Samsung 840 pro 128gb slowed down after firmware update

post #1 of 6
Thread Starter 
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

The Firmware ist not the Problem. It works just fine. I think the rason is the Magician "Optimization". Never do this. Magician does not make any difference in optimization, whatever hardware you use. Reinstall Windows, install drivers, benchmark your SSD. Install Magician just to check for FW updates. Remove it from autostart and leave it be =)

Is the CrystalDiskMark test from Windows 7, and AS SSD test from Windows 8? I assume it is. The new firmware did not cause your problem, many forum members use that firmware version (me too) and it does not ruin the SSD's write performance like your SSD has now.

While you cannot exactly compare the Crystal and AS SSD results, since they are different tests, the AS SSD test looks like something happened when you installed Windows 8, or before that.

What did you do to prepare the SSD for Windows 8? Format it (quick or full) in Windows, or used another program?

Are you sure your BIOS and SATA driver are configured correctly after the Windows 8 installation?

The 30 second Windows boot time is not your main problem, it really is the terrible write performance.

All tests are for windows 8. I dont have any Win7 tests to compare them, but i do remember that in samsung test both random write and read were above 70000 and sequential write +380ms/s. Also in windows 8 experience index score remained 7.9 (same as windows 7)
