celebithil, в Диспетчере устройств правой мышой на

acpi компьютер на базе x86

Обновить драйвер. Вручную укажите многопроцессорное ядро.

Обновить драйвер. Вручную укажите многопроцессорное ядро. »

Даже когда убираю галочку "Только совместимые устройства" остаются только два варианта.

ACPI компьютер на базе x86
Компьютер с ACPI

[Angry Demon]

celebithil, обновите принудительно тем же драйвером ACPI компьютер на базе x86. Если не поможет, тогда попробуйте раскрыть Системные устройства и обновите тем же драйвером Microsoft ACPI-совместимую систему.

Процессоры в Диспетчере задач точно все видны?

[Petya V4sechkin]

Так ведь оно для одноядерных процов! Как его заменить на ntkrnlmp.exe? Диспетчер устройств -> Компьютер -> acpi компьютер на базе x86 хотя по идее должен быть многопроцессорный.

В Windows 7 x86 два варианта HAL:

• ACPIPIC - Компьютер с ACPI
• ACPIAPIC - ACPI компьютер на базе x86

Оба поддерживают многопроцессорность.
Так что "ядро" у вас правильное, проблема не в этом.

Что грузит? Судя по симптомам, DPC или Interrupts.
Обновите BIOS на сайте производителя материнской платы.

Почитайте
Периодически Hardware Interrupts (системные прерывания) начинает загружать процессор

Сделайте логи/отчеты при высокой загрузке DPC или Interrupts:

1. Kernrate
2. LatencyMon (перед использованием прочитайте документацию).
   • Для завершения мониторинга нажать кнопку Stop.
   • После зайти на все вкладки (Main, Stats, Processes и Drivers) и посмотреть результаты.
   • На вкладке Stats скопировать отчет целиком (в текстовом виде).
   • На вкладке Processes задать сортировку по столбцу Pagefaults.
   • На вкладке Drivers задать сортировку по ISR и DPC и выложить скриншоты.

Биос последний.
explorer.exe грузит до 20% при движениях мышки по рабочему столу. При загрузке системы с LiveCD (Windows 7 x86) такого не происходит.

____________________________________________________________________________________________________ _____
CONCLUSION
____________________________________________________________________________________________________ _____
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
LatencyMon has been analyzing your system for 0:01:34 (h:mm:ss) on all processors.

SYSTEM INFORMATION
____________________________________________________________________________________________________ _____
Computer name: CLOUD
OS version: Windows 7 Service Pack 1, 6.1, build: 7601 (x86)
Hardware: MS-7125, MICRO-STAR INTERNATIONAL CO., LTD
CPU: AuthenticAMD AMD Athlon(tm) 64 X2 Dual Core Processor 3800+
Logical processors: 2

CPU SPEED
____________________________________________________________________________________________________ _____
Reported CPU speed: 2010,0 MHz
Measured CPU speed: 3392,0 MHz (approx.)

Note: reported execution times may be calculated based on a fixed reported CPU speed. Disable variable speed settings like Intel Speed Step and AMD Cool N Quiet in the BIOS setup for more accurate results.


____________________________________________________________________________________________________ _____
MEASURED INTERRUPT TO USER PROCESS LATENCIES
____________________________________________________________________________________________________ _____
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

Highest measured interrupt to process latency (µs): 19406,097702
Average measured interrupt to process latency (µs): 14,968579

Highest measured interrupt to DPC latency (µs): 346,971473
Average measured interrupt to DPC latency (µs): 2,590765


____________________________________________________________________________________________________ _____
MEASURED SMI, IPI AND CPU STALLS
____________________________________________________________________________________________________ _____
The SMI, IPI and CPU stalls value represents the highest measured interval that a CPU did not respond while having its maskable interrupts disabled.

Highest measured SMI or CPU stall (µs) 5,587302


____________________________________________________________________________________________________ _____
REPORTED ISRs
____________________________________________________________________________________________________ _____
Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.

Highest ISR routine execution time (µs): 179,903483
Driver with highest ISR routine execution time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation

Highest reported total ISR routine time (%): 0,807726
Driver with highest ISR total time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation

Total time spent in ISRs (%) 1,062932

ISR count (execution time <250 µs): 72408
ISR count (execution time 250-500 µs): 0
ISR count (execution time 500-999 µs): 0
ISR count (execution time 1000-1999 µs): 0
ISR count (execution time 2000-3999 µs): 0
ISR count (execution time >=4000 µs): 0


____________________________________________________________________________________________________ _____
REPORTED DPCs
____________________________________________________________________________________________________ _____
DPC routines are part of the interrupt servicing dispatch mechanism and disable the possibility for a process to utilize the CPU while it is interrupted until the DPC has finished execution.

Highest DPC routine execution time (µs): 599,931343
Driver with highest DPC routine execution time: nvlddmkm.sys - NVIDIA Windows Kernel Mode Driver, Version 310.90 , NVIDIA Corporation

DPC count (execution time >=4000 µs): 0


____________________________________________________________________________________________________ _____
REPORTED HARD PAGEFAULTS
____________________________________________________________________________________________________ _____
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.

NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.

Process with highest pagefault count: chrome.exe

Total number of hard pagefaults 26
Hard pagefault count of hardest hit process: 21
Highest hard pagefault resolution time (µs): 13216,438806
Total time spent in hard pagefaults (%): 0,031245
