I have a 5950X. I use a Noctua NH-D15 for cooling. CPU voltages are stock.

Motherboard is Asrock X570 PG Velocita.

Chasis is a massive Thor tower with lots of fans including the largest ones on the side and top.

What I HAVE tweaked is the power to the fans (CPU and chasis) based on CPU temp, and I did it all within the BIOS. I had little luck and satisfaction with the Asrock software.

I don't hear any fans during "normal" operation.

The fans spin up and become audible when I put the system under load, such as running ffmpeg for video creation.

I have four sticks of memory totaling 48GB. I run it at "factory OC"; I forget the name for it (XMP?), but it's the timing and speed the memory is rated for, which is higher than what the motherboard would default to.

I live in southern AZ and the ambient temp in my room in the summer can be in the 90s. No overheating issues, at least on the computer side of things. :)

Well......sigh.....

Still having issues. I think for this board that even being at -.075 might have been too much for the RAM to be "XMP" properly. Had a total power off shutdown last night while temps and everything where fine. 6008 IIRC, but pretty similar to 41. I also had some RAM error ID showing in Reliability History. There is a separate area in BIOS for the RAM related voltage and that is set to auto.

I have turned up to -.050 offset and kept the XMP. Temps are slightly warmer than I like but still haven't seen over 76 be logged. I am completely procrastinating about breaking it down enough to repaste and move a fan.

I rather wonder that even though this CPU is compatible with the mobo, there is only (1) 8 pin instead of two. Makes me consider that there could be a transient load looking for a well of voltage/amperage that isn't available due to that constraint. Basically, just rambling in that respect.

im only on 1 8 pin and im fine. with more cores and 4 sticks of ram set your ram speed to 3000 if it isnt already.

what ram are you using.

Currently a set of SP Value Gaming 3200/16. These come up for a great price and have worked pretty well for me so far, but all previous systems were lower power base clock setups. I have a set of G Skill Trident that are 3000/14 which were that whole 2nd gen "Ryzen optimized" marketing-speak. It has been a very reliable set for me in most cases, so I might try that.

I cannot recall the voltages on either one off the top of my head, so will have to look in CPU-Z right quick.

from my experience msi motherboards and ryzen cpus are picky with ram

my current ram is duel rank 3000 4 sticks cl17 ( kit)

i think if you just lower the clock speed of the sp ram to by 200

run the 3d mark benchmark demo on steam should be enough to see if its stable.

check the motherboard bios and make sure it doesnt have a msi version of turbo boost.

e.g my asus board had a asus version of procession boost of its own design and amds actual procession boost.

i turned off asus version and left amds on it hasnt pushed voltages up.

under amd overclocking set the procession boost to stop boosting at 85c ( dont trust the board to do this on auto or advanced.

basicly manufacturers like asus and msi have there own specifications outside of the factory settings of ryzen cpus to keep voltage pinned. i suspect your board is trying to override your undervolt when its motherboards pbo drive is set to push it as high as the board can take it.

option 2 is to just outright disable procession boost ( this wont stop the cpu hitting 4.9 it will just tell the motherboard to chill out and stop slamming my cpu with voltage to go beyond the max turbo.

if you turn off procession boost and then see if you can drop the voltage to 0.1

( yes im determined to get that cpu working on your board even if i have to go find a similar mortar board and do my own Frankenstein testing lol.

( side note this is why i never go near msi boards ( asus isnt better but ive managed to get its quirks under control) )
 
Last night after reading through some of your suggestions I went ahead back up to the .075 neg offset and ran the RAM speed back down to 3000 as suggested as it makes good sense anyway. I did not experience any crashes or issues. It is a bit cooler yesterday and last night than it has been as well.

Yeah I'd still look into the boost and disable it it's basically out of the manufacturers spec to run a turbo boost mode which is on by default.

Still unsure why it can't go to 0.1 as your vrm is either better or equal to mine so should handle it. If 0.1 isn't available see if it is just a code error and try 0.125 negative
 
Wanted to follow up on this thread a bit as an update.

MSI released the (non BETA) version of BIOS in April with an update here in July which is 2.90, the BETA I had been previously using from 2024 was 2.91 which I am assuming has some known issue since they "backed out" a bit. New AGESA combo update also.

Since doing the undervolt and turning off PBO the system has been rock solid but there has been a notable latency and some in game issues in menu and so forth. FPS have been in a good range and for most games things have been fine. I have been having consistent issues with BG3. I may have already mentioned a RAM swap to a lower latency CL14 3000 kit from G Skill. After having installed the newer BIOS I went back to the default settings on voltage and PBO, tuned fan curves on PWM/Smart and so much as I can tell it is a significant improvement in both latency and performance.

It is summer here and tomorrow daytime is going to tell me much more. Ambient is typically around 74*(F) but around mid afternoon to early evening the temps will climb a few degrees. My own experience has shown previously that indicated temps tend to show far lower than 'max' as I have never seen the CPU go 95 before the system shows various sign of instability or a crash which was the purpose for the thread in the first place. More testing is obviously going to be needed.

