875P question

Does PAT disable itself above a certain fsb?

That may be rather motherboard manufacturer specific...I think the i865 mobo wont run them I believe after 1:1 ratio, but I am not aware of a cerain fsb shutoff in either the i865 or the i875...Some mobos may get flaky and it doesn't work well or the user has to turn setting off but that may be it....Also a lot of ram incompatabilities with current i865/i875 mobos may render them useless as well..

I can run CPC enabled and turbo now at 292fsb with cas 2.5 and turning them off changes my sandra scores so it must be doing something...The above mentioned is about all the sandra scores are worthy of...

DuvieI got a P4C800-E Deluxe and have been running at 304FSB with evrything pat, turbo, ht enabled (looser timings though) it dosen't feel as fast as 301FSB with 2-2-2-6 even 195FSB 2-2-2-5 feels much faster and it can't be the cas settings alone here..im starting to suspect that pat gets disabled after 195+..(i could be wrong though)

Well not a lot of ppl get that high on any mobo so you may have to tell us all!!!

There may be a point of diminishing returns with these NB chipsets that are being clocked 100mhz over there intended use...

I got a Golden MO step Costa Rica Im also running dual PSU's (nobrands) for stable voltage rails with all my devices connected!

1 PSU is dedicated to the mobo the other one for the devices It works great!
