Mine was Sept 2017. It is a liquid card. Air cards are maxing themselves out around 1.6Ghz due to thermals. Air cards converted to liquid.. most will do 1.7Ghz pretty easily.

I use the manual setting. Not the % slider.

Thanks, will decipher on how to do that lol

Where it says "Frequency %" click it.. should convert to manual.

Must be rich to mess around LM on a premium GPU

You don't have to be rich. You can also just be foolish.

You confuse rich with reckless. Seriously though...I took the appropriate precautions. Not a total idgit.

Or that.

Do you use the normal mode or switch to the turbo ? I need to try this with my card although not sure when. I need to ship my computer over since I've moved to another country and God knows when that's gonna happen

i use this, no paste for me ever again, and no mess. and it cools about 1-2 celsius better than kryonaut. conductonaut is still better but not worth the risk to me.

Now you've peeked my interest - I know TG have a new thermal pad coming out for GPU and CPU applications.. might have to have a peek

Update: After fiddling with lots of stuff like voltage, fan curve etc, all that I could achieve was pushing the core clockspeed to 1,800MHz so it could stay at 1735-1750, while using 327W with a Vcore of 1225. Going higher would yield a black screen even with the maximum Vcore of 1250 (Can't go any higher with the Wattman). But then if I drop the clockspeed to default 1750 with the voltage of 1150, then it would run between 1700-1730 while using 267W of power. So definitively not worth the additional 25-30MHz while using more than 50W and higher fan noise. I think that either I have a low quality ASIC, or since I bought it on late November of 2017, probably would need a repaste. Any suggestions? The Thermal Grizzly sounds like a great alternative but have you guys heard about the Hitachi HM03 ?

Ive seen the coverage of it on the Radeon VII, know TG have a similar product too which may be more readily available

Did you repaste the card (the Vega64) eventually ? I have an old one also Sapphire Nitro+ LE and even with 100% power and 1.150 - 1.200 mV it still doesnt clock higher than 1615-1620 MHz ... is the HotSpot temp throttling me ? Should I replace the thermal paste ?

Thanks in advance guys.

i used a X pattern across the die with kryonaut

It's like I always tell my wife... could be worse I could still be tinkering with cars tube of paste certainly cheaper than a ring of rubber.

Not sure about that: https://www.amazon.com/Thermal-Past...t=&hvlocphy=9011831&hvtargid=pla-805364003932

Seems the rings of rubber are cheaper - just by the thickness of skin.

This might be a little off topic but does anyone have a detailed tutorial (preferably video) on how to apply thermal paste to reduce hotspot temperature? I watched the video in OP but it wasn't that clear

The Hot spot is “under“ the die so just doing a proper job is the best you can do.
