Intel i7 4790k ram speed limit?

[Guest]

Hello

I have a computer here with the intel i7 4790k CPU in it. (I'm no expert)But by looking at this site, down in the memory section, it says 1333/1600. Does that mean i can't have ram faster than that? Like 2133 and so on...

If you need it, my specs are:
Intel i7 4790k (overclocked to 4,5Ghz)
Coolermaster Hyper 212 Evo (with it's original fan)
Asus Z97-a
Msi GeForce gtx 760 Twin Frozr 2GB (not overclocked)
2x8Gb of Crucial Ballistix Tactical DDR3 1600Mhz
Corsair CX500w
Corsair obsidian 450d (with it's original fans)
Samsung 840 Evo
A Toshiba DT01ACA 2Tb , 7200rpm

And I am running Microsoft Windows 8.1 as the operating system

Hope to hear from someone soon 😀

1600 is the max JEDEC standard speed. Your CPU, as does ANY other CPU, only 'officially' supports jedec standard speeds. Anything above and you would be overclocking your cpu's integrated mem controller. Although your cpu will most likely be able to run higher speeds and required multipliers are available, you won't get any guarantee.

No, it depends first on your motherboard. Will it's BIOS let you adjust the RAM speed? If so, you can turn it up as high as it will go until the system becomes unstable.

Usually people just buy a memory kit rated for a certain speed (e.g. 2133) and then use the XMP profile that the motherboard will recognize and use if you tell it to do so. Then it'll just run at the rated speed with no issues.

A 4790k will take pretty high-end RAM, so if your motherboard allows memory speed specification, just let you wallet be your guide. High speed memory can get pricey.
