I don't have my laptop with me right now. I can post tomorrow or the day after, but there's no secret. Undervolt the P-core, undervolt the E-core, undervolt and/or overclock the cache, ICCMax = Unlimited on both the iGPU and the CPU.

You must disable virtualization in the BIOS. Core isolation is disabled in Windows. The XTU version compatible with Core Ultra (Arrow Lake) is version 10xxx. The version you are trying to use, 7xxx, is compatible with older generation CPUs.

I use adaptive voltage. XTU is a heavier software than Throttlestop, so I recommend applying all settings and then closing the program. Your settings will remain until the system is turned off or restarted. If Throttlestop works better for you, use it! I've always used and preferred Throttlestop, but I switched to XTU with this system because of the extra adjustment possibilities. I don't have a liquid cooling system and I use an IETS GT600. I've tested Steel Nomad a little and haven't yet fine-tuned the system for this benchmark: https://www.3dmark.com/sn/12124446

Have you disabled Windows Core Isolation and virtualization features in the BIOS? Which version of XTU are you trying to use?

Yes, I use Afterburner. In the advanced BIOS tab, which is unlocked by checking the option in the manual settings of the Control Center, you adjust the memory and unlock undervolt protection. If you've never adjusted memory before, I recommend doing some research first. Generally, if the adjustment doesn't POST, the system itself reverts the changes and restarts Windows after a few minutes of trying to train the memory. If the system doesn't restart automatically, simply restore the factory settings: With the charger disconnected, press and hold Ctrl + F11 and click the power button for a few seconds. When the keyboard starts flashing, you can release Ctrl and F11. Wait a few minutes and the system will restart with the default settings.

Overclocked GPU! How much depends on the application... for example, in Time Spy I get +450MHz, while in Fire Strike the limit is +430MHz... For games I keep it at +400MHz to have a safe margin and not have to worry. VRAM always supports +3000MHz. I want to update to the XMG BIOS but I haven't done it yet. To get good results, just unlock the advanced BIOS menu through the Control Center and unlock the CPU undervolt and adjust the memory, in addition to the GPU overclock. I use XTU for CPU undervolt because with it you can adjust the P-cores and E-cores separately. On my CPU, -60mV on the P-cores is stable, limiting it to 5.2GHz, while on the E-cores at 4.6GHz I use -75mV, also completely stable. I have 2x32GB of SODIMM memory, therefore the modules are dual rank, more limited for adjustment. I achieved a stable 6400MT/s CL36-39-39-54 at 1.3V. I tried 6800MT/s at 1.35V but it didn't POST. I stopped there... With single-rank memory, 7200 or 7600MT/s at 1.35V should be easily achievable.

Memory: 5600MT/s CL46 => 6400MT/s CL36 (2x32gb DUAL RANK) NGU: 2,6GHz => 3,0GHz D2D: 2,1GHz => 3,1GHz Ring: 3,8GHz => 4,0GHz P-cores: 5,2GHz@-60mV or 5,1GHz@-65mV E-cores: 4,6GHz@-75mV or 4,7@-60mV or 4,8GHz@-50mV ICCMax: Unlimited 10-minute test: https://www.3dmark.com/spy/61810196 https://www.3dmark.com/fs/34303826

My Precision 7540 operates at low temperatures, with little noise, and has excellent battery life (more than 6 hours of light use without using the dGPU, even after more than 5 years). Even under full load, the i9-9980HK in stock configuration (4.2GHz on all cores simultaneously) never reaches 90°C (except in Prime95, which is a completely unrealistic load...). I use Kryosheet on the CPU, but with a PTM 7950 it should be similar. This is fundamental to achieving this level of performance, as is undervolting the CPU. I believe the cooling system of the 7530 is the same when comparing the same GPU class of each, so it's entirely possible to have a cool system with low noise in normal office use and good battery life. I doubt that the Zbook from the same year will achieve the same results... When I had an i7-9750H (similar to the i7-8750H) in that Precision, the temperatures, noise, and battery life were even better. The i7 undervolted and under full load, could stay at ~80°C all day with the fans at ~75% (~3900 rpm).

New score now with IETS GT600:

You're right, the different layout I saw was from the BIOS of the Neo 16 E23/E24. Your BIOS and options seem to be exactly the same as on my laptop. Including the exact same version 2.22.0059.

You probably changed parameters in the advanced BIOS that you shouldn't have, or changed them in the wrong way. From what I saw, I believe you changed the ICC Max to 0 (auto) while in my BIOS this value is at the maximum (2047). It seems you also changed P-core Power Density Throttle and Turbo Thermal Protection... According to the screenshots, that's what you did in addition to what I suggested. I can't tell if you changed anything else... I had only written to disable Undervolting Protection, Virtualization features, and Overclocking Lock. I suggest you don't change anything you don't understand. I believe your best option is to reset the BIOS to the original settings. Turn off the laptop, unplug the charger cable for a few seconds and plug it back in. Then press and hold Ctrl + Alt + F11 and then press the power button. Keep them all pressed for a few seconds and release them. The BIOS will enter a factory reset process. When the BIOS reverts to factory defaults, you'll be able to make the changes you want, knowing exactly what you're altering... It doesn't appear that the BIOS for the XMG Neo 16 E25 is installed. I believe the layout is completely different.

