Why is my ram running at 1066 MHz?

[Czuhnul]

Hey all, hope everyone is doing great. I was just looking for some help with RAM, I have the G.Skill Trident Z 3000 MHz. I went into my bios and turn on the DOCP and the clock speed was set to 3000 MHz. After restarting my BIOS stated it was running at 3000 MHz. When I load CPU-Z It says max bandwidth is 1066. Here are some screen shots;

I also check my NZXT Cam software and noticed that it stated I was running at 1066 as well. Here's a screenshot of my specs and NZXT showing its speed at 1066.

I was wondering how to get this to 3000 MHz or if I was doing something wrong as I thought enabling DOCP was the way to get XMP working. Thanks in advanced!

Let me first mention the 1066Mhz means it runs at 2133Mhz.

What I mean by that, is that the 3000Mhz or 2133Mhz base speed is actually MT/s, as DDR RAM can transfer two things per cycle. Making it effectively 1066Mhz, but it can do two things.. So manufacturer just simply label it at 2133Mhz.

 

Anyways, yes.. DOCP is the AMD ASUS equivalent to Intel XMP and should enable the RAM to its high speed setting, but it does often happen it can't find a fit speed profile, meaning you might have to tune the memory yourself.

Set the memory speed to 3000Mhz (or 2933Mhz/3066Mhz which is sometimes the listed speed), set the voltage to 1.35V and set the timings manually yourself according to how they are specified on the memory manufacturer's website. See if it runs stable and you can tweak from there if you like (try to get lower timings for example).

So, I put the speed back to 3000Mhz the voltage is on 1.35 but when i tried to set the timings myself there was no option to do it. I can just look at them but not access them. Ill provide pictures so you can see for, but with this being said, if what I did was "working" should I see a change in my CPU-Z and NZXT software?

what did you do to access them? Normally you could change their values by spamming the + and - key, or just type in the number you want (I use the numpad for this). Arrow keys can't change their values indeed.

Ahh I tried clicking enter thinking it would prompt me a drop down selection like how i changed it to DOCP. Anyway what do I want to change the speeds to exactly? https://www.gskill.com/product/165/166/1536651750/F4-3000C14D-16GTZRTrident-Z-RGBDDR4-3000MHz-CL14-14-14-34-1.35V16GB-(2x8GB)

Do I put it to whats stated here on the site? This is the ram i have

I dont think so, the DOCP profile is what the kit's rated for, which is 3000MHz 16-18-18-38.

Ahh yes on CPU-Z it states my timings are 16-18-18-38, so is my ram running at its full potential? I was just curious if i was supposed to see the 3000 Mhz anywhere on CPU-z or any other program im using.

Yes

some may report 1500MHz instead (data for DDR is transferred twice per actual operating clock cycle)

You can change the timings manually through one of the drop-down windows. I saw it earlier today, but decided not to change the timings.
