Can't get full ram speeds, can't tell what's wrong

[BitLink]

So I recently upgraded everything except my cpu about 2 weeks ago, and of course that means debugging for a year or so.

I'll get right to the meat of the problem; my RAM isn't running at full speed and I don't know what's causing it. Why I'm asking here? Cause I have an ASUS ROG Crosshair VIII mobo, and it might be the issue...maybe. This is the full build https://pcpartpicker.com/list/pvm7kd

Now, the RAM is 4x16gb of DDR4 3600MHz, however in BIOS, it says my ram is at 2133MHz. I checked in Corsair iCue to double check, and it says 1065MHz! To see if it was just due to not being fully needed, I ran MHW, and there wasn't any change whatsoever.

So far, I 've tried using the BIOS to make it run the RAM at 3600, and it never makes it past post. It boots the BIOS back up in safe mode, and says it couldn't make it past post due to system instability. I tried increasing the voltage up to 1.4 watts, and that did nothing. I tried lowering the RAM tweaking to 3000MHz, and nothing. I tried using the smart tweaker, and it barely increased anything on the RAM, and still went into safe mode cause muh instability. I've also tried moving the RAM around, and nothing.

I'm going to contact Corsair and ask them about the Ram, and also try and see what else I can do, but I'm really tired of having things not work properly and want to fix this as fast as possible!

I just wanted to throw in on this conversation as I had an issue with getting my newly added Corsair Vengeance LPX 2 x 8GB rated for 3600MHz to work, heck even to get my rig to boot up. I previously the same EXACT model of RAM but it was rated 2666 with the BIOS version 5406 and had absolutely no issues setting it using the D.O.C.P. standard setting. When I got my 3600 RAM I tried to simply set it to 3600 and the FCLK to 1800 and good to go, right? Wrong. Not only would it not boot up but it refused to go into safe mode where I can get into the BIOS to make changes. The screen would just go black and I can hear my GPU fans running at 100% consistently but on the screen, nothing. I had to unseat the CMOS battery before it would let me get into the BIOS.

I know, I know. Get to the point on how I got it to work. 🙂 I placed the voltage to the recommended amount which is 1.35v and I started off with a modest OC to 2666 with FLCK to 1333 and boot up was successful. I then would incrementally in baby steps raise it up until I finally was able to successfully boot up with 3600. I then ran the Asus RealBench stress test for 30 minutes and passed with no crashes. My only explanation is that it doesn't like you to blast it right away, you have to ease it up slowly. Like a boiling frog. Mind you I have the lowest ROG board you can get (B-350).

Very helpful input, I have a ROG Crosshair VIII Extreme and having same issue, will give this a go.Â*
