How do I obtain a 1:1 ratio using ddr800 with an intel e8500??

You'd need to overclock your E8500 so that the FSB reached the ratio that matches the RAM:

DDR2 800/2 = 400

E8500 clock is 9.5 x 333 mhz = 3.2 ghz

So, if you want it to be 1:1, you need that FSB to reach 400, like the memory.

If you get it there, your new clock become 9.5 x 400 = 3.8 ghz.

That should be a moderate overclock and nothing extreme.

Yes, overclocking is worth the performance - IT'S FREE!

Good luck. Hope that's the info you need.

PS: Read the overclocking guide to help you out - it's got a lot of good info about what you need to do so you don't ruin anything in the system.

right, thank you very much! that is exactly what I wanted to know

good night gentlemen

Except that it may not be a good idea to OC your CPU straight to 3.8 w/out testing intermediate steps. More conservative approach is to set FSB at 400 and underclock the CPU to x8 (3.2 Ghz), then if that works raise the CPU multiplier in 0.5 steps. That way you you don't change the RAM and CPU demands at the same time so if/when it fails you'll know who's responsible.

why not just underclock your ram?
