You can also use MEMTEST86 7.4 from here
https://www.memtest86.com/
Either in legacy mode or UEFI mode and just do a test right there.
Then if you get errors, start finding which stick is bad.
But then you will know to RMA the RAM.

It's possible the CPU's IMC can be damaged but this is VERY RARE.
Even also possible the mainboard can be damaged, but this is also rare. Problems like this are painful and difficult to fix. Good luck.
Yeah man this sucks gonna start troubleshooting the ram tomorow. Memtest86 7.4 is better than hci memtest for this?

Unfortunately I set this as the very first thing I did when I started overclocking 3 weeks ago. It stays below 1.4 for my final setting of 1.360 so I am just going to live with it.

i would try them both, HCI should be more intensive

So you're able to set adaptive at a TARGET voltage, like manual?
Because I thought adaptive was 'automatic' voltage, based on a CPU's programmed VID, and you have to set offsets manually if the voltage the CPU is programmed to request isn't high enough for stability?

If that's the case, what's the difference between setting adaptive and manual?

Not sure how HCI is more intensive than UEFI memtest86.
Plus you can always run prime95 (AVX and FMA3 disabled) with Blend and a custom size set to 75% of your RAM, which also does the job quite well.

Memtest86 is to make sure you can actually load windows without destroying your OS and reformatting. If you pass memtest86, then you can at least get into windows safely.

Haven't tested much yet on this new board (Z370 Taichi) but seems like my 8700K requires less voltage..?

Been gaming a little at 5.3 ghz 1.375V, but I doubt that it will be stable, it can't be that good. tongue.gif

First priority is to get my memory stable..

Should I go for no AVX offset at this speed and voltage?

If that's the case, what's the difference between setting adaptive and manual?

As far as I am aware what adaptive does is sets a custom turbo voltage and when the cores aren't at turbo they follow the standard VID rules so it can down-volt all the way to like 0.63v or something like that. You can set offset in adaptive as well if you want to change the voltage across the entire VID range.

Stock frequencies ASUS Adaptive = default VID table scaling, but when you hit any of the turboboost multiplier bins you're on the adaptive VID + LLC + Offsets you've set. It's in the Asus manual even with Z170.

Isn't that what I said?
