Ram speed 2133 or 3000

[MozarT 👜]

so i have a Z270F motherboard with a I7-7700K kaby lake but my ram speed is at 2133 should i turn it up to 3000 or does it not matter in gaming performance

It can bring some extra performance, but generally it doesn't matter on Intel cpus that much.

At the very least set XMP to your RAM to run it at it's advertised speed

The CPU only supports up to 2400, keep it at 2133 where it's stable. The gain from that OC would've barely been measurable.

okay thx guys :)

BS. The CPU doesnt support it but the motherboard. and of course will 3000MHz be stable if the RAM is rated for it. espacialyl through XMP overlocking. And the gain is emasurable. not only a little but highly depending on the game/program.

Just enter Bios - and load the XMP profile - save and exit

not sor hard, simple and trouble free.

The CPU tiself not, some games and programs do. ARMA III is one of the grand examples that profit a lot from faster RAM.

If the ram you purchased was indeed rated for 3000. Just enable XMP profile. Intel systems also benefit from high speed ram. But if you purchased a a ram that was rated for 2133 chances are you are being stable on 3000 is pretty low.

Intel itself does not profit much from Ram OC unless you do it manually. Most 2133 MHz RAM can be overclocked just fine. You just have to raise the voltage from 1.2 to 1.35 and play with the timings.

BS. The CPU have a say in it. Yes, you can OC it to get it to run a wee bit faster but without tweaks, the CPU would run the RAM at its highest supported speed.

DDR4-2400 will have an actual noticeable performance boost over DDR4-2133 in Duel Channel mode on Intel CPU’s and Chipsets.

the cpu imc is rated for 2400, but can easily run 4000+

boot to bios and select the xmp profile for 3000

[Bad 💀 Motha]

Enter the BIOS and enable DRAM XMP Mode

You are not always guaranteed to reach XMP speeds. It is afterall an overclock. Speeds such as 2400 to 2800 are more easily achievable but you will not always be guaranteed 3000 Mhz plus.

Regardless, if you have memory rated to run at 'X' speeds when using 'XMP' you want to set it. If you see it's not stable just push back the MHz just a bit.

However, if you are asking to set it to 3000 MHz despite your memory not being rated for it it's not that simple. It takes time and effort to overclock your CPU/Memory/GPU.

well my Ram is 3000mhz they are just running at 2133mhz

OP, there isn't anything stopping you trying it to see what happens. It's the only way you will really find out.

The performance impact depends on your cpu, gpu and ram speeds and the game. Usually one wouldn't overclock ram unless the cpu is overclocked and, importantly, the gpu has the spare performance to benefit.

Of course you will always be able to reach XMP speed with I tell. Just not with AMD as they use AMP instead.
If they don't teach the speed you can always RMA ...
