Yes i did remove the RAMS YES i did Try all four RAM Slots with both RAM sticks , if its one RAM it boots and also like i said above even having both my RAM Sticks in single channel (A1 , A2) slots it does boot too and recognize both of them ( am using the same PC to write here as you can see in the picture attached ) Yes i did check , i even bought a brand new motherboard just to be sure it's not a RAM slot issues , am having the Same scenario as my answers above Bent / damage CPU pin(s), affected the memory slots : i'm thinking the same , but i checked my CPU twice , its seems proper , if its only a one pin case scenario i think i might have to check the CPU again using a Magnifying Glass or something like that Damaged DIMM (memory) slot, when removing / reinstalling RAM : as i explained above the Slots are fine and the RAM sticks too please if you have some knowledge am missing or something please share , and Thank you for taking the time

Hello updating the bios didn't work ....

I didn't think about it , because they were working fine before but i'll give it a try and see Thank you i'll post the results this afternoon

Hello People , I hope everybody is doing fine in these times ? I need some help , am little bit confused AS the title said my PC won't boot with dual channel anymore to give you guys some context i have a Ryzen 5 3600, 2 days ago i bought an Air Cooler Thermaltake UX200 , i took out the stock cooler , installed my new air cooler ( didn't forget the termal paste , neither the plastic protection below the air cooler lol ) , powered on all the rbg lights up even the 2x8 ram sticks , the air cooler works fine i can also hear my SSDs and hard drive running but it didn't post , so than i started trouble shooting as below turned off everything , cut out the power cord , took out the CPU and checked it , am 90 % sure that there were no damaged or bent pin , put it back and power back on same issue , than i tried to boot with one stick of ram and it works fine , tried the second stick of ram , it also works , so no issues in both the Ram sticks , after that i tried to perform a CMOS reset and powered on with dual channel doesn't post , after that started again with one stick of ram entered bios setup and enabled XMP Profile , save and shut it down , put my rams on dual channel again won't boot as a last ressort , i put my 2x8 ram in single channel ( A1 and A2 Slots ) well my PC boots into windows and it recognize 16 Gb of RAM , so for now am using as it is . as i used mostly for games and am not seeing any difference but i want to know what caused dual channel not working ? and if i won't have any issues in the future running it in a Single channel Config ? lets suppose : could just one bent pin in the CPU cause this ? i don't know if anyone gonna read this long text , lol but if you do could anyone advise and give me some infos as this case is stressing me out , this my 5th build over the years and this the first time something like this happened Thank you BTW my config is : Asus Prime B450m-a Plus Ryzen 5 3600 Thermaletake UX200 Argb Air Cooler 2x8 GEIL Superluce 3200 Mhz Gigabyte GTX 1070 Gaming G1 OC rev2.0 ADATA SSD 128 GB Samsung 960 Evo NVME 256 Gb two 1 TB 7200 RPM HDDs Corsair VS650

@D13H4RD Thanks for your answer I double checked the PSU ( voltage seems fine to me ) , also the connectors are okay i've been playing this afternoon for hours without any led flashing again or weird noises from the PSU does this mean as long as i'm not overclocking component i should be fine ?

So any good lead anyone ?

@Kilrah yes i Thought so , i have a VS650 from Corsair , so if everything is back to stock , i should be fine right ?

Hello everyone , i hope you're doing okay ? i'm having a bit of a fear here , recently i bought a Gigabyte GTX 1070 G1 , it was working just fine then i Overclocked my CPU Ryzen 5 3400G , everything was working fine for a few days yesterday night i noticed that the power led in my GPU started flashing all of a sudden , no crashes or anything i immediatly reset my CPU to stock and kept monitoring the GPU power led for a 2 hours it didn't flash again my question is will the hardware be fine after this ? Does overclocking the CPU caused an abnormal power consumption after some point ? Please let me know if you need any details about my config or anything tell me Thanks BR
