My brand new Ryzen 9 5900X is underperforming in games

[keshavcolonel]

I've recently upgraded my AMD CPU from Ryzen 7 2700 to Ryzen 9 5900X.

My Ryzen 9 5900X is performing worse than my Ryzen 7 2700 in games such as Valoant and CSGO. I used to get 180-230 Fps in Valorant on Ryzen 7 and now I'm getting 60-145 Fps on my Ryzen 9.

I have 4 sticks of Corsair LPX 8 GB DDR4 3000Mhz memory (32GB of RAM) and one AMD Radeon RX580 8GB GPU installed in a GIGABYTE B450m DS3H v1 mATX motherboard.

I've also upgraded my CPU cooler from Wraith Spire to a Silverstone PF240 AIO assembled in a Silverstone FARA H1M case.

I have never touched Ryzen Master and never overclocked anything in my PC. I've also never enabled XMP profile in bios.

Also, CPU-Z shows that my RAM is running at 1066.4mhz speed.

Please help me get the Fps one should get from a Ryzen 9 5900X.

Did you update your BIOS after swapping the CPU?

Update BIOS, put XMP on, and enable PBO

 

I suspect you're running the 5900X on base clock, yet your performance is really very bad

Yes. I've updated the bios and PC is able to boot into windows with Ryzen 9.

In that case, and since you did not enter BIOS and do any modification, try resetting the BIOS to recommended default settings so the settings are what they should be for the 5900x.

Enable XMP to have the RAM run 3000Mhz. It's running 2133 now (1066 times two cause of Double Data Rate).

 

Also, that motherboard has a weak VRM and it's not even cooled. It was limiting the 2700X in some situations and it does limit the 5900X substially.

Also, the 240mm AIO doesn't help, that's the bare minimum for a 5900X. A decent AIR cooler (dual tower) or a 280mm/360mm would be recommended.

I'm running at stock settings and my CPU has idle temp of 38 degrees C. It gets around 60 degrees when playing games.

Double check or triple check everything the others said then if that doesn't work you can try reinstalling gpu drivers.

 

Personally I got double fps going from i7 7700k at stock settings vs 5900x at stock settings, most notable fps you should look at is minimum fps though.

the auto oc is just a bonus 

using curve optimizer negative: -20 magnitude (after you have fixed all the problems mentioned by the others above) will net you a cooler cpu and free turbo boosting headroom.

 

Make sure you have all the motherboard chipset drivers that you need. Some of them can be really helpful.

I won't be able to change any PC parts at the moment but I will definitely enable XMP settings in bios. I will also try to add more 120mm case fans for cooling if that will help.

Cooling affects your temps, not your fps (unless your cpu is throttling because it reaches 95 or more).

Using the curve optimizer in bios at negative -20 magnitude will affect your cpus a whole lot more than another 120mm fan.
It could bring temps down by 5c or more.

Sure. I will definitely give this a try.

Yeah, Zen2 and zen3 has the Infinity Fabric (CPU interconnect technology) speed connected to the RAM speed and works best when it's 1600 to 1800 (having RAM at 3200 to 3600). Having RAM run at 2133 has the Infinity Fabric probably set to 1066 and that severely bottlenecks a beefy CPU like the 5900X.

Enable XMP. You'll get a nice boost. 1500 is a lot more than 1066.

 

Having more case fans is not a bad idea. Especially if you could have a one directly blow onto the VRM.

I recently built a 5900X and have pretty decent performance with no OC. I found that RAM overclocking was turned off by default and had my RAM running at 2666 Mhz, similar to your situation. FYI - it really isn't worth saving the money using a B450 board, I used the Asus Tuf B550 PLUS and even though it does the job, I'm told the X570 chipset is much better for Zen3. As someone has mentioned, update the BIOS for good measure, and enable RAM overclocking (EDOC, I believe it is called). 3000 Mhz RAM is better than 1066 Mhz, but 3200-4000 is even better with the Zen3. Also, be sure your package temp is below throttling range -- if the CPU package temp is routinely spiking to 90+, that could be a problem also.

There's no performance difference from 550 to 570 motherboards (unless you need extra cooling for ram or other eccentric things).

Main difference is having more usb 3.0 (or better) headers. I would imagine you both have pcie 4.0 

 

Also going from 3000 mhz ram to 3600 mhz ram is around a 3 fps difference. This is more noticeable for work programs not for gaming.

There's plenty of benchmarks about this on youtube but few seem to know about it.

Any updates? 

What did you do to fix the problem?
