No matter what I set in curve optimizer, cant reach more than 8650 pts in multicore (singlecore result is 641) - and I saw that some people can reach even 9k points - do you have any thoughts how to increase these points?
-
You can set your power limits to Motherboard, start the curve with - 15 for CCD1, and - 30 for CCD2. Usually this start point can be appropriate, then run stability test and keep undervolting CCD1 cores until the system turns unstable. Normal is that the best cores have the lower undervolt values.

Set your PBO power limit to the Motherboard one.
Set your PBO OC curve to negative 30 all cores.
Leave PBO Scalar to Auto.
Set your CPU voltage offset to -0.05v .
Set CB20 to High priority.
Do not run anything else, not even monitoring tools.
Run CB20 again and celebrate... then grow backward from there to reach stability.ID: gsr2244ID: gsql2ouI really wish everyone would stop recommending their CO configs to other people. Each CPU is different, -30 all core is not helpful, especially with a negative vcore offset on top of that, all this is going to do for most people is cause a shit load of idle crashes.
ID: gsqlp13Sorry Sir, is it so uncommon that a 5900X completes a CB20 test at PBO -30 and -0.05v voltage offset ? How am I supposed to know that it is uncommon ? Those were my two cents...

open task manager and give cinebench high priority then test, your scores should be higher
ID: gspv65zI already did it

Better cooling, those with very high numbers usually run custom water loops with thick radiators and a lot of fans on full speed(noisy), on "normal" high end tower coolers ~8500p is normal.
Ryzen is VERY temp dependent, even leaving windows open in the room for an hour gives better scores unless it's summer outside
A lot of curve optimizer and all voltages as low as Windows can boot also enhances scores, but it will be very unstable.
ID: gsqeo7vA cinebench run is so short that fan speeds make no difference. I can run my radiator fans at 0rpm or 2000rpm and get the same score.
ID: gsqmge2I just used a laser thermometer on my LF 280, and with ambient at 72.9F, rad starts at 76.4, peaks at 78.8. A minute after R23 ends, rad temps are 77.0 and falling slowly. I have my rad fans ramping down for 25 seconds after a CPU temp peak ramps them up.
ID: gspvxurIm cooling my 5900X with Arctic Liquid Freezer II 360 in push-pull config
ID: gsq6krjIntake? Mesh or open intake? Those are to prefer. Also check thermal paste, it should be even over the die and rather slight too much than too little. And check that Windows processes are behaving.

Did you log temps before/after? What were the results?
-
between IF clocks, memory, PBO, temps ... you can see a wildly different set of results.
For example my 5600x with stock settings EVEN with IF set to 1800 and 3600mhz memory, was showing sub average results. Turning one pbo entirely and setting 200mhz boost target suddenly bumped everything up into the top 5%.
ID: gsq6zo0Memory specifically has almost no effect on Cinebench.
ID: gsr33wuwhile true, it's still best to match it with the IF... it's all variables worth investing in

My 5900x: 1.28v 4.7ghz 9266pts
ID: gspwvggWhat tweaks have you made to your cpu to achieve such a good result?
ID: gspxjzxI don't use pbo, curve optimizer, etc. I just set fixed voltage and frequency. I know I'm possibly losing some performance in single thread, but I'm fine with that. What's your chip's frequency when running r20? I guess it's around ~4.5ghz.
-
I think the highest score with my 3900X has been in the neighborhood of ~7600+ points, so i think your current score is a very good one. I wouldn't sweat it...;)

I just got 8971, with an Arctic Liquid Freezer 280 II. I've taking Curve Optimizer as far as I can get, boost is 200 MHz, and I've overclocked the RAM.
You need to test various PPT TDC and EDC values. My best are around 170, 107,160.
Cooling is crucial. What are you using?

I'd probably recommend moving the opposite way, start at zero, test and keep working downward to -30 if possible.
