One hell of a difference in sisoft anyway. Thanks to A64 tweaker I was able to get 1T command rates for my RAM . Difference was astounding.. 4500mb/s in bandwidth with 2T, and about 5400 mb/s with 1T. With a few other tweaks I did (just in my bios), I changed my DDR from 2.5-4-4-8 to 2.5-3-3-6 with the 1T. All stable, I can't believe it! With that I also overclocked my CPU from 2ghz to 2.4ghz (I had to lower the HT multiplier to 4x though to get it to boot, as well as change the ratio to 2/1.66 for 240/200). With all those settings, I jumped from about 10700 to 11400 on 3dmark03. Is that considered good? I'm still an inexperienced OC'er (I know all about it, just haven't experimented a lot, that's all). Things are a lot more responsive, loading times are noticeably faster. I can't say it's a huge difference in games though, in Oblivion maybe like 5-8fps difference on average.
