Wow. I am very glad to see this helped. someone actually sent me a bit of scratch as well, which prompted me to check this thread.
Certainly reinforces my desire to post any fixes or genuinely helpful suggestions. Glad this worked out for some people.
 I guess the drivers mentioned in this thread are woefully out of date, but the concept is probably still sound.

Well then buddy you're doing something seriously wrong.

Have a look at some of the GPU hashing speeds for Bitcoin. You can see they are marked as "Mhash/s" then go down to 7970 and you will see they can go up to 825MH/s with proper cooling.

ok, guess your right.

omg someone on the intarwebs admitted the other person was right. technically they didn't say that they were wrong, but it's close.
In case anyone missed what's going on here- SHA-256 can be hashed at a much higher hash rate with GPU's in comparison to the Scrypt algorithm.
So while a 7970 can hit 700Mhashes crunching the SHA-256 code, the same 7970 will only hash around 700Khashes when crunching the Scrypt stuff.

The point is kinda moot tho, as 700MHashes is a drop in the bucket...or more like a drop in the ocean, for bitcoin. Although 700Khashes is still somewhat useful for mining lower difficulty scrypt coins (doge maybe?)
If you get 16 of those 700Khash cards running you can make a nice $1500 profit on a month of mining LTC, depending on your power costs...

Just really interesting to see the "guess your right"
I don't care what they say about you Bobsurplus. you're ok by me.

Did anyone ever get clarification on whether being a miner in the USA requires registration?
The fincen guidance from march 18th says:

' A person that creates units of this convertible virtual currency and uses it to purchase real or virtual goods and services is a user of the convertible virtual currency and not subject to regulation as a money transmitter. By contrast, a person that creates units of convertible virtual currency and sells those units to another person for real currency or its equivalent is engaged in transmission to another location and is a money transmitter. In addition, a person is an exchanger and a money transmitter if the person accepts such de-centralized convertible virtual currency from one person and transmits it to another person as part of the acceptance and transfer of currency, funds, or other value that substitutes for currency.'

I'm an LTC miner, and i convert LTC to BTC and I'm thinking of selling that BTC for USD thru campbx.
If I do that, I'm thinking I'm a user of the currency, and the exchange (campbx) is the money transmitter.
I'm not selling them to another person, I'm using an exchange to convert BTC to USD.

What do you guys think?
4  Other / Beginners & Help / Windows 8 fresh install catalyst 13.4 drivers -cgminer gives error in amdocl.dll on: May 05, 2013, 06:36:13 AM
I did a fresh install of windows 8, followed by the catalyst 13.4 drivers.
cgminer 3.0.1.

running cgminer -n would show the Juniper device (5770), but when attempting to run cgminer to actually start mining, it would crash and give an exception in faulting module amdocl.dll

If anyone else is having this issue-
the fix was to use 4 different OpenCL dll files from a known good working computer:
File version 10.0.1084.4
Product Name: OpenCL 1.1 AMD-APP (1084.4)

I replaced amdocl.dll file size 28,732,928 bytes and OpenCL.dll (50,176 bytes) in the syswow64 folder.
I replaced amdocl64.dll file size 34,518,016 bytes and OpenCL.dll (54,784 bytes) in the system32 folder.

I've uploaded the dll files to 4shared
http://www.4shared.com/zip/M5RSKSNt/opencl.html

If this helped you, feel free to throw me LTC 0.01 or whatever just so i know this was helpful LQNaaAqWc4SB7uwr53o1J4hZBt2wUxZAsK
