you ask me, I think they're using really cheap brushless fans.

Pull them out carefully with a vice http://www.irwin.com/tools/brands/vise-grip

Add some grease and plop them in you should be good to go for a few months. These FirstD fans suck big time and XFX has been using them on all their double Ds.
2100  Bitcoin / Mining speculation / Re: [POLL] Will BFL deliver a Bitforce SC ASIC by October 31, 2012 on: November 05, 2012, 11:47:12 PM
-bump-
Still gonna take a guess and say that they won't be delivering any this October.
So Oct 31 was a no-go for ASIC in the wild. Majority of the voters were correct with their guess. Some best-effort promises were broken. Waiting until Nov 30.
