Am I missing something?

I can't run my ram at 400mhz as it is supposed to by the website specs. My fsb is at 202 and the memory frequency is 202. If I increase the memory multiplier on my board the system fails the memory test and I have to clear the cmos. There must be something I don't understand about setting up the memory speeds. I ve tried bandwith benchmarking with sandra and the efficiency is 94 and 89. Can i do better? Maybe because the fsb is indicated at 202 and the memory freq is at 202, is it multiplied by 2 to achieve the final speed? Thanks in advance.

Your memory is running at 404 MHZ when the FSB is at 202.

So, when you increase the multiplier, you may be trying to run the memory a lot faster then you intend.

I thought that might be true, but i wasn't sure. Thanks for the info.

It is possible to set the memory to a 4:5 relationship in the bios and proceed with overclocking the CPU while maintaining the integrity of the memory chip. If you did that , then your memory would allow a maxium fsb of 250 while still staying within it's rated clock of 400. Check it out.

ratios help.. amd you would want 1-1 ratio but intels can do some good stuff with different ratios

Click to expand...

you would mean the 5:4 ratio

----------------------------------------
your RAM is DDR, Double Data Rate, which means that its speed is doubled...

400Mhz RAM = DDR200 or PC3200, if i were you, id keep it at 1:1 ratio, then pump up the FSB...
then when you cant go higher cuz of the memory... use the 5:4 one... just to get to know the limits...

good luck
