Strange issue (ram) Acer Predator PO3-640

Hello everyone. I recently opened my PC (model and specs below) to change the thermal paste because the processor was overheating quite a bit (90 to 95 degrees during testing). Well, an important detail when opening the PC: one screw from the cooler was stuck, and I had to forcefully try to remove it by hand without success, so I had to come up with a method of turning the cooler in such a way that I could apply thermal paste without detaching it from the motherboard, which resulted in me removing the graphics card and all the cables connected to the motherboard. So I managed to apply the thermal paste, reconnected the graphics card, the cables, etc. and then I turned on the PC, and suddenly, I heard a long continuous beep with no display on the screen. I got worried and searched online where they told me that this beep indicated a problem with the RAM. I then turned off the PC and unplugged and replugged the RAM, but it still didn't work. I then tried different modules (I have 2 sticks), and it didn't work until I removed 1 stick and placed the remaining one in B2, which allowed me to turn on my PC without a beep and get a display. But both sticks still don’t work together, so I tried for a while to place the 2 sticks respectively in B1 and B2 (not in dual channel) and the PC turned on without any apparent problems until I launched a stress test that caused the image to freeze and crash automatically.

Specs
Model: Acer Predator Orion 3000 PO3-640
CPU: i7 12700F
GPU: RTX 3060 TI
RAM: 2x16GB Kingston Fury 3200mhz

Thanks in advance. Feel free to reach out if you have even a hint of a solution.

Hi

It's likely that you didn't discharge static electricity before touching the inside of your PC...

The RAM sticks are very sensitive and fragile to this issue, and you have clearly fried one of the sticks....

Under Windows, there is a RAM testing module, try running that first to see what it says.

Another possibility, since the heatsink doesn't seem well installed, it's possible that the CPU is not seated properly and since the memory controller is integrated into the CPU.....

Hello,

thank you for your reply. I tested each stick in slot B2 with the Windows RAM diagnostic, and apparently there’s no problem. Could it be the other 3 slots that aren’t working?

Hello, I have tested each slot one by one, and as a result, my 2 RAM sticks work on B1 and B2 but not on A1 and A2. I also tried both sticks together in B1 and B2, and it seems to work, but that's annoying because there’s no dual channel.

Good evening,

Could you once started, open a PowerShell terminal and run this command? Please post a screenshot of the window to see the result:

 Get-WmiObject -Class "Win32_PhysicalMemoryArray" -namespace "root\CIMV2" | Select-Object __SERVER,Caption,Description,MemoryDevices,MemoryErrorCorrection

Everything is detected here, all is OK.

Have you tried disabling XMP in the BIOS?

And this command:

 Get-WmiObject CIM_PhysicalMemory | Select-Object BankLabel, DeviceLocator, Manufacturer, PartNumber, SerialNumber, @{Name = 'Capacity'; Expression = {"$($_.Capacity / 1gb)" + 'GB'}}, @{Name = 'Speed';Expression = {"$($_.Speed)" + 'Mhz'}}, @{Name = 'ConfiguredClockSpeed';Expression = {"$($_. ConfiguredClockSpeed)" + 'Mhz'}},@{Name = 'Voltage';Expression = {"$($_.ConfiguredVoltage / 1000)" + 'v'}}

It seems to work but it's annoying because there's no dual channel.

The performance loss is impossible to measure in use, it's really not a problem.
