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 :

Code:
- Ai overclock tuner : manual
- CPU ratio setting : 7.5
- FSB frequency : 400
- FSB strap to North bridge : 400
- PCIE frequency : 100
- DRAM frequency : 800
- DRAM comand rate : 2T
- DRAM timing control : manual
- CAS latency : 5
- RAS to CAS delay : 5
- RAS precharge : 5
- RAS active time : 15
- RAS to RAS delay : auto
- Row refrsh cycle time : auto
- Write recovery time : auto
- Read to precharge time : auto
- Read to write delay (S/D) : auto
- Write to read delay (S) : auto
- Write to read delay (D) : auto
- Read to read delay (S) : auto
- Read to read dealy (D) : auto
- Write to write delay (S) : auto
- Write to wrtie delay (D) : auto
- DRAM Static read control : disabled
- Ai clock twister : lighter
+ Tansaction booster : manual
- Performance Level : 12
- CPU Voltage : 1.25v
- CPU PLL voltage : auto
- North bridge voltage : 1.25v
- DRAM voltage : 1.8v
- FSB termination voltage : auto

- CPU spread spectrum : disabled

Any help appreciated
performance level 12??
and i thought i was nuts....
thers no gain then on ure rams.. infact might be worse than stock

try this
fsb strap at 333
mem at 800mhz
pll at 1.6
nb at 1.35
ai clock twister at moderate/strong/very strong
transaction booster performance level at 8
fsb termination at 1.2v
gtl at 63 for both nb and cpu's
