The computer fails to start when a RAM stick is placed in the first or second slot on the new motherboard.
I’ve gone through several steps with my computer recently. I purchased a pre-assembled build from NZXT, but after a few years it began to vibrate excessively. Despite my efforts to fix it, the issue persisted. I opted for a replacement AIO cooler, specifically the Arctic Liquid Freezer III 240mm, based on positive reviews. When it arrived, I attempted to remove the old unit and install the new one. After completing the installation, my PC failed to boot. A quick inspection revealed bent pins on the motherboard, which I couldn’t reposition properly. I tried reinstalling the AIO again but faced repeated boot failures. Eventually, I managed to get the system running if both RAM sticks were placed in the 3rd and 4th slots.
A friend suggested this might be due to CPU damage, possibly from the thermal paste application during the swap. He also recommended switching to a DDR5 motherboard instead of a DDR4 one for improved performance. I followed his advice and upgraded to an Asus PRIME Z790-P WIFI ATX LGA1700 motherboard along with Corsair Vengeance RGB 32 GB DDR5-6000 CL30 RAM.
During the replacement process, I realized I’d applied too much thermal paste to the CPU, with some spilling onto the green components and the underside. After cleaning as much as possible, I installed the CPU into the new cooler with the updated AIO. Once everything was assembled, I tried booting the PC, but it still wouldn’t start unless the RAM was in the 3rd and 4th slots.
I suspect this issue might be linked to the CPU itself, possibly due to damage incurred between removing and installing the old AIO. I’m still learning about PC components, so any additional factors could be contributing. The spec sheet and parts list indicate compatibility, but I’m open to other possibilities.
Based on what @Blasty Blosty mentioned, I believe the problem might stem from mounting pressure. Consider slightly tightening the CPU and observe if it improves your situation. It’s also a cost-effective solution instead of purchasing additional components. The added clamping force may allow the CPU pads to make better contact with the pins below.
Excessive pressure is a common issue. By the way, I wasn't aware you could boost it.
Yes, a bit more pressure is needed, it's not as tight as you might think. Certain fasteners don't require extra force and simply snap into position, while others have adjustable screws that let you tighten further. The OP cooler can be adjusted more precisely, not just clicking into one spot.
You're referring to the cooler pressure versus the loading mechanism pressure. I would have chosen the latter, but the former could also work. Edited February 17, 2025 by leclod
I'd get a cheap contact frame from amazon or aliexpress. This is a good thing anyway with your cpu. And I'd check again for bent pins or paste in the wrong place, because your story is concerning. Edited February 17, 2025 by leclod
I followed your advice and placed the RAM in the second and fourth slots. I was able to boot into BIOS and confirmed both sticks were recognized correctly. The system passed a 3Dmark stress test with good results. I’m not certain about the source’s reliability, but it worked fine. I’ve also noticed the AIO I’m using can be tricky to install, possibly due to over-tightening. Thanks for the assistance!
The AIO came with its own contact frame. I’ve seen online reviews suggesting that unless you handle the screws carefully, the water block might not sit fully on the CPU. The solution for my issue was securing the two screws on the water block tightly. Even though it was just starting to fit, it was difficult to tighten them properly, but once I felt confident it was secure, the problem was resolved.