In the Control Center's Custom Performance tab, check the "Advanced CPU Settings" box (or similar) to unlock CPU settings in the BIOS. Close ThrottleStop and delete the settings file. It's an automatically created .ini file in the same folder as the icon. Disable Core Isolation in Windows. Restart the system and access the BIOS. There will be an "Advanced CPU" tab. Click on it. There, you can disable virtualization features, Overclocking Lock, and Undervolting Protection. Restart the system and you'll be ready to adjust the throttlestop!

Yes, I leave it on the custom profile with maximum performance and boost fans for benchmarks.

There's no OC on the CPU, only undervolting. I tried increasing the ratios using ThrottleStop, but although I can change it in the FIVR window, it doesn't seem to be applied. Both the P-cores and E-cores remain at their standard clock limit of 5.2GHz and 4.6GHz under full load. My undervolt is -60mV for the CPU Core and CPU P Cache and -30mV for the iGPU, with IccMax at maximum on all. I also unchecked the TVB option in FIVR so that the CPU doesn't reduce its clock speed due to the target temperature (I believe that with TVB enabled, the P-cores decrease by 100MHz starting at 70°C and another 100MHz when the temperature reaches 95°C).

Yes, yes, I can get similar numbers, but I want more... There is still thermal headroom, especially when using a water cooling solution or a cooling pad! My Control Panel is exactly the same! NVIDIA GeForce RTX 5080 (notebook) video card benchmark result - Intel Core Ultra 9 Processor 275HX,Avell STORM 580 Take a look at the single core from one of the screenshots.

I'm thinking of switching to the XMG BIOS because it has more adjustment options and because of the updates. It really works well, but I couldn't overclock the processor even after disabling Overclocking Lock in the advanced menu of the American Megatrends BIOS. Even increasing the Ratios in ThrottleStop or XTU, the CPU doesn't exceed the standard clock, even without temperature and power limitations... Undervolting, however, works perfectly. Thank you very much!

I have an Avell (Brazilian company) Storm 580 with an Ultra 9 275HX and an RTX 5080, which is exactly the same as the Medion Erazer Beast 16 with the American Megatrends BIOS. Did the BIOS update for the XMG Neo 16 go smoothly? Could you tell me about your experience? Furthermore, I can't access the XMG driver portal...

Be very careful when replacing thermal pads because if they are not the correct thickness you will have a big problem. If any pad is too thin, there will be no contact with the heatsink; if it is too thick, it can impair contact with other pads and the CPU and/or GPU. I recommend measuring the thickness of each original pad with a caliper and using soft pads. Or use good quality thermal putty and you shouldn't have any problems.

Simply download the VBIOS update firmware available in the driver list on the P7550 support page, extract its contents with 7zip, and click on the corresponding option (RTX 5000 or RTX 4000). The installation is automatic. https://www.dell.com/support/home/en-us/drivers/driversdetails?driverid=m1hhx&oscode=wt64a&productcode=precision-15-7550-laptop

My Precision is stored away; I've been using a newer laptop. Maybe this weekend...

I had an i7-9750H for four years, and it was completely stable at -125mV/-215mV for cache/core. With Speedshift = 0 (Windows power plan set to High Performance) I could maintain it at -135mV/-225mV. i7, i9, Xeon... I think it all depends on the silicon lottery. I agree that a 180W charger is sufficient for i7 (6-core) versions.

Not necessarily. Phase change pads better fill heat sink contact gaps.

Don't waste your time with Carbonaut because Kryosheet is much better. Your temperatures are fine, I wouldn't change anything if your CPU reaches max performance at 85°C at full load. On my Precision, Kryosheet provides up to ~15% more thermal headroom than the PTM 7950, but, as I mentioned earlier, it requires good contact between the heatsink and the CPU. I've tested Kryosheet on another laptop and didn't get good results due to uneven heatsink contact. You'll need to test it to find out. I like to drip a micro drop of thermal paste in 2 diagonals close to the CPU die so that the graphene sheet remains fixed. I forgot to mention, but I only use Kryosheet on the CPU. On the GPU, the phase change pad works great and is more than sufficient. Your CPU must be undervolted to achieve its full performance on this machine. On my old i7-9750H in Cinebench R23 to sustain 4.0GHz on all cores (maximum clock at full load): . without undervolt: ~100W at ~95°C and fans at 100% . with undervolt: ~60W at ~78°C and fans at ~75%

I tested almost everything available on the 7540's i9, including Gelid HeatPhase. In my tests, its performance falls short of the PTM 7950 or TG PhaseSheet, which are identical. The Gelid phase-change pad appears to be of lower quality, at least when I tested it. In any case, with an undervolt, your 7530 with Gelid HeatPhase should be able to deliver the full performance of the i7-8750H without difficulty. Before the i9-9980HK, my Precision originally came with an i7-9750H (very similar to the 8750H), and with a fully stable undervolt, it consumed a maximum of 60-61W to deliver its peak performance in Cinebench R23 (4.0GHz on all cores), and the temperature hovered around 80°C with the fans at ~75%. On my i9, Kryosheet can provide more thermal headroom than the PTM 7950, but this requires good heatsink contact. Otherwise, the phase change pad will be better... Always keep the air intake away from the tabletop with a laptop stand. It makes a big difference on these Precision laptops.
