Diagnostic is only a rough estimate and it'll change it's results based on your LLC or other settings. Tune is the real thing and take over an hour. Below are my results

yea, all in all with same PBO settings these processors take the same amount of power, just 5800X pushes it all to one CCX (I guess inferior silicon quality) while 5950X with better silcion distriubutes it to two CCXes and also becasue of that 6 core CCX 5600X and 5900X should have noticeably...

Oh you can't apply them all at once, and you have to test what's working and what's not ;) some of the timings are connected, so just leave everything you don't change on auto.

oh that's indeed Asus default :) great results, I may need to check this new BIOS as I have very similar motherboard (just full ATX version) if FCLK is stable you can try and lower some other timings, get Dram Calculator for Ryzen, check some tutorials and slowly start tightening these secondary...

Please add ZenTimings screen, it summarizes all voltages and memory settings pretty well. Unless your voltages are way off you can run it this way, I must say you're pretty lucky if it works out of the box ;)

Exactly this. If I recall for 5800X (which is 105W TDP CPU) PPT - 142W TDC - 95A EDC - 140A Setting this to motherboard sets PPT and EDC to something close to 200W/200A, no way CPU will draw this much but possibility is there. Performance gain is minimal compared to all this extra power. On the...

/dev/null I did some more testing. Changed PBO to advanced, set limits to motherboard, +200MHz etc. and scores were instantly lower around 5800 points, boost clocks were also lower. Set it back to auto and I'm back at little over 6k points. I read somewhere that with recent BIOSes you need to...

Most likely, you are also on Asus board so they should act similar. This guy had similar issue, somehow scores for same CPUs were worse on different motherboards, no idea if he figured it out.

Same :) I was fighting with my ram for weeks and I'm still not happy with the results, and BIOSes are super bugged right now so experience may vary depending on the motherboard/bios combo you are using, make me miss my Intel platform at times. PBO vs all core OC that's yet another level of...

I use ASUS TUF GAMING B550-Plus with 1401 BIOS. PBO is on Auto, whatever it means for Asus. One time I touched PBO was on previous BIOS but only to enable ECO mode limits to test something and then my Cinebench results were lower, initially 5500 points, but I managed to tweak it a little to get...

/dev/null I just did few runs of CB R20 All cores are boosting to 4,572.3MHz and stay there for most of the test duration, if it drops it drops for a second to 4,547.3MHz but then it's right back to 4,572.3MHz. Temps are reaching 80C after 3 runs. Scoring between 6066 to 6092 in these runs. Room...

What do you mean by PBO off? You went into BIOS and changed it from Auto to Disabled? I get a little over 6k points in multicore CB R20 but I never bothered to alter PBO settings, they are still on Auto, and I'm not really sure if it means disabled or enabled for Asus, I'd guess it's enabled but...

I'm using D-15S on 5800X which is a little harder to keep cool than 5900X. It's not overkill at all.

That's part of the picture. While all you said is correct, it's also allowed to use the same TDP as 5900X so it just puls more power for it's size, and that makes it really hard cool. If you allow stock PB & lower limits then lots of people struggle to keep it under 90C during single CB R20...

My bad, there's few 240 sets there. Still I'd not save on cooling for this one, unless you are seriously limited by space and 240 is biggest you could fit. If that's the case then there are better 240 coolers e.g. https://www2.arctic.ac/liquidfreezer2/us/liquid-freezer-240-us/

oh sorry ;) 5800X is pretty hard to keep cool and I've seen a lot of mid range AIO struggling. Anything below 280 is not even on AMD recommended list. https://www.amd.com/en/processors/ryzen-thermal-solutions I haven't seen any significant difference in performance, if you get good 5800X paired...

These are hard to compare as new i9 is going to be 8 cores only. You really can't compare it to 5950. Seems like Intel needs 8 cores max to push for higher clocks. If you want to wait you'd have to wait for DDR5 platforms from both AMD and Intel, and that's a long wait. So I'd just take whatever...

Sure, this may make little sense but it's my way of thinking, I change mobo/cpu only when I really need to. So if I had RTX 2070 or equivalent and old, lets say 4c/4t platform I'd still upgrade to something like 8 cores. I7 or R7 and left GPU alone for at least a year. Doesn't matter if CPU is...

yea that's good idea, CAD_BUS you need to touch when you try to disable GMD mode, for most other cases it's better on auto

16GB sets are little harder to set, and this calculator is not always correct ;) Also about voltages, my b-die set has two XMP profiles, one for 1,35V the other for 1.45V stock, so up to 1.45V if the cooling is ok you should be good. Besides errors caused by overheating are usually easy to spot...

well, some say that 200MHz steps are for Intel and AMD really likes 266 so it's 3200/3733 or 4000 ;) I'm really stability freak other than anything else (my old Intel set had like 3 BSOD during it's whole lifetime ~5 years and all of them were caused by me) so I can live with 3733 and tight...

what sort of WHEA you're fighting with? whea 19 bus/interconnect warning one? if they happen during idle in high numbers it may be hard to correct, for me anything above 1900 (even 1933) and I have them at idle, high numbers and memory related benchmarks show worse results. I can play with...

