bdaryI don't know if there's any guides around, but here's the basics... The power target is a limit. It allows for a little extra power to be used over the stock 100%. It's always better if your card doesn't hit that limit as then you won't be limited by power. You will see different power usage numbers depending on the load on your GPU. Some games/benches will put higher loads on the card then others. If you slide the voltage slider to max, it allows the card to go up to 1.093v. Otherwise, the typical voltage I see when the slider is left at 0 is 1.040 to 1.053v. On the core clock, the increments are 15MHz. Start with OC'ing the core in 15, 30, 45MHz increments etc., testing in between for stability. Once you have that dialed in, do the same on the memory. With the memory you can increase in bigger steps like 50, 100, 150MHz etc... Testing in between increases.
bp717855c is high for a water cooled card, that will limit you some as the card will clock down the warmer it gets. If you can keep it under 40 you’ll maintain your higher clock speed longer. GDDR6 memory can be tricky as it includes error checking. You can set the speed past the point in which errors will be present but there won’t be any visual indication of this. No artifacts or the like, but performance won’t scale with the increase. Most RTX cards should be able to do +500 on the memory without a problem. Good cards that use Micron memory may hit +750 or +1000. Cards that use Samsung memory will do +1200 or +1400.
bp7178I doubt you will see better than 55c on long sessions with a HC card even after re-applying TIM. Some people have posted that they got better results, but I haven’t saw any long term testing. With the higher (+.75mm over EK blocks) gap between the block and GPU the type of thermal paste starts to become a factor more so than normal. Thermal Grizzly Kryo almost becomes runny at high temps, and this will be exacerbated by vertical mountings. I have saw TK K paste run down and pool near the PCIe connector. The number you’re adding to the GPU, say +100 depends on the base and boost clocks of the card. That +100 may result in a 2190 or a 2000 depending on who you’re talking too. So look for the actual frequency when comparing. The best thing is to install a temp sensor so you can monitor the temp of the water. You can compare that to your ambient and see how you are doing. A water temp which is 10-15c of ambient is great.
bp7178Removing any mesh panels in those top vents will help, as will removing any filters. If dust is a concern, just blow out the case from time to time.
