Question about overclocking my athlon64 socket 939 3000

[nick1985]

ok, heres the deal. i set my memory to 133 so i could max out my CPU. i got my FSB to around 280 with a 3LTD. that was a little over 2.5Ghz so i decided that was high enough, time to get my RAM up to speed. (gig of mushkin 3500 level II). as soon as i set my memory to 166, it wont boot. i tried 166 with 2.5-3-3-10, with a voltage jump on the DIMMS, no luck. i tried 3-4-4-10. no luck. what can i do to get my memory to run a decent setting? 133 is just to slow, and 166 wont boot no matter what...am i doing something wrong?

If I'm not mistaken, assuming you have PC3200 memory, with memory set to "166" it will run at default speed when FSB=240. With memory set to 133, it will run at its default DDR400 with an FSB of 300. This means your memory would be overclocked quite a bit at 166/280. I guess you'll have to lower your FSB to around 250, or keep the 133 memory setting and trying to up the FSB even more towards 300.

Assuming you are running an HT of 3x, HTT @280 and a 9x multi, your memory is actually running at about 180Mhz at 133 setting. If you go to 166 the mem speed jumps to about 230Mhz.
