tCL at 32 seems to be a no go even at 1300 and increased tRCD/tRP at 40. Yes, undervolt protection disabled and virtualization disabled in BIOS, core isolation appears to be disabled in windows. There's a large fluctuation in my Time Spy scores on a run to run basis from 25k to just over 26k. I'm using the watercooler and the laptop is raised on a stand. NGU at 30 and D2D at 31. Yeah on my other Neo with 13900HX undervolts gave pretty decent improvements.

How much extra voltage would you suggest? Tried at VDD 1275 and 1300. Edit: does the Control Centre override XTU? My undervolt appears to have nil effect.

New Timespy high score with RAM @ 6400MT/s - 26073 Timings: tCL : 34 tRCD/tRP : 38 tRAS : 54 tCWL : 34 tFAW : 16 tREFI : 40000 tRFC : 400 tRRD : 0 tRTP : 20 tWR : 72 tWTR : 0 tRFCpb : 300 tRFC2 : 400 tRFC4 : 300 tRRD_L : 8 tRRD_S : 4 tWTR_L : 24 tCCD_L : 12 tCCD_L_WR : 48 tWTR_S : 6 NMode : 2 VDD : 1225 VDDQ : 1175 VPP : 1800

How much voltage did you need to achieve this?

New TimeSpy high score for me. RAM at 7000MT/s: tCL : 36 tRCD/tRP : 42 tRAS : 72 tCWL : 34 tFAW : 24 tREFI : 30000 tRFC : 560 tRRD : 4 tRTP : 12 tWR : 48 tWTR : 14 tRFCpb : 300 tRFC2 : 400 tRFC4 : 300 tRRD_L : 12 tRRD_S : 6 tWTR_L : 24 tCCD_L : ? tCCD_L_WR : 64 tWTR_S : ? NMode : 2? VDD : 1250 VDDQ : 1250 VPP : 1825 The 2 timings with ? will automatically crash if changed. Any other suggestions for tightening timings/increasing voltage?

These are the settings I used with my old Neo 17 with I9-13900HX probably not ideal for Arrow Lake but worked. Still looking to get the voltages right for 7200MT/s but nothing is sticking and it restarts to 4800MT/s. Will keep upping the votages. Appears stable at 7000MT/s; VDD 1225, VDDQ 1175, & VPP 1800 with the standard 6400MT/s XMP timings.

No, 1350 is way too high to be stable. Presently running the XMP 6400 profile with Memory Voltage 1150, VDDQ 1225, & VPP 1825.

I have this kit and happy to run any test if you like?

I have just noticed that my 275hx limits to 160w no matter what I set PL1 and PL2 at. Any idea why? Edit: I am testing in XTU. Limits to 160w in the stress test but will pull up to 195w in XTU's benchmark. Edit2: cpu only pulls 60w in timespy cpu bench.

Interesting. I didn't know that the cpu power could be edited in the bios.

Is the 250W limit achievable with the Premamod BIOS and without the hardware shunt mod?

OK, so no undervolt and CC Performance profile set to Overboost/Overboost extreme I hit 17969 CPU score as a custom run. What profile are you using in CC?

So I "upgraded" from the Neo 17 E23 with I9-13900HX and RTX 4090 to the Neo 16 E25 with Ultra 9 275HX and RTX 5090. Timespy score from Neo 17 - 23644 Timespy score from Neo 16 - 24474 Detailed comparison. So it looks like the 5090 is ~11.6% more powerful than the 4090 but the Ultra 9 is 33% less powerful than the I9-13900HX. Advice, suggestions, help please.

Yeah, it was as simple as trying to run the wrong version. Edit: You have to undervolt core by core now?

Yup, got CPU ADV Perf Menu active.

I have Intel VMX Virtualization disabled, can't find Core Isolation in the BIOS. Trying to install XTU 7.14.2.69

I'm trying to install XTU but it's saying unsupported platform on install. I have secure boot disabled and unvolting enabled in the bios, have I missed something? Thanks.

Not first time. Left it on while I went out for food and returned to this. About to attempt a win 11 reinstall.

Got my Neo 16 (E25) today. It's stuck in a: It's been like that for 35 minutes. Any suggestions?

Awesome, thanks. That's the KF564S38IBK2-32 (16GB x2) DDR5-6400 CL38 262-Pin SODIMM Kit right?

@MiRaGe Could you sharing your BIOS settings for your RAM please? I'd really appreciate it.

What are your CPU and RAM settings to get this score? My CPU score is way behind yours - https://www.3dmark.com/spy/38287578

Hi, What RAM are you running and what settings are you using to get it to CL30? Thanks.

I'm running the PCspecialist variant of this laptop, 13900hx & 4090. Can anyone explain how to set up raid, I have two x 2tb 990 pro that I want to put in raid 0 for shits and giggles but can't work out how to. Thanks.

Hi Vandiekie, I flashed the BIOS from a USB drive. I hope that helps. MiSJAH
