Motherboard hurting average FPS?

post #1 of 6
Thread Starter 
Okay the story is I just upgraded my system from an AMD X6 system to my sig rig and since the upgrade I have seen decreased performance in games, normally around 10FPS drops in anything GPU intensive Aswell as frequent FPS fluctuations in games like BF3 and Crysis. While I realize some variation in average FPS is normal my last system never had this issue, My minimum FPS frequently dips down to 15 in BF3 since the switch to Ivy Bridge. I am lead to believe it may be the motherboard holding me back which Is why I posted in the Intel Motherboard section. Below is a list of things I've tried in order to resolve this issue.

~The List of Trials and Tribulations~ Check for things I've tried (Click to show)
* Reseating GPU
* Confirming 3D clocks kicking in
* Reinstalling drivers
* Updating to Beta drivers
* Rolling back to 296.10 drivers(Drivers used on my old system)
* Using driver sweeper and reinstalling latest official drivers
* Updating all 136 Windows updates (Temporary fix, didn't last)
* Updated BIOS
* Checking all system drivers for updates(None Found)
* Overclocking CPU from 3.5Ghz to 4.0Ghz (Shouldn't have had to OC at all)
* Switching out GPU with secondary GPU(Attempt at verifying dying GPU-No success)
* Turning off HyperThreading (No success)
* Moving GPU to x16 Lane(No FPS gains)
* Checking Vram usage(Never maxes out)

There may be a few other things I've tried but all these attempts have been spread out over a week or so.
BF3 Ultra Benchmarks (Click to show)
BF3 Fraps Benchmark Results - Ultra - FOV: 90 - Single GTX480 - (Min/Avg/Max)
AMD X6 @4Ghz - 32.7 / 52.6 / 103.5
I7 3770K @4Ghz - 23.2 / 42.9 / 97.4

The results for the I7 bench normally come out at around that average but I have seen them lower several times.

As I'm sure you all know these averages are unusual for the GTX480 and I refuse to believe it's my GPUs, I however do believe it may be the motherboard. It surely can't be the CPU so it must be the motherboard, I am after all mixing Ivy bridge with a Z68 chipset. I'm unsure though as to whether even that could cause this odd problem. If nobody can figure out what the issue is I'm going to be ordering a new Z77 motherboard to rule out this being an issue.

Edit:
Some of you may have seen this issue recently in the Nvidia Forum but seeing as I now believe this to be a motherboard issue I re-posted and cleaned up the contents to here.

The motherboard has little to no affect on performance. It's usually an issue with GPU, CPU, RAM, or PSU. I can almost guarantee you that the motherboard is not the problem.

Have you checked you temperatures? Especially the CPU. The CPU might be overheating, causing frame drops. Also, try using just one RAM stick. The PSU might be weak as well, but that Antec is good. Maybe it shorted out. Also, try a fresh install of Windows. This might clear up and bad drivers you installed or programs that caused poor FPS..

I'll look into it more and repost when I find info. If you truly believe it is the motherboard, try using your old motherboard/processor and see if it works then.

I wish I could use my old motherboard but sold it so I could upgrade, as for the CPU there's no way it's overheating during BF3 the highest I've seen the temps get is 46c. I have used driver sweeper to remove drivers before reinstalling. I will see what I can do about reinstalling windows, I have a spare SSD laying around I can test this with, however it probably won't be today that I try it because I will be needing my computer. redface.gif

I have used this PSU for almost a year now and the thought has crossed my mind that I should purchase a new PSU but I haven't had as much as a hiccup out of it yet. One of my friends has a system setup almost identical to my old AMD rig, even has the same CPU and motherboard, I will see if I can get him to let me borrow it for some tests but no guarantees though as he uses it for his college work. tongue.gif

Yeah, see if the PSU does the trick. In the mean time, I'll find out other things to check on

I got a hold of my friend with the computer that's like 90% the same as my old one and he said he will able to bring it over sometime this week, his computer also has a 100W cougar PSU so I can kill two birds with one stone. thumb.gif
