1  Bitcoin / Mining software (miners) / *Catalyst 12.1 Preview* Decreased performance, anyone else confirm? on: December 15, 2011, 05:07:41 PM
Previously I had a 5830 running at 272 Mhs with Phoenix 1.7 Phatk2 128worksize on Cat 11.11

Now getting 250 Mhs with the same settings.


Anyone esle try the preview? Going to try installing the old Opencl Package from 11.11 ontop of 12.1

(I was able to bring it back up to 265 Mhs with the original Phatk kernel, but still not as nice as 272....)

A few quick pointers for newbies running Windows.

Now to really do farming with Bitcoin you should setup custom linux distros to boot from flash drives preferably, of which there are many guides around the forums, but it is understandable to want a dual purpose machine now that the price has settled and for that most of you will want a windows box.

Advice #1:
Get some Malware protection. Spybot won't cut it.

Since we are in this for the money (most of us) I suggest Microsoft Security Essentials, it is free and works well in conjunction with Malwarebytes.

You can either use Malwarebytes on a scheduled scan, or preferably buy a license for the realtime protection. Newegg often bundles OEM disks with motherboards and other components, so knock it out there if you can since the costs will be much cheaper.

Use Blocklists.

Grab a copy of Peerblock 1.1 (or whatever newer version at the time of reading)

Peerblock is an excellent tool for local IP address banning, you can import custom blocklists from

I suggest:
primary threats
and the default spyware filters.

This can also be useful for gamers and P2P hounds.

Alternatively or in conjunction you can use the HOSTS file native to windows for blocking known bad IP's.
This can be done manually and you can find out how from a simple google search.

A simple GUI for accomplishing this the easy way can be found here:

Block Javascript when browsing.

The forum hack awhile ago should be proof of this, people will and are using Javascript Miners to generate bitcoins off of your browsing.

To help protect yourself I suggest installing NoScript if you use Firefox, or using Chrome's built in javascript exceptions.

In Chrome goto Options -> Under The Hood -> Content settings

Turn off plugins and javascript for sites you suspect may be trying to steal your logins or mine coins. At the very least block them for this forum.

Use a virtual machine for your wallet.

If you are adverse to linux and have a copy of Windows 7 Professional, you can install a free version of Windows XP as a Virtual machine called "XP Mode'

Setup this machine with the wallet application and then never use it to do anything other than access your wallet.
3  Bitcoin / Mining software (miners) / Windows users do not need to download the 2.4 SDK separately, OpenCL is included on: June 16, 2011, 03:35:33 PM
The only thing Windows miners need are the standard OpenCL drivers which are INCLUDED by default in the regular Graphics drivers in Catalyst 11.5 and 11.6. Earlier versions required you to download a 'stream edition' that no longer applies.

I haven't installed the SDK even once and I've built 3 dedicated miners all running high hash-rates.

The only thing needed to run OpenCL code is the driver, the rest of the SDK is essentially bloat for normal users.

If you happen to have an issue, then you can install the SDK to see if it fixes the issue but it is silly to waste the space upfront, especially if you are using a PXE image or a flash install.

Word out to the fantastic coders out here.

It would be nice to subscribe to updates so we can stay on the latest version of our favorite mining clients.

That is all - keep hackin away.
