I have the Corsair Vengeance LED CMU32GX4M4C kit that I bought in 2017. I was running it in a rig that had a 7700K delidded and OC'd to 5.0GHz. I tried setting the XMP profile and running it at 3200MHz. It wouldn't run in that setup and I figured maybe it couldn't do the advertised speed because I was already pushing the system with the CPU OC. It did run fine at 3000MHz and for all intent and purposes that extra 200MHz wouldn't have been a game changer.
I am now using that same set of RAM in a backup PC that I just put together today. I set the 7700K back to stock speeds with everything set at auto and then set the XMP at 3200MHz. The voltage auto adjusted to 1.35V which should be more than enough for the RAM. It seemed to be working fine and then I got a weird issue with my screen resolution and Afterburner not even recognizing my GPU. Then I got a blue screen with a memory issue listed as the cause. I set it back to 3000MHz and everything is working fine again.
Did I just get a piss poor silicon lottery? Glad I went with G. Skill for my new build. It is running perfectly at 3600MHz with CL16 timings.
