Hello guys,
i've been recently rebuilded my computer after a trip, and now im thinkin that something is not right, so here what i have and my question...
My ram, G.Skill Trident Z RGB 16GB DDR4 3200MHz (check pic for more info) i believe they are not well setted, my problem is that im not very knowledge about this kind of things but im willing to learn, by opening CPU-Z i've noticed the DRAM frequency running a 1600 mhz while the NB frequency is 4300 mhz, im confuse about it, is there anything wrong? cause i've been having more problem multi tasking things in my computer :\.
Thanks in advance.

It's not running the speced timings though. Did you enable XMP?

It seems like you've entered 3200mhz manually without enabling DOCP/XMP, CL17 is very high for 3200mhz.

CL17 is a bit high, but not very high.

There's plenty of memory sticks sold as CL16 these days, and cheap memory sticks are CL18 or higher.

 

@Petwire, your memory sticks are designed to work with memory timings 14-14-14-34 and 1.35v, as this page shows: https://www.gskill.com/product/165/166/1536653463/F4-3200C14D-16GTZR

You're currently using them with memory timings 17-18-18-36 and 1.35v, which are probably the default timings.

You can squeeze a tiny bit of performance (probably under 0.5%) if you go in bios and manually configure those parameters (you can see the names for those in CPU-Z picture) to 14-14-14-34. 

Alternatively, you can see if enabling XMP / DOCP with the 3200 Mhz preset / template will configure those parameters for you

 

Or you can leave it be, like i said it's not some significant performance increase and maybe you don't care that much about it. 

Either way, this isn't the reason your applications cause problems.
