Ok you're right about the 130,001 I didnt really think that through.

Sadly I will not indulge government coin-destruction scenarios / conspiracy theories, they're best left to the Newbies subforum.

How do the liquid cooled temps compare to the standard vapor pipe cooled ones?

I disagree. I have previously (a few months back) calculated from data on mikaelh's stats webpage that at that time the primecoin network was equivalent to ~130,000 intel Q9550 CPUs (at that time, that was my fastest CPU, and used for comparison).

Now I don't believe that hiring VPS or buying 130,000 x 0.51 = 66300 quad core CPUs is either "cheap" or "realistic" for that matter.

The other thing you might suggest is botnets, except:

i) There is no real evidence that there are even any XPM botnets in the wild
ii) This scenario assumes the botnet operator could collectively control the infected machines to collaboratively work together to perform a 51% attack on the network, when in reality this is unlikely since the goal of a botnet would be to make money as quickly as possible, not to attack and deteriorate a coin

There are probably only a few hundred academics and engineers on the planet who have a complete grasp of the quantum computers / processors currently built. Let alone to comment on the implementation of them for finding primes, let alone primecoin specifically.

Just like any other newly developed high-cost scientific instrument, quantum computers (read D-Wave) will only ever run for academic, military, and government purposes and simulations until their cost falls by orders of magnitude.

There is never going to be a underground group who makes a quantum computer in their basement and starts cracking away at primecoin. Even if that was possible, I can think of a LONG list of things that would make them more wealth before primecoin ever would.

Keep in mind that with any cryptocoin, if there was suddenly an exponential rise in the difficulty from an unknown and unexpected source, then the miners, traders, and investors in that coin would lose confidence over night, it would crash and die in days, and finally be abandoned completely*. This discussion used to come up almost every day here a long time go - before ASIC were around to secure bitcoin - when people were claiming it was a genuine concern that 'some organization / government' would buy datacenters full of GPU just to end bitcoin: there is next to no logic behind it.

Note*: A notable exception / alternative scenario is where some kind of attack takes place but no one cashes out the coins. A good example specifically is the hundreds of thousands or millions of terracoins that were obtained with months of exploitation of the network that have not yet been cashed out. When/if that does happen the coin will most likely die.

Well I'll be taking 30% of that if you are to believe their database:

You can fight over the rest then 

The problem with taking action is that we really don't know how much BTC each person is waiting on, because their database has been screwed up.

Either that or, I have quarter of a million USD of bitcoin waiting to pay out. I really doubt that is likely, because I have always squirreled away any coins from pools as soon as I reached payout thresholds. Unless you were somehow keeping your own records of your mining and expected payouts, I dont see how this would work, and even then that is most likely not evidence that could be used in any legal action.

But things have changed over time: it's much harder to mine coin now. Unless they were taking substantial quantities of BTC offline for storage in the early days of running the pool, then they will no longer be able take a small % as fees to pay back those early miners.

For example, with the recent huge price hike in the market, a lot of old miners like me are logging in to look for old fractions of coins that were 'not worried about' in the past. If 500 users log in to find a total of 20 BTC of mined coins from 2011-2012 (not an unlikely example) then that's $13820 at current market rate the pool operators need to cough up or wait for fees to trickle in. Even if they had 1000's of TH/s of miners, it'd still take a long time for fees of a few % to recover that.

That socket is called a Type E  C19 16 amp IEC socket or also called "15 amp IEC" since they often come with 15/20 amp cable and 15 amp extra-large earth pin here in Australia.

Good electronics enthusiast & parts stores have them, or eBay, or any company specializing in cables. If your region has different sized or designed domestic mains outlets, you can sometimes find these high-amp cables in varieties that allow you to run them off 'normal' designed outlets (with the idea being the load is actually using fewer watts than expected and will NOT cause a fire to start somewhere or blow breakers).

Yes it is definitely a DIY job. I am sorry if I mislead some others thinking you can just pick up a cable to convert it... you can't. There is lots of information and huge forum threads if you just google "hotswap psu pinout" and I can see you've already found some relevant threads.

