I rarely post but there are some misconceptions in this video (not blaming Tech, you're doing what you can and the content is relevant and entertaining!). I have binned 5+ 7800X3D and while it seems initially that all of them can do -20 all core CO, they rarely pass real stress tests. Only 1 out of 7 can do -30 throughout the cores, and in some instances, some individual cores barely can do -5. PLEASE TEST YOUR CPUS PROPERLY. Having said that, I dont think CO is too relevant for 7000s, especially how YES also noted, you dont necessarily save on temp, it just boosts higher/longer. Therefore I suggest getting a very good cooler coupled with CO and dont worry if your CPU doesnt CO too much. ANOTHER thing Ive noticed is that some CPUs are just binned higher (better VID), where they run at 4890MHz out of the box (CB23) while others barely break 4850MHz with -20 CO. Finally, there is no correllation between CO and Max FCLK or MAX Bootable RAM Frequency. I much rather have a CPU that can do 6600MHz 1:1 at 2200MHz than one that can do -40 CO All Core. My best 7800X3D can do avg -25 CO (some cores -35, others -10), does 6400MHz 1:1 C28, FCLK 2133MHz with 100MHz or -5 CO All Core @ 105MHz (eCLK). EDIT: Also read about CLOCK STRETCHING.

yeah, curve optimizer stability is much harder than intel offset or lite load undervolt to test in my experience. I also cant seem to get Core Cycler to ever error on me with zen5, might be missing something. It did work for zen4 and actual curves were in the range of 5 to 30 on most CPUs... pretty wild actually and that -5 core would cause maybe 1 crash every other month.
@ferdi6346Ай бұрын
I totally agree, thats what we call Sillicon lottery. For me personally every core has different values that i found out by running Prime95 with every new offset for atleast 2hrs, once a core crashed i just set it to the next stage. Startingpoint was -40 ended somewhere between -21 to -29 for different cores. Did the same for my friend he had complete different results. One core could manage to run -38 while core 2 always crashed over -10. Ofc after running prime95 successful you should also try other things to somehow stress the cpu.
@123TheCloopАй бұрын
yeah I pointed this out in his 5700X3D and in this video. you rarely stress test CO results. as most of the cores primarirly crash at idle states and he also ignored the most glaring issue that in lot of cases can net you less performance and thats clock stretching. so while maybe -30 looks stable and doesnt crash, it doesnt also mean its the best result as you could be clock stretching to a point your losing performance. overall its a bad video imo, 2 crucial pieces of information were just left out, which is using Corecycler or ycruncher to test cores individually over several days of continious testing and clock stretching NEEDS to be observed when setting CO offsets

Long time overclocker with experience. Cinebench stable with these chips using curve optimiser is easy. However, they can seem stable but will crash infrequently if there is no load at all or dropping from high to low load. You can test with CoreCycler, but it's much more time consuming than with Zen 3 non X3D. TL;DR plenty of these are cinebench stable at -40 but will crash under no load until you dial them back to around -30.

thank you, CO results NEED to be tested in idle conditions because ryzen cores down volt which is why they can crash when you offset (drop the voltage curve) so in idle situations the core literally isnt getting enough power (think it like a GPU crashing when down volting) its a little complex than that but im annoyed he thinks just -30 and cinebench are "how you test curve optimizer"

I think its very important to always double check if the undervolting worked by using cinebench. Because undervolting slightly too much wont make you immediately blue screen, but you get so called Clock Stretching, meaning it looks/"acts" like you get the desired clock speeds, but in an absolute test (like cinebench) you get a lower score.

I've also set some curve shaper values, but since I ain't got what the feature works really I test them out currently. So far I have to say my 7800X3D is running with -40 Curve Optimizer undervoltage and clocks ingame like cyberpunk majority of the time with 5050 Mhz, and pulls around 60-65 watts.

This could be a game changer as crashes often occur when voltages over/under-shoot with big changes in load.

@@ConnorH2111 doesnt matter what your using, -30 offset is not stable if your getting WHEA errors, (these are core crashing errors) should be Event ID 19 if its a core crash.

But please, dont use OCCT/cinebench or pimre95 to "test offset values" download corecycler (which does use prime95 ironically) but its on a per core basis and does random work loads at varying usage levels per core. you need to run this for a good 3+ days when testing offset values and see if any cores are flagged as "crashing" or failing in the program. Then you need to use something like cinebench to watch for what is known as "clock stretching" which is basically the difference between your effective clocks and "core clocks" value in HWInfo, any difference greater than 15mhz means your CPU is reporting an incorrect clock speed mometarirly due to not enough voltage to the core/thread so as a result misreports the clock by throttling down to match the given voltage supplied. (again something he grossly doesnt mention) So while that -30 could be stable even after corecycler testing, it might actually be yielding worse performance than lets say a -25 offset due to clock stretching

It's pretty toasty here now (28-30 ambient) and I was seeing 90C peaks. Now its more down to 70ish.

