Low Read Speeds on Crucial MX100 SSD

[DemonDragon]

I've recently got a Crucial MX100 SSD and the read speeds on the Asmedia 106X SATA Controller are horrendously low, around the 4MB/s - 7MB/s. I'm wondering if this is an issue with the controller or the SSD itself. Running the ATTO benchmark causes the computer to restart itself after a random amount of time, without a blue screen or any kind of error.

My motherboard is an Asus M4A79XTD EVO which only has SATA 2 ports on the motherboard, hense the reason I am using an external controller to maximize the speed a bit more. I have tried the SATA 2 ports as well and it was causing freezing every so often. Taking into account this is a clean install of windows so I haven't a clue what the problem is. I have disabled disk defrag and indexing on the drive, as well as legacy USB support in the BIOS as that was also causing problems.

I would like to know how to stop the computer restarting itself while running the ATTO benchmark and make the read speeds higher if that is possible.

Move the ssd to the sata2 ports on the motherbd and see if it jumps to ~240mb/s max
If it does then you either have a bad 106x controller or a conflict with it and whats onboard.
