The new PC does not start properly when specific RAM modules are added.
Hey, Building a new PC from scratch, but I've had issues with RAM. I've got the following setup: ASRock B550M PG RIPTIDE AMD Ryzen 5 5600G Silicon Power Gaming DDR4 32GB (16GBx2) 3200MHz Here's my story: Initially, I tested outside the case. System didn't POST. Removed RAM stick #2. Still didn't POST. Removed stick #1, put stick #2 back in. System successfully POSTs! Tested both sticks in all four slots. Stick #2 always works. Stick #1 always fails. No biggie. Ordered replacement RAM. Continued assembling PC with 1 stick of RAM. Everything is working great. Replacement RAM arrives. Put both sticks in (#3 and #4). System doesn't POST. Test each stick individually. Neither stick works in any slot. Retest with stick #2 (known-good). System successfully POSTs again. I've tested every combination: With stick #2 in any slot, system always successfully POSTs. With sticks #1, #3, and #4 in any slot, system never POSTs. Notes: When it doesn't POST, the motherboard has both the CPU and DRAM LEDs lit I've done a CMOS reset. No BIOS configuration since then, everything is left at defaults One observation, when the system does POST with stick #2, the BIOS reports DDR4-2666. I expected this to be DDR4-3200 Any ideas? One bad stick of RAM is understandable. 3/4 failures makes me think something else is up. Thanks in advance!
Are you sure the motherboard accepts 16GB modules? Would you attempt using inexpensive 4GB sticks from another supplier? If it shows up with those, it might mean insufficient RAM or incompatible sticks; if not, it could indicate a faulty motherboard. Is the required RAM listed in its hardware specifications?
What replacement RAM have you purchased? Right now I’m just swapping the board because it’s unlikely many sticks will fail like this unless you’re extremely skilled at unlocking. Since you only bought two kits, it might just be luck that three sticks are dead and you’re really unlucky. Get some inexpensive 4GB (under $15) or 8GB (under $25) bare PCBs, but don’t just grab any random ones with mixed ICs. I suggest getting specific ones. For a 4GB, look for Samsung K4A4G085WE/DE (4GBit E/D die, E is preferred) and for an 8GB, K4A8G085WD (8GBit D die). A micron-level 8GBit revision from d9vpp-c9bjz is also a solid choice. Samsung is almost always compatible, so if it doesn’t work then the issue is likely with the motherboard itself.
Hey everyone! The new RAM (Corsair Vengeance LPX 32GB) installed right away. I think I should keep checking compatibility lists next time.
