hjälp snälla

hjälp med minne!

hej körde igång sisoft sandra för at kolla så allt stämde men det gjorde det inte det står såhär på memmory:

Warning 100 : Large memory sizes should be made of Registered/Buffered memory.
där längtst ner står det nåt vad är det och vad kan jag göra åt det?

för det känns som om det laggar lite

detta står me om jag trycker hjälp:

Tip T100 - Large memory systems (1GB or greater) should use Registered/Buffered memory, especially if more than 2 are installed on the same channel. This improves signal quality by reducing the load on the chipset channel. While these modules add an extra clock delay due to the on-board buffers (thus CL2 effectively becomes CL3), the stability will be worth it. Server chipsets with many memory slots generally require Registered memory.

Fix: If you plan on adding more memory, consider replacing the modules with Registered/Buffered modules. Do note that you cannot mix Unbuffered and Registered/Buffered modules on the same channel, but you may be able to if the chipset has multiple memory channels.

vad ska jag göra ?
