Upgraded the graphic card but...

[Zozo66]

Hello everyone,

I'm very confused and I don't know what to do, so I hope to find some answer here.

I have this prebuilt computer from HP Omen 880 with GTX  1070 and I7 7700 CPU:

https://support.hp.com/fr-fr/product/omen-by-hp-880-000-desktop-pc-series/15776604/model/17200008/do...

And I wanted to upgrade the video card, so I bought a used GTX 1080 FE from the internet, the owner tested it and told me that max temp while gaming was 82C, which is a normal temp for the Founders edition cards, so when I received the card and installed it properly (it was easy because the card has exactly the same dimensions as my GTX 1070 FE, also the new card uses one 8-pins connector as the 1070), and when testing the card it was the surprise, the performance was very low, lower than my old 1070, it is like half the performance of the GTX 1080, I don't understand why? 

Can it be the power supply not efficient? The PSU in my computer is interne 500w as stated in the computer's page, and I searched everywhere in the internet, everyone says that 500w PSU is more than enough for the GTX 1080 (and that is why I didn't buy a newer graphics card because I know that my PSU will not handle it).

When benchmarking the new card, it was like the FPS is half the full potential of the card, temperature was in the range 60-70C (not 80C as the owner told me), it feels like the card does not draw the necessary power to operate at full speed, so I'm lost, what is your opinion please?

Many thanks for reading

@Zozo66 , welcome to the Community.

I reviewed the specifications of the GTX 1080 (Couldn't find the FE.) and the minimum power requirement is a 500W PSU.  Therefore, you could be spot on with your suggestion that the PSU may be insufficient to run the it.  The PSU is the most failed component in a computer.  Your computer is 5 years old.  So, the PSU has most likely lost some of its power.

@Zozo66,

@old_geekster's observation is most definitely valid.

However, why don't you try out the following approach, as it worked great on my gaming rigs, fitted with both AMD and Nvidia graphics cards.

Btw, I do second what @old_geekster already confirmed: the 500-watt power supply unit in your OMEN by HP 880-072nf Desktop (1QZ75EA) should be sufficient to power a GTX 1080 Founders Edition and there is indeed a possibility that it may be defective.

What I would try first, is the following.

1.) First, download ONLY the GTX 1080 driver from here: Official GeForce Drivers | NVIDIA, by selecting this (French version assumed) : https://www.nvidia.com/en-us/geforce/drivers/, and your webpage should look like this:

Get the driver download file, but DO NOT install it yet.

2a.) Download the Asus GPU Tweak III overclock utility from here: https://www.asus.com/campaign/GPU-Tweak-III/us/index.php.  Same story: download, but don't install it yet.

2b.) Download the UserBenchMark software utility from here: UserBenchmark: PC Speed Test Tool - Compare Your PC

 ("Free Download"). Ditto, download, but don't install it yet.

3.) Download your monitor's driver.  For example, on the desktop I am working from right now, I got an Asus Nitro VG270UA Widescreen Gaming LCD Monitor.  Go to your monitor brand's driver download site and download your monitor's driver.  In my case, the "Extract All..." folder looks like this:

Same story: just download it and hold in reserve, because the following step will uninstall your monitor's driver -assuming it was installed in the first place.

4.) Uninstall all Nvidia drivers, and to top it off, run the freeware DDU (Display Driver Uninstaller) utility to be thorough.  Can be securely downloaded from here: Display Driver Uninstaller Download version 18.0.5.7 (guru3d.com).  Remember, if all else fails, return to the Nvidia Drivers download page, and reinstall the whole doggone driver package.  No harm done.

5.) Reboot/restart your desktop.

6a.) Install the Nvidia GTX 1080 driver.

6b.) Install your monitor's driver if a generic Microsoft monitor driver shows up: go to Device Manager, left-click on the ">" sign to the left of "Monitors", right-click on Update driver, left-click on Browse my computer for drivers, then left-click on Let me pick from a list, left-click on Have Disk, and then Browse to your downloaded (extracted) monitor driver folder where you can select your monitor's driver and (re-)install it.

7.) Install the Tweak III software package.

8.) Reboot/restart your desktop.  After 20 seconds or so, a similar twin-Tweak window should show up:

Save this default/generic GPU setting ("Add New") as "USER MODE ZERO", or something like that.

9.) Install the freeware UserBenchMark software utility and run it.  This will generate your graphics (and all other PC component's) baseline to determine if OC-ing your GTX 1080 is working or not.

From here, you can slowly "tweak up" your RTX 1080 FE's graphics performance. For example, slide the Power Target to the right by a couple of percentage points, same with the GPU Boost Clock and the Memory Clock.

Do not mess with the GPU Voltage setting.

You could increase your minimum GPU Fan Speed, where it will run at the minimum %-level you set it at, until the GPU gets hotter than the minimum level it is set for, then it will speed up beyond the %-level it was set for.

Save your new Tweak settings using a different file name ("User Mode 1, then 2, etc.).

10.)  Run UserBenchMark again. See if it doesn't crash and if your GPU's performance got better.

As you can see on this UserBenchMark graphics card performance score from one of my HP legacy desktop upgrade projects (an HP Z240 SFF), this OC tool worked great:

Repeat the tweaking-up until you are satisfied with your GPU's performance, or when you reached your GPU's safety limit.  Don't worry, you can't damage your graphics card like this, as it has built-in safety features to prevent that.

Think about this approach and see if you want to try it.  May seem a bit tedious, but that is what performance troubleshooting often looks like.

Hope this was helpful.
