Asus P8Z77-V PRO Throttling GTX 670 Performance?

[Zekrom]

I'm having issues with my new video card and I think it may be a problem with the motherboard.

I initially thought the video card might be defective, but after taking it out and trying it in a different system, I discovered that the card itself was not defective at all.

According to most reviews and benchmarks, this card (Gigabyte GTX 670) should score around 8000-9000 on 3DMark11 Performance preset. However, when I run the Performance benchmark, I only get a score of around 2000-3000.

Additionally, Unigine Heaven 3.0 on moderate settings only runs at around 20-30fps... this card should be getting 70+ fps in that program.

I've also been experiencing framerate drops and freezing/stuttering issues in Diablo 3, Skyrim, and Crysis 2. They will run at 50-60fps most of the time, but every now and then the sound will start clicking and the game will drop down to 2-3fps.


PC Parts:

CPU: Intel i5-3570K @ 3.4GHz

Motherboard: Asus P8Z77-V PRO

GPU: Gigabyte GeForce GTX 670 OC Windforce 3X

RAM: 12GB Corsair Vengeance DDR3-1600MHz

PSU: Corsair TX750M 750W

SSD: OCZ Vertex 3 90GB

HDD: Seagate Barracuda 1TB 7200rpm


I have reinstalled Windows.

I have updated to the latest nVidia drivers (301.42 WHQL).

I have updated my motherboard BIOS to the latest revision (Rev. 1015)

The card is in a PCIe 3.0 x16 slot.

The card runs at 1175MHz during benchmarks and games.

Temperature hovers around 50 degrees Celsius.

Power usage maxes out around 70%.

In the nVidia control panel, all settings are on Default; Ambient Occlusion is turned off, Power management mode is set to 'Prefer Maximum Performance' instead of 'Adaptive'.

Any help is appreciated!

RAM: 12GB Corsair Vengeance DDR3-1600MHz????????????????????????????????
-I don't have one [1155], but not sure if you can mix and match memory together that you have laying around.

What is the size and quantity of your memory? It could be running single channel. Check on that.

Also, Have you installed the motherboard chipset drivers? That does affect quite a few things performance wise.

For example I am running 4 x 2GB for a total of 8GB. If you are running 3 x 4GB for 12GB then you are probably losing performance due to the memory running in single channel.

I have 8GB (2x4GB) + 4GB (2x2GB), for a total of 4 DIMMs, all running in dual channel (4+4, 2+2) = 12GB total. The optimal configuration for this setup is 2/4/2/4, which is what I am using.

Ok. I just know a few people have forgotten that when changing from their triple channel boards to Z77 that they can only do dual channel.

I'm now wondering if you disabled turbo mode in the bios by accident. That could kill performance.

Something is definitely wrong, I have the same motherboard and GPU, and do get 9100-9200ish in 3DMark11 with factory settings on the video card. Sorry, nothing is coming to mind with what could be wrong.

You have verified that both the CPU and GPU are running at full speed during the benchmark right? I can see GPU is boosting to 1176, is the CPU somehow at 1600MHz?

Graphics card running PCI-e 3.0 x16?

Turbo would not affect performance to this extent at all. He should be getting between 3-400% more performance than he is actually getting. No way a 12% increase in CPU clock speed is going to have that effect on a GPU benchmark. Something else is going on. I have the same board with a 680 just ran Heaven at Moderate 1920x1200 and got 219.5/97.1/51.1 for Max/Avg/Min. His results should only be slighly lower with a 670 and a stock 3570k

I would check and verify you have it in the correct PCIe slot and not in the 2.0 4x one. Also make sure both the chipset and video drivers are up to date in addition to the boards bios. ASUS had an update for the pro a couple weeks ago.

EDIT: Just ran 3dmark for comparison and got 9421

set bios defaults?

Run a memory check, reduce your memory(remove the smaller dimms)

His usage is 99% so i'm pretty sure its just a driver issue.

His usage is 99% so i'm pretty sure its just a driver issue.

Log performance with GPU-Z, check log for GPU clock once you start getting slowdowns.

Zekrom did you find a solution to your problem?

I've had pretty similar issues with this board & exactly the same gpu?!

Any tips are pretty much appreciated! Any possible solution yet, Zekrom?
