New Z490 Extreme 4 Not posting

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   So just bought a new Asrock Z490 Extreme 4, an i7 10770k 32gb of g-skill Ripjaws. Updgraded from an Asrock Z270 i7 7700k  16gb RAM.   

Anyway unfortunately my build isn't posting. I have the 2nd light down on, on the Post Checker. My Post Status Checker light is showing just the one red light. Which according to the manual is DRAM 

I'll be honest, during my build at purchase i was looking down the list at compatible memory that i could buy from newegg  but couldn't find an exact match that was listed on their site, so i went with the the closest matching numbers i could find, which ended up being G-Skill Ripjaws  F4-3600C16D-32GVKC  DDR4-3600 16GBx2 CL16-19-19-39 1.35v

Is there anything i can do to get going ? I don't know where i can get 2x 16GB of compatible memory that's listed on the asrock site.

	So an update i guess. I tried using my old memory from my old build. G.SKILL TridentZ RGB Series 16GB (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 3200 (PC4 25600) Intel XMP 2.0 Desktop Memory Model F4-3200C16D-16GTZR I should of also mentioned in my original post that the memory sticks are installed in the DDR4_A2 and DDR4_B2 slots. This memory worked absolutely fine on my old Asrock Z270 Extreme 4 motherboard. But on my new Z490 board, i am still getting no post and the Post Checker light is showing the 2nd light, which is DRAM. Do i have a bad board or is this board just extremely particular to memory ? I know this memory is good. It was working absolutely fine on my older build. Gutted.

	Dear Asrock@72, Thank you for posting your query to the ASRock forum. We have checked the RAM, both memory modules are listed as Z490 Extreme4 supported modules. Here are some suggestions for you to try: 1. Please reinstall the CPU to the CPU socket, when the CPU is removed, please check the pins of the CPU socket. 2. Please install only one RAM to different slots. 3. Trying using the eraser to clean the gold finger of the memory modules. With thanks, ASRock TSD Edited by ASRock_TSD - 10 Sep 2020 at 12:21pm

	I did get it to post with just one stick of RAM. I tested both of my new sticks individually, and both worked when just individually plugged in. So i know both sticks of the RAM works. I also updated the BIOS to V1.20 hoping that it would help but it didn't. When i tried both sticks again after the BIOS update to V1.20 it once again failed to post with both sticks in the DDR4_A2 and DDR4_B2 slots. So i'm guessing a bad board. Also worth mentioning is the system seemed very unstable. After installing the Intel Inf driver that i pulled from the Asrock site. After installing it, as soon as i'd get to Windows, it would lose video display. Overall it just seemed very unstable.. it would also lose video after removing a flash drive, for no apparent reason. I'm back on my old asrock Z270 Extreme 4 and everything is 100% stable again. I will return this board to newegg, but worried if i get the same again, i'll only run into the same issues.

	Dear Asrock@72, Thanks for the feedback. After the INF driver is installed, the graphics card driver will also be installed automatically. While the graphics card driver is installed, the system will start tuning the graphics that cause the monitor to start to blink a few times. Once the graphics card is fully installed the system should work properly. Have you checked the monitor cable while installing the USB disk? Loose monitor cable can also cause the monitor blink. The above will be some ideas that might help. With thanks, ASRock TSD Edited by ASRock_TSD - 11 Sep 2020 at 2:23pm
