so i ended up exchanging my gaming 5 and 1800x for news ones, bought a new evga g3 750 to replace my current, and bought a completely different, new ram kit. gskill 2x8 16gb 3200mhz xas 14 flare x. i also bought a new case because hey, why not. a corsair air 740. haven't tried the ram at 3200mhz yet, but it seems like gskill is utilizing newer samsung chips that come stock with a higher jedec standard. i noticed its jedec standard is 2400 instead of the usual 2133mhz.
i wonder when gigabyte will be releasing a new bios update. f5d has been out for awhile now in all things considered with how fast they were shooting out updates. i wonder if they got delayed from amd releasing a new microcode update for the fma3 fix and more ram compatibility.
here is my aida64 cache & memory benchmark:
xmp profile worked out of the box and manual setting as well. though i did run into a hicup when i went to DISABLE xmp profile. i had disabled xmp profile to set everything back to default / auto / jedec standard and when i saved and exited the motherboard went into a reboot loop. i had to turn off the power supply to get it to stop. initially i was going to reset cmos but decided to see if it would boot after draining the power, and it did! but after that i still went ahead and cleared cmos for good measure. so i'm not sure if disabling xmp profile caused it or not, but i'm still going to give a warning about it.
oh and i'm also on f5d.
this is my exact gskill flare x kit: kit - F4-3200C14D-16GFX - https://www.gskill.com/en/product/f4-3200c14d-16gfx
here is a pic of aida64 at its default jedec standard:
huge improvement going to 3200. not just bandwidth but latency too.
