Quick couple of overclocking questions

post #1 of 5
Thread Starter 
1. Why is it that, whenever I set my CPU's FSB higher than 295 MHz, my SATA drive stops being detected in BIOS?
2. I read NoAffinity's Intel Overclocking Guide & RAM 101, but I'm still kind of confused as to whether or not having RAM that's faster than your CPU (say, 200 MHz FSB CPU & DDR2-800 RAM) is a good thing, a bad thing, or just a waste.

Thanks for the help!

i can help w/ 1.

it has something to do w/ the chipset being oc'd w/ the cpu or sumthin like that. it gets unstable essentially and is np longer able to process the data for the sata controller. i don't think i'm spot on, but kinda close in my explanation...

OBTW, welcome to OCN.

On certain mobos the SATA ports near the CPU tend to act weird when OCing. Choose another port it should solve things.

It is good. RAM DDR800 Single channel gives a bandwidth of 6.4GB/s. FSB 200 for intel, being quad pumped (x4), gives the same 6.4GB/s. Having dual channel DDR800 gives a max of 12.8GB/s between the CPU and the ram, which is plenty even for a fsb=1600 (400x4).

This is slightly off-topic, but since an Intel CPU w/ a 200 MHz FSB has a bandwidth of 6.4 GB/s, wouldn't dual-channel DDR2-400 RAM have a bandwidth of 6.4 GB/s to match it? That's my current setup, and I want to make sure that running the RAM at DDR2-400 instead of it's max, DDR2-667, so that it's 1:1 with the CPU is going to get me the best performance.

Thanks for bearing my newbie-ish questions.

Alas, no matter which SATA port I use, my drive isn't detected when the CPU is OCd past 295 MHz.
