Title: My curious case on GPUs with no Vram temp
Post by: Outhue on April 10, 2022, 12:13:03 PM
Just out of my curiosity, every GPU has VRAM right? What do you think will happen if we can all trace our GPU VRAM temp today? I'm not talking about 3070ti and 3080s I'm talking about those gpus that only display norm temp not the Vram temp, you that your gpu is displaying 68-70C on norm temp I wonder what the Vram temp would be... Just because we cant see doesn't mean its not hurting, I could be wrong thats why I create this topic, let's have some conversations.

Every GPU has vram, right  ;)

In the past we didn't have vram temps because we didn't need  :D , now it's more common specially after mining

Usually the GPUs have:
AMD - 3 sensors
Nvidia - can come with 1 sensor, 2 or 3, depends on the model

Special edition GPUs or high end GPUs can have more sensors, like this EVGA:

But this is not the standard, to put more sensors manufacturers need to charge more for the card



This concept of "norm" like you said, is not the right thing to say, we can say it depends where the sensor is, so it's common to have on the gpu and memory (vram)

This.

Nvidia got very aggressive with gddr6x, amd has been implementing memory sensors for a long time in their gpus, even polaris aka rx 480 has. A better definition would be, nvidia and amd giving devs code to check their memory temp sensors, nvidia is lagging behind amd in this regard. Teamredminer can check the memory temperature of your amd gpu.

I used my 3070ti to mine ETH for a month without knowing that my memory temp is on 100 degrees already until the hiveOS update introduced mem temp on their dashboard, how could I have known when the GPU temp was at 47C mining ETH 60MH, I thought its working in its best shape yet, I wish every nvidia GPUs have mem temp readable.

Mem Temp reading is not needed for GDDR6 models, so this GPUs dont need a sensor for the VRAM.

Almost all GDDR6x video cards need thermalpads change, the original are too bad, this is why i stop buying Nvidia cards.

So newer AMD graphic cards comes with higher end thermal pads and pastes? I don't believe that because those RX6800XT have high mem temp issues too, its normal for mid to low class thermal pads wear out in few months of mining, they are doing intense work mining 24/7.

I'd say all, more than 90c is not acceptable for 24/7.

Hope this helps, some of my RTX 3060 Ti has memory temperature readouts. About 82-86c for the sample of three cards that had the readout with fans running at 75% and core temp 55-56c.

Also, please note, the system above is sitting on the top-rack above this system below.. so the temperatures will be higher. The system below has RTX 3080s (memory temp in the 80-90s) and a few 3060 Tis (Core temp: 44c, memory temp 78c)

So I guess to answer OP's question, if your core temp is 68-70c, you can assume your memory temp is way too high for a RTX 3060Ti/3070 card with regular GDDR6.

Just tell me what AMD card use GDDR6x and the memory working at 106C-110C that make the GPU throttle, name me just 1.

This proves that every thing has their own advantages and disadvantages

1. NVIDIA

The better driver supports.
Less heat generation.
Worse cooling pads.

2. AMD

Worst driver supports .
High heat generation.
Better components for cooling.

You can't expect everything to be perfect out of the box.
