i am trying to recover my litecoin wallet and i have all up to date drivers installed from my GPU
my friend does 1000 hashes a sec with 4 gig card i only 80/sec its weird whats going on?

Your GPU is old and slow

vram is about the most insignificant performance indicator for a graphics card.
no its a powerfull card 4 gig from GeForce GT 730, 1024/4096 MB allocatable, 2MCU

4 gig is not 1 gig or 2 gig

and my CPU cracking goes same speed so its not normal
The GT730 is a very low end card that's a few years old. It came in two versions, with 384 or 96 cores and different frequencies. For example, an older GTX980 has 2048 cores, a newer GTX1080Ti has 3584 and the brand new V100 even 5120 cores.

A GTX750Ti does ~700h/s in litecoin. Considering its 640 cores and clock speed, it seems like you have a GT730 with just 96 cores. That would be really poor.

And again, the size of your GPU RAM does not matter at all. You could have 60000MB and it would not run any faster. Big difference to games.

You can try to add -w 4 to your command line and see if it gets a bit better.

And if you have the exact name of your card I could tell you what kind it is and if that speed is okay or not.

am I supposed to laugh or cry now?
nice kitty undeath
i see in the info the Vram is at 3% not even been used for the password recovery
Kind of exactly what everyone has been trying to tell you. Core count, clock rate, instruction set are things that matter.
