Hi all My main development machiene died today, so expect increased delays about things that involve me/it until thats fixed Rest of the mail is just about the issue, and you can skip reading that Timeline: box suddenly stopped, no reaction to any input or pings power off and on did not bring it back, screen stayed dark, keyboard too but fans spin up and theres power opening it up i find it stuck on Q-code "0d" so i power it off wiggle the ram modules a bit power it back on and it gets stuck on qcode "15" i power cycle again and it reaches bios setup, so i go over all values and just look but as i look, it hangs hard again off/on again and we hit "0d" again so i remove one of the CPU fans to get to the DIMM modules and reconfigure them like this: B1A1 0+2 -> boot ok B2A2 0+2 -> boot ok B2A2 1+3 -> 0d B2A2 0+3 -> boot ok B1A1 1+2 -> 0d This is consistent with DIMM module 1 being faulty. But iam not 100% convinced because this box never crashed not once, it was always rock solid and suddenly one module is so faulty the box hangs so early. Either way i ordered 4 new and bigger modules from 2 independant shops they should be here soon but i dont know what "soon" is around christmess also i could try running it with just 2 modules, i might try that tomorrow RAM modules are: G.Skill Trident Z F4-3600C15D-16GTZ DDr4-3600 CL15-15-15 1.35v 8Gb manufaturing date 2019 Dec MOBO is: ASUS ROG STRIX X570-E Gaming PS: i could have gotten the modules quicker but i was trying to get 4x16gb to double the 4x8gb and have them not slower. And it seems that constrains me to 2-3days waiting at quickest. PS2: The faulty module looks perfectly fine and all look suprisingly clean thx -- Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB In fact, the RIAA has been known to suggest that students drop out of college or go to community college in order to be able to afford settlements. -- The RIAA
