Hi
I am confused by the information in CPU-Z relating to memory on the memory tab and the SPD tab. Any clarification about what they mean would be greatly appreciated.
On the memory tab it indicates the dram frquency as 1064.1Mhz, which I think would indicate an actual speed of about 2100Mhz. I don't know what a FSB:DRAM of 3:32 means.
On the SPD tab under Max Bandwith it indicates a max bandwith of 2132Mhz. It also indicates XMP 2. At the same time in the lower section under timmings there are JEDEC 16,17,18 readings that give frequencies of 1066Mhz but under the heading of XMP-2998 the frequency is given as 1499Mhz.

My question in a nutshell is at what speed is my memory operating? I know it's not 1064Mhz but is it 2132Mhz or 1499Mhz x 2 = 2998Mhz? Or is it something else?

I have the following ram made up of two 8Gb sticks Corsair Vengeance LPX 16GB (2x 8GB) 3000MHz DDR4. In the BIOS I have and XMP 2 profile for memory. My motherboard is an Asrock AB350M.
