If i recall correctly there was a trick to fix your issue, it was not well known. I cannot recall what exactly it was but maybe someone can pitch in about it. It was somewhere on the NBR forums. but i believe you had to remove all ram sticks, power on the system, let it keep beeping and then put 1 ram stick in before power cycle. maybe it was this: Turn the system off and disconnect the AC adapter Disconnect CMOS battery and system battery** Do a power drain (press and hold power button 30 seconds) Remove all memory modules Reconnect AC adapter and power system on Let laptop beep until it turns itself off VERY QUICKLY, WHILE IT IS OFF, BUT BEFORE IT ATTEMPTS TO BOOT AND LIGHTS COME ON AGAIN, INSERT 1 MEMORY MODULE System will start to beep 5 times Power system off Reconnect CMOS battery and system battery Replace any panels removed for access to memory modules Done

I'd really appreciate it if you were able to put a guide not only for the alienware m18, but all systems that have this issue. I personally have the m17 r2, and I cannot undervolt it anymore
