When I run diagnostics I get unstable numbers as shown in picture setting 1 and 2 (and these are only two out of like 5 different numbered pictures). After overclocking my memory timings are as shown in memory picture. I don;t know why but my PC slows down terribly when I play games for like 4, 5 seconds. In 3dMark06 I get only as much as 2000 something scores!! And if that wasn't all I can't even put in all 4GB of RAM I bought (using only 2GB as of now had problems with 1 long beep and 2 short ones - isn't that a video failure??) Anyway, any help would be appreciated!! If you need more info just ask I will try to answer every questions to my best knowledge! And also included my BIOS settings after overclocking. Thanks!!
Vinny, it looks like from the first screenshot that Cool'n'Quiet might be enabled. Make sure that feature is disable via BIOS before you start overclocking. I would also make sure any features related to "Spread Spectrum" are also disabled.
One thing to remember with Manchesters is that they require quite a bit of voltage for any decent OC in the range of 2.7 - 2.8Ghz. Just keep that in mind when you start getting up there. Make sure to manually input your voltage when you start raising the HTT (reference clock).
Your memory timings look really tight. You may want to loosen them especially if you plan on running 4GB of memory (4 x 1 DIMMs). Try timings such as 3-3-3-8 2T. Also keep an eye on your memory frequency and make sure it doesn't exceed to far past stock. Another thing to note is that multiple sticks of memory can and will stress your IMC (integrated memory controller). This may prohibit your overclock. The downside to that is 64-bit Vista runs perfect with 4GB of memory so running anything less may be a bummer.
I'm sure others will chime in to assist you. Welcome to OCN
