Staat de L2 cache in Win2k standaard uit? Ik heb een dual PPro met 256 kb cache per CPU. Heeft deze reg. bewerking zin voor mij?How can I enable the Level 2 Cache?
You can enable the Level 2 Cache with the follow registry key:
HKEY_LOCAL_MACHINE => SYSTEM => CurrentControlSet => Control => Session Manager => Memory Management
SecondLevelDataCache
for 256kB Level 2 Cache = 0
for 512kB Level 2 Cache = 200
for 1024kB Level 2 Cache = 400
NOTE: Level 2 (L2) CPU cache size can be sized this way, ONLY IF using earlier CPUs: Intel (and compatibles) 386, 486, Pentium, Pentium Pro, AMD K5/K6/K7, Cyrix, etc, with off-chip L2 cache SRAM memory (external, off the CPU die).
If using newer CPUs: Intel Pentium II/III/IV/Celeron/Xeon, AMD Athlon/Duron/Thunderbird, etc, with on-chip L2 cache SRAM memory (internal, on the CPU die), L2 cache size can NOT be altered!
