I've tried over 100 different combinations in the BIOS to isolate every component individually and have determined my max BCLK, various CPU and Uncore speed/voltage combinations, etc., but this problem is stumping me.
My memory performs just fine at 1600 MHz as long as the BCLK is low. If I reach the same speed with a high BCLK and a lower multiplier, it's no longer stable.
133 BCLK * 12x multi = 1600 MHz (OK)
200 BCLK * 6x multi = 1200 MHz (OK)
200 BCLK * 8x multi = 1600 MHz (Unstable)
For the last 2, the resultant CPU and Uncore speeds are the same so they are out of the equation. This points to the RAM but it performs fine at the higher speed when the BCLK is lower and multi is higher.
I'm completely stumped and the manufacturer is claiming it's not the memory. Any ideas?
