AMD Ryzen 9 5900X speed issues

[NK01UK]

Hi folks I have the AMD Ryzen 9 5900X rated at 4.8GHz but currently both my
A-XMP profiles on my DRAM settings are showing 3200MHz.
Is this the best I am to expect from my current set up or could or should I expect the higher speeds advertised by AMD.

My current specs are as follows:

AMD Ryzen 9 5900X 12-Core Processor
MSi MPG x570s Carbon Max WIFi AM4 DDR4
Sapphire Radeon RX 7600 Pulse 8GB GPU
TUF Gaming 32Gb 4X8GB DDR4 RAM 3200MHz
2 x 480GB Toshiba KIOXIA EXCERIA 2.5" SSD
1TB Kingston NVMe SSD M.2PCIe 4.0
500GB WD Blue 2.5GB SATA 6Gbps SSD
Deepcool AK500 CPU Cooler
3 x 120mm Corsair AR120 RGB 7 Blade fans

Thanks in advance

Read max boost clock. Put mouse onto the black circle with the i for information

I was well aware off max boost clock speeds & limitations. I was expecting at least 1 of my A-XMP profiles to be higher. I’m asking for advice not sarcasm.

That was advise

I’m aware of max clock speeds. I’m thinking my RAM sticks could also be the issue & was looking for some clarification. My max memory speed of my RAM sticks are 3700MHz which tie up with my A-XMP profiles. My motherboard can take up to 5.8MHz so would changing my RAM sticks make any difference? And please no sarcasm

NK01UK,

Please advise as to where you see any sarcasm.
My max memory speed of my RAM sticks are 3700MHz which tie up with my A-XMP profiles.

The link in the reply #2 of Peter shows the specs of the CPU which among the information provided by AMD states that the maximum RAM speed supported by their Ryzen 9 5900X is 3200MT/s.

A CPU must be compatible with a MB whereas the RAM has to be compatible with both the CPU and the MB, this because a MB can be compatible with faster CPUs than the one in your list of parts and MB manufacturers often state RAM speeds that far exceed that which any compatible CPU can handle, this is misleading at the least or dishonest at worst.

Short version, it is the CPU that dictates the maximum speed of the RAM and not the MB.

Wow that’s a lot to take in. What would your humble advice be in my situation. Right now my PC is getting pretty sluggish, high end games are glitchy at best, so I’m not sure what to do

Not a fan of it personally but manually overclocking the RAM and CPU together is the only way.

Fwiw, I am of the opinion that XMP is nothing but a gimmick/sales ploy to make end users feel that they are getting something extra for free, they are not, RAM manufacturers know full well what their products are capable of and should just advertise the stuff at the maximum that it is capable of, non XMP RAM is available that will still work at 3200MT/s but it does tend to be in OEM brand computer like Dell and HP etc.

So my best bet is to invest in some decent RAM sticks at 3200MT/s & go from there? I’d probably need some help with the overclocking as I’ve never done it before.

Must admit that I’ve not seen such RAM but you look to already have the appropriate, any chance of a link to the RAM that you have so that we can take a look.

As said not a fan of OCing as I’ve spent too much time over the years repairing bad overclocks, best I can do is suggest that any guide that you follow is from a reputable source such as the one here and avoid the online antics of the likes of smoking joe who has money to waste.

Also Phil what is the correlation between MT/s & MHz. AMD appear to be confusing matters. Which unit of speed should I be looking at?? Because hypothetically
[HEADING=2] Crucial Ballistix 2x32GB (64GB Kit) DDR4 3200MT/s CL16 Unbuffered SODIMM 26 goes for £329[/HEADING]
whilst
[HEADING=2]Corsair Vengeance LPX 64GB (2x32GB) DDR4 PC4-25600C16 3200MHz Dual Channel Kit (Black) goes for £139[/HEADING]
so which unit of measure would I go for??

MT/s is claimed to be a more accurate reading of RAM speed.

You already have RAM that is appropriate for your CPU, note the SPD speed and the tested speed.

OK that’s good to know, I wasn’t looking forward to overclocking CPU’s & RAM sticks. I might go ahead & reinstall windows & see if that clears any of the sluggishness. I’ve already done the usual updated drivers etc etc. But I will report back once I’m done & we can go from there. But at a glance for general home office use & for my son who play high end games on the PC is my set up “ok”? Or could it be improved??
