Question ASUS PRIME B550-PLUS Motherboard w/Ryzen 7 5800x

[dengle1962]

This motherboard does not have the Flashback Bios button on some of the other ASUS motherboards. Is there any other way to flash the BIOS up to enable the motherboard/CPU to post? Every video I have seen has that *#$@$ button by mine does not. Just learned ASUS has an RMA program but this can take about 10 days or so. Any other recommendations?

I would think that the motherboard would natively support the 5800X without a BIOS update. What other components do you have installed in this system (make/model of each)?

You must have a stand alone (a.k.a. dedicated) GPU installed with that CPU as it lacks an integrated video controller, in spite of the ports attached to the motherboard.

Thanks. I tried it with the GPU I have (GeForce RTX2060S). I removed the memory and tried just one slot and then none. I finally decided to take to a shop to have them update the BIOS so I can get it to post. Frustrating. I also learned about this.

A bit frustrating for me as I have built many over the years and this should have come with the BIOS necessary to post with the newer processors!

And was the shop successful?

And was the shop successful?

Took it in this afternoon. Will let you know the result. Will be a few days they said!

Here is the latest. It was bumped up successfully by the shop. Brought it home. Turned on and getting the orange DRAM light on constantly. I have two sticks of G.Force F4-3200C16D-32GVK. Which is not on the supported memory list I found here! I tried just one stick at a time, cleaning the heads of each, restarting several times. No Go. Wouldn't post.

So I purchased 4 sticks of Corsair Vengeance LPX 16GB (2x8GB) DDR4 DRAM 3200MHz C16 Desktop Memory Kit - Black (CMK16GX4M2B3200C16) which are on the list. Still getting the orange light for DRAM.
I do not have an older CPU so if removed the CMOS chip that will reset it back to the original version that was too low.

Need some recommendations on next steps. Will be reviewing other links on here and see what I can find out.

Thanks!

Here is the latest to the latest. Took all the sticks out and now have a stick in the DIM A1 slot closest to the CPU and it posts and goes to the desktop. When I put a second stick in, it doesn't post at all. Going to update my system and hopefully all will be well. Stay tuned!

Reset CMOS with both sticks of memory in place, then restart. That will force the CPU to re-train memory.

It worked properly at the shop (I assume that is what this means, "It was bumped up successfully by the shop")? You witnessed this?

Also, at any time, has the CPU been inspected for bent/missing pins?

I took several shots of the CPU and looks clean.

They used their CPU and was able to get it to post just fine. They used their own memory too they said. My brother-in-law recommended I bump the bios down a notch. Did that, but no change and can only read memory now from the A2 slot.

 

[dengle1962]

So I reset the CMOS. I put one stick in only and that worked. I put a second one on in every place and wouldn't boot. I stuck all four in and didn't boot. Any good recommendations on utilities to test memory modules and motherboard for issues?
