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.

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

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.

Thank You,
Paul

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...

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...

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.

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.

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

We are both right. I quoted numbers for 7567 Mh/s. For 10Gh/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...

you'll average a block every 29 hours.

why on earth wouldn't you mine solo?

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

try these two:

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

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.

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
