Intel Core Ultra 9 285k 'Arrow Lake' Discussion/News ("15th gen") on LGA-1851

I tried the following:

NGU: 34
D2D: 34
RING: 40

E core bump to 5.0ghz
P core bump to 5.5ghz

All done via XTU and did not fiddle with any voltages.

Result in C23 = crash after couple min...
Do i need more volt on RING and NGU and SA? What is it called under Asorock Z890 Bios?
Also latency is around 86ns...tested via AIDA.

What should i do? Just want a bump to 5.5ghz on e core and 100hz extra on the p core...
Also want to reduce latency more this can be done with higher RING correct?
However i don't want to put to much increase in voltages the above settings are these a mild oc?

86ns seems a bit high, but could depend on the running BIOS / MC / ME.

I'd run something like the following first and then bring up the P/E cores, as that way, you know those settings are stable.

Max. CPU Cache Ratio [42]
NGU Ratio [35]
CPU D2D Ratio [38]

Ring DLVR Voltage [Manual Mode]
- CPU Ring Voltage Override [1.20000]
CPU System agent Voltage [Auto]
VNNAON 0.77v Voltage [Manual Mode]
- VNNAON Voltage Override [1.10000]

Then you can review the VF cures / vCore on the P/E cores.

I don't use XTU, so I can't advise on that.

Thanks for tbe reply i used this:

But the pic i shown caused crash in browsing but no crash in C23.

I use asrocks extreme profile and vnnaon is at 0.850v
Are the suggested volt increases on cpu cache aka ring and vnnaon not to agressive? Whats the max cpu cache i can go to at stock voltages 39 - 40?

Ring dlvr voltage = ring cpu cache correct? Instead of using 1.100v i use 1.200v correct? Oh my latency dropped from around 86ns - 88ns to around 74ns - 77ns just by enabling GEAR 2 instead of GEAR 4. Did a Memtest86 with GEAR 2 full pass just to make sure and it passed.

lastly not wanna do crazy oc just a reduction in latency and a mild bump on p and e cores some one said that my chip should do easy Pcore 5.6 and Ecore 4.9 easy on stock. Are the suggested volts increase save for long term?

Right now i am running:

- XMP 1 Gear 2 8800mhz
- PL1 - 300w
- PL2 - 318w
- CPU cache ratio: 40
- D2D: 32
- NGU: 32
- RING voltage override: 1.200
- NGU voltage override: 0.900

VNNAON i did not change yet since some one said to leave that alone valid advise?
Il do some testing if above is stable and report back here for further assistance if you guy's want of course just want a modest OC nothing fancy a latency of around 72ns - 73ns and a Pcore bump to 5.5/5.6ghz and Ecore bump to 4.9/5.0ghz and i am happy :)
As long as the OC doesn't impact my life expectancy of my cpu/mb it's all good.

They were some settings off my Apex, so using the OCF over the past few days, Asrock's naming for some voltages is different. The VnnAON runs at 0.77V, stock is used to help the D2D clocks, as normally you can get to 35-38 without touching, but putting it over 1.00v doesn't seem to make much difference, but it can help to stabilise a ratio of up to 40.

Those numbers don't look too bad, I'll have a play with the Asrock today and see where it ends up, and I'll post the config One thing I noticed which was rather odd the CKD mem sticks seem to throw errors a lot easier than my normal ones but not sure if that's them running OEM heatspeaders still.

Hey thanks for the reply. So a overclock.net member gave me these settings he is a well know overclocker. But his settings caused a crash to desktop when playing Elden Ring in just 30s tried 3 times and 3 times crash in about 30s anyway here are the settings he gave me:

XMP 1 profile= 8800mhz
GEAR 2
PL1-300w
PL2-318w
D2D = 32
NGU = 32
Ring ratio = 40
NGU voltage override = 0.900v
Ring voltage override = 1.200v


Also people told me that my cpu should easily handle at stock voltages: D2D-32, NGU-32, RING-40, Pcore 5.5/5.6ghz, Ecore 4.9ghz i did try this and no issues so far when gaming or browsing etc.

