Low 4090 performance in a prebuilt, how to improve?

[dlin95123]

I bought a prebuilt PC that has MSI Z690-A WiFi DDR5, i9-13900K, 4090, 64GB RAM, and 1000 Watts PSU. I ran it through Cinebench 2024 and the 4090 has a score around 30,500. The average score for 4090 should be around 34,500. I have updated all the drivers and OS. After a couple months of tuning, the GPU score is still around 31,500. I have tried GeForce Experience auto tuning and ASUS GPU Tweak III.

Any suggestions on how I can further improve it? Thanks.

Get rid of all the bloatware, all of the RGB stuff, all the antivirus and other junk that they pack into it. Better yet, wipe the whole drive or use your own and install your own copy of windows.

And use the newest driver

 

[dlin95123]

I have reinstalled Windows 11 Pro OS, updated BIOS, removed all bloatware I don't use, only Windows Defender on this PC, updated all drivers, and disabled RGB already.

I don't know much about GPUs, but that could be the difference between a 450w card and a 600w card?

Try running 3D Mark Firestrike and compare the scores against others with the same GPU/CPU.

What's the GPU temp like? Could it be throttling?

While running the GPU benchmark with Cinebench 2024, GPU temp's highs are in mid 50s C.

This is an ASUS TUF 4090. While using GeForce Experience to perform auto tune, GPU's max power consumption exceeded 600w.

There's something else going on with the OPs performance (that I have no idea what it could be), but I have a 450w card that I run at 70% (so 315w-ish) and I get well over 35k on CB2024.

Same, 340w here and score 37000 ish.

Maybe the auto overclock is hurting performance try stock?

Definitely try running 3dmark timespy/firestrike

 

[dlin95123]

I ran the basic version of Time Spy. The score is shown below.

The Cinebench 2024's 30000 ish score is from using stock 4090 setting.

Since it's a prebuilt, check if your PC has the RAM installed in the correct slots. If it has only one memory stick, buy a 32, 48 or 64 GB kit and install them on slots A2 and B2. Double check if your memory is not running at JEDEC 4800 and instead at a more reasonable level (your low-end Pro tier Z690 will be a problem here, even my high-end MEG tier one is, but you should get at least DDR5-6000 out of it), your graphics card's temperature and the general cooling on your system. See if the card is connected through a native 16-pin (12VHPWR/12V-2x6 cable) or if it's using the quad 8-pin PCIe to 16-pin converter that comes with your GPU. If the latter, ensure that all four cables are connected securely and tightly onto the converter. If your card is running off a 3x 8-pin adapter, it will be restricted to 450 watts (which is not fully adequate for RTX 4090 - such adapters are intended for the 4080).

How do my Time Spy and Fire Strike scores look?

I ran Cinebench 2024 again just now. The score is even lower than 30000. The Windows is set at "Ultimate" performance.

 

[Deleted member 223428]

Your Timespy score shows that the Intel GPU is active. I've seen lower scores when it's enabled.

I'd suggest going into the BIOS and disabling the Intel Graphics to see if your scores in both 3DMark and CM2024 improve.

It might not make a difference, but it's worth a shot maybe.

Switch to Advanced Mode (F7) after getting into the BIOS (spam DEL key while booting), choose 'Settings, Advanced, Integrated Graphics Configuration, and then set IDG Muti-Monitor to Disabled. Then choose the X in the upper right corner and choose 'save settings and exit'

 

[dlin95123]

Thanks. I tried that and Cinebench 2024 is still below 30000.

Fire Strike Score with iGPU turned off.

Any other suggestions? Thanks.

Can we get a picture of the rig in question? Maybe a power connector is loose or airflow or something.

 

[phanbuey]

Is rebar enabled?

Can you post a GPU-Z when the card is running Cinebench?

It is a Corsair Vengeance i7400 with their Corsair 4000D Airflow case. Its airflow should be pretty good. I'll check the connector later.

Rebar is enabled.. 5 minutes into Cinebench 2024:

Have you tried turning on XMP Profile 1 in the BIOS? Just brain stormin

 

[iameatingjam]

Are we sure its running on 16 pcie lanes?

 

[Solaris17]

I’m mobile but if it’s prebuilt watch the CPU temps and clock rate corresponding to said temps.

Also comparing overall score is a joke. Look at the cpu and GPU scores independently they will both be down if one of the devices isn’t pulling its weight but the one causing issues should be lower still.

I don't know enough about this area. I went to BIOS menu and did a screenshot. Please see attached file and let me know how I should proceed.

How do I check? Thanks.

Should be here in gpu_z, you might have to press that little question mark button to get an accurate reading.

 

[dlin95123]

Yes, it is x16.

Cinebench 2024's GPU test focuses only on GPU. The CPU utilization and temp were both low while doing the GPU benchmark.
