[PG Riptide Wifi] Stuck on cpu+dram LED, unless...

Alright so Im currently pulling my hair out over this

I have yesterday build a new system comprised of

Asrock B650E PG Riptide WiFi (new)

AMD Ryzen 7600x (new)

2x Samsung DIMM 16GB, DDR5-4800, CL40-40-40-77, on-die ECC [M323R2GA3BB0-CQK] (new, lets call the two sticks alice and bob)

NH-D15 (from previous build, known good and working)

Seasonic Prime TX-750 750W PSU (from previous build, known good and working)

GTX 770 (from previous build, known good and working)


I checked beforehand that the samsung ram is on the QVL of the motherboard

Putting it all together and starting it for the first time resulted in.. all fans spinning(probably at max speed, they are pretty loud), motherboard rgb kicking on aaand solid red lights from the cpu and dram debug leds from the second I push the power button and it stays like that until I longpress the power button to shut it down. It never does anything else, no blinking, no other leds come on even for an instant, its just a solid light on both cpu+dram.

The mother board has 4 ram slots and the manual advises you to fill the furthest slot from the socket first, leave one free then populate the next.

Trying around a bit I've gotten it to post if and only if I use Alice in the slot furthest from the cpu socket and nothing else:

- alice in the furthest slot+gpu and everything else connected: Success! I get to boot the OS with graphics output after a minute

- alice in the furthest slot with everything but Mobo and cpu fan disconnected: Success! I get to bios just fine after a minute

- alice in the second furthest slot with everything but Mobo and cpu fan disconnected: Fail! cpu+dram lights indefinitely(waited 20 minutes)

- alice in the third furthest slot with everything but Mobo and cpu fan disconnected: Fail! cpu+dram lights indefinitely(waited 20 minutes)

- alice in the fourth furthest slot with everything but Mobo and cpu fan disconnected: Fail! cpu+dram lights indefinitely(waited 20 minutes)

- bob in the furthest slot+gpu and everything else connected: Fail! cpu+dram lights indefinitely(waited 20 minutes)

- bob in the furthest slot with everything but Mobo and cpu fan disconnected: Fail! cpu+dram lights indefinitely(waited 20 minutes)

- alice in the furthest slot and bob in the second furthest slot with everything but Mobo and cpu fan disconnected: Fail! cpu+dram lights indefinitely(waited 20 minutes)


Yes, I did actually wait 20 minutes for each try because I read that the first boot times on AM5 can be ludicrous.

With most of those I did disconnect the power cable and jump the clear cmos pins with the noctua screw driver thing before trying to run them.

I dont have another cpu or ram to test with. I also dont have friends( ._.) I could borrow those from to test.

Honestly Im not entirely sure what to make of this. This feels like bob is dead and 3 out of 4 ram slots in my mobo are dead, which seems wildly unlikely.

I have not tried reseating the cpu yet because thats kind of a hassle(and for fear of getting thermalpaste everywhere and possibly bending the mobo pins while messing with that). Has anyone seen anything like that before or any idea on what that might be?

Also none of my components had any visual defects.. that I could pick up on anyways.


Im on bios version 1.11(I used the bios flashback to put it there myself) which is the most recent not beta bios asrock lists. But I have also tried the 1.11.AS03 beta and got the same results.

I would send email to ASRock support.

My board is the B650E PG Riptide WiFi, not B650M:

Unless Im reading the QVL wrong 'DIMM Socket Support:2' should mean it supports up to 2 dimms of that brand, right?

Have you tried removing the video card and using onboard iGPU?

What BIOS version are you running?

For what it?™s worth, I have an ASRock B650E PG Riptide WiFi motherboard as well. Specs are as follows:

AMD RyZen 9 7950X
ASRock B650E PG Riptide WiFi
G.Skill 32GB (2x 16GB) kit F5-6000J3238F16GX2-FX5
Samsung 1TB NVMe
CoolerMaster Master Liquid 240mm AIO
650W PSU
Windows 11 Pro

I?™ve seen something similar as in stuck on LED error and had a blank screen. This was mainly with a GTX 970 video card. I pulled the video card from the system and just used the iGPU and the error went away. The GTX 970 video card worked initially for BiOs setup but after that it wouldn?™t display anything and no it wasn?™t the BIOS settings. The card works fine in another system BTW.

I?™ve also tried a GTX 1060, GTX 760 and RTX 3050 all worked. Something about the GTX 970 was an issue.

There are stability issues it that is a different problem.

Im currently waiting for the new ram to arrive, ordered a different brand this time(also from the QVL). If its still making trouble after that I'll send the board back to get it replaced, since dead cpu is wildly unlikely.

I tried it with and without my trusty GTX 770 (obviously also plugged into the right display ports) and I tried the most recent beta and non beta versions of the bios(flashed through flashback), all of which gave me the same results(yes I went through all permutations of both). Im reasonably certain its not that. I also know it works fine and I can get it to boot in one specific configuration.
At this point Im really sure its either motherboard ram slots, the ram sticks I ordered or both.

Also Dram+CPU red light of death After around 3 weeks it happend that at one point the fans started to spin at full speed and screen turned black just like urs. After trying around with different graphicscards and Powersupply even reseating cpu etc... didnt work out to change the state. I then took the system to my next pc store (which i normaly hate to do since they charge me big money for things a monkey can do like swapping ram with different kits for testing costs 20?? so I paid 50??in total in the end to get there diagnosis that the board is faulty. ATM everything is taken apart again and send back to my retailer i bought it from and now I´m waiting for an RMA. The only thing is that even the shop couldnt confirm if the failure comes from the Board or the CPU since they didnt want to open a new one just for testing.

That sucks, at least you had a working system at one point. I know thats not much, but its more than Im getting :P
