Was das Gerät deines Freundes beschädigt?
So my buddy came over because he got a new computer and asked me to take a look (it was used). It looked clean, but the RAM seemed to be running at 1333MHz—thats odd. When I checked the BIOS, it showed a higher frequency than expected (2666 or something), and then changed it to 3200, which matched the rating. At lunch my PC froze, so I lowered it to 3000 and it worked fine. He mentioned overclocking, so we discussed checking the power supply before even thinking about that. He had a case where the PSU was hidden, so we removed the back panel. The PSU looked like Ace-tech or similar. I didn’t know the exact brand, but he told me to wait until we got a better one.
I noticed the RAM was placed in the last two slots on the motherboard (MB), which were colored black and grey. I thought I should verify the manual, but it said B1, B2 and those slots were grey. I moved one stick over. Now the PC starts up but doesn’t display anything. The motherboard lights stay lit even when I switch the PSU. I changed screens, HDMI connections, and plugged in different ports, but nothing worked. I mentioned this to general troubleshooting since I’m not planning to fix it right now (I think it’s a PSU issue).
I’m unsure if I accidentally damaged his computer. TL;DR: The RAM was installed incorrectly—probably not all slots were filled properly. I felt embarrassed when I realized it, but he was okay for a day.
Adjusting the RAM position back to its original slot and resetting the CMOS can resolve the problem. Clearing the CMOS typically involves removing the small battery on the motherboard, waiting briefly, then reinserting it. The speed you mentioned—1333 MT/s to 3200 MT/s—represents a substantial increase. This high rate may not function properly in dual-channel configurations, though it might have worked in single-channel mode. The number 1333 aligns with DDR3 specifications, which officially max out at 1866 MT/s. Reducing the speed to match that standard could improve compatibility in dual-channel setups.
Replace the CMOS battery; locate it on the motherboard, gently remove it, let it sit briefly, then reinstall. This restarts the BIOS and likely fixes many problems with "not booting," particularly after moving RAM. I try it by leaving it out for 5 to 10 minutes, though you probably don’t need that long.
I included extra information, though I’m not sure about the details from the pawnshop. The PC was used for just a few hours.
I moved from 1333 to 3000 because the BIOS indicated it was DDR4 3200. At first it looked like questionable RAM, though I’m not sure. It turned out I changed the RAM back and still didn’t see an image—probably because the boot process doesn’t display pictures. I forgot to clear the CMOS, which I’ll fix today.
After resetting the CMOS, verify for any BIOS updates. Use HWinfo64 to see detailed hardware information such as manufacturer release dates and BIOS version. The memory could have been installed in single-channel mode, which might be due to the board being from the 4–5 year range—possibly requiring a fresh CMOS battery. These batteries are affordable and have their type stamped directly on them, preventing mix-ups. It’s possible there’s a memory channel issue, but if it functions properly in single-channel mode, you shouldn’t be too concerned, especially since you likely got a good deal on the PC.
It's highly improbable you damaged your friend's PC, especially after the previous owner chose a low-cost PSU. You should avoid using it, as it may not supply sufficient power anymore. The best chance is it wasn't designed to handle failures and prevent AC current from reaching sensitive components—though since the system starts up, that risk seems minimal.
The process of "cheapening out on the PSU" reduces the chance of damaging the computer because it lowers the risk involved. Cheaping out usually means using lower-quality parts, which makes breaking down the system less likely.
It’s unclear exactly what they did to the PSU, but we don’t know the brand or model. It could be a generic low-end unit or a high-performance one from a reputable maker like Antec.
Overclocking the RAM and switching to dual channel has minimal impact on power use. This change is unlikely to cause power-related problems; instead, it’s more likely affecting stability due to increased frequency in the RAM.
Revert the memory to its original slots, disconnect the PC from the power source, remove the CMOS battery for a short time, then reinstall it. After restarting, if the utility reports RAM speed as 1333, it might actually be operating at 2666 but only at half capacity.
