Alienware Aurora alx overclocking problems

Hey guys im just a bit fed up about overclocking my Aurora alx mainly with the cpu and the ram. I have a stable overclock with the I7 960 at 3.6ghz (150x24) this forces my ram Kingston Hyper X tri channel 6gb to 1500mhz (150x10) I want the ram faster at 1800mhz (150x12) I have read reviews that I can overclock this type of ram but when I do it it comes up with blue screen same with the cpu if I move it even a 1mhz (151x24) which is really dissapointment because I have flights simulater which is a very cpu and gpu intensive game. Hope you guys read this and tell me some answers to my problem!

    set base clock to 180, multiplier to 20, vcore to 1.24

    sorry, you probably have hyperthreading enabled by default, vcore might be more like 1.26

    Ok but the vcore is set to auto in the bios and I dont want to disable any of the intel technology for example turbo boost.

    did you do the adjustments?  should be 3.6ghz with 1440mhz ram instead of what you had prior.  If this works out, you could then try 190x19 for 3.6ghz with 1520mhz ram  (this might run too hot with the higher base clock)

    Turbo boost temporarily raises the multiplier for one core.  ie, when stressed, your cpu's multiplier will raise for one core.  Pretty much a dumb feature unless your cpu has a low clock.  Hyperthreading is another dumb feature that marginally raises performance for heavily threaded applications.  it also generates a huge amount of heat.  Hyperthreading essentially is a weaker cpu core to distrubute tasks to make the operating system believe you have twice the cpu core amount.  Hyperthreading is almost guaranteed to lower your performance in anything that matters.

    Ok but dont we have a standered 120mm water cooling fan installed to get rid of the heat? Also (I forgot you this) my target is 4ghz at least.

    On extreme CPU's the turbo boost will raise all cores. Extreme CPU's also have the option to set the value of each core.

    ah, thanks for the tip, wasn't aware of that.

    @OP after looking around, i feel 182x22 is probably going to be your sweet spot for 4ghz and decently clocked ram

    But my ram is rated at 1600mhz and that will force up to 1820 which will cause a blue screen or force down to 1456mhz. If I get that problem sorted I will try your recomendations about my overclock and hopefully get back.

    your ram is rated for 1600?  i'd try something like i did with my desktop, 200 base clock, 19 multi, htt off.  this turns up 3.8ghz with 1600mhz ram, the multi can be flipped to 20 for 4ghz, but i promise that as long as you have the 200 base clock, 200x19 _feels_ better than 4ghz+ utilizing a lower base clock and higher multiplier

    There is another problem guys my base clock wont move in the bios neither up or down
