3800x silicon lottery. 4.4 ghz 1.256vcore.

[Izu79]

Good day everyone.
3800x
Asus tuf x570
Corsair vengeance rgb pro 3200mhz c16 b-die downbin. Running at 3200 16 17 17 17 35 1t. Ryzen calculator didn't work at all.
Sabrent 1tb m.2 .
Hyperx 240gb ssd x2
One 360 open loop rad would have been enough really. Each extra rad only dropped cpu temp about 2-3c.
Msi 2070 ventus.
Open loop. Dcc 3.25. Ek supremacy. Darkside rads. 360, 240, super thick 240. 15 120mm pressure fans. 3 140mm fans .
Everything in push pull. And case fans to blow extra air in.
Corsair 780t white.
Evga 850 gold.

So 4.4ghz prime stable avx and everything, cinebench, memtest ,games bfv metro at 1.256 in bios. Llc 4 to stop vdroop. Going to see if can run llc at 3 but so far lowest i can go.
So got the ultimate golden chip.
According to gamers nexus video of safe voltage. I technically could be 0.2 higher if measured on the board.
In which case my golden chip is just a regular ol 3800x.
So overclocking gurus and electronics specialists where do i measure vcore on the board. Not a 800 dollar board with actual spots for measurements. Where do i look?? Thx very much.

May I ask why you want to measure manually? Do you not trust the BIOS or CPU-Z results? Also, the "safe voltage" that is noted is merely a guideline. The numbers that people like PC Jesus post are suggestions from the manufacturer and personal experience and will generally favor the side of caution. From my experiences keeping the CPU cool is far more important for long term use that a generic guideline number.

With that said, for short runs so long as you are keeping the CPU cool (benchmarking, etc) it's ok to test an OC a little above these numbers. For 24/7 running though, I wouldn't recommend it.

are we saying that more than 1.256v is bad for the ryzen cpu's? My board if left to default bios settings will throw more than 1.4 to my 3700x

 

[Blaylock]

The way I read his post is he had another .2v meaning the safe limit is 1.456v which is right about where I would expect it.

Well normally i would trust the bios and cpuz, as i have for my overclocking the last 20yrs. I guess the problem is information. I always assumed bios and cpuz would be relatively accurate until reading multiple articles and cpu jesus videos on mobos reading low or high. My last setup was a crosshair v. Had a spot on the mobo that could test all the voltages. They were very accurate. New setup, new oc, makes me wonder. I want to squeeze almost full potential out of everything i own haha. And remain on the safe side for longevity. My upgrade schedule is 4 to 5 years on mobo and cpu. Gpus now that crossfire and sli are gone will be every 2 yrs.
If the vcore is accurate, then i have one hell of a chip. I tried 4.5ghz at 1.35v no prime 95 avx stable. I would push the chip and vcore if the actual vcore was what is measured . I figure 1.4 is ok as long as temps are low. At 1.256vcore i get 60c while gaming which is why i question the validity of the reading. Now i know different chips different temps, my 9590 at 5.05ghz all core and 1.475v ran at 45-50c gaming, photoshop, and 60-65c prime95 , which is twice the wattage then the ryzen 3800x with lower heat. The fx setup was only a 360 and super fat 240 rad open loop. Added the extra 240 just because i had it and wanted that extra 2c temp drop.
Thx kindly for the replies.

You're 100% correct. Different CPU's will clock and produce heat differently. Comparing the FX9590 to nearly any current CPU is futile. It's thirst for voltage is legendary as are the temps is would output. AMD has made incredible advancements with their Ryzen family. They are far more efficient and also binned much tighter, meaning less headroom. My 3700x is very similar to your 3800x. For 4.2Ghx I need about 1.125v for full stability. At 4.3Ghz I'm looking at 1.25v and for 4.4 I've tried all the way up to 1.50v but can not find a stable setting. These numbers are all without an AVX offset. Unfortunately I haven't had the time to learn this CPU much more than that. There are more knobs to turn that I've read will help stability and I need to find my Max with AVX offset for applications that don't utilize it.

