Solved EVGA GTX 760 SC Not Consistent

Specs: Windows 8.1
I'm not getting frame rates that I would like with my new EVGA GTX 760 SC. In Battlfield 3 there are times that it dips down to 40 when I'm looking at something somewhat intensive in the game. Even at low settings it will go below 60. And with older games like Red Faction Guerrilla it will go down to 45. I assumed with this card that I'd be hovering above 60 most of the time, especially with older games. I've been into the Nvidia control panel and tinkered with the settings, but it doesn't help much. I don't see that overclocking would be necessary. I'm running at 1080p. My system stays relatively cool. My drivers are up to date.

Is this normal? I don't see how this would be possible, but could I be bottle-necking with my CPU?

That sounds like a telltale of a BN. When doing easy calculations (sky) it uses more GPU power just because it's easy to do, but when doing heavy stuff it loses processing time due to something else slowing it down, in this case the CPU preprocessing.

It's probably OK, just as long as you don't start getting the infamous Lag Spike during intense renderings (read: RPG explosion) that kills the gameplay pretty fast. Unless you happen to be that type where every single FPS matters, and you want full out max everything. In that case I'd say you would need to go up to maybe something like a FX-8320.

EDIT: AMD's 'Turbo Core' tech auto-overclocks the core based on usage, often disabling some cores while cranking the clock on the other ones much higher due to the extra thermal and electrical headroom. Maybe this is disabling some cores and forcing the remaining cores to take up more of the GPU load? If you can, go into your BIOS and disable this. It may or may not help. and also maybe start thinking about OC'ing your processor a little bit if you feel safe with it?

Win8 64-bit? DDR3-1866? You could have done much better on your motherboard choice, the AMD 900 series chipsets were designed for the FX series CPUs. Did you install all the latest drivers? Windows properly tweaked, especially the startup entries? Lightweight AV software? Did you try dialing down the game settings a bit?

DDR3 1333, Windows 8.1 64-but

The stock of the motherboard is DDR3 1066, but it can be OC'd 1333 and over, and it already is. My drivers are updated, and I have barely anything on start-up. Is there anything I should do in my BIOS? Is there a good way to optimize my cpu or gpu usage?

I'm dialing down BF3 to low and still getting below 60 at times.

I'm still able to return my ram and motherboard. I'm not sure why my specs wouldn't be fine for gaming, so could you explain? What are the cheapest but most reliable parts you'd recommend?

"I'm running at 1080p"

There's the game resolution & the monitor resolution. The monitor resolution should not be changed but if the game resolution is 1080p, try lowering it to 720p.

You shouldn't be bottlenecking, that CPU should have the power to hit it off fine. It would almost sound like a heating issue, but you say your system runs "relatively cool".... Use a program like HWMonitor or Speedfan to check your temps while gaming, just guessing by feeling the parts is never accurate or a good idea to be putting for fingers inside of an active case...

At any rate, I agree with Riider, you could have done MUCH better on the mobo unless you were under some budget constraints. You should have at least gotten 1600 if not 1866 RAM for gaming.

According the the EVGA site, that card needs a MINIMUM of 500 W PSU. Generally when they say that I'd go with 600W or 700W to be safe. But that shouldn't be an issue...

I guess I will return my ram for 1600, although it won't make much of a difference. I'm getting 32 fps ultra on Heaven Unigine. But I figured with this card I wouldn't be getting down to the 30's on BF3. As for testing temps, I used HWMonitor and I didn't go in and physically touch the parts.

GPU maxes 63 celsius
CPU maxes 38 celsius

How are these?

Bump.

Could really use some help here...

"I guess I will return my ram for 1600"

To do that you will have to replace your motherboard too. Your motherboard only supports 1333 RAM at O.C, so that's probably all the speed you'll get unless you change it out too. You can only push them so far.

As for those temps, if those are under full load they are doing great. CPU temps are beyond superb, might I ask what cooler you're using?

EDIT: After looking, it says that your motherboard supports PCI-e 2.0 at x16, but the GPU is a PCI-e 3.0 at x16. As far as I know, that's a bit of an oversight. Might it be possible that your motherboard is the limiting factor here?

I am using the stock heat sink. It may be the two stock fans of my Fractal Design Define Mini case that are generating adequate cooling, as I am running them at full speed. I also replaced the stock thermal paste with arctic silver 5. Lastly my room temp stays under 72 F
EDIT: Well, now I'm getting 44 celsius maxed, but still pretty cool.

SO, are you telling me that my motherboard is actually downgrading the performance that my card is capable of!? That is definitely something I overlooked...

EDIT: So I did a quick search, and my card shouldn't exceed 2.0 bandwidths. However, I'm seeing mixed answers.

All is well now... Had to configure things in my BIOS.

EDIT: Actually I'm still getting low fps.

For reference, I'm getting down to 30 fps on Battlefield 3 close quarters maps. When I'm in the spawn screen and in the background there is a still of what's going on in the whole map, it'll drop down to 25 fps. Even if I put my resolution and the settings down to the lowest, it still goes below 60!! This is extremely frustrating...

Could it be a cpu problem? My temps don't go high at all, but perhaps the cpu itself is faulty?

Or maybe I could change something in my BIOS?

Actually, after some more digging I've seen some situations where even an R9 270X is getting BN'ed by the FX-6350. I still don't think that this should really be much of an issue in your case, but it's still a possibility.

Make sure to disable V-Sync or any FPS limits to maximize your FPS. Run this program: http://www.ozone3d.net/gpushark/ and see what your GPU utilization is while running the game. If it's less than ~70-75%, then you're most likely getting a BN on that CPU.

I'm getting better frames because I uninstalled an incompatible version of Norton, but my frames are still down in the 40s.

With that program I got a max of 94% usage, but it's usually less that 75%. Like at around 50%. However, I have VSYNC on.

EDIT: Turned VSYNC off. Whenever I look at the sky (unintensive), FPS will go into the hundreds and my GPU usage will go over 80%. When I look at something intensive my GPU usage will go down to around 40-50% and the FPS will go down to 45. I think that might be okay with my specs though, after seeing a few videos on youtube with the same specs.

But If that's bottle necking, I seriously don't know what to do. This CPU should be more than adequate.

Re-installed Windows and everything is fine now. Guess it was the remnants of Norton still on there. Now I can actually enjoy this thing!!

Thanks for the assistance.