The detailed way to do it is:

1. Make a strong double shot of espresso
2. Obtain multimeter, soldering iron
3. ....
4. Profit! Power!

I used the modular cables from a friends failed modular PSU to make the leads. It was a just a matter of desoldering the hotswap connector and soldering in the cables. I don't have that setup anymore but it was a IBM (Delta Electronics) PSU 2000 watt I'm pretty sure it was rated to put out over 120 amps 12v DC which should satisfy your needs. To power it on: find a ground pin (via traces) and then short it to all each of the smaller sense pins until it turned on. You could also look carefully at the traces as there are only a handful of them that lead to the 'smart' components of the circuit: most are current carrying for loads and connected to the high power electronic components.

Think I might had a tenth of BTC or two there from really early mining days. Not sure though. I tried to withdraw the balance they claimed I had but it seemed iffy. And of course, I got the generic errors you guys were talking about. It'd be cool if they get the site working and have enough BTC to payout everyone, I remember when Ozcoin was hacked and graet paid out something like 700 BTC with his own funds

Depends on your region. Their designed max load (in watts) varies with your countries line voltage and frequency. They are 2 KW where I live.

This guy says the coin is going to die, lets just pack our bags now and go home guys. It's all over.

Here have my coins

I've started to experience this as well, I have concluded this problem is related to newer drivers (eg 13.xx). I had this card working great with v 12.8 Radeon drivers, as have many others.

Might be time for some counseling, it's been months and you haven't moved on yet.

If you are sure it's PSU woes, and if you are good with electronics, get some $50 used 2000 watt IBM BladeCenter PSU's of eBay and make a breakout adapter for its output terminals. The pinouts of most hot swap PSU are fairly standardized, although it can be worked out 'the hard way' if necessary.

Also, are you enjoying your 10,000 "plz make me 1 dat shiney case" PM's?  

Assuming the fans are both orientated in identical directions, eg  --> and --> then the overall flow will be very slightly improved. I disagree with the comment above that it is actually reducing it: you are creating suction on one end not in fact restricting flow in any way, it is actually enhancing flow through the mid point of the tube.

You can see the same effect with tower CPU coolers that are designed to accept fans mounted on either side. In summary:




The benefit of using the configuration shown in the middle is so small, that usually its not even worth the extra money for a second fan. In all the overclocked rigs I've setup, it usually offers no more than 1-2 degrees C lower temps when under load. I should add though, that the dual-fan configuration is beneficial in case a fan fails: if the single fan dies while you are not paying attention then your miner will possibly get really hot (and maybe burn out, depending on what it is).


Yes, that will help you pass junior grade physics, but in practical small scale applications like this, air density effects make very little difference when it is being forced by fans.

Some SMD components are marked. You'll need a microscope: $15 on ebay or use a laser point lens, a bobby pin and your smartphone camera (ref: reddit.com)

However, such a serious failure usually means that other components have also failed, which either caused the capacitor to fail in the first place, or, were damaged when the capacitor failed.

You are kind of screwed because presumably on such an old card it is well out of warranty, your best bet it to sell it for parts on eBay, someone might still want it (believe it or not) and pay a handful of $ for it, although as that card was never very popular with either gamers or miners your chances here are not great either.

AMD enterprise CPU feature large numbers (4/6/8/12 or more?) of cores which are each usually quite slow compared to intel CPU. Whereas intel focuses on faster cores but seldom more than 4 or 6 physical cores per chip. While it may seem like intel is a 'winner' in terms of performance, its a lot more complex than this: eg. Opterons are usually cheaper than the equivalent intel CPU and sometimes are more efficient. Their high-binned HE (high-efficiency) CPUs are outstanding when comparing operations per Joule (energy efficiency) but as these are creme-of-the-crop dies they cost more.

So no, as long as the CPU is at 100% load, and not being hogged by other programs/services, and is running 64-bit HP miner, then you are getting top performance.

Perhaps intel has a edge over AMD thanks to their on-chip technologies eg. SSE4, however, I think I would have to hand over to mikaelh for that one.

Can you give the string you're using, and the output from the window?

Question the matter (in writing) with the ATO and also request a ruling from them on the matter. They are legally binding (for both you and them)..
