CBR23: Multi: 32567 Single: 2188 MP Ratio: 14.89x

Details

dGPU mode.
Custom performance plan: from here.
UV: -100mv CPU -75mv P core E core.
Cooling Stand: Digifly BS1 on Max setting (3/3).
-# i uninstalled all the lenovo apps & a few microsoft ones but that's balanced by me having powertoys, steam, startallback, eartrumpet, and throttlestop in the background. Aside from those running in the tray, nothing else was running & nothing was open.

Temps

-# Temps felt pretty low for all of the 3DMark ones, looking at LLT made me think I had 40+C temps but apparently according to 3dmark my actual average was 60C gpu and 78C cpu.
-# Temps with cinebench multicore hit peak 93C multiple times, but cinebench singlecore was only 60C it seemed.

Extra (below was with no UV)

here's the detailed screenshots from the dGPU + custom mode run

#

seems to indeed be true that average temps were ~70C cpu ~60C gpu

#

I forgot to profile the cinebench runs with HWInfo but dont really feel like running more benchmarks, im very happy with this as is

#

i suppose i might run more benchmarks if i decide to increase the UV to -140mv or smth

#

guh thats a bit of work, ill try more aggressive uv another day #legion-7pro message

OCCT cpu+ram stability test (Should I have just been using CPU only test since i didnt do anything to the ram?)

👍 Wow, is it true that generally 7i pro is better to tweak than 9i (no pro)? I can barely push the gpu score to 22000 in timespy

unkempt cedar
#

not sure what u mean by tweaking tho, i think they should be similar?

#

You're probably getting thermal throttled, so u can either OC/UV, or u can buy a good laptop cooler (or also clean fans and change the thermal putty)

#

i think ppl justify the 9i for it's memory (ram) capability tho

#

Well to be clear, if it was me i would 10/10 times return and buy a 7i pro instead, but if that's not an option there are ways to justify it i think..

restive glade
#

return window passed already.

#

well, I guess I'll keep it and think something good out of it...cantbe at least I got it for a little bit less $$ because it is an openbox.. still 3k though.

#

also it is a bit weird that the multicore score in cinebench 2024 can reach 1875 but the single core is very poor, only like 102.

unkempt cedar
#

if it's only 102 that's not right, something's interfering and u need to re run it to get an accurate number

unkempt cedar
#

ask in #legion-9 or even 7pro

It seems 7pro has more power than 9i, the total power processor power target only goes up to 80w compared to 7pro's 110w; cross loading only to 60w instead of 109w....I suspect Lenovo knows 9i has a lame thermo system...

restive glade
#

the 2024 version? I think the 2023 version is better, some can reach 23k in stock settings.

restive glade
#

Mind sharing the tweaks? at least I can have a try...

restive glade
#

my machine obviously has a thermo problem. Maybe I should repaste it as well. CPU massively TT when running cinebench.

ahh

but i did have like youtube and firefox and a bunch of tabs open

#

On my system, somehow cinebench is extremely sensitive. With UV configuration that has no problem with timespy and is stable with prime5 for 12 hours, cinebench crashes almost immediately.

unkempt cedar
#

and there's also decreasing core and cache ratios

Hey. Have you ever be able to find the best overclock and undervolt settings for 4090 gpu i9 14th gen system, friend ?

unkempt cedar
naive cliff
unkempt cedar
#

Yep! Sorry for not going in detail earlier, i was on my phone and wanted to get home before double checking

unkempt cedar
# naive cliff Nice. Mind sharing settings of yours ?

in throttlestop (CPU settings):

(AC Performance profile)

  • High Performance ✔️
  • Speed Shift epp = 128 (default)
  • everything else can be left unchecked or on default

FIVR:

  • Undervolt simple:
    • CPU Core unchecked (see later)
    • P Cache: -99.6 mV ||(some people can do -100, but for me personally that causes instability so i stay at exactly 99)||
    • E Cache: -99.6 mV ||(same story as the P Cache, -100 doesnt work for me)||
    • System Agent, Intel GPU, iGPU Unslice: You can apply like -5 mV if you want but i personally don't since it becomes harder to tell what settings caused a crash
  • Undervolt V/F points:
    • In the V/F Point menu, check Use Core V/F Offsets ✔️ ||(and leave 'Unlock Adjustable Voltage' OFF in the main window)||
    • 800 MHz: -120mV
    • 1700~5400 MHz: -140mV
    • 5700 MHz: -120mV
  • Turbo Groups:
    • Group 0 & Group 1 ratios: 56
    • Group 2~7 ratios: 52
    • You're free to try increasing them, but that usually causes instability for very little gain. You actually may instead want to decrease them to 54 or so.
  • Cache Ratio:
    • Min / Max = 8 / 50 (default)
    • Sleep Defaults: ✔️ Cache Ratio ✔️ Voltage (helps with system stability
  • Miscellaneous:
    • Basically just defaults

