Wie weet de optimale instellingen voor de AMD AM2 5000+, aangezien het DDR2 800 geheugen door de standaard multiplier (13x) wordt onderklokt op 742mhz.
Het schijnt dat je de CPU moet overklokken om het geheugen op 800mhz te krijgen.

"Remember that AMD processors don't have a front side bus, and the memory clock is derrived directly from the CPU clock. As a result of this, DDR2-800 is achieved by dividing the CPU clock by half of the internal clock multiplier. In the case of Athlon 64 FX-62 - which operates at 14.0 x 200MHz, or 2800MHz - the memory runs at CPU/7 in order to attain DDR2-800 speeds. This is all well and good, but problems are apparent when using odd-numbered internal clock multipliers.
As the chip uses the 13.0x multiplier out of the factory, it derrives its memory clock from the same CPU/7 divider that the Athlon 64 FX-62 uses. Anyone who's able to operate a calculator will realise that 2600/7 does not equal 800MHz. Instead, the memory on the Athlon 64 X2 5000+ runs at 373MHz, or DDR2-742.
In order to achieve DDR2-800 on AM2 processors with an odd-numbered CPU multiplier, you will either have to overclock the CPU in order to increase the memory bus, or you will be able to lower the multiplier and increase the internal clock frequency to surpass DDR2-800."
