Re: 3.8Ghz stable, but i want some 4 :D
Like Lsd says, get it booting using brute force then fine tune when you have a system that will start.
Set tRead to 11 also for now to completely eliminate that. Put the SMM to 2.00D. Right away you need to set Performance Enhance to standard, not turbo. Consider also setting tRFC to 78 for now and leaving it there along with tRead - 11. When you have the CPU running at 4GHz you can then move the RAM multi back up to give as close to 1333 as possible, then tighten timings again.
I also recommend setting manual timings right away. Looking at that picture of Memset, it's little wonder you get boot problems at higher FSB. Your RAM is rated to 9-9-9-20 at 1333MHz. Set it manually to 9-9-9-20 and you may find all your problems with not booting disappear.
For Vcore, turn on LLC and set 1.3625V. Set between 1.28 and 1.36V for CPU termination. You may want to test all these if there are still boot problems. PL can go straight up to 1.61V, also setting 1.59V for ICH I/O and 1.2V for ICH core helps. You can lower these later to see if you're stable with them at stock.
With MCH core, I'd personally start testing at 1.24V even though you're OCing the FSB. The P45 MCH IME doesn't need much voltage to OC well. 486 FSB came easily for me at 1.26V on a Q8200. Start at 1.24V and go to a max of 1.38V. Also, more isn't always better. There seems to be a certain "good value" for some, and any more/less fails.
