If you have a gigabyte motherboard: Can you see an option in the BIOS called: "XMP high frequency support"?

Sorry for the late reply but I think I have found a definitive solution to these problems with XMP profiles: In the BIOS there is an option called "XMP high frequency support" at least on Aorus/Gigabyte motherboards, I don't know if other brands have a similar option. This setting has 4 options: Auto, Level 1, Level 2, Level 3. At first I always set it to "Auto" because I had no idea what it did, nor what the "Levels" meant. After some research I found a comment somewhere that said that probably the "Levels" are used to set the RAM frequency support as follows: Level 1 -> 3200MHz Level 2 -> 3400MHz Level 3 -> 3600MHz So I tested the configuration all in automatic, setting the XMP profile to 3200MHz, and using Level 1 in that option. And surprisingly, everything has worked like a charm ever since.... 3200MHz without any problems at boot or inside Windows. It seems the "Auto" setting does not work, you need to set it manually.

It seems this motherboard has issues with XMP profiles :sigh!: I can not make more testing right now because in past days the power supply of my old PC stop working, so I removed the power supply from the new PC (the one I refer in this post) and that new PC is in stand by until get a new power supply... Probably one of the most important parameter to help the memory work with XMP is the "command rate". Try to activate the XMP profile, then apply the voltage of 1.35V as you did, if the XMP is not setting it properly (I did not needed to increase any voltage in my system). Then try changing the command rate from 1T to 2T and test if the system can boot successfully...

This is an interesting question... For the power supplies with hybrid fan control or zero RPM mode, where the fan is stopped in low charge (like in this case) some manufacturers recommends to mount the power supply with the fan facing upwards, this way, when the fan is stopped the heat can be dissipated by natural convection trough the fan grille. Check in your manual if Corsair recommends something like this.

Good work, I Just have the same case since few days ago for my new system, i was planning something like this, but I never thought in laser cut wood. I was thinking in a transparent acrylic to see completely the frontal fans instead of the original metal plate...

The mainboard only have 4 LEDs to debug: VGA/CPU/RAM/BOOT and this LEDs remains on if some fails during post, but there are no code to see what exactly is happening. Is really odd the mainboard marks a VGA failure and not a RAM failure... ---------------------------------- I was reading several comments, videos and other info and it seems to be some issues with high speed memories in Ryzen platforms (this is my first Ryzen build). After reading some suggestions I decided to move manually the RAM timings in the BIOS, and finally I could get the system to boot successfully with the memory at 3200MHz. I don't know exactly what I did or which was the exact parameter that helped to boot successfully, I need to make some more testing and stability tests to see if all is working good now...

I just bought this case (iCUE 220t RGB airflow) in the past few days, and yes the space for the PSU is very tight. I am using a Seasonic focus GX-550 and firstly I needed to completely remove the HDD tray just to install the PSU, with the tray in position it was almost impossible to place the PSU (with cables attached) and the GX is only 140mm long... :brick: After installing th PSU and the HDD tray, there is very little space for the cables behind the power supply. I read this issues in other forums and sites before buying and that's why I decided to go for the shortest PSU I could found. I don't recommend using a power supply over 140 or 150mm long if you need to use the HDD tray, and of course with the tray positioned at the farthest position to maximize space. Maybe not impossible to fit a 180mm PSU (as stated in chassis specs) but you will have a lot of problems trying...

BIOS updated to latest (F50) and the same issue...

The motherboard came with F41 BIOS, I have not updated it because newer versions don't mention any memory support fix, but I will try to update it later today to see if this can help...

I just built a new system: B450 Aorus Pro WiFi Ryzen 5 3600 GTX 1660 Super Samsung 970 EVO Plus 250GB Vengeance RGB Pro DDR4 16 GB (2x8GB 3200MHz/CL16) part: CMW16GX4M2C3200C16 The issue is: If I activate the XMP profile in the BIOS the system simply won't boot, I only can boot successfully without XMP at 2133MHZ, the default setting. Every time I try to activate the XMP the system try to boot but there are several re-boots during the post and at the end I get a black screen (No video) and the motherboard mark in red the VGA led as a failure in VGA ??? Then I need to make a clear CMOS in order to enter BIOS or boot Windows again. The product page states this memory modules are compatible with AMD 400 series chipsets, so I don't know why the XMP profile does not work. Any advice on what to do now? Defective memory?
