My system specs are in my sig. Will increasing the "external clock" to 200Mhz in bios affect my memory? or is the FSB independant from memory now?


Do you think it will run stable?

you would need to set the cpu fsb:memory ratio to like 5?:3 or something if u have it, otherwise it would try to run the memory at 200mhz.

will the external clock affect the CPU or the Memory more?

I'm using a thermaltake silent boost HSF.

right now the external clock is set to 133MHz instead of the 200.


what should the FSB/memory ratio be equal to with my current specs?

A 200MHz can affect both the CPU and RAM equaly, or you can set a CPU:RAM ratio. Seeing as how you only have PC2100, the highest you'll want to go, to get good timings, is ~133-140, around there, maybe more depending on the RAM. You could lower the timings and get better speed, your choice. Anyways, that aside, lets presume we'll only want to go in 133-140MHz range for the RAM. We'd want to set a ratio of about 5:3, like YOS said. Running this should give your CPU a 200MHz, while giving your RAM a 133MHz.
