2700x safe temps / PBO / XFR + ram

[Bad_Company]

Hi guys. This post has two parts, first issue is ram oc and second is a question about cpu temps and pbo on/off.
system : 2700x + CHVII (latest bios : 1201) + krakenx62

ram : i run F4-3466C16D-32GTZR, i usually run them 3400 with slightly tighter timings or 3200 with even tighter , for some reason even with stock timings i cant get the system to post at 3466, is that normal ? ( btw i have never found a solid answer whether the kit is bdie or not ).

cpu : should i keep the pbo enabled or disabled ? While gaming ( bf1 for example ) i get temps up to 76 and clock almost stable at 4.2 - 4.2x, while with pbo on auto i get temps around 55-65 @ 4.175.

Either of those temps are fine. I'm surprised 3400 will boot on your ram its pretty hit or miss.

I think everything looks good you have going

What you're seeing is my same experience. The voltage and temps for OC aren't worth the few possible FPS. The only thing that showed real improvement was synthetic benchmarks.

Yep @drivingfast, marginal to none improvements at the cost of 10 °C. @Supahos Ram has improved with the recent bios versions, when i bought the system in june it wouldn't post at 3400. I was just trying to see how much more performance i can squeeze out of my 2700x without hitting very high °C.