If this goes back to the issue plagued stability of before I will probably bring an AIO back into the equation. In spite of the cost of the air cooler, which was also part of that initial desire, I may just be too wishful about its ability to cool such a CPU. More testing will reveal.

I personally don't have any issues with aios while using these CPUs I'm not sure how reviewers are doing there wizardry but even dawvid does tech stuff doesn't get how some of these are rated for 250w-300w when they struggle to cool even 150w.

Hi Punkncat
I have a 5900x in custom loop and my son's is a 5900x with a cpu(only) custom loop that is on the same mobo as yours.

My specs; asus Rog Crosshair Hero 7 , 5900x with a Heat Killer iV Pro waterblock
Evga Rtx 2080 Ti Ftw3 with a Ek Vector waterblock
3 rads 360x30 top, 420x45 front, and a 280x 60 in the very bottom of a thermaltake core x71 case
Ek Tbe 300 D5 Pwm pump
All Noctua Ippc fans
G.skill Trident Z Rgb 2x16 3600 cl16 running @ 3800mhz. 16 16 16 36

My Son's Specs; Msi Tomahawk Max wifi 5900x with a Optimus Fondation am4/ am5 waterblock
Cpu Only custom loop. ( no Waterblocks for the Gigabyte Rtx 4070 windforce gpu )
Ek Tbe 200 pwm D5 pump
2 rads Hardware Labs 360 and a HwL 480 ( way over kill for No Gpu AT THIS TIME) with Iceburg Fans
G.skill Trident Neo 2x16 3600 running @ correction 3733mhz 16 16 16 36
in a Corsair 7000D airflow case

Pic order Idle - cbr23 - unigene valley

Currently my system is busy doing stream recordings that has been running 24/7 for almost 3 weeks now.

As you can see in the snip the 5900 hits 5.5 GHZ at times with the system working just over idle approx 15% load.
Watching the Cpu core voltage sv12 tfn is ranging from 1.42v-1.47v

During Ghost Reacon Wildlands / Breakpoint cpu temp runs 52-55c with the Gpu 42-43c depending on the ambi temp.

Before the custom loop it was cooled with a Corsair 360 Elite Caplex and temps was 86c running CB R23 then I tried this vid as a guide.
View: https://youtu.be/nvVs_6Sr3wU?feature=shared


It lowered my temps a good 10c during cb r23 and was hitting 5ghz more often in other usages.

I also passed that vid to a friend that is on 5900x and a corsair EC 360 which does Ms FS 2020
with no stability issues with temps in the mid 50's during flights.

When my sytem gets finished I will post back what the sv tfn voltage is at Idle If you want.

If you are thinking a Aio That Be Quite silent loop 3 is at least refillable which is a easy Big Help.

Hoping maybe something here helps
Have a Great Weekend!!!!!!!!!!!!!!!

Hey @Crosslhs82x2, thanks for checking back in.

Since the BIOS and AGESA combo update mentioned above I was able to do away with the under-volt, turn PBO back on, and with some fan curve adjustments have just been letting it eat.

I haven't gotten so fancy as to add a monitor to (see) HWI, but have seen some increase in CPU voltage in RIVA amounting to ~25W while in game. Temps went up a few degrees but haven't reached any level that has caused issue so far. This is the hottest part of the year here, so if were going to....

I am seeing clock speeds touch 4.95 but by and large are 4.7-4.8 in most of the current games I am playing. Mostly just BG3 right now. I have seen some meaningful FPS gains and actually been able to do some mild tweaking with the settings upward. System has overall been exceptionally stable, no crashes, nothing to report in Reliability History or Event Viewer.

Of note, and not sure it was mentioned but I also did some fan reconfiguration. (011D mini case) I dropped one (of previously three) 120mm fan from the bottom and replaced the two side 120mm with two 140mm fans. I have two more 120mm pretty much centered over the Dark Rock up top, and then one 120mm in back. Bottoms and side in, top and back out. Where it doesn't particularly make logical sense, the lack of one fan and having two larger but slower fans seemed to help a lot with flow, temps, and noise.
 
Glad to hear things have settled down and it's running better!!!!!!!!!!
I have a portable a/c unit in this room and my son's room because the main apartment window a/c does nothing for the bedrooms, glad to have the a/c but don't like the electric bill in the summer.
I let the horse's run wild on the cpu because of the water loop but still have to Undervolt the Evga 2080 ti to keep from tripping the room breaker if the a/c unit is compressing while gaming.
Oh well hopefully it will last another 4 yrs. Maybe Nvidia 70-80 series Or Amd ???? which have come a Long way from years past. I hope their prices are cheaper then Nvidia at that time, as I will have to get 1 that I can get a wblk as well.
If I had to buy another Aio theres a pretty good chance it would be that Be Quite Silent Loop 3 since it is easy to refill to help prolong its lifespan.
If you ever need to have a secondary close to system check or check a reaction to a system change hit me up
and will have my son give the info!!!!!
Have A Great Weekend!!!!!!!!!!!!!!!!!
