Qcode 8 with the DRAM led lit indicates a problem with RAM. Either you have a mismatch or the MB DRAM slots are dead.
As POST will not advance till DRAM led problem is resolved best is to clear CMOS then test slot functionality with just one DIMM and testing each slot. Testing also with another kit at 2666MHz is worth a try.

Bought a new 4gb stick at the local computer store, still getting qcoding 8 Dram led flashing can't get past a UEFI usb drive fresh install of Windows 10, I don't know what to do at this point besides remounting my H150i pro bracket or RMAing my motherboard. I don't understand how it worked perfectly up till now.

Well if your DIMMs are all OK and well seated, you cleared CMOS to no avail and tested a 2666MHz 4GB DIMM to test, then it's time to RMA the MB as the only other thing I can think of is the new PSU. (Very doubtful being more than enough wattage and a quality product)
Hope you get it sorted :confused:

New edit: System works with all manual voltages using recommended voltages from another C7H OC thread on Overclockers.net, had to change SOC voltage to 1.15V, CPU voltage to 1.35V, DRAM voltage to 1.4V and CLDO_VDDP to 980mV. Set all voltages manually. Set RAM to 2133MT/s too.
Not sure why Auto worked for so long and why this is working now, that being said I have a day till my RMA label shows up. Should I still RMA the board?

Updating or flashing Bios for the sake of it is not the best idea and should be done only as requirement to fix an issue regarding performance.
If the system is performing well and stable then leave it or be prepared to begin Bios tuning from scratch.
Glad you have it sorted 🙂

Well, that is usually a good advice, but IMHO not in the case of this mobo… every BIOS update from Asus ha risen the level of compatibility especially with RAM.
If I was in the OP's shoes I would go for RMA, even at the risk of being rejected. The mobo MUST work with a supported CPU and everything set to Auto in BIOS… if it does not, it's faulty meaning it's not capable of give the correct volts for that kind of CPU.
The final test would be another CPU in the 'faulty' mobo but it's not an easy try to do.

As you quoted me I felt compelled to answer re your Opinion.
First I disagree with your suggestion to RMA the MB unless definitive evidence of failure is found. (A profound inconvenience, Dissembling, Transport and cost, not to mention dealing with ASUS Support) The OP has a compatible MB and CPU so definitely no issue there.
I have this MB and have had no issues with my 2700X with either Overclocking to 4.2GHz or compatibility with RAM at 3200MHz. (Original Bios)
Yes it required some Bios and RAM Tweaking which I consider a normal task. I consider it best practice to stress test initially at default to check on such things as Rail voltages (under load), Temperatures and sensors, RAM Timings etc.
Auto Overclocks do and tend to Overvolt needlessly however without any major safety issue. It may result in unacceptable temperature levels however Core voltage is easily rectified and a necessity to obtain a stable OC.