MSI Afterburner (GPU Settings)

  • Memory Clock +700 MHz (another person recommended it as safe and easy, increasing or decreasing will probs have little effect on performance)
  • Curve Editor: +210 to all points then cut off at 825mV ⚠️
59FA32C7-537B-4F03-AED4-9C9647CBA457.png
#

⚠️ iirc this actually has crashed in some games, so using a lower oc like +195 would probably be recommended if you play a lot of games.

(Reminder: GPU clock only increases in multiples of 15. A setting like "+200" will internally be converted to +195)

naive cliff
#

Ahh, I understand

unkempt cedar
#

also i went through a little bit of trouble to set up the rivatuner display

#

in order to get GPU Voltage to show up in the OCD, you need to follow this guide:
https://rog-forum.asus.com/t5/rog-gaming-notebooks/guide-to-enable-quot-voltage-control-quot-in-msi-afterburner/td-p/564419

GUIDE to enable "voltage control" in MSI Afterburner

INTRODUCTION If you've installed MSI Afterburner before (usually on a notebook) you'd remember it didn't have GPU voltage control. There are unsupported desktop GPU models that require certain workarounds to have voltage control as well working in MSI Afterburner. So this isn't just limited to note...

naive cliff
#

Ahh, alrighty

#

Thx so much mate lookatthis

#

And sry for making you go through trouble to explain (I'm new to this stuff)

#

I'll try these settings if I get into a trouble with lenovo vantage oc

unkempt cedar
#

lenovo vantage oc/uv?

#

isn't it barely anything?

naive cliff
#

Well, I really don't know since I can't test it because my laptop is not with me. I'm in university rn xd

naive cliff
#

I was thinking of overclocking gpu with medium level
-gpu core +125 mhz
-gpu memory +250 mhz
-performance mode

Hmm it's been a whole year since I last used this benchmark post

#

maybe I should make a new one?

Turbo Groups:

  • Ratios capped to 52
    CPU Core:
  • -140.6mV
  • IccMax 240.0A (default)
    P Cache:
  • -140.6mV
  • IccMax 240.0A (to match the Core)
    E Cache:
  • -75.2mV

Cache Ratio

  • 8 to 50 (default)
  • Sleep Defaults: ✅ Cache Ratio, ✅ Voltage
    -# Note I have memory ddr 2794 for some reason, and microcode patch 12E which comes with the 27W bios patch

Misc:

  • AVX Offset: don't bother messing with it, nobody else seems to ❌
  • Ring Down Bin is good ✅
  • Thermal Velocity Boost bad for stability ❌
  • V-Max Stress is bad (shouldn't make a difference, but just in case) ❌
  • Overclock: also leave off ❌

this is because the Digifly BS2 Pro is absolutely goated

unkempt cedar
#

Core -135.7mV, 511.75A; P Cache (aka Ring) -125.0mV, 511.75A; System Agent -1.0mV, 511.75A; E Cache -70.3mV
Turbo Groups capped 52x
Per Core -> E Cores lowered from 41 to 39

#

PL4 set to 0, PL1 set to 140 (Clamp), PL2 set to 190, time limit 160 and sync mmio on

#

TVB and V-MAX off, Ring Down Bin on

#

now what do i want to experiment with to push more performance...

#

im going to start by seeing if lowering E Cores even more has any effect

#

(Also, I had PROCHOT on 98 C)

unkempt cedar
#

im going to increase the SA by -1mV, the Core by -1mV (-136), and the P Cache to -130.9

#

E cache ig ill leave at -70 just incase

#

DAMN

#

it got to pass 25 right at two seconds left but the outcome was only 32,223

#

next up increase CPU E cache to -75

#

ill do this next if im still not seeing any progress

unkempt cedar
#

32,140 points

#

TwT my small changes aint doing nothin

#

lets try the quick & dirty instead

unkempt cedar
unkempt cedar
#

32 254

unkempt cedar
#

32 256, 32 152....

unkempt cedar
#

Only 1859 single core pts

#

17.94

#

34 134

#

set pl4 to 9999 got 34074, 34061,

#

lowering E cores to 36 or 37 had a negative effect, no more 34k

#

back up to 38x and i got a 34,113, 34,128
