pc fails to boot when using dual-channel ram
pc fails to boot when using dual-channel ram
i just rebuilt my pc and it isn't booting in dual channel mode.
my system is failing to start when:
1. rams on slot 1, 3 or 2 and 4 – the dram and cpu debug lights flash erratically, then the cpu restarts repeatedly while the system stays stuck.
2. it boots normally with single ram in every slot – rams are working in slots 1, 2, 3, and 4, including 1 & 4, 2 & 3.
here are my current specs:
cpu – 7700k
ram – gskill trident z 3200
vga – intel hd
motherboard – msi z270 gaming pro carbon
if necessary i'd look for a more recent bios version for your mobo
if that doesn't help, it seems there could be a bent pin in the mobo socket
even a small bend in just one pin might disrupt memory performance
so if the bios update isn't resolving the issue or is already current, then removing the cpu and carefully inspecting the socket pins (using a magnifying glass if needed) would be the best approach
With both RAM sticks installed, is it possible to access the BIOS? If so, verify that the appropriate RAM timings and voltage settings are set for your specific memory type.
when you have both ram sticks installed, can you access the bios? If possible, verify that the right ram timings and voltage are set for your memory type during the first boot after rebuilding. During the looping issue—where the system stuck on a 1-second loop, turned off, and restarted—all four rams, cpu vga, and boot debug led blinked one after another—this helped. After that, using just one ram worked fine. Then I tried dual channel with two rams in adjacent slots, and it functioned properly.
when it boots, the BIOS applies specific RAM configurations to ensure proper operation.
when using both sticks individually, do they follow the manufacturer's suggested timing or voltage guidelines? and are they tested for memory retention under those conditions?
when using both sticks individually, do they adhere to the manufacturer's suggested settings and voltage? additionally, does each stick undergo a memory test when operating alone? yes, everything is set according to the manufacturer's recommendations and each stick passes its own memory test.

i accidentally bent a pin i found
it worked fine but ram slots 3 and 4 aren't functioning
should i risk bending it again to get dual channel?
