Can someone explain the difference in RAM MHz.

Seduced Senpai · Nov 17, 2015

I am looking at buying the Corsair CMY16GX3M2A1866C9R Vengeance Pro Series 16GB (2x8GB) DDR3 1866Mhz CL9 XMP Performance Desktop Memory Kit Red but am curious whats the difference in Mhz.

So whats the different in 1866Mhz and 2400Mhz?

The 2400Mhz is actually cheaper than the 1866 so is it worth getting 2400?

1866 Mhz on Amazon: http://

2400Mhz on Amzon:

does your board support 2400 ?? then go with it the rule is faster is better ??

I use 1600 and works just fine

Actually the big thing will be the MC (memory controller) of your CPU more than the mobo, a mobo often can easily run 2800-3000, but if you have a non-K CPU chances of running 2400/2666/2800 will be slim.

Both your links go to the 1866 set, but if the 2400 set is the same model it is prob the 2400/11 set so it would be the better of the two performance wise - if you are looking at a 2400/12 might consider the 1866/9 set.

Well the motherboard I will be using is the ASUS Maximus Ranger with a Intel i7 4790K CPU

Tradesman1 · Nov 18, 2015

With a K model CPU the 2400 is the better choice, a non-K might not be able to 2400 sticks at 2400

Ok so if I get the 2400mhz will I have to do anything in the motherboard settings?

Or can I just plug it in and it will work?

Tradesman1 · Nov 18, 2015

2400 might require a small CPU OC, but first simply try going into BIOS and enable XMP, select profile 1

junkeymonkey · Nov 18, 2015

I agree if your using a ''K'' chip and the 2400 is priced right as you say from what the 1600 is go for it and set the xmp and let 'er rip

I guess I need to remember to ask about the ''K'' chip being used -- sorry that leads to me giving bad info with out knowing

Tradesman1 · Nov 18, 2015

No worries, there's a ton of people out there that still it's ONLY the mobo that determines what DRAM speed you can run, and that went out when they moved the MC from the mobo to the CPU about what 6 or so years ago (and even then it wasn't fully true

) I get into this and more in my FAQs and Fiction article (links to both parts here:

true but I tend to go with if a non ''K'' chip stay with 1600 max [but that's just me ] the chips are rated for over 1600 that is considered overclocked and if the chip needs a bump for stability the non k may not give you this [of course you know all that i'm just putting it out there ]

then even with a k chip there still no guarantee it will achieve 2400 and stable.

That's just their base specs, which are underrated for the CPU, they finally gave in and have published lists of DRAM that has been certified with their CPUs using XMP, think it runs up through 3200 or better:

http://www.intel.com/content/www/us/en/gaming/extreme-memory-profile-xmp.html

listed both in PDF and Excel

yup, all good right up to the foot note

1Warning: Altering clock frequency and/or voltage may: (i) reduce system stability and useful life of the system, processor, and other system components; (ii) cause the processor and other system components to fail; (iii) cause reductions in system performance; (iv) cause additional heat or other damage; and (v) affect system data integrity. Intel has not tested, and does not warranty, the operation of the processor beyond its specifications. Intel has not tested, and does not warranty, the operation of other system components beyond their industry standard specifications. Intel assumes no responsibility that the processor and other system components, including if used with altered clock frequencies and/or voltages, will be fit for any particular purpose.

regardless of all they hype and say the bottom line is overclocking is all your own risk and the key phrase in that '' Intel assumes no responsibility ''

anyway folks been doing it for years and can come down to how well all your components work together

That's their CYA statement alright, gives them an out to deny RMAs to those who say silly things like 'yes I tried OCing to 7.3 using LN2'

junkeymonkey · Nov 18, 2015

well thing is if I had a K chip I would do as you said above -stick it in set xmp and run it and see how stable I say theres a 98.5% chance it will work with out issue [theres all ways a 1.5% chance of getting the lemon some how ]

''That's their CYA statement alright, gives them an out to deny RMAs to those who say silly things like 'yes I tried OCing to 7.3 using LN2' ''

its for anything over what intel lists in the specs [1600 on his chip ] that's what it means
