Lower Temps and Power On Your Ryzen 7 5800X CPU Without Losing Gaming Performance

the ryzen 7 5800x is an excellent eight core cpu on the market right now it delivers impeccable gaming performance and also does well in productivity apps however early pricing issues aside if there was one area that deterred customers from picking up this chip it was due to the hot temps and high power consumption i'm here to tell you that there is a way to lower temps and power without sacrificing gaming performance let's discuss that in this video hey if you enjoy content like this drop a like make sure to subscribe and smash that bell so you never miss another video [Music] hey what is going on guys danny here welcome back to the channel and i hope you've all been doing well if you go online to your favorite search engine like google or youtube and just search ryzen 7 5800x running too hot you'll find countless posts on various tech forums and many videos from users running into this problem in my 5800x review i also found this to be the case where at stock my ryzen 7 5800x was actually running hotter than my 12 core 5900x and when it came to power consumption it was in the same ballpark whereas compared to the previous generation 8 core cpu there was a significant difference this didn't make a whole lot of sense to me at first because why is an 8 core cpu running hotter than a 12 core cpu and consuming about the same power there could be two reasons here one is due to the bending of the chips as you know ryzen 5000 uses a chiplet design where you have an i o die and a core chiplet die or ccd that has physical cores within them i assume that the good quality 8 core ccds go to the 5950x for better boost figures and efficiency and most of the 5800 x's are just bad quality dies when it comes to efficiency therefore requiring more power as a result i feel like there are many 5800 cpus out there that just end up getting more power shoved into them than what's actually needed resulting in this bizarre behavior of the chip just running very hot and consuming a lot of power amd have actually responded to users noticing this behavior and they claim it's perfectly normal and by design according to robert halluck amd's director of technical marketing amd views temps up to 90 degrees celsius for the 5800x 5900x 5950x and 95 degrees celsius for the 5600x as typical and by design for full load conditions having a higher maximum temperature supported by the silicon and firmware allows the cpu to pursue higher and longer boost performance before the algorithm pulls back for thermal reasons is it the same for zen 2 or our competitors no but that doesn't mean something is wrong these parts are running exactly as designed producing the performance results we intended so if you have a 5800x or 5900x don't be alarmed if you see high temps under load than what you're used to you're not going to be damaging the chip with that said though if someone is looking at lowering power to reduce noise and heat they should be able to do just that in my last video we talked about overclocking the ryzen 7 using precision boost overdrive 2 and curve optimizer so this video will be an extension of that video however we'll be going the opposite way and i'll be showing you guys how i lowered my 5800x's temps and power consumption without sacrificing any gaming performance and you can easily do it too when i had overclocked the ryzen 7 5800x i found that despite raising the power limits setting a boost override of plus 200 megahertz and using curve optimizer and raising thermal limits this didn't really impact performance in games a whole lot i mean sure there was an increase on average but it wasn't anything noticeable which made it seem rather pointless i also found this to be the case for many rtx 30 series gpus i've tested where overclocking didn't really result in a huge difference when it came to gaming performance however i did find that undervaulting those gpus was the way to go because we could get near stock levels of performance while drastically reducing power consumption which results in less heat and noise now i didn't undervolt my 5800x or use any negative offsets instead what i did was that i went into my motherboard's bios and altered the pbo limits while pbl is generally used for overclocking you can also use it to reduce power and heat for your chip this is because at stock a ryzen cpu with a tdp rating of 105 watts has a ppt of 142 watts 95 amps for the tdc and 140 amps for edc all i had to do was enable pbo in my bios leave everything to default auto and use manual pbl limits when you're doing this you'll want to test various values and see what works best for your chip as every chip is different after doing various benchmark runs i found that setting a ppt of 115 watts 90 amps for tdc and 105 amps for edc worked the best and allowed me to reduce power while also keeping the same level of gaming performance i had at stock before we get into the benchmarks and results let's do a quick rundown of the test system specs so cooling my ryzen 7 5800x we've got the arctic liquid freezer 2 360 with the pump and fan set to 100 for our motherboard we've got an msi x570 unifi for the ram we've got four eight gigabyte sticks totaling up to 32 gigabytes of patriot viper steel ddr4 3600 cl 14 memory the gpu is an asus rog strix rtx 3090 which is the running stock for our storage we've got a two terabyte samsung 970 evo plus and powering all the components is an evga 1000 g3 power supply for our gaming benchmarks we'll take a look at just a couple of titles i did test more games but the results pretty much tell you the same story and going through all of them would be boring and a waste of time in shadow of the tomb raider when power limited the 5800x was just a tad bit faster when compared to stock for the average frame rate while we did see a minor loss for our one percent lows cyberpunk 2077 sees a 2 fps loss to our average frame rate while the opposite is true for the one percent lows these are pretty much margin of error figures nothing noticeable at all now i didn't show cinebench r23 results in my last video but i'll show them here in this benchmark it may seem like there are some considerable differences between the three configurations but as you guys saw from those gaming benchmarks those differences don't always translate to real world performance differences moving on to thermals and this is where we start to truly see the benefits of lowering power limits on the 5800x during our shadow of the tomb raider gameplay session which by the way is a pretty hit thread-heavy game we see a reduction of 5 degrees celsius when compared to stock instead of bench r23 we saw an even larger difference of 12 degrees celsius the temps that were observed when running the cpu at stock or even when overclocked aren't necessarily bad keep in mind i am using a pretty high-end cpu cooler here the arctic liquid freezer 2 360 which is one of the best on the market but there will be a lot of users out there who won't be able to use such a high-end cooler like this with their chip maybe due to costs or they simply can't fit it in their case in those cases where the user is more thermally constrained they'll definitely see some high temps and this is where limiting the power limits can come in handy along with thermals you do also get the benefit of lowering power consumption when it comes to power things get a bit interesting here in shadow of the tomb raider we see similar power consumption when looking at stock and power limited configurations yet we saw lower attempts the reason why this happened is because even though our power consumption was the same our edc was considerably lower on average we saw edc at 90 amps when power limited whereas at stock it was around 114 edc can have a pretty major impact on temps and we can actually see the result of that here instead of bench r23 which would provide insight on a heavy productivity workload like rendering where all the cpu cores are used we see a significant reduction in power when compared to stock what's also interesting to note is our power consumption when using pb02 overclock isn't that much higher than stock even though our limits were much higher therefore it makes me want to believe that these chips are just running with so much more power than necessary so after seeing these results i must say i am quite intrigued by how you can tune these ryzen cpus if you're running into issues with thermals you want to lower power and keep performance the same as stock well with the ability to tweak precision boost overdrive limits you can easily do that and if you want to go lower than what you saw here if you want to completely lower down your temps then you can go even further with your pbo limits there's a lot of flexibility here i saw many people online complaining about how their 5800x just runs warm if you're in that group i definitely recommend altering your power limits to keep that ship in check it doesn't take a lot of time to do and the fact that you can still maintain the same gaming performance is a win-win in my books if you guys
