You can manually adjust settings if you wish after but let it do it's thing and set the values in your Bios. All cores negative 30) and then you set again the “general switch” of the PBO to AUTO or even DISABLED you might think that the curve optimizer settings are disabled too. 1, boost clocks 4. Initially, without Ryzen Master enabled, the only two options were disabled and enabled. . 2v. I read the guide from katalysis (Guide: Zen 3 Overclocking using Curve Optimizer (PBO 2. Wondering if anyone has experience with using PBO and curve optimizer with the 7800x3d. 2njust for precaution and saw many posts about the PBO and curve optimizer so I set it to -20. Tried everything and I couldn't find a decent fan curve that would be pleasant to my ears: an aggressive curve was way too much noise with the case next to me on the desk. -30 all cores, 125 PPT, 80 TDC, 115 EDC We would like to show you a description here but the site won’t allow us. my ram is a bit better, 6200mhz, 380 trfc, 36 on secondaries, 20 tfaw, 66032 97205 65739 read/write/copy, 58. All these changes combined cinebench went from sounding like a jet engine was going in my pc with 90c core temps, to almost inaudible at full load at 75Cish temps with negligible or maybe Went in -5 steps on the curve optimizer, ran the included Ryzen Master "stress test" for stability, then ran a Cinebench with all apps I could stop stopped in windows for ideal replicability of results ( cinebench results can fluctuate quite a bit even doing this ), anti virus off and everything I could think of. I got some nice results with a -30 allcore CO. Set the curve optimizer sign to "Negative" Enter "25" for the "All Cores" offset number. 30-40 C while idle, 60-65 C while benchmarking and about 50-65 C while gaming. Once you select the curve optimizer settings (i. Boost clock offset nothing happens. Go into BIOS / Advanced CPU settings / Precision Boost Overdrive / Curve Optimizer. Tested this a couple of times and it’s accurate at least for my board. Only after enabling curve optimizer in Ryzen Master I get to see the “advanced” PBO settings in the ASRock bios. Find best curve values using occt avx2 extreme. Find lowest. I tried all of this, made it through a few stress tests to my satisfaction and then crashed while watching YouTube. It is Curve optimizer lets you use negative values to reduce the voltage used by the processor which lets it run cooler, more efficiently, and potentially opens up more headroom. Kinda like curve optimizer but it shifts the whole thing including the max frequency. For curve optimizer, no. After disablimg curve optimizer everything is stable. Case: Pure Base 500 FX. 3 degrees max. I have a 5900x but what works very well for me is using Ryzen Master as it lets you do the tweaking on the fly. 10. Basically curious how high the negatives can go on the best cores. All the configuration here has been tested, over 168 hours on OCCT Prime95 and AIDA64 Core 0 = -40 (Rank 5 Core) Core 1*= -40 (Rank 1 Core) Core 2= -31 ( Rank 4 Core) Core 3**= -31(Rank 2 Core) Core 4 = -24 ( Rank 7 Core) Core 5 = -30 (Rank 3 Core) Core 6 = -31 (Rank 8 Core) Core 7 = -31 Latest version missing auto-detect Curve Optimizer feature for 7800X3D (Start Optimizing button replaced by Validate Offset) Reverted to version 2. Left it like this: Then go to "Curve Optimizer" to see be below screen: This is where the amount of undervolt is set. Planning to try again at a lesser offset. SOC will probably work at 1. Decided tested curve like these 0-0-0-0-0-0-0-28 etc every core but cpu sha3 not getting bsod, then i decided increase curve by 1 in last core (7) and test cpu sha3 and overall i passed 100 times cpu sha3 without bsod with value on last core -13. I'm going to be upgrading from an OC'd 8700k to this and wasn't familiar with what sort of possibilities there were with getting more performance out of the CPU. I don't understand how this curve works on CCD0 with cache. Pbo curve settings in the negative reduce the power draw that each core can receive when they demand power. In my case that is "39". 