Kinda loud, memory gets hot; runs in spec
by NathanIn instances I stress out the memory, it runs 20 degrees hotter than the GPU junction when clocked 5% over stock. The fans also get impressively loud, where they can peak up at 3600RPM. To be fair to the card, it only ever got to 60% of that speed in an adequately vented case. In my case, I have a TD500 Mesh with the fans set to 70% (only 1100RPM) and that's where the card peaked at 2600RPM. When it's running at this speed, the temperature sits in the mid 60s, given about a 25c ambient temperature. As for the difference between the core junction and edge, I find that the average difference is about 5 degrees Celsius, up to 10 degrees Celsius higher temps compared to the edge of the silicone. I don't have other cards where I can get a reading for junction to edge differences, so I really can't comment if this is either good or bad, it just seems high to me, subjectively. Lastly, I will say undervolting on this card is quite impressive. In my case, I can push power from 1025 millivolts, to as little as 910 while keeping in spec. And as for the memory, I found the voltage you deliver to the card determines how far you can push the memory. I run mine 6% higher than stock when undervolting, stable, but I can have it more like 9 percent over stock if I push voltage as far as it can go. Unfortunately, you can't control the power you push to the memory independently of the core, so you have to push one to also push the other. Overall it works, runs in spec and quiet when undervolted, but at stock it's on the louder side, so consider all this when looking to buy this card. Unfortunately, I bought this at an eye watering £900, so personally I will try making some money back mining Eth. In case you're curious, it currently runs at 62-64 mega-hashes if you wish to recoup some costs of mining when you go to sleep; it's what I'm doing.
