Overwatch, big FPS drops

[Deuteronomy93]

Hi All

 

Hoping someone can help!

 

I'm having some issues with my Area 51m and no this doesn't have anything to do with thermals.

 

I've largely fixed the issue with the thermals and massive downclocks by undervolting and overclocking the CPU and GPU.

 

I'm attaching an HWinfo64 log of a typical game, I was getting up to 300 FPS in Overwatch on low-mid settings however now I'm often getting 210 FPS with stutters and dropping down to 60/70 but most often around 140-160 etc.

 

Things look normal on the GPU side in the charts with voltages and clocks, the temperature maxed out at 50 degrees (max fan speed but Sennheiser headphones sort that out!) so I'm at a bit of a loss as to why this is happening. The CPU I believe looks ok but any help on what could be the issue would be really appreciated!

 

To confirm general settings etc before looking at logs:

• RTX 2080
  • 1920mhz Core clock, this has a nice and even voltage curve where I'll max out at this clock to avoid too much power/heat going in, this was the best and most consistently high result
  • 7200mhz Memory clock, this was the best and most consistently high result
  • Repasted with Thermal Grizzly paste (not LM)
• 9700K
  • Same issue happens without undervolt/overclock.
  • -100.6mV undervolt, I have tried from around 80-110, this was the best and most consistently high result
  • 5.1 all Core overclock, I have tried 4.7, 4.8, 4.9, 5.0, this was the best and most consistently high result
  • Repasted with Thermal Grizzly paste (not LM)
• 16GB (2x 8GB) DDR4 at 2400MHz (The only speed they supported at the time weirdly)
• 512GB RAID0 (2x 256GB PCIe M.2 SSDs)

 

I've really tried to ensure that the components are staying cool but still getting an adequate amount of power.

 

I believe the changes I made should be fine based on:

• Other people's results
• My own testing
• The fact that when it is working, the temperatures are comparible/everything I believe looks similar (at least on surface level)

 

Please let me know your thoughts!

Best regards
