how much you could pull the temps? i have serious issues below -100-120 ...

It was running full pot, but I had to heat up to -165ish because the IMC had a CBB. Booted up 3600 just fine at -100, couldn't get above 3200 at -165.

still a lot better than mine.

In 4 sessions my best was full pot with 2c enabled for max valid... not a single 5ghz 8/16 bench is done. seems the 1st mem freezes after 30min and I got bsod all over .. 

cbb is not an issue fortunately (x470 taichi )
