It seems that the HWiNFO tool is no longer the only software that allows you to check the GDDR6X video memory temperature on Nvidia RTX 3080 and RTX 3090 GPUs. The latest TechPowerUp GPU-Z 2.37.0 apparently also supports the display of the temperature of the hot GDDR6X memory chips and not only that, but also features support and reports the GPU Hot Spot temperature as well. It is interesting to note however that these two features apparently were left unannounced as getting added in the changelog of the latest version that has been released about two weeks ago. Frankly it was by luck that we found out that the GDDR6X Memory Operating Temperature and Hot Spot monitoring support has been introduced in the latest GPU-Z software.
GPU-Z v2.37.0 Changelog:
– Added memory vendor detection on Navi 1x and Navi 2x
– Added workaround for NVIDIA Ampere PCIe hardware bug
– Added filter to avoid misreadings on EVGA iCX
– Fixed fake detection for some GT218 variants
– Improved Russian translation
– Added preliminary support for Radeon RX 6700 and RX 6600 Series
– Added support for NVIDIA GeForce RTX 3060, RTX 3080 Mobile, RTX 3070 Mobile, RTX 3060 Mobile, RTX A6000, A40, A100-SXM4-40GB, Drive PX2, P106M, Quadro K510M, modded Quadro K6000
– Added support for additional variants of NVIDIA GTX 1650 Max-Q, Quadro P1000, GTX 650, GT 430
– Added support for AMD Cezanne, Radeon Pro V520, R9 290X ES, Barco MXRT 2600
– Added support for Intel Comet Lake Graphics (Celeron 5205U and i7-10810U)
– Added vendor detection for Yeston
The comparison between the values reported by the two useful tools is inevitable and they report the values for GPU Temperature, GPU Hot Spot and Memory Temperature very close to each other. So, using either of the two programs will be fine in order to get you the needed information. Going for either GPU-Z or HWiNFO will provide you with the data you need to know how hot your GPU and video memory is on GeForce RTX 3080 and RTX 3090 video cards when used for mining. Ethereum mining on these particular GPUs is very popular due to the high mining hashrate they provide, but it also comes at the cost of high operating temperature for the memory chips especially. Keeping an eye on the GDDR6X memory temperatures and the GPU Hot Spots can be useful in detecting possible issues you might have with proper cooling of your mining video cards.
