Hi folks During the course of trying to troubleshoot recent BSoDs I bought 2gb of RAM to replace my existing (2gb) RAM. As it happens the problems were with Steganos Safe but I haven't installed all 4gb of RAM yet. I replaced my existing pair of 1gb sticks with the two new ones but wonder if it's OK to have all 4gb in my PC. I kind of assume that the more the merrier but perhaps this isn't the case in all circumstances (?) Here's a quick run down of my system: Silverstone Temjin TJ05 case ABIT AN8 32X motherboard AMD FX60 Dual Core CPU 2 x 250gb Samsung Spinpoint SP2504C drives (in striped array) 2 x 256mb nVidia 7800GTX SLI graphics cards Soundblaster Audigy 4 soundcard Corsair XMS PC3500LLPro (2 x 1gb matched modules) Windows XP Professional (SP2) Any thoughts? Could excessive heat be an issue?
