Hello everybody. I am currently experiencing some of the problems described in this thread, and considering that this thread is not closed yet, i might as well just ask away.. My laptop is the same, R60Plus, with the 2x 1Gb Samsung PC5300s as standard. It's been working fine since 2008 september, and at last i thought i would upgrade to 4Gb, seing as maximum 4Gb appears on every website i've seen. So, saturday, the delivery man comes, and brings me 2x 2Gb Corsair PC5300 (667 Mhz, 200Pin).. I install them both, i also install Win 7 from scratch, just to have everything clean.. Then, the fun began: freezes, occasional reboots and then progressively worse, first not going past the Win 7 Boot page and then in the end not showing even the boot up BIOS page. I also tried the 2 new sticks separately, only 2 Gb at a time, both tried in both RAM ports, they both behave like normal.. Then i say, perhaps one of the ports is in some sort of malfunction, so i try the original 2x1gb samsung rams, and everything is ok again.. Just as good measure, i tried with 1x 1Gb Samsung PC5300 and with 1x2Gb Corsair PC5300 and i still get the same result: freezes, crashes and so on.. What could i do?
