My computer is having a problem and I have no idea why. Last year, I upgraded my graphics card to my PC. I now am using a crossfire setup with the Radeon HD 5830 XFX XXX Edition. At first, I felt like the crossfire setup wasn't really showing any improvements and now I know why. I noticed that my GPU usage on MSI Afterburner would show around 45% for both cards. While looking at MSI Afterburner, I noticed that all my CPU cores were a higher percentage. While playing each game certain locations would have a higher frame rate than others. If the frame rate was down, it was because of that reason. I don't really know why and I've been researching solutions for a very long time. Any help would be great!   My PC specs are:   Intel Core i5 @ 3.3GHz, 8 GB of RAM, 2 Radeon HD 5830 XFX XXX edition graphics cards, Corsair 750 watt power supply and a Gigabyte GA-Z68AP-D3(R2.0) motherboard.

I play games like Battlefield Bad Company 2, Battlefield 3, Battlefield 4, Grand Theft Auto 4, CS:GO and Call of Duty. I understand that Battlefield used a very high CPU percentage, but I've noticed this problem with Grand Theft Auto 4 as well. It's with almost every game I play.

I know this might sound stupid, but under the amd control panel are both showing up properly (if so is crossfire mode checked?)? Is the crossfire cable seated properly/undamaged? Still even then the one gpu's load should still be ramping up so its strange. :/

ah ha

 

look at your board model

 

PCI-E

 

  1. 1 x PCI Express x16 slot, running at x16 (PCIEX16)
    * For optimum performance, if only one PCI Express graphics card is to be installed, be sure to install it in the PCIEX16 slot.
  2. 1 x PCI Express x16 slot, running at x4 (PCIEX4)
    * The PCIEX4 slot shares bandwidth with the PCIEX1_2 and PCIEX1_3 slots. When the PCIEX1_2 slot or the PCIEX1_3 slot is populated, the PCIEX4 slot will operate at up to x1 mode.
  3. 3 x PCI Express x1 slots
    (All PCI Express slots conform to PCI Express 2.0 standard.)
  4. 2 x PCI slots

 

the second slot is running at 4x speeds and its PCI-E ver 2.0

 

so it really slow!!!

 

 

the second GPU is getting choked and affects the whole setup

Budget? Uses? Currency? Location? Operating System? Peripherals? Monitor? Use PCPartPicker wherever possible.

Does this mean it is time for a new motherboard?

yes you need at least a board which use pci-e 3.0 and supports multi gpu

That's so funny. The box says that it "supports" crossfire. I've been doing some research and I came with that conclusion, but I didn't want to believe it. Thanks a lot for the help! Any suggestions on a new board that isn't very expensive?

Sorry im late to reply! Seems like everyone else helped out! What we need to know is what version of the core i5 you have. You can go under system specs or device manager to find out what version of processor. 

We need to know that before recommending motherboards.

It's really not about the motherboard. You should never go for multi gpu solutions, they always have something to go wrong. In this case, running a card at 4x and psi-e 2.0 won't change mucg performance wise. Be sure to have updated driver and xfire profiles installed.

 

Also, don't go all nuts because cpu is at 100% and gpu's around50 or whatever. Doesn't always mean a real/punishing bottleneck. Some games are simply too damn cpu based. 

 

I don't know but my guess is that you have some issues on that xfrire because of software and not rly hardware. check if your games have issues with xfire, update them if needed, check drivers and profiles!

I feel that getting another motherboard is a much better solution. Everything is already up to date. An i5 running at 100% usage while playing certain games doesn't make too much sense to me. I guess that will probably happen, but both GPUs having a 40 or 50 percent usage? That is just nuts and it must be time to get a new motherboard.

i have a 4670k at 4.4 and a 280x. Alot of game i play get my cpu to 100% and gpu to around 40-50%. Your gpu's are a bit older, true, but 2 of them paired make it kinda a strong build. 

 

Most games with some strong online component such mmorpg's and shooters such as BF are heavy on the cpu but not the gpu. It's like this for tera maxed out, wow maxed out, bf (even tho bf is more gpu bound) and a few other titles i can't even remember. My guess is that if you change mobo you will be having the same "issue".

 

If u rly want to, i would recommend http://www.asrock.com/mb/Intel/Z77%20Extreme4/. Don't quote me on this, but i've heard good things about this generation asrock extremes. Also asus mobos were rly good at the z77 times.
