HP 840 g1 6050a2560201 ram error

[Bisketti]

Hi this unit has black screen, caps lock blinks 3 times (Ram error) and fans run full speed. I have tried flash the bios/clean ME region/flash Ec but still the same.
It has DDR3L which is 1.35v and vtt is .67v . Any ideas welcome.

DDR3_DRAMRST is 0.126v on both slots.

ddr3L ram it uses, so DRAMRST should be 1.3V approx. So your reading is definitely wrong.

Hp site has only update and not full bios. You can post your dump here so that someone can merge it with official update to rule out bios issue.
