  1. BCLK Frequency is 159.97MHz (verified in BIOS) CPU Core multipliers are all set at 27 (verified in BIOS) Other details from CPU-Z in the attached CPU image - they seem to accord with entries I could see in the BIOS. DRAM details I've included in the attached from CPU-Z which also seem to match the entries in the BIOS as far as I can see (BIOS n00b at large!) CPU-Z also seems to be reporting an odd MHz (it's certainly not 2133MHz halved). I removed the modules and checked their part numbers online - they're definitely 2133MHz modules. A few other numbers from CPU-Z.....

  2. Hello Fiery - many thanks. I've attached it as a text file (it was too long for the forum box)... pcidump.txt
  3. I have an i7-4930K overclocked to 4.33GHz. In AIDA64, the DDR3 speed is showing as 1280MHz (the system has 2133MHz installed). At first I thought it might just be a similar thing to CPU-Z where the speed shown must be doubled for dual-channel DDR3, but other example systems in the attached are listed with correct speeds. Is this a problem with my system that needs to be put right (I didn't do the overclock - the system builders did, so I'd need to contact them because I'm a bit of a tech chump), or a misreading or other oddity that I can ignore? Many thanks in advance.
