So how about 500Mhz+ FSB benching stable? Is that also impossible with this board?
If you're not afraid to destroy your board you can give it a try.

You are going to need 1.70+ Volt at FSB 500MHz to have it running with BIOS default MCH Read ODT 8T. You're going to have to keep the NB very cool and you're going to have to keep to room temperature very low. But that shouldn't be a problem if you take your system outdoor this time of the year.

Or you can try to tweak the MCH Read ODT with BAR_Edit to find better stability and lower volts.

I had tested PL7 + disabled vs PL8 + Enabled and found that the second gave me better results, so i have keep that.

Now with this bios ( i have put SoLoR's moded) should i go test the PL7 + Enabled (or Even PL6 +Disable)?
Or is the problem only hardware , since i remember that Rampage X48 is a handpicked X38 capable of running with tighter memory timings?
If you could boot with lower tRD with a BIOS release before BIOS 0902, but couldn't run it stable, than you should give it a try.
