Wait EveryOne!! Important thing to know about OCing with new BIOSes (DS3 F9 DS4 F7 DQ6 F8) and its official from my Friends in GB!! look for find out :
I have Patriot D9 that you can see in my rig When I flash to DS4 F7 I load optimized default + save and exit and first try 300x7 w/memory multiplier 3.33 but cant hit 1000MHz like before (F6-F5...) and wont boot at all (3 beeps) I try also 500x7 w/memory multiplier 2.0 but again cant boot I call my friends in GB and now I can hit 1040MHz!!! but how? way is :

First I set memory to 900MHz + save and exit it can boot next I set memory 930MHz + save and exit it can boot next I set memory 960MHz + save and exit it can boot next I set memory 975MHz + save and exit it can boot next I set memory 1000MHz it can boot next I set memory 1020MHz it can boot next I set memory 1040MHz it can boot!!

you should jump 10MHz-30MHz to reach pick!! its free to try .....

Now I can break my older record (FSB 500+1MHz) + 40MHz extra FSB means 540MHz and I should say DS4 F7 is best BIOS that I have so far
