PC Won't Boot after Install of Identical RAM in Last Open Slot

Hey folks,

I just got a final stick of RAM to fill all my mother board slots. I currently have 3 of 4 slots filled with Corsair Vengeance LPX 8GB 2400MHz DDR4, for a total of 24GB RAM. The new RAM stick is identical in every way, including timing (16-16-16-39 on both). The only difference between the RAM sticks are the version numbers, which are ver 5.30 on existing and ver 3.32 on the new. I could be mistaken, but I do not think version number would factor in provided the main specifications are equivalent.

I turned off my PC and installed the new RAM in the final slot, however my PC failed to boot (screens were powered on/connected by blank; mouse and keyboard did not light up). I removed the new RAM stick and my PC booted properly. What might I be missing here? Is there some procedure or installation order for installing a final stick of RAM? I recall the slot order the RAM is installed in matters when not using all the slots. Is this related to installing RAM in the final slot?\

Thanks in advance for any information or advice. I noticed some differences between memory sizes for physical and virtual RAM while reviewing system info:

Installed Physical Memory RAM: 24.0GB

Total Physical Memory: 23.9GB

Available Physical Memory: 18.8GB

Total Virtual Memory: 32 GB

Available Virtual Memory: 25.9 GB

System Info:

OS: Win10

Motherboard: Gigabyte AB350M-DS3H

Processor: AMD Ryzen 5 2400G, 3600 MHz, 4 Core

Boot Drive: WD SN-850X 2TB - NVMe SSD

Exist RAM: (x3) Corsair Vengeance LPX 8GB 2400MHz DDR4

GPU: NVIDIA GTX 1060 6GB

    Hey Bernard,

    I tried what you recommended: I installed the RAM in slot #1 into slot #4 so slots #2-3-4 were filled, but the PC did not boot. I put the new stick in to slot #1 and left slot #4 empty, and it booted. I also tried leaving the new Ram in slot #1 and installing the old RAM into slot #4, but it would not boot.

    Hi, and thanks for reaching out. My name is Bernard a Windows fan like you. I'll be happy to help you out today.

    I understand the issue you have, there is nothing to worry I am here to help, technically it should have a slight factor since it is a different version however, as long as the 4th RAM you install has identical specifications (2400MHz DDR4) it should be fine, in addition, this might be a slot or the 4th RAM itself is not working, to check it follow the steps below:

    Try to remove the RAM in Slot 1 and put it on Slot 4, which means your 3 RAMs are sitting in Slot 2,3,4, then try to boot the PC, if the PC boots up normally that means there is no problem with the slot, and the issue is with the RAM you purchased.

    Let me know how it goes and I hope that helps.

    Bernard

    Hi, thanks for that information, in this case, I am positive that the issue is the slot 4 of the motherboard, in this case, I suggest contacting a local technician to physically check the device for any hardware-related issues specifically the memory slot #4 of the motherboard.
