Overclocking 6900xt vs undervolting, reminds me of vega64 a bit

[Minotaurtoo]

Ok... first off, I'm not having any trouble and I'm loving my 6900xt... but overclocking seems to be a lost cause on this reference edition card...  getting my best performance by undervolting.  I've determined that thermals are a limiting factor as anything over stock power limit at default voltage will send the hotspot straight to 110C in stress tests even with my case open and 100%fans (games usually don't pass 100C)... at default settings, hot spot temps are more subdued in stress tests hitting just over 100C and rarely go above 90C in game.... but with a small undervolt to 1130mv instead of temps dropping more, the card seems to automatically push harder hitting higher clocks.. 2480mhz max while holding 2200+ in games.  I did put a fan blowing on the backplate and that helped a little...very little... but repeatably 1-2C less than without...

 

So... am I missing something or is this just like the old Vega cards where undervolting is pretty much all you can do with a reference card.... again, I don't need the overclock, just playing around to see what I can do... so far, mine is as meh as meh can get lol.

 

side note:  ram overclocking was super easy... so easy I forgot I had done it... just slid the bar over and it worked.

I'm a complete overclocking novice, so unfortunately, even though I am also the owner of a 6900 XT, I have no insights to share with you other than to provide a link to a thread over at OCN that I've read a substantial portion of in preparation for squeezing what I can out of my own GPU.  [Official] AMD Radeon RX 6900 XT Owner's Club | Overclock.net.  You may already be fully aware of this thread.  If so, I'm sorry I was unable to be of assistance.
