Slow C300 128GB SSD

I bought a Crucial C300 128GB SSD and I'm getting very slow speeds which I can't improve. I have an Asus P7P55D-E which has a SATA 6.0Gb/s connector and I'm using the correct SATA cable,I've also set the Marvell SATA controller to ACHI mode and disabled USB 3 as well. I changed the I/O level up settings as well yet I'm still only getting 274MB/sec read speed which is a long way short of 355MB/sec. Does anyone have any tips?

try downloading the intel drivers instead of the marvell ones.i read that the marvell drivers restrict the speed

Is there anything else hidden away in the Bios? My Asus AMD bios required me to select the 6.0GB/Sata 3 mode manually, for compatibility reasons, apparently.

That took me from Sata 2 speeds up to the land of the big boys! The speeds you show are the ones I had before I made the change.
