Is my RAM bad, or am I doing something wrong?
I bought 4000Mhz cl15 RAM assuming that I would be able to underclock it to 3733 and get great timings, but so far this hasn't been the case at all. (was this a wrong assumption?) First I tried to run the memory at the XMP profile settings of 4000 15 16 16 and I started getting errors at 2500% on RAM test. Shouldn't memory be guaranteed to run the XMP profile since it's advertised as that speed RAM? Then I tried lowering it to 3733 and couldn't get stable after many attempts at cl14 and going up from there.
Eventually trying the XMP profile settings but changing the speed from 4000 to 3733 and that wouldn't even run without errors.
I was doing some reading, and noticed it said in several places that RAM would probably start giving errors above 40c, and above 50c you would definitely be getting errors. I had noticed at least high 40s when I had been testing different speeds and thought maybe that was the problem why I oculdn't find any stability. So I reset to BIOS defaults which put the RAM at 1.2v and 2133(I think?)Mhz. And ran a RAM test at those speeds. I even took off the side and front panel of the case to allow more air flow. After 20 minutes the RAM was already at 43c. That seems hot according to what I'd read but I've never tried Ocing RAM, so don't really know how much of this is normal or not.
