I have four modules of Corsair CMX512-3200XLPRO in my motherboard (DFI LANPARTY UT nF4 SLI-DR Expert). They run stably at a timing of 2-4-4-0 (default - i have not made any changes) however I want to run them at their potential 2-2-2-5 timing. Are there any recommended settings/bios mods I can use?

First thing, you will need to set the settings manually and we officially only gaurentee the tested settings with one Twinx set of modules. With 4 modules and this MB I would suggest Cas 2.5-3-3-7 at DDR333 at 2.8 Volts and then tweak from there for best performance.
