Thanks for the answers guys. I think we should start the thread with some of the things I've found so far.

I've read that crazypinoy was having trouble running his 4GB G. Skill memory up to 1066Mhz. Is that correct? Did you find something on the FSB strap?

My experience with memory on the P5E3. I have 4 sticks of 1 GB of Crucial Ballistix BL2KIT12864BA1608

Even if this memory is rated at 1600Mhz 8-8-8-24. Since I'm running 4 sticks I can't get past 1333Mhz 9-9-9-24.

Crucial explains that this memory starts by default at 1066Mhz 7-7-7-20, and crucial says it is like that to assure compatibility.

The funny situation with this memory, is that sometimes, the my rig won't POST at 1333MHZ, and I have to set it back to standard SPD of 1066Mhz. And no mater what I do it won't start at 1333MHz again. It's a selective werid thing happening with this mobo.

Yesterday, I again moved back to 1333Mhz and then it magically started...

Very weird.

I have to consider though that I'm running 4 sticks for this chipset, I don't think I can make them go 1600Mhz, so I'm trying to settle for a lower speed, but anyhow should be better than 1066MHz. This has happened to me with the BIOS up to 402 (No express gate:-)

I'll post mi rig here so you can see it.
