RX 9000 series GPU Owners Club

If you undervolt the GPU, it will run cooler, your fans won't ramp up so much, which will result in less airflow to the VRAM. Unless you make a custom fan curve, it's not a good idea, imo.

Powercolor also has PTM7950 on their cards, and my VRAM runs at 90 ˚C under load. It's definitely not a TIM issue.
Based on the fact that everybody has their VRAM running hot on their cards, I'm starting to think that it's normal and by design.

Undervolting should also reduce heat, but if the vram is made to run over 85°C by design it's a bad design when Micron says "0C to +95C"

Sadly Hynix doesn't talk about operational temps only that they are 15-20% more energy efficient per chip compared to GDDR5

But asking GPT it do say that "Hynix GDDR6 memory is generally specified as -40°C to 95°C." but it do fail to give me the source which is annoying.

But still running about 85~86°C I wouldn't overclock really because these temps are handled better, and with a boost of 3122MHz according to GPU-Z 2.64.0 I am really happy with the performance.

Sorry for all the OT in the RX 9000 series owner club.

Just need to point out that people should look at their temps and try to control them so their cards doesn't crash or die with memory failure because they can run a but hot.

I am excited to see my summer temps if I need to add a fan to the side of my card or if it will stay the same.

Undervolting only reduces heat on the GPU, not the VRAM. A cooler GPU will result in a slower fan speed, which results in less airflow to the VRAM.

Does Micron state a hotspot or edge temperature? Which one do we see in software? My guess (based on previous gen Radeon cards) is that Micron's data is edge temp, but we see junction temp in software.

Joined just to share that I too was lucky enough to get a card. Newegg was a joke and kept crashing. I did opt to spend more because i couldnt get an MSRP model. I was aiming for a XT but settled for getting a Powercolor Red Devil 9070. Paid 659 on Amazon. I seen no MSRP models on Amazon. The only options left on Newegg were all white ones which doesnt work for my case. Or a few of the pricier models of XT. Upgraded from a 3070. Only playing at 1440 and so far the 9070 has been a decent upgrade. Did have to change my link speed from auto to 4 in order to get it to post. Vram gets hot! Even with custom fan curve.
