R rolacja New member Jan 12, 2014 #1 Greetings! I have a problem with BIOS settings. I cant set memory frequency above 2133Mhz. How can i unlock these settings ? Comp spec: Intel i5-2550k 3.4 (Sandy Bridge) MSI z77 MPOWER G.Skill 2x 8GB DDR3-2400 F3-2400C10D-8GTX

S SeekaX New member Jan 12, 2014 #3 for anything higher than 2133mhz your mainboard needs a 22nm cpu to work. you have a 32nm cpu.

Comp spec: Intel i5-2550k 3.4 (Sandy Bridge) MSI z77 MPOWER G.Skill 2x 8GB DDR3-2400 F3-2400C10D-8GTX Click to expand... Sandy Bridge CPU was the one whit very good memory controler on it, so it can be the CPU can't get pass that 2133 mhz. But have you tryed out X.M.P ? Just to see if that works, and if it dont do that. Then you know the CPU cant run with 2400 mhz memory. EDIT: After SeekaX hit the point more then me, your CPU is the hold up here.

R rolacja New member Jan 12, 2014 #5 When i set XMP, bios show DDR3 2400Mhz 10-12-12-31 1.65V, but memory settings show max 2133Mhz, and when i set frequency to AUTO I still get 2133Mhz So, max FSB to DRAM for 2550k is only 1:8, and nothing can push it more? FSB is 100Mhz, DRAM FSB is 133Mhz. Can i set FSB for 112Mhz, to get DRAM FSB 150Mhz and achieve 2400Mhz ?

There is no FSB on that CPU anymore because there is no northbridge. BCLK overclocking on 1155 and 1150 is pointless
