    Is it possible to OC FSB to match RAM speed in R400?

    I'm new to OC'ing but I have recently spent seemingly countless hours reading up on the topic. I'm still trying to grasp RAM timings and what's possible in general with FSB OC.

    I bought an R400 with P8600 2.4Ghz C2D and 4GB DDR3 1066 installed. I downloaded CPU-Z and I'm not sure if i'm completely off base but I think my memory is running at half speed because of the FSB :DRAM timing of 1:2. If this is a correct assumption, if is safe (or plausible)to OC FSB while lowering the multiplier to achieve a 1:1 ratio with memory? ie: fsb 532 and multiplier 4.5. I don't really care to increase core speed rather than fsb. My gut says there has to be some kind of mobo compatibility to achieve this, otherwise it would be configured this way from the manufacturers.

    Whether this is crazy or plausible please respond with a detailed explanation as to aid my understanding on the subject. Also, if you have any other safe tips/tweaks for my hardware I'm all ears. Thanks in advance

    With most laptops, overclocking is not readily something I would recommend doing... they are built to run within certain thermal tolerances, and a tweak here or their may provide a small performance increase, but it's not generally worth it.

    There are specific overclocking forums around that you would be best to discuss these things in.

    Adding some more memory to your laptop will generally give the most cost effective performance upgrade at the lowest risk.

    Outside that, buying a new laptop is the best bet.

    These days, yes, if you can live with a small drive, an SSD is a great upgrade.
