Verhoog je performance van je CPU

XP-Gebruikers: Verhoog je performance van je CPU

Lees zorgvuldig, en doe precies wat er staat.
-------------------------------------------------------------------------------- min over 512 ram MB moet beschikken

Voor mensen met Windows XP: Deze tip doet wonderen voor de performance van je geheugen.

Windows XP detecteert dikwijls je Level2 Cache verkeerd bij installatie en zet deze dus op 0 !!

Dat was bij mij ook het geval en nu ik die op de juiste waarde heb gezet (afhankelijk van je CPU) heb ik ca. 20% snelheidswinst bij het rarren, parren, rippen enz. enz.

Zeker eens nakijken dus iedereen ...
1. Start / Uitvoeren / Regedit

2. hkey_local_machine\system\currentcontrolset\contro l\session manager\memory management.

3. Bij subsleutel secondleveldatacache vul je als hex waarde 200 in voor een Level2 Cache van 512 Kb (voor de meeste gebruikers). Voor L2 cache van 1 Mb vul je 400 in, enz.

SUMMARY

<script type="text/javascript">loadTOCNode(1, 'summary');</script> This article discusses the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager \Memory Management\SecondLevelDataCache
REG_DWORD Range: Kilobytes 0, 1 -cache size Default: 0 (256K)
MORE INFORMATION

<script type="text/javascript">loadTOCNode(1, 'moreinformation');</script>WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

SecondLevelDataCache records the size of the processor cache, also known as the secondary or L2 cache. If the value of this entry is 0, the system attempts to retrieve the L2 cache size from the Hardware Abstraction Layer (HAL) for the platform. If it fails, it uses a default L2 cache size of 256 KB. If the value of this entry is not 0, it uses this value as the L2 cache size. This entry is designed as a secondary source of cache size information for computers on which the HAL cannot detect the L2 cache.

This is not related to the hardware; it is only useful for computers with direct-mapped L2 caches. Pentium II and later processors do not have direct- mapped L2 caches. SecondLevelDataCache can increase performance by approximately 2 percent in certain cases for older computers with ample memory (more than 64 MB) by scattering physical pages better in the address space so there are not so many L2 cache collisions. Setting SecondLevelDataCache to 256 KB rather than 2 MB (when the computer has a 2 MB L2 cache) would probably have about a 0.4 percent performance penalty.

Dus 20% snelheidswinst is wel wat overdreven !!!!

ok, dan maken we er 10 a 15 % van.
maar bij mij merk ik echt een goed verchil

 

[skinny]

hoe meet jij die verschillen want microsoft kun je slechts in bepaalde gevallen een winst hebben van 0.4% ???

 

[gabriel]

hey
wat Michael zegt is juist ...... waarom ???
als je xp zeer snel wil laten opstarten moet je deze laden in je ram geheugen
dit is in het kort wat Michael voorsteld ..... maar wat nergens vermeld staat (of zeer weinig ) dat je min over 512 ram MB moet beschikken ... dus zeer duidelijk minimum !!
