I’m hoping someone on here can help.
I have a HP Z440 workstation with an E5-1630v4 processor and 64gb of ecc ram (4x 8gb 2133 and 4x 8gb 2400, I know, “dON’t MIx rAM SpEEdS” but I’ll get to that in a second). The mobo chipset and Cpu can support up to 2400 of ecc ram with this cpu as per hp’s manual.
So, I know what you think I’m going to ask, why is my ram only showing 2133 total or why does it show 1086 in cpu-z? You’d be wrong, it’s showing 1866 in both windows task manager and the bios and 933 in cpu-z. I’ve tried the 4x 2400 and it shows 2400, I’ve tried the 2133 and it shows 2133, I’ve tried 4x 2400 and 2x 2133 and it shows 2133 but if I put the last 1 or 2 sticks of 2133 the configured speed drops to 1866. To get the 2133 speed I have to put 4x 2400 in the 4 slots to the right of the cpu (black/white/black/white) and 2x 2133 in slots furthest away from the cpu on the left (black/white).
Am I doing something wrong or just being really dumb here?
