(adsbygoogle = window.adsbygoogle || []).push({}); My GPU is totaly garbage. EVGA GTX 670 PhysX CUDA 2GB. It wont overclock AT ALL, the drivers keep crashing on me even I'm on stock clocks and the HDMI input is kinda "loose" so it breaks my HDMI cables.(Two so far) I also see artifacts under heavy load and hot temperatures. I've contacted the distributor and they say that they will replace it but I don't really want to send this piece of shit in just to get another piece of shit back. I'll try and get my money back and upgrade it for the 680.


I have a few questions tho.

- Is something bottle necking it? i5 2500K @stock, 8GB Vengeance RAM and 750W Corsair PSU.
- And when I upgrade it for a 680, will that be bottle necked?

Iknow the 2500K is a stong processor so I doubt it... but just to make sure. :p

No you wont be seeing any bottlenecks with a 2500k. And nothing is bottlenecking your current 670, it's just a defective card. I had a similar issue with my 580, where the drivers kept crashing and the card showed artifacts on boot and while gaming. I eventually came to realize that it was just a defective card and I returned it and picked up a brand new 580 3GB.

Frankly the 670 is not a bad card, but I can see your frustration. I was tempted to get my money back and get a 6970 at the time, but I knew the 580 was better and was still the king of GPU's. (Long live the 580 ) Not all 670's are going to give you these problems. Most of them are quite overclockable and run cool as long as you increase the fan speed.

Assuming you have a card that has extra power phases, try to increase the voltages on the card. The stock 600 series of cards don't allow for voltage increases, which is pretty stupid if you ask me. Perhaps your card is not getting all the power it needs.

The card has been returned, but I don't know what's going to happen yet, either I get my money back or they send me a new card. Either way, if I get my money back I'll either get a 4GB 670 or a 2GB 680. They have pretty much the exact same price, and if not its only like a 100 bucks apart. What would be the best thing to do, and if I get a new card in return, should I keep it or sell it for another model 670/680?

Even if I upped the voltage to 1175 mV it kept on either crashing the drivers or the application. Also I had a pretty beast fan curve. I had it running at 85% when hitting 69 degrees, so I don't think the fan speed had anything to do with it. =/

69 degrees at 85% fanspeed is not unheard of. It depends on the case, and the airflow in the case. If you have two fans blowing towards each other you are going to have a dusty and warm case, which is why I always avoid side panel fans or fans that blow air DOWN from the top of the case instead of blowing dust out. The voltage increase would also contribute to the temperature of the card.

Anyways, if you get the money back, the 2GB 680 will suffice for any games. Really you only need 4GB when playing at past 1920x1200 resolutions. If you dished out that kind of money for a 2560x1600 monitor, why are you only using one GPU

All jokes aside, get the 680 2GB if you get your money back. If they send you the same model, just use it. Make sure it's working properly, and that there's no issues. Are we talking about the EVGA version of the card? Literally all of the NVIDIA GPU's are made by excellent manufacturers. Zotac, Asus, MSI, EVGA, PNY etc. They're all excellent. So don't think that all of the cards you get from them are going to fail, you got unlucky to put it simply.

I do have a fan in the top of my case, should I take that out and install it in the grill instead? Also, my monitor is only 1080, so as you said I think that a single GPU should handle it pretty easy. Thanks for the advice Millz, and I will update the post when I either get my card or money back.

No. Almost all cases have fans on the top. As long as it's blowing air OUT of the case, then you should leave it. If it's the stock fan that came with the case, it's almost 100% blowing air out of the case, in which case you should leave it. The front fans intake air and the fans at the top and back suck the air out in order to allow new fresh air to come in.
