Runs fine at 22x, but the next multiplier is 24x, nothing in between! Not much of a performance gain at 2200, can't get it out of Auto timings at 2200 so CAS goes to 11-11-11-28. And at 2400, it won't boot.

Sounds like your OC settings are set to XMP or Auto, try setting to manual. Also set RAM timing to manual. To get finer memory speed setting, bump up the base clock a little at a time, probably not over 105 MHz or it creates problems with PCIe, etc. (105 x 22 = 2310 MHz RAM). I know everyone says to leave the bclk alone, but if it's stable after testing it's okay. My Asus P8Z77-V can only go to about 103 without stability issues, other boards may do much better. You also may have to increase various voltages to get it stable, so watch your temps.

I've left the base clock at 100. Need to jump back into BIOS, I recall it wasn't easy to get the XMP profile loaded and running the way it should be... even though it said it was CAS9, it was CAS11 in windows until I did something in BIOS, and I don't even know what I did.

Curious why the memory multipliers are what they are 21.33, 22 or 24 with no in between... is it the MB or IMC that controls that?

Just FYI, you cant compare performance to generic tests for other kits unless they also are running 4.7 GHZ cpu speed, as Intels CPU speed massively affects memory performance due to cache leveling. (Cache runs on same multiplier as the CPU)

Also a suggestion for another memory benchmark...

http://www.streambench.org/

Is the best memory tester, it is one of the only tests that is multi threaded so triple and quad channel setups will dominate and is actually what is used in programs like SiSodft Sandra
