Actually with the ram and Xeon etc... the machines take a bigger bite of crypto and with an on board memory controller the work load is huge. = more coin

Careful when you crank them to the max they get super hot and blow cards. EASY!!!
Got 6 bad/fried R9 290X cards on RMA

Those are not R9 290X cards, they are just R9 290s

Wow!! :1orglaugh:1orglaugh

Open with a huge fan has been the best way. When I say these thuings get hot, it's an understatement. Some cards run at almost 90c, I've kept mine under 81c

From what I understand of the proof of work involved with Scrypt, that is not the case. What are your hash rates per card? I'd venture to say that they are very near someone using a Sempron 145 and 2GB of RAM. You can likely save yourself a lot of money by not buying unnecessary components. Ask yourself: if everyone else is doing something one way, and I'm breaking that trend, is it because I figured out a better way, or because I'm wrong?


I run mine at 45% fan and 75C-80C, so that they can last for years without issues. In a datacenter, the environment is VERY different than at home -- the cold aisle / hot aisle cooling keeps my cards nice and chilly, the fans just move a bit of air across the surface components.


He doesn't even understand the difference between what he posted and the R9 290's in my rigs, how can you expect him to understand model numbers? There's a reason those who can do, and those who can't troll. It's a lost cause. :1orglaugh

Yeah, sad that he'd think that ... but you can't expect everyone to know that a TV isn't the same just because it's the same size, LOL .. or a car isn't the same just because they both have four wheels. Some cards are good for gaming, some are good for mining .. if you don't know the difference (or why, and what to modify on the cards to make them perform and be maintainable), you'll just cost yourself money over time. Or, like that guy (I don't recall his name), you'll just sit on the sidelines thinking you know shit, haha.


Hot aisle / cold aisle is an excellent cooling method -- the de facto for most of the big boys here in FL. You obviously shouldn't be running these from your house, so no data center nowadays shouldn't be able to accommodate your needs.

Yikes, I just noticed what you're mounted on. Be VERY careful with static build-up. Aluminum is better all around, with static-dissipation properties being just one factor.

So nobody lose when trading?
I thought for someone to earn in trading someone has to lose. Apparently losing is not possible... :thumbsup

His implication (through his lack of understanding) was that the value of the currency somehow affected me or even mattered. As a market-maker, I make money regardless of whether the trade is up or down.

fid for sal\\

But you also mine a lot of stuff so coin price affects your bottom line.

holy crap Edge. When we did it which was less then half it was so fucking hot in the room I thought the FBI would raid it thinking we had a grow house LOL.
You are really in this big time. Very cool

Only if you have a shitty understanding of mining. As prices fall, competition decreases, which lowers the overall difficulty. I mine more coins during these periods, more reliably, which turns into the same or more money. Alternatively, you mine more coins with less competition, then sell them later, which is a very large multiple (this is often what I do with mining proceeds during downturns).

For me personally, since some of my equipment is on contract, I make money no matter what the price.

And that is why I chuckle at the "so far off base, they're not even in the same ballpark" attempts to troll. I only even bother to respond to them so other less-informed people don't take the words of fools as gospel.

Indeed. For security and cooling reasons, my rigs are in data centers. I'd never run them in my house, that's amateur-hour. Asking for someone to either come rob you or for a fire to start.

At my mining center I have a 48 inch exhaust fan pulling 23,000 CFM through the miners and out of the room. Keeps things very cool. No cooling just heat removal. (Cheap)

BTW, you can flash this 290 to an 290X easy.

To the bios, yes, but not all 290 cards had 290X components. It was actually a small number of them, and is a big reason I can get such a good price for mine.

I'm curious what the average amount of dogecoin mined in a day with the current difficulty and using just one of those 290 cards.

ROI is what I'm curious about.

How are your cards different?

And he is selling R9 290s

I just switched over to mining Scrypt-N. I get about half the hashrate, but still experimenting. There is some difficulty getting each machine running smoothly. That seems to be discouraging some miners. I have found that in some rigs, I need a little more board memory to get the cards to work properly. Definitely making more money though. You really have to experiment to get your hashrate up, there is no one size fits all.

The cards he appears to be talked about are the ones I offered to keys -- those are 290X cards in 290 clothing. The cards he posted in comparison are true 290's. The manufacturing process that used 290X components is long over with. Early on, there was a shortage of 290 components, so manufacturers used 290X components in the 290 cards. When flashed to the 290X bios, the full power of a 290X card is unlocked. This was a VERY SMALL portion of the 290 cards, and only those who carefully researched and purchased were able to get them.

What I'm asking in this thread, however, is where people who sell rigs and components sell them. I'm interested in having my tech build 290X rigs and then resell them at a profit (my volume gets me favorable pricing), but I am unsure of the channel to do so. eBay sounds iffy, so far, is what I've gotten. Sadly, those who know the least know it the loudest, so any good information has kind of been drowned out by "hurr hurr buttcoinsssss". But hey -- GFY.

Yes, the money was great when I switched a while back, and is still damn good now. The technical-know-how barrier to entry is pleasantly high. Also, with the ASIC resistance that Scrypt-N provides, I can keep my GPU farm on that and put the Titans on DOGE, etc, when they get here.

The new scrypt ASIC miners are what caused me to switch to Scrypt-N. I ordered a Gridseed to play around with. It mines BTC and Litecoin simultaneously. When the others hit the market, which will be soon, it is going to change the GPU situation a lot and push a lot of miners to Scrypt-N. Don't know what to expect. I suppose a lot of coin devs will be real busy. At any rate, it's very interesting to fuck around with and even more interesting to be able to make money doing it.

For sure. Check out the Titans. Order 10 if you can, it's worth the gamble of them not being delivered. $9,995 gets you 250 Mh/s. For under $100k, you're at 2.5 Gh/s on Scrypt. That's amazing for price-per-hash. Oh, and about 4-4.5 amps on a 208V circuit to boot. That means that all 10 Titans can fit on a pair of 30A 208V drops in a data center. It's going to be insane. I can't wait for mine to get here.

yoiu're so fucking full of shit :1orglaugh

loser

Nice well-thought-out rebuttal. Sadly, everything I am saying is easily Google'd. You're just not that interesting, sorry.
