Check out how I built this Beast in the HYTE Y70: kzbin.info/www/bejne/r57QqYFnaZaWrqs We go over How to Undervolt an AMD CPU to Get More Performance and less Heat. The Ryzen 9 7950 is a monster, I show you how to tame the beast and get more of what you want, be careful. Important Note: While optimizing your AMD Ryzen 9 7950X can significantly improve performance and reduce costs, it’s crucial to proceed with caution. Incorrect configurations can potentially harm you and your system. Please ensure you understand each step and how it applies to your specific setup. If you’re unsure, check with me to help you. Disclaimer: I cannot be held liable for any damage or issues that may arise from following these instructions. Proceed at your own risk, this worked for me, it may not work for you. Edit: I had more stability issues on day 3, so I bumped up the voltage to 1.13 and it's stable now.

I have found that R24 tends to be better for testing stability. When I was fine tuning mine R24 I ran them both and it would crash on R24 long before there were any issues in R23. If you are going to invest the time to do some serious fine tuning you can either pay more for a motherboard with a clear cmos button (a lot more and not worth it just for that IMHO) or get some jumper wires and a switch for just a few bucks to make resetting it much easier. Then once you have everything dialed in, you can simply take off the jumpers.

@ThisBytesForYou 4 ай бұрын

Hahah which is why I had it installed, I found r23 to build more heat than r24, give it a try. I was trying to build more heat, good idea right when trying to build heat? Agreed, I should have paid more for one with a clear cmos button, and in the rush to make the video I didn't want to spend too much time looking for a jumper, I know I have one but hind sight and all and yes I was going to buy a longer one, would help in future builds, just never needed one in the eons doing this,, I got spoiled with boards that had the button. It really is a great board but this is the only flaw I have found.

@gscurd75 4 ай бұрын

@@ThisBytesForYou Very true. When I get a new CPU I generally run both. R23 to get more of a heat load and its a much faster test. That lets me know right away if there are any issues with thermals. Then I run the R24 which takes a bit longer to make sure it stable.

how come when i choose manual mode my cpu clock stays at 5.3 even when un-stressed? when im in default it goes down to 4.10 in idle and ramps up when being stressed

@ThisBytesForYou 25 күн бұрын

When you set it to manual you are telling the cpu what it should be at, rather than auto being what it can reach on its own and what it can slow down to when not in use. This also has to do with your chipset driver and power plan. If you would like to understand those, please let me know the manufacturer and model number of your motherboard and cpu.

I have a ASUS X670E Crossfire Hero motherboard with a Ryzen 9 7950X CPU. I've seen some people advise against using Ryzen Master for this kind of tweaking and to instead do it within the BIOS instead. Do you have any tutorials on how to achieve the same results via the BIOS?

I don't, Ryzen master is working perfectly I may make one but those people that advise against it, you may want to ask them for their settings.. Ryzen master works great.

I'm using an air cooler deepcool ak620 digital pro and the least i can get it to undervolt is at 4800 clock speeds and 1.06 volts. lower volt than that, it just restarts my pc when i press apply and test. Can you givew me some insight on why I can't copy your settings? Is it because I'm using an air cooler?

@ThisBytesForYou Ай бұрын

As I mention in the video, even though the CPU is the same, its not really the same, 2 identical CPU's can have different voltages and more, the board has a lot to do with it, are you on the latest BIOS version? Try at 1.06 and see what your temps are like I show you in this video

@@ThisBytesForYou okay I understand. I am on the latest bios version. I'm using gigabyte b650m aorus elite ax ice. the temperature at 1.06v with 4800mhz is around 65-70 under load. I bump up to 5000mhz and the lowest i can get is 1.125v with the temperature max load at 89 celsius. It usually spikes after the stress test in ryzen master ends. I haven't stress test it in cinebench because it is so nerve wrecking everytime i press the apply and test button XD Another question I have is why does i set it at 5000mhz but in hwinfo it shows the core clocks at 4991mhz?

OK, if this is your RAM, are you running in AMD Expo or XMP? this particular kit supports both, but if you have been running on Expo, try XMP or vise versa, since the CPU has the memory controller on dye it could make a big difference: www.klevv.com/ken/products_details/memory/Klevv_CrasVRGB

@ThisBytesForYou 4 ай бұрын

Yes the 7950xt gets much hotter than the 7800x3d with any cooler. the chip is designed to run at 95 degrees and normally gets to 95, that's why undervolting is a thing. It kind of bled over into other chips and inadequate cooling and bad ambient temperature situations so it has many uses, looks like you are good though. This processor is a monster and I've never had any issues in any other CPU
