"ASUS P5Q Deluxe discussion".

[cstkl1]

Ok been on here lurking and trying to figure this thing out. My components consist of an E8400 stepping C0, P5Q Deluxe, and 2x2 Gig of Corsair Ram. I have been really struggling with this cpu for some time now, even with my old P35 Platinum P.O.S MSI board. The cpu is crap and very unstable @ anything ove 4 Ghz. Here are my current settings that are actually stable for quite some time now. Could use a little more help with the advanced settings such as NB GTL, FSB Termination Voltage, CPU GTL etc. I have tried some of the settings recommended here but as you will notice my voltages are quite a bit higher then most. I know I can lower them a bit if I can understand what these other settings actually do. thx

ok dude to find ure magic 4ghz...
since ure using e8400..

set everything above except
multiplier 9
bus 445
...
run linpack on vista 64 diagnostic mode max mem say around 30-50 times..
up ure vcore until u get this stable and then use back the template above with the vcore...
cheers...

well the template above with tRFC 25 works like a charm for 4x1gb kit.. so the major difference might be..
u may actually lower the vNB... and keep a high tRFC .

also a good practise after u completedthe multi 9 bus 445 and set the fsb to 533 above.. when ure bios boots.. keep pressing tab etc.. and enter windows mem diagnostic mode..
and run like 5 runs etc just to make sure ure NB/ ram are ok... before u boot into windows.. cause it would be pointless.
