Just a Question About Memory Frequency and CPU [SOLVED]

[SrCarcaca]

Hello!

Today I was talking with some friends about Memory Frequency, and CPU.

As you can see, I have one MSI Gamind 3 , i5 4690k and a 2x4GB 1333Mhz.

 

My question:

On the Intel WebSite ( http://ark.intel.com/products/80811/Intel-Core-i5-4690K-Processor-6M-Cache-up-to-3_90-GHz ) shows my CPU have the following support:

- Memory Specifications
Max Memory Size (dependent on memory type)	32 GB
Memory Types	DDR3-1333/1600, DDR3L-1333/1600 @ 1.5V
Max # of Memory Channels	2
Max Memory Bandwidth	25.6 GB/s
ECC Memory Supported ‡	No

 

 

What will happens if I change my 2x4GB 1333 Mhz for 2x4GB 2400 Mhz?

The RAM will work on 1333Mhz or 2400Mhz?

 

Sorry about english, Thank You!

It will initially run at 1600 mhz. Technically 1333 and 1600 are the only speeds supported by Intel, but if you enable XMP the memory will run at 2400 mhz no problem.

you can surely go up to 1600mhz as its officially supported by intel (assuming your mobo can support this speed too)

 

going any higher will depend if your processor and motherboard can handle it

there's a chance they wont work, but they most probably will

Thank You for the fast aswner!

On Benchmark, what will work better? Is possible know without testing?

On nearly all benchmarks, memory speed makes no difference. There are a handful of things that it does make a difference in, like 7 zip, sometimes during video editing, and a very small handful of games. For the most part fast memory frequency makes no difference, but if there isn't a huge price difference then why not.

 

The one thing it does make a huge difference in is when you are gaming on integrated graphics, but I'm guessing you aren't.

on synthetic benchmark, faster ram will win of course

 

in actual load, if your cpu isnt under heavy load, the difference is negligible

but if your cpu is under heavy load, faster ram will give you as much improvement as overclocking your cpu

Really thank you guys! I'll change for 2400Mhz. I'm new here on LTT, and I really enjoing!
