Hey all. I purchased a P4PDeluxe, 2.6c and 512 XMS4000PT mempory from newegg. I am putting it together this Friday. What do those timings mean? If I am going to run it at 3250 which is the sweet spot. What should I run those timings at? I am a little bit lost. Can you guys give me some ideas as to what it means and what I should run it at? The memory I bought is rated to run at 500mhz. Thanks.
 
........its the speed your ram runs........1:1=same speed as the fsb, 200fsb=200ddr..........5:4 = 5 divide by the fsb then 4 times that = your ddr speed, 200fsb = 160ddr......3:2 = 3 divided by the fsb then 2 times = your ddr speed, 200fsb = 133ddr.........
 
I think Thumper meant mhz, not ddr.

1:1 = 200mhz = ddr400
5:4 = 160mhz = ddr320 (doesn't go to ddr333)
3:2 = 133mhz = ddr266

Hi, You can try 5:4 for 3.2gig. Just try 1:1 and then 5.:4 dividers. Find your max. stabil point and than try to lower ram timings.

Regards

so let me get this str8. when u hit ur max point with vcore & fsb u should slow down ur memory timings? and then try raising ur fsb.

doesn't that create a bottleneck on the ram?
