Bitcoin Forum

Was talking to a friend of mine who's heavily into computers and networking and all that fun stuff and we got to talking about bitcoins.
He suggested using at sun sunfire t2000 under linux or unix for it's data crunching capabilies.
looking at specs for the t2000 sees that the cpu is a 8-core, 32-thread 1.4ghz cpu with 16gb of ram and twin 73gb sas hard drives.

Would this work? and if so, what would I see mining wise?

That's what I'm thinking because my friend has his set up as a mysql server under unix, but he seemed to think it'd work because the processor is an 8-core with each core having 32 threads equaling out to something like 256 threads, ment for some serious stable number crunching. I thought I'd ask the opinion here before I go looking for one.

ok - so i'll stop looking for one and stick with my cpu(3ghz single-core Celeron pullin 1.3m/hs) mine for now. Thanks for the help and understanding in this.

The T2000 is mid-2000's server technology. It's been replaced by Intel Xeons in the Sun Fire line a long time ago. Not quite sure if it is weaker than an Atom though - the guy who said it was probably was exaggerating (a little).

No exaggeration: For litecoin the T2  8 core 64SMT processor used in the Sun server has a hashpower of 2,48MHash/s the Atom N270 has 2,57. The OP talks of a server with a is the T1 that is about half the speed of T2. Here's the source: http://wiki.litecoin.net/index.php/Mining_hardware_comparison (http://wiki.litecoin.net/index.php/Mining_hardware_comparison)
If you use it for "normal" data crunching probably will beat the Atom due to the high number of threads (but not of so much), because it has only 1 floating point unit shared by the cores

Why do you even bother? Wasting energy is the most stupid thing. Oh... and dont tell me u want to support bitcoin network. We've heard this crap so many times. You want to protect your country with a knife and a stick, you're still an idiot.

Thanks for reminding me, even though my celeron's pulling 1.3 m/hs, I'm doing really good on btcmine.

Ok so multiple float points determine hash rate also, like the T4(something like 3 or 8 points, I don't remember).

How can you be a 'Hero member'  and not know that you are spending 2 dollars to make 10 cents and tearing up your cpu to do it???????

I'm assuming the fact you said you're mining with a single core 3 GHz Celeron to mean that you are mining with a Celeron D 345.  The 345 uses 73 watts at full load (and not counting power being used by any other PC components).  If you are truly mining at 1.3 mh/second and mine 24x7 for a full month you will make approximate .01 BTC or 13 cents US worth of BTC a month at today's BTC/$ rate.
Assuming you have _awesome_ power rates of .05 cents a kilowatt hour, that CPU is sucking up 1.752 Kilowatt hours/day or 52.56 Kilowatt Hours/month.  At .05 cents/kwh, you are spending $2.62 in electricity costs, so you are mining an making 20x less money than you are spending. Even if you are getting free power, you're pushing your CPU at it's max and hurtling it ever so much quicker towards an early end of life.  I'm with Nemesis, stop wasting your time/power/money.

Not sure, that has to do with either post count or length from start date. I never asked for it.



Intel 3.8ghz Pentium 4 Celeron. There's no D on it anywhere, if it is, it is. I'm not worried about power consumption, desktop doesn't have anything on it but XP pro and bill doesn't get any higher now then it did before I started mining. On that note, not everyone is super rich and can afford a video card good enough for mining, so cpu mining is my only way to go. I'm more then open to accept one to mine, but since I know that'll never happen, I'll stick with what I got.

I like the attitude, but how many BTC do you mine so far?  I mean per what period? Etc academical curiosity.

I mine on and off, nothing ever significant.

Power Used in Watts x Hours in the Day (24) x Days in the Month (28-31) / 1000 (To convert to Kilowatt hours) * Power Cost/kilowatt hour

Just put a bid on a 4350 on listia, it's crap in m/hs but better then cpu mining.

not really.  still only .71 cents in a month...  still spending 4-8 dollars in electricity for .71

Yes well, 10 m/hs is better then 1.3 m/hs, yes?

NO, its not...
and it hasn't been since about june of 2011.
since you obviously have free electricity,  maybe we should make a deal,  i send you cards, you make em run, and i will give you 10% of all hashing.. a couple of 5870's will be over 800Mh.

seriously, dont you get the fact that someone is paying 8 dollars for you to make 10c (71c with new card)....a month?
seriously..  lets call it 50 cents.... a month?  are you in the USA?  drives me crazy....

