Hello all !

I actually need some for o/cing the Rampage Formula.

I'm nearly getting MAD about this mobo, for the following reason :

- I have random "DET RAM" at startup for every o/c i've tried

My specs :

- Rampage Formula (BIOS 308)
- Intel Q9300
- 2 x 1GB Crucial Ballistix PC8500 (BL12864AA.16FD5)
- Corsair HX 520 PSU
- 8800 GTS 512

No matter what parameters (even for softs o/cings) I set, as soon as its not stock settings, I can have a random DET RAM at startup (cold boot or reboot).

I've even tried the cpu level up and Super Mem Profile (which apply an auto o/c based on your specs), its all the same (random DET RAM).

The thing is that - @ stock FSB, with stock strap (here being respectively 333Mhz and 333) - , I can run the memory at 667/800/1066 using the appropriate dividers without any DET RAM (this means the memory's not faulty), but as soon as I raise up the FSB..............a DET RAM can occured at startup.

Example of an o/c profile that is 100% stable (hours of prime etc...) but that leads to random det ram at startup :
