Bitmain,  any updates on the S2 upgrade option as discussed? A lot of us have paid a high amount of BTC/GHs for these, (at least I) with the understanding we will have options to increase hashing power very soon.

I'm getting ~950GH/s average. The hash rate is always slightly lower on p2pool, but it's worth it, luck has been crazy good lately. If I use it on a centralized pool I get ~1100GH/s using a slightly higher --queue size, but I found using 0 works best on my local node.

Peace  

EDIT: And yes, don't OC it with the standard PSU - it can't take it & you'll be waving bye-bye to it in no time 

Hey there PatMan, out of curiosity, what hashrate does your OC'ed S2 get?  I didn't overclock my S2's because I don't trust the builtin PSU and was wondering if it's worth changing it.

Thanks!

I'm running my S2 OC'd & 212 on a OCZ1250 Gold - sweet as a nut 

Is there a consensus on the best replacement PSU for the S2?   BOTH of mine conked out last night after a power outage.

I was thinking something along the lines of a Corsair AX1200...

Mine "play dead" after power outage too.
But come to life, after I pull the U-shaped wire off the ATX plug for a minute or two.

Cgminer 3.12.0 has been uploaded, https://github.com/bitmaintech/cgminer. The latest version will be updated in 2 weeks.

Hmmmm.......Sorry to quote myself, but the more I think about this - the more it doesn't make any sense. in fact, it smells.

Apart from the obvious legal obligations pointed out by ckolivas, one of the hardest working & well respected Bitcoin community members there is, I find myself wondering why on earth Bitmain won't release their code - are they trying to hide something? I mean, the third party redirect fix was a very important update - why on earth would Bitmain not want to implement it? There are also a multitude of other fixes & improvements which Kano (where is he by the way?) listed in a previous post regarding the S2, but are still relevent:


By not cooperating with the cgminer devs request to release the code as they are legally bound to do - and not updating cgminer to incorporate the very important security fixes, Bitmain are not only breaking the law - but they are also arousing suspicion amongst the Bitcoin community as to why they are refusing to do so. For a company that claims to respect & care deeply for the Bitcoin community, this makes no sense to me whatsoever.

Before anyone starts breaking my balls accusing me of stirring things up trying to discredit Bitmain - I am a customer who has Bitmain hardware & am quite happy with it. I am merely pointing out the legally binding obligations Bitmain are ignoring, as well as trying to highlight the contempt that Bitmain are showing towards ckolivas & kano - without who, mining & Bitcoin would not be what it is today. We, as a community owe it to the cgminer devs to make sure that all hardware manufacturers respect their requests to release their code as stated in the open source license agreement. If they refuse - we should all be concerned as to the reasons why.

Sorry to ramble, but I'm a great believer in Open Source & what the cgminer devs have done, and continue to do. We owe them 

The price is 0.46 BTC.

It's a cool kit but VERY EXPENSIVE. I did some calculations at Bitcoin Wisdom and it will most likely make a tiny, tiny profit of 0.1 BTC or so.
And this is without taking into consideration that the S1 anyway would generate more than that if I leave it running underclocked and undervolted.

Will YOU buy the S1 Upgrade Kit? If so, what is your reasoning?

I must say that it does seem like the S2's were rushed out to use up the old chips while they were already working on the S3, hence the stability issues that will probably never be addressed because now there's a better product out using newer chips.

The one thing that is bothering me the most is that Bitmain is doing their own thing with CGMiner and releases unstable hacked versions on their hardware with no support until Kano takes a look at it. It seems they are having the same issues with the S3 now and CK is getting a little annoyed with them.

I used to hold Bitmain in high esteem, but now I'm distancing myself from the idea that Bitmain is a professional business.

Small debt, pictures with Rock Xie of RockMiner:

Yet YOU willingly gave them money.  They're a business, what do you expect?  I guess in reality none of them should retail sell HW, then people like YOU won't get sucked into the hype and buy HW without undersanding the business you're entering.

Right, guys let's be honest a lot of us don't want admit (that's embarrassing I know) but Spondoolies, Bitmain and others ripped us of.
I know this is Wild West Crypto World still and THEY know they can afford it but how long for yet ?
Someone MUST stop it.
My theory is THEY had those chips long, long time ago. THEY start selling when chips become not that profitable any-more otherwise why they selling ? THEY got huge bitcoin farms, well Bitmain has.
THEY probably already invented and mining with new ones.
Really guys I can not stand it, THEY not support Bitcoin network, they think just about their profits but what nasty way THEY do business ??
Honest business partner should think about future, before they start selling S3 they should start selling upgrade hasboards for S2.

If someone ask me, BITCOIN MINER never again

Yea if that upgrade doesn't come through and isn't affordable a lotta people will get burnt on the s2. I might get 4-5k outta my 8.5k investment at this point.
