Escribo este mensaje porque tengo 6 Gbs de memoria ram modelo Kingston HyperX DDR2-800 PC2-6400 y según el post de la bios estan funcionando a 677 PC2-5300, mi placa base es una Asus P5B Deluxe y según el manual dice lo siguiente:
Due to chipset limitation, DDR2-800 with CL=4 will be downgraded to run at DDR2-667 by default setting. If you want to operate with lower latency, adjust the memory timing manually.
Some old-version DDR2-800/667 DIMMs, may not match Intel's On-Die-Termination (ODT) requirement and will automatically downgrade to run at DDR2-533. If this happens, contact your memory vendor to check the ODT value.
Mi pregunta es: como tengo que configurar el SPD de las memorias para hacerlas funcionar a su velocidad real?
He probado a cambiar manualmente en la opción jumperfree de la bios pero no me da la opcion de 800mhz, si no que pasa de 667 a 833.
Por otra parte en si configuro el spd manualmente tengo el siguiente menu:
Memory Remap Feature = [Enabled]
Configure DRAM Timing by SPD = [Disabled]
DRAM CAS# Latency = [5]
DRAM RAS# Precharge = [6 DRAM Clocks]
DRAM RAS# to CAS# Delay = [6 DRAM Clocks]
DRAM RAS# Activate to Precharge = [15 DRAM Clocks]
DRAM Write Recovery Time = [6 DRAM Clocks]
DRAM TRFC = [42 DRAM Clocks]
DRAM TRRD = [10]
RANK Write To Read Delay = [10]
Read To Precharge Delay = [10]
Write To Precharge Delay = [10]
Static Read Control = [Auto]
Initiate Graphic Adapter PEG/PCI
REG Port Configuration
REG Force x 1 = [Disabled]
He probado a poner las latencias en 5-5-5-15:
DRAM CAS# Latency = [5]
DRAM RAS# Precharge = [5 DRAM Clocks]
DRAM RAS# to CAS# Delay = [5 DRAM Clocks]
DRAM RAS# Activate to Precharge = [15 DRAM Clocks]
Pero aun asi sigue mostrando que funcionan a 667
