780 GTX - Power usage drops = FPS drops in ALL games - HELP!

Hello

I'm having a severe issue with my Palit 780 GTX.

When I play any game for about 2-3 minutes I get sudden FPS drops no matter what I am doing in game it'll run smooth again for a bit then drop again. I also notice that the power usage drops from 60-63% to 50-53%.

It has nothing to do with my GPU temp as it sits at about in game 50C

I have tried changing Nvidia control panel to 'prefer maximum performance'.
I have tried uninstalling/re-installing my drivers.
I have tried underclocking and overclocking.
I have tried k-Boost off and on.
I have reseating the card.

Games tested: Witcher 2, Farcry 3, Call of juarez: Gunslinger, BF4, Bioshock Infinite, Metro: last light. (All run perfectly until the GPU usage drops.)

My rig (brand new):
GPU: Palit GeForce GTX 780 Super Jetstream
CPU: AMD FX 9590
PSU: 850W
RAM: 16GB
Resolution: 1650 x 1050
Driver: 331.82

have you considered that its your cpu that's bottlenecking at that point, thats why the drops, or it could be running unstable aswell it just a oc'd 8350 anyway so there could be the reason, you power supply could also be having problems since that cpu draws unreal amount of power , try a different psu if you have any laying aroung or get one from a friend to try it out

try fresh installing the driver by uninstalling the driver and not restarting
run driver fusion nvidia driver cleaner then restart.
then install the latest driver on restart.

also remove avast if you use it, is a system hog and can cause all sorts of problems like this and system slowdowns.

I can't imagine a 9590 causing any bottlenecking?

Oh, I've also unparked my cores.

Yeah; I've tried doing a completely fresh driver uninstall/install. Same issue. :(

did you use driver fusion to clean any driver remnants?

if your psu has multiple pcie x6 connectors, try alternative ones/ slots if its modular incase one of the outputs is faulty.

well its slower than i7 4770k so it can cause bottlenceking

In Farcry 3: Blood Dragon I play it on ultra and the usage sits at 60-63%+ when its running well then drops to 50-53% when it runs like crap.

If I drop all setting to the lowest. It's 50-53% when it's smooth and drops to 20-30% usage when it runs like crap.

A 850W PSU with no spare pcie x6 connectors when only one GFX connected - sound suspicious...

ok as i said bfore its most likely your psu, that cpu and gpu combo could be to much for it

Well; I've just tried my 580 GTX and it's runs Blood Dragon like a dream on high with no FPS drop like it does on my 780 GTX.

My 580 GTX runs at higher temp and the fan speed is much higher.

I'm really suspecting it's a faulty 780GTX....

Going to call the company that built my PC tomorrow.

Well that rules out the PSU because the GTX580 has almost the same power requirement as the GTX780.
Could be another issue - maybe your PCIe slot doesn't run at full speed (you can check with GPU-Z) or maybe Nvidia doesn't fully support PCI-E 3.0 on your chipset look here :

Well I just got my new 780 GTX and the problem persists.

Here is the results in GPU-Z. http://postimg.org/image/4lm2e4ue5/

Notice the dip in GPU Load, Memory Controller Load and Power Consumption. That's when the fps is bad.

Well shit... As it turns out the 9590 isn't compatible with my M5 A97 LE R2.0 Mobo...

I feel like an idiot and kinda angry that the PC building place didn't know this.

Sorry for wasting your time guys. I appreciate all the help though.

Had I seen this earlier I could have saved you some time. Anyways, yeah, the 9590 is basically a factory "fucked" 8350, thus why they ship them with their own water blocks. At the moment very few mobo's fully support it, the closest I've seen is sabertooth but still requires some expensive thermals. I'm easily able to get my 8350 to the same speeds as the stock 9590, but I find that once you hit past 4.65GHz other things start operating a tad funny.

Glad you figured it out.

What I'm really annoyed about is a company that calls themselves 'PC Specialist' builds a PC for me that isn't even bloody compatible!

The reason I used this company is so I wouldn't have to do all the research and could just work around my budget...

I'm letting them have it tomorrow. Demanding a refund.

What I would do is demand a fixed amount off of the build from their mistake and then demand they replace the motherboard with one that supports your CPU (at their cost). If anything you can likely get them to drop their actual fees. In most cases I would say that's rather mean towards them as I do the same type of work, but that is a mistake nobody should be making that is doing it professionally, I would fire someone if I owned the business.
