Realización De Overclocking/Underclocking 1.7.- REALIZACIÓN DE OVERCLOCKING/UNDERCLOCKING El objetivo de este apartado es analizar las consecuencias del overclocking y plasmarlo en una tabla. En la que consten las configuraciones realizadas y sus consecuencias (Tª, rendimiento, estabilidad, …): Lo más importante son vuestras conclusiones, que podéis incluir en la tabla y/o escribir junto a ella. Por ejemplo el efecto de opciones del BIOS‐Setup que afecten al overclocking como p. ej. Turbo Boost y EIST. Para ello se proponen los siguientes pasos: 1.7.1.- 1ER CAMBIO DE LA CONFIGURACIÓN DEL MICRO Observando el manual de la placa base anotar la configuración del BIOS que permite subir la frecuencia del micro lo mínimo posible respecto a su estado actual: Entrar en el setup del BIOS. Anotar la Tª de la CPU y del sistema: Verificar si se verán afectados otros elementos. Realizar la modificación, previa verificación del profesor. Ignacio Moreno Velasco. Tecnología Electrónica.

  • Analysis and Optimization of Dynamic Voltage and Frequency Scaling for AVX Workloads Using a Software-Based Reimplementation
    Analysis and Optimization of Dynamic Voltage and Frequency Scaling for AVX Workloads Using a Software-Based Reimplementation Bachelor’s Thesis submitted by cand. inform. Yussuf Khalil to the KIT Department of Informatics Reviewer: Prof. Dr. Frank Bellosa Second Reviewer: Prof. Dr. Wolfgang Karl Advisor: Mathias Gottschlag, M.Sc. May 03 – September 02, 2019 KIT – The Research University in the Helmholtz Association www.kit.edu I hereby declare that the work presented in this thesis is entirely my own and that I did not use any source or auxiliary means other than these referenced. This thesis was carried out in accordance with the Rules for Safeguarding Good Scientic Practice at Karlsruhe Institute of Technology (KIT). Karlsruhe, September 2, 2019 Abstract While using the Advanced Vector Extensions (AVX) on current Intel x86 pro- cessors allows for great performance improvements in programs that can be parallelized by using vectorization, many heterogeneous workloads that use both vector and scalar instructions expose degraded throughput when mak- ing use of AVX2 or AVX-512. This eect is caused by processor frequency reductions that are required to maintain system stability while executing AVX code. Due to the delays incurred by frequency switches, reduced clock speeds are attained for some additional time after the last demanding instruction has retired, causing code in scalar phases directly following AVX phases to be executed at a slower rate than theoretically possible. We present an analysis of the precise frequency switching behavior of an Intel Syklake (Server) CPU when AVX instructions are used. Based on the obtained results, we propose avxfreq, a software reimplementation of the AVX frequency selection mechanism.

  • Computer Service Technician- CST Competency Requirements
    Computer Service Technician- CST Competency Requirements This Competency listing serves to identify the major knowledge, skills, and training areas which the Computer Service Technician needs in order to perform the job of servicing the hardware and the systems software for personal computers (PCs). The present CST COMPETENCIES only address operating systems for Windows current version, plus three older. Included also are general common Linux and Apple competency information, as proprietary service contracts still keep most details specific to in-house service. The Competency is written so that it can be used as a course syllabus, or the study directed towards the education of individuals, who are expected to have basic computer hardware electronics knowledge and skills. Computer Service Technicians must be knowledgeable in the following technical areas: 1.0 SAFETY PROCEDURES / HANDLING / ENVIRONMENTAL AWARENESS 1.1 Explain the need for physical safety: 1.1.1 Lifting hardware 1.1.2 Electrical shock hazard 1.1.3 Fire hazard 1.1.4 Chemical hazard 1.2 Explain the purpose for Material Safety Data Sheets (MSDS) 1.3 Summarize work area safety and efficiency 1.4 Define first aid procedures 1.5 Describe potential hazards in both in-shop and in-home environments 1.6 Describe proper recycling and disposal procedures 2.0 COMPUTER ASSEMBLY AND DISASSEMBLY 2.1 List the tools required for removal and installation of all computer system components 2.2 Describe the proper removal and installation of a CPU 2.2.1 Describe proper use of Electrostatic Discharge

    Insist on DrMOS King of Power-saving Confidential Eric van Beurden / Feb 2009 /Page v1.0 1 EU MSI King of Power-saving What are the power-saving components and technologies from MSI? 1. DrMOS 2. APS 3. GreenPower design 4. Hi-c CAP Why should I care about power-saving? 1. Better earth (Think about it! You can be a hero saving it !) 2. Save $$ on the electricity bill 3. Cool running boards 4. Better overclocking Confidential Page 2 MSI King of Power-saving Is DrMOS the name of a MSI heatpipe? No! DrMOS is the cool secret below the heatpipe, not the heatpipe itself. Part of the heatpipe covers the PWM where the DrMOS chips are located. (PWM? That is technical stuff, right ? Now you really lost me ) Tell me, should I write DRMOS, Dr. MOS or Doctor Mos? The name comes from Driver MOSFET. There is only one correct way to write it; “DrMOS”. Confidential Page 3 MSI King of Power-saving So DrMOS is a chip below the heatpipe? Yes, DrMOS is the 2nd generation 3-in-1 integrated Driver MOSFET. It combines 3 PWM components in one. (Like triple core…) 1. Driver IC 2. Bottom-MOSFET 3. Top-MOSFET Confidential Page 4 MSI King of Power-saving Is MSI the first to use DrMOS on it’s products? DrMOS is an integrated MOSFET design proposed by Intel in 2004. The first to use a 1st generation Driver Mosfet on a 8-Phase was Asus Blitz Extreme. This 1st generation had some problems and disadvantages. These are all solved in the 2nd generation DrMOS which we use exclusive on MSI products.
