961  Bitcoin / Mining / Re: The TRUTH on: June 19, 2011, 09:09:35 PM
lol, it was anything but the truth. The fact is ALL mtgox account has been compromised, and at least a few people lost money.


Nice try.

What these means in front of card model: HD, EAH and AX (tried search but didn't find answer i was looking)

They are just manufacturer codes, they aren't significant.

For example Asus ATI/AMD cards are in the format ASUS EAH6950 (E: PCI-E, A: ATI/AMD, H6950: Model HD 6950),
and Asus Nvidia cards are in the format ASUS ENGTX 580 (PCI-E, Nvidia, GTX-series, 580: Model GTX 580)

To find out if your card is reference, look at the amount of memory and the cooler. If it has a DirectCU II cooler for example and is overclocked in the factory, it's not reference.

All reference cards look alike but have different stickers on them.
Reference 6950's for instance always have 2GB of memory, a single blower fan on the right side of the card, and a dual-BIOS switch.

You can use PCI-e 1x, 4x, 8x, 16x! It's all the same for mining! You can even use PCI slots with adapters found here
http://www.cablesaurus.com/


BTW, Thank you for the tip! Wink

That's not possible. I don't think a normal PCI slot even supplies adequate voltage for a PCI-e card.

It would be impossible to get the card to boot through an adapter.

You need at least a pci-e x1 slot.

Their market position is huge so they really can roll back the price.

Other exchanges will follow the price like puppies, just check bitcoincharts.com when Mt. Gox opens again.
965  Other / Obsolete (buying) / Re: wtb $5k mtgox usd asap. need high rating. on: June 19, 2011, 07:18:07 PM
They rolled back all the purchases made at 0.01 because an account with tons of BTC was hacked. No get rich quick chances.

Check Mtgox.com
966  Economy / Economics / Re: trade should be cancelled on: June 19, 2011, 07:15:19 PM
Well, it was too good to be true. Thought I really made $250,000 in 1 day by amazing luck.

Understandable decision though, looking forward to seeing the market open again.
967  Bitcoin / Mining / Re: Block 131882 only made coins on: June 19, 2011, 06:07:44 PM
That's nothing. I saw a 3 second round on slush a few weeks back. Didn't manage to slip in a share so no reward though.
968  Economy / Economics / Re: seriously... on: June 19, 2011, 06:00:17 PM
Hoping Mt. Gox doesn't reverse the funds or that they weren't hacked

Bought a metric ton at a cent each
969  Economy / Economics / Re: Marginal value of a bitcoin on: June 19, 2011, 05:11:32 PM
If I were just looking at bitcoins as an outsider, not knowing a thing about mining etc.. I'd probably pay around 20 bucks each because they are quite abudant at the moment.

Maybe up to 50 bucks if fiat currencies start sinking in relation to gold/silver, and crash due to an economic crisis etc.

$1000+? Not in this lifetime without a very good reason. (Like the devaluation of dollars)
970  Other / CPU/GPU Bitcoin mining hardware / Re: The new 6950 from Sapphire on: June 19, 2011, 05:07:25 PM
Thanx for the gr8 reponses to my post.

I never nkew how fast these cards are for mining esp when unlocked.

Question is finding the cheapest 1 in UK as they're pricier than in the US but would customs tax takeaway hte savings I'd make by buying it from US or not.

If you can help me find cheapest one thats whether its new in Uk or used on Ebay thats working I can save quite a bit.

That's be gr8

Thank you  Smiley

Tried plenty of retailers, small shops and price comparison sites, overclockers.uk has the best rate at 179£ per card.

http://overclockers.co.uk/showproduct.php?prodid=GX-194-XF

Then again, they have a this week- only exclusive offer for the 5850 xtreme for 116 pounds. I'd buy some if I were you.
http://overclockers.co.uk/showproduct.php?prodid=GX-259-SP

Can vouch for the 5850, have 4 of them in my rigs. Very quiet and they run cool. Output easily 310-320+ mhash/s at modest OC
971  Economy / Economics / Re: Success with donation addresses in signatures on: June 19, 2011, 04:59:17 PM
It seems like cheap begging, never understood the point of putting one in a signature. It's not like 99.9 people will recieve anything.

Then again, I do waste a lot of BTC sending money to people's wallets here on the forums if they post something funny or valuable.

