Low GPU & CPU utilization leading to very low performance?

[BlueMihai]

I just finished my new secondary build, but I am experiencing awful performance almost on any game. My fps in games is incredibly low comparing to what I should be getting. The CPU load and GPU load never go even near 100% and just stay near something like 50% most of the time, I have 16gb of ram so that shouldn´t be an issue either.

Below are some screenshots displaying the CPU and GPU usage + FPS
Vsync is disabled in all of them, and the temperatures were fine aswell so the PC was not throttling.

  CSGO screens here.

  League of Legends I do not have screens of, but it was running 44-120fps.
  I have no idea why, but this PC was getting better fps on LoL with am AMD HD 4560

I know that my SSD is being bottlenecked by the SATA II limits, but it is better than having the SSD just gather dust on my shelf . Also, the PCI-E lane is 16x gen 1, which should not be a problem either. Linus (LinusTechTips) did something similar to this and he had very similar (yet weaker) CPU´s and a 4x Pci-e Lane, and his results were wayyy better than mine. He was getting playable framerates unlike me --> something is wrong with my PC🙁

ADDED INFO:
-Pictures of BIOS tabs and options are here. Don´t worry they are in a logical order
-RAM is 4 × Kingston 4Gt 667MHz ECC (KFJ-BX667K2/8G), and is running at 667Mhz, according to BIOS and every other program besides CPU-Z
-GPU gets its power through 2 adaptors, one is a "2x molex --> 8 pin" and the other one is a "6 pin --> 8 pin"

Stuff I have done so far:
-Set Power Options --> High performance (also changed PCI-E link State Power Management to ´off´)
-Enabled FSB Optimizations from the BIOS settings.
-Set the gpu to maximum performance from Nvidia control panel
-Tried setting the game(s) to run on "high priority" from task manager
-Disabled any overlays to see if they had a negative influence on the performance(such as Origin, steam, and RTTS overlays.)
-Running games in fullscreen instead of borderless.
-Set GPU to Prefer Maximum Performance from Nvidia control panel.
-Enabled Threaded Optimizations from Nvidia control panel.
-Uninstalled Antivirus (Kaspersky)

Those are the most important ones.
If this is a full 490 box and not just the motherboard ,let me know and I will search for the other drivers you might need.

Well I bought the Dell 490, replaced the processors (It had 2 5050´s) and got 16gb of ram for it (it had none in the beginning). I am also using the original case and PSU at the moment, I might change the case later, but I don´t think that getting a new PSU is even an option

Little confused with the Ethernet drivers, the file was .sys and not an executable. But eh, my ethernet works, so is this still needed?
Edit: restarting my system now, just incase.

Sorry I thought it was the drivers page(EXE file)
Those are the INF files which you can manually install in
Windows/System32/INF.folder
But if it is working fine for you then not necessary.

I had not forgotten about your thread.
My Daughter, her husband and the grand-kids were up for the holidays, so I have not had a lot of free computer time this last week.

Wound up playing Starcraft2 with the grandson until 1:00 am last night.
But sadly they had to drive back to south Florida today.

The chipset and storage drivers should fix most of your performance problems.
Give a game a try and see what your results are.

 

[BlueMihai]

Sounds like you had fun ^^
Anyways, I installed the ´chipset drivers´ but I am not sure if I installed the correct storage drivers, I installed the ´Intel Matrix Storage Manager´ since the others said ´raid´and I am not using raid. But with these installed, I still didn´t notice any difference in the performance :/ . I tested this on Space Engineers and Battlefront.

 

[BlueMihai]

Going to test this system with 2 PSUs just incase the CPU´s aren´t getting enough power. I will power the GPU with that, this way the CPU´s have a ridicilous 750 watts or so to use.
This is pretty much the last idea that I have 🙁 I have almost given up on this system.

 

[Unolocogringo]

Go here and follow the prompts.
It should detect your chipset ,usb' pcie,
drivers will then be prompted to download and install.

[BlueMihai]

It did not detect any new, or existing drivers :O http://i.imgur.com/lIPAkAM.png

 

[BlueMihai]

Tried the system using a 760w psu to power just the GPU, leaving the 750w psu to power the CPU´s. Using 2psus had no effect on the performance, so the voltage was not the cause to this problem.

Did some more digging.
It appears that the latest operating system supporting the x5000 chipset was vista and 7 with vista drivers.
But you can run windows 7 with vista drivers for the chipset and get good performance.

The generic drivers by Microsoft work .
But they are not chipset optimized for performance.
You need win 7 on your hardware for driver support
I run Lubuntu on mine for fulding@home. So I never encountered the windows driver problem.

I installed XP pro on it a couple years back for overclocking, monitoring and testing. Then Installed Lubuntu for F@H production, which is faster than windows production from OS overhead.

Edit.

There are some post on google about modified INF files for drivers. which work.
You can find these in google if you are set on win8 for OS.
I will not link to something I have not tried myself.

 

[BlueMihai]

I cannot install windows 7 on this computer, I tried doing that but I had to settle for windows 8.1 pro, so I will have to test those INF files, if I can find them.

 

[BlueMihai]

Okay guys, thanks for the help I appreciate it, but I´m giving up on this system since nobody seems to have a solution.
I will sell these parts and try to cut my losses.

Hello, i see that you set the power settings to high performance, but you also set cpu min and max to 100%. It seems obvious and simple, but sometimes we forget the obvious things.

Yep, I messed around with those aswell, I even tried the "core unparker" method.
