It says 2133 on the BIOS page I showed you there, but in CPU-Z and task manager it still says 800 and 1600 respectively. I cannot see any XMP profile 2, just [disabled] or [Profile1]]

You might need to update the bios on your motherboard if there is an update for memory compatibility. Find your bios version in CPU-Z on the mainboard tab or in the bios.

That's bizarre, DDR4 native speed is 2133mhz (meaning showing as 1066 in cpu-z and the like)

It should NEVER run below that and its something I've never seen before.

As suggested drop in bios and enable xmp

I'm not the best with computers. Once I get into BIOS, all I need to look for is XMP and enable it if it's disabled?

Yes, on the MIT tab select advanced memory settings option.

Then extreme memory profile from there and set it to profile 1 (it absolutely will be disabled if you've never enabled it)

Hopefuy that will get you 2666mhz speed automatically , if it doesn't come back and we can walk you through manually setting it.

It was disabled. I changed it to Profile1 and didn't touch anything else, made sure to save and exit properly. Still on 800MHz according to CPU-Z

Excuse the bad picture, don't know how to else to take a screenshot of BIOS. It seems to say 2133 not 2666?

You may have to enable an advanced mode or expert mode to modify timings and speed settings. I don't know what the rest of the bios looks like, so I can't really guide you with that, but mode would probably be enabled on the previous page.

Played around for quite a while and cannot find anything. Harder than I thought this was going to be lol.

Any further assistance? Thank you in advance.

To start with, DDR is Dual Data Rate so when it says 800/1600 that's the same thing. Some software reports Data Rate, some reports Dual Data Rate. I've never personally seen DDR4 run at less than 2133MHz (1066MHz). So this is something new. Can't even claim its a hack-job from someone swapping heatsinks etc, because they couldn't get DDR4 less than 2133MHz either.

You gave cpu-z, no worries for Intel. Good part is it identifies your exact motherboard. Go to Gigabyte website/support and there you'll find 2 things. Bios and chipset drivers. Well 3 things, you'll also find detailed instructions on how to upgrade the bios. Follow those exactly. Do not deviate, do not turn off the pc until told to do so.

After that, installing the chipset drivers is pretty easy.

This is my motherboard and the drivers page. I'm confused, there's so many different options there and it also has this warning at the bottom which is putting me off. Should I just download the newest one? 22F

Warning:
Because BIOS flashing is potentially risky, if you do not encounter problems using the current version of BIOS, it is recommended that you not flash the BIOS. To flash the BIOS, do it with caution. Inadequate BIOS flashing may result in system malfunction.

Before updating the bios, enter the bios and go to the M.I.T menu. Go to the Advanced Memory Settings menu and change Memory Timing Mode to Advanced Manual. This will allow you to change memory timings and other settings so you can manually set your ram to 2666 to see if it will work. It may automatically use the timings for that speed programmed into the modules, but for no leave the timings on default or automatic. If 2666 fails, then you should flash the bios to a newer version.

Edit - I would also suggest either resetting the bios by removing the battery or jumping the cmos reset pins or try loading optimized defaults in the bios (F7 key) before flashing the bios.


Flashing the bios is easy and is only a problem if you have a corrupted bios file (not really an issue if you have no hard drive issues) or if the system loses power during the flashing process. Your motherboard has duel bios, so if something goes wrong during the flashing process you should be able to recover without issue and start the flashing process again.

I would recommend starting with Bios F22a before moving on to F22f, if ever. You need a good USB flash drive formatted to FAT32 and you place the bios file directly on the drive. Reboot the system and press the END key on the keyboard when booting to enter the Q-Flash flashing utility.

Follow the instructions on screen to select the bios file (the file should still be named Z170XG5.F22a) and complete the flashing process. After it completes it will either reboot for you or prompt you to reboot. After rebooting, enter the bios and pres F7 on the keyboard to load optimized defaults, then press F10 to save and exit the bios.

Let the system boot to Windows and make sure everything is working fine before rebooting again to enter the bios and enable XMP to see if it works now.

Hi, thanks for your effort in attempting to help me. I went into the BIOS and I changed 'Memory Enhancement Settings' to 'Enhanced Performance' and I also changed 'Memory Timing Mode' to 'Advanced Manual', but I wasn't sure what to do next as I don't want to play with things unless I know it's exactly right. So where/what should I be editing now that advanced manual mode is on? I included a picture below, sorry again for the bad quality.

Not sure what the enhanced performance setting did either, but I put it on anyway as I assume it can only benefit my PC.

You have to adjust memory multiplier (from 16 to 20), so memory frequency changes to 2666mhz.
Might be necessary to disable XMP. It seems like XMP is not being applied properly.

Ok thanks. I’m away from my computer now but from memory I don’t think that part where it says 16 was editable but I’ll double check when I can. Only parts I could edit or change were the ones that are highlighted more white. Also out of curiosity, if I do manage to fix this issue, will my computer have any actual noticeable performance increase or not really?
