I recently changed my timigs on my memory sticks (2x 1GB Geil 800Mhz Dual Channel Kit). I've set them to 4 4 4 12 as the manufacturer guarantees them to work. Then i went on to increase my memory voltage from default 1.8V to 2.0-2.1V, but my mobo (Asus P5B-SE ) doesen't seem to allow me to go beyond 1.9V. So, my question is: Is there a chance that my mobo is limiting memory voltage and if it does ,is there a way to change it (i upgraded BIOS with no succes) ,maybe a reprogammed version of BIOS ? The other thing i'd like to know is if my curent 1.9v voltage is enough for cas 4 timings since the manufacturer says that default should be 2.1? If there is any way to reprogram BIOS or some other solution please do let me know. Thanks in advance.
