In first case i wanna say hello to everybody cause this is my very first post in XtremeSystems, i've been reading alot from tons of threads but i didn't dare to write till now, i'm still too noob at overclocking, just started this february. I recently acquired an ASUS P5Q Pro after the death of a DFI DK X38-T2R (bad bios flash :\) ... and i paired it with an E8400 (batch Q810A055) that had been burn-in after several weeks of benchmark and Priming for a 24/7 stable setup. After purchasing it i wanted to test if the degradation myth (not the OC burn-in process) has happened and i obtained a pretty good results. According to the last version of RealTemp and CoreTemp my vid is 1.2250, here are some shots achieving "partial" stability though:
The first 3 tests were paired with 2x1GB Corsair XMS26400-C4DHX rated at 800Mhz 4-4-4-12 @ 2.1V

Though that, i finally updated the BIOS to 0901 and i was having problems with F@H cause it wasn't upping the voltage to 1.344 when needed so i had to finally set my CPU Voltage to 1.36250V to avoid sudden reboots.
Besides that, i'm having problems with 333Mhz and 400Mhz strap's as jVidia says since 0703 BIOS, i tried several methods as the tRFC to 55, PL to 10 and some voltages up but no luck at all, same with 500x8 who crashes within seconds at Prime Blend. Any advices to hit higher RAM speeds or should i stay with this last stable setup till a new official release of BIOS? 
Sorry for this long long post, i promise the following ones won't be that long ... i just wanted to be 100% sure of what i was doing before posting it as a "stable" configuration, hope to be helpful to someone too.
Best regards to everybody
