Not enough allocatable device memory for this attack

[BowenD]

Hello guys,



How are you?



I just have this error when i used hashcat..

 hashcat --user hash.txt ~/rockyou.txt
hashcat (v6.2.5) starting in autodetect mode

Pure kernels can crack longer passwords, but drastically reduce performance.

How do I solve it?

well it seems you are on a vps or something similar?

1.5 GB RAM in total seems very odd in these days, i mean for sure, every consumer laptop nowadays has minimum 4 to 8 gb

cracking hashes needs power, storage and ram, real power (at least one dedicated gpu would be great)

you could try adding option -O to use optimized kernel, but im not sure if this helps

Hello Snoopy,

Yes i am using The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) linux in VMware..

Is it because hashcat did not detect my host computer's RAM?

kind regards

i think you created your vm with standard settings, given this your vm has probably 2 gb in ram only , if you are running this on your own machine, modify your vm settings and adding more ram to it

hello forum,



my windows 10 laptop is also showing the identical problem.. ...any solution for this... guide me . thanks for the help.

Your mask is way to big. You don't have enough memory to contain all the candidates. Try with --increment-max 9 or 8 although this is still a lot of candidates. Maybe you should not increment at all.

Next Thing, OpenCL 1.2 is way to old, use at least 2.1, install this opencl driver from intel
