Thread: What means "1024/4096 MB allocatable"
Post: RE: What means "1024/4096 MB allocatable"
| OpenCL has a bit a strange policy on memory allocation:

Max size of memory object allocation in bytes. The minimum value is max (1/4th of CL_DEVICE_GLOBAL_MEM_SIZE, 128*1024*1024)

Thread: Hashcat 3.0 inc_vendor.cl missing
Post: RE: Hashcat 3.0 inc_vendor.cl missing
| Look like AMDs OpenCL runtime (on windows only) silently ignores the -I parameter. It's configured correctly, as you can see in the debug output:

Thread: hashcat v3.00 + ntlm performance
Post: RE: hashcat v3.00 + ntlm performance
| It was always that fast (in oclHashcat), I just didn't backport the optimizations to hashcat-legacy. If you want to know more about the partial reversal used read this: https://hashcat.net/events/p13/... |

| It's a pure OpenCL runtime error. Not Hashcat fault, 100%. Sorry. All I can think of is to true a different OpenCL runtime. For example POCL, but that requires you to install Linux. |

| This is wrong, for sure, and for sure it's an OpenCL runtime error. We have no influence on this, you need to report to NVidia. Until they release an updated version you can use -D 1 to use your CPU. |
