all the corsair vengence kits on newegg are 1.5v modules.
Look up your specific modules to get their timings, something like 9-9-9-24.
Next go into the bios's memory section and see what its set to. If it doesn't match what you looked up, voltage and timings, then set it manually or reset the cmos and hope it does a better job detecting it when you boot up again.