I wonder if i MUST use "Intel's Default" power plan or keep using "Asrock's Extreme profile" power plan when changing values?
Because under XTU just for information i see under "processor cache voltage" a value of 1.350v while his that he gave me is 1.200v = maybe cause of crash?
This is why i doubt that these changes should not be paired with "Asrock's Extreme profile"power plan since extreme profile has a CPU cache voltage of already 1.350v....

I changed the NGU + RING voltage override BACK to DEFAULT (but kept PL1 and PL2, D2D 32, NGU 32, RING 39 instead of 40) and no issues played Elden Ring for 2 hours without any issues. Played Cyber Punk 2077 for an hour also no issues at all
Still around 76ns to 77ns.

Interesting with the RAM you have 8400mhz
I tested my ram at XMP 1 8800mhz both at GEAR 2 and GEAR 4 with memtest86 and its a full pass success.
Would you recommend me to use that option to that gives me 9733mhz with my 8800mhz CUDIMM kit? there is a profile for it just enable it and that's it or do i need to change RAM voltage a bit higher that i do know its now i think 1.45v with 8800mhz.

So, Asrock seems to have a few quirks with how the boards run, or I am too used to Asus UEFI's now

To answer your questions:
  • Power plan, I would normally use Asrock's Extreme profile or Asus Extreme Profiles, but you need to test it to be honest. I'd run a simple test of the 2 profiles, reset the UEFI to defaults, run Intel's Default / Extreme on R23 for 10 mins and see how well the system handles it and then repeat with Asrock's Extreme profile
  • Cache / Ring voltage, I did notice yesterday when running a ratio of 42 it was running around 1.360. However, I'd need to test reducing it down to 1.200 / 1.250 would affect it.
  • In terms of the RAM, as a general rule of thumb anything over 9333/9400 will push you into G4 mode from G2. G2 is the IMC will run at half the frequency of the RAM and G4 will run at a quarter. It’s also often termed as the Gear setting. I’d personally keep with what you have as the higher you push it the more cooling that’s going to require. 8800 is a nice spot once tuned and stable. I’ll post a few tunes to see if that helps as a guide. On a side note tREFI settings are heat sensitive and as a rule of thumb: 32K is fine, 64K needs air cooling and 128K and 262K need to be kept under 45/40c respectively.
One thing I did notice, if the RAM isn't stable out of the box, you will have issues pushing all those variables

A Few Notes from playing around with the Asrock Z890 OCF yesterday, which you may find helpful:

CPU Cache Ratio aim for 40 to 42
NGU Max OC Ratio aim for up to 35
CPU D2D Ratio aim for up to 38

SA Voltage seems more important in AL than CPUs in the past and often runs higher
NGU - 0.92 to 0.95 - A quick way to tell if you have enough voltage is running the Aida 64 Cache & Memory benchmark and the writes will be low
VNNAON - 0.85 to 1.00 - Some CPUs will regress performance around 1.00 as it doesn't have the same tricks the Apex board does.

RAM Setup

VDD2 Voltage = CPU IMC - This is the CPU Memory Voltage
Vddq Voltage = TX - This is the signal quality to the RAM

VDD Voltage - RAM
VDDQ Voltage - RAM

RAM Settings - If you are running XMP these settings can be ignored

tCCD_L sets tRDRD_sg
tCCD_L_WR sets tWRWR_sg

UEFI Settings

OC Tweaker > Voltage Configuration > Voltage Mode > Stable Mode or Change to OC Mode
OC Tweaker > Voltage Configuration > System Agent Voltage > Auto or Fixed Mode > Set Voltage
OC Tweaker > Voltage Configuration > VNNAON Fixed Voltage > Type Voltage
OC Tweaker > Voltage Configuration > VDD2 Voltage > Auto or Type Voltage
OC Tweaker > Voltage Configuration > MRC Voltage Configuration > Vddq Voltage > Auto or Set Voltage
OC Tweaker > Voltage Configuration > DDR5 PMIC Configuration> VDD Voltage > Set Voltage
OC Tweaker > Voltage Configuration > DDR5 PMIC Configuration> VDD Voltage Range > Set OC Demand
OC Tweaker > Voltage Configuration > DDR5 PMIC Configuration> VDDQ Voltage > Set Voltage
OC Tweaker > Voltage Configuration > DDR5 PMIC Configuration> VDDq Voltage Range >Set OC Demand


