Ryzen 5900X overclocking help

No that’s not high. Those temps are fine. CB is like a stress test in a way and will give you higher temps. I hit 82.

You guys stress too much about temps. We are talking 12-16 cores here. My intel 8 cores used to hit 75+ under heavy load with 8 core easy.

Gaming load the temps are in the 50s for me. You didn’t really expect temps in the 60s running stress test right? Nothing wrong there 😊

Under a custom water loop? :) My 3090 running at 100% doesn't hit that high . And the cpu is running at over double the water temps .

Also seeing 60s in world of warships.

My temps don't break 70c running cinebench using a temporary corsair h115 aio at the moment while my waterblocks are coming in the mail. This is with PBO disabled.

With PBO enabled in Ryzen Master I gain about 300 points or so but temps are much higher:

What volts is the processor running at full load?

For me without PBO: 1.138v and with PBO enabled 1.275v during CB20 load.

From my understanding is that all this is pretty normal and that even idle voltages can be sitting around 1.4v+.
 
No, at idle my 5950X sits around 0.4v and 15w. Zen3 absolutely sips power at idle. At load it goes to 1.45v but of course that will depend on your PBO and curve optimizer settings.

I am seeing it sit around .5-.8v area and some random spikes to 1.4v etc with windows just doing whatever. I never see above 1.3v load though which makes sense to me because 1.4v+ load on 12 cores is kinda crazy. I haven't really touched anything except set my ram profile.
 
Oh sure, it'll go up to 1.4v or whatever when a background process triggers usage, just not when truly idling. In CBR23 multicore tests my average is 1.18v on 16 cores. I have a very modest PBO at 162w PPO, 115A TDC, 160A EDC and CO at -0 top 4 cores and -25 on the remaining cores. And cooled by high-end air, NH-D15.

Cool thanks, I still have to play around with this curve setting option with these new chips.

No I have 360 AIO, custom loops will definitely get you little better temps then I do. I have 3090 FE. 3090 FE doesn't even break 60s in games even with 114% power. +150 on core and 400 on memory. Truly impressive for air cooling.

Games both are in 60s max. AIDA 64 stress test for CPU and memory average temp is around 81.7c for the chip after two hours of stress test. It runs around 4575 all 16 cores under stress test with custom settings. I mean for a monster chip with 16 cores chugging along at almost 4.6 under load its pretty impressive.

I have never seen all core load remotely close to 1.45v. Single core it can hover pretty high and that is mostly by design but all core it dips below 1.35v almost all the time with PBO on. I have curve optimizer set to -12 now. -15 wasn't stable, then I dropped to -10 and it passed and now -12 passed so far for 2+ hours. PBO ON and +200 on the core.

Here are the volts average and its been running aida 64 for 2+ hours now. Its mostly hovered above 4.6 during the test with above settings.

if I leave auto on PBO which is off. It will boost to 4ghz all core and the voltage is below 1.2v from what I remember so really depends on what you are happy with. But I am happy with the settings so far.

I'm saying mine is under a custom loop lol.

Voltage by itself doesn't matter. It's voltage plus current (+ temps) that matters. Up to 1.5v under low current (so low load) is perfectly fine. High current (such as all core load) is where you shouldn't be running above your FIT voltage. This seems to be in the 1.2xx range for 5900x (although the absolute max may be slightly higher). Temps over 90c is where things get dangerous as well, which is why it AMD throttles there.

Under cinebench my volts are around 1.2xxx range. So yes it does go down as with higher load. It’s probably using Avx. With cinebench r23 did see my clocks did to 4550 all core from 4600+ under Aida. So cinebench r23 is definitely higher load it seems.

Under aids volts around 1.31xxx average. Under cinebench it was 1.2xxx range.

Single core cinebench load is 1.4xxx range.
 
I had to manually set volts to 1.2625 for it to calm down. On auto PBO or even with -10 all core I was getting 83 C temps. Now it hovers around 80 C tops when running Immortal Fenyx Rising which is by far the only game that runs hot af.
CB runs at max 70 C but my temps are super low also because CB only puts 4.2 GHz all core (some known bug w/ MSI motherboards). If I set volts to Auto, my CB runs are fine and I can score 8690 or something but then my temps shoot up. For now I have kept it w/ direct volts and PBO w/ +100. Nothing else is changed.
 
Like I said, my chip runs at 1.18v on multicore benchmarks. The 1.45v was a single thread.

My clocks and PBO are very conservative right now because I had the WHEA reboots on idle issue and it was a total pain in the ass. AGESA 1.1.9.0 seems to have fixed it and I'm stable for just under 4 days now. Once I hit a week I'll mess around with more aggressive power settings.

Yeah my chip idles at higher voltage , guessing that's the 1-2 cores spiking up for background processes
 
Yes Ryzen ramps up and down extremely quickly. It's pretty sweet, when a buggy AGESA doesn't cause it to reboot.

you can launch hwinfo64 and see it happen. It really ramps up and down. but if you look at the average volts you will see its around 1.XXX range when browsing or idling. Board makers still need time I think for the new Agesa with curved optimizer. Asus currently has it under AMD overclocking and then PBO. But there is also PBO section under extreme tweaker which is easier to get to but no curve optimizer there. Its like setting up PBO in two places. Kinda annoying I have to make sure they are both the same or which one kicks in PBO. I do know curve optimizer does kick in because it does give me some instability if have a high negative value. -10 seems to be rock solid. It is labeled as Beta Bios so pretty stable for that, but waiting for them clean it up little.
 
About to dive in and start tweaking my new rig - just finished building it this afternoon. (5900x, Strix 3090, Crosshair VIII Dark Hero, 32Gb G.Skill)
Everything still stock/auto in BIOS right now (3101 Beta firmware). The CPU idles at 24C and hits 54C under full load.