7900x3d btw. Going by what I saw online I put a all core -25 curve optimizer on in bios and it definitely works good because in cinabench multi Core I'm getting high 18000s but I noticed that even while idol now every Core is constantly boosting to 5050mhz and I just want to make sure that's supposed to happen and that it's Go into BIOS / Advanced CPU settings / Precision Boost Overdrive / Curve Optimizer. Hey, thought I'd follow up. I spent hours messing with these settings and always get 18500-18600 in cinebench. Also for the most stable Curve optimizer vaIues I would strongly recommend using Ryzen Master's curve optimizer scan per core. I was able to lower the temp using Curve Optimizer with the old one but with the new one, the temp doesn't drop at all. You can't really turn on CO without turning on PBO2. Would say this is totally fine May 9, 2024 · Also, I recommend tuning the SOC voltage with PBO curve optimizer off as instability from that could be misconstrubed as RAM instabiltiy. Max power consumption 62,52 watt. Well not really. I believe the two tend to be tied together though. I bought a 7800x3d, and so far I really enjoy it. This was from some testing with Curve Optimizer offsets, this was running the fast cores at -37, and the rest at -45. That's so weird dude. Ryzen Master provided the following values which were ridiculously low (-45 to -49). 919mhz max boost. Curve optimizer, the other is for the internal gpu on the cpu I suppose, never touched it. It will take a while to go, but you'll end up with values in the CO All Core Value and Difference Offset Value. You want to set the "All core curve optimizer sign" to "negative" (we're going to reduce voltage" and "All core curve optimizer magnitude" to the number of millivolts to adjust the curve. Since using Buildzoid's settings, I've been able to push the Curve Optimizer offsets much further (everything was previously about 5-10 points lower) with less instability. PBO, then go to Curve Optimizer (or C. I would prefer to keep things stock clocks or better. The "simple" path is to undervolt all cores the same amount. -30 seems to be considered "winning" the silicon lottery but how far can it go? Performance Tuning/PBO (located either on Main page or AMD Overclocking): "PBO w/TJMAX of 85c Curve Optimizer -20mv". 7800X3d and curve optimizer issue Hello, I come to you because I encounter a problem with the PBO and the curve optimizer on my 7800X3D, in fact as soon as I modify the curve optimizer to put it at -10 (low value) on all core, the system is unstable and cinebench 2024 crashes, windows is not stable either. e. Well mine is running with PBO2 and Curve Optimizer so I try to get out the maximum. com)) and was very confident that I had learned about the somewhat unusual test of forcing "Windows 10 Automatic Repair and Diagnosis" for ten times. Ppt of anywhere from 60-80W if there is too much noise/throttling. Set the curve optimizer sign to "Negative" Enter "20" for the "All Cores" offset number. Max out the LLC for your CPU Vcore. I got around 800 points mote in cinebench R23 going from stock to -36 avg CO so about 5%. I previously used DOCP I with no custom settings beyond that except maybe a tune down from 6200 MHz to 6000 MHz. PBO2 lifts the ceiling, and Curve Optimizer can be tuned to give you the thermal headroom to hit those higher frequencies. 0) : Amd (reddit. 7800x3D Curve Optimiser tips Just upgraded to a 7800x3d and I'm blown away by this cpu's efficiency and perf uplift from my 5800x. 2. 18605 was my highest. Wanted to add my findings in case it helps someone. Activate PBO. List your curve optimizer gold core negative offsets. You normally use both PBO2 and Curve Optimizer together. Auto since they aren't even close to being hit, I think there's like 50% headroom on most pbo limits with the x3d. My 7800X3D isn't any special too. We learnt this back when Curve Optimizer came out for Ryzen 5000. Cinebench -> 18306 pts. 2) Activate PBO. This means that the limited amount of voltage available to the 7800X3D is maximised and the voltage won't droop under load. As I remember, it works with a curve optimizer at -20. I recently bought a ryzen 7800x3d with a Gigabyte Gaming X AX mobo. Do you care about 1000 points in Cinebench at the cost of stability in games? Go curve optimizer -30 You're better off doing memory overclocking on the 7800X3D, and you're not going to get more than 5% in most cases from that either. It's called curve because the plot of the Mathematical function is a curve. I did some quick testing and found some interesting info I thought I would share. Je viens d'utiliser Ryzen Master pour activer PBO (aucun changement manuel) et l'optimiseur de courbe réglé sur -20 All Core. Trying to further optimize, I went with the per-core CO. my guess is due to small amounts of 7950x3d being sold these With the advanced boost curves these CPU's have, manual voltage adjustments are only really useful for static manual clocks. My idling temp right now sits at 44 - 45 degrees while typing this so that has gone down a bit PC components: 7800x3d, 7900xtx, 32gb ram corsair vengeance 6000mhz cl30, Gigabyte b650 aorus elite ax rev 1.