OC Tweaker > CPU DLVR Configuration > Ring Voltage Mode > Change Adaptive to Override > Set Voltage
OC Tweaker > CPU DLVR Configuration > NGU Memory Fabric Voltage Mode > Change Adaptive to Override > Set Voltage

That's where I ended up yesterday with the OCF

Asrock's Extreme profile
CPU Cache Ratio 42
NGU Max OC Ratio 35
CPU D2D Ratio 38

NGU 0.95
VNNAON 0.85

Your mileage may vary on the voltage, as they are different from setup to setup, I am fairly limited on the Apex till the new Supercool heatsinks arrive, as they get too hot on OEM heatsinks, as I have built profiles out to 9333 to test once they arrive.

When I get a bit more spare time, I'll run a 1080p bench of Monster Hunter Wilds on stock, XMP, and manual setup.

Odd that it's only for the K processors. Would assume there would be a boost in sales if this was enabled for the Non-K parts also
In the previous gen the non-K CPUs had locked voltages, so maybe there's a technical reason they can't support it and OEMs would typically put them in PCs that aren't suitable for overclocking anyway.

Availability of non-K CPUs doesn't seem that great retail at either.
 
Has anyone updated their bios to support the new 200S Boost feature? I saw Asrock released the Taichi Lite version a few days ago so was tempted to give it a whirl.
 
I just wish we had more security in relation to the future of the socket.

Socket is dead - just a refresh coming with extra clock speeds. It'll never be anywhere equal to Zen5X3D in performance, yet alone Zen6 (also on AM5).

Intel will put all they have into Nova Lake (LGA-1954) on a brand new platform, due for release next year.

Well the thing with intel boost is....at least when you have the latest BIOS you can not change xmp frequencies ie say your xmp is unstable and try to loser freq...cant! Even when you NOT enable 200s! I tried with my G.skill 8800 cudimm to 8600 - 8400 - 8000 none of them will boot properly (it will boot twice then a corny message "cant boot successfully with current settings") then boots finally into windows and get a nice penalty on freq ie basic 4600mhz! G.skill told me my ram is not compatible with 200s.

Yet others enable 200s with their 8000+ kits and it auto downclock successfully but maybe they use regular udimm. So i switched to the second latest BIOS and lo and behold i can use xmp and lower frequency from 8800 to say 8400 and boots straight to windows no issue.

Also to anyone here pls hear me out:

Is all the time trying to fine tune my 8800 kit worth it for 1440p gaming in comparisson with plug and play 6400mhz? Dont get me wrong from my tests with the ram on stability i did not found errors on xmp 8800 as of yet. But Elden Ring and Cyberpunk crash after around 2 to 3 hours...with event viewer telling me id error 1000 and 0xc0000005 on both....then i altered VCCSA to 1.3v as maybe that can solve issue or disable c-state.... Im so tired with it....so yeah gaming wise is there a big difference in fps with 6400 vs 8800 at 1440p res?

It is hard to find benchmarks on that because the only ones I can find bench at 1080p and with a 4090 instead of a 5090, but my best guess is you're looking at around 5-10% at 1080p, but with a 5090 it could push that higher to 15% or so, depending on the game.

At 1440p, I'd think around 5% at 1440p with a 4090, perhaps 7-10% with a 5090, depending on the game and how CPU bottlenecked you are. At 4K I'd expect it to drop to around 3-5%. This is obviously backed by nothing, so take what you want.

My own opinion would be: you play/tweak this stuff for fun, so if it isn't fun, just set a stable setting and enjoy your games, because the difference is super unlikely to matter in something you'd actually perceive while playing.
