GPU Performance Limiters

[patrickin]

Hi guys. I've been trying to figure out what is going on with my PC for the past few weeks and I think I understand it now. Using HWINFO I can see that my GPU is actually not able to maintain a high power consumption, and I want to ask you guys this: Is this because of my PSU, or is it because of any misconfiguration? Changing the PSU would end this? 

 

Config:

 

RTX GALAX 3070

INTEL CORE I5 12400F

B660M TUF GAMING PLUS D4 ASUS

1X16 RAM TEAM GROUP 

SSD SANDISK 128GB

HD 1TB BARRACUDA

FOUR FANS (3 FRONT, 1 BACK)

CORSAIR CV650W

It's under GPU Fan 2, I don't think that represents the GPU's "power limiter".

What is the issue exactly?

[BiotechBen]

Yeah, GPU fan 2 is experiencing limits, not the actual GPU.

What workloads/games are you experiencing "unsustainable power consumption"

 

 

Would also highly recommend running your ram in 2 sticks for dual channel operation. Single channel 16gb vs dual channel 16gb is a big difference.

I think It's better to show than to say, here it is:

Oh, and it's not under GPU Fan 2, it just looks like it.

Ah this one, I remember this.

Try stress testing with furmark, see if your GPU maintained 100% usage for at least 30 mins.

Yeah it maintains, but the problem is that when I'm going to play a game (doesn't matter which one), everytime I'm on the menu my GPU usage is correct (90-96%), but as soon as I get into the game it starts oscilating, and then it becomes a bottleneck. The GPU power consumption goes down, the usage percentage lowers as well meanwhile everything about the CPU increases.

Well, then it's not the GPU that is causing issues.

Are you still using Spider-man Remastered for testing? You can't use that game if you don't have the game installed on an SSD. That game requires an SSD to perform well, believe me.

Also, the RAM? Is it still 1x16GB? No wonder the CPU is working overtime.

Oh, I'm using an SSD NVME 500GB from Kingston. It's still Spider-Man since It's the only game I had backed up and it's really CPU heavy.

Tell you what, if in unigine heaven benchmark, your GPU could be fully utilized, you could rule out GPU, CPU, and PSU issue.

I'd bet on the RAM, the CPU could not keep up with GPU because the RAM is not in dual channel therefore it is much slower.

Just tried it. Benchmark runs fine, but CPU usage is pretty low (20-30%). Maybe when the CPU usage is more demanding, it lowers the GPU? My concern is that when I'm playing a game, my PSU has to choose between MoBo, GPU and CPU altogether, making it underperform the GPU giving it less power than it actually needs. Everytime my GPU hits 100% (on menus, mostly), my power consumption is a minimum of 200W. But as soon as I enter the game, the power consumption lowers directly to half of that. The only thing I can think of that can do this, is the PSU. Or am I wrong? Is RAM capable of this?

Your PSU is not smart enough for that, only ATX 3.0 PSU is supposed to have that kind of function.

If your PSU could not handle the GPU, it will just shut down, not lowering power draw intentionally.

Besides, you have stress tested it, so it's not GPU's power issue.

Please try another game, you're using a very CPU demanding game with a very slow RAM.

I think you need to learn what RAM is.

As much as I'm embarrassed to say this after I thought you were wrong, you were indeed correct. Switching my RAM from 2100mhz to 3000mhz solved the problem. Thank you so much man, and I'm sorry I doubted you. Though it's not exactly the same memory yet (my first 16GB is 3600mhz and the newest is 3200mhz), I managed to fix it at 3000 and it solved at least 90% of the problem. Next, I'm selling my 3600mhz RAM and buying a 3200mhz, these things are expensive here lol
