Either use the 1.8v modules, or use the 2.1v modules. Check if you can change DRAM voltages in the BIOS. | Report abuse bigjamesbo March 14, 2010 3:30:43 AM Well I got the ram, my son and I installed the two 2gb sticks and they work perfectly. Instead of 4-4-4-12 they run at 5-5-5-15. 1.8 volts versus 2.1 didn't end up be a problem. Thanks to all.
