I see what you mean. I loaded up the 520W vbios and now am crashing on memory around 1300. I ran your settings and got a 15375, but tried to go higher and crash city or no complete. It seems like a whole relearn when you switch the bios switch. That was with 1.1V nvvdd only adjustment.
I think you may have mentioned it before...your memory timing adjustment. I think that's where you got your extra 400 points. First run on your clocks netted a 15048, but after adjusting the memory.... 15375. I'm using the same driver as well.
Edit:
Using my 10900K and not 4930K setup.
5.3Ghz/4400 Mhz memory.
The memory settings really aren't too awfully special, 4000MHz at 1.43V, CL17-17-17-38 2T with tRFC at 300, tREFI of 22500 (haven't really messed with that much), everything else is just what the BIOS or sticks read out at at stock, manually inputted so the BIOS doesn't do anything stupid like putting them tighter or extremely loose. Don't think I could go much higher on speed even with looser timings. I actually used that as daily settings for a while with 1.42V and tRFC of 350, but it gave me a crash or two in Cyberpunk so I reset the RAM to stock for my daily-usage settings, 3600MHz @ 1.35V CL16 isn't too bad.
And those are the same RAM settings I ran before when I was only getting 15037 - switching drivers twice then reverting back to the latest just magically gave me almost 400pts and I have no clue why, but I approve. I'm sure the cooler temps were a slight increase, but no way it was that much. Maybe DDU caught something it didn't before and cleaning that up made the difference.
With what you experienced switching to the 520W BIOS, maybe it is indeed a memory timing thing or something preventing higher vRAM/memory clocks. But even on the "Normal" BIOS switch position, I was able to run +150/+1250, couldn't go any higher without crashing, but my score was also only around 14.9k... but that was also with 72F ambient so who knows.
It definitely seems like I got some meh-worthy Memory on my card though - I'm going to try pumping it up to 1.4V on the vRAM next time I test, see if maybe that will let me run +1300-1350-1500 or thereabouts... with the fact that it crashes at +1300 but passes at +1250 every time, I have my doubts. What is the stock FBVDD setting anyway, 1.36875 or 1.375?
