Thanks!

And glad to hear it works.  I went through the same thing, spent a week pulling my hair out, could not figure out what was going on

Glad to hear you figured out what the issue was.

Like I said, RAM might be OK it just didn't like your motherboard's timings, etc. Try 1 stick instead of 2 and see what happens

Thanks!

I have built 1000 of computers, all brand new parts, have had many problems like this!

Newegg.com once told me, about 5% of the parts they ship are defective, hard drives more like 7%.

It may be your ram is 100% fine, but motherboards come with a list called "QVL" (qualified vendor list), if your ram's model # is not listed on the QVL for your motherboard model's #, then it is offically not supported. Nobody really pays attention to this, but I have seen it cause problems! My own PC had this issue a few years back. RAM was fine, motherboard was fine, but they didn't like eachother.

anyway,
bitcoin-qt puts your ram+cpu at 100% when processesing the blockchain, it's the exact kind of program that would mess up if there was even the smallest issue.

another program to try is Prime95

http://www.mersenne.org/freesoft/

it has tortue test that should never fail, let it run overnight, if you get a single error then its hardware issue

(skip the login stuff... just use it for the benchmark/tortue test)


10,000's of people run bitcoin-qt with no errors... I doubt its a software bug.

here's what I'm talking about

http://windows.microsoft.com/en-us/windows7/diagnosing-memory-problems-on-your-computer


if it passes, try the extended test (which is super slow and takes a long long time)

I have worked with pc's for 20+ years - I bet you have an issue with your PC - either the RAM is bad, or there is a mismatch between the motherboard and RAM. I've seen it many times.

You only see problems when using programs that stress the RAM/cpu, such as bitcoin-qt does

Do a memory diagnostic - Windows 7 and 8 have a built in one. Let it run overnight. If it passes, pick the advanced test and let that run overnight again.

Do not use your wallet on that PC until you are 100% sure there are no issues. Else you could courrupt it.


If it is not the ram, it could be the hard drive or sata cable connecting the drive. But that's less likely then a RAM issue

Good luck

someone's getting some crazy high numbers, a good gfx card can't go about 400khs

I was surprised to learn Bitcoin is not really for micro payments. The fee right now is .0005 which is 6 cents.
That would be ~ 50 cents if the price got to $1000

Are there any ideas how to 1) add another layer to bitcoin , to allow for micropayments (perhaps a 2nd network)
or 2) an altoghter different coin, that is only used for penny-sized transactions?

I have been using Trixx and I never realized cgminer can OC on its own , thanks

Actually I would delete everything but wallet.dat , reload, then put that bootstrap file in .... don't try to reuse old files from old computer (exxcept obvisouly wallet.dat)

There is a torrent you can download with most of the blockchain by Jeff Gzarik (sp), called bootstrap.dat , try loading that

Here it is:
