Mining at 7566.57 MH/s... should I go solo, etc?

[bahnfire]

Hi All,
I am currently mining >7500 MH/s (on a pool) and would like to know if this kind of setup is better solo or with certain pools. I plan on expanding this to >10000MH/s by the end of next week.
Thank You,
Paul

you'll average a block every 29 hours.

why on earth wouldn't you mine solo?

[Basiley]

sure. "only" ~50 bigger farm and you can get serious Hardware utilisation, finally.

[allinvain]

Holy christ what kind of hardware you have dude?

[error]

If you really have 7.5Ghash/sec there's little point to being in a public pool.

If you mistyped, and have 7.5Mhash/sec, then you shouldn't be mining at all.

you'll average a block every 29 hours.

Nope. 2**32*244139/7567e6/3600 = a block every ~38 hours.

if the (old) Bitcoin Calculator is wrong, then it's wrong.  but that's what it says for 10 Gh/s.

Hi I'm new to bitcoin and have many things to learn, may I know how you guys come up with these figures ? I'll soon be expanding my mining capacity too and would like to know at which point in the future should I consider mining solo and why.

try these two:

but mostly, just read the mining sub-forum.  every day.  over and over...

We are both right. I quoted numbers for 7567 Mh/s. For 10 Gh/s it is indeed ~29 hours.

ah, of course.  sorry - my mind was busy being boggled by the idea of 10Gh/s in my living room...

By definition, at difficulty 1 you must hash an average of ~4 billion blocks (exactly 2**32) to solve one.
So at the current difficulty of 244139, you have hash 2**32*244139 blocks. Just divide this by you hashing rate to find how long it would take to solve one.

No, it's really 7500MH/s. I am running 6x machines with 2x 6990s in each machine and I plan on expanding to 4 more machines next week. The hard part is keeping them cool enough - so I am moving them to a facility that has a good A/C and enough power (each machine takes ~10A @ 110V).

I will try solo mining since I am only at ~15BTC/24 hour period.

Thank You,
Paul

even minus 2% for slush's pool, with 7.5 Gh/s running pooled, you should be somewhere around 30BTC/day...

[bahnfire]

Hmm... I will need to recalc this then. Any difference between slush/deepbit/etc? I will need to run the system for another 24-48 hours to get a better baseline.

with 12 6990s, you should be getting about 9 Gh/s already - that's at 750 Mh/s each.

what are your boxes made out of?  OS, mining program, etc...

[bahnfire]

I am on BIOS position #2 (standard) due to heat concerns and crashing - so I am getting around 300MH/s per GPU (4 GPUs/PC * 6 = 7200MH/s). One of my machines is watercooled and I have that one set fairly high (~400MH/s). I am using an Asus Mboard w/ 2x PCIe, AMD Phenom x4, 1GB RAM, 32GB HDD, 1600W PSU, 2x XFX 6990s, and Windows 7 (64 bit). The water cooled PC is using Koolance blocks and reservoir and has a 4x PCIe MBoard (it will have 4x cards in it soon running Linux, waiting on other 2x cards for this one - the other 8 cards for are in the garage waiting to be assembled).

I am using GUIMINER since I needed something quick to test and play with.

Quick question - do you need the crossfire cable connected between the 2x cards? Any advantage to this vs not? (Going to bed soon - will check posts in morning)

Thank You,
Paul

Question - why does common concensus seem to be that he should go and mine solo wiht 7.5 Ghash/sec?

It's not like his volatility doesn't lessen a ton like most of the rest of us, and a even a 2% fee (there are several with lesser fees) isn't a huge cut. Why wouldn't he want to mine in a pool?

because the main reason to mine a pool is to even out variability.

with that kind of Gigahashage, he has no variability to speak of.

[Clavulanic]

Wow... You have 12 6990's and only get 7.5ghash/s?? Holy crap dude, and they are overheating? And you're on a pool?
Seems like every day someone rushes headstrong into mining without thinking things through or fine tuning their operation.

My other observation around this forum is that a lot of people really don't know much about hardware, cooling, systems and that general area. Even the smartest bitcoiner may not be proficient in this area.I'd suggest browsing some PC forums to learn in this area. Overclock.net and xtremesystems are probably some of the better places. *Yes I know OCN is shit with the retarded ass moderators, BUT there is still a lot of information there by a lot of great MEMBERS (not moderators).
