I wouldn't think so, my 3800x ran hotter then the current 5900x.
I just got my 5950x, also replaced a 3800x. I'm getting better temps on the 5950x than i did on my 3800x. I severely lost the silicon lottery on my 3800x though, max i could get was 4300 all core, in stock form, it never boosted above 4590mhz...

Super satisfied with this 5950x, still dialing in the OC though.
 
Just finished building my system with minimal tuning.

Cooling: Noctua D15 /w conductonaut
Temps: 86C playing MS flight sim
Core: PBO +200mhz (auto boost to 4.7Ghz single thread or 4.4Ghz all core)
Voltage: Auto
Infinity fabric : 1900mhz (buildzoid told me to go offsync due to slower ram)
Memory: Hynix AFR B0 3000kit @ 3333 CL16 (ram from 2016)
GPU: Zotac 3080 trinity OC

I am happy with the current performance with MS flight sim with 50+fps @ 4k ultra
not sure if more all core overclock or faster ram is going to further increase my fps
more tuning soon
Im sorry to say thats a horrible score, you must be clock stretching.
I would play with Curve optimizer and lower the 200Mhz for sure.
 
I'm experiencing a weird issue when enabling CCX OC in my 5950X. Bench scores are just right when everything is at stock, but as soon as I enable CCX overclock, only half of each chiplets reach the selected frequency (4.5 in this case):



I'm running this cpu in an Aorus Master X570 in which I tried a 3950X before with no issues playing with CCX. Any ideas? :(
 
Hello.
Glad to see this thread as this is my first AMD since phenom ii so i am feeling a bit lost right now.
So I got the 5950x with x570 hero wifi.

first of all .. Where do i fold the individual core temps?
i used to do it with hwinfo for my Intel ones but I just don't find them in that app.

Are there and guides around to get me a base to start from?
thanks!!
 
Hello,
What do you think about the H115i RGB Platinum for a 5950X ?

does someone use this combo ?

is this cooler enough to cool the beast at overclocks with Vcore 1,3V to 1,35V or would you recommend definitely a 360mm as Artic Freezer II 360 ?
 
This is my result after playing around for 3-4 days

Managed to get 4000mhz @2000fclk but it lowers the latency by 4 (59.8ns),but it does increase Read,Write and Copy. Now I'm running 1.287 voltage if I go to 4000mhz @2000clk it needs to go up atleast to 1.350-1.400volt which gets to mid 80's to low 90's with NZXT Z73 running 3 Noctua NF-A12x25 fans at full speed

RAM - Team T-Force Xtreem 4500mhz 4x8GB

3800hz at 1900fclk and PBO enabled

4000mhz at 2000fclk and also same PBO enabled

Ever since I started using AMD Ryzen since my first Ryzen 7 1700 I always used manual overclocking as I prefered the all core boost to single core performance. However, currently with my Ryzen 9 5950X I've found that running the processor stock with PBO almost give me the same preformance in CB20 as I would get with my processor running 4.6ghz.... Yes I can push the processor higher as this is only using 1.3375 vcore but I prefer to keep the processor from reaching 90C CCD temps.

So here is firstly PBO first run, the second is when setting realitime and the last is with the processor at 4.6ghz, unfortunately this was using 1.25vcore so running realitime did not work.

Are you running any software-based CCX overclocking tools? I noticed that the Asus Zen2 "worktool" would have this effect on Zen3 CCD overclocking. The older quad-CCD tools seem to mess up with Zen3 due to the different architecture.
If you're doing it with BIOS it might be a bug that you'll have to wait for Gigabyte to fix.
 
Managed to get 32100 CBR23@4750@1.3v fixed with WC + 480 rad 10C ambient. Temps must not exceed 70C much or it will crash at that voltage after 8 or 9 minutes. Higher voltage gets too hot.

yeah do a ccx oc 4750mhz and 4600mhz and btw 1.3 is high, very very high. the ideal voltage is 1.25 volt. which a ryzen 9 5950x should achieve in all cores. My ryzen 9 5900x was able to achieve 4700mhz and 4650mhz in ccx0 and 1 at 1.25 volt with llc3.
 
4700 on 1.25 yes but not @ 4750 on my cpu. 5900 will be cooler than a 5950 so its easier to achieve stability. Also not sure how good my sample is. I just wanted to see whats the max all core under sustained full load.
 
Im just using curve optimizer. I just dialed negative and 20 for all cores, ...done. Resulted in an allcore clock of 4450-4500 in Cinebench instead of 4150 before where i already hit powerlimit and about 100-200mhz more in Games. Using 5900X.
Im happy with it.
 
can someone please answer a quick question regaurding the curve optimizer.... what is the "-" (negetive) number mean? EX, when someone sets -15 or -20 for all cores, what is that actually setting? just dont understand...
 
I am annoyed with my 3900x because of its poor thermals and oc. Planning to replace with 5900x. Have both thermals and oc improved with 5900x? The max i am able to run is 4.4 on 2 ccds and 4.2 on the other 2. But this is not stable when benching hard like multiple CBr20 runs or anything that uses all threads as the temp limit is reached in few minutes. I am seeing 4.6-4.7ghz all-core on 5900x.
 
I've heard some rumors that rising higher voltage than 1.25 for daily use will degrade cpu, how it is in practice? Actually found sweet spot for my 5900x on 4,5GHz for all cores with 1,275v with turbo llc ( aorus master mobo ) and was reaching around 75C max.

It's fine and under high current loads there is probably a vdrop. If yours CPU will degrade on 1.3V it would also under PBO an you just got a poor bin. With 2 chiplet cpus you will be first temperature limited. I think that 1.25-1.275V on vdrop are fine.
