3080 Massively Underperforming

[_pfd]

My setup is:

• CPU: Intel Core i9-9900K 3.6 GHz 8-Core
• Motherboard: Asus PRIME Z390-A
• Memory: Corsair Vengeance LPX 32 GB (2 x 16 GB) DDR4-3200 CL16
• Video Card: Gigabyte TURBO GeForce RTX 3080 10GB Video Card
• Power Supply: Corsair RM750 750 W 80+ Gold

When I do a 3DMark timespy test, it scores under half of what it should (7,812 vs the average of 16,088 with my same specs):

I've tried a fresh driver install, the case is ventilated, the PSU should be more than enough... help?

Whats the CPU cooler? Is it throttling at all?

Cooler Master Hyper H411R, and it's getting high temps but not over 90, same with the GPU temp.

Not sure that is nearly enough to properly cool it as its a 3/4 heatpipe cooler o.o Id probably buy a Thermalright Phantom Spirit and see if that significantly helps thermals.

 

GPU is gonna need to be run with a much higher fan speed due to hits cooler.

 

Other then that youll have to see if you are in the proper power modes and such. NVIDIA control panel and changing those settings and your pc power settings to high performance.

 

Also make sure there are no background tasks.

Power settings don't seem to be changeable, I'll look into the thermals, but I'm also thinking of making the jump to AM5 with a 7800x3d at some point in the near future, so I probably won't grab a new cooler. I'm still confused as to why my score is half of the average, but thanks.

that's both way too hot for your components... just because they don't outright break doesn't mean they'll perform at their best  - while at the same time fighting for dear life...

 

I would suggest investing in better cooling equipment and understanding of aerodynamics,  a very interesting subject!  (well its my favorite) 

 

ps: just to be clear 70c should be max for expected performance, lower is better obviously!

same with GPU temp? what's a hotspot temp on GPU then?

a weird myth,  ive always had worse performance with that mode, you need normal/balanced for best performance,  especially if your already struggling with temps...

Temperatures themselves don't mean all that much. Could you check both your GPUs and CPUs frequency while running the test? If they are running at 90C at max speed, that isn't really a problem.

Checking now with 3dmark, idle is at 74.8

A HWiNFO log captured during the benchmark would tell the story. Those screenshots seem to show a GPU clock speed average of 700 some megahertz. Significantly lower than it should be.

I have both open, do I just run the test and then save report on hwinfo?

Did a test, a few things stand out to me:

• Resizable bar - that should be enabled, right?
• Graphics processor clock - currently reading as 375MHz??? That's wrong, right?

Otherwise:

stayed around 88 degrees under load, with a hotspot temp of 105

GPU clock jumped between 500MHz and 1500MHz, what's up with that???

That is just HWiNFO's system report.

He was asking for the temperature / voltage / current /power monitoring log - is from the Sensor menu / tab.

As in the log from THIS:

Spoiler

 

GPU Hotspot temperature of 105*C and GPU temperature of ~88*C is pretty high.

In your previous 3DMark screenshots is says the CPU temperature is averaging at 89*C, so some of the Cores are hitting 90*C+.

Those temperatures will start to pull the frequency down, for both the GPU and CPU.

 

What case / chassis are you using, and what is the fan(s) setup?

 

RTX 3080 should boost to around 1700 ~ 1800 MHz on the GPU Core. That is, assuming temperature is in check.

Once temperatures starts to climb, it will drop.

Looking at the GPU frequency chart from 3D Mark, it STARTS high, looks like around ~1700 MHz....but it quickly drops down to UNDER 1000 MHz.

 

CPU seems to be holding constant at 4.8 GHz in your above screenshot, which seems normal.

How is your CPU temperature sitting at below 70*C, when it was hitting 89*C+ in the previous run...?

That Cooler Master cooler is not going to hold up when the i9-9900K is trying to Boost up to as fast as possible, for as long as possible.

Latest Bios? Running XMP?

[podkall]

how old is that 3080?

Doing that now, will report shortly

The case is... the DeepCool Tesseract, aka the cheapest case 13 year old me could buy. To be truthful, this PC never really got a complete overhaul, just upgraded bit by bit over many years. Hence the hard drive and disk reader that are still hanging on.

XMP, yes, BIOS, second from latest, changelog says the last was a security update but I should do that too.

Heading towards 4 years.

[podkall]

That card looks quite thin, is it this version?

might be time to re-paste, 4 years is reasonable amount of time for it to dry up or vaporize or both

Is that a Gigabyte RTX 3080 Turbo (e.g. the Blower style cooler)?

That cooler will run warmer than the open-style cooler, and even possibly the Founder's Edition (e.g. nVidia reference) cooler.

Airflow to the RTX 3080 is pretty bad.

 

ALSO, the PSU fan DOES NOT blow up, it SUCKS in and out the back.

The case has ventilation on the bottom of the case - flip the PSU so the fan faces down.

 

Your top fans appear to be NOT blowing in. They look like are sucking OUT.

The fan hubs are facing into the case = air is blowing up and out the top.

Probably a good idea to double check the front fan as well, and make sure it's ACTUALLY blowing air in, and not sucking air out.

So it looks like, right now, ALL your fans (that are visible) are set to exhaust (e.g. suck air OUT of the case)...and NO intake fans.

That WILL affect temperatures....

 

How much of a temperature difference if you run 3DMark again WITH the case side panel OFF?

Just at the top here, thanks for all the help yall, really appreciate it :)))

 

HWInfo CSV attached, here is the summary (tell me if you want to see any of the collapsed stuff):

Sounds good, thermal paste recommendations?

How could I improve it? Happy to buy a new case if need be.

Not much difference, the test I'm posting was done with panel on, panel off was about 1 degree cooler.

You're 100% right, so I should flip my PSU, and flip top fans to intake? Any other changes you would make?

 

Edit: confirmed front fan IS intaking, so that's the only intake.

HWInfo CSV attached, here is the summary (tell me if you want to see any of the collapsed stuff):

 

Where did the CSV go? 

 

Both CPU and CPU temperatures are pretty hot.

CPU Cores hitting 90*C and package 92*C.

GPU hotspot is hitting basically the max ~105*C, GPU Memory is a 96*C, and GPU 91*C.
 

"GPU Performance Limiters - Yes" RTX 3080 is thermal throttling.

 

Think about re-doing the thermal paste on the RTX 3080, and blowing any dust out of the GPU cooler.

 

[adm0n]

Since the GPU idle is also incredibly high, I'd definitely repaste that card . There might even be a mounting issue with the GPU cooler.
