Added more RAM but the computer still won't boot.
Added more RAM but the computer still won't boot.
I installed a new RAM module to upgrade to 32GB instead of the previous 16GB. Now my PC won't boot Windows. It worked fine with the other two RAM sticks I had before. Did I accidentally purchase the wrong type? The photo you shared shows the old stick, and the one I bought is the second one. Why would they make them so similar?
It's simple to run a memtest on a USB drive and check the RAM: https://www.memtest86.com/download.htm Start from BIOS, begin with the USB stick, keep the test going through one full pass (aim for at least 20 minutes). If errors appear, the RAM might be defective or, less commonly, the motherboard can't support that many sticks at such speeds—for instance, it could handle 1 or 2 sticks at 3200 MHz but only 2833–3000 with four. When errors occur, try inserting one stick at a time and rerun the test to see if just one causes issues. If none do, you can disable XMP or manually set the frequency to 3000 MHz, 2833, or even 2666 MHz to verify compatibility. The Corsair products generally work well. You haven't mentioned your motherboard model—do you have any updates for it?
Hello Roguezxro, welcome! It’s a challenge sharing details with you unless we have the motherboard specs, CPU specs, and RAM capacity. Start by looking up the QVL information from the manufacturer’s website—it’ll confirm if your RAM model is compatible with the board. Next, verify the slot type you installed; your manual should clarify that. Regarding the RAM type, did you get a quad or dual channel? Also, note the physical surface it came in. That data suggests those particular modules aren’t suitable for your system.
I recall a similar situation when I bought DDR4 memory for an older i9 9900X setup. My motherboard was an RTX 6 Extreme with an old CPU, and the RAM wasn’t working well. After some research, I found a compatible model that matched my needs. It took a bit of patience, but it paid off.
I’m following your advice to begin from scratch, marking each step. With a little effort and research, I’m confident we’ll resolve this. As for the MemTest86, it’s a reliable way to ensure stability once you’ve completed the tests.
If you run into any issues or need further details, just let me know. This was my i9 machine, and I’m now considering the Core Ultra 9. It’s been a long journey, but I appreciate your support.
Cheers, Kiwi000
Edit: Still got the TV and soundbar, though.
I purchased the identical RAM with matching serial numbers, which resolved the issue. Earlier units had different serial numbers. My CPU is an 8700K and supports a maximum of 2666 MHz. Exceeding this limit will prevent booting. It’s recommended to verify your CPU's supported speed before attempting overclocking.
You're asking about the meaning of identical serial numbers. They usually don't carry unique identification beyond that. The example you gave shows modules with nearly matching numbers except for a small change, suggesting they belong to the same batch. Since these were bought together as a set, it makes sense. But identical serial numbers seem confusing—most buyers wouldn't have access to just the number, only the part or model code.
