P8Z68 Delux/Gen3 CPU-Z RipJaws F3-17000CL9D-8GBXM

[divermarz]

I have a new P8Z68 Deluxe/Gen3 (0301 BIOS), i5-2500K, and RipJaws F3-17000CL9D-8GBXM. I can easily configure the CMOS to correctly see the memory using manual or XMP profiles (X.M.P. DDR3-2133 9-11-10-28-2N-1.65V).
When I boot, at the POST I see the memory as DDR3-2133 (as expected). When I am in the operating system and launch CPUID CPU-Z V1.59, the "memory tab" shows up as 1066.9 MHz. All other configs show up correctly= 9-11-10-28, except the command which is 2T

The SPD tab (slot#2, #4) shows the memeory as PC3-12800 (800MHz), so the question is does CPU-Z incorrectly identify these sticks? and are they truly running at this speed

Thanks in advance

No they are reading correctly A) in the memory tab it shows the freq as 1066.9, but this is DDR (DOUBLE Data Rate) so the running freq is 2133.8, or spot on B) in the SPD tab the slot marked as MAX Bandwidth is actually showing the default boot up speed for the sticks, on your mobo it would be at 1600 which is PC3-12800.........so you are good!