Sent almost 1.5btc this week, lol. I mostly send random 0.05 donations.
972  Economy / Economics / Re: What is holding you from investing tons of money in this? on: June 19, 2011, 04:56:47 PM
Nothing. I already poured literally tons in "this".

Then again it's paid off a long time ago thanks to the sudden price increases around May.

Why bother running SETI/F@H at the same time with a bitcoin client?

I hope you are only utilizing idle cpu cycles, not GPU..
Even then it *could* increase the number of stales

Quote from: new_in_this
and what GPUs i should chose? Also is my 750W PSU good enough?

5830s, 5850's, even cheap 5770s if you can get your hands on them. They're mostly out of stock though.

The next best thing would be a 6950 unlocked into 6970, great price/performance ratio.
A quality 750W psu will easily run 2/3 of any of the above GPUs.

Radeon 6990 has the advantage that you can put two of them in most motherboards & get 4 gpus, without having to buy two computers with 2 gpus each.
So it's actually a bargain and a great card for bitcoin mining.
974  Other / CPU/GPU Bitcoin mining hardware / Re: New bitcoin machine: To buy or not to buy? on: June 19, 2011, 04:45:52 PM
That'll bump me up to 1.2 GHash/sec, because it's coming with two 6970's in a Crosshair V attached to a Corsair AX850,

hi how do you get 1.2 ghash with 2x 6970?

Liquid nitrogen, overclock the cores to 1.6ghz each, install dry ice supply under the VRM.

The point is that he is prob. keeping his old rig so he has 3x6970.
975  Bitcoin / Mining / Re: dual 6990 ~1400mhash -> solo or pool? on: June 19, 2011, 04:36:47 PM
DB has no confirmation period for payouts and very low variance due to the high hashrate (~3thash/s), though.
976  Other / Obsolete (selling) / Re: Selling Mining Rig with 2x 5850's for BTC on: June 19, 2011, 04:34:37 PM
That's because we own identical rigs...

Now, do you have any legit questions or are you here to troll?

Why did you only change 2x dummy plugs to 1x, and 4x case fans to 6?
977  Other / Obsolete (selling) / Re: Last Chance: North Korean Notes 4 sale on: June 19, 2011, 04:30:40 PM
I'm interested in post-2009 notes which are extremely hard to obtain.

Previous ones have been smuggled and stolen massively from NK banks in full bundles by officials and diplomats after the devaluation
so they are not of particularly high value anymore even as collectibles.

If you have new series notes (stamped 2009+) with Kim Il-Sung's picture I will pay up to 2BTC per piece.
978  Other / Obsolete (buying) / Re: Buying 6.39 Bitcoins for $17.50 each on: June 19, 2011, 04:20:53 PM
Looks like trash Wink I cant trust a site these days unless its looks professionally made.

Mt. Gox looks like crap and they deal in millions of dollars weekly.

It's good against DDoS; With no excess of images or pointless flash animations to consume bandwidth.
979  Other / CPU/GPU Bitcoin mining hardware / Re: What does the new Southern Isles architecture mean for mining? on: June 19, 2011, 02:09:55 PM
It's a die shrink from 40nm to 28nm using the same VLIW4 stream processors.

There is room for more transistors and the chip becomes smaller (less power consumption, runs cooler). Going solely by die size, a modest estimate would be at least 30% faster than current 6xxx series cards.

They could have been forced to make architecture changes as well due to competition; Nvidia is known to bring out the Kepler arch. later this year or early 2012. They boast 4x performance increase over Fermi which is massive (could make Vvidia cards viable for OpenCL mining).

Then again, Nvidia grossly overrepresented Fermi's capabilities as well. They said it was "revolutionary". GTX 480 was only 20-40% faster than their previous single-core flagship GTX 285.
980  Bitcoin / Bitcoin Discussion / Re: Ideas for the Perfect Bitcoin Exchange on: June 19, 2011, 01:27:26 PM
for me, a zero fee mtgox would be perfect Smiley

You can't run a professional exchange with zero fees.
Since actual human beings will be operating it full time (many transactions not automated), they will also need to cover their living expenses + risks incurred.

Not to mention office rent, lawyer fees if need to consult them arises, electricity, hardware, local taxes etc.

0.65% is actually very reasonable compared to other services like PayPal that charge multiple %.
