HD 4600 allocatable memory hashcat 6.2.4

[EnviableOne]

OK so I have been playing with this for a few weeks, and had to roll back to 6.2.2 for some reason when running version 6.2.4 I can't even benchmark NTLM

my free GPU memory drops from 1565MB to 768 MB



407 MB allocatable becomes 203 MB allocatable


and hashcat doesn't have enough allocatable memory to run an NTLM Benchmark, and a -b just stalls on the MD5

Code:

D:\audit\hashcat-6.2.2>hashcat -b -m1000
hashcat (v6.2.2) starting in benchmark mode...

Benchmarking uses hand-optimized kernel code by default.
You can use it in your cracking session by setting the -O option.
Note: Using optimized kernel code limits the maximum supported password length.
To disable the optimized kernel code in benchmark mode, use the -w option.

Any suggestions would be useful, I have updated the drivers the best I can,



both drivers are native intel, I have the latest OpenCL for the CPU, but that just seems to complicate matters




here is the backend info from both versions:
