Sorry if I missed your post, maybe things were hectic at the time.
I have the 2x1GB Kit, brand new kit came back from OCZ RMA in Netherlands.
So it's latest flex kit don't know about flex II version but I can now boot into vista on 466 FSB wheareas before couldn't do 460 FSB stable at all.
C strap can't boot at high MHz on my sys. Not even 1100Mhz.
I found that the memory dividers (eg, 2,00x, 2.40x, 2.50x, 2.66x, 3.00x, 3.20x, 3.33x and 4.00x) combined with the FSB determine performance.
Lowest memory divider x Highest FSB = Best Performance
Eg. 333MHz B strap has 2 memory dividers, 2.40x and 3.20x
To get 1100Mhz on B strap with a 2.40x divider, FSB will be 458Mhz
To get 1100Mhz on B strap with a 3.20x divider, FSB will be 345Mhz
Because of the higher FSB, the 2.40x divider gives much better performance at 1100Mhz
So the way I overclock my system is to find my CPU's FSB wall first and try all the straps to see what gives me the best performance, I don't really care about the Mhz of the RAM, it's the FSB that is the number 1 performance factor.
As for the tRFC setting these sticks work well at any Mhz with a value of 31.
vdimm is rated 2.1 - 2.3, I use 2.27 - 2.32, at 1150 B strap I use 2.2
B strap for me @ 466FSB (3.72Ghz) does 9,800 read, 8,500 write and 9,300 copy on everest. I'm very happy with that.![]()
Would love to see how these baby's do with a CPU capable of 500+ FSB!!!
Hope this helps a little.
