5800X Boost set to 5050Mhz all cores with AMD Curve Optimizer

[alec]

No it still goes up to 4800 (5800x), just not 5000+ anymore. It's normal default behavior, +200mhz has no effect. I need to go back to last beta BIOS which worked properly.

I misread 4800 for CB20 score.
You are lucky to see clocks reaching 4800 in MT cinebench actually. For a heavy multithread work like this, 4.65 is more common, 4.75 maybe with generous CO.
Also don't pay too much attention to clock number, the score is what matters and what shows you if something is wrong.

PBO left on auto for me scores around 6000 multi thread on a 5800X.
Max clocks might be 4850Mhz accross all cores but not at the same time. I can only get close to 4750Mhz all at the same time with a manual all core overclock.

This is what it looks like usually for me with PBO on auto (4525Mhz / 4550Mhz all cores)

Hey folks so got my 5800x up and running last night and damn it's hot what settings should I use in Curve optimiser for lower temps and still maintain 4.85ghz boost for games not fussed that much about multicore.

 

[alec]

should I use in Curve optimiser for lower temps

won't lower your temps, will run faster at same temps.
Need to reduce PPT limit (and maybe EDC) to lower temps while keeping boost for games

 

[lloydcars18]

@alec why wouldn't lowering the voltage lower Temps im not going to be using PBO2 just Curve Optimiser my CPU is hitting 75c will just browsing the internet?

Negative curve optimiser value lowers voltage at every clock speed, yes.
But clocks are dynamic and depend on load and power/temperature limits . Changed curve means that CPU is more likely to hit higher clocks (and pretty much same voltages as before). End result being more performance, but mostly same power/heat.

Not worth it then tbh guess il need to get a better CPU cooler as this one is a hair dryer the wraith prism RGB saying that only using PC for gaming and Multitasking so 70c will still be ok I guess.

so i got RYZEN 5800x 16gb ram 4400mhz i run that ram on 3600mhz with lower timings i got
ROG CROSSHAIR VII HERO x470 i got 240mm AIO i just wonder what will be safe all core overclock where to start

 

[RavenXXX2]

Any reason why my 5600X does not ramp up voltage when running single/low load thread workloads with curve engaged. Makes system unstable when trying for 200 PBO, high loads voltage ramps up.

Hi,

who else has been facing unexplained, random, rare and far in between restarts that dont seem to have any clear reason?

have you been able to figure it out?

I had random reboots on a non beta BIOS. Updated to a beta and the crashes stopped (MEG Unify X570)

Cooler could be limiting your CPU performance if its throttling due to heat. The other thread, the stock multicore R23 score was about 1000 lower that what it should be.

Try Timespy. What CPU score do you get?

 

[lloydcars18]

@Guest2 11206 is my CPU score on Timespy

curve optimizer doesn't lower temps, it keeps the same temp and just tries for higher clocks - what you want is a undervolt

That's where lowering the PPT TDC and EDC comes in since the 5800X gets the same values of these as the 5900/5950X despite only having 2/3 or 1/2 the cores so it tends to pull more power than required which also makes it run hotter with all the heat being on a single chipset and thus reduces the clocks.

Have a look in the bios for the 95w Eco mode and try this combined with the curve optimiser as it reduced temps while improving performance.

 

[Guest2]

@Guest2 11206 is my CPU score on Timespy

Its probably not boosting to what its capable of due to temp.

Should be closer to 13k

 

[lloydcars18]

@Guest2 yea true that's for Multicore though For gaming im sure its boosting fine?

I've been reading reviews of the 5800x and there timespy CPU scores are around 11500-12100 so im not losing much guess u have a good chip or are overclocked.

What do you think about this Cooler or should I get the 360mm one for 10 quid more?

Depends on the game. Some will use more cores than others.
I am on 1900 IF, DDR3800 so maybe it's that improving my score slightly. I'm running the CPU on PBO defaults

Never heard of that cooler, I would go for an Arctic Liquid Freezer II. The 280mm is £90, 360mm is £100.
Just make sure it fits in your case / next to motherboard. I bought the LF 280mm and had to return it because the radiator was way too big for my case / next to motherboard. It would also not fit in the front of my case without drilling out the HDD cage and front fan mounts (but then I would need to mount my SSDs somewhere else)

 

[lloydcars18]

@Guest2 yea my had 932 can hold upto a 360 but think a 240 would be enough.
