9800x3d undervolted

[KrzysiuM]

I untervolted i to 1.03V and lowered the clock to 5Ghz from 5,2. Results are pretty nice temperature deacresed to below 50 celsius in most games, but will there be a significant loss of performance with that setting?

Little. Benchmark it.

it's not worth losing clock speed and perfomance, just use the curve optimiser and set it to -20 negative, at least mine is stable there, besides i got mine running on 5.6ghz

your doing this wrong.....unlike the 7800X3D the 9800X3D has the 3d cache in a sideways stack on the bottom of the CPU.....you have miles of thermal head room VS the 7800X3D that used a vertical stack on the die side of the PCB.....5.4ghz is the normal for the 9800 to run.....1.28volts is all that is needed in most cases......these CPU's always being at 70C wont hurt anything

as for performance its really going to come back to resolution used.....1080p will see loses 1440p not so much.....plus added in to this will be the game engine.....something like counter strike could see swings of a 100 frames depending on factors BUT wont really matter much when its something nuts like 400 frames VS 500.....

Ok i ll try tu push it on 5,4

when undervolting, dont mess with clocks as that reduces its power needed too

one at a time til unstable and go back to stable

Leave the clocks alone. If anything disable the Turbo crap and set the Base to the spec'd Turbo if possible and stable. However unlike old CPUs Vcore is not the only thing you need to worry about there are other voltages and offsets to change too.

With modern Motherboard and using WinOS you're probably better off making the changes with AMD Ryzen Master instead of the BIOS. Depending on what all you wish yo change.

Downclocking the CPU is rather dumb though. If anything, these CPUs can boost even higher while still staying under 75-85*C quite easily with proper cooling. But yes the voltages are good place to start since that contributes most to the CPU and VRM heat.

Make sure to lock in the RAM with AMP/XMP or whatever they call it now..

Make sure to update to latest bios from Motherboard maker and get latest amd chipset driver from amd website

do you have the same processor?

yes

In passing I noticed a video about this on youtube.

[nintendork07]

just to chime in with my experience regarding the 9800x3d.

in a normal size case, leaving everything stock works perfectly fine with a phantom spirit 120 dual tower cooler.

i haven't seen much improvement with temperatures going to a -20 curve optimizer setting, but since it's stable it will save a little power, so i just left it on.

you can go +200mhz on the PBO options and it stays stable with the -20 undervolt. just depends if you want to push the processor like that or not. i personally just stuck with a normal undervolt and no clock speed increase

What are your temps?

[Çapgun]

I cant understand why your cpu temps are high. Our amd normally 35 45 degree but under stres ocasionally 63 degree but not always.
Try disabling otomatic overclock nonsense your cpu and open cpu temp control. It will direct
