Omen 25L (GT15-0003na) - Tried to upgrade the RAM to run at 3200 MHz and not getting past POST

[Omen25Luser]

I tried to overclock the RAM on my Omen 25L to run at 3200 MHz, restarted and now I'm getting no display signal. Since then, I've noticed my PC isn't getting past POST and I have no power being provided to the USB ports. The fans and RGB lights on the CPU/RAM turn on but there are no diagnostic LEDs or sounds being made on the motherboard (as I understand there is no built in speaker).

I have taken the following steps to try to remediate the issue or narrow down what is causing the POST failure: 

• CMOS reset - completed multiple times, no effect.
• Cleaned inside the case as I had a buildup of dust. 
• Reseated the GPU, RAM and CPU.
• Removed all hardware components apart from the CPU, one stick of RAM (in slot 2) to see if it will POST with a paired down setup.
• Used a multimeter to ensure power is being provided to the BIOS chip. 

My current task is trying to flash the BIOS using a using a CH341a programmer. I have had some success reading the chip using NeoProgrammer V2.2.0.10 but I'm stuck trying to extract the .bin file needed to flash the chip. I'm using a Windows 11 VM on a MacBook as that is the only other PC I have. Can someone please help me extract the .bin file from HPs SoftPaq file - SP156625. I've managed to run the .exe, which then creates a directory in C:\SWSetup\sp156625 but when I run the corresponding file (089EB.exe) nothing happens. 

Any help or advice would be appreciated.

Welcome to the HP Forum.

Resetting CMOS should have fixed the problem unless something else has coincidentally happened.

You could try 7zip to examine the contents of the HP BIOS update file (sp156625.exe).

I have tried using 7zip to find the BIOS code but could never isolate it. Sp156625.exe has a lot of files and folders packed in the executable. The AMI BIOS Update Utility is packed in the executable file.

I did see some, what appears to be, encrypted text files. Maybe the binaries are in the text files.

You might have better luck and will be able to ID the code, it's in there somewhere.

Thanks Bill, I managed to find the .bin file and flashed the BIOS but still no luck. I wonder if anyone has a verified bios dump for this motherboard or if there is some hardware that is stopping the write in some way.

My pleasure.

Maybe the BIOS chip needs replacing.

Are you able to read and backup the current BIOS using the CH341a programmer?

Are you flashing the BIOS with the BIOS chip connected to the MB?

You might get better results if you remove the BIOS chip from the MB and connect it directly to the CH341a programmer.

this is your bus type (Memory type: 256M x 32 GDDR6 with 8 sticks) each one being 2GB gddr6 you need to get to 3200 u need ddr6 3200 4gb stick for a total of 8 sticks

Thanks again for coming back to me. I was trying to flash it using the SOC8 clip but after numerous failed attempts, my next step is to desolder the BIOS chip to see If that will work any better. Failing that, I think i might be in for a new BIOS chip or worst case scenario, a new motherboard.

My pleasure.

I've had some issues in the past using the CH341a programmer. So I switched to an RT 809F programmer.

As we are both thinking, the BIOs chip could have failed or the MB has a different problem. Spending more money on a different programmer might be a dead end.

Let the Forum know if you solve the BIOS problem..
