Hi,
using an Asus P5B (BIOS 0806) motherboard I was able to set the FSB to 400MHz to run my E6300 at 2.8MHz.
However, with this setting the lowest manual memory clock available from the BIOS is DDR2-800, which my DDR2-667 can not take (system won't boot). On the other hand, if I keep the memory clock setting at "auto" then the BIOS sets the memory clock to DDR2-533, which is a waste considering I have DDR2-667 (but it runs stable).
If I am not overclocking, the BIOS automatically chooses DDR2-667 which is correct.
Now I wonder: how comes with FSB400 I can not select a lower than DDR2-800 clock manually if the BIOS can obviously deliver this clock (namely when set to automatic)?
And how comes the auto setting is not using the correct DDR2-667 clock, but DDR2-533 when setting the FSB to 400?
Has anybody experienced this before?
Cheers,
XOR
PS: I am using 2x 1024MB DDR2 Aeneon PC5400 CL 5, PC5400/667