Aww damn, was so gonna take ya up on that offer, pity I only have one PCIE slot.

Did I break your brain? Awesome. I am in the USA, and while power isn't free to me, I could probly get away with running a few 6990s for a few months before noticing any power increase but since I only have one PCIE slot to play with my options are to get what I can afford or attempt to build a FPGA or a PCIE exter or something.

Ah, you'd be surprised at how quick someone will notice spikes in power usages/bills.  A Radeon 6990 will easily draw 350-400 watts at full load and hash somewhere in the neighborhood of 750 mh/s depending on overclock.  Now assuming you can get a few of them, which will run you $300-$400 each, even for used ones on eBay, two of them in a a hashing machine is going to probably use up 800-900 watts for about 1.5 GH/sec.

Now let's talk to our old buddy math.

If your power rate is 5 cents/kwh (crazy low)
 - (900 Watts * 24 Hours * 30 Days /1000) = 648 Kilowatt/hours * .05 = $32.40 Power Cost.

10 cents/kwh (Low to average US):
 - (900 Watts * 24 Hours * 30 Days /1000) = 648 Kilowatt/hours * .10 = $64.80 Power Cost.

20 cents/kwh (High in most of the US, Low in California)
 - (900 Watts * 24 Hours * 30 Days /1000) = 648 Kilowatt/hours * .20 = $129.60 Power Cost.

None of those are particularly bad because at current rates, you'll be producing about 16 BTC a month worth about $175, making a profit of anywhere from $142 to $45 after you pull out your power costs.  Then again, you still have at least $600 worth of video cards you need to pay off, so in the absolute best case scenario, you're looking at 4.2 months before you even break even. You also can't forget that difficulty will probably go up every two weeks and you'll be making less as time goes on and that 4.2 months could easily stretch out to 5 or 6 months.  And I don't know about you, but I'm sure any landlord/parent/boss is going to notice a $100 jump in a power bill really quick. Finally, if you consider that there's a very good chance that within 2-3 months ASIC's will start arriving and those two 6990's that were producing 16 BTC could very soon only be producing .5-.8 BTC a month while still racking up the same power costs, you might want to rethink _any_ GPU purchase at all. All in all, at least do some calculations to figure out if you are at least making back what you are spending in power with an eye towards the fact that what you are making today will not be what you are making in a month, 3 months or 6 months time.

So we know you pay for power.

And now we know you have an extra hundred a month that "you wouldn't even notice".
Since you have all this extra money, buy yourself a 7970.  you can get almost 3Mh per watt.... 

I think you missed my point. Firstly, My IF I could afford any 6990s, I could run 6 consistently for 6mos before noticing anything in my power bill. Secondly, desktop only has ONE PCIE slot so unless I can magically make a port extender appear, I'd only be able to run one card of any card I can afford.

I never said I could afford 6990s, but with what they pull, I know what the system here at the house can handle.

Instead of getting that T 2000,on ebay they go for $265-1000 on average:

Take that cash & get a couple of Jalapenos  8)

not that i'm aware of... this origionaly started out as a discussion wither or not a certain unit could mine since it has a 32-process set up but the knowledigle people in the thread pointed out that it wasn't possible based on the chip having one floating point. It's been alot of back and forth either by people who don't know what their talking about, judge me by my past, or try to rile me up so I explode and leave. I was honestly trying to get feedback about using a unit to mine.

I was thinking of doing that also, since the single looks really good right about now.

I've been tempted to, but if what's true of bfl, preodering won't be worth it. I still might just go build me a FPGA and mine from that.
Trying to pester a few folks for their board designs and how where they got parts/board fabications/etc...

well I was looking at eldentyrell's fpga and thought that would be a good base if there was a way to increase the hash rate, and except for the spartan 6 and the pcb, I have the other parts lying around somewhere.

dang it - I was just browsing the list of stuff my pick supplier has and he's got a bunch of spartan 6 chips >.<
I'd go get one if I had the money to or could get a loan to do so.

EDIT: I made up a loan request on BTCJam for one. Here's hoping it's fulfilled.

I don't, but the owner of the house lets me see the bill.

A bit late, but if you actually want to pull something like this it would be better to tell the owner to give you $5 each month. That way you don't have to spend say $10 of the owner's money to get 80 cents of your own. Win-win!

Try posting on the lending board and you might get more people to loan you moneys.
