unfortunately I have an asus motherboard, in the post it states: * Memory Multipliers are invisible in the BIOS of ASUS motherboards. ASUS has chosen to use the resulting DRAM frequencies (BCLK x Memory Multipliers) instead.
Right now I have learned that for my BLCK Settings for the overclock I want I need to make my setting 171 (3.6) and the cpu multiplier would be 21, the default. What I do not understand now is the memory multiplier is invisible and I have to use the Dram frequencies... I have corsair xms 1600 but shows as 1333... I tried to do the provided math equation but cannot figure it out. I am really trying to learn but having difficulty, any help would be appreciated.
I don't know anything about that motherboard but it looks you have a muliplier of 21 with a bclk of 171 to get 3.57GHz. With that bclk 171 x 8 = 1368MHz or 171 x 10 = 1710MHz. Maybe that board doesn't like overclocking your RAM and defaults to 1333MHz. IF that is the case, your options for a bclk to get 1600MHz are 160 x 10 = 1600 MHz and 200 x 8 = 1600MHz. 160 x 21 = 3.2GHz or 200 x 18 = 3.6GHz Would be your cpu speed options.
I have i7 920 that will do 3.6GHz with all BIOS settings on auto with a bclk of 200 x 18 running prime 95 for 12 hours with no errors so yours should be able to handle a 200MHz bclk depending on your motherboard. You may need to increase qpi voltage to maintain stability. QPI max for that cpu is 1.35V. The default qpi speed is based on a bclk of 133MHz x 36 = 4.8GT/s. If you are going any higher than 3.6GHz then I suggest increasing the cpu voltage past the auto setting. I found that once I passed the 3.6GHz threshold my voltage requirements went up fast. For example, I needed 1.25V for 3.6GHz 1.3V for 3.8GHz and 1.4V for 4.0GHz. My temps hit 80degrees at 4GHz with a crappy antec 620 hydro cooler so I stopped at that speed.
