The very southwestern tip of Virginia. The beginning of last week was in the 10C range in the mornings when I get up.

If the cold boot issues are related to CPU temperatures of 20C and I'm starting the PC in the morning at a temperature of 15C that has sat turned off all night would that not make the CPU temperature below 20C on first boot causing the cold boot issue?

There's some saying about falsely associating a result with a stimulus, though I can't recall the exact wording...

But basically, since it was "cold" AND it didn't boot, they concluded that it didn't boot BECAUSE it was "cold", and disregarded all else.

The saying is that correlation is not causation. And this is true. Hence, further testing is needed. There is also: Where there is smoke there is fire. In other words, some correlations are more equal than others (with apologies to Animal Farm).

I know off topic but if anyone has been waiting for the Asrock x370 Taichi to come in stock, it is at newegg for the moment. I been waiting a month to get this board. Get in there quick if u want one I'd imagine they'll be gone soon.

Or the fact that I'm running water and my water temp is also 17°C obviously haha. At first boot my cpu temps are like 19°C, and it's not the cpu temp that matters but IMC/EC/RAM, its not the cpu failing it's training.

Considering all and i mean all we're changing is RAM strap what else could it be? Id love to have some enlighten me. Happens with case temps under 20°C but all day long when its above 20°C its fine. So its either temperature or time. You guys really think its losing its ram training over time? Come on now haha.

If there was no cold boot issues AT ALL there would be no LN2 jumper. Think about it.

So, easy workaround, leave your computer on 24 hours a day. If it is that cold, you should welcome the extra heat produced by the computer!

I'd be interested in whether someone who had installed 0003 and then 1107, and who is running a 3200 MHz RAM, reports this 20C problem or the negative -- that booting at lower than 20C is not an issue.

LN2 is outside the realm of this discussion. That's a temperature EXTREME. 19 degree = no boot / 20 degree = boot is nowhere near extreme.

And it's my understanding that AMD's initialization is to blame. It's due to a temporary low SOC voltage that can't be compensated by Asus. I'd imagine time is certainly a factor, and probably more so than temperature.

i've commented before about how i was getting insane high average vcore on the crosshair compared to my previous gaming 5 with XFR enabled... since updating to 1107 i've been getting EQUAL average vcore as my previous gaming 5. with one exception... my 1800x is able to maintain 3.7ghz on all cores under a stress test unlike my gaming 5 which dropped to 3.5ghz. so i guess some voodoo was done with 1107 in regards to voltage and XFR.... or the version of hwinfo i was using back then was buggy. either way i'm happy. its nice to have XFR enabled again smile.gif

temps are still higher of course but at least i'm seeing average vcore in the low 1.3v range from doing a ton of multi-tasking of light workloads. such as gimp with a few photos doing photo editing, firefox, foobar, steam, battle.net, and sc2 running in the background all at once. i'm using ryzen balance profile as well.

You're talking about me. My computer cold boots fine.
