I've been trying to overclock my Intel i9-9900K CPU @ 3.60GHz to run at 5GHz. I followed a number of videos online, however in Windows it still says 3.6GHz and in part of the BIOS it also says that. 

In the BIOS I set Ai Overclock Tuner to XMP II and CPU Core Ratio to Sync All Cores. You can see the Target CPU Turbo-Mode Frequency is 5GHz at the top. See page one of my BIOS here https://imgur.com/xVBv8Qi

I set Core 1 to 50 which then synced across all of the other cores https://imgur.com/nujILBg

And then I set DRAM frequence to AUTO to ensure it could keep up with the new processor speed (should I set an exact amount on this?). But as you can see in the Hardware Monitor it still says 3600MHz https://imgur.com/KYxHNFk

My other specs are 64.0 GB RAM / NVIDIA GeForce RTX 2080 Ti

Any help gratefully received! Thanks

A good starting point is to download 2 small freeware programmes. These are CPU-Z  and Core Temp.  Google them. They are well known and widely used and will show you exactly what is going on with your CPU in real time, while you are using it. These items run in small windows which can be set to be 'Always on top'. They have almost zero effect on CPU load.

CPU-Z will also confirm memory settings and Core Temp will give you CPU frequencies for each core and the loading and temperature of each core. Useful stuff when overclocking.

Thanks John. Both Core Temp and CPU-Z show it as 5000MHz.

Do I need to increase my DRAM frequency?

To an outside observer, your questions suggest that you don't really know what you are doing.
I might add, as I also do not, so this is not a criticism.
It looks like you might be better just leaving the CPU alone.
The i9-9900K will run at 5 ghz without your intervention, unless
for some reason your motherboard has disabled turbo boost.
Setting it to run at 5 ghz all the time will most likely achieve little more than generating heat.

You don't say what speed your memory is rated at. I would guess it's probably 3000 or 3200.  Your image of the hardware monitor suggests it may be set to the basic, non XMP setting of 2133.

I would just set memory to XMP setting in the BIOS. There should be a simple option to select this. Further attempts at overclocking memory beyond its rated XMP setting are rarely worthwhile.

The memory page of CPU-Z will confirm the speed of each memory module. It will actually show half the true speed, like 1500 or 1600, but don't worry about that. It's just the way it is defined. 

Beyond that, watch the CPU cooling until you have got a stable system. The 9900k is usually quite happy running at 5.0Ghz on all cores, given a decent cooler.

@BWBriscoe, like you I’m no expert on overclocking. But Pete Dowson pointed me to a program called AI Suite. If you have a Asus motherboard this program will overclock your CPU with no risk to the user.

I have used it to successfully clock 3 virtual processors of my i7-8086K to 4.9 and the other 3 to 4.8. There is a nice performance boost in P3D.

I strongly recommend it if you have a Asus mobo.
