WARNING 7900X and 7950X DO NOT use Ryzen Master Eco Mode

AMD's Ryzen Master eco mode will have a dramatic multi threaded performance loss on the 7900X and 7950X Processors! Testing included in the video.

the 105w mode actually looks great for the 7950x getting 35k score when compared to a 5950x which can achieve a whopping "27k cbr23 score" at 160watts

Just being able to select what wattage you want would be a lot better rather than just a single selection in software, BIOS is great, but it might be a bit intimidating for less experienced users

Thanks for this Tom, I did try Eco mode in Ryzen master and it caused all sorts of problems and ended up having to clear the CMOS, followed your guide and it works like a charm!

[DenTilloZie]

Tbh pretty impressive CPUs, my 5950x on PBO 180ish watt does the same in R23 with the 7950x on 65watt

Use the Curve editor to negative 10 - 20 all Core ( depending on the CPU Lottery ) and undervolt your CPU, if you want to cool by Air, then start with a 140/150 Watt Power Limit ( which is the AM4 PPT of 142 W ), you may loose 5-6 % Multicore Performance but you save 70-80 Watts ( under full load ) or if you set a 125 W Powerlimit you save a whopping 100 Watts at only 11 % Performance loss o n l y under full load . Its the full load where older AM4 Cooler can struggle to cool down an unlimited Zen4 with 230 Watts .

105W ECO mode is the sweet spot. You only lose 5-10% of performance, but reduce power consumption by nearly HALF.
On top of this, gaming and single threaded performance remain unaffected.

[CatheteriZedEYE]

they should test it more and then possibly just call it "gaming mode"
market it for IDEAL gaming with LOW power
genius

Thank you for covering this. Hopefully they will add more options in Ryzen Master for various TDP modes kinda like what these new handhelds are doing. As someone looking to do a SFF build with the 7900X it would be nice to be able to easily in software configure the TDP for max performance at a wattage that will support more cooling options

[Darkstriker]

I hope this means future Ryzen Master updates will be able to set ECO mode to correct power level per chip?
Whole thing would be better if it was smart enough to run eco all the time and just auto boost itself when cpu maxes out.

Eco Mode is great if you don't have a liquid cooler available to get chill the Ryzen 9 processor until you get one, that is my case.

[AldyNoor]

My proci ryzen 5 7600, and msi b650 a pro, im instal ryzen master why no "eco mode" y have solution?

[JamesAColemanFan]

Good stuff Tom thanks for the quick turn around and putting together a few graphs for us ! Hopefully amd pull the finger out and fix this :)

[ChrisRussellTech]

If you’re like me who started with a mid tower when I bought my 7900X, I then put the build in a FormD T1. The cooler options are limited and it does fit A 240mm cooler it’s very few that can fit that case with a 3-slot GPU. Looking at the L9a or AXP-90 makes sense.

[PeterBachmayer-ProDrummer]

The actual Ryzen-Master has one button in the "advanced settings", where you can chose 105W and 65W for eco-mode. This one works realy great right now - maybe AMD did some updates to Ryzen-Master in the last 2 years. So actualy you can use this tool to easily change the voltage by clicking some buttons without going into your bios - a great thing when you're working and maybe need a ton of power or if you just wanna reduce the voltage after some heavy multi-threaded stuff.

I guess Ryzen Master Eco-Mode will be getting patched for 170W multi-die processors vs 105w single-die processors, it sounds crazy they didn't account for this scenario 😅

[DavidFregoli]

For Multi-Threaded work, what matters is the energy used to complete a task, if we want to do things scientifically we should measure that.
What's the point of consuming 33% less if my render takes 50% longer?? In the end might use the same amount of energy.

[Thesinistereyes]

PBO2 with a negative offset can easily fix all the performance/temp issues.
Without hardly sacrificing anything.

[SpackenPro]

My Ryzen 7900x got only about 150FPS in Warzone 2 with Ultra Settings and an WQDH Monitor.
In the Eco Mode i got now between 220 to 260FPS.
So the Eco Mode dir the 7900x is realy good.

[Tritonix]

Just took a 7950x, a x670e tuf and 6000 mhz rams cl 32, hope is a good combo and enjoy that 105w from your guide <3

These are the settings recommended by AMD to anandtech :

170W TDP Base = 105W with ECO Mode enabled
105W TDP Base = 65W with ECO Mode enabled

170 W = 230, 000 PPT, 160, 000 TDC, and 225, 000 EDC
105 W = 142, 000 PPT, 110, 000 TDC, and 170, 000 EDC
65 W = 88, 000 PPT, 75, 000 TDC, and 150, 000 EDC
