Asus A8N-SLI overclocking problems

My A8N-SLI has an incredibly frustrating problem. I have successfully set my A643200+ to run at 250FSB and 2.5GHz confirmed by the BIOS and by CPUZ and it is stable after 12 hours of simultaneous Prime95 torture test and CPUburn. I have set my memory to run at DDR500 speeds and it ran just fine as confirmed by CPUZ. What I cannot do is set my CPU and memory to run at those speeds together. Instead, whenever I get my memory to run at DDR500 the motherboard underclocks my CPU to 1.75GHz (yeah, that's arbitrary and weird) and whenever I overclock my CPU the BIOS sets my memory to run at DDR266 (and this is dynamic, not a fixed ratio, it adjusts the divider to make it run as near to DDR266 as it can no matter what FSB I set it too). The problem is that to overclock I have to set the JumperFree Configuration settings in the BIOS to manual and it automatically sets the DRAM Configuration settings in the CPU Configuration menu to auto and whenever I set the DRAM Configuration to manual it sets the JumperFree Configuration settings to auto and so I can't manually control both the CPU and the RAM frequencies and timings. I am running BIOS 1008. Anyone who has any similar experience or advice to offer, it'll be really appreciated.
 
my best overclocking results on my asus a8n-sli reluxe rev 1.0

running bios 1003.008beta and early winchester and bh5 was 2.90g with tha ram 230
with winchester 3000

lately ive been running a venice 3200 @ 2.75 with g-skill tccd @275 1 to 1 yea i am running t2.

there are lots of little thigs in the bios to check that could be causing the problem.

i would also add that i have had some problems after flashing the bios from windows --after a windows type bios flash i seem to end up with memory settings that won't stay set--they will let go--and cause computer crash and BSOD's

when flashing with award flash --this is not a problem anymore --si i allways use award flash when doing a bios update on any nf4mb.