Curious as to what sorts of benchmark numbers folks here are getting with their 5900x systems once dialed in. So far, I've just dialed in the G.Skill RAM to its stock settings: 3600 DDR4 CAS 14 (14-15-15-15-35 @ 1.45V) with an 1800 FCLK. All of my other BIOS setting are still pretty much sitting on "Auto".

GeekBench 5 score: Single Core = 1724 Multi-Core = 14780

Edit: Played around some more with various settings. Turned on the DOCP for memory and left the majority of the OC items on "auto" which the Dark Hero seems to handle quite well. If you aren't after the ragged edge and just want stability/performance, it seems to do the job. Very happy with my overall performance and temps.

Latest GeekBench 5 score: Single Core = 1728 Multi-Core = 14996

Once the v3101 firmware comes out of beta and some more OC guides/software updates hit (like the Ryzen DRAM calculator utility update for Zen 3), I may re-visit the OC settings and push things a bit more... but for now, this thing just rocks!

Cancelled my order for H150i Elite Capillex for now. Other pros:
Silent compared to my Phanteks case fans
All LL fans so all lighting is same and all running 1250 RPM
No need for MSI dragon center horrible software as case RGB can be controlled with buttons on front panel

Having some second thoughts about this configuration. All my components except CPU are running hotter now. Ram is touching 59-60 C. Even saw the chipset fan come on. GPU also hit 68 C something it had never done before since I got it.

Reverse the top fans so they are blowing cool air in? :) If you're using dust filters it would be better anyway , leave only rear as exhaust
 
Is your ram unstable? If not then don't worry about it since those temps are well within safe limits. I would also not worry about your GPU temps because they are still fine. Yeah of course its gonna be a trade off to some extent. I personally ended up putting a 80mm fan over my ram because I found keeping the temps down helped with my B die stability this also had a secondary effect of blowing some extra air over my VRM area and even the top m.2 which was nice. This may or may not be needed depending on how hard you are pushing your ram and how much volts you are throwing at it.
You wanted lower CPU temps and I would say this was a huge improvement

Someone else also recommended the same. Will do it tomorrow morning. Will kill the disco vibe though.
My ram and overall computer is stable. No issues before or afterwards.

If those are Corsair QL fans, they have the same LED setup in reverse ( look at my pic, QLs mounted in a pull setup)
 
No I used LL fans as they perform slightly better plus I like the colors better. QL is too bright for me.

Happy New Year All!!!...

This is it... for gaming at 1440p and up, GPU will be taxed the most. However if you are doing a lot of CPU intensive tasks, maybe there is a benefit of it.
Regardless I recommend undervolt your 3080 TUF. My kids have been gaming 1440@144 for the last 2 days with 1920@875mV with no issues.

If you decide to keep front mounted AIO, it is recommended to put pipes down :p

Not this stupid video again. It doesn’t matter for a 360 rad. I am going to flip the top fans and see if other components get better cooling.

KickAssCop, I'm really surprised your CPU temps are running that hot on water. Have you ever considered a custom loop + push/pull with shrouding around your rads? :)

Your RAM temps also seem quite high - perhaps you have a dead spot on the air flow around your RAM? (Especially if you have all your fans venting outwards.) The 8 GT 1850 Nidecs at the top of my case are always pushing/sucking air upwards - which really helps with the overall internal case airflow (and that's not counting the other 3 fans inside which are also moving it around.)

Not a bad little writeup to get started. The biggest issue is memory stability. I'd check and double check that your memory is stable because Ryzen is very susceptible to memory instability.
Click to expand...
One thing that I will add, just not sure if it affects all MBs, but it definitely affected the hell out of my ASUS Dark Hero: Once you load up a new BIOS FW, MAKE SURE that you either force a "clear" of all BIOS settings or do a complete "Reset" of all settings to their default "stable" state. Afterwards, THEN go in and start setting them to what you want.

I had flashed to the latest firmware and then for the life of me could not get my memory to remain stable past 3200. (It's G.Skill rated for 3600!) Was pulling my hair out. Everything I tried would result in errors/blue screens. Once I reset/cleared the BIOS and then went in and adjusted settings, it became rock solid.
 
Reversed the fans and tried to do some tweaking with speeds (put the rad/top fans at 1100 RPM) and back fan at 1400. Temps are either not changed or worse.
CPU same as before around 71/72
GPU 3 C more from 68/69 to now 72
Chipset also getting a bit worse to about 70 C turning on the AUX4 fan which is chipset fan at 1900 RPM
RAM also slightly worse by 2 C

1-2 C I am not bothered about but seems consistently worse temps than having the top fans as exhaust

I literally give up now. I have no way to explain anymore wtf is going on with my computer.

This is after putting rad on top and again playing 30 minutes of Immortals Fenyx Rising. This computer has a complete mind of its own.

As you can see CPU is now running at 71 C. However, everything else has cooled down including RAM, GPU and all components. Also the Auxfan4 didn't turn on. I am actually doing nothing different except changing rad position plus playing Immortals Fenyx Rising in exact same area (area 2 for 30 minutes each time).

I am sticking with what I have now and calling it a day. It is ridiculous. Will play some more when new bios is out.

Adjust Ram! Set PBO to ON. Reboot and enjoy. I have stopped messing with anything else. There is really not much difference. I just make sure my ram is tweaked and has the least latency with DRAM calculator and enjoy the beast lol. 50-100mhz on CPU here and there isn't worth peace of mind.
 
No real change with the new bios. Comp working same as before. Haven't tried higher IF though which I will do after I find my flathead screwdriver lol.
