I got my Flex II yesterday and so far they are working great with LT X38 and current BIOS (03/14). I'm very happy with it.
DDR2-1168 was the max stable clock I could achieve:

Although the screen shows tRD 8 it's 7, only one phase is running at 8.
My CPU does not like FSB higher than 460, so I'm a bit limited on dividers.
Memory settings used:
This could get my new 24/7 setting:Quote:

// Edit
I have been able to reduce tRD to 6, so performance improved a bit.

FSB266 and 266/1066 divider or FSB333 and 333/1066 divider did not cause any issues to me. DDR2-1200 was no go with current BIOS, I could get it nearly stable at DDR2-1192. Do you have any news on the new BIOS files with PSC IC optimizations?