Whatever I do, I can't make my CPU stay at 5050MHz All Core in game. I tried all core or per core PBOs. I use x670e tomahawk.

Pro tip, don t OC the 7800X3D, especially PBO, it causes instant stuttering, for example in CS2 it s terrible. It s a very good chip at stock settings, less headaches!
@Silent-198314 күн бұрын
I set all cores to -30 with an PBO on 80 Celsius limit, and my temperature was the same in Battlefield 2042; I just don't understand the point of undevolt for the 7000 series! I have a 7800X3D, and I don't notice any changes in games; the CPU is running great, and the only heavy CPU game I observe is 70 degrees Celsius, the rest are 59-65 degrees Celsius!

I had to increase CPU related settings in DIGI+VRM section of the BIOS to 120% to get a stable -30, without it it was stable at only -16
@starlightHTАй бұрын
It's not true, we can do Oc at 7800x3d even without access to the multiplier. The old way is to gain 150 to 200mhz easily, move the memory back, FCLK and increase the bus speed... Technically it's not worth the time.

Curve optimizer is really frustrating to work with because when I run every benchmark for stability, things work out great, but after two or three weeks, my PC crashes just while idling.

@123TheCloopАй бұрын
no he really doesnt, if you value a proper stable CO offset, go in intervals of -5 all core and keep testing using corecycler and watch for core crashing (and observe for clock stretching)
@B3tterEv3ryDayАй бұрын
True and i swear i watched like 6-7 on this, every one of them barely did any stress testing and called it stable at -30 offset. My ryzen 5900x which some said undervolts really well, if you stress test with cinebwch or other all core workloads it works at -30, but its stable only with -10 offset.And i properly stress tested each core individually for about 2-3h each.

@chameleoneelАй бұрын
Maxing out the LLC will make the CPU run hotter. You will get a lower Curve Optimizer number, but your CPU will run hotter. And that's because High LLC actually overcompensates on voltage. My 7800X3D can do -39 with the LLC maxed, but runs ~8 degrees warmer in Cinibench, than - 20 with the regular LLC setting.

Validate Offset is not enough to find stability. I had to come in here and chime up. Been using offset for a while since back when it was capped at 30. I know my chip can only do around 20 all cores, but ryzen master validated at -40. This boots but is an almost instant crash in Cinebench R23.

7800x3d (Curve Opt. is at -39, -40 was too low) with D15 Cooler, ambient temp. 26-27 Celsius, x670P-Wifi MB, 6000MHz DDR5 CL30, Taichi 7900XTX and I'm averaging 18200-18500 points in Cinebench (10 minutes), CPU temp was around 85-88 Celsius, Throttling is set to 92. 😅 Should I fine tune it more, or is it good? It's stable while I play, or stream as well (CPU Encoding x264 with OBS, 3440x1440, but stream is FHD). Edit: Changed to -30 and Throttle temp to 80, avg. 17300 points in Cinebench. Goes back to -39 and 92. Still looking for advices. Thank you!

Bought an AIO, tested the cores with Prime95. SoC 1.150V, Curve Optimizer: 1-5 Core -39, Core 6: -35, Core 7: -38, Core 8: -37. Prime95 Test duration (Blend all of the above): 6 Hours, 500 Tests, 0 errors. Cinebench: 18531 pts @4.85Ghz with peak temp. 78 Celsius. I can maybe fine tune it more, but wanted to test it with games + streaming. 65% CPU usage (x264 encoding), 60 Celsius, and because of the AIO, I have better airflow in the Case, this means that my GPU temps are also lower on 100% usage, it sits now at 65 Celsius (80 Celsius Hot-Spot).

Do I need to install both PPM file & 3D V-Cache Performance Optimizer when installing drivers for 7800x3d? I've read that those drivers are only for the other 3D models with more than one CCD but the drivers still show up with the pack I got from AMD

For 7800x3d just downloading the chipset drivers and updating the bios is fine. 7950x3d can be a bit of a headache but I generally don't recommend that cpu.

We need a better and faster way to quickly tell us the highest curve optimizer setting per core. It takes a fair amount of time, at least a few hours, to do it all manually to maximize per core settings.

@jjlw2378Ай бұрын
What brand motherboard do you have? You'll need to either increase or decrease your Load Line Calibration (LLC) to give your CPU more voltage under load. This could stabilize your CPU under lighter loads (gaming, KZbin, idle), while still providing plenty of voltage in heavy loads (R23, Prime95, OCCT). Experiment and see if that helps. Good luck!
@123TheCloopАй бұрын
because prime95 and cinebench are NOT what you use to test stability for curve optimiser results.......... his video is illinformed (again) use ycruncher (pref corecycler) and test idle stability of each CO value and I can bet you get failing cores on 1 or a few values which is probs why it "looks" stable under load but doesnt in games as most games will not always slam the CPU to 100%