Hahaha ok ;) I saw few videos of this guy, lots of words not a lot of content. Still if I could get 5800X for decent money I'd take it over 5600X and just use ECO mode if my cooling is not sufficient. It basically turns it in 8 core version of 5600X (or something like 5700X if AMD ever release...

Thanks! that's good summary. Guess I'll give 3733 a go and work on lowering timings to CL14 rather than trying to figure out why at 3800MHz I still sometimes get WHEA error. AGESA 1.1.8.0. for ASUS improved things a lot. After update at 1800 FCLK I can run tests for hours,which previously would...

Is this really 266MHz stepping important? My 5800X with ASUS TUF Gaming B550-Plus and Patriot Viper Steel 4400CL19 is currently running at 3800MHz, CL16 and rather tight timings. I can't push it to 4000MHz with current BIOS as it's too unstable due to WHEA but I can drop to 3733 and tighten the...

Ok, that's super high idle so I'd guess there's something wrong with BIOS/default setting or the cooler itself. But! strong disclaimer here cooling performance can be hard to judge. On some motherboards with stock/default settings it'll reach thermal limits without any visible performance gain...

I got what you say but it's not the complete picture. Check this text https://www.gamersnexus.net/guides/3494-amd-ryzen-3000-undervolting-offset-override they mention it somewhere on the way, and there were more reports of the same since then. Zen 3 is no different. If you push it too high...

that's part of the picture, but you may end up in clock stretch situation where you'll see high boost clocks reported yet effective clocks will never go near to these values, it's best to check all OC with some benchmark with good scaling, it's super easy to get cheated by this rather smart CPU...

same goes for single core benchmarks? does it boost single core correctly or also only 4GHz? rule of thumb is that all core OC will work great for workload, video encoding and multithread benchmarks ;) you'll get better results with less power, but if you want gaming performance you have to...

I switched from Intel 6600K Z170 board to Ryzen 7 5800X B550 board. Only thing I did was reinstall chipset, graphics and sound card drivers ;) It worked like a dream for a week and then I broke it with memory overclocking :D so yea you can use your current system, eventually you'll break it and...

Memory clocking with all current BIOSes is a bit fishy. Some people could go to 3800MHz no issues, all on auto. Some couldn't set anything above 3200MHz without at least a bunch of WHEA errors or even lack of post. It's less of a memory issue more of FCLK keeping up 1:1 with MCLK. In worst case...

yea + the buggy BIOS ;) it was the same with Zen 2 platform, for me it was a good lesson that you may seems stable (some people with this issues pushed hundreds of hours of workloads and gaming through their machines) and yet, there's something fishy in the background, not enough to impact...

I'm referring to this type of errors. It's not mine, I got rid of mine, at least with current setting, but before that I coud pass OCCT, Prime95, endless loops of Cinebench or TM5 no issues, yet windows event tracker was recording these warnings. BR

Question. What's your stand on WHEA errors that tend to plague Zen 3 platform with current BIOSes? I spend last weekend tweaking everything I could think of to get rid of them and I think I succeed. Problem is, before I noticed, I could run most challenging TM5 for few hours, no memory errors...

If your scores falls into what everyone else is getting (they are not lower because of lets say CPU running in ECO mode) then you have great cooling solution or great sample ;) many people hit thermal limits during run R20 run.

MSI had some rough start with Zen 3, most people had their configs unstable at memory clocks higher than 3200MHz with IF 1:1 but it's fixed now and a friend of my is running MSI with 3800CL15 memory, no issues. For easy memory setup & best performance you should aim at 4x8 or 2x16 (dual ranks)...

I'm running ASUS TUF GAMING B550-Plus with 5800X, Patriot Viper Steel 4400 CL19 memory. Ram is tricky as with current BIOS chances that it'll go 4000MHz 1:1 with fclk are slim. But it's rather easy to set it to something like 3800CL16 or CL15 if you have more time and patience. I'm not sure what...

Hi there, I need some advice on Zen 3 LLC settings with Asus board (I guess they are going to be pretty much the same B550/X570) CPU 5800X, RAM Patriot Viper Steel 4400CL18 -> currenlty at 3800CL16 IF 1:1 PBO enabled. I don't plan for CPU OC, even if, it's going to be only for testing...

it's either voltages or newer BIOS, my Asus sets all other voltages pretty high so the only one I needed to adjust was VDDG CCD. I can now think of lowering some of the values, but they are somehow connected so if you touch one you may mess up the whole thing. And yes these 4 are the main...

FCLK 1:1 requires some tweaking on all motherboards, for some it required BIOS update, e.g. on my Asus TUF Gaming B550 voltages were set by default as attached below (auto voltages are actually 1.1, 1.0, 1.05, 0.9 but there's some voltage drop as LLC still on auto). I had to tune VDDG CCD to...
