Why so many orphaned blocks on ypool?

Estimated CPD: 15.6273, Average CPD:  0.0000, Mining time: 00:44

Estimates 15 CPDs wiht 10.0v but reality is much much less. I didnt want to wait longer but yesterday it was running for 9 hours and I got like 1 CPD on average.

CPU single-core AMD sempron 145 2,8 GHz, -ss 3, 3x 280x cards. With 9.1 everything works fine, I get ca 14 CPD.

Some problems with v10. With i5 CPU and 3 280x everything works fine, I get 16 CPD. But with AMD Sempron single core processor and 3 280x very few share only found. It estimates 15 CPD but reality is more like 1.5 with 10.0v. Same rig estimates and averages 14 CPD with 9.1, so I switched back to 9.1v.

No point mining then, it is better to just buy if you believe that price will increase.

How much 280x earns btc per day mining sync at the moment? Is there a calculator somewhere?

Keed up good fight Mad.

Any hopes to get something running in couple hours?

IP changes when you restart router without static? For me it usually runs for months straight.

Are those coin that have been mined already still eventually reach my wallet?

Rollback driver and you're good?!

I updated driver to 14.4 same error.

I have i5-2400 @ 3.10 GHz. This rig crashes.

It is working on my other rigs with 13.2. And it shows 11.5 CPD for 3 card rig with 1080/1250. With cpuload="0".

It crashes.
Sometimes it has several rows of error: ProbablePrimeChainTestFast 0/4. Like 20 or so. On two other rigs I have pretty much all same except processors are Sempron 145 and this rig has i5. And I use this rig for gaming and stuff also, so maybe there is some kind of other issues.

I will try driver update later.

I have win7, 13.2 driver and I clocked both mem and core to 1000. 280x. Restart and still same error. I know newer driver should be installed but I got the same software setup on other rigs and it works fine.

You can tell by ypool past 48 hours connected workers graph that some people switch rigs of during day around US timezones. I guess people in GER, NED and such don't mine anymore because it can't be profitable unless you steal electricity.

It is already pointless to mine scrypt with GPU and lot of them switch to alternatives.

Less than what? How you calculate what it should be.

It seems that people still don't get probability.

Good example are my 3 GPUs. Now they have been running for 3 days straight and still there is twofold difference in average and estimated CPD. It mean that one card has earned me twice as much on ypool than other. It is tottally pointless to make conclusions after couple of days or even weeks.

I got 2 rigs with three 280X cards, single core AMD Sempron 145 processor. 115k 4ch. Both 1000W Chieftec PSU. So, combined 6 cards take around 1200W, around 150W per card. It is half what scrypt uses and cards are way cooler.

I know what you are thinking, did I get zero or three blocks last day. So, do you feel lucky, punk?! Do you, feel lucky?!

By gravity and typing I ment that if you don't believe in gravity then you pretty much get killed pretty fast because you fall of a building or something because gravity is there and will pull you to earth. Ouch! Other option is that there is actually no gravity. It mean that you would fly into space. Either way If you don't believe in gravity, you are not alive to type this message.

I don't understand what is the problem with ypool. Stable and fair income - over period of two weeks I got pretty much as if I would have done this solo. First I got twice as much blocks but lately I get less. Either solo miners haven't heard about theory of probability or those punks feel extremely lucky. Are you trying to beat math? Try casino - with this luck you should be millionaire in 10 roulette spins. You type here, therefore you at least believe in gravity, don't you?

I think it crashes because you have two cards on board and when you overclock them,  they overheat or something.


It would be a waste of time. These card dont break even anymore. Better work on cards that really earn something.
