Memory Divider Confusion....

Hi guys! I recently got some new parts and put together a setup with the following:

Intel C2D E8500
Gigabyte GA-X48-DS4
OCZ Reaper HPC 4GB (2x2GB ) PC2 8500

I've read a lot of posts here (like the awesome one from BlueAcolyte) but on my rig I am still confused. I overclocked my old P4C back in the day when there were a few less factors involved.

I'm currently just hitting a conservative 422x9.5 (4Ghz) @1688Mhz FSB, but the dividers are throwing me off. I know that my ram is DDR-1066, capable of 533 with a bit of headroom, but if I run 1:1 it would run at 422Mhz.

After this point I am a bit confused...if I try a memory divider such as 3.00, 3.33, 4.00, I don't seem to have a prayer of completing post even with increased voltages and relaxed timings. Furthermore, im even more confused because sometimes there are the same numbers with different letters like 2.66C and 2.66D which are supposed to be for different bus speeds but I'm just thrown off by that lol.

SiSoft gives my memory bandwidth around 7.7gb/s which looked pretty dismal compared to the top rated stuff 🙁

Is my memory pretty much running as it should? The highest I've seen it is 562Mhz at 3:4...but I don't even see people using that kind of divider these days?

Any help would be appreciated!




 
Gigabyte has an odd naming scheme in their BIOS for the memory divider.
2.00 is actually 1:1. I think it just tells the ram to run at 2.00 x the FSB. Try 2.5 or so?