PPT limit lowering affects heavily multithreaded tasks. Trying to finish refining the curve optimizer on a 7800x3D I started messing around in curve optimizer because my 7800x3d doesn't seem to really be boosting single core at all above multi core, and by default was doing like 4. Smoother gaming performance too. Later on when you "get to know" your cores more, like, which one boosts higher. Curve optimizer can help get slightly higher clock speeds but for longer periods of time, and can help lower temps too. Decided to replace all the case fans with x6 Noctua NF-A12x25, which helped, and lowered the idle temperature by 5º and the noise became acceptable. Save and boot back into Windows. Memory Profile: XMP/EXPO Profile 1 Memory Performance/Tuning: Set from AGESA Default to Aggressive One thing you could test is to keep PBO2 on, but set negative Fmax offset. Upgraded to a 5800x3D, used Curve Optimizer in BIOS for the first time, performance improved tremendously with much lower temps, total win-win. Definitely runs cooler then before. **Do not breach past -20mv, 7800X3D does not like going past -20mv. I built my first pc couple of weeks ago and I limit vsoc to 1. I applied the setting "Kombo Strike 3" and compared with Cinebench R23 before and after, measurements were read with HWInfo. If you set it at 104, that would be 4% and new max would be 5250. Just performed some tests on my 7800x3d and i wanted to share some results from Cinebench. Since benchmark results are quite low wrt to the average results I see online, together with core clock, I tried some undervolt with Curve Optimizer. 0-1. There's enough guides on YT for this. O. I just got my 7800x3d installed yesterday. Under "Curve Optimizer" change the sign to "Negative" and then you should apply as high a number as is stable. Each step is around 3-5mV. Go to Advanced View, Curve Optimizer on the side, then set Curve Optimizer Control to All Cores and then click Start Optimizing. 3) Under "Curve Optimizer" change the sign to "Negative" and then you should apply as high a number as is stable. I dont really know the specifics to OC this thing, but I enabled PBO (just a single option to "enable"), and set curve optimizer to "pbo, 85c, -30). 4. Help (CPU) Hello good people of reddit. So, I took your advice and after running P95 small FFTs all night without any errors, I ran a 15-minute OCCT default test without errors, then proceeded to run 1x 1h large and 1x 1h small data set stress test in OCCT and lastly I ran a 8+ hour CoreCycler y-cruncher test, again, no errors. 5k cinebench multi, same single core as you 1850-1860. Manual Thermal limit nothing happens. Temp with PBO on advanced -> thermal throttle on 80 degrees -> curve optimizer on negative 20 -> 81. MB: Asrock X670E Steel Legend. With a -30 offset it'll do 4. 8 all core, but it'll be doing that at thermal throttling. very impressive, just wish it would persist after reboot because I'm gonna forget. The curve optimizer settings stay in place but the PBO limits get set back to default values. Cooler: Dark Rock Pro 4 - fan curve set to Standard. Troubleshooting: I've tried resetting everything to default but still same score. I set -25 negative curve for every core and +200Mhz positive boost and no difference. May 5, 2023 · 1) Max out the LLC for your CPU Vcore. You want to be eliminating as many other variables as possible so that when tuning SOC you know that it was your SOC value that was the cause and not something else. This way the CPU boosts lower (and hence uses lower voltages to do that). Couldn wow thanks, curve optimizer does well. ive been running -30 curve optimizer since the day i bought it (last 2 weeks ago) been playing warzone, left the pc on for 2 days because i was downloading games (on a 10mbs internet, its free intertnet in my apartment) seems to be stable, i never had a blue screen or random restart. The less power or undervolting component is Curve Optimizer. Try reset bios. 2367 and ran the auto-optimizer Many paperclip jump-starts later, I realized it was a waste of time. When you add those two values together, they give you your PBO offset. My 7500F died 2 weeks ago and they replaced it with a new one. I'm trying to set PBO + curve optimizer and coming from a 5900x and reading a lot of guides, it looks like best cores should not be able to have lower negative offset than the other ones. After I had been working with the Curve Optimizer for some time. In Windows, open Ryzen Master's "advanced" tab, look under the Curve Optimizer settings, and confirm that you see the "All Core -25" offset I'd recommend you to enable Performance Boost Overdrive in the BIOS and also enable the Curve Optimizer. I lost 10c not only in all core cinebench but also in cyberpunk and new world. I also believe it's disabled for x3d CPU's. Set it to All Core, Optimizer Sign to Negative, and start with a value of 20 and see if you can get away with more via stress testing. May 24, 2023 · I wouldn't start right now with a per core curve optimizer, go with a all core soft curve optimizer, start with -5; -10 or -15 all core and check stability, voltages, performance and temperatures. 