cpu bottleneck

[Seth12301459]

Alright so i have a ryzen 3 3200g paired with a gtx1080 and i know my cpu is bottlenecking the gpu and i have ordered a ryzen 5 5600x but my problem right now is that when playing something low demanding like minecraft my cpu will sit on around 50% and gpu on 7% but my fps is extremely low i dont quite understand why my cpu wont max out and im on low frames, this is the same case in other games such as borderlands 3 and resident evil 2

If you look at per core cpu use, one core is probably maxed out. To keep it simple, if you have two cores  - one at 100% and one at zero %, it will show as cpu = 50%.

Just to get the obvious stuff out of the way, is your monitor plugged into the GPU and not the motherboard? If it's not, then that would be why your FPS is so poor, it's using the iGPU instead of your 1080. 

 

That said, Minecraft is a very single threaded game, and I would not be surprised if you just had one core maxed out. The 3200G should be fast enough that you're getting passable FPS in Minecraft though, so look at the clock speeds of everything to see if there's something going wrong.

To build on what @Blue4130said. You can check for this with either HWinfo 64 in sensors only mode. That will show per core utilization. 

Task manager will also show it, but isn't the most reliable.

i do have a bit of a idea at what im doing i only used minecraft as a example cause it was the easiest to make a example of and i checked all cores are running at the same none max out. yes all 3 of my monitors are plugged into the gpu. the core clocks look about right to me.

im aware of that and i have checked for that my cpu is using all cores

this was resident evil 2 i screenshoted this on

In that screen shot it seems like it's working as intended. There is a pretty big CPU bottleneck, but the GPU running at ~60% is about what I'd expect

[IkeaGnome]

Enabling XMP might help a bit with the CPU. What speed is your ram? It's running at 2666 mhz right now.

i get that what i just dont understand is why the cpu cant get to 100% it never gets about 80%

preety sure i have docp enabled(docp bieng the amd version) and yes it is 2666mhz

As @IkeaGnome alluded to, you might be memory bottlenecked. 2666MHz is pretty slow for DDR4, and running that can hurt the performance quite a bit.

as im upgrading to a ryzen 5 5600x im assuming the performance will be hurt even more. is there any way to know it is a memory bottleneck

Not necessarily, the 5600X has a lot more cache and faster cache so the memory performance actually doesn't matter as much. It still benefits from faster RAM, but it doesn't benefit quite as much as the 3200G would benefit.

 

Main way I know of to tell if it's a memory bottleneck that I'm aware of is to just overclock the memory and see if the performance is any better. Unless you've got Hynix AFR or Micron Rev A, you should be able to hit 3200MHz CL16 without too much trouble.

im on a asus prime a320m-a mobo and ive looked in the bios and i cant change the dram speed but i know in the past i have overclocked it but after having to reset the cmos i didnt overclock it again but im just not quite sure how to overclock it and what to change

The last ASUS board I've used somewhat extensively is a Rampage III Formula, so I don't really know how they've laid out their memory OC settings on that board. 

 

Still, odds are when you up the CPU to a 5600X, it won't be as dependent on memory speeds because of the 8x larger cache and should run pretty well at 2666MHz. Wouldn't recommend buying that slow today, but that chip should be fine with it at those speeds.

haha yeah ive had this pc for around 3 years i bought the cpu within a few months of its launch date

 

i was just in the bios and i was reading the info on the dram speed and it said +.005 increments so i pressed 0 and its letting me overclock the dram speed now i went from 1.2 to 1.205 and it booted up fine is there any other settings i need to change

Pretty sure you're changing the DRAM voltage. You can up it to 1.35V (so either set it to override 1.35V or do an offset of 0.15V). You would also need to change DRAM frequency to something higher like 2933MHz or 3200MHz, though depending on your CPU 3200MHz might not be possible (Zen+ had a pretty weak memory controller). You can also try tightening some of the timings, CL16-18-18-38 should be very achievable at 3200MHz or 2933MHz. 

 

Still, if you're gonna put in the effort to overclocking your memory, I'd wait till you've got your 5600X. The Zen2/Zen3 is much better than the Zen+ controller, and whatever memory settings you find are stable on the 3200G will be next to meaningless on the 5600X. Proper memory overclocking does take forever, so if you're gonna do it, wait till you've got the new chips before devoting the time to it.

the max my cpu will go to is 2933MHz i looked on the amd page. im not gonna have much use for my old cpu when im done with it so ill most likely sell it on ebay and get a 3200mhz kit that is docp capable unlike my current ram thanks for the help.

I'd run 2933 in the mean time. A small improvement, but it's a "free" improvement. 

Once you get the 5600x, I'd hold on to that RAM and see if you can OC it to 3200 mhz. You might not even have to get a new kit.

Ryzen DRAM calculator will help

And to find which memory chips are on the RAM, you can use Taiphoon Burner.

already tried it and my ram will not overclock to even 2733, stops posting when overclocked or it takes about a minute to and loads into windows and crashes soon after

Once you have the 5600x, I'd try again before you get rid of that kit. The memory controller on it is much better than the one in the 3200g.

ok well im just trying it again i upped the voltage to 1.22 from 1.2 and its running stably i had memtest going for 10 mins and no problems im gonna keep trying to get a little more speed and see what it does

so im at 1.24 volts on dram and 2733mhz and its running stabily now thanks for the help

also ive tried using dram calculator but i cant select most the options and my ram is not xmp so i cant select that and it just doesnt work right
