Solved AMD Ryzen 9 5900X speed issues

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.

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.

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.

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.

For the intended use the present hardware is a good balance but we could do with knowing the details of the most important component in a PC, can you post the brand and model name or number of the PSU..

Glad to hear that you are not keen on OCing as it opens up a whole new can of worms, for optimal performance AMD recommend a liquid cooler for the present CPU but you have a perfectly good cooler that will suffice, any OCing though would require a liquid cooler and coming with that is additional maintenance and the risk of leaks.

Some tips on improving PC performance and health.

Install Windows on its own boot drive or partition on a larger capacity drive, any drive or partition needs to be a minimum of 250GB.

Maintain plenty of free storage space on all drives or partitions, example, on a 250GB SSD boot drive always have at least 38GB free and on a data only 250GB drive or partition maintain at least 25GB free.

Don`t use any third party AV or Firewall, Windows own are amongst the best performers, are free and won`t cause conflicts.

Avoid using VPNs and anti cheat programs if at all possible, the former interfere with internet connectivity and performance and the latter are known to cause conflicts, both cause lag.

Never update drivers for no reason, see my canned info below.

Once Windows has been installed, you install the necessary drivers for the MB and other hardware and then leave well alone, drivers should not be allowed to auto update and you should never update any driver/s unless the new drivers are intended to resolve a specific issue that you are having, installing new drivers unnecessarily can actually cause you the very issues that any new drivers are intended to resolve and uninstalling the new drivers may not resolve the problem/s that installing the new drivers has caused.

Depending on priority it can take many months before the driver provider releases any fix and depending on the age of the hardware or software concerned they sometimes do not even bother or may have already announced an end of support.

The exact same policy applies to the BIOS, do not update it unless it is advised by the manufacturer of the hardware or alternatively if it is to allow for a CPU upgrade.

Updating things for no reason has a 50/50 chance of bricking your computer, don`t gamble unless you can (A) Do without the computer (B) have loads of spare cash and can buy a new one with no problem or (C) Both of the previous.

I only saw Deepcool AK500 CPU Cooler in any event

While Cooler Master is not a brand that I use or suggest as long as the V850 is still in warranty it is perfectly fine for this build, if you were to upgrade the GPU though upgrading the PSU as well may be in order.

Just a heads up, DDR6 is due either later on this year or early next so if you can hang on the DDR5 hardware prices will start to come down.

You are welcome btw

Being that the OP revisited the forum but left no follow up this thread will be marked and closed.
