My 3090 FE routinely runs above 90C just doing light gaming like playing WoW on 1440p. 00 SGD. It is speculated that mem junction temp is the temperature of the highest ram chip (igors lab). The originally measured 104 °C in the gaming loop are high and would probably even increase if the ambient temperature of the card increases significantly. Everything else about this Turbo card is the same as the standard RTX 3090, including 24GB of GDDR6X memory and 10,496 CUDA cores. x or thereabouts already installed. Same case, same components, only changed GPUs. 42 and higher - it's free) and check your NVIDIA GPU's GPU Memory Junction Temperature - cards like the 3090 can easily hit 105 C and higher. On the left image you can see the idle video memory temp we see on an ASUS EKWB GeForce RTX 3090 GPU and on the right the temperature of the video memory after we run PhoenixMiner with the tweaked RTX 3090 in order to give us 120 MHS hashrate for Ethereum mining. Best of all? This OLED is integrated into the PCB, meaning that no matter the graphics card orientation or the cooler being used, the display can be easily read. So if you are not experiencing any shutdowns or reduced performance in the game, your GPU is working under safe temperatures according to manufacturers. 7 Tensor TFLOPs when using the Sparsity feature for AI inference At this point we have to scroll through the settings until we reach the section of our GPU, where we will have to locate a value called “GPU Memory Junction Temperature”, which specifies the temperature of the GDDR6X VRAM, which is what we’re really interested in. 1 GHz clock. I am guessing dell 3080 / 3090 work best with 1. In the following table, all the values are for T JUNCTION temperature. We A slightly different idea for 3090 memory junction temp issues So I bought the new Gelid thermal pads and have them on the way. Many linux users are pretty concern about the memory temps like me but we haven't found any linux software can readout this junction temp yet. Thus the card should offer a very similar performance to RTX 3090, but it will all depend on the clock speeds and enforced TDP (earlier reports have suggested it will be 320W like RTX 3080). The front facing cooler is up to the job though. The voltage produced by a thermocouple junction is very small, typically only a few millivolts. We get 36 degrees idle temperature, but when mining it bumps up to 92 degrees Celsius and this is a water-cooled GPU with the GPU temp going just about to 50 C under load. It dropped 10 degrees C for memory junction temperature after new pads. 70°C – 75°C: Better hashrate! This is the optimal temperature that is acceptable for newer generation graphic cards. x, whereas when I tried to apply it, it detected a higher version 94. The RTX 3090 is also rocking 24GB of GDDR6X video memory on a 384-bit bus, which makes for 936 GB/s of memory bandwidth – that's nearly a terabyte of data every second. Even though AMD has solved the determination of T junction (“hotspot temperature”) differently with the new Radeon graphics cards (Navi21) and measures and calculates much more widely, it is precisely this temperature that is the linchpin for telemetry. It was a similar case with Navi when AMD exposed the Memory Junction temperature to users. 2-2280 NVME SSD $158. Discussion of mining the cryptocurrency Ethereum. The average clock and memory clock was running very low, probably due to the high temps. 5mm to 2. All these videos, posts, and pictures showing decreases of 20, 30, or more on the junction temperature. but I guess that's to be expected considering 2080Ti is only 250W TDP(for reference model) and 3090 is 350W TDP(for reference model), and all the AIB 3090's pretty much got identical sized cooler they used on AIB 2080Ti models and 3090's also got 24GB GDDR6X VRAM(double sided and also runs very hot apparently). However, Asus is using its GPU Tweak software to automatically It started with the RTX 3090 as I was able to get it for MSRP, I decided to build a computer around it without salvaging parts from the old PC with the exception of the 850W PSU. Checking the backplate of the water-cooled RTX 3090 with a FLIR thermal camera showed that at stock settings when mining you get around 72. 02. NVIDIA calls this its “flow-through” cooling solution and claims it delivers a 20C drop in temperature for the RTX 3080 (versus the 2080) and a 30C drop in GPU temps for the RTX 3090 (versus These numbers depend on the GPU, but most of the time the maximum temperature a Nvidia GPU can run at is around the 95-100 Celsius mark (~200-210 Fahrenheit). 5" 1920x1080 240 Hz Junction Temperature is the maximum temperature allowed at the processor die.
