PC Novice, switched to Ryzen Build, Subpar Results

[MangaCarta]

Hello everyone,

 

Firstly, I am not an experienced PC builder.  Yes, I have built my own PCs, but I am very little experience in maximizing my systems to reach their potential.

 

Now to the point...

 

Up until yesterday, I was running a build containing an i5 4690k with an MSI Gaming mother board and 16 gigs of DDR3 RAM running at 2444 hz, with a 1080ti.  I have an Acer Predator 165 hz, Gsync display. This build was doing fine until I started to play Battlefield 1 and 5.  I was getting abysmal FPS results, stuttering and frame rates anywhere from 90 all the way down to 40 depending on the resolution (1080p vs. 1440p).

 

Black Friday came around and I decided to upgrade my main components.  I look online, and the Ryzen 7 2700x was getting anywhere from 130 fps to 170 fps depending on the resolution.  I decided to bunker down and purchase some new components.

 

Yesterday, I installed the Ryzen 2700x along with an Asus ROG b450-f motherboard and paired it with a single 16gb stick of Corsair Vengance DDR 4 ram which is rated at 3000hz.

 

I did a clean install of Windows and tried out Battlefield 1 again.

 

Unfortunately, it is not meeting my expectations.  I have an improvement now, as FPS is now usually above 100, but I never get anywhere hear a consistent 144fps, and the frame fluaxates big time.  When there is alot of stuff happening on screen, I even dip below 100 fps at times.

 

Again, I am not very experienced, but I know I should be getting more out of my system compared to the benchmarks I have researched.

 

Does anyone have any ideas at all to improve performance?  I am able to provide any diagnostic data if you point me in the right direction.

 

On a final note, I am running the Prism Wraith cooler included with the Ryzen.  Thanks in advance.

that's some slow ram right there. 0,2444 mhz

 

btw, you have single channel ram. maybe 2x8 will help you out?

Ryzen doesn't like single channel RAM. Always buy RAM in pairs.

Only one stick of ram? May have wanted to buy a 2 x 8GB kit for dual-channel support. A 2700x + 1080 Ti is what my build has and I don't have that kind of stuttering in any of my games. granted I also have a 4 x 32GB kit of DDR4-3200 but even when I was running 2 sticks I didn't get more stutter than I expected.

Read the entire thing

my bad

 

Yes, single channel RAM on Ryzen is a big performance breaker

I run BFV on my 2700X and 1070Ti combo at 1440p and it's buttery smooth for me in 64 player conquest. Works rather well

Is it really as simple as the RAM?  Seems crazy that switching to dual channel will bump up fps by like 30 %.  I am trying to maximize the performance as much as possible...ideally I want a stable framerate but it is not possible right now at all.  It is a mess.  I do have another 16gb coming (8 x 2).  The ram kit is rated for 3000hz if I overlock it in the bios.

 

Any other ideas on how to maximize the system?  Anything in the bios I should be aware of which can make a difference?  This is my first AMD build so I feel like a toddler lol.

It's one of the notable differences between team red and team blue. On Ryzen you need to watch your memory as it impacts performance much more than on Intel cpus. 

 

You can try overclocking your ram but compatibility has also been an issue on Ryzen, especially at higher speeds of memory.

 

It seems to balance out very close in the end money wise. Intel platform have more expensive cpu and mobos, but then AMD you have to spend more on memory.

What about the CPU itself?  I heard the 2nd generation ryzens boost automatically, but the max I see is 3.9 hz.  Is there a way I can track this or push more performance out of it?  Anyone familiar with the ASUS ROG bios?

Two sticks of RAM is generally recommended for Ryzen builds just because infinity fabric works a lot better with it - as others have said Ryzen is very sensitive to RAM speeds and dual channel 3000-3200MHz is generally the sweet spot, can go higher but the returns aren't worth it - also for a Ryzen 7 I would've gone for an X470 chipset mobo as it's more geared towards Ryzen 7 rather than B450 but I think that's more opinion than fact unless someone else wants to chime in.

 

As for ASUS ROG bios - it might help to put the performance enhancer setting to level 3 (OC) and see if that helps. Generally, I would recommend manually overclocking because the PBO and XFR2 can be pretty stupid sometimes where voltages can spike up to ~1.47v and even 1.5v sometimes. I just set my 2600X to 4.0GHz all-core OC at 1.24v. Apparently the ryzen 7 2700(X) also overclock at similar voltages on Asus ROG boards at least (1.24-1.25v for 4.0GHz OC and 1.38-1.42v for 4.1GHz OC) but take all this with a pinch of salt as silicon lottery also has a part to play here.
