    Overclocking ROI
    It might seem strange thinking about ROI (Return on Investment) when it comes to overclocking but when you are being judged on how far you are putting your builds it pays to start low and aim high.  However, there is some trickery in the world of computer hardware between base clocks to boost clocks and how much of your processor is actually getting boosted.  The Core i9 9900K is an 8-core processor that has an advertised base clock of 3.6Ghz and a boost clock of 4.8Ghz.  On a proper motherboard this processor will never run at 3.6Ghz as the frequency will jump between 800Mhz up to 4.8Ghz and might even hit 5Ghz if the load is single threaded.

    What people don’t realize is that only two cores are boosting up to 5Ghz and if the load is high enough the CPU will top out at 4.8Ghz which really makes the processor a 4.8Ghz part instead of the 3.6Ghz that it is being sold under.

    Now for the fun part.  When you overclock this CPU the majority of them will hit 5.1Ghz which is only 100Mhz higher than the opportunistic high clock frequency making the ROI extremely low.  Contrast that with a Core i7 8700K that will get you 600Mhz+ and you have to wonder why you bothered to spend the extra money.

    Extremely Fast Memory from HyperX
    Dennis recently posted a news article linking to a post over at PCGamer.  The article was talking about the new 16GB memory kit from HyperX that was selling for $600 USD and clocked in at 4600Mhz.  As hardware enthusiasts  we try not to think about the cost but at over 6x the cost of a 2400Mhz memory kit you have to wonder why is it so expensive? And what did the company have to do to build it.

    In this segment Dennis and Darren explore the world of high-performance memory from HyperX, Corsair, and GSKill.  The results might surprise you.
