Eventually I had to up it to 1.34v to be able to play games without crashing. One of my friends mentioned that he saw a similar issue that ended up being caused by RAM timings, so I ran Prime95 "blend," which is supposed to heavily test RAM, and one of the workers spit out a rounding error. Dropped to 1.33v and it crashed right away. Testing small FFTs at 1.33 or 1.34 has no issues at all. So, does this seem like it's caused by my RAM? And if so...what should I be looking for? I honestly haven't overclocked consistently in like ten years so I'm effectively starting over.

E: I should note that all my RAM settings are completely stock, I haven't touched anything in the BIOS.

Its unlikely stock ram is causing BSOD. More than likely your overclock is not stable enough. try running prime 95 with no OC & stock ram. I bet you won't get error.

Are the vcores you have posted set in bios, are idle readings or load readings?

also please refer to Asus product page, I know Raja says 3000+ is not suited..

but on Asus product page it states 3400 Dram support

I already order Trident Z 3600 CL17 because I think at least if it can't OC much then it should still tighten timing easier than 3200.

My ripjaws 4 3000Mhz can boot on Z170-A at 3518Mhz but it can't get pass 3333Mhz with stability. I try every way but 3466Mhz is never pass Hyper PI 32M.

I bought Trident Z 3200 CL14. Will be overclocking them this weekend. One reviewer said they an go 3400 CL14 and 4000+ with relaxed timings so will be interesting to see what I can get them to.

Will be aiming at 3600 - 3800 speeds with some tight timings to get best possible minimal FPS in games. Probably 1.4 - 1.45v for 24/7 wink.gif

Can someone tell me why Voltage i'm setting in bios doesn't work properly? I have 6600k and Maximus VIII ranger, voltage set to 1.34 adaptive with LLC5 in bios.
Under Prime95 load however HWINFO shows 1.376 Vcore (MB reading) and 1.36 VID (CPU reading).
Shouldn't LLC5 keep it under the voltage i set in bios?

Read about any guide for HW/DC/BW/SL it explains the adaptive and Prime95 issues. CPUs negotiate voltage especially with adaptive, you are not setting it hard locked which is kind of almost impossible unless you disable about every power saving feature of the CPU and even lock the clock.

Thanks, that's good to hear. Prime95 at stock and at 4.6GHz/1.34v is totally stable. I just found it odd that I could run the x264 test at 1.29v indefinitely, without any issues, but Overwatch would constantly crash until I bumped it up to 1.34v. And Overwatch isn't exactly a taxing game. It makes me question whether the x264 stability test is actually useful. This is Windows 10, btw.

Settings in the BIOS. Load readings as measured via HWInfo are always a couple hundredths of a volt lower.

Not necessarily. I use LLC 4 for some settings, LLC3 when I want a little droop. Try LLC 4 first and see what you get.

EDIT: ah, Prime 95. It might behave a little differently.

Alright then. I tried testing 4.4GHZ @1.33V set in bios, it goes to 1.35VID / 1.344 Vcore (HWINFO64) in OCCT, RealBench,x264 and passes everything but in Prime95 blend test the core3 always fails after like 5minutes. I assume this isn't a stable OC then, and i should add more voltage? Ram is 2400mhz, VCCIO is set to 1.1V, rest is set to auto with LLC4.

When you test stability you should use static. Depending on the load adaptive can allow for more overshoot which is why many will say never stress test on adaptive voltage.
