I have ddr400 ram but it is running at only 333 mhz. my motherboard manual says 400/533/800 system bus?

Question

how do i set my system bus to 800 so that my ram will operate at 400? its not in the bios. i have a pentium 4 3.06 ghz processor with intel 865G.

it is already in dual channel mode. but bios says system bus is running at 533 and ram at 400

Answer 1

865G chipset will run RAM at 400mhz if processor fsb is 800mhz. I think your processor has a default 533mhz fsb that is why RAM is defaulting at 333mhz setting.

Answer 2

The specifications of your motherboard for memory are as follows: memory memory style DDR SDRAM style of memory Slots 2 x 184 Pin DIMMs Supported RAM speeds 333 MHz • 266 MHz • 200 MHz Max Supported RAM 2 GB under memory style it states that it in common terms helps DDR memory. So the respond is that it does not help DDR2 memory.

Answer 3

In order to get the maximum speed from your RAM, you need to install it in matched pairs. In other words, two 512 MB sticks will be faster than one 1 gig stick, because it's a matched pair and allows dual-channel operation.

But not just any pair of 512s - they need to be a matched set, where both sticks are exactly the same.

Answer 4

overclock it in the bios?
