Enabling XMP casues flickering display in Windows 10

[juani]

Hi all!

When I enable the profile 1 of xmp I experience screen flickering on my display which may be due to the high voltage/wrong timing of the ram base on my research (https://rog.asus.com/forum/showthread.php?86320-Enable-XMP-cause-flickering-display-Windows-10).
i'm connecting via hdmi to the on board graphics card.

1) What should I change on the BIOS in order to enable xmp without the flickering issue?
2) I had to enable xmp to see the ram at 3600 MHz, otherwise it would be lower. This issue happened when I updated the BIOS to the latest version, it was doing fine with the BIOS from factory settings. Is there another way to tweak the BIOS so that the ram goes back to 3600 Mhz, without downgrading BIOS to factory settings?

I'm new to PC building and BIOS, so any help is very much appreciated!

Specs:
ROG STRIX Z590-E GAMING WIFI BIOS 1007
Intel i7-11700K
32gb ram (16x2) Crucial Ballistix 3600 MHz DDR4
Windows 10 Pro 10.0.19043 Build 19043
Intel graphics driver: Version 30.0.100.9864 8/20/2021

You don't mention the graphics card.

It may need this

Not huge fan of crucial memory. I stick with Corsiar Dominator or Gskill Trident Z.
First thing Id try is a boost in Vram to 1.4 then check the temps of the ram sticks with Hwinfo. I dont know how robust the heat sinks are. With the previous two mentioned 1.5V isnt an issue.
If that doesnt work then go into the ram timings and write down whats there for XMP then disable XMP and F10, save settings and reboot back into BIOS.
Then scroll down and and select 3600, Vram to 1.4 and replicate the primary timings at the top of the ram timings page and F10 and and reboot.

You can tweak more in tertiary timings for faster ram response later. Just to see if this has anything to do with your problem.


Using the CPU integrated graphics isnt the best of choice as you are putting more of a burden on the part of the CPU that does memory and everything else but the cores.
An increase in VCCSA and VCCIO may also help, in small increments like 100mV at a time. Increasing this will increase your CPU package temp but this may very well be your problem is this part of the chip is struggling to keep up with the ram and the integrated graphics.

If all this fails you may want to consider a discrete GPU AIC card. Just about anything will outperform the integrated and not tax your ram in CPU I/O functions. The integrated graphics are OK for stock settings with no OC of anything on a machine in which you intend to do noting more than productivity work. Start throwing an OC at anything and its a crap shoot and your graphics performance wont be very good no matter what you do. Docs, surfing etc is about all they are good for. You want to OC (XMP is above JDEC standards so its and OC) and you really need to get that load off of your uncore.

Hello,

Test memory stability with Karhu Ramtest or HCI Memtest Pro.

Increase VCCSA 20-30mv

Increase DRAM Voltage 20 to 30mv

Thanks for your quick replies!

Based on the first recommendation to stick with Corsair or Gskill, I decided to look at compatible memory for my mobo (https://rog.asus.com/motherboards/rog-strix/rog-strix-z590-e-gaming-wifi-model/helpdesk_qvl_memory) and turns out that the Crucial memory I had was not even listed.
I will return it and change it for a Corsair memory that is listed as compatible: CMW32GX4M2D3600C18. I hope the issue is automatically solved after I swap the memory, otherwise I will try everything you all suggested!

@BigJohnny: I will purchase a discrete GPU AIC card, waiting for prices to be reasonable again!
