Thanks for your reply, in the bios I can set the values manually or as an offset, alternatively can also leave them on Auto. First post on 1.05 worked after turning PSU on or off, but as temperamental this issue is, there's no way to tell if this will happen every time. I will try and test it tomorrow at different voltages to see if any value is more stable than another. EDIT: At 1.1v It seemed stable for a while but then this afternoon hung on the Yellow DRAM indicator after a cold boot. A single force power on and off rectified this and the system posted. Due to the inconsistency of this issue, i'm not sure whether this is some kind of hardware issue or some software compatibility issue that can be rectified down the line with e.g. BIOS updates or Ram Timings Tweaking. Thanks.

Hi all, I've just built my new PC and chosen the Asus x470 Gaming-F Motherboard + Ryzen 7 3700X, combined with Corsair Vengence RGB Pro RAM (4*8GB sticks DDR4 3200Mhz C16) and the compatibility is proving to be an absolute nightmare.I've spent a week troubleshooting the issue of the Computer not always posting, landing on the yellow DRAM LED when it decides not to post. Whether it does post or not is entirely unpredictable, which is weird.I have two reddit threads about it where my full explanation of what I have tried to do to fix it, without much luck, linked here:https://www.reddit.com/r/ASUS/commen...gf_yellow_led/https://www.reddit.com/r/techsupport...o_and_corsair/In summary I've: Reseated the RAM and Power cables + other components on the Mobo besides reseating the CPU. Tried one stick of a RAM at a time (Problem persisted at least once on all four ram sticks Ran mem test 86 on 3 passes with 0 failures with the DOCP Profile enabled and the system decided to post. Tried the XMP readouts from CPU-Z and enter them manually 16 18 18 18 36 54 (The last one being tRc), with 3200Mhz selected + 1.35V. This proved the most problematic, 2 BSOD's + Many issues in HCIDesign Memtest. Tried the same as above but with 56 tRc (had seen this suggested on another thread). This proved the most stable with 3 full cold boots being successful (with PSU Being switched Off/On too, which has always made an impact at some point in all this troubleshooting), but after shutting the system down later on it took 4-5 attempts to get it running again else it would just sit on the Yellow DRAM light. Used Ryzen Master Calculator's safe settings, (I entered the XMP correctly as a HTML output from "Thaiphoon" software. These settings caused my computer to just boot loop until safe mode was activated. Finally, when DOCP is not enabled and the ram sits at 2133Mhz, it seems to be completely stable (as far as I can tell) Despite this, when the system posts WITH DOCP Enabled (Or manually entered the DOCP timings of the Ram, (16-18-18-18-36 + TrC set to Auto as DOCP profile doesn't set this even though it should be 54 according to Cpu-Z XMP Profile) will eventually post after cycling through power numerous times, and once it's in the OS, the Computer is completely stable with no BSODS or anything. For reference, I am on the latest BIOS Version available, 5406, with updated chipset drivers (Which I have reinstalled).Any advice on what to do would be greatly appreciated as I am completely out of ideas. Thanks.
