C8F Memory Overclocking

[Arrogath]

Hey guys, I've been trying to get my high end ram dialed in on my Crosshair VIII Formula for my 3950x build

I'm running the F4-3600C14Q-32GTZN kit, which is a 8GBx4 of decent quality B-die. From my testing I haven't been able to run it with 1T timings, and often tightening my secondary timings results in a strange post behavior. The board gets stuck on C4 or 15 during post, and the display doesn't say post error but rather says BIOS menu or something to that effect. Just curious if any other Crosshair VIII Hero or Formula owners are having similar issues with memory overclocking.

4 stick setups are bound to have more troubles, you'd better keep GDM enabled. Also raising voltage helps, so SOC to 1.1V and memory voltage to 1.45V

I've been finding that messing around with my SOC and related voltages tends to increase the frequency of these getting stuck in post. I'm also not a fan of GDM, I'd rather have my timings actually be what I'm trying to set them at and know if it's stable at those settings first. I'll look at turning it and power down mode back on after that. Thanks for the suggestions, I have been trying them.

 

I was just surprised how sensitive this motherboard seems to be during the memory initialization part of the boot cycle, my 2 stick 3200 cl 14 16GBx2 kit wouldn't clock worth a damn on it either. The impact is a much better motherboard performance-wise so far in my experience, it runs the 3200 kit at 3600 cl 16 tight subtimings 1T outperforming the better kit in throughput. Clears 8 passes of memtest too, pretty solid.
