SSD performing badly at 1.0Gb/s speeds

I have an Asus A8N32-SLI Deluxe motherboard with the nForce4 SLI chipset. I purchased an OCZ Agility 3 60GB SSD and can't seem to get anything faster than 120+MB/s speed out of the thing. I have no AHCI option in bios, only IDE and RAID. I am currently running Linux Mint 12 but have also tested with Windows XP and see the same results. I also have updated the firmware and even sent the drive back to OCZ which they tested in an intel board and got the 500+ MB/s throughput, so I know it's NOT the drive.

Is there ANYTHING I can tweak in BIOS to get better performance than this??

Try this:

Set the SATA ports to RAID, but don't set up an array. (On Intel chipsets, RAID defualt is ACHI when drives aren't in an array.)

Otherwise, it's your motherboard. Try a PCI-e card to plug the SSD into, like the Velocity Solo advertised on THG. But I have no experience with it.

Normally that would work, but since AHCI is not supported on that particular chipset it will default to IDE mode. Won't hurt to give it a try through.

I tried to set it to RAID and no matter what setting I used it either wouldn't accept it saying I needed another drive or would but then wouldn't boot. I'm not willing to set it to RAID then reinstall the OS, nor do I really want to put in a SATA card unless it's around $20 and I know it will work.

I guess I just wait till I upgrade for the performance boost. The latency improvement is REALLY nice though, just wish I got better then like 130MB/s sustained read.

Thanks everyone for your help
