RAM bus speed for 5820K

[Sarfaraz Abdullah]

Hi!

I am gonna buy a PC. My preferred processor is core i7-5820K. So, with that, I'll have to buy a LGA2011 v3 socket consisting motherboard and DDR4 RAM.

Now, from intel website, I see that the memory types supported by 5820K processor is DDR4 1333/1600/2133. So, shouldn't it mean that the highest RAM bus speed I can allocate with 5820K is 2133 MHz?

http://ark.intel.com/products/82932/Intel-Core-i7-5820K-Processor-15M-Cache-up-to-3_60-GHz?q=Intel® Core™ i7-5820K Processor (15M Cache, up to 3.60 GHz)

Help is appreciated. Thanks in advance.

That is not RAM bus speed, it is RAM frequency. No matter the RAM you get, the frequency will cap at 2133 MHz, so there is no point for 2400+ MHz. If you want stability, get 2400 MHz RAM and downclock it to 2133MHz. BTW, RAM frequency is not really important, you will not notice the difference between 1333MHz and 2133 MHz, unless rendering, and there will be 5% difference AT MOST, so get the best RAM based on price/GB and you are good to go. If you OC FSB, you may squeeze little bit out of your RAM, but PCI-E will lose stability, so do not do it, it is not worth it (unless you are on a competition xD). Hope I helped.

Why are you using the word BUS so much? There is no more BUS on Intel since X58 8 years ago.
The supported RAM listed by Intel is only the "JEDEC" spec RAM that is supported by the CPU. In reality, the CPU can support much faster RAM than this typically up to about 3000Mhz. However, fast RAM is cost prohibitive. A nice bang/buck segment right now is 2400 and some 2666. Remember to buy 4 identical DIMMs as X99 is a quad channel platform.

What motherboard are you thinking of buying? Right now Tom's Hardware's ratings have the ASRock Extreme 4 X99 in first place. Go to the front page then go to Motherboards and click best/top motherboards to read the article.

BTW, why at hell is 5930K so much more expensive than 5820K!?

Why are you giving nonsense advice is a better question? You clearly don't understand how RAM support works so why are you providing anwers, wrong answers, at that, in a thread about RAM support? It'll cap out at 2133Mhz? Are you ok?

If he OC's FSB?? You actually said that in an X99 thread? There hasn't been an FSB since 2008 dude. Seriously. You are so utterly and clearly not ready to provide answers. I don't understand why so many people on this forum feel inclined to do so without the requisite knowledge. It's ridiculous. Truly, it is the blind leading the blind.

I'm not going to tell you why the 5930K is more expensive. You can look that up while you're researching

Come on, why does everybody need to stop my trolling??? Fuck you all!!!

i have an asus x99-s, i7-5820k and 16gb of 2400MHz ram.
What i think it means is thats what will deffinatly run with the processor, when i got my build up and running it down-clocked my ram to 2133MHz, i think this will happen factory on any mobo/cpu, there are settings to set it to what you want/overclock really easy and no stability issues like previously mentioned
hope this helped
