Getting way higher stable vram overclocks though worse score in benchmarks

[Masterbeter]

I recently built my first computer and decided to overclock it using msi afterburner. after a couple hours of messing around i found i was getting a stable over clock of +160 to the core clock and + 650 to the memory with a voltage increase of 23%. I was using heaven benchmark set to extreme at 1440p resolution on full screen and got a score of 2060 on stock settings and a score of 2239 with the overclock. all was well and good till I accidentally entered the value of 1600 instead of 160 to my core clock and black screened. Because I had msi afterburner was set to open on start up and apply my over clock I kept crashing so I opened windows in safe mode and uninstalled msi afterburner then reinstalled it once i was out of safe mode. Again all was well and good though after that i found that i could raise my memory over clock to +1100 and my core clock to +160 with a voltage increase of 20% without getting any crashes stutters or artifacts in haven benchmark  with the same settings or various games such as assigns creed odyssey, rainbow six siege and gta v. though when I bench marked it I was only getting a score of 2192 furthermore when i brought the values back down to stock i got a score of 1971. I've tried reinstalling my nvidia drivers and reinstalling haven though no luck getting back to the values i had before. i read that sometimes when memory is overclocked to values that high it can give worse performance instead of crashing or artifacting so i tried various other values like 1000 900 800 ect though they all got worse scores then the 1100 mghz overclock.

 

If anyone could help explain whats going on and/or show me how to fix this it would be much appreciated

I sometimes get strange readings with MSI afterburner with RTX cards. Now I use Pression X1 overclocking and Afterburner for monitoring. 

 

Also Vram on these cards heat up over time and can affect a score.  To see this reboot your computer and then run heaven in a widow. With afterburner or Precision X1 note at what temperatures the GPU clocks down. On my 2080 ti it is about 54c, 64c, 74c and 84c. If I run the test again after the card heats up the numbers shift down. Only with the vram at a constant temperature can you get constant results. 

 

At some point your overclock on the vram will downclock your card so higher means the same or lower. With my FTW3 Ultra this occurs at around 86c.  I can use + 1100(8100mhz) and stay below that temperature while benching at 1080p but not at 1440p. So for gaming I use + 800(7800mhz) since I do it longer and heat will build up over time.  

Here is what it looks like.

At 1440p there is virtually no gain since Vram temps become a factor.

 

 

At 1080p vram temps stay cool so there is gain from the extra overclock.

   

With cards the don't have extreme cooling solutions this is amplified.
