I was wondering if I should use all my Ram slots. Currently I have 320 MB (2*128 PC133, 64 PC133) . Should I use only two slots on my MSI K7T Turbo instead cause I read somewhere that two was better than three? Is it affecting my overclocking too cause I can't seem to get my duron 900 to work using a 133FSB (ex: 8*133 or 7*133) even though it works fine at 11*100. Got any ideas?
