So Frustrated, Memory issues

[dmighty]

Im hoping someone can help
Here is the setup
AMD Phenom X3 720 with the gigabyte Ga-ma785GPM-US2H with 2*2GB OCZ
240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel running raid 10, 4 drives...was able to unlocked the fourth core with acc on auto and hybrid

Here is the problem
I cant get this memory to run at its peak, 1066 1:1
Ive been playing with all the options to no avail. At this very moment i have it running at 1:1 but DRAM freq is 245mhz. configuration is as follows
CPU Clock Ratio is @ 15X
CPU NB Freq @ 7X
Cpu Freq @245
Mem Clock @ 2.0x
HT Freq 1.6Ghz

i have the voltage up a bit on DDr2, nb volt, cpu nb vid and cpu volt.
the stock setup had the memory @ 800mhz. Memory timing is still at stock 5.5.5.15

what am i doing wrong? Any help is appreciated

Thanks

The closest you'll be able to get to the rated 1066MHz is 980MHz, using a 4.0x Memory Clock w/ the CPU frequency at 245MHz.

Is that due to the limitation of the FSB on the Proc? I assume it will not run stable at 250Mhz? I made that change and its running as you stated
490mhz dram freq..

Would 4*2 make a difference, though i would need to run 64 bit OS
Just curious. Still trying to understand the numerous MB options
HT Link Freq @ 1.6 ok?

Thanks for your help

If you increase the Memory Clock past 4.0x the effective DRAM frequency will exceed what the memory is capable of running at. By increasing the CPU frequency to 250MHz using the 4.0x multiplier, the effective DRAM frequency will be 1000MHz. That RAM should have no problem running well above the 1066MHz rated frequency and default timings of 5-5-5-15, but not as high as the next memory multiplier would put it.

Ok, I follow.. Would have have to increase the HT Link Freq if i continue to increase the cpu FSB? I currently have it at 1.8GHZ
Once i exceed 245FSB the system isnt stable. Board goes into safemode per say. more voltage needed or should i just be satisfied..LOL

Thanks Again
