i am getting this error

HAXM is not working and emulator runs in emulation mode
emulator: The memory needed by this AVD exceeds the max specified in your HAXM configuration.
emulator: AVD RAM size = 1024 MB
emulator: HAXM max RAM size = 512 MB

i have installed intel *86 Emulator Accelerator (HAXM installer) from standalone SDK manager option and have also tried making new virtual devices.
Any help will be deeply appreciated
