^how do you actually get that low? I can't go below 1250 mem on my 290s using afterburner.
Have you tried undervolting in AB at all?

I'm not 100% sure I understand the soft fork vs hard fork but from what I think I understand the hard fork seems the most logical to me. The hard fork would reverse the wrong doing and at the same time prevent that exploit from happening again by fixing the system code. The soft fork does neither of these?
I'm in the same boat. If someone knows could you explain the differences and consequences of hard vs soft fork?

Sure. As I best understand it:
Soft Fork- The Dark DAO is basically blacklisted and cannot trade with any other addresses (except maybe a Robin Hood DAO that is whitelisted to attack it and take the ETH back). This is accomplished via updates to geth and wallet software so that way its a pretty painless transition. Most of the opposition are people who want to do nothing because they love Bitcoin's anarchy
Hard Fork- A whole new blockchain is created and miners move to that blockchain instead of the old one. In that blockchain the old DAO doesn't exist anymore and is turned into a simple contract by brute force, and all the ETH in the dark DAO is moved to this simple contract by brute force. A hard fork is basically what will happen when we move to POS- the old blockchain (with the normal DAO and dark DAO) will still exist until 51% of miners move to the new one and its not viable anymore. Most of the opposition are people who feel it sets a bad precedent to rollback a transaction.
Personally I don't think the hard fork is needed. I think the soft fork will do enough to get most of the DAO back, it just might take months instead of overnight as the locked up dark DAO is slowly drained hack by hack. Seeing as how the hard fork could really split the community (ESPECIALLY if the owners of the Dark DAO bribes miners to continue on the old chain like has been suggested) its a big risk, while a soft fork would be pretty seamless. That is all my opinion though.

http://www.techworld.com/security/e...bes-night-crypto-currency-was-hacked-3642315/“So now the money is in a bunch of different places, controlled by a bunch of different people and we are now approaching this point where we can do a minor alteration to the software or it’s going to become essentially a game of I drain your DAO, you drain my DAO so that no one can ever drain the money and this stalemate has occurred and we still aren’t sure how this will be resolved.”
“The question we are faced with is whether we revert or not, should we set it right? I think that the network should set it right. It is such a terrible failure to lose something like ten percent of the ether in existence to one individual that it could potentially threaten the project. I think we are in the first year and it is a reasonable thing to do. It has been done before and hasn’t grossly effected how bitcoin operates.”
But does the soft fork prevent this type of occurrence from happening in the future?
Seems like eth has bounced back in value to around $14 USD. A good sign.
Interesting, I can get 25 MH/s @ ~150W with a 290. So 24 MH/s @ ~100W would be an improvement. If there were a better selection of reliable 6-slot PCIe boards out there, mass-buying 480s would be a good play. Makes you wonder what the 470 can do?
Also, nanopool.org is now letting people vote on the soft fork by "voting with their hash power". They are not voting on the hard fork, and the people running nanopool seem hostile to the idea of the hard fork.
Personally I think that if they are going to do any fork at all, they might need to go all the way, but what do I know . . .
So I'm conflicted as to what to do? I certainly don't want to vote "no" and just leave things as they are, but I'd rather support the hard fork? Not sure if they will have another round of voting for that option?
FYI here is another writeup on the options that is pro-Hard Fork so I don't come off as biased:

I have read somewhere that 1125 is the best for memory on Hawaii to optimize the timings.
Do you have extended overclocking limits enabled?
There's no single memory speed that's best as it depends on your goals (raw speed vs power efficiency or a balance of the two). It's mostly dependent on the set GPU speed and type and memory timings (to a lesser extent).
I use GPU-Z to monitor the memory bandwidth and tweak accordingly speeds accordingly.

The hacks pose an existential threat not only to The DAO but to the entire Ethereum currency. To avert the crisis, Ethereum officials have proposed rolling back the blockchain in a way that would invalidate the stolen ether. Such a "soft fork" of the Ethereum protocol would have to be approved by 51 percent of Ethereum miners in the form of a software update they would install on their servers. Ethereum founder Vitalik Buterin has said he supports such a plan, but in the same statement, he also recognized it would have to be supported by a majority of the miners, meaning it's out of his hands.
The proposal has set off howls of dissent among some Ethereum proponents. They point out that Ethereum was designed to work with its own dedicated programming languages that allow it to work seamlessly with "smart contracts." Such software-driven contracts allow for the automatic payment of funds when a set of detailed conditions are met. Fork opponents say the entire appeal of Ethereum is its decentralized nature that by design is supposed to be immune to control by banks, governments, or other powerful groups.
I don't really feel like Slock.it is unbiased... they made the DAO. Plenty of people on either side that actually don't have a stake in it.
basically, a flaw in the exchange made it so crooks got 50 million so far...and they can't fix the bug.
So, doesn't that mean that this cryptocurrency is about to take a nosedive?
Nah, its just a flaw in the smart contract of the DAO. The technology of Ethereum is fine, just this one contract (made by Slock it and not the Ethereum foundation) was crap.
There is some debate that the abstraction layer itself has a flaw, but that can be fixed.
