[SOLVED] Can't get RAM to go at right speed!

[mirandarobertson1972]

Hi all
Turning to you wise folk after hours of toil and strife.
I've built a new PC using my old hard drives. It has an MSI M5 Z170-A motherboard, Nvidia 3060 GPU, Intel i7 6700 CPU and my RAM is NETAC DDR4 3200. But try as I might, it won't let me change the speed from 2333.
I have tried backdating the bios and it still happens.
I've tried two ways to get it at the right speed - XMP and manually selecting the right speed. It then boots up and tells me the overclock failed and it's reverting to default settings.
What haven't I done here?

I guess it could be possible that the NETAC brand may not be quite compatible with your MSI mobo above 2333mhz. Do you have any other DDR4 3200 to test with ?
Thats a stab in the dark.

I don't have any other sticks to test it with, no. Dratted thing!

Is your ram a two stick matched kit?
Unmatched ram may not work well.

Have you overclocked in any way?

If so, set the ram speed via xmp first.
On older chipsets, there is an interaction.

Can you post a cpu-Z report of the spd and memory tabs?

Setting speeds manually, try increasing the ram voltage in the bios a bit past what the xmp setting says is required for 3200 speed.

Lastly, do not worry too much about ram speed.
Excepting integrated graphics, the actual app performance difference is small.
Think a few %.

They are matched, yes. You think I shouldn't worry about the diff between 2333 and 3200 then?
Having to put now but will get that report when I'm home.

I would worry a bit only because you do not seem to be able to do what you should.
Here is an older ram scaling analysis using haswell E and DDR4:

You could run memtest86 or memtest86+
They boot from a usb stick and do not use windows.
You can download them here:

MemTest86 - Official Site of the x86 Memory Testing Tool

MemTest86 is the original self booting memory testing software for x86 and ARM computers. Supporting both BIOS and UEFI, with options to boot from USB.

Memtest86+ | The Open-Source Memory Testing Tool

Memtest86+ is an advanced, free, open-source, stand-alone memory tester for 32- and 64-bit computers (UEFI & BIOS supported)

If you can run a full pass with NO errors, your ram should be ok.

Running several more passes will sometimes uncover an issue, but it takes more time.
Probably not worth it unless you really suspect a ram issue.

Thought.....matched and matched kit are 2 different things.

Good point.
By matched kit, I mean one kit of two sticks bought in the same package.
Two separate identical part numbers are not matched.
The internal workings and even chips used can be different.

They did come in the same packet, so I blooming well hope they are a pair!
Sorry I haven't come back to this thread. I ran out of weekend to sort this out.
