Ziber is that the name based on Uber or Viber? Or you have already cooperated? Can't get why the name sounds very close to these two. Undecided
You have no imagination

Purchased two 6990 cards and were delivered promptly overnight.

Was also very patient with me converting $$ to bitcoins which took forever (had to go from Bank Account > Dwolla > MtGox. process took about 10 days cuz of an overlap during weekend but it felt like 1 year).

It depends on the brand and the timeline but I would be somewhat interested.

Discount rate if we buy 5-10?

I'm confused.

You said you have new ones for 999 and used ones for 949 but on the webpage it says:

"Description:
Slightly used HD6990 Video Card. Not Only Great For HD Gaming And Video, but it Improves speed Of Bitcoin Mining!"


So please clarify, are they used or new?

My definition of new is "not put on the motherboard yet"


Also, please clarify how old they are? How many months were they in use?


Thanks!

Outta curiosity, what's the diff between the two 5830s?

Obviously one of them is price but is there a diff in performance?

Card 1, $129.99

6  Bitcoin / Mining / Re: To people who are technically versed: Will the HD 7xxx series be good at mining? on: July 05, 2011, 06:06:19 AM
Considering that the 7xxx was due out Q3 2011, I'm kinda surprised the official specs haven't been released yet.

Specs are usually released at 6 months ahead of launch schedule.

Does this mean that they will be delayed? We are already in Q2.


I heard a rumor from a wholesale supplier about the shortage of 6990 cards. He said something to the effect of:
"In general, the manufacturers don't produce too many high end video cards like the 6990 because they aren't for the mass market but only for high-end gamers. Combine this with the earthquake in Fukushima, and there is a shortage of high-end transistors that can ONLY be found from the Japanese companies"

If so, I'm only guessing that:
1) natural shortage of high-end cards to begin with
2) shortage of transistors due to Fukushima
3) bit mining demand surge


If all factors of the above are true, it makes sense why the 6990 card is a bitch to find.

If we combine this factor with the possibility that the 7xxx card may not even include SHA-2 (still unconfirmed) and thus, not ideal for mining, we could be facing a HUGE short-squeeze in 6990 cards for at least another year.

Any comments to the above?

How much power do you estimate it is sucking?

For the lay person, can you explain "zero-variance" again in real-dollar terms?

For example, we all know the difficulty now is 1,379,223, which currently yields and approx of .73 BTC / day, 22.17 BTC a month

and is set to go up to 1,571,848 which will yield less.

The question then is, as difficulty goes up, safe to assume that the yield in BTC will decrease right?

Hi there.

Were u the one who made a posting in silk road a couple of weeks ago?

Someone made a post at the time but I forgot to save it. If so, can you pls msg me and whether or not it's too late to join?
10  Bitcoin / Mining / Re: To people who are technically versed: Will the HD 7xxx series be good at mining? on: July 03, 2011, 08:01:29 AM
So back to the original question:

1) SHA-2 capability has been removed from the upcoming 7xxx series, thus, won't help miners

2) The 7xxx specs hasn't been specified yet so we do NOT know if it will outperform the 6990 yet?

Ending in 5 hours! get it quick for atleast half the retail price!

Sorry if this is a dumb question but...
I'm confused if the H20-320 is for the GPU or the CPU?

You said u used it for your GPU but the product seems to be made for CPU.

Please clarify.
Thanks.

Agreed, Many benefits to be had by running 6990 vs 5830's but it's not worth paying the extra, Retail is pricey enough
and those "problems" your talking about dont exsist anymore, The worst you'll get is a crappy oc card that only give 760Mh/s that runs hot (95°)
where as shappires sometimes cant even push 25mhz past stock on core

In your opinion then, which brand of 6990 allows for best OC?
XFX?

From what I've read and heard, Sapphire is one of the better 6990 cards out there... no?
 Huh

While I agree in the content, the point *I think* bitcoindude was making is this:
any time they see command lines, people simply freak out and their brains immediately fallback into MEGO mode (My eyes glaze over).  Huh Shocked

I am a PhD scientist and have spent several years translating applied science into protocols for people with minimal training to follow (in pharmaceutical industry). Trust me, it is not easy! One must very specifically define each variable and downstream relationships.

We are at the point where MASSIVE amounts of money WANT to roll in but are afraid of security related issues.

From my interactions, I have concluded that lifetime investors (40-70yrs) old with successful history in the global markets are the key demographic. Guess what, most of them barely know how to send email, but very much realize the growth potential of this thing.

We need a WELL WRITTEN STEP BY STEP MANUAL endorsed by votes!!! and we need it NOW!!!

While I agree with you that the 40-70 year old demographics are sitting on a huge chunk of $$ AND the fact that they are mostly computer illiterate and have NEVER touched a command line interface before, I doubt you'll see this "dummy-proof manual" written and--more important--widely adopted by this group of folks any time soon. It's simply asking too much for the average folks.

My feeling is that this so-called "theft" (which we have to take at face value since there really is no proof other than one person's claim) may actually be a good thing for bitcoin. After all, necessity is the mother of all invention. This is what I predict will happen:

1) A spawn of third-party brokers/bankers willing to hold your bitcoin deposits for safety. Of course this means sacrificing some level of anonymity but that's the price you pay for security. In addition, there will be a service charge added.

Think of it like this...what if a trusted brick&mortar bank or entity or institution that complied within legal banking laws offered you the ability to deposit your bitcoins? And the only way to withdraw them would be the standard banking authentications of legal ID and PIN number.

In some ways, bitcoins are very similar to an entity like E*Trade where I sign over my actual stock certificate and deposit the shares into my account for trading & safekeeping.

This is a win-win for some, but not for those who want to stay anonymous. Nevertheless, there will be a market for it that fulfills that demographic you mentioned.

2) Third party security consultants who specialize in illustrating that hypothethical "MANUAL" you wish for and possibly taking even further steps & safeguards as well.

3) Other jobs & services & products will be created to get around the high technological barrier of safeguarding your bitcoins....e.g., a book published "Safeguarding bitcons for Dummies" (if it hasn't already been written) and dummyproof it by possibly using non-command line linux or phone apps.

As bitcoins grow in popularity and demand, it will only create more ways to fulfill the needs of the 90% technophobes out there. And in the end, this will be a good thing.

Just my .00000002 BTC worth!

I'm not running anything near $10k. I just don't want to get bitten for a foolish mistake.

Thank you very much for your help and clarifications.


This then begs the question, what if we DO run over $10k?

I have an IT background by trade so I'm leaning towards converting a few of my spare parts into some powerful mining rigs.
Not that I will make over 10K but for the sake of arguing hypotheticals, then what?

I'm sure many folks mining who have an entire array of rigs are probably dealing with the same question now.

I come from the world of Cisco voice where we virtualize images all the time using VMware.

As most of you know, VMware allows u to run an entire OS on any PC.
So the question is, couldn't the wallet.dat be securely installed in any operating system of your choice through VMware(whether it be windows or linux), then secured with two passwords:
1) username / password on the VMware host itself (see image)
2) username / password on the actual login when the Guest Operating system is turned on (think username/password when u login to any XP box).

Of course you will still have to create duplicates as safeguards and it's not 100% foolproof but it allows u the benefit of:
- have a working copy of it existing in your computer and backed up in an external devide (USB for example)
- have it turned "OFF" when not in use yet still safely reside in your computer.

It's not as foolproof as aiwk171's post but just wanted to get feedback on the VMware option.
