  1. Here's a link to the full res version of the desktop wallpaper: https://imgur.com/gallery/3Wk2mOk
  2. Found the I2C header pads. No need to solder wires really close to the VRM controllers. PCB picture from: https://www.techpowerup.com/review/powercolor-radeon-rx-6800-xt-red-devil/3.html In other news the mem cap mod is not as effective as it intially seemed. It's not +50MHz more like +20MHz.
  3. Stock (1.35V) Vmem. The stock cap configuration is kinda shit. Just compare the back of a 2080 Super to a 6900XT
  4. I added 4x4.7 uF 0402 MLCCs per VRAM chip and 3x470 uF to the Vmem VRM. Card now seems to scale all the way to 2200 mem. Starts to lose performance at 2220. Anyone else want to test?
  5. All the voltage rails I can find on my card. IDK why there's 2 1.8V rails. The BIOS chips probably run on 1.8V and the GDDR6 obviously has a 1.8V VPP but that could be done with 1 reg not 2. the 0.75V and 1.8V rails use MP8633 regulators. https://www.monolithicpower.com/en/documentview/productdocument/index/version/2/document_type/Datasheet/lang/en/sku/MPQ8633A/document_id/1052/
  6. I tried it. It helps a little but seems to make core stability slightly worse.
  7. I run like 2450 min clock with 2820 max clock. With 2600min and 2820max the scores are actually worse. Also if you set min clock too low that's also bad. IMO just running the 2 in lock step is wrong.
  8. So far my exp with the 6900XT Red Devil Ultimate(XTXH core) on air is: Raising min clock too much tanks both FPS and stability. Mem clock significantly above 2150 causes performance loss. Major artifacting and black screens at 2250. (I'd guess this can clear up with more Vmem, VDDCI or VSOC depending on where in the chain the errors are coming from) Even with the 1.2V limit you'll want at least a 410W power limit for FSE. So far I've just been using a power play table with a 511W power limit based on the 6900XT OCF BIOS.
  9. you really need to get and use PScheck if you want to improve your valids. Also a board with 1core per CU mode(old ASUS, any Gigabyte/Asrock).
  10. I agree that if you want a all core valid ranking it should just be separate from the existing CPU-z valids.
  11. Apparently CPU-z wasn't bin to win enough as is. So next are we gonna ban maxmem for memory frequency valids and require all mem channels instead of just 1?
