Can I tell you how to make your computer run faster than it should?
so my computer has a r5 3500, which is about 3.6ghz normally and goes up to 4.1ghz when it heats up more. It also runs at 4.0ghz if you let the whole chip get hot (allcore). The processor uses a lot of electricity for these boosts, but i'm not sure what that means. I have two versions of my ram: 2x8gb sticks of g.skill sniper x running at 3600mhz, which is fast memory. Now im trying to make the speed go up a little bit in the BIOS menu from normal, so it can handle more work. i set it to boost allcore to 4.5ghz with less power (1.3v) and that keeps my cpu stable at about 2900 multipliers when i do some manual tweaks. This helps my single-core speed go up too because the ram is running faster, making the single core score higher like 510 points on a test.
i am trying to figure out how to make the voltage change depending on how much the cpu uses it. right now the power stays at 1.3v even when the processor is doing very little work or going full speed. i want something where low usage needs less voltage like maybe 0.5-0.7 volts, but high load needs more voltage up to the limit of 1.3v.
i know some things about ryzen overclocking before but can i do this with my current setup? for example when my cpu uses a little power it should use lower voltage and when it uses all its power it should use higher voltage, like if i run at low load I might only need 0.5 volts but when i run the full speed test or heavy tasks i want to hit the max limit of 1.3 volts.
my old build used a i5 4670k which also ran at high speed and used about 1.25v even though it stayed at that same power level all the time. in my new ryzen setup, if i keep the multiplier the same (like x45 or whatever number is there), can i still get a lower voltage for light tasks but a higher voltage for heavy tasks?
Best way to do it: don't try it yourself. The computer does the work better than you can. What works for Intel chips doesn't work here. Put in a really good cooler, stick two sticks together, set speed to 3600mhz with low timing, and call it quits.
Best way: just stop trying to do it yourself. The computer chip handles the work better than you can ever hope to fix things manually. What works on normal CPUs simply won't work well here. Make sure you have a really good cooling fan, connect two powerful graphics cards together (dual channel), set them all to run at 3600 MHz with a low latency of about 16 or 17 microseconds, and then call it a day.
so just turn on the PBO from inside BIOS and let your CPU think it's working? what specific settings do you need for PBO? I am trying to reduce C19 down to C16, but my chip is a B-Die (Thai phone burner read) and I have a great cooler called H110i GT.
I laugh when I read that little manual overclocking guide followed by 4.5GHz on all cores for a CPU designed only for 4.1GHz on one core. That might seem small to you, but it isn't really small to me. As Phazee88 usually writes, you should leave the CPU alone. I don't know what you did to call this "stable," since running Prime95 small FFTs for about 20 to 30 minutes is not a great way to tell if something is stable. B450 motherboards are often not good platforms for fine tuning (especially lower and mid-range models), even maybe it's impossible on high-end ones like X470 or X570. I would really leave the CPU alone, but if you insist on keeping the overclock speed at your own risk, after all overclocking voids the warranty, then use a good cooler (as Phaaze88 wrote), lower the OC slightly to 4.4GHz and try to keep the voltage close to 1.25 volts or even lower if possible. Oh, and also keep an eye on the temperatures. Usually hwinfo64 (sensors only option) is one of the best monitoring apps to see everything in one place (and also keep track of the Max, Min, and Avg values).
hahahaha 😊 +0.4Ghz it is a big gain... so how should i set the PBO setting or just leave everything on auto for my cpu cores? ofcourse I'll set the memory to 3600 C16/17, but I'm just figuring out what else I can do with a 3500. Probably not gonna daily oc it because my gaming experience hasn't gotten better since my 4670k at 4.5Ghz, but at least the cpu isn't using 100% power anymore and that's actually good, right? I'm using HWinfo64 to check all things, never reaching 65C while CB R20 (29C ambient).
