Catalyst 13.4 GUI-Miner FIX BFG-Miner / CGMiner

[knappknackslive]

Hallo Bitcoin gemeinde,
einige von euch kennen es vielleicht. wenn man mit dem GUIMiner und Catalyst 13.4 versucht zu nutzen und man in der Konsole nur den Fehler : "Verification, Check Hardware!" oder "invalid nonce - HW error".
Wenn dieser Fehler vorliegt muss man nur etwas in dem Ordner des Miners bearbeiten.


1. Man sucht in dem Miner Ordner nach phatk.cl.

2. Man öffnet diese mit einem Editor (z.B. Notepad++)

3. Man sucht nach dieser Textstelle:

#ifdef BITALIGN
#pragma OPENCL EXTENSION cl_amd_media_ops : enable
#define rot(x, y) amd_bitalign(x, x, (uint)(32 - y))

// This part is not from the stock poclbm kernel. It's part of an optimization
// added in the Phoenix Miner.

// Some AMD devices have Vals[0] BFI_INT opcode, which behaves exactly like the
// SHA-256 Ch function, but provides it in exactly one instruction. If
// detected, use it for Ch. Otherwise, construct Ch out of simpler logical
// primitives.
#ifdef BFI_INT
// Well, slight problem... It turns out BFI_INT isn't actually exposed to
// OpenCL (or CAL IL for that matter) in any way. However, there is
// a similar instruction, BYTE_ALIGN_INT, which is exposed to OpenCL via
// amd_bytealign, takes the same inputs, and provides the same output.
// We can use that as a placeholder for BFI_INT and have the application
// patch it after compilation.

// This is the BFI_INT function
#define Ch(x, y, z) amd_bytealign(x,y,z)
// Ma can also be implemented in terms of BFI_INT...
#define Ma(z, x, y) amd_bytealign(z^x,y,x)
#else // BFI_INT
// Later SDKs optimise this to BFI INT without patching and GCN
// actually fails if manually patched with BFI_INT

#define Ch(x, y, z) bitselect((u)z, (u)y, (u)x)
#define Ma(x, y, z) bitselect((u)x, (u)y, (u)z ^ (u)x)
#define rotr(x, y) amd_bitalign((u)x, (u)x, (u)y)
#endif
#else // BITALIGN
#define Ch(x, y, z) (z ^ (x & (y ^ z)))
#define Ma(x, y, z) ((x & z) | (y & (x | z)))
#define rot(x, y) rotate((u)x, (u)y)
#define rotr(x, y) rotate((u)x, (u)(32-y))
#endif



Und ersetzt diese durch:

#ifdef BITALIGN
#pragma OPENCL EXTENSION cl_amd_media_ops : enable
#define rot(x, y) amd_bitalign(x, x, (uint)(32 - y))

// This part is not from the stock poclbm kernel. It's part of an optimization
// added in the Phoenix Miner.

// Some AMD devices have Vals[0] BFI_INT opcode, which behaves exactly like the
// SHA-256 Ch function, but provides it in exactly one instruction. If
// detected, use it for Ch. Otherwise, construct Ch out of simpler logical
// primitives.

//We have an SDK which automatically optimizes to BFI INT, so lets do this

#define Ch(x, y, z) bitselect(z, y, x)
#define Ma(x, y, z) bitselect((u)x, (u)y, (u)z ^ (u)x)
#define rotr(x, y) amd_bitalign((u)x, (u)x, (u)y)

#else // BITALIGN
#define Ch(x, y, z) (z ^ (x & (y ^ z)))
#define Ma(x, y, z) ((x & z) | (y & (x | z)))
#define rot(x, y) rotate((u)x, (u)y)
#define rotr(x, y) rotate((u)x, (u)(32-y))
#endif

4. Wenn man noch die Datei phatk.bin in dem Ordner hat, sollte man diese löschen.

5. Den Miner starten und Minen


Viel Spaß
