do you have any monitoring programs and overclocking if so disable your overclok reset it ot default, does it happen in other games aswell?

could be bad GDDR. I would return under warranty if possible. If you bought the card second hand it probably was sold with that fault. I found that using DX9 often helps keep the GDDR cool.

it could be your psu aswell, it doesn't have enough power, but it doubtful

Think im going to return it and buy a new one, had problems since day 1. Dont want to return it atall though as it plays games fantastic, just after 2-5 minutes freezes my whole PC up.

Is their anything you guys think i should try as a last resort?

well if you have access to a beefier PSU certainly try it (maybe a friends rig?). To check if it is the GDDR you can try to underclock the memory on the card using an OC tool and also use the tool to set fan speed to 100%. If that solves the crashing then it was likely the GDDR.

If it is the GDDR then a return is the way to go. If it is the PSU then you really will need to get a higher power unit.

500w is a bit low apparently. Minimum recommended PSU is a 550w. Might be the PSU. But if you return the card they tend to test it and if they don't find an issue with it then you should consider upgrading your power supply

Possibly a PSU issue. Which model Coolermaster is it? The CX500? Have you tried a different PCI-E cable or a different port on the PSU if it is a modular?

Also, are you sure your CPU isn't the 3570k? There is no 3330k. Are you overclocking either the CPU or GPU or both? Your motherboard has another PCI-E slot, have you tried it in that one?


Sorry mate yeah its the 3570k, sorry, ill try it in the other PCIE slot now, give me a few minutes to get back to you, but for the record i had a GTX 560TI in that slot for around a year and that worked flawlessly

EDIT - the psu is the RS-500

In my experience with GPUs and VRAM, if one or more of the VRAM were bad the GPU itself would usually still work but there would be serious artifacts. Unless all of the GDDR5 chips have gone bad or somehow the solder has weakened on all of them and they are starting to lose contact then it I am leaning toward a GPU core problem or power issue. The OP should look at the card for any visible signs of warping. It is hard to tell if the BGA of a VRAM chip is bad by simply looking at it since it is under the chip but a warped PCB could cause that as well as insufficient contact with the cooling pads.


Just installing new drivers for this PCIE express slot with my gfxcard in. This is the exact card and where i bought it from http://www.ebay.co.uk/itm/Gainward-Nvidia-GeForce-GTX-6...

Whatever you do, do it fast. The seller will only accept returns within 30 days. No warranty otherwise. Check the PSU fast, because if it is a faulty card you could be left stung.

Most likely the power supply.
yours is the eXtreme series. Which should only be ran at 75% of rated output. Above that it becomes very inefficient and the power gets really dirty.
Tier 4 in the following chart.

EDIT - the psu is the RS-500

That model PSU has 2 separate +12v rails of 18 amps each. The 670 requires that the PSU has 30 amps on the +12v rail but that is assuming that the PSU only has a single +12v rail. Your PSU has a total of 36 amps across both rails. Since there is only one PCI-E power cable on it and it is not SLI or crossfire compatible, I am assuming the GPU is on a separate rail as it would be the only logical way to design it. Unfortunately this is not a quality unit nor is it ideal for a modern CPU and GPU such as the ones you have. You should look for a PSU with a single +12v rail of at least 30 amps, 550 watts or higher and preferably 80+ rated - even if your PSU isn't the problem.


Is their anyway for me to test the Grapics card to make sure that its not the problem here as i will buy a new Psu today. Just want to be sure that when it arrives i wont be swamped with the same problem? Really appreciate your help on this

EDIT - Could you reccomned me any models that would be suited for this type of setup.

I recently had GPU issues and was pointed in the direction of a Corsair TX750 psu, that was for my GTX780 so not sure if that's overkill for a 670 or what? Maybe link us to a website where you're likely to buy a PSU from and give us your budget and someone I'm sure will come along and point you in the direction of one that will do.

Was thinking about this? what do you guys think, i could have it by tomorrow and tell you guys if its solved. If not then obviously return my graphics card, was intending to get a PSU anyway

The CX600 is a good choice. While not super high end, it will be a big step or two above what you currently have. The +12v rail has more than enough amps at 46A and Corsair is a very good company.


Ill buy this now, and hopefully have a positive result tomorrow! Ill keep this thread open until tomorrow after ive installed the psu etc, incase it doesnt work. Thanks for the help guys!!!

Just bought a 650w powersupply and the problem still persists...so it defiantly wasnt and isnt the PSU. Any other suggestions of what it could be? Im starting to lean toward a faulty card.

Best solution

Send it back and buy a different card. That is my advice.

After all the trouble shooting none of it worked, so the best answer goes to the one first proposed. Already been parceled up and its on it way back!
