How would one go about enabling AHCI mode on a Dell Optiplex 320? I have installed a SanDisk Ultra+ 256Gb SSD and cloned my Windows 8.1.1 install over, then re-aligned the partitions, but I'm still getting "pciide - BAD" in AS SSD benchmark, so I wish to use AHCI. I have looked in the BIOS but cannot find an option for changing the setting.

It doesn't look like it supports it. The ATI chipset in it (Radeon Xpress 200) was used by Intel for a very short period (just before AMD bought ATI) on some low-end boards, and it sucked/had limited features (based on personal experience with a few of them back in the day).
It CAN support AHCI and RAID, but probably wasn't implemented by Intel/Dell in your system. The lack of the options in the BIOS (and no mention of either in the manual, beyond the Glossary) supports this.
If not already, you may want to try latest BIOS for that motherboard -- but I'd say you're unfortunately out of luck -- the board most likely just doesn't support it.

Would it be possible to overrride dell/intel and enable anyway? – ja_ke – 2014-08-03T16:12:59.293
No, because it's not actually implemented in the hardware. You'll need a newer/better motherboard. – Ƭᴇcʜιᴇ007 – 2014-08-03T16:13:58.027
