I have been using it since May and it worked perfectly. Windows 7 ultimate 64bit booted up in 12 seconds. It came with DXM03B0Q firmware. I wasn't able to update firmware up until today when i installed Windows 8 pro 64bit. After firmware update (via Samsung magician 4) i installed MB and GPU drivers and after that optimized it for performance. It takes almost 30 seconds for Win8 to boot.

SSD was never below 50gb of free space.
Before windows instal CPU and RAM were returned to stock clocks and AHCI mode enabled.

Is there anyway to fix this ? maybe go back to older firmware ?

rest of my spec:
FX 6300
Patriot viper 3 black mamba 2x4gb 1866mhz ram
MSI 970a-g46
MSI GTS 450
Hitachi 500gb HDD
Thermaltake 630w psu
ASUS DVD-RW
