I am not changing the settings. Now Grnfinger have all the info to clock his x38 on my clocks and them we will be able to tell how much better the x38 is against P45 on the memory thingy.

Grnfinger,

It is all there. Just clock your system (CPU, FSB, MEM, MEM TIMINGS, ETC)respecting the numbers on my pic and then we will have an orange to orange compaison!

Thanks.
Well that Refresh Period is incorrect for that memory frequency. Asus bios don't always adjust it automatically properly or give manual adjustment. Refresh Period is 7.8uS, and tREF == ( tRFC[ns] * rows * banks ) / IO frequency

For 1GB dimms with 256Mbit memory chips, 4 banks , 16K rows and tRFC of 45 and DDR2-1066 which has IO frequency of 533.

tCK = 1000ns (1ms) / 533 (which is the bus clock of 1066) = 1.86ns
tRFC = 45 clocks = tCK * 45 clocks = 83.7ns.

so tREF for this would be:

( 83.7 * 16384 * 4 ) / 533 == 10291 clocks
Optimal Refresh period in clocks = closest value to 10291. Higher is always better.
