Asus P5E3 Premium Wi-fi-AP

I can't pass the 425FSB barrier. After a lot of tweaking i'm able to run hours of prime with 425fsb but more than this will result in instant prime errors

If your ram is not in question ,try to play with cpu clock skew : increase it at 500 ps and test again .

I had the same problem to pass the 400fsb until i found the right skews. The problem is that i don't know how to pick the best GTL's, nb skew and cpu skew I'm just trying lucky shots.

Atm i'm using GTL67/69, cpu 400ps, nb 200ps.
I can run prime 8h with no errors but sometimes i get 1 error after 8h30m. I tried to run that test and i can pass the test now and if i run it again i get an error dunno why. Anyway i think 8h is stable enough.
OCCT says stable...

After a lot of tests with this board , my conclusion is that the X48 chipset can't support a too high bandwidth with quadcore .

Try 5:8 ratio and relaxed timming instead of 1:2 ratio in order to decrease memory bandwith if you want be able to increase cpu frequency and get stable with prime95.
