im glad to hear that 👍 credit where credit is due, at the end of the day no vendors comes close to Dell's customer service standing behind their hardware.

you're right, i was referencing another scenario in my mind 😅

did you try manually changing PL1 limit?

some, it confirms storport.sys + iaStorVD.sys were interfering before (a clean fresh windows install after the BIOS change is highly recommended for perfect driver stack) did you uninstall the Intel Intel Rapid Storage / RST drivers and revert to using windows native drivers? In Device Manager > Storage controllers > uninstall any remaining Intel RST entries (right-click > uninstall device (select to also delete drivers), reboot). Let Windows use its standard NVMe driver. > Rerun LatencyMon - storport/iaStorVD spikes should drop significantly. ACPI.sys and kernel stuff here point to throttling. Disable CPU features like Intel SpeedStep or C-States in BIOS to keep things steady during benchmarks. also for your NVME controller, look for firmware update for it or if possible test with alternate drive just for validation purposes. as for NVIDIA involvement clean reinstall drivers with DDU tool, and check for power saving modes in NVIDIA Control Panel that might be interfering. Quick tweaks (do these anyway): Power plan - High Performance (disable all sleep/USB suspend in advanced settings, in particular look for and sleep features for the NVME drive or power saving nonsense). Update BIOS + chipset drivers straight from Dell's site for your your exact model (do not count on the drivers that shipped with the default system). NVIDIA Control Panel > Manage 3D Settings > Power management mode = Prefer maximum performance. Uninstall Dell SupportAssist / Optimizer if installed (known latency contributors). Rerun LatencyMon after each change to confirm drops.

absolutely agree! this is the main reason i didn't suggest more steps atm and was carefully building up to it from the logical starting point. (i did notice both the ACPI issue and NVIDIA potential)

@OneSunOne If your BIOS is set to RAID (Dell's default on many models), it ramps up storport.sys latency. Switching to AHCI mode often drops this dramatically and boosts consistency in I/O-heavy benchmarks. After that, uninstall Intel RST drivers and let Windows use its native NVMe ones. to do this change you must follow these steps to the T, if you missed F2 reboot and try again until you get it right (do not change this bios setting in any other order or you risk bricking your windows boot!) from windows admin command prompt issue perform the following in this order Enable Safe Mod: bcdedit /set {current} safeboot minimal shutdown /r /t 0 reboot, enter BIOS (Press F2 during post) Change SATA / Storage mode from RAID / RST → AHCI Save and exit BIOS Windows will now continue to boot into Safe Mode, once in Safe mode, from windows admin command prompt issue this command to Disable Safe Mode and boot back to Windows: bcdedit /deletevalue {current} safeboot shutdown /r /t 0 Windows will now boot cleanly in AHCI mode, if you still have the same issue afterwards report back.

both 7770 and the later 7780 were before they decided in all their wisdom to stack both dGpu and CPU on top of each other for the perfect "easy bake oven" effect.

taking you for a full circle 360 degree ride, wasting your time and money, just to leave you exactly where you started is not a solution im sorry, we call this a bunch of BS so other people can justify the poor job they are doing! do not close the ticket as resolved, you raised this ticket specifically for the WHEA errors and is the reason they sent the tech to replace your board with another faulty one in the first place, the errors did not go away, since you followed their protocol and issues still persists next step is a new system or refund your money. over here we have whats called the "Lemon Law" for the car industry, that should cover appliances now days not just cars. its a waste of your time they should now pay for since they feel its their to squander freely with... lets throw a tech visit to shut this case up, just shameful conduct across the board, you should escalate this to Dell corporate USA, and also inform the supervisor you are so he can have a good night sleep.

i believe these are sales executives directly tied to profit cuts from ASML very lucrative sales cake, they don't need ambassadors or high end specialty sales connections anymore, all and any possible market players simply come directly to them now. cutting these high paid executives with direct huge cuts off the ongoing sales parade is cruel but its just a textbook play for greedy corrupt corporations. (seen it first hand too many times)

OpenAI will go down in the history pages in the very near future, despite the arrogance displayed and passed as false confidence. similar historical events teach us important lessons if we choose to use the data when evaluating the current landscape, the good news are they will not disappear completely, case and point https://myspace.com NVIDIA is also about to be put in its place imho https://notebooktalk.net/topic/2901-the-madness-has-begun/page/2/#comment-64434

Thinking out loud, the AI buildup toward 2025 feels like it triggered a delayed realization at the top of the major CPU vendors like Intel, AMD, and ARM. For decades, Intel, AMD, ARM, and others built their market share through platform control. OEM relationships, ecosystem lock-in, and incremental architectural leverage made the CPU the anchor of the system. Then, almost overnight, they found themselves paying billions to accelerate someone else’s technology, reshaping entire systems around it, and effectively handing over slices of the very market they spent decades carving out. That is a reversal of logic. Instead of defending the platform, they subsidized the erosion of their own leverage. Value migrated away from the CPU and toward an external accelerator that began defining how systems are built, priced, and scaled. At some point, executives notice when they are funding their own displacement. What seems to be happening now is a quiet correction. Rather than continuing to pour capital into accelerating a smaller player’s dominance, money appears to be flowing back inward. Into their own roadmaps. Their own architectures. Their own standards and system-level control. This is not something you see announced in press releases. You see it in behavior, hesitation, and shifting priorities. You also see it in the market. Intel and AMD are no longer acting like companies resigned to becoming feeder components. At the same time, NVIDIA’s stock is not following the straight-line hype trajectory you would expect if total platform capture were inevitable. That divergence suggests reassessment behind the scenes, not universal buy-in. If the AI story were as simple as the headlines claim, capital flow would be one-directional. It is not. This does not mean NVIDIA goes away. It means the assumption that the entire industry will continue financing its expansion indefinitely is likely wrong. Platform owners eventually defend platforms. The AI boom did not just create demand. It exposed a power imbalance that incumbents tolerated for too long. What we are likely seeing now is the early phase of that imbalance being corrected quietly, deliberately, and before it becomes irreversible. The solution is simple, but overlooked: eliminate the silo. Unified, coherent memory allows CPUs and accelerators to operate on the same data without costly copies. Once that bottleneck is gone, the perceived GPU advantage evaporates. CPUs retain their performance, and accelerators return to their intended role: augmenting the platform, not defining it.

or simply a properly debloated, tweaked and tuned system.
