Thanks, I like 01/06 as previous bios my G.Skill PC3-12800HZ D9JNM and Samsung HCF0 modules didn't boot properly (HCF0) and weren't as stable (D9JNM). 01/06 allows my Samsung HCF0 to shine - see below

I haven't investigated the relationship between each mem multiplier in detail yet - but yes higher mem multi max ram clocking harder i.e. between 8x versus 10x versus 14x but look carefully at your subtimings on AUTO at each mem multi and at each mem frequency you test particular tWTR which on AUTO or even when set will have different values at different mem multis as well as at different mem frequencies if you check using cpu tweaker and/or memset latest versions


Max BCLK with 10x Memory Multiplier
- limited by memory max overclock frequency


Now to try max Bclk frequency with 10x memory multiplier - ultimately will be limited by how far my memory modules can overclock

Interesting that up to DDR3-2263Mhz system registered 3x1GB Samsung HCF0 unmatched modules as triple channel, but when I hit DDR3-2298Mhz, windows reported dual channel instead of triple channel ?? Not enough volts somewhere or maybe my 1GB G.Skill PC3-12800HZ module can't keep up with my Corsair DDR3-2133C9DF modules ??
