/UPDATE
NVM, BIOS also reset the boot type it seems when detected the new ram, forgot the LSI card has no output when in UEFI boot mode… -.-’
Hello all!
Is it possible to kill pcie connectivity on an old mobo/new-ish cpu (<- bought cpu 1-2 years ago) by upgrading an existing system to full capacity from half (2x32GB → 4x32GB, same with exact same DC dimm kit)?
Because to me it seems like it just happened to me. Popped the new kit in, powered it on, it did the usual reset (happened on 1st start on any mobo i upgraded the RAM). After that i thought it would just boot up as usual but no, the VGA POST diag led is on (mobo has a diag leds for both the POST and dimm/pcie slots). None of the populated pcie slot diag leds are on, interestingly the 4 dimms had the leds on.
What i have tried so far:
- full bios reset (switch off PSU, pop battery out, waited about 5 minutres)
- take out new ram
- reseat gpu
- try different gpu
Relevant HW:
- MS7A33 MOBO
- 5950X CPU
- Corsair RAM 2x CMK64GX4M2D3600C18
- GTX1660 GPU
- GT710 test GPU
