Gotta love Corsair! (Multiple DOA kits???)
So to start,
BACKGROUND: I chose to finally upgrade my system (i7 8700k). I went with the bundle on micro centers website. AMD 9850X3D, ASUS B850e TUF GAMING WIFI board, and Corsair 6000 CL36 ram. I assembled everything with the supporting parts, and booted it up 2 days ago. Things didn’t seem quite right, it was having issues booting (slow some times fast others). I had the feeling something was off. But I continued with my usually set up routine, checked the bios version, saw it was a year old. Looked up the bios version to see if anyone had problems…. What do you know it was a known 98*0X3D frier : ) so after regretting my purchase of an ASUS motherboard, I flashed what was the latest bios (which ofc now is an old version because they dropped a new one again while I’m in the middle of working on it yesterday). Both are beta versions btw but the one I have is 1670.
PROBLEM: After all of the set up and bios flash, something was still off, so I installed MemTest86 onto a flash drive, booted into it and ran the test (ALL STOCK BIOS SETTINGS EXCEPT PBO OFF AND NO EXPO FOR THE RAM IT WAS RUN AT 4800). With both sticks in it threw out 36 errors in just under 4 mins, impressive! I did the usual then, shut it down pulled the B2 stick out and ran with one stick in A2. First Stick in A2 was fine so I swapped it and tested the other stick. 36 errors (all single bit) and climbing again. Figured it was likely bad and chose to pull the kit right then and there and then exchange it.
Went to micro center swapped it with a fresh kit and went home. Plugged both in, booted memtest86 and again more errors, this time only 2 but again also single bit. So after debating about punching a hole in the wall because this was already my second hour and a half drive to my nearest micro center. I began testing the ram more in-depth to see if I could pin point the exact problems. FIRST the sticks, I ran each stick individually in A2. One came back clean, one flagged the same 2 single bit errors. I then tested the bad stick in B2 to see if the errors followed it. Again 2 single bit errors (I believe it was test 10 of each pass where it failed). So ok again a bad stick right? At this point I panicked and suspected my Mobo was somehow randomly kill ram modules. So I put the good stick in B2 and ran another test. Good stick came back clean in B2.
HELP: What could possibly even be going wrong here other than just incredibly bad luck with ram? CORRECT ME IF IM WRONG, but if I test individually with both sticks, and both slots, I can eliminate the CPU and Mobo as a cause of problems for my system with the results I got???
Do the PC building gods just hate me so much that I managed to get handed 2 bad kits of ram off the shelf? Where do I even go from here? To the incredibly dedicated and smart people of reddit that deal with problems like this daily please help.
TLDR: Bought a micro center bundle deal for a new build. Tested ram right away after assembling, determined I had a bad stick, went back to micro center and exchanged it. When I plugged the new kit in and tested again, same issue one stick causing problems. Even with extensive testing I am 99% sure I narrowed it down to a ram problem not anything else. But could use help or advice!
