I have an Asus A8N32SLI with a 3800X2 E6 stepping processor in it. I have the FSB set at 250, NB to CPU 4x, NB to SB 5X, I have all settings on manual except for the ram delay which is on auto. Right now it is at a 300 delay which it was at before. I just changed my ram from OCZ 400512ELPE to OCZ5002048EBPE-K.

The problem I am having is before I could run my system at 252 FSB with 10x mulitplier and ram set at 166mhz setting for a ram speed of 210. Now I have my ram set at the 200mhz setting because of running 500mhz ram. The issue I am having is I no longer can run at 252 mhz fsb. I can an only run at 250 mhz fsb. If I try booting at anything higher the comp locks up and I have to flip the power switch on the power supply off and then back on. It reboots and says bad overclock.

I know I am now running the memory speed into my processor at 500 MHZ instead of the designed 400 MHZ. But I have seen people with 533MHZ in the same system and I am sure they are running a fsb frequency close to that or why that high of memory. Does anyone have any idea why I would be getting capped at the exactly 500MHZ?
 
you set the memory ratio to ddr500 with the htt at 250mhz? it's not a cpu limit with the memory at slower speeds?
 
Hi,I know this is a bit off topic but i have a question. Once cpu ocing is complete and you have overclocked your memory do you restore cpu oc frequences. I ask because once Cpu ocing is complete you are always told to futher return to the HTT bus and lower it as you did when you first began ocing the cpu, so you can find the max for your memory. Inturn since i lowered it a gain to finf my mak mem frequency do I rais it back up to the new oc value I gained before i began ocing the memory. If so wont it then raise the memory frequency from what I have already found to be its hightest, and if not what happens to my cpu... I would have oced it just to lower it.

Thanks to all those who can answer this question, so to send me on my overclocking way.

just do whatever it takes to get the maximum cpu clock and get the ram as close to it's max as you can without sacrificing cpu speed ;)