2? Will the motherboard support the 48gb ram at An interesting video showing an example of what can be possible overclocking the 7800x3D. Hi, When im running a -30 curve optimizer on my 7800X3D, i get Cinebench r32 scores in the 17K', and when i bump it up to something like -15 or stock, im in the low 18K's. This makes now old y = f(x-30). Will the a620i be enough to handle a 7800x3d? I know I'll lack some features such as curve optimizer and undervolting - I do not plan on OC'ing, but will I miss any of those features from a throttling perspective? Can I remove the heatsink on the motherboard instead of removing it from my WD m. But if you wanted to, you can play with curve optimizer in PBO settings. 5ns latency (which is sensitive to background apps, make sure everything is closed and don't even move Just started messing around with this stuff since I heard starfield is hard to run. It all looks pretty similar to me, except the the temps with a 2 degree difference at most. It did OK on this quick core cycler OCCT test, and havent had a singe random restartwhen doing light activity so probably gonna use those for a while. This means that the limited amount of voltage available to the 7800X3D is maximised, and the voltage won't droop under load. The pbo elements allow you to increase max frequency, and raise or lower headroom on other thermal and power elements. I also adjusted my voltage curve optimizer to around -20 across all cores and reduced the maximum allowed voltage drawn by the entire CPU by around 10 watts. How to test curve optimizer undervolt on 7800x3d? Help (CPU) How should i test the 7800x3d? i do not know how to setup prime 95 or corecycler,i just set a temperature limit to 80 and -30 pbo + amd expo on,i seem to be crashing pubg for example to desktop,3dmark timespy test and cinebench can run forever x670e tomahawk msi board Hi, in curve optimizer do I have to put a higher negative number in the best or worst cores? now I have all at -20 I have core 6 which goes maximum at 4,750mhz while the others exceed 5,050mhz with 102mhz eclk and curve optimizer -16 -15 -25 -22 -19 -20 -23 -31 i get 18. Only if it is under 100% load I can see the 89°C package temp but in most of the games it is between 50-60°C and in demanding games like battlefield it can reach the 70°C. I’ve went-30 nothing happens. Boosts nearly to the same values then stock with -15 on curve optimizer. You can however play with Curve Optimizer (CO), and set a negative offset for the cores. Hello PCMR! Yesterday, I did some testing with using the MSI feature "Kombo Strike" to optimize the curve of by 5800X3D CPU. Results: CO disabled: 17473 points, max. Been messing around with CO try to lowers the temps and gain some more efficiency but I'm finding the cores vary drastically what they can handle without throwing WHEA errors etc. To other users who are just fine tuning with curve optimizer without the eco mode. Asrock b650e Taichi, 64gb gskill neo 6000/30 running stock expo timings. 8 GHZ. So I've been wondering what kind of returns curve optimizer gets with the 7800x3D, as the artificially low max clock speeds limit it a bit compared to the non-3D parts. I can confirm, curve optimizer set all core at -39 and after gaming sessions my pc just randomly restarts. In my case, that is "39". 6 on both single and multi-core. Point 2 might get you better all-core values. After bios reset i set -10 for negative curve and temps going down and boost is almost 200Mhz up 7800X3D Curve Optimizer . I am loosing like 1-5% performance max. Even if I do negative -30, power consumption always appears to be 65w It was dropping to 45w when i used CO on the old one. Also the curve optimizer has way more effect on temps of my 5800x3d than my 5800X ever did. The more well known feature is Curve Optimizer, which you can use to lower the voltage targets across the frequency-voltage curve. ), then select something like "all cores", and then select "negative" and set it to -20 at first. Get the Reddit app Scan this QR code to download the app now 7800x3d Curve Optimizer Clock Stretching . This allows the cores to run cooler with less power input, which ironically gives them more thermal headroom to boost higher with lower temps. The mathematical function f(x) = y where X is voltage and Y is clock gives a curve and if you apply CO - 30 it means you are moving the graph along the OX axis to the left. Many people would get stable under heavy loads in Prime95 etc, but then have crashing when left idle. temperature (c): 88. Here is my configuration in bios for the curve optimizer. meyxxyxd zkxeuq zdurz betuny xpbotj qbno zdceo lmoybm kobzw wqfwknu