At any rate, back to your rig. There are a few individuals that will solder leads to specific spots on the board when they need read points on a board. I would NOT recommend doing this to any board you use as a daily driver. 1. It will void your warranty. 2. You run the risk of killing the board in the process and risk shorting the board each time you power it on if you're not cautious. Where to place those leads are critical and you would need to research and dig very deep into understanding the power delivery section of motherboards to learn where they go.

it is crazy how quickly voltage is needed on some of the Ryzen cpus once you get to a certain clock. My 3700x is happy with 1.295v @ 4.4ghz. Going higher it wants voltage fast. I still find it crazy that with all bios settings at stock, the board will throw 1.45v to the cpu- yet temps are still cool with the Enermax Liqmax III 360 AIO. When I work with the bios and get the cpu at 4.4 with less that 1.3v the temps are actually higher than at stock bios settings. I can get the cpu up to 4.6 with temps starting to touch 90c on benches

Thank you all for the replies, and those reading for information.
Ok dejo, glad your chip works roughly the same as mine. Seems like many ryzen owners have had good experiences so far. What motherboard are you using??
I ask because for the most part have been seeing that the people with the best consistent oc are using boards with good vrm and actual layout regarless of the silicon lottery. Unfortunately price does not seem to dictate motherboard component quality anymore. I read reviews till my eyes were bloodshot haha. The tuf x570 although basic seemed to be the best at the 200 price point even better then some of the 300$ boards. Yet there is no llc and current capability for the ram. Which i miss going from a crosshair. If money grew on trees well haha would have the godlike. I do not do any rendering or photoshop anymore only gaming now, so I wonder how much better is faster ram for my uses. A high cinebench or 3dmark score does not seem to really translate into stable fps in games. I play aaa games. Graphics as high as possible to keep roughly 80-100fps even online fps like bfv which runs on ultra. . To me the extra 200$ for quality fast ram might be a possibility if the results were an actual 7-10fps increase as some posts and reviews have stated. Buyers remorse for not just spending the extra 100 at the time of memory purchase . The problem with youtube and online reviews so far is they do not seem to be consistent or focus more on multitasking, productivity work then strickly gaming which i think most people do, hell i could be wrong haha. My circle all game, even my 74yr old father plays daily. The reviews ,posts or videos i have found in gaming for the most part dont make sense as the results seemed to be skewed, either by changing quality settings between eg. 3200 +/- vs 3600mhz+ setups and graphics settings at the same time or the in game footage is different between tests which just changes the results once again.
If I was capable of making my own videos properly then the fast ram purchase would benefit myself and everyone in my shoes looking to either upgrade or building a system. best i can do is do a comparison and just post on here.
Let me know your thoughts oc community, is for eg. 3600c14 vs 3200c16 going to actually improve gps in games when the cpu only hits 50-60% usage and my 2070 hovers around 96-98%.
Once again thank you and keep on overclocking

I see you are using the same board but the wifi version my bad. I also wonder if the tuf could be limited to 4.4 at low vcore compared to a 500-800 $ board. Food for thought.

I'm actually on an ASUS B450i Strix gaming.

If memory serves me correctly You will get comparable results between 3600c14 vs 3200c16 better results from 3600CL14 obviously. (EDIT: mis-read that originally) The sweet spot for these CPUs is at 3733Mhz with the lowest CL you can get. Anything above 3733Mhz anf the IF splits to a 2:1 ratio and you'll take a performance hit. Theoretically there is a speed in which it would be beneficial for this but as my ram is only rated for 3200Mhz (OC'd to 3600) I did not pursue these settings. I'm sure others know what it is though.

I am using the asus tuf x570 wifi as well. The ram I have will run at 3700 @ 14-14-14 timings
