noob help

hi guys hope this image has loaded , anyway although i was quite confident overclocking amd systems i am totally new to intel systems .
i know it is simpler to overclock in theory no hypertransport bus just fsb.
i can't get a handle on the memory timings though , so cpu is quad pumped so it is really running at 266 mhz ? yes.
and memory is dual channel so pc6400 should give me 400 mhz ? but with everything on stock i only get a windows vista rating off 5.1 for the memory and 5.9 for everything else .
the memory is set to 4,4,4,15 and 1t timings which i would have thought would be quite good so what gives . and it shows it running at fsb/dram ratio off 2/3 in cpuz . so the memory isn't running 1:1 at stock why is that ?
sorry for the noobish questions just trying to get my head round it

FSB is the Intel equivalent of hypertransport.

Looks like your mobo detected and automatically set your memory to its stock settings which is 400Mhz DDR800 PC6400. If it is to run 1:1 with the fsb the memory will run a lot slower at 266Mhz DDR533 PC4200.

Also 1T is a bit hard to run on DDR2, if it's stable at that then great but if it starts to bluescreen, freeze...etc then I'd first turn that to 2T.

1t timings seem stable ran the crappy vista memory checker twice no problems and was gaming online for over five hours with the ram at above settings with no problems . i am probably putting to much into that vista rating thing but 5.1 seems low ? what you guys getting ?

5.9 overall. I wouldn't worry about vista experience index as it means very little. Try running the mem benchmark tests in Sisoft Sandra or everest for some real figures.

although the board refuses to boot with 8 gb off memory no matter what i tried so it aint all roses crappy 680i chipset

You might want to try and raise the north bridge voltage and Dram voltage a little. I had to do that with just 4Gb let alone 8gb.

tried that steve258 spent all day yesterday mucking about with the voltages and tried two different bios's . the general feeling on dfi forums are some boards will and some won't , mine won't unfortunately . there seems quite a big difference between individual boards with this 680 chipset . which is a shame as on stock its as solid as a rock but that ain't what i bought it for unfortunately
